发明背景 BACKGROUND OF THE INVENTION

1. 发明领域 1. Field of the Invention

本发明涉及一种用于脆性材料的锚,特别是用于安装于一部件的干墙的自钻锚。 The present invention relates to an anchor for a brittle material, in particular for drywall attached to a self-drilling anchor member.

2. 相关技术的描述 2. Description of Related Technology

因为干墙是脆性材料,在其上安装物件是困难的。 Because drywall is brittle material, it is difficult to install items on it. 过去,至少有3种方法被使用。 In the past, there are at least three kinds of methods are used. 对于重量轻的物件,小型塑料膨胀锚被使用。 For light weight articles, small plastic expansion anchors are used. 这种膨胀锚通常通 Such expansion anchors generally pass

过三个步骤来安装:首先,在干墙上钻一个孔;然后,锚被插入钻孔;最后, Through three steps to install: first, a hole is drilled in the drywall; Then, the anchor is inserted into the bore; and finally,

一个螺纹紧固件被插入钻孔,扩张此锚以和干墙接合。 A threaded fastener is inserted into the bore, and the expansion of this anchor to engage drywall. 然而,膨胀锚通常只能承受轻的载重。 However, expansion anchors typically can only withstand light load.

对于重负载的应用场合,系墙螺栓被使用。 For heavy duty applications, toggle bolts are used. 尽管系墙螺栓是有效的,但它们一般也是膨胀的,因为它们包含必须相对于另一部分移动的部分。 While toggle bolts are effective, they generally are swellable, because they contain must be moved relative to another portion of the part. 系墙螺栓也被认为难以安装。 Toggle bolts are considered difficult to install.

用于承受重负载的自钻锚也已经被使用。 Self-drilling anchor for absorbing heavy loads have also been used. 这些自钻锚通常通过锚自己钻入干墙。 These self-drilling anchors typically anchor themselves by drilling into drywall. 这样的锚还具有高的螺纹深度,以提供从干墙拔出的高阻力。 Such anchor also has a high thread depth, from drywall to provide high resistance to pull out. 自钻 Self-drilling

锚的例子包括ITWBuildex制造的、商标为E-ZANCOR的锚,以及美国专利4,601,625、 5,190,425和5,558,479公开的锚,这些专利均已转让给本申请的受让人。 Examples include anchors, under the trademark E-ZANCOR anchor, and U.S. Patent No. 4,601,625, 5,190,425 and 5,558,479 disclosed anchor ITWBuildex manufactured, these patents have been assigned to the assignee of this application.

自钻锚被证实可以在安装到千墙时有效承载较重负载。 Self-drilling anchor is effective when carrying a heavy load may be mounted to one thousand proven wall. 然而,在决大多数情况下,干墙被固定在用户看不到的木头支撑部件或栓上,通常用户不知道也没有检查支撑部件的位置。 However, in the overwhelming majority of cases, the dry wall is fixed to the user can not see the wood support member or bolt, usually does not know the user does not check the position of the supporting member. 当典型自钻紧固件的用户试图在支撑部件处安装锚到干墙时,锚无法钻入支撑部件,导致锚在原地旋转,锚的深螺纹剥 A typical self-drilling fastener when the user attempts to install the anchor into the drywall to the support member, the anchor can not penetrate into the support member, resulting in rotation of the anchor in place, screw anchor deep peeling

4落干墙,导致锚安装失败和墙上不好看的缺痕。 4 down drywall, lead anchor installation failures and lack of unsightly marks on the wall. 即使锚可以轻微地钻入支撑部件,锚会绷紧接合支撑部件并由于锚受的扭矩而断裂。 Even if the anchor can be drilled into the support member slightly, the anchor will engage the support member and tension anchor by torque due broken.

干墙锚通常具有一个头或凸缘,所述头或凸缘大于干墙螺纹的外部直径以防止安装锚时锚钻过干墙。 Drywall anchors typically have a head or flange or flange outer diameter larger than the head of the screw to prevent the drywall drilled anchor during installation drywall anchor. 然而,大的锚头会在推动锚时使干墙移位,导致此部分干墙环绕锚凸出,通常被称为干墙鼓包。 However, a large will cause the anchor head at the anchor is pushed drywall shift, resulting in dry wall surrounding this section projecting anchors, commonly referred to as drywall bulge. 干墙螺纹大的外部直径也会导致干墙移位和干墙鼓包。 Drywall thread, the outer diameter of the drywall will lead to displacement and drywall bulge. 干墙鼓包导致干墙表面的不美观的蓬松部分, 并难以使一些物件平齐于干墙表面地安装到干墙上。 Drywall cause unsightly bulge portion fluffy drywall surface, and it is difficult to flush some entities drywall mounted to the drywall surface.

从而需要一种可以减少干墙鼓包而不减少承载力的自钻锚。 Thus a need for a dry wall can be reduced without reducing the carrying capacity of the blister self-drilling anchor. 发明内容 SUMMARY

L prongs shown in a disconnected 4 and 7.

锚10用于脆性材料例如干墙1,所述干墙1安装在部件例如支撑部件2 上,此新的锚10具有: 一个伸长的具有轴6的本体12; —个用于接收紧固 Anchor 10 for a brittle material such as dry wall 1, a drywall 1 mounted on a member such as a support member 2, the new anchor 10 has: a body 12 having an elongated shaft 6; - a means for receiving the fastening

件4(见图7)的轴向腔8; —个在其中具有转矩传送面的张开端14; 一个最接近张开端14的近端部分18; —个中间部分20; —个远端部分22; —个一 4 (see FIG. 7) of the axial cavity 8; - in a flared end having torque transmitting surfaces 14; closest to a proximal end 14 flared portion 18; - intermediate portion 20; - a distal portion 22; - one a

般和张开端14相对的钻头16;其中近端部分18具有带螺纹的表面,例如接合干墙的螺纹19,所述螺纹19具有根部26和脊27,脊径为DC,螺纹深度为DH;中间部分20具有带螺纹的表面,例如接合部件的螺纹21,所述螺纹21具有根部28和脊29,脊径为MC, MC基本小于DC,螺纹深度为MH, MH基本小于DH;远端部分22具有带螺纹的表面,例如钻螺纹23,所述钻螺纹23具有根部30、脊31和螺纹深度TH,所述根部30呈锥形向钻头16 逐渐变细,所述脊31具有直径TC, TC基本小于DC, TH基本小于DH。 And generally opposite flared end 14 of the drill bit 16; wherein the proximal portion 18 having a threaded surface, such as drywall engaging thread 19, the thread 19 has a root 26 and the ridge 27, the ridge diameter of the DC, thread depth DH; intermediate portion 20 having a threaded surface, such as a threaded engagement member 21, the thread 21 has a root 28 and ridges 29, ridges diameter MC, MC substantially smaller than the DC, thread depth MH, MH substantially smaller than DH; distal portion 22 having a threaded surface, thread 23 such as a drill, the drill screw 23 having a root 30, the ridge 31 and the thread depth TH, the root portion 30 tapers conically towards the drill bit 16, the ridge 31 has a diameter TC, TC substantially less than DC, TH substantially smaller than DH.

如图7所示,锚10用于推入干墙1以安装一个物件3到干墙1。 As shown in FIG 7, the anchor 10 is pushed into drywall 1 for mounting an article 3 to drywall 1 to. 在锚10 被安装后, 一个装配紧固件4插透物件3进入锚10的腔8。 After anchor 10 is installed, a mounting fastener 4 is inserted through article 3 into the cavity 10 of the anchor 8. 锚10提供比单独的装配紧固件4更强的结合力和更大的拔出阻力。 Anchor assembly 10 provides a single fastener 4 than stronger binding force and greater pull-out resistance. 当仅仅锚IO被安装到干墙上时,锚10可以以类似传统的自钻锚方式被使用。 Only when the anchor is attached to the drywall IO, the anchor 10 may be used in a similar manner as a conventional self-drilling anchor. 然而,锚IO允许锚IO 穿入并和支撑部件2例如木质支撑栓结合,而增加承受将锚10推入干墙1和支撑部件2的巨大力量的强度。 However, the anchor penetrates IO and IO allows the anchor member and the support pin 2 is supported e.g. wood binding, increase the withstand strength of the anchor 10 is pushed into drywall 1 and support member 2 of a great force.

脆性材料可以是用于建筑的几种脆性材料中的一种,其中希望安装物件3到此脆性材料以增加此脆性材料可以承受的负载量。 Brittle material may be one of several brittle material for construction, in which the article 3 is mounted to this desirable to increase the loading of a brittle material this brittle material can withstand. 脆性材料的一个例子是基于石膏的干墙1,例如United States Gypsum销售的、商品名为SHEETROCK的石膏干墙.。 Examples of a brittle material is gypsum based drywall 1, for example, United States Gypsum sold under the trade name SHEETROCK gypsum drywall .. 干墙的厚度T通常为1/2或5/8英寸,但也可以是其他厚度,例如3/8英寸。 Drywall thickness T is generally 1/2 or 5/8 inch, but may be other thicknesses, such as 3/8 inch.

脆性材料例如干墙1通常被安装到一个部件上,例如木结构的支撑部件、 夹板、或另一个脆性材料例如另一层干墙。 Brittle materials such as drywall 1 is typically mounted to a member, such as the support structure of the wood member, plywood, or another brittle material such as another layer of drywall. 此部件可以是一个支撑部件2, 例如一个木质支撑部件,例如一个2X4的栓或类似物,他们彼此按均匀间距例如16英寸被放置,此部件或者可以是金属支撑部件,例如金属支撑栓。 This member can be a support member 2, such as a wood support member, for example a 2X4 bolt or the like, for example, 16 inches by uniform distance from each other they are placed, this may be a metal member or the support member, such as a metal support pins. 支撑部件相对于干墙1基本能抵抗拔出,因为支撑部件相对来讲很不容易裂开。 With respect to the supporting member 1 substantially resistant drywall removed, since the support member relatively very easy to crack. 尽管锚10可以用于安装在另一层干墙上的干墙1、或其他脆性材料,本发明 Although anchor 10 can be used in drywall mounted to one another drywall, or other brittle material, the present invention

将描述用于例如木质支撑栓的支撑部件的锚。 It will be described for anchoring wooden support member such as the support bolt.

参看图7,安装紧固件4优选是一个螺纹紧固件,例如一个安装螺丝, 具有细长的杆34、位于一端的一个顶部35、位于另一端的一个钻头36。 Referring to Figure 7, mounting fastener 4 is preferably a threaded fastener, such as a mounting screw, having an elongate lever 34, one top 35 at one end, at the other end a drill bit 36. 安装紧固件4的杆34包括螺纹5,所述螺纹5和锚10的腔8接合。 Mounting fastener 344 includes a threaded stem 5, the threaded cavity 10 of the anchor 5 and 8 engage. 安装紧固件4的螺纹5可以是标准的螺纹,例如Unified Coarse (UNC)或者Unified Fine (UNF)螺纹,或者螺纹5可以是特殊的螺纹。 Mounting the threaded fastener 54 may be a standard screw, e.g. Unified Coarse (UNC) or Unified Fine (UNF) threads, or threads 5 may be a special thread. 安装紧固件4可以是UNC 标准的#6、 #7或#8螺丝,其中顶部35具有菲利普斯式螺钉凹槽,总长度FL介于约1/2英寸一约2英寸或更多,优选约1.25英寸。 UNC mounting fastener 4 can be a standard # 6, # 7 or # 8 screws with the top 35 has a Phillips screw groove, the total length FL of between about 1/2 inch by about 2 inches or more, preferably about 1.25 inches. 安装紧固件7的螺纹密度介于约8螺纹每英寸到约18螺纹每英寸,优选15螺纹每英寸。 7 threaded fastener mounting density between about 8 threads per inch to about 18 threads per inch, preferably 15 threads per inch.

安装紧固件4可以具有不同的长度以适合物件3的不同厚度AT。 Mounting fastener 4 can have different lengths to accommodate different thicknesses AT 3 of the article. 优选地, 锚10被设计得如果物件3如图7所示相对较薄, 一个长的安装紧固件4可以和锚10—起使用,或者相对较厚,这时需要更长的长度以和锚IO接合。 Preferably, the anchor 10 if article 3 is designed to be relatively thin as shown in FIG 7, a long mounting fastener 4 can be used since the anchor 10-, or relatively thick, it requires longer time and length IO anchor bonding. 如同下面将描述的一样,锚10允许使用长于锚10的安装紧固件4,因为锚10 具有这样的形状:允许安装紧固头36穿过钻头16的原始位置。 As will be described below, the anchor 10 allows the use of fastener 10 is longer than the anchor 4 is mounted, since the anchor 10 has such a shape that: allows mounting fastener head 36 of the drill bit 16 passes through the home position. 因为锚10允许安装紧固件4的安装紧固头36穿过钻头16的原始位置,锚10可以比安装紧固件4短。 Because anchor 10 allows the installer to install the fastener 36 passes through the fastening head 4 of the original position of the drill bit 16, the anchor fastener 10 may be shorter than the mounting 4. 一个较短的锚10是所期望的,因为它限制支撑部件2的嵌入深度,因此减少相应的安装扭矩,也因为这样使得制造不那么昂贵、易于操作和在安装过程中保持稳定,也因为这样使得安装推入时间较短,因而用户可以在相对较短的时间内较容易得安装多个锚10。 A shorter anchor 10 is desirable because it limits the depth of embedding of the support member 2, thereby reducing the corresponding installation torque, but also because it makes manufacture less expensive, easy to operate and remain stable during installation, because of this so that the mounting push short time, so the user can easily get to install a plurality of anchors 10 in a relatively short compared with the time.

继续参考图7,当锚10被安装时,优选地锚10具有一个装置来允许紧固头36延伸超过锚10的钻头16的原始位置。 With continued reference to FIG. 7, when the anchor 10 is mounted, preferably anchor 10 has a home position to allow the fastening means 36 extends beyond the anchor head 10 of the drill bit 16. 锚10可以有一个允许安装紧固件4穿过锚10的薄壁38这样紧固头就能够延伸通过锚10的钻头16。 Allowing the anchor 10 may have a thin wall mounting fastener 4 through the anchor 38 so that the fastening head 10 can extend through the anchor 10 of the drill bit 16. 薄壁38允许锚10的根径更小,从而导致被要求的安装扭矩更低。 Thin wall 38 allows the root diameter of the anchor 10 is smaller, resulting in lower torque is required to install. 另外,薄壁38允许锚10接受具有相对较大外直径的安装紧固件4,而锚10仍有相对较小的根部。 Further, the thin wall 38 allows anchor 10 has a mounting fastener receiving a relatively large outer diameter 4, while the anchor 10 is still relatively small root. 例如,如果壁的厚度为约0.02英寸,并有一套足够大的键槽44, 如下所述,锚10能够接受一个外直径为约0.14英寸的# 6的带螺纹的安装紧固件,或者一个外直径为约0.16英寸的將的带螺纹的安装紧固件,而安装紧固件螺纹5不会攻入壁38。 For example, if the wall thickness is about 0.02 inch, and have a sufficiently large keyway 44, as described below, anchor 10 can receive a mounting fastener outer diameter of about 0.14 inches threaded # 6, or an outer mounting fastener having a diameter of about 0.16 inches to threaded, threaded fastener 5 is attached to wall 38 without scoring. 同样的,薄壁38允许锚10由较少的材料制成, 这样生产锚10就比较便宜。 Similarly, the thin wall 38 allows anchor 10 is made of less material, the anchor 10 thus produced relatively cheap. 在一个实施例中,锚壁38的厚度在约O.Ol英寸,和约0.05英寸之间,优选地在约0.015英寸和约0.03英寸之间,进一步优选地为约0.025英寸。 In one embodiment, the thickness of anchor wall 38 is between about O.Ol inches, between about 0.05 inches, preferably between about 0.015 inches and about 0.03 inches, more preferably about 0.025 inches.

在图3所示实施例中,键槽44被包括在用于接收安装紧固件4的锚10 的腔8之中。 In the embodiment shown in FIG. 3 embodiment, keyway 44 is included in a cavity for receiving a mounting fastener 4 of the anchor 10 among 8. 安装紧固件螺纹5啮合匹配的螺纹45进入键槽44中,这样安装紧固件4就与键槽44相接合,并由此与锚10相接合。 Engaging the threaded mounting fastener 5 into the matching threads 45 in the keyway 44, so that mounting fastener 4 to engage the keyway 44 and thereby engage anchor 10. 键槽44也给锚10 增加结构上的支撑,这样当其钻过干墙1和支撑部件2时锚10的本体12就能够承受较高的扭力。 Keyway 44 is also anchored to the supporting structure 10 is increased, so that when it is drilled through drywall 1 and support body member 10 of the anchor 12 2:00 can withstand higher torque.

带有键槽44的腔8的有效内直径应当小于外直径、或者安装紧固件4的脊径,但不能与安装紧固件4的根径一样小,这样键槽44被安装紧固件4攻螺纹以形成匹配的螺纹45。 The effective diameter of the inner chamber 8 with keyway 44 should be less than the outer diameter, or the diameter of mounting fastener 4 of the ridges, but not the same as the root diameter of mounting fastener 4 is small, so that the keyway 44 is mounted tapping fastener 4 thread 45 to form mating threads. 键槽44距壁38内部的高度优选地被选择得使腔8的内直径足够小以至于一个外直径为约0.136英寸的#6的有螺纹的安装紧固件4的螺纹能够攻螺纹于键槽44中;并且,使得壁38的内直径足够大以至于一个外直径为约0.164英寸的# 8的有螺纹的安装紧固件4的螺纹能够只攻螺纹于键槽44中而不攻螺纹于壁38中。 The keyway 44 from the interior wall 38 is preferably selected to be the height of the inner diameter of the chamber 8 such that a sufficiently small outer diameter of about 0.136 inches is threaded to # 6 threaded mounting fastener 4 can be tapped in the keyway 44 ; and such that the inner diameter of the wall 38 is large enough such that an outer diameter of about 0.164 inches to # 8 threaded mounting fastener 4 can only screw tapping in the keyway 44 in wall 38 without tapping in. 在一个优选实施例中,腔8在壁38处的内直径在约0.17英寸和约0.21英寸之间,优选地在约0.18英寸和约0.2英寸之间,进一步更优选地为约0.19英寸,而且键槽44的高度在约0.015 英寸和约0.045英寸之间,优选地在约0.025英寸和约0.035英寸之间,进一步优选地为约0.03英寸,这样腔8在键槽44处的有效内直径在约0.11英寸和约0.16英寸之间,优选地在约0.12英寸到约0.145英寸之间,进一步优选地为约0.13英寸。 In a preferred embodiment, the inner diameter of the chamber 8 in the wall 38 between about 0.17 inches and about 0.21 inches, preferably between about 0.18 inches and about 0.2 inches, still more preferably about 0.19 inches, and the keyway 44 a height between about 0.015 inches and about 0.045 inches, preferably between about 0.025 inches and about 0.035 inches, more preferably about 0.03 inches, so that the effective inner diameter of the chamber 8 in keyway 44 of about 0.11 inch and about 0.16 inches between, preferably between about 0.12 inches to about 0.145 inches, more preferably about 0.13 inches.

制造锚10的材料要足够坚固,能够承受通常条件下锚IO钻进干墙1和支撑部件2的扭力;还要有足够的延展性,能够被有螺纹的安装紧固件4攻螺纹。 Material of the anchor 10 to be strong enough to withstand normal conditions IO drilling drywall anchor 1 and support member 2 of the torque; also have sufficient ductility to be capable of threaded mounting fastener 4 tapping. 锚10的材料优选地为通过安装紧固件4可穿透的或者易破的以便安装紧固件4的钻头36能够延伸通过锚10的钻头16。 Anchor for the material 10 is preferably penetrable by mounting fastener 4 so that mounting of the frangible drill or fastener 364 can extend through the anchor 10 of the drill bit 16. 此外,制造锚10的材料要能够即简单又便宜地形成锚IO特定的几何结构。 Furthermore, the manufacturing materials of the anchor 10 can be simply and inexpensively be formed in the anchor IO specific geometry. 锚IO可以由能够模铸造成锚10的形状的金属或者金属合金制成,例如锡合金、铝合金、镁合金、铜、 青铜或者黄铜合金、以及锌合金。 IO anchor can be caused by the shape of the anchor can be made of die cast metal 10 or metal alloy, such as tin alloys, aluminum alloys, magnesium alloys, copper, bronze or brass alloys, and zinc alloys. 在一个实施例中,锚10由一种锌合金制成, 例如Zamac 1 ,辛合金。 In one embodiment, the anchor 10 is made of a zinc alloy, such as Zamac 1, octene alloy.

锚10也可以由塑料或者其他聚合材料制成,例如一种工程塑料如Delron、 尼龙、填充尼龙,如玻璃纤维尼龙。 Anchor 10 may be made of plastic or other polymeric materials, such as engineering plastic such as Delron, nylon, filled nylon, such as glass filled nylon. 但是,锚10应该被制成足够坚固能够承受锚10钻进干墙1和支撑部件2的扭力。 However, anchor 10 should be made strong enough to withstand the drilling drywall anchor 10 and the support member 1 2 of the torsion.

远端部分 The distal portion

回到图1到图4,远端部分22允许锚10在被使用者手工操作时钻过干墙1和支撑部件2,这样就不需要一个单独的先钻孔步骤。 Returning to FIG. 1 to FIG. 4, the distal portion 22 allows anchor 10 drilled through drywall 1 and support member 2 is manually operated when a user, eliminating the need to drill a separate step. 远端部分包括一个钻头16,而且在一个如图2所示的优选实施例中,钻头16通常为圆锥形并与本体12同轴,这样钻头16在本体轴6上达到点46。 The distal end portion includes a drill bit 16, and in the illustrated preferred embodiment a in FIG. 2, the drill bit 16 is generally conical and coaxial with the body 12, so that the drill bit 16 reaches the point 46 on the body shaft 6. 优选地,钻头16 包括一个其引导作用并迅速与干墙1的表面48和支撑部件2的前表面相接合的尖端46。 Preferably, the drill guide 16 comprises a tip thereof and rapidly acting contact with the surface of the front surface 48 of drywall 1 and support member 2 is bonded to 46. 如图6所示,钻头16还可以包括一个位于钻头16较低部分的平坦部分52,其作用在于帮助锚10与干墙1和锚10与支撑部件2的最初的接合。 6, the drill bit 16 may also include a flat 16 located in the lower portion of the bit portion 52, which functions to help initial engagement with the anchor 10 and drywall anchor 1 10 of the support member 2.

远端部分22包括一个具有钻孔螺纹23的有螺纹的外部,其被设置于远端部分22上用于接合干墙1和支撑部件2。 The distal end portion 22 comprises a threaded bore having a threaded exterior 23 which is disposed on the distal end portion 22 for engaging drywall 1 and support member 2. 钻孔螺纹23包括一个根部30和一个具有脊径TC的脊31,所述脊径TC基本小于干墙接合螺纹脊径DC,并且螺纹深度TH基本小于干墙接合螺纹深度DH。 23 includes a threaded bore root portion 30 and a ridge 31 having a ridge diameter of TC, TC substantially smaller than the ridge diameter drywall engaging thread ridge diameter of the DC, and a thread depth TH substantially smaller than drywall engaging thread depth DH. 钻孔螺纹深度TH也足够小以便钻入支撑部件的安装扭矩能够典型地由使用者手工完成,这样锚10就能够钻入支撑部件2。 Drilling thread depth TH is also small enough to drill into the support member installation torque can be typically accomplished manually by the user, so that the anchor 10 can drill into the support member 2. 螺纹23还可以包括在图3中可见的一个在螺纹23的基底部和根部30之间的曲率半径,以防止在螺纹23的基底部形成应力的集中。 Thread 23 may also include a radius of curvature between the base portion and the root portion 30 of the thread 23 visible in FIG. 3, to prevent the formation of stress concentration at the base portion 23 of the thread.

继续参考图2、 3,钻孔螺纹根部30从中间部分20向钻头16逐渐变细, 这样靠近钻头16的钻孔螺纹的横截面积相对于其在中间部分20上的横截面积是减小的。 Sectional area continued reference to Figure 2, 3, drilling thread root 30 tapers from intermediate portion 20 to the drill bit 16, so that the threaded bore near the drill bit 16 relative to its cross-sectional area of ​​the intermediate portion 20 is to reduce of. 钻孔螺纹23的螺纹深度TH实质上沿远端部分的长度保持不变。 TH threaded bore 23 thread depth remains substantially constant along the length of the distal portion. 但是,由于根部30相对较小,特别是在钻头16处,螺纹深度可能较大,例如大于部件接合螺纹21的螺纹深度MH,因为较小的根部30在脊径TC不太大时允许较大的螺纹深度。 However, because the root 30 is relatively small, particularly in the drill bit 16, the thread depth may be larger, for example greater than the depth of the screw thread 21 of the engagement member MH because smaller at the root of the ridge 30 allows for a larger diameter is not too large TC thread depth.

远端部分螺纹23和中间部分螺纹21接合干墙1并驱动锚IO通过干墙1。 The distal end portion of the threaded portion 23 and the intermediate thread 21 engages drywall 1 and drive anchor IO through drywall 1. 如果锚10被驱进到一个位置,其中一个支撑部件2位于干墙1后面,钻头16碰到支撑部件2,而且如果支撑部件2比干墙1相对要硬,例如一个木质的支撑栓,那么锚10典型地旋入干墙1而没有轴向地进入支撑部件10,在这里称为停顿。 If anchor 10 is driven into a position in which a support member 2 is located behind drywall 1, the drill bit 16 across the support member 2, and if support member 2 than dry wall a relatively stiff, for example a wooden support pin, then typically, the anchor 10 is screwed into drywall 1 without axially into the support member 10, referred to herein as a pause. 当锚10停顿,远端部分螺纹23和中间部分螺纹21在干墙1 上钻出一个预设尺寸的洞而钻头16钻进支撑部件2。 Pause when the anchor 10, the distal end portion of the screw thread 23 and the intermediate portion 21 in a preset size drywall drilled hole on the drill bit 16 and a drill support member 2. 最终钻头16钻入支撑部件2—定的深度,通常在约1/8英寸和约1/4英寸之间,使远端部件能够与支撑部件2相接合并开始驱动锚10通过支撑部件2和干墙1 ,这样千墙接合螺纹19能够与干墙1相接合。 The final drill bit supporting member 16 2- given depth, typically between about 1/8 inch and about 1/4 inch, the distal end member 2 can start driving with the anchor member 10 is engaged with and supported by the support member 2 and dried 1 wall, so that one thousand wall 19 can engage the threads engaged with drywall 1.

由中间部分螺纹21钻入干墙1的洞的尺寸被发现对于干墙和干墙接合螺纹W之间产生的接合很重要,特别是当锚10仅被驱进干墙的时候。 The size of the hole drilled into the intermediate threaded portion 21 of drywall 1 and was found to be dry wall drywall engagement between the threads to produce W is important, especially when the anchor 10 is driven into drywall only time. 我们发 Us

ii现,干墙螺纹具有一个约1/2英寸的脊径,这对于在干墙上钻出一个直径为约1/4英寸的洞是很理想的。 ii now, drywall screw having a diameter of about 1/2 inch ridges, which for dry drilling a wall diameter of about 1/4 inch hole is very desirable. 因此,远端部分22被设计为在干墙1上钻出一个洞,所述洞通常最大化锚10的拔出阻力到实际能达到的最大程度。 Thus, the distal end portion 22 is designed to drill a hole in drywall 1, anchor pull out the hole typically maximize resistance to the maximum extent practical to achieve 10.

继续图2,远端部分22可以包括至少一个翼54,所述翼54从远端部分22放射状地向外突出,用于在干墙l中刮出一个具有预定尺寸的洞,以最大化干墙的拔出阻力,特别是当仅锚10被驱入干墙、而在安装位置后没有支撑部件2时。 Continuing with Figure 2, distal portion 22 may comprise at least one flap 54, the flap 54 protrudes from the distal end portion 22 radially outwardly for drywall l scraped in a hole having a predetermined size, to maximize dry wall pull-out resistance, in particular when only the anchor is driven into the drywall 10, without the support member 2 in the mounted position. 优选地,翼54从轴6延伸到约等于邻接凸缘40的近端部分18的根部半径处,其中所述根部半径是根径DR的一半。 Preferably, wing 54 extends from the shaft 6 to the proximal end of the flange 40 abuts approximately equal to the radius at the root portion 18, wherein the root radius is half of the root diameter DR. 翼54被设计得当碰到支撑部件2时脱离,这样翼54不刮支撑部件2,而只刮干墙l。 Wings 54 are designed properly hit the support member 2 when disengaged, so that blade 54 does not support the wing member 2, and drywall only scraping l.

在图2所示实施例中,远端22具有一对从远端部分22放射状地向外突出的翼54。 In the embodiment shown in FIG. 2, it has a pair of distal end 22 from the distal end portion 22 radially outwardly projecting wing 54. 翼54沿远端22周缘均匀设置,因此这对翼54相隔180° 。 Wing 54 along the peripheral edge of the distal end 22 arranged uniformly, so this pair of wings 54 separated by 180 °. 翼54放射状地向外突出,这一对翼54之间的宽度WW约等于邻接凸缘40的近端部分18的根径DR。 Wings 54 protrude radially outwardly, the width WW between the proximal end of wings 54 is approximately equal to the root diameter of the flange 40 abutting portion 18 of the DR. 优选地,翼54刮出的洞约等于根径DR,这样翼54 仅刮出刚好必要多的干墙1,留下最大量的干墙1以和干墙接合螺纹19接合。 Preferably, airfoil 54 is approximately equal to the hole scraped root diameter DR, so that the wings 54 need only just scraped much drywall 1, leaving a maximum amount of drywall and drywall 1 to 19 engaging threaded engagement.

如前所述,如果钻头16碰到支撑部件2,钻头16钻入支撑部件2,将有一个瞬间的停顿,这样锚10上的螺纹开始刮掉部分干墙1。 As described above, if the support member 2 across the drill bit 16, drill bit 16 the support member 2, there will be a momentary pause, so the threads on the anchor portion 10 starts drywall 1 is scraped off. 由于这个原因, 重要的是:钻螺纹23接合支撑部件2,远端22快速钻入支撑部件2使得锚10在被驱向前之前不会过多刮掉干墙1,避免在干墙1表面产生疤痕。 For this reason it is important that: the drill screw 23 engages the support member 2, the distal end 22 the support member 2 quickly so that anchor drill 10 before being driven forward without much drywall 1 is scraped off, to avoid a dry wall surfaces scarring. 钻螺纹23延伸到尽量接近钻头16的轴位置,这样钻螺纹23可以更快地和支撑部件2接合。 Drilling thread 23 extends as close as possible to the position of the shaft 16 of the drill bit, so that drilling may engage threads 23 and the support member 2 faster. 在一个优选实施例中,钻螺纹23充分延伸到钻头16,这样,如图1、 2、 5所示,钻螺纹23的头和钻头点46的轴向距离介于约0英寸到约0.06英寸之间,当此距离为O英寸时,钻螺纹23实质上一路延伸到钻头16。 In a preferred embodiment, thread 23 extends substantially into the drill bit 16, such as 1, 2, 5, the drill head 23 and a threaded axial distance drill point 46 is between about 0 inches to about 0.06 inches between, when this distance is O inch drill thread 23 extends substantially all the way to the drill bit 16. 理想地,钻螺纹23优选一路延伸到钻头16, g卩,在钻头点46和钻螺纹23 的头之间没有距离,然而,已经发现对于一个成为一个点的钻头,其中根径实质上为O英寸,钻螺纹实际上变成轴,这使得钻螺纹难以和支撑部件2接合。 Ideally, the drill screw 23 preferably extends all the way to the drill bit 16, g Jie, no distance between the drill head and the drill point 46 of the screw 23, however, it has been found to be a bit of a point, wherein the root diameter is substantially O inch drill screw shaft actually becomes, which makes it difficult to drill threaded engagement and the support member 2. 因为这个原因,钻螺纹23的头56可以和钻头16稍微分开例如约0.02 英寸的距离。 For this reason, the drill head 56 threads 23 and the drill bit 16 can be slightly separated from, for example, about 0.02 inches.

锚10需要具有足够的结构强度以承受大的扭力而不会崩溃,特别是在钻头16处。 Anchor 10 needs to have sufficient structural strength to withstand a large torque will not collapse, especially in the drill bit 16. 如上所述,薄的壁38会导致锚10崩溃的潜在趋势,当驱动锚10 As described above, the thin wall 38 will cause the collapse of the underlying trend anchor 10, when driving the anchor 10

现,干墙螺纹具有一个约1/2英寸的脊径,这对于在干墙上钻出一个直径为约1/4英寸的洞是很理想的。 Now, drywall screw having a diameter of about 1/2 inch ridges, which for dry drilling a wall diameter of about 1/4 inch hole is very desirable. 因此,远端部分22被设计为在干墙1上钻出一个洞,所述洞通常最大化锚10的拔出阻力到实际能达到的最大程度。 Thus, the distal end portion 22 is designed to drill a hole in drywall 1, anchor pull out the hole typically maximize resistance to the maximum extent practical to achieve 10.

继续图2,远端部分22可以包括至少一个翼54,所述翼54从远端部分22放射状地向外突出,用于在干墙l中刮出一个具有预定尺寸的洞,以最大化干墙的拔出阻力,特别是当仅锚10被驱入干墙、而在安装位置后没有支撑部件2时。 Continuing with Figure 2, distal portion 22 may comprise at least one flap 54, the flap 54 protrudes from the distal end portion 22 radially outwardly for drywall l scraped in a hole having a predetermined size, to maximize dry wall pull-out resistance, in particular when only the anchor is driven into the drywall 10, without the support member 2 in the mounted position. 优选地,翼54从轴6延伸到约等于邻接凸缘40的近端部分18的根部半径处,其中所述根部半径是根径DR的一半。 Preferably, wing 54 extends from the shaft 6 to the proximal end of the flange 40 abuts approximately equal to the radius at the root portion 18, wherein the root radius is half of the root diameter DR. 翼54被设计得当碰到支撑部件2时脱离,这样翼54不刮支撑部件2,而只刮干墙l。 Wings 54 are designed properly hit the support member 2 when disengaged, so that blade 54 does not support the wing member 2, and drywall only scraping l.

在图2所示实施例中,远端22具有一对从远端部分22放射状地向外突出的翼54。 In the embodiment shown in FIG. 2, it has a pair of distal end 22 from the distal end portion 22 radially outwardly projecting wing 54. 翼54沿远端22周缘均匀设置,因此这对翼54相隔180° 。 Wing 54 along the peripheral edge of the distal end 22 arranged uniformly, so this pair of wings 54 separated by 180 °. 翼54放射状地向外突出,这一对翼54之间的宽度WW约等于邻接凸缘40的近端部分18的根径DR。 Wings 54 protrude radially outwardly, the width WW between the proximal end of wings 54 is approximately equal to the root diameter of the flange 40 abutting portion 18 of the DR. 优选地,翼54刮出的洞约等于根径DR,这样翼54 仅刮出刚好必要多的干墙1,留下最大量的干墙1以和干墙接合螺纹19接合。 Preferably, airfoil 54 is approximately equal to the hole scraped root diameter DR, so that the wings 54 need only just scraped much drywall 1, leaving a maximum amount of drywall and drywall 1 to 19 engaging threaded engagement.

如前所述,如果钻头16碰到支撑部件2,钻头16钻入支撑部件2,将有一个瞬间的停顿,这样锚10上的螺纹开始刮掉部分干墙1。 As described above, if the support member 2 across the drill bit 16, drill bit 16 the support member 2, there will be a momentary pause, so the threads on the anchor portion 10 starts drywall 1 is scraped off. 由于这个原因, 重要的是:钻螺纹23接合支撑部件2,远端22快速钻入支撑部件2使得锚10在被驱向前之前不会过多刮掉干墙1,避免在干墙1表面产生疤痕。 For this reason it is important that: the drill screw 23 engages the support member 2, the distal end 22 the support member 2 quickly so that anchor drill 10 before being driven forward without much drywall 1 is scraped off, to avoid a dry wall surfaces scarring. 钻螺纹23延伸到尽量接近钻头16的轴位置,这样钻螺纹23可以更快地和支撑部件2接合。 Drilling thread 23 extends as close as possible to the position of the shaft 16 of the drill bit, so that drilling may engage threads 23 and the support member 2 faster. 在一个优选实施例中,钻螺纹23充分延伸到钻头16,这样,如图1、 2、 5所示,钻螺纹23的头和钻头点46的轴向距离介于约0英寸到约0.06英寸之间,当此距离为O英寸时,钻螺纹23实质上一路延伸到钻头16。 In a preferred embodiment, thread 23 extends substantially into the drill bit 16, such as 1, 2, 5, the drill head 23 and a threaded axial distance drill point 46 is between about 0 inches to about 0.06 inches between, when this distance is O inch drill thread 23 extends substantially all the way to the drill bit 16. 理想地,钻螺纹23优选一路延伸到钻头16, g卩,在钻头点46和钻螺纹23 的头之间没有距离,然而,已经发现对于一个成为一个点的钻头,其中根径实质上为O英寸,钻螺纹实际上变成轴,这使得钻螺纹难以和支撑部件2接合。 Ideally, the drill screw 23 preferably extends all the way to the drill bit 16, g Jie, no distance between the drill head and the drill point 46 of the screw 23, however, it has been found to be a bit of a point, wherein the root diameter is substantially O inch drill screw shaft actually becomes, which makes it difficult to drill threaded engagement and the support member 2. 因为这个原因,钻螺纹23的头56可以和钻头16稍微分开例如约0.02 英寸的距离。 For this reason, the drill head 56 threads 23 and the drill bit 16 can be slightly separated from, for example, about 0.02 inches.

锚10需要具有足够的结构强度以承受大的扭力而不会崩溃,特别是在钻头16处。 Anchor 10 needs to have sufficient structural strength to withstand a large torque will not collapse, especially in the drill bit 16. 如上所述,薄的壁38会导致锚10崩溃的潜在趋势,当驱动锚10进入支撑部件2时,薄的壁38提供很少的支持以抵抗锚10承受大的扭力。 As described above, the thin wall 38 will cause the collapse of the underlying trend anchor 10, when driving the anchor 10 into the support member 2, a thin wall 38 to provide little support against the anchor 10 to withstand high torque. 因为这个原因,锚IO、特别是钻头16具有加强件。 For this reason, anchor IO, in particular a drill 16 has reinforcement. 钻螺纹23对钻头16提供结构加强作用。 Drill threads 23 provide structural reinforcement effect of the drill bit 16. 此结构加强作用是重要的,因为驱动锚10进入支撑部件2 时会产生大的扭力,特别是当锚壁38薄而不能自己提供强的结构支持时。 Strengthening the role of this structure is important because the anchor driven into the supporting member 10 generates a large torque 2:00, especially 38 to provide a thin and strong structure can not support its own when the anchor wall.

继续参考图l、 2,远端部分22的外部螺纹23可以包括两个通常为螺旋形的排列成双螺旋的螺纹23'、 23"。螺纹23'、 23"的双螺旋结构提供了围绕远端部分22的附加的支持,用于帮助防止远端部分22由于驱动锚IO进入支撑部件2的扭力而崩溃。 With continued reference to FIG. L, 2, distal portion 22 of the external threads 23 may comprise two generally arranged in a double helix of the helical thread 23 ', 23. "Thread 23', 23" of double helix structure is provided around the distal additional support end portion 22, distal portion 22 to help prevent the drive member supporting the torsion anchor into the IO 2 of collapse. 双螺旋螺纹23'、 23"也提供平衡的驱动进入支撑部件2以及钻头16与支撑部件2更紧密的接合。另外,双螺旋螺纹23'、 23"延伸到一个最接近钻头16的轴向位置,这样锚10能够迅速接合并钻进支撑部件2中。 Double helical threads 23 ', 23 "also provide balanced driving into the support member 2 and the drill bit 16 closer engagement with the support member 2. Further, the double helical threads 23', 23" extend to an axial position closest to the drill bit 16 , so that anchor 10 can quickly engage and drill the support member 2.

优选地,每一个双螺旋的螺纹23'、 23"具有实质上相同的螺距P,这样螺纹23'、 23"中的一个不会超过另一个。 Preferably, each of the double helix threads 23 'and 23 "having substantially the same pitch P, so thread 23', 23" does not exceed one another. 优选地,第二螺纹23 "被轴向设置于距第一螺纹23'大约半个螺纹23'的螺距P的位置,例如当一个螺距P为约0.2英寸时就是0.1英寸,这样在沿远端部分22的每一个轴向位置上都有在任一边提供结构上的支持的螺纹23'、 23"。 Preferably, the second thread 23 'are axially disposed in position from the first thread 23' about a half thread 23 'of the pitch P, for example, when a pitch P of the distal end is about 0.2 inches is 0.1 inches, so that along each axial position of the threaded portion 22 on either side are provided on the support structure 23 ', 23. " 优选地,双螺旋的螺纹23'、 23" 具有实质上相同的螺纹深度TH。 Preferably, the double helix threads 23 ', 23 "having substantially the same thread depth TH.

双螺旋的第一螺纹23'延续成为中间部分20上的螺纹21而第二螺纹23" 只存在于远端部分22上。螺纹23'、 23"也都能够以双螺旋延续到中间部分20 上(没有画出),为中间部分20提供与远端部分22相同的结构上的支持。 The first thread of the double helix 23 'on the continuation of an intermediate thread 20 and the second portion 21 thread 23 "is only present on distal portion 22. The threads 23', 23" can be also a double helix portion 20 continues to the intermediate (not shown), the intermediate portion 20 is provided on the distal end of the support 22 of the same moiety. 如果第二螺纹23"延续到中间部分上,它将提供与支撑部件2的进一步的接合。 If the second thread 23 "continues on the intermediate portion, a further engagement will provide the support member 2.

如上所述,允许安装紧固件钻头36延伸通过锚10的钻头16是所期望的, 这样使用者就能够使用不同长度的安装紧固件4。 As described above, the drill bit 36 ​​to allow mounting fastener extends through the bit 16 of the anchor 10 is desirable, so that the user can use mounting fasteners 4 of different lengths. 但是,如果当安装紧固件4 开始钻入支撑部件2时锚10没有充分地与支撑部件2相接合,安装紧固件4 的转动将导致安装紧固件螺纹5把锚10拉退出干墙1,即所谓的"顶托", 这将导致锚10的彻底损坏并导致干墙接合螺纹19使干墙1出现破损留痕。 However, if, when mounting fastener 4 begins to drill into support member 2 the anchor 10 is not fully engaged with the support member 2, mounting fastener 4 will cause rotation of the threaded fastener 5 mounted pull anchor 10 exits drywall 1, i.e., so-called "jacking," which will cause irreversible damage and lead to the anchor 10 threads 19 engage drywall 1 so that drywall appears damaged traces. 当安装紧固件4被钻进支撑部件2时,通过部件接合螺纹21和钻孔螺纹23 使锚10和支撑部件2实质地接合来防止顶托的出现。 When the fastener 4 being drilled mounting support member 2, by engaging a threaded member 21 and threaded bore 23 so that the anchor 10 and the support member 2 to engage substantially prevent backwater. 如果安装紧固件4没有 If mounting fastener 4 does not

中间部分 The middle section

13刺穿或者穿过锚IO,中间部分20的部件接合力并不严重。 13, or piercing through the anchor IO, the intermediate portion of member 20 engaging force is not serious. 但是,锚10与支撑部件2充分的接合仍然是需要的,因为与支撑部件2的接合是锚10的紧固值的主要贡献来源。 However, sufficient bonding the anchor 2 with the support member 10 is still needed, the support member 2 because engagement with the main contributor to the anchor 10 of the fastening values.

参看图2、 3,部件接合螺纹21被设置于中间部分20上并包括一个根部28和一个脊29,所述脊29的脊径MC基本小于干墙接合螺纹的脊径DC。 Referring to FIG. 2, 3, the screw engaging member 21 is disposed on the intermediate portion 20 and includes a root portion 28 and a ridge 29, the ridge 29 ridge diameter of the MC substantially smaller than drywall engaging thread ridge diameter DC. 在图2所示的实施例中,中间部分20的根部28通常为圆锥形,这样根部28朝远端部分22逐渐略微变细以便于安装锚10时特别是在木质的支撑部件上安装锚10时所需要的扭矩被最小化,因为这可以使得中间部分20的根径MR 和脊径MC更小。 In the embodiment illustrated in Figure 2, the intermediate 28 root portion 20 is generally conical, so that the distal end portion 22 toward the root portion 28 is slightly tapered so as to gradually anchor installation in particular mounting anchor 10 on the support member wood 10:00 the torque required is minimized, as this may cause the middle portion and the root diameter MR 20 MC diameter smaller ridges. 在一个实施例中,部件接合螺纹根部28以一个介于约1/2 度和约4度之间的角度逐渐变细,优选地为约2.25度。 In one embodiment, the engagement member between the thread root 28 at an angle a of between about 4 degrees and about 1/2 of the tapers, preferably about 2.25 degrees.

最大的中间部分的脊径被优先地选择得使干墙接合螺纹19和干墙1之间的接合最大化,特别是当锚IO仅被安装于干墙中时。 The maximum diameter of the ridges of the intermediate portion is preferentially selected such that drywall engaging thread 19, and maximizing engagement between drywall 1, particularly when the anchor is only attached to the IO dry wall. 例如, 一个锚10的干墙接合螺纹直径DC为约1/2英寸,那么最大的部件接合螺纹直径MC为大约1/4英寸或者更小是理想的。 For example, an anchor 10 engages drywall thread diameter DC of about 1/2 inch, then the maximum thread diameter MC engagement member is about 1/4 inch or less is desirable.

与下面描述的干墙接合螺纹19相比,部件接合螺纹21的螺纹深度MH 基本小于干墙接合螺纹191的螺纹深度DH。 Drywall described below compared to engage the threads 19, the screw member 21 engaging thread depth MH substantially smaller than drywall thread depth DH engage the threads 191. 中间部分20的脊径MC也基本小于近端部分18的脊径DC,这样在支撑部件2 (例如一个木质栓)中所需要的安装扭矩不会过大。 MC-diameter intermediate spine portion 20 is also substantially smaller than the ridge diameter of the proximal end portion 18 of the DC, so that the support member (e.g. a wooden peg) 2 installation torque required is not excessive. 部件接合螺纹21的脊径MC和螺纹深度MH被优先选择为足够小,这样上述锚10在钻入支撑部件2而停顿时不会使干墙1受损留痕或者戳破干墙1,并且在停顿中部件接合螺纹21不会和干墙1相接合, 所述的中间部件接合螺纹21与干墙1的接合会将干墙1顶托离开支撑部件2。 Thread ridges engaging member diameter MC and thread depth MH 21 is preferentially chosen to be sufficiently small so that the above-described anchor 10 is drilled into the drywall will not make the supporting member 2 and a pause burst or damaged traces drywall 1, and Dwell engage the threaded member 21 will not engage drywall 1, engaging the intermediate member 21 away from the support member and the threaded drywall will engage drywall 1 1 2 backwater.

虽然中间部分20和远端部分22的较大的螺纹深度MH、 TH会导致支撑部件2中较高的拔出阻力,还会基本提高驱动锚10进入木质的或者其他材料的支撑部件所需要的扭矩,造成使用者安装锚10的困难,特别是在使用手动的螺丝刀时。 While the intermediate portion 20 of the thread depth larger portion 22 and a distal MH, TH will result in a higher pull-out resistance of the support member 2, the anchor 10 will substantially increase in driving into the wood or other support member materials required torque, causing the user to install the anchor 10 is difficult, particularly when using a manual screwdriver. 因此,在选择螺纹深度MH、 TH时应当考虑到在中间部分20 被驱入支撑部件2时的可以接受的扭矩。 Thus, the choice of the thread depth MH, TH should be considered when the intermediate portion 20 is driven into support member 2 may be accepted torque.

在图1所示的实施例中,中间部分20的螺纹21是一个通常为螺旋形的螺纹21,是一个钻孔螺纹23'的延续并延伸到干墙接合螺纹19上(下面将述及)。 In continuation of the embodiment shown in FIG. 1 embodiment, the intermediate threaded portion 20 21 is a generally helical thread 21, it is a threaded bore 23 'extends into and engage the threads on the drywall 19 (mentioned below) . 中间部分20的外部螺纹21也可以与远端部分22中相同为双螺旋,可以为中间部分20提供附加的结构上的支持。 20 is an externally threaded intermediate portion 21 may be the same as in the distal portion 22 of the double helix, it may provide additional structural support to the intermediate portion 20. 中间螺纹21在螺纹21的基底部和根部28之间也有一个曲率半径以防止在螺纹21基底部形成应力的集中。 An intermediate base portion between the thread 21 and root 28 of the thread 21 also has a radius of curvature to prevent formation of a stress concentration at the bottom of the thread 21 group.

中间部分20和远端部分22的长度之和ML优选地大于干墙1的厚度T, 这样当锚10在开始钻入支撑部件2之前停顿时,近端部分18的较大脊的螺纹19 (下面述及)不会与干墙1接合,所述螺纹19与干墙1的接合会趋向于剥脱干墙1并在干墙1的表面留下一个大疤痕。 The length of the intermediate portion 20 and distal portion 22 and preferably greater than ML drywall thickness T 1, ie, when the anchor 10 so that a pause before beginning to drill into support member 2, the larger proximal end portion 18 of the thread ridge 19 ( mentioned below) is not engaged with drywall 1, engaging the thread 19 and drywall 1 will tend to peel the dry wall surfaces 1 1 and left in a large scar drywall. 长度ML应当足够长以便于远端部分22在干墙接合螺纹19开始与干墙1相接合之前完成在干墙1上的钻孔,特别是在锚10仅被驱进干墙时。 Length ML at 22 should be long enough to engage the threads when the drywall 19 starts with drywall 1 before the engagement created on the drilling drywall 1, particularly in the anchor 10 is driven into drywall only the distal end portion. 这是优选的,因为在钻入一种材料时,沿轴向向前驱进穿过这种材料基本慢于使用螺纹驱进穿过这种材料。 This is preferred because, when drilling into a material along the axial direction through the intake of such precursor material substantially slower than driving into threaded through this material. 例如,使用干墙接合螺纹19驱动锚10沿轴向穿过干墙1要比锚10钻孔进入干墙1快的多。 For example, dry wall anchor 10 engages the drive screw 19 axially through drywall 1 than the anchor into the drywall 10 drilling a much faster. 如果在干墙接合螺纹19开始与干墙1接合之前钻孔步骤没有完成,那么干墙接合螺纹19很可能会剥脱干墙1而不是驱动锚10穿过它。 If the drywall engaging thread 19 starts engagement with drywall 1 before drilling step is not completed, then the drywall engaging thread 19 are likely to peel drywall 1 rather than drive anchor 10 through it. 另外,平衡中间部分20和远端部分22的长度之和ML与驱动锚10所需要的安装扭矩是很重要的,特别是在支撑部件2中。 Further, the intermediate portion 20 and the length of the balance of the distal end portion 22 and ML 10 with the drive anchor installation torque required is very important, especially in the supporting member 2.

继续图l、 2所示的实施例,中间部分20包括用于结构支持的肋58。 Continuing with FIG. L, embodiment illustrated in Example 2, intermediate portion 20 includes ribs 58 for structural support. 优选地,肋58轴向延伸并径向略微突出于中间部分20的根部28。 Preferably, ribs 58 extending axially and radially intermediate portion slightly protrudes to the root 20 of 28. 肋58也可以被设置于近端部分18或者远端部分22,用于在支撑部件2中钻孔或者攻螺纹时提供更多的沿锚10的结构上的支持。 Ribs 58 may be provided in the proximal portion 18 or distal portion 22, for drilling in the support member 2 or to provide more structural support along anchor 10 when the tapping.

在一个优选实施例中,锚10包括一个钻孔螺纹23',23"的双螺旋结构和轴向肋58,它们协同形成一个围绕远端部分22和中间部分20的支撑笼或者支撑格架,用于防止由于驱动锚10进入支撑部件2产生的高扭力而导致的锚10 的崩溃。 In a preferred embodiment, the anchor 10 includes a threaded bore 23 ', 23 "of double helix and axial ribs 58, which cooperate to form a support around distal portion 22 and intermediate portion 20 of the cage or the support grid, for preventing collapse due to the driving anchor 10 into the support member 2 to produce the high torque caused by the anchor 10.

近端部分 A proximal portion

参看图l一4,近端部分18包括一个当锚IO停顿时用于与干墙1接合的有螺纹的外部,这样物件3的负载将由干墙1承受,特别是锚IO仅被驱进干墙时。 Referring to Figure 4 a l, proximal portion 18 includes a threaded exterior, such a load object when the anchor 1 IO pause for engaging drywall and drywall 1 by 3 bear, in particular the anchor is driven into dry only IO when the wall. 干墙接合螺纹19将一个匹配的螺纹60形成于干墙1中,这样干墙接合螺纹19与干墙1之间的接合就完成了。 Drywall screw 19 engages a matching thread 60 formed in drywall 1 so that drywall engagement between the thread 19 and drywall 1 is completed. 有螺纹的外部包括设置于近端部分18上的螺纹19,所述螺纹19具有一个脊径为DC的脊27和一个根径为DR 的根部26。 It comprises a threaded external threads 18 disposed on a proximal portion 19 of the threaded ridge 19 having a ridge 27 of diameter DC and a root diameter DR of root 26. 干墙接合螺纹19是一个深螺纹,其中脊27和根部26之间的距2 离或者螺纹深度DH相对于部件接合螺纹21和钻孔螺纹23要大。 Drywall engaging thread 19 is a thread depth, wherein the depth of the thread or the distance from the DH 2 between the ridges 27 and root member 26 engage the threads 21 relative to the threaded bore 23 and larger. 深的干墙接合螺纹19有助于使干墙接合螺纹19与干墙1接触的表面积最大化,提高拔出阻力。 Deep drywall engaging threading 19 helps to maximize the surface area of ​​drywall engaging thread 19 in contact with a dry wall, improving pull-out resistance. 干墙接合螺纹19的螺纹深度DH基本大于部件接合螺纹21和钻孔螺纹23的螺纹深度MH、 TH,这将在干墙1中提供较高的拔出阻力。 Threaded drywall engaging thread depth DH 19 is substantially larger than the screw member engages the threaded bore 21 and the thread depth MH 23, TH, which will drywall 1 provides higher pull-out resistance. 干墙接合螺纹脊27的直径DC可以沿近端部件18的全长基本上保持不变。 Full length diameter DC of drywall ridges 27 may engage the threads of the proximal member 18 remains substantially unchanged. 在一个实施例中,脊27的直径DC是大约根部26的直径DR的两倍。 In one embodiment, the diameter of the ridges is twice the DC 27 about the root diameter DR 26.

参看图5,优选为大约干墙接合螺纹19的3/4转被接合于干墙1的后面, 这样干墙接合螺纹19在干墙1的后表面50上与纸51相接合。 Referring to Figure 5, preferably about 3/4 of a turn of drywall engaging thread 19 is engaged behind drywall 1 so that drywall engaging threading 19 in drywall 50 and 51 engage the rear surface of the paper 1. 当驱动锚10 仅进入干墙时,在干墙后表面50上接合纸51是特别重要的,因为与纸51的接合提供了锚10和干墙1之间接合的一个重要部分。 When driving the anchor into the drywall 10 only, on the rear surface 50 engages drywall paper 51 is particularly important, because the anchor 10 and provided with engage drywall paper 51 is an important part of the engagement between the 1. 干墙接合螺纹19没有被设计成驱进支撑部件2中,因为深干墙接合螺纹19需要一个非常高的扭矩将锚10驱进支撑部件2中。 Drywall engaging thread 19 is not designed to be driven into support member 2 because the deep drywall engaging thread 19 requires a very high torque to drive anchor 10 into support member 2.

参看图2、 3,近端部分18的根部26向中间部分20逐渐变细,这样根部26通常呈圆锥形,而且这使得近端部分18顶端的根部26的直径大于近端部分18底部的根部26的直径。 Referring to FIG. 2, 3, root 18 of proximal portion 26 tapers toward intermediate portion 20 so that root 26 is generally conical, such that the root portion 18 and tip 26 is greater than the diameter of the proximal end of the proximal portion 18 of the bottom of the root diameter 26. 在图2所示的实施例中,近端部分18逐渐变细的根部26和中间部分20的逐渐变细的根部28是通常连续的并以相同的角度逐渐变细,这样根部26、 28沿相同的圆锥体延伸,使锚10成为一个弹道的或者子弹式的形状。 In the embodiment illustrated in Figure 2, proximal portion root 18 tapers gradually tapered root portion 26 and an intermediate portion 20 28 is generally continuous and in the same tapered angle, so that the roots 26, 28 in same cone extension 10 so that the anchor becomes a ballistic or bullet shape type.

在图1所示的实施例中,近端部分18的外部螺纹19是一个部件接合螺纹21的延续的螺纹19,只是干墙接合螺纹19具有一个脊径DC和螺纹深度DH,其中脊径DC基本大于中间部分20的脊径MD,而螺纹深度DH基本大于中间部分20的螺纹深度MH,参见图2、 3。 In the embodiment illustrated in Figure 1, the proximal end 19 of the outer threaded portion 18 is a continuation of the threaded member 19 engage the threads 21, but threaded drywall engaging ridge 19 has a diameter DC and a thread depth DH, wherein ridge diameter DC intermediate portion 20 is substantially larger than the diameter of the MD ridges, and substantially larger than the intermediate thread depth DH MH thread depth portion 20, see 2, 3 in FIG. 在一个实施例中,近端部分18的脊径DC大约是中间部分20的脊径MC的两倍。 In one embodiment, the diameter DC ridge proximal portion 18 is about twice the diameter of the intermediate portion 20 of the ridge of the MC.

优选地,在中间部分20和近端部分18中间有一个过渡区域62,其中脊径和螺纹深度从部件接合螺纹21到干墙接合螺纹19增大。 Preferably, the intermediate portion 20 and proximal portion 18 has an intermediate transition region 62, wherein the ridges and the diameter of the screw thread depth from the engagement member 21 to drywall engaging thread 19 increases. 在一个实施例中, 过渡区域62延伸大约一个螺纹圈的3/4。 In one embodiment, the transition region 62 extends about 3/4 of a thread turn. 如图1中所示,干墙接合螺纹19优选为通常的螺旋形。 Shown in Figure 1, drywall engaging thread 19 is preferably a generally helical shape. 干墙接合螺纹19也可以是一个如上所述的两个螺纹的双螺旋,其中双螺旋中的一个螺纹可以是一个细螺纹,所述细螺纹的螺纹深度基本小于干墙接合螺纹19的螺纹深度DH。 Drywall engaging thread 19 may be two threads of a double helix as described above, wherein a thread in the double helix can be a fine thread, the thread depth is substantially less than the fine thread depth of the screw thread 19 engages drywall DH. 双螺旋中的第二螺纹将为锚10 A second thread in the double helix will anchor 10

16提供附加的阻力。 16 provides additional resistance. 干墙接合螺纹19还可以包括一个在螺纹19的基底部和根部26之间的曲率半径,使干墙螺纹19的基底部的应力集中最小化。 Drywall engaging thread 19 may further comprise a radius of curvature between the thread root 19 and the base 26, the stress drywall screw base portion 19 minimize concentrated.

回到图2、 4,干墙接合螺纹19的上端被凸缘40隔开以形成在凸缘40 和干墙接合螺纹19之间的颈部64。 Returning to Figure 2, 4, the upper end of the thread 19 engages drywall flange 40 are spaced apart to form a neck 64 between flange 40 and 19 engage the threads of the drywall. 颈部64允许凸缘40的上表面41装在干墙表面48的水平或者低于这个水平,如图4中所示,在到达凸缘40之前的颈部64的干墙接合螺纹19的中断使得产生了一个位于干墙1内的螺纹60中的间隔,所述间隔允许通过凸缘40压紧邻近的物质。 Neck 64 allows upper surface 41 of flange 40 mounted on the horizontal surface 48 of drywall or below this level, as shown in FIG. 4, drywall neck 64 before reaching flange 40 engage the threads 19 of the interrupt positioned such that a dry wall screw 60 in the interval 1, the spacer allow the flange 40 adjacent the compacted material through. 此外,颈部64保证干墙接合螺纹19与干墙表面48上的纸49间隔开,这样干墙接合螺纹19不与纸49相接合并扭曲它而产生一个不期望的干墙表面48的外观。 In addition, the appearance of the neck portion 48 engage the threads 64 to ensure that the dry wall surface 19 and the paper 49 on drywall 48 spaced apart, so that drywall engaging thread 19 is not in contact with the paper 49 which generates a combined twist undesired drywall surface . 颈部64可具有一个介于大约0.03英寸和约0.1英寸之间的长度NL,优选为约0.07英寸。 A neck portion 64 may have a length NL range between about 0.03 inches and about 0.1 inches, preferably about 0.07 inches.

包括凸缘40的近端部分18的长度DL,优选为略微大于干墙1的厚度T, 如图4中所示,这样,优选地,就有一部分的干考接合螺纹19在干墙后表面50的后面与后表面纸51相接合。 Comprising a length DL of proximal flange 40 of portion 18 is preferably slightly larger than the thickness T 1 as a drywall, shown in Figure 4, so that, preferably, there is a portion of the threaded stem 19 engages in the test drywall surface the back surface of the paper 50 and the rear 51 engagement. 如果锚10被驱入支撑部件2的位置,那么谨慎地选择近端部分18的长度DL以平衡在干墙后表面50上与纸51相接合的干墙接合螺纹19的长度与驱动这个长度的干墙接合螺纹19进入支撑部件2 所需要的扭矩是很重要的。 If the position of anchor 2 is driven into the support member 10, the careful selection of the length DL of proximal portion 18 engage the threads 19 in order to balance the length of the length of the drive drywall rear surface 50 of drywall paper 51 is engaged drywall engaging thread 19 into the supporting member 2 torque required is very important. 另外,锚10可以用于不同厚度的干墙1是所期望的,所以提醒下述内容是很重要的:近端部分18的某一个长度DL允许螺纹19在一种厚度的干墙内与后表面纸51相接合,但是在另一种厚一些的干墙内又可能太短以至于不能接合后表面纸51,或者相反,近端部分18对一种较薄的干墙来说太长以至于太多的干墙接合螺纹19必须被驱进一个支撑部件,从而导致需要更高的安装扭矩。 Further, the anchor 10 can be used for different thicknesses of drywall 1 is desirable, so the following content alert is very important: a certain length DL of proximal portion 18 allows the thread 19 having a thickness in the dry wall and the rear engagement surface of the paper 51, but another dry thicker walls may be too short and engaging the rear surface of the paper 51, or the opposite, proximal end section 18 thinner drywall one kind is too long to As much drywall engaging thread 19 to be driven into a support member, resulting in a higher required installation torque.

千墙接合螺纹19的螺距P被优选得在干墙1中至少存在一整圈的干墙接合螺纹19,优选在约1.75圈到约2.25圈之间,进一步优选为嵌入干墙1的干墙接合螺纹19的2整圈。 One thousand walls 19 engage the threads of the pitch P is preferably obtained in the presence of at least one dry-wall one full turn of drywall engaging thread 19, preferably from about 1.75 to about 2.25 turns turns, more preferably embedded in drywall 1. Drywall 2 engaged threads 19 of full circle. 在一个实施例中,干墙1的厚度为1/2英寸或5/8 英寸,干墙接合螺纹19的螺距P在约l/8英寸和约0.3英寸之间,优选为约0.2英寸。 In one embodiment, the thickness of the drywall 1 is 1/2 inch or 5/8 inch, drywall engaging thread pitch P of between about 19 l / 8 inch and about 0.3 inches, preferably about 0.2 inches. 优选地,千墙接合螺纹19的螺距通常与部件接合螺纹21的螺距及钻孔螺纹23的螺距相等。 Preferably, one thousand thread pitch engaging wall 19 is generally equal to the pitch of engagement with the member 21 and the threads of the threaded bore 23 of the pitch. 在一个实施例中(未画出),最接近过渡区域的干墙接合螺纹19的螺距大于其余的最接近张开端14的干墙接合螺纹19的螺距。 In one embodiment (not shown), the pitch of drywall closest to the transition area engage the threads 19 is larger than the rest of the wall 14 nearest to the flared end of the dry pitch of the threads 19 of engagement. 当这个较大螺距的螺纹与干墙1相接合时,将锚10拉进干墙相对较快, When this large-pitch thread is engaged with drywall 1, anchor 10 into drywall relatively fast pull,

17有助于抵消任何可能发生的顶托。 17 help offset any backwater that might occur.

张开端 Zhang beginning

参看图l一4,凸缘40位于锚10的张开端14并包括一个与干墙接合螺纹根部26相比增大的直径FD,使得凸缘40能够与干墙前表面48上的纸49 接合。 Referring to FIG. L-4, the flange 40 is located at flared end 10 of anchor 14 and includes an enlarged diameter FD compared with a drywall engaging thread root 26, so that the flange 40 can be engaged with the paper 49 on front drywall surface 48. 在一个实施例中,凸缘40的凸缘直径FD在约0.45英寸到约0.6英寸之间,优选为约0.515英寸。 In one embodiment, the flange 40 of the flange diameter FD of between about 0.45 inch to about 0.6 inch, preferably about 0.515 inches. 凸缘40还包括转矩传送面15,这样锚10能够被使用者用一个起子旋转。 Flange 40 further comprising a torque transmitting surface 15, so that the anchor 10 can be a user with a screwdriver to rotate. 凸缘40可以包括一个用于接收起子43的尖端的孔穴42,参考图8,其中孔穴42被设计用于一种特殊类型的起子。 It may include a flange 40 for receiving a screwdriver tip 43 cavities 42, with reference to FIG. 8, wherein the aperture 42 is designed for a specific type of screwdriver. 孔穴42 是一个Phmips型孔穴用于接受一个Phillips型起子的尖端。 Hole 42 is a hole for receiving a Phmips type Phillips type screwdriver tip.

孔穴42具有一个大于腔8的内直径的有效直径以容纳起子43,这样在孔穴42处的锚壁38比其他沿锚10的轴向位置的锚壁38要薄。 A cavity 42 having an effective diameter larger than the inner diameter of the chamber 8 to accommodate driver 43 so that anchor wall 42 of the cavity 38 is thinner than the other axial positions along anchor 10. The anchor 38 wall. 由于锚10所经受的所有的扭矩趋向于被集中在孔穴42,张开端14可能在锚10被充分地驱动之前断裂,特别是当锚10被驱入支撑部件2时,这是因为驱动锚10进入支撑部件2需要高扭矩。 Since all torque experienced by anchor 10 tends to when it is concentrated in the apertures 42, the flared end 14 may be broken before the anchor 10 is fully driven, particularly if anchor 10 is driven into the support member 2 in, because driving the anchor into the 10 the support member 2 requires a high torque. 在一个如图3中所示的实施例中,锚10包括一个在孔穴42处加宽的壁39形成一个隆起66,用于加强孔穴42。 In one embodiment illustrated in Figure 3, the anchor 10 includes a widened wall 42 at a hole 39 is formed a ridge 66, a hole 42 for reinforcement. 具有隆起66 的加宽的壁39延伸整个孔穴42的轴向长度用于在驱动锚IO过程中充分地支持孔穴42。 The raised wall 66 widened apertures 39 extend the entire axial length of the anchor 42 for driving IO process to fully support the cavity 42.

在一个木质支撑部件2中木头的硬度和密度可以有很大的变化。 It can vary widely in density and hardness of the wood in a wood support member. 硬度和密度的变化导致在干墙1中装凸缘40所需要的安装扭矩的变化,所以凸缘40的后缘表面41与干墙表面齐平或者低于干墙表面。 Change in hardness and density results in a change in the drywall mounting flange 40 of the torque required 1 are installed, the surface of the trailing edge 40 of the flange 41 and drywall surface flush or below drywall surface. 此外,与仅仅驱动锚10穿过干墙1和支撑部件2相比,当在干墙中装凸缘40时驱动锚10所需要的扭矩显著上升。 Further, with only the drive anchor 10 through drywall 1 and support member 2 as compared to when the flange 40 in drywall installed with driving anchor 10 required torque increased significantly. 在一些情况下,安装扭矩的上升足够高以至于使用者必须施加一个很大的扭矩,所述很大的扭矩使使用者趋向于提供一个太大的扭矩, 不仅仅安装凸缘40而是过度旋转锚10并剥脱一些干墙1。 In some cases, installation torque increase is high enough that a user must apply a large torque, the large torque that the user tends to provide too large a torque, but only over the mounting flange 40 rotating anchor 10 and stripping some of the drywall 1. 当必需的安装扭矩太大(也就是大于50 in-lbs),使用普通的手动工具装凸缘40会变得很困难或者不可能。 When the required installation torque is too large (i.e. greater than 50 in-lbs), the use of ordinary hand tools installed flange 40 becomes difficult or impossible.

为了解决这个安装问题,锚10的凸缘40可以被修改以降低要求使用者提供的扭矩负载。 To solve this mounting problem, flange 40 of anchor 10 may be modified to reduce the torque load requirements provided by the user. 在一个实施例中(未画出),锚10不包括一个凸缘,或者包括一个直径小于干墙接合螺纹19脊径DC的凸缘,这样必需的安装扭矩实 In one embodiment (not shown), anchor 10 does not include a flange, or includes a smaller diameter than the diameter of the ridges 19 engage drywall DC threaded flange, so that the torque required to install a real embodiment

18质上被降低了。 18 quality is reduced. 这使得使用者更易于安装凸缘、或者锚10的后缘端,并降低 This allows the user easier mounting flange, or the trailing edge end 10 of the anchor, and lowered

过度旋转的可能性,因为扭矩增大被基本降低或者消除了。 The possibility of over-rotation because the torque is increased substantially reduced or eliminated.

断开凸缘 Disconnect the flange

【0059】锚10可以包括一个断开凸缘40',如图8中所示。 [0059] Anchor 10 may include a disconnect flange 40 ', as shown in Fig. 锚IO包括削弱部件的断开区域68,可以是例如划痕、凹口或者小洞来使凸缘40'在预设扭矩下断开,当驱动器43给锚10施加预设扭矩时,凸缘40'自锚本体12断开,以使用户无需安置凸缘40'。 IO anchor member including a weakened area 68 is disconnected, can be, for example scratches, recesses or holes, whereby the flange 40 'off at preset torque, when the preset torque is applied to drive the anchor 43 to 10, the flange 40 'is disconnected from the anchor body 12, so that the user need not disposed flange 40'. 断开区域68位于锚10的轴向位置上,因此当凸缘40'断开时,剩余的锚本体12未破损的部分是在干墙表面48水平位置或者在干墙表面48水平位置以下,因此锚10仍然是有功能的并能够接收安装紧固件4。 Disconnect the anchor region 68 is located on the axial position 10, and therefore when the flange 40 'is turned off, the rest of the anchor main body portion 12 is not damaged dry wall surface 48 in a horizontal position or in a drywall surface 48 or less horizontal position, Thus the anchor 10 is still functional and able to receive mounting fastener 4. 预设的凸缘40'的断开扭矩应当是一个预设的大于实质上驱动锚10的全长进入干墙1和支撑部件2通常所需要的扭矩,因此在凸缘40'断开时,剩余的锚10的最外的部分应当齐平于或者略微埋置于干墙表面48,从而提供了根据应用可能需要或者不需要进一步修整的漂亮完美的外观。 Pre-flange 40 'is turned off a predetermined torque should be substantially greater than the entire length of the anchor 10 is driven into the drywall second torque normally required and the support member 1, and therefore the flange 40' is turned off, the remaining outermost portion of anchor 10 should be flush or slightly embedded in drywall surface 48, thereby providing a beautiful appearance perfect trimming a further application might or might not.

本发明的锚的许多特征已经在上面被描述。 Many of the features of the anchors of the present invention have been described above. 作为本发明的例子,下面将讨论几个实施例。 Examples of the present invention, several embodiments will be discussed below.

断开尖头实施例 Example disconnected tip

参考图l一4和7,锚10的一个实施例包括至少中间部分20和远端部件22中的一个是易破的,这样安装紧固件4能够折断本体12的一部分16',参见图7,这样安装紧固件钻头36能够延伸越过钻头16的原始位置(参见图4)。 Referring to FIG 4 and a l-7, anchor 10 includes at least an intermediate portion of Example 20 and distal member 22 is a frangible, so that mounting fastener 4 can break portion 16 of the body 12 ', see FIG. 7 , so that the drill mounting fasteners 36 can extend beyond the original position of the drill bit 16 (see FIG. 4).

锚10的断开尖头实施例被设计成,当一个长于锚10的安装紧固件4被使用时,安装紧固件钻头36使锚10的钻头16折断或者断开锚10的钻头16, 以便于安装紧固件钻头36能够延伸得长于锚本体12,如图7所示,这样锚10和安装紧固件4的使用者能够使用特别长的安装紧固件4用于具有不同厚度的物件3,而不必担心锚10是否足够长以支持安装紧固件4。 Disconnect the anchor tip 10 embodiment is designed such that when a mounting fastener 10 is longer than the anchor 4 is used, mounting fastener anchor the drill bit 36 ​​10 16 16 break or disconnect the anchor 10 of the drill bit, the drill bit 36 ​​to facilitate mounting of the fastener can extend longer than anchor body 12, shown in Figure 7, so that the anchor 10 and mounting fastener 4 can be used particular user long mounting fastener 4 for having different thicknesses 3 article, without worrying whether the anchor 10 is long enough to support mounting fastener 4. 可选择地, 一个较短的安装紧固件4可以被使用,这样安装紧固件钻头36没有刺穿锚本体12,但仍保留在腔8中。 Alternatively, a shorter mounting fastener 4 can be used so that mounting fastener 36 without piercing drill anchor body 12, but remains in the cavity 8.

参看图4、 7,在锚10被安装之后,安装紧固件4被驱入腔8直到安装紧固件钻头36顶到内腔8的端点9。 Referring to FIG. 4, 7, after anchor 10 is installed, mounting fastener 4 is driven into the end chamber 8 until mounting fastener into the interior of the drill bit 36 ​​9 8.

继续图l一3的实施例,远端部分22包括一个锚本体12结构上的削弱部件以保证钻头16在希望的位置断开。 Example 3 a continuation of FIG. L, a distal anchor portion 22 comprises a weakened body structure member 12 is turned off to ensure that the drill bit 16 in a desired position. 削弱部件的一个例子是螺纹23上的一个裂缝,例如一个位于理想的轴向断开位置的纵向或者横向的凹口70。 An example of a weakening element is a crack in the thread 23, for example, one located over the axial longitudinal or transverse direction of the open position of the recess 70. 由于螺纹23提供了结构上的支持,螺纹23上的凹口70提供了锚本体12上的一个小面积的结构上的薄弱区域,所述的薄弱区域不能承受安装紧固件4顶压腔末端9产生的张力。 Since the thread 23 provides structural support, notch 23 in thread 70 provides an area of ​​weakness in the structure of a small area on the anchor body 12, the area of ​​weakness can not withstand the pressure chamber 4 mounting fastener tip 9 the tension produced. 凹口70还有助于防止螺纹23从安装紧固件4周围松脱,当安装紧固件4被从锚10中移除时,这会有助于防止锚10被拧出干墙1。 Recess 70 also helps to prevent the screw 23 from loosening 4 mounted around the fastener, when the fastener 4 is removed from the mounting anchor 10, which will help to prevent the anchor 10 is screwed out drywall 1. 在一个实施例中,凹口70的宽度是大约0.17英寸,进入螺纹的深度大约为0.03英寸。 In one embodiment, the width of the recess 70 is about 0.17 inches, a depth into the thread of about 0.03 inch.

参看图3,另一个削弱部件包括在理想的轴向断开位置造成一个在腔8 的直径上的尖锐的台阶72。 Referring to Figure 3, another weakening means comprises an open position caused by a sharp step 72 in the diameter of the chamber 8 at a desired axial direction. 台阶72允许形成应力的集中,这提高了钻头16 在台阶72处断开的可能性。 72 allows the step of forming a stress concentration, which increases the likelihood of the drill bit 16 is disconnected at the step 72. 其他的削弱部件包括位于钻头16的理想的断开位置的锚本体12上的凹槽或者小洞(未画出),例如一个在腔末端9的通常为圆锥形区域内的内部凹槽。 Other weakening means comprises a recess or hole in the anchor body 12 is located over the open position of the drill bit 16 (not shown), for example, a normal internal groove chamber for the conical end 9 region.

在一个图9、 IO中所示的钻分开尖头实施例中,远端部分22包括薄弱区域,例如一组均匀地轴向设置的向着钻头16轴向延伸的延伸裂缝74。 In a FIG. 9, the drill tip separately IO shown embodiment, the distal end portion 22 comprises a weakened area, such as a set of uniformly crack extending axially toward the drill bit 16 extends axially 74. 薄弱区域提供了远端部分22的壁38的削弱,当安装紧固件钻头36顶压腔末端9 时,允许安装紧固件4通常沿裂缝74'分裂远端部分22,如图10中所示。 Providing a weakened area of ​​weakness in the wall 38 of the distal end portion 22, the drill bit 36 ​​when mounting fastener tip 9 pressure chamber, allowing mounting fastener 4 generally along the slit 74 'split distal portions 22, 10 as shown in FIG. shows. 钻头16的分裂部分保持连接于锚本体12而且远端部分螺纹23保持与支撑部件2相接合,以提供一个锚10和支撑部件2之间的更强大的接合。 Splitting portion remains connected to the drill bit 16 is the anchor body 12 and distal portion threading 23 remains engaged with the support member 2 to provide a stronger engagement between the anchor and the support member 210.

参看图11一13, 一个锚10b的开罐器实施例被描述,其中至少中间部分20b和末端部分22b中之一的直径小于安装紧固件4的脊径或外部直径,这样安装紧固件的螺纹5可以穿透至少中间部分20b和末端部分22b中之一, 这样安装紧固件头36可以伸过钻头16b的原始位置。 Referring to FIG. 11 a 13, an anchor 10b opener embodiment is described, wherein the diameter of the at least one intermediate portion 20b and end portion 22b of the ridge is less than the diameter or the outer diameter of mounting fastener 4 so that mounting fastener threads 5 can penetrate through the at least one intermediate portion 22b and end portions 20b, so that mounting fastener head 36 extends through the drill bit 16b can original position. 如图13所示,腔8和末端部分22b或中间部分20b外表面之间的壁足够薄、足够接近轴6,使得安装紧固件螺纹5可以切入壁38b,沿锚本体12b的周边剪切使得钻头16b 和锚本体12b的剩余部分不再连接。 13, between the wall 8 or the intermediate portion 22b and the outer surface of the end portion 20b of the cavity is sufficiently thin, sufficiently close to the shaft 6, so that mounting fastener threads 5 can be cut into the wall 38b, cut along the perimeter of anchor body 12b and an anchor body 16b so that the remainder bit portion 12b no longer connected. 类似于图7中头16',钻头16b锚本体12b的剩余部分分开,并且和安装紧固件的头36保持接合。 7 is similar to FIG head 16 ', the remainder of anchor body 12b of the bit 16b separated, and mounting head 36 and the fastener remains engaged.

由于壁38b设置得接近轴6以允许安装紧固件螺纹5切入壁38b,中间部分20b的相应的根径MR'也较小,这样需要较小的扭矩来安装紧固件, 需要较少的材料来制造。 Since the wall 38b positioned proximate the shaft 6 to allow mounting fastener threads 5 cut into the wall 38b, 20b of the intermediate portion of the corresponding root diameter MR 'is small, this requires less torque to install fastener, less materials manufacturing.

锚10b也可以具有类似于断开尖头实施例中锚10的翼54的一套翼54b。 Anchor 10b can also have a similar anchor disconnected tip airfoil 54 Example 10 is a set of wings 54b. 在一个实施例中,翼54b轴向延伸,但没有刮刻干墙1表面的尖头。 In one embodiment, wings 54b extend axially, but without scratching the surface of the drywall tip 1.

如上所述,开罐器实施例中锚10b的近端部分18b和断开尖头实施例中锚10的相应部分具有近似相同的尺寸。 As described above, this embodiment can opener anchor proximal portion 18b 10b on and off the respective tip portions of the anchor 10 in the embodiment have approximately the same dimensions embodiment embodiment. 如图2所示,锚10b的中间部分20b 和锚10的中间部分20稍有差异。 Intermediate 10b intermediate portion 20b of the anchor portion 20 and the anchor 10 shown in Figure 2 is slightly different. 中间部分根部28b向末端部分22b縮小的角度基本大于末端部分26b縮小的角度,这样部件接合螺纹根部28b变得小于断开尖头实施例中部件接合螺纹根部28。 Intermediate portion root 28b to a reduced end portion 22b is substantially larger than the angle of the end portion 26b of the narrow angle, so that the engagement member 28b becomes smaller than the thread root tip disconnected embodiment engaging member 28 thread roots. 较小的部件接合螺纹根部28b允许安装紧固件螺纹5切入壁38b,从锚本体12b切除钻头16b的一部分。 Smaller member engages the thread root 28b allows mounting fastener threads 5 cut into the wall 38b, 12b of the body portion of the cutting bit from the anchor 16b. 在一个实施例中,中间部分20的根径MR'等于约0.16英寸到约0.22英寸, 优选为约0.2英寸。 In one embodiment, the intermediate portion 20 of the root diameter MR 'equal to about 0.16 inches to about 0.22 inches, preferably about 0.2 inch. 锚10b的远端部分22b的最大根径和脊径都小于断开尖头实施例中的相应值。 The distal end portion of anchor 10b and the root diameter of the maximum diameter of the ridges 22b is turned off is less than the corresponding values ​​prongs in the embodiment.

尖头绕过实施例 Tip bypass embodiment

参看图14一18,在另一个实施例的锚10c中,至少中间部分20c和22c 中的一个被安装紧固件头36剌入,这样安装紧固件头36可以迂回绕过钻头16c。 Referring to FIG. 14 a 18, in another embodiment of anchor 10c in the embodiment, at least the intermediate portion 20c and 22c is a fastener head 36 is mounted into the puncture, so that the fastener heads 36 may be mounted bypasses the drill 16c. 在图15所示实施例中,腔8c实质上没有延伸入中间部分20c,这样实质上整个中间部分20c和末端部分22c都是实心的,这一点在图15看得最清楚。 In the embodiment shown in FIG. 15, the cavity 8c does not extend substantially into intermediate portion 20c, so that substantially the entire intermediate portion 20c and distal portion 22c are solid, which is best seen in FIG. 15. 中间部分20c和末端部分22c中有很少或没有腔8c,这些部分可以具有 Intermediate portions 20c and 22c of the tip portion there is little or no cavity 8c, these portions may have

22较小的直径,这使得锚10c可以容易的被驱入干墙1和支撑部件2,因为需要较小的扭矩,从而使得锚10c可以较快的被驱入干墙1和支撑部件2。 22 small diameter, which makes anchor 10c can easily be driven into drywall 1 and support member 2 because it requires less torque, 10c so that the anchor can be driven into the faster drywall 1 and support member 2. 另外, 实心的中间部分20c和末端部分22c在结构上也更结实。 Further, the intermediate portion 20c and the tip portion 22c in the solid structure is stronger. 在一个实施例中, 中间部分20c的脊径MC〃等于约0.18英寸到约0.22英寸,优选为约0.2英寸,与上面描述的断开尖头实施例和开罐器实施例中锚10、 10b的脊径相比不同。 In one embodiment, the intermediate portion 20c of the ridge MC〃 diameter equal to about 0.18 inches to about 0.22 inches, preferably about 0.2 inches, for example, anchor embodiments 10, 10b examples and disconnect opener tip embodiment described above the ridge path different compared.

小头情形的实施例参看图22—24所示的实施例, 一个用于脆性材料例如干墙1的锚210包括:具有轴206的本体212; —个用于接收安装紧固件的轴向腔208; —个近端214; —个钻孔端216。 Example head embodiment with reference to the case of the embodiment shown in FIGS. 22-24, for a brittle material such as dry wall anchors 2101 comprises: a body having a shaft 206 212; - an axial mounting for receiving a fastener chamber 208; - a proximal end 214; - a drilled end 216. 一个邻近所述近端214的近端部分218,在此近端部分218具有用于和所述干墙1结合的螺纹219; —个邻近所述钻孔端216 的钻孔部分224。 A proximal end 214 adjacent the proximal end portion 218, this proximal portion 218 has a thread 219 and the drywall 1 binding; - one end of said bore adjacent the bore portion 224 216. 螺纹219直径为PR的根部226和直径为PC的脊227。 The root diameter of the screw 219 and the diameter 226 of the PC PR ridges 227. 位于所述近端214的头240具有外部直径HD, HD小于PC。 Located at the proximal head 240 has an outer diameter of 214 HD, HD is smaller than PC. 锚210包括在锚210被驱入干墙时帮助防止干墙1鼓包的技术装置。 Anchor 210 includes art devices help prevent bulge drywall 1 when anchor 210 is driven into drywall.

head

参看图23、 24,头240被设置成当锚210被驱入脆性材料例如干墙1时最小化干墙1的可见形变或者鼓包。 Referring to FIG. 23, 24, the head 240 is arranged such that when the anchor 210 is driven into a brittle material such as drywall 1 drywall minimize deformation of a visible or bulge. 头240具有直径HD,所述直径HD基本小于一般的锚的头和凸缘,例如图1一3所示实施例的凸缘40。 HD head 240 having a diameter, substantially less than the diameter of the head HD and the flange ships anchors, for example, a 1 3 of the flange 40 the embodiment of FIG. 头240的小的外部直径HD减少头240的面积,当锚210被固定时所述头240穿过干墙1 。 Small external diameter of the head 240 of the head 240 to reduce the area of ​​HD, when the anchor 210 by the head 240 through drywall 1 is fixed.

头240被连接到本体212近端214,包括一个用于驱动器例如起子的轴向凹槽242。 Head 240 is connected to the proximal end 214 of the body 212, for example, comprising a drive for the axial groove 242 driver. 凹槽242包括扭矩传送面215,所述扭矩传送面215允许驱动器施加扭矩到锚210以转动它。 Recess 242 includes a torque transmitting surface 215, a torque transmission surface 215 allows the application of torque to the drive anchor 210 to rotate it. 在图24所示的一个实施例中,凹槽242具有Phillips型(十字型)形状以接收一个Phillips式螺丝起子或者一个从驱动螺丝起子引出的Phillips式曲柄。 Phillips screwdriver drawn crank one embodiment, the groove 242 has a Phillips-type (cross-shaped) shaped to receive one or a Phillips screwdriver from the drive 24 shown in FIG.

头240具有外部直径HD,所述外部直径HD小于和干墙1接合的螺纹219的最大外部直径或脊径PC。 HD head 240 has an outer diameter, a thread 219 engaged with the outer diameter HD is smaller than the maximum outer diameter and the drywall or ridge diameter PC. 当锚210被驱动时,近端部分218的根部226 移动并在干墙1中钻出一个洞,因此,头240的直径HD优选尽量接近干墙螺纹219的根径PR,从而允许头240仅轻微的从干墙1中的洞突出,这样头240只需要在干墙1中进行一个小量的移动。 When the anchor 210 is driven, the proximal end portion of the root 218 and 226 move in a dry drill a hole in the wall, therefore, the diameter of head 240 is preferably as close to the root diameter HD PR drywall screw 219, thereby allowing the head 240 only drywall slightly protrudes from the hole 1, so that head 240 need only be moved a small amount in drywall 1. 小的外部直径HD也使得头240 可以容易地隐藏在安装在安装紧固件上的小的物件例如小窗帘杆和小夹板的后面,这样一旦小物件被安装后,锚的头240看不见。 Small external diameter such that the head HD of 240, for example, can be easily hidden behind the small curtain rod and the splint, so that once the small object is installed, the anchor head not visible in the small object 240 mounted on the mounting fastener.

头240的外部直径HD应该足够小以有效防止干墙1鼓包,伹也应该足够大以使头240可以容纳凹槽242,同时在包围凹槽242的近端214仍然具有足够厚的本体212的壁以提供足够的结构完整性来承受扭矩而锚210不会断裂,所述扭矩用于驱动锚210进入干墙1、优选驱动锚210进入干墙1和在其上安装干墙1的支撑部件2,所述支撑部件2可以是例如木质栓。 Outer diameter HD head 240 should be small enough to effectively prevent the bulge drywall 1, Qu also should be large enough to allow the head receiving groove 240 may be 242, while the proximal end 214 surrounding the recess 242 is still sufficiently thick body 212 wall to provide sufficient structural integrity to withstand the torque anchor 210 without breaking the torque for driving the anchor into the drywall 1 210, preferably 210 driving the anchor into the drywall 1 mounted thereon and a support member drywall 1 2, the support member 2 may be, for example wooden peg.

在一个实施例中,头240的外部直径HD等于脊径PC的约50%到约80 %,优选为约75%到约80%。 In one embodiment, the outer diameter of the head HD 240 equal to about 50% to about 80% of the land diameter of PC, preferably from about 75% to about 80%. 在一个实施例中,头直径HD等于脊径PC的约78% 。 In one embodiment, the diameter of the head HD ridge diameter equal to about 78% of PC. 期望地,头240的外部直径HD基本上接近螺纹219的根径PR,可以是根径PR的约1倍到约1.5倍,优选为约1.25倍到约1.45倍。 Desirably, the outer diameter of the head 240 substantially near HD PR thread root diameter 219 may be from about 1 times to about 1.5 times the root diameter of the PR, preferably from about 1.25 times to about 1.45 times. 在图23所示的一个实施例中,头240的外部直径HD是根径PR的约1.38倍。 An embodiment shown in FIG. 23, the head HD outer diameter 240 is approximately 1.38 times the root diameter of the PR.

在一个实施例中,头240的外部直径HD可以介于约0.25英寸到约0.4 英寸,优选介于约0.3英寸到约0.35英寸;在一个实施例中HD为约0.34英寸,同时螺纹219的脊径PC介于约0.4英寸到约0.5英寸,优选介于约0.42 英寸到约0.45英寸;在另一个实施例中HD为约0.43英寸,同时螺纹219的根径PR介于约0.2英寸到约0.3英寸,优选介于约0.225英寸到约0.25英寸;而在另一个实施例中HD为约0.245英寸。 In one embodiment, the outer diameter of the head HD 240 may be between about 0.25 inches to about 0.4 inches, preferably between about 0.3 inches to about 0.35 inches; HD In one embodiment of about 0.34 inches, while the thread ridge 219 PC diameter of between about 0.4 inches to about 0.5 inches, preferably between about 0.42 inches to about 0.45 inches; another embodiment HD embodiment is about 0.43 inches, while PR thread root diameter 219 is between about 0.2 inches to about 0.3 inch, preferably between about 0.225 inches to about 0.25 inches; and in another embodiment of about 0.245 inches HD.

由于头240相对于接合干墙的螺纹219较小,用户可能难以确定锚210 是否被驱入到了一个合适的深度。 Since the head 240 relative to the smaller drywall screw 219 for engagement, the user may be difficult to determine whether or not the anchor 210 is driven into a suitable depth. 当一个大头在干墙1中固定时,通常显示锚已经被驱入到合适深度的现象是用户感觉到扭矩突然增加。 When the bulk of a dry wall 1 is fixed, the normal display to the anchor has been driven into the appropriate user perceives depth phenomenon is a sudden increase in torque. 对于图23所示的实施例,用户无法感觉到这样的扭矩突增,因为头240具有小的外部直径HD。 For the embodiment shown in FIG. 23, the user can not feel such a sudden increase in the torque, because the head 240 has a smaller outer diameter HD. 因此,用户需要通过视觉判定来确定合适的锚210的安装深度,驱动锚210直到头240具有合适的深度以和干墙表面248齐平或刚刚低于干墙表面248。 Accordingly, the user needs to determine the proper depth of the anchor 210 is mounted by visual determination, drive anchor 210 until the head 240 and having a suitable depth to drywall surface 248 flush with or just below drywall surface 248.

参看图25,在一个变换实施例的锚210'中, 一个环形的垫圈或帽246 被安装到头240',这样当锚210'被驱入合适的深度、头240'位于干墙l 中合适的位置时,帽246被从头240'取下。 Referring to Figure 25, the anchor an alternative embodiment 210 'of an annular washer or cap 246 is mounted to the head 240', so that when the anchor 210 'is driven into the proper depth, the head 240' is dry wall l Suitable position, the cap 246 is the head 240 'is removed. 头240'可以包括接收帽246的凹槽241,如图25所示,帽246可以包括和凹槽241吻合的内部唇缘247, 这样帽246可以安全地和头240'保持接合直到有意地拔下帽246。 Head 240 'may include a receiving groove 241 of the cap 246, as shown in FIG, 25 may include a cap 246 inside the recess 241 and the lip 247 of the anastomosis, so that the cap 246 and head 240 can be safely' remains engaged until intentionally pulled under cap 246. 帽246优选地由塑料材料制造,可以通过从一个塑料板切下具有合适尺寸的环形的片、 或模制塑料垫圈得到。 Cap 246 is preferably made of plastic material, it can have a ring of suitable size cut from a sheet of plastic sheet, or molded plastic gasket obtained.

近端部分 A proximal portion

返回图22、 23,近端218与图l一3所示锚10的近端部分18在下面所述方面类似:近端218包括深螺纹219用于接合干墙1,其中螺纹219具有直径为PR的根部226和直径为PC的脊227。 Returning to FIG. 22, 23, a proximal end 218 and a proximal portion in FIG. 3 l anchor 10 is similar to 18 in the following aspects: a proximal end 218 includes threads 219 for engaging the deep drywall 1, wherein the thread has a diameter of 219 PR 226 and the root diameter of the spinal PC 227. 优选地,螺纹219被设置得通过帮助防止干墙面248鼓包来最小化当锚210被驱入时干墙1的可见形变。 Preferably, the thread 219 is set to be 248 by helping to prevent drywall to minimize bulging when the anchor 210 is driven drywall 1-fitting visible deformation.

为了帮助防止鼓包,螺纹219的脊径PC可以略微减小,这样当驱动锚210时螺纹219有较少的表面被推入干墙1。 To help prevent bulging, the thread ridges 219 may be slightly reduced diameter PC, so that when the drive screw 210 when the anchor 219 is pushed into the surface there are fewer drywall 1. 在图23可以最好地表示的一个实施例中,通过在螺纹219的脊227形成一个基本上平面区域234,而不是如图l一3所述的实施例那样形成实质上成角度的脊27。 In one embodiment, the thread ridge 219 is formed as a substantially planar region 227 is formed 234, rather than a 3 l of the embodiment shown in FIG substantially angled ridges 27 in FIG. 23 may represent the best . 所述基本上平面区域234使脊227稍向里变化,这样整个的脊径PC被减小。 So that the substantially planar region 234 in the ridge 227 slightly changes, so that the entire PC ridge diameter is reduced. 与没有区域234 的情形相比,脊径PC可以被减小约2X到约10%,优选约3%到约7%,在一个实施例中优选为5%。 Compared with the case without the region 234, PC ridge diameter can be reduced from about 2X to about 10%, preferably from about 3% to about 7%, in one embodiment the preferred embodiment is 5%.

在一个实施例中,螺纹219是一般为螺旋状的螺纹219,区域234是一般为螺旋状的带,所述带沿螺纹219的脊227延伸。 In one embodiment, the thread 219 is a generally helical thread 219, region 234 is generally spiral band, with the ridge extending along the thread 219 227. 优选地,区域234 —般平行于轴206。 Preferably, the region 234 - as parallel to the axis 206. 具有区域234的螺纹219可以通过模制或铸造具有区域234 的锚210得到,或者可以先形成类似于锚10的螺纹19的螺纹219,然后通过锉或其他方式整平螺纹219的脊227。 219 having a threaded region 234 may have a molded or cast by an anchor region 234 to give 210, or may be formed similarly to the anchor screw thread 19 10 219, and by filing or otherwise flattened thread ridge 219 227.
