Description

翻爆式紧固螺丝及其防滑膨胀螺套
技术领域
本发明涉及一种紧固螺丝及其部件，尤其涉及一种翻爆式螺丝及其膨胀螺套的结构改进，本发明的翻爆式紧固螺丝适用于将物件固定在天花、墙面或地上。
背景技术
现有技术中，为了在天花、墙面或地上固定物件，需要用到膨胀螺丝，常用的膨胀螺丝有顶爆螺丝和拉爆螺丝等形式。其中，普通的拉爆螺丝，如公告号为CN201190716Y的中国实用新型专利，如图1所示，由相互旋接的螺杆91和外套92组成，所述外套92上部均分有多块裂片93，螺杆91中部设有锥形面，在两者旋接的过程中，通过螺杆91的锥形面可将外套92上的裂片93撑开以此将螺杆91固定。但是这种拉爆螺丝的外套92的表面是光滑表面，在与螺杆91旋接的过程中容易发生打滑现象并随着螺杆91一起转动，很难达到拉爆效果，由此令螺丝无法紧固，甚至外套92无法膨胀打开造成无法使用，因此也 会存在安全隐患。而如图2所示的顶爆螺丝，其安装难度大，其膨胀套打开相当困难，如遇到密度高或标号高的楼板或地板，特别是遇到石材，就基本无法膨胀打开，同样存在着安全隐患。
发明内容
本发明要解决的技术问题是提供一种能防止膨胀螺套与安装孔之间打滑由此可保证较好紧固效果的翻爆式螺丝及其防滑膨胀螺套。
本发明解决上述技术问题所采用的技术方案是：
一种防滑膨胀螺套，包括圆筒状的壁部，在所述圆筒状的壁部的一端开设有多条延伸到中部的轴向切断槽，由此形成所述防滑膨胀螺套多个易于向外张开的叶片单元，所述防滑膨胀螺套的内孔壁设有可与螺栓旋配的内螺纹，其外壁设置有防滑的粗糙表面。
所述防滑膨胀螺套外壁的防滑粗糙表面为分布在所述外壁面的多条轴向凸条或均匀分布在所述外壁面的凸点或凸块。
本发明的翻爆式紧固螺丝包括：主体螺丝以及与该主体螺丝的螺杆旋配的防滑膨胀螺套，所述主体螺丝螺杆的中部设置有用于推顶所述防滑膨胀螺套叶片单元向外张开的锥形面，所述防滑膨胀螺套的外壁设置有防滑的粗糙表面。
所述锥形面是一体成型于所述主体螺丝的螺杆中部的。
或者，所述锥形面设置在一独立的限位膨胀头的上端面，该限位膨胀头穿套于所述主体螺丝的螺杆并移到适当的位置后通过压紧、打凹点或打销钉固定在所述主体螺丝的螺杆上。
所述防滑膨胀螺套外壁的防滑粗糙表面为分布在所述外壁面的多条轴向凸条或均匀分布在所述外壁面的凸点或凸块。
所述主体螺丝顶部设有一扩大的螺帽，该螺帽周边设有凹凸纹，其底面设有一字形、十字形或多边形凹槽。
所述主体螺丝下部为安装后外露的扁平状的接驳头，该接驳头的侧壁具有至少一个平面，该接驳头与主体螺丝中部交接处沿周边设有限制所述主体螺丝进入安装孔深度的限位凸沿，安装后露出的接驳头可焊接其它物体。
本发明的翻爆式紧固螺丝还可以包括天花组合螺丝，所述主体螺丝顶部设有带内螺纹孔的螺帽，所述天花组合螺丝包括螺纹杆、套在该螺纹杆上的承托片以及旋接于所述螺纹杆底部并支撑所述承托片的螺帽；所述螺纹杆与主体螺丝顶部螺帽的内螺纹孔旋接。
或者，可以包括一挂件，所述主体螺丝顶部固设有带内螺纹孔的螺帽，所述挂件顶部设有与所述主体螺丝顶部螺帽内螺纹孔配合的外螺纹。
同现有技术相比较，本发明的翻爆式紧固螺丝及其防滑膨胀螺套具有如下创新技术效果：由于防滑膨胀螺套具有可增加摩擦力的外表面，因此在与主体螺丝旋接时，防滑膨胀螺套与安装孔位之间不容易打滑，从而可大大提高安装效率，且可保证防滑膨胀螺套能充分张开，确保其可靠的紧固作用；主体螺丝的锥形面还可设置在独立的限位膨胀头端面，即使主体螺丝的直径较大也无须使用大型设备来加工，由此可大大降低加工成本；在不需要使用时可将主体螺丝拆卸，不但能保持安装场地的平整美观，而且主体螺丝能够循环使用，更加环保。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明做进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图4和图5所示，本发明的防滑膨胀螺套1呈圆筒状，其周边侧壁均匀开设有多条从端部贯穿至中部的轴向切断槽11由此形成多个叶片，所述防滑膨胀螺套1上部设有内螺纹，本发明的特别之处在于：所述防滑膨胀螺套1的侧壁外表面为防滑粗糙表面可以增加摩擦力，所述防滑粗糙表面可以是轴向凸条、凸点或凸块等形状的凸起12，数量、尺寸不限，并沿周向均匀布设于防滑膨胀螺套1的侧壁外表面，本实施例中采用竖向的凸条并设置在每块叶片的中间。采用上述结构后，防滑膨胀螺套1与安装孔壁之间的摩擦力增大，能有效防止防滑膨胀螺套1在安装的过程中发生打滑的现象，从而大大提高了安装效率，确保可靠的紧固效果。
如图11所示，本发明的翻爆式紧固螺丝包括主体螺丝2以及与该主体螺丝2的螺杆旋配的防滑膨胀螺套1。所述防滑膨胀螺套1的结构同上，所述主体螺丝2尾部设有可与防滑膨胀螺套1上部内螺纹配合的外螺纹24，中部设有由上至下直径逐渐增大的锥形面21，防滑膨胀螺套1底部的内径介于所述锥形面21的最小直径和最大直径之间，主体螺丝2头部22的外形可以是六角形、四方形、球形、十字形等，其尺寸和形状不限。这样，当扭动主体螺丝2与防滑膨胀螺套1旋接时，防滑膨胀螺套1侧壁外表面设置的凸起12与安装孔壁之间的摩擦力大大增加，可有效防止防滑膨胀螺套1打滑转动，使之完全不会跟着主体螺丝2一起转动，与此同时，防滑膨胀螺套1由于与锥形面21相抵使得其下部的叶片向外膨胀张开，形成反向力学的作用，当螺丝扭得越紧，其反向力就越大，螺丝承受的吊力、拉力就越稳。
本发明的防滑膨胀螺套可与多种形式的主体螺丝2及其他配件组合使用，如天花、灯饰、焊接、挂件等紧固螺丝，下面用五个实施例加以描述：
实施例一、如图3所示，所述主体螺丝2包括螺杆本体23和限位膨胀头25两个独立的部件，所述锥形面21设置在限位膨胀头25的上部，该限位膨胀头25套接在螺杆本体23上并可上下移动至合适的位置以适应不同深度的安装孔，移至合适位置后可通过压紧、打凹点20或打销钉等方法将限位膨胀头25固定在螺杆本体23上，即可旋动螺杆本体23，使防滑膨胀螺套1在限位膨胀头25的锥形面21的压力下膨胀打开。所述螺杆本体23下部既可以是带外螺纹的螺纹杆，也可以是侧壁光滑的杆件，当带有带外螺纹时，还可以用于旋接如实施例一中所述的承托片32以及螺帽33，特别适用于吊装天花、灯饰或空调等。
实施例二、如图6所示，所述主体螺丝2为吊灯饰螺丝，其尾部设有外螺纹与防滑膨胀螺套1配合，其中部设有锥形面21，其顶部设有一扩大的螺帽26，该螺帽26周边设有凹凸纹，其顶面设有一字形、十字形或多边形凹槽27，可供扭动主体螺丝2。安装时，将防滑膨胀螺套1打入安装孔内，转动主体螺丝2，由于防滑膨胀螺套1外侧壁凸块12的定位防打滑作用，防滑膨胀螺套1在锥形面21的压力下膨胀打开，主体螺丝2即可以安装灯饰或其它物件。
实施例三、如图7所示，所述主体螺丝2为焊接接驳螺丝，其尾部设有外螺纹与防滑膨胀螺套1配合，其中部设有锥形面21，其顶部为扁平状的接驳头28，该接驳头28的侧壁具有至少一个平面用于焊接其他物件，本实施例中，如图8所示，该接驳头28的横截面大致呈方形。在旋动主体螺丝2使防滑膨胀螺套1打开固定在安装孔后，可通过焊接将其他物件焊接固定在接驳头28上。此外，该接驳头28与主体螺丝2中部交接处沿周边可设有一 限制主体螺丝2打入安装孔深度的限位凸沿29，安装后露出的接驳头可焊接其它物体。
实施例四、如图9所示，所述翻爆式紧固螺丝包括: 防滑膨胀螺套1、主体螺丝2以及天花组合螺丝3。该天花组合螺丝3又包括：螺纹杆31、套在该螺纹杆31上的承托片32以及旋接于所述螺纹杆31底部并支撑所述承托片32的螺帽33。所述主体螺丝2顶部设有带内螺纹孔的螺帽22可与天花组合螺丝3的螺纹杆31螺纹配合，由此可用于吊装天花、灯饰或空调等。
实施例五、如图10所示，所述翻爆式紧固螺丝包括：防滑膨胀螺套1、主体螺丝2以及挂件5，该挂件5可以是挂钩或挂环状，其顶部设有外螺纹51。所述主体螺丝2底部固设有带内螺纹孔的螺帽22可与挂件5顶部的外螺纹51螺纹配合，由此可用于吊挂物件。
需要说明的是，上述实施例二至五中的锥形面21均可以象实施例一的一样，设置在一个独立的限位膨胀头25端面，由此可以根据安装孔的深度来调节锥形面21的位置再固定，而且采用这种独立限位膨胀头25的结构，即使主体螺丝的直径较大，也无需像现有产品一样必须采用大型的设备加工，由此可大大降低了接驳螺丝的加工成本。
本发明的翻爆式紧固螺丝及其防滑膨胀螺套完全解决了现有技术中传统拉爆螺丝及顶爆螺丝的安装难题，可配合不同的配件使用，用途广泛、安装简便快捷且安全稳固。在不需要使用时，还可以将主体螺丝拆除，保持安装场地平整，拆除下来的主体螺丝还可重复使用，非常节约及环保。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
本发明提供一种翻爆式紧固螺丝及其防滑膨胀螺套，由于防滑膨胀螺套具有可增加摩擦力的外表面，因此在与主体螺丝旋接时，防滑膨胀螺套与安装孔位之间不容易打滑，从而可大大提高安装效率，且可保证防滑膨胀螺套能充分张开，确保其可靠的紧固作用；主体螺丝的锥形面还可设置在独立的限位膨胀头端面，即使主体螺丝的直径较大也无须使用大型设备来加工，由此可大大降低加工成本；在不需要使用时可将主体螺丝拆卸，不但能保持安装场地的平整美观，而且主体螺丝能够循环使用，更加环保，具有工业实用性。
