Description

锁止机构的锁止孔设于内转件上的防拧防盗锁芯The locking hole of the locking mechanism is set on the anti-twist and anti-theft lock cylinder on the inner turning piece

技术领域 technical field

本实用新型涉及锁具领域,具体地说是锁止机构的锁止孔设于内转件上的防拧防盗锁芯。 The utility model relates to the field of locks, in particular to an anti-twisting and anti-theft lock cylinder in which a locking hole of a locking mechanism is arranged on an inner rotating piece.

背景技术 Background technique

现今国际上流行的非法开锁方法很多:撞匙(英语为 Bump Lock)开锁、钻头开锁、拔拉锁芯开锁、撬锁工具开锁等。而防非法开锁技术也随着出现了很多种:防撬锁芯、 防钻锁芯、防拔锁芯、防扭锁芯(anti-snap)、防撞匙锁芯(anti-bump)等。 There are many illegal unlocking methods that are popular in the world today: bump key (Bump Lock in English) unlocking, drill bit unlocking, pulling the lock cylinder to unlock, lock picking tools to unlock, etc. And anti-illegal unlocking technology has also appeared many kinds along with it: anti-picking lock cylinder, anti-drilling lock cylinder, anti-pull lock cylinder, anti-twist lock cylinder (anti-snap), anti-collision key lock cylinder (anti-bump) etc.

目前,有的盗贼也开始采用暴力开锁的手段实施盗窃,他们用特制的套筒杆套住门外侧一头的锁芯头部或者用大力钳夹住门外侧一头的锁芯头部,然后用力上下扳或者左右用力扳,使锁芯较薄弱的中部断裂而破坏锁芯结构,由于锁芯中的零部件相互可以脱离,盗贼可以轻易将断裂的锁芯拔出而将锁打开。 At present, some thieves have also begun to use the means of violent unlocking to carry out the theft. They use a special sleeve rod to cover the head of the lock cylinder on the outside of the door or clamp the head of the lock cylinder on the outside of the door with pliers, and then forcefully go up and down. Pull or pull left and right to make the weaker middle part of the lock cylinder break and destroy the structure of the lock cylinder. Since the parts in the lock cylinder can be separated from each other, thieves can easily pull out the broken lock cylinder to open the lock.

现有的锁芯采用在锁芯体上设置防拧槽来防止这种暴力开锁方式,防拧槽竖向设置于锁芯体上,由于防拧槽的设置,当盗贼暴力开锁时,锁芯体会从防拧槽处断裂,而防拧槽的后部扔保持完好,从而避免了锁因锁芯体的中部被拧断而被打开。但是,当锁芯体从防拧槽处断裂后,盗贼只需要将装配在一起的拨动件、内转件、锁芯内芯一一卸下,便可以将锁打开,因此仅仅设置防拧槽来防止暴力开锁是远远不够的。 The existing lock cylinder uses an anti-twist groove on the lock cylinder body to prevent this violent unlocking method. The anti-twist groove is vertically arranged on the lock cylinder body. Due to the setting of the anti-twist groove, when a thief violently unlocks the lock, the lock cylinder The experience breaks from the anti-twist groove, while the rear part of the anti-twist groove remains intact, thereby preventing the lock from being opened due to the middle part of the lock cylinder being twisted off. However, when the lock cylinder breaks from the anti-twist groove, the thief only needs to remove the assembled toggle piece, inner turning piece, and lock cylinder inner core one by one to open the lock, so only the anti-twist Slots are not enough to prevent brute force unlocking.

如图1至图6所示, As shown in Figure 1 to Figure 6,

一种锁止机构的锁止孔设于内转件上的防拧防盗锁芯,包括锁芯内芯1,锁芯体6,锁芯内芯和锁芯体中相通地设置着的数列成排的弹子孔,锁芯内芯内弹子孔中的下弹子2,锁芯体弹子孔顶部的封门弹子5,封门弹子下的弹簧4,锁芯打开状态时的锁芯体弹子孔中的上弹子3,开启锁舌的拨动件12,连接在锁芯内芯上带动拨动件12的内转件11,竖向设置于锁芯体6上的防拧槽8;所述的锁芯中部设置有锁止机构,该锁止机构包括:竖向开设于拨动件12上的空腔91,从下至上依次置于所述空腔91内的锁止销92、锁止弹簧93和紧定螺丝94;该锁止机构还包括:门内侧的锁芯内芯1位于所述空腔91的正下方开设有通孔1a,所述的通孔1a内设置有钢珠95,该钢珠95的下端与内转件11相抵,所述的内转件11上的内侧上方开设有深度大于钢珠95直径的锁止孔11a,该锁止孔11a位于所述通孔1a的内侧,所述的内转件11的内侧端经活动销96与一限位弹簧97相配合。 An anti-twisting and anti-theft lock cylinder with a locking hole of a locking mechanism arranged on an inner rotating piece, comprising a lock cylinder inner core 1, a lock core body 6, and a series of arrays arranged in communication between the lock core inner core and the lock core body The pinholes in the row, the lower pinhole 2 in the pinhole in the inner core of the lock cylinder, the door-sealing pinhole 5 on the top of the pinhole of the lock cylinder body, the spring 4 under the door-sealing pinhole, the upper pinhole in the pinhole of the lock cylinder body when the lock cylinder is open. The pin 3, the toggle piece 12 for opening the lock bolt, is connected to the inner turning piece 11 that drives the toggle piece 12 on the inner core of the lock cylinder, and is vertically arranged on the anti-twist groove 8 on the lock cylinder body 6; the lock cylinder The middle part is provided with a locking mechanism, which includes: a cavity 91 vertically opened on the toggle member 12, a locking pin 92, a locking spring 93 and a locking spring 93 placed in the cavity 91 from bottom to top. Set screws 94; the locking mechanism also includes: the inner core 1 of the lock cylinder on the inner side of the door is located directly below the cavity 91 and has a through hole 1a, and a steel ball 95 is arranged in the through hole 1a, and the steel ball 95 The lower end of the inner rotating part 11 is against the inner rotating part 11. A locking hole 11a with a depth greater than the diameter of the steel ball 95 is opened on the inner side of the inner rotating part 11. The locking hole 11a is located on the inner side of the through hole 1a. The inner side end of the inner rotating part 11 cooperates with a limit spring 97 via a movable pin 96 .

所述的防拧槽8竖向开设于所述锁芯体6的上部,所述的防拧槽8的底边呈一侧高、一侧低的倾斜结构。 The anti-twist groove 8 is vertically opened on the upper part of the lock core body 6, and the bottom edge of the anti-twist groove 8 has an inclined structure with one side high and one side low.

所述的门内侧的锁芯内芯1上横向开设一孔1b,所述的活动销96和限位弹簧97置于该孔1b内。 A hole 1b is horizontally opened on the inner core 1 of the lock cylinder inside the door, and the movable pin 96 and the limit spring 97 are placed in the hole 1b.

所述的内转件11由第一内转件单体11b和第二内转件单体11c拼接而成。 The inner turning member 11 is spliced by a first inner turning member unit 11b and a second inner turning unit unit 11c.

工作原理: working principle:

在锁芯完好时,紧定螺丝94固定于空腔91的开口处,锁止弹簧93的上部与紧定螺丝94的下部相抵,锁止弹簧93的下部与锁止销92的上部相抵,锁止销92的下部与位于门内侧锁芯内芯的通孔1a内的钢珠95的上部相抵,钢珠95的下部与内转件11相抵.由于钢珠92表面光滑,钢珠92的存在并不会影响锁芯内芯1的正常转动,从而保证锁芯能够正常使用。 When the lock cylinder is in good condition, the set screw 94 is fixed at the opening of the cavity 91, the upper part of the locking spring 93 is offset against the lower part of the set screw 94, and the lower part of the locking spring 93 is offset against the upper part of the locking pin 92, and the locking The lower part of the stop pin 92 is offset against the upper part of the steel ball 95 located in the through hole 1a of the lock cylinder inner core inside the door, and the lower part of the steel ball 95 is offset against the inner turning part 11. Since the surface of the steel ball 92 is smooth, the existence of the steel ball 92 will not affect The normal rotation of the inner core 1 of the lock cylinder ensures that the lock cylinder can be used normally.

当盗贼用大力钳暴力开锁时,锁芯体6首先在防拧槽8处断裂,如图5所示,断裂后的锁芯体6门外侧部分可以从门外侧取出,第一内转件单体11b一起被取出,而防拧槽8后部的锁芯体6保持完好。由于锁芯体6门外侧部分断裂,第二内转件单体11c失去了锁芯体6门外侧部分的限制,限位弹簧96的弹力作用于活动销96,弹力经活动销96的传递作用于第二内转件单体11c上,将第二内转件单体11c向门外侧推,直到锁止孔11a移动至通孔1a下方,通孔1a内的钢珠95掉入锁止孔11a内,同时锁止销92随之下落,锁止销92的下部也进入锁止孔11a内。此时,锁止销92的上部扔位于拨动件12的空腔91内,其中部位于门内侧的锁芯内芯1的通孔1a内,其下部位于锁止孔11a内,将拨动件12、门内侧的锁芯内芯1、内转件11三者卡住而使三者形成整体,从而使锁无法被打开,保证了锁芯的安全性。 When a thief violently unlocks the lock with pliers, the lock core body 6 breaks at the anti-twist groove 8 at first. The body 11b is taken out together, and the lock core body 6 at the rear of the anti-twist groove 8 remains intact. Due to the breakage of the outer part of the lock core body 6, the second internal transfer unit 11c loses the restriction of the outer part of the lock core body 6 doors, the elastic force of the limit spring 96 acts on the movable pin 96, and the elastic force is transmitted through the movable pin 96 On the second inner turning unit 11c, push the second inner turning unit 11c to the outside of the door until the locking hole 11a moves below the through hole 1a, and the steel ball 95 in the through hole 1a falls into the locking hole 11a At the same time, the locking pin 92 falls, and the lower part of the locking pin 92 also enters the locking hole 11a. At this time, the upper part of the locking pin 92 is located in the cavity 91 of the toggle member 12, the middle part is located in the through hole 1a of the lock cylinder inner core 1 inside the door, and its lower part is located in the locking hole 11a. Part 12, the lock core inner core 1 on the inside of the door, and the inner transfer part 11 are blocked and the three are formed as a whole, so that the lock cannot be opened, ensuring the safety of the lock core.
