Description

A kind of lockable mechanism is set to the anti-theft lock in front of shifting part

Technical field

The utility model relates to field of lockset, specifically a kind of lockable mechanism is set to the theftproof lock in front of shifting part Core.

Background technique

There are many popular illegal unlock method in the world now: hit spoon (English is Bump Lock) is unlocked, drill bit is unlocked, Pull lock core is unlocked, picklock is unlocked etc..And anti-illegal unlock technology is also with there are many kinds: prizing-proof lock core, anti-drilling Lock core is prevented pulling out lock core, anti-twistlock core (anti-snap), anti-bump key lock core (anti-bump) etc..

Currently, some robbers also start to implement theft using the means that violence is unlocked, they are entangled with special socket bar Outer side of door one lock core head is perhaps then firmly pulled up and down with the lock core head that locking pliers clamps outer side of door one or a left side The right side is firmly pulled, and is made the middle part fracture that lock core is weaker and is destroyed lock core structure, since the components in lock core can be mutually detached from, The lock core of fracture can be extracted easily and open lock by robber.

Exploitation devises and a series of prevents tightened core, such as patent No. successively since the second half year in 2013:

201320826547.8、 201320768059.6、 201320768384.2、 201320662229.2、 201420206310.4 waiting；Their major measure is by preventing from locking to being reinforced in the middle part of lock core body, anti-stubborn slot being arranged Core is screwed disconnected from middle part.Subsequent and exploitation devises a series of anti-theft locks with lockable mechanism, such as patent No.: 201420559153.5,201420754186.5,201420586337.0,201820817950.7 etc., wherein the patent No. It 201420754186.5, is all that lockable mechanism is set in lock core in 201420586337.0,201820817950.7 Portion, more rearward, and 201420754186.5 lockable mechanism is set to the front of shifting part, still, lockable mechanism for lock position Not with it is interior turn part constitute cooperation and form locking, these above-mentioned lock cores can play antitheft effect, but still have and further change Into space, to reach stronger anti-theft effect.

Summary of the invention

The purpose of the utility model is to make up above-mentioned deficiency, and Xiang Shehui open structure is reasonable, easy to make, cost of manufacture Low, a kind of safe and reliable lockable mechanism is set to the anti-theft lock in front of shifting part.

The utility model is described in further detail with reference to the accompanying drawing:

As shown in Figures 1 to 8,

A kind of lockable mechanism is set to the anti-theft lock in front of shifting part, including lock core inner core 1, lock core body 2, lock core inner core With the rows of marble hole of ordered series of numbers being arranged with being communicated in lock core body, lower pellet 31 in lock core in in-core marble hole, lock core body Closure door pellet 32 at the top of marble hole, the spring 33 sealed up a door under pellet are upper in lock core body marble hole when lock core opening state Pellet 34 opens the shifting part 4 of lock tongue, be connected to driven on lock core inner core shifting part 4 in turn part 5, on the lock core body 2 The anti-stubborn slot 21 vertically opened up, it is described in turn to push up spring after being provided between the rear end of part 5 and the lock core inner core 1 on the inside of door 5a is provided with lockable mechanism in the front of shifting part 4 on the lock core body 2, which includes to be arranged from top to bottom Closure door screw 61, locking spring 62, upper bayonet lock 63 and lower bayonet lock 64, when lock core is complete, the upper bayonet lock 63 be located at lock The top of in-core core 1, the top of the lower bayonet lock 64 are located in the through-hole 11 of the lock core inner core 1 of outer side of door, and its underpart is located at Inside turn in the locking through hole 5b of part 5, the lower end of lower bayonet lock 64 offsets with the interior inner top part 7 turned in part 5, the inner top part 7 are provided with lock groove 7a at the rear of locking through hole 5b, the inner top part 7 and interior turn to be provided with interior top spring between part 5 74。

The inner top part 7, which is placed through in described, turns the center of part 5, it is described in turn part 5 by turning part list in outer side of door Turn part monomer 52 on the inside of body 51 and door to be composed, the both ends of the inner top part 7 are correspondingly arranged on the first extension diameter section 71 With the second extension diameter section 72, connecting shaft 73, the interior top spring 74 are provided between the first extension diameter section 71 and the second extension diameter section 72 It is sheathed on outside connecting shaft 73.

The locking through hole 5b is linear type structure, and locking through hole 5b uses linear type structure, is to turn part in making It does not influence normal function when moving forward and backward and guarantees in the case where having broken in front, lower bayonet lock can be entered accurately in card slot Face is gone, and so that the assembly of lock core is become convenient, be can be improved the assembly efficiency of lock core.

Shifting part slot 1b is offered on the outside of the card collar groove 1a of the lock core inner core 1, the inner circumferential of the shifting part 4 is set It is equipped with convex block 4a compatible with the shifting part slot 1b, the shifting part slot 1b and the convex block 4a clamping engagement.

The convex block 4a is symmetrically disposed on 4 inner circumferential of shifting part and longitudinal axis in 30 ° of angular positions.

Working principle:

When lock core is installed, lockable mechanism is installed on outer side of door, when lock core is complete, upper bayonet lock 63 is located at lock core inner core 1 Top do not influence the rotation of lock core inner core 1 when key unlocking, and lower bayonet lock 64 is located at lock core inner core 1 and interior to turn part 5 same Sample will not influence the rotation of lock core inner core 1, and lock core can be normally-open.At this moment, interior since there is obstruction in the front of inner top part 7 Lock groove 7a on top part 7 is staggered with lower bayonet lock 64.

Once encountering violence unlocking, when lock core is twisted into two parts from anti-stubborn slot 21, the front of inner top part 7 loses resistance, Inner top part 7 will act on lower Forward by top spring 74 inside, when the lock groove 7a on inner top part 7 is moved to lower 64 lower section of bayonet lock When, lower bayonet lock 64 is fallen in lock groove 7a；Upper bayonet lock 63 is stuck in lock core inner core 1 and lock core body 2 as lower bayonet lock 64 falls Between both make to form one.In this way, lock core body 2, lock core inner core 1, the interior part 5 that turns just is made to form an entirety, and interior turn part 5 Cooperation is connect with shifting part 4, lock core remainder forms reliable entirety, and lock core can not be opened.When lock core front is broken When, the rear spring 5a that pushes up can be avoided the interior normal work for turning 5 entirety of part and moving backward and influence lockable mechanism.

Furtherly, the convex block 4a and shifting part slot 1b on lock core inner core 1 of 4 inner circumferential of shifting part setting fastens, into one Step improves anti-theft performance, ensure that the overall security of entire lock core.
