For locking the door lock, a key is used for pushing the lock plunger device to move, and the lock plunger on the lock plunger device is clamped on a predetermined hole on a doorframe. While the lock plunger is pushed, the lock plunger can drive the linking part of the clamping device to move, and the clamping part which extends out is clamped in the upper and lower through holes of one side of the cover body.
Description
The utility model provides a kind of anti-picking device of door lock, and the general door lock of particularly a kind of cooperation uses, and makes door have dual effect of locking, to reach the purpose of pick-proof.
All be provided with lockset on the general door-plate, to reach antitheft effect, and door lock in the past, as shown in Figure 1, include lock head device 1 and locking bolt device 10, lock head device 1 can promote not have pin device 10 by key, make the locking bolt 11 on the locking bolt device 10 protrude lockset, and be stuck on the doorframe in the default hole, reaching the effect of locking, and the detailed construction of this kind lockset is identical with general lockset.Yet, though general at present door is gone up and all is provided with lockset, to reach antitheft effect, but, its only the locking bolt 11 on the locking bolt device 10 convexedly stretch in the hole of doorframe, and can't really reach antitheft purpose, when worthless fellow's desire is destroyed lockset, an available powerful tools is inserted between the space of door-plate and doorframe, impose the power of prying open again, can easily the locking bolt on the door lock be destroyed, it can't be gone again be stuck on the doorframe, and door is opened, and it is also quite quick when it destroys, convenient, so the lockset on the at present general door-plate only can tentatively reach the purpose of locking, and can't effectively reach antitheft purpose.
Main purpose of the present utility model is to provide a kind of door lock, and it has the effect of dual pick-proof, to reach the purpose that is difficult for prying open.
Another purpose of the present utility model is to provide a kind of door lock, and it has the effect with the lockset interlock, to reach the purpose of locking simultaneously.
For reaching above-mentioned purpose, the anti-picking device of the utility model door lock is characterized in that it is provided with holder, and holder and door lock covers on the body with being arranged at, and when promoting the locking bolt device when the unlatching door lock, can drive holder simultaneously to move; Holder is equipped on the default hole of doorframe, to reach dual purpose of locking.
Holder is provided with linkage part and fastening part, linkage part one end is fixed on the locking bolt device of door lock, the other end is fixed on the fastening part, when making the locking bolt device of door lock move, can drive fastening part by linkage part moves, fastening part is protruded out, when desiring to lock door lock, available key promotes the locking bolt device and moves, locking bolt on the locking bolt device is stuck in the default hole of doorframe, and the locking bolt device is pushed simultaneously, the linkage part that drives holder moves, its fastening part is protruded out and be stuck on the doorframe in the default hole, to reach dual closure effect.
Be elaborated below by most preferred embodiment and accompanying drawing anti-picking device to door lock of the present utility model, in the accompanying drawing:
Fig. 1 is the sectional view of door lock arrangement in the past.
Fig. 2 is the anti-picking device exploded view of the utility model door lock.
Fig. 3 is the constitutional diagram of the anti-picking device of the utility model door lock.
Fig. 4 is the schematic diagram of the anti-picking device of the utility model door lock.
Fig. 5 is the enforcement figure of the anti-picking device of the utility model door lock.
Fig. 6 is another embodiment of the anti-picking device of the utility model door lock.
Shown in Fig. 2,3, the anti-picking device of the utility model door lock includes and covers body 2 and holder 3.
Holder 3 is provided with linkage part 30 and fastening part 31, linkage part 30 1 ends are fixed on the locking bolt device 40 of door lock 4, the other end then is fixed on the fastening part 31, when making the locking bolt device 40 of door lock 4 move, can drive fastening part 31 by linkage part 30 moves, fastening part 31 is protruded out cover two perforation 24 up and down of body 2 one sides, the linkage part 30 of holder 3 is provided with master connecting-rod 32 in the present embodiment, two slave connecting rods 33 and both sides connecting rod 34, master connecting-rod 32 1 ends are fixed on the locking bolt device 40 of door lock 4, the other end then is fixed on two slave connecting rods, 33 1 ends, two slave connecting rods, 33 other ends then are articulated on the both sides connecting rod 34, connecting rod 34 1 ends in both sides articulate mutually, and be fixed on the front cover body 20,31 of fastening parts are provided with the kelly 35 and the collar 36, side connecting rod 34 other ends then are fixed on the kelly 35, and kelly 35 then is sheathed on the collar 36.
As shown in Figure 4, when the master connecting-rod 32 that promotes holder 3 moves down when driving slave connecting rod 33 and drawing toward door lock 4 directions, the mobile end of kelly 35 that then side connecting rod 34 is fixed with of slave connecting rod 33 is toward a side shifting, and owing to connecting rod 34 1 ends in both sides are fixed on the front cover body 20, therefore, the other end of side connecting rod 34 can obtain bigger displacement, and toward the moving kelly 35 of a thruster, and kelly 35 protrudes out the perforation 24 of covering body 2.
As shown in Figure 5, the utility model can be used on the iron gate, door lock on the door 4 is fixed in the front cover body 20, and master connecting-rod 32 1 ends of the linkage part 30 of holder 3 are fixed on the locking bolt device 40 of door lock 4, when starting door lock 4 with key, the locking bolt 41 that makes locking bolt device 40 is stretched out the perforation 23 of covering body 2, and spur the linkage part 30 of holder 3 simultaneously, fastening part 31 is also moved toward the direction that the locking bolt 41 of door lock 4 moves, make the kelly of fastening part 31 protrude out the perforation 24 of covering body 2, therefore, when desire is locked door 5, the locking bolt 40 of door lock 4 and the kelly 35 of holder 3 are stuck in the hole 60 default on the doorframe 6 simultaneously, to reach the dual purpose of locking in chamber, and when the worthless fellow destroys the locking bolt 41 of door lock 4 between door 5 and doorframe 6, also do not cause door to be pried open, thereby can reach preferable anti-theft effect.
