Abstract
The utility model discloses a two direction bolt type anti-theft lock. The utility model adopts a guide plate and a link mechanism, and the utility model is added with a clamping plate which is used for locking a door lock. The cylindrical pin of a rotary plate drives the guide plate to do motion, so the link mechanism is driven to do motion; the bidirectional motion of a lock tongue is realized by a sliding plate and a connecting plate; thereby, the utility model can be opened or closed. Lock end protecting bodies are arranged at the both ends of the lock body of shell shape, so the integral fastness of the utility model is enhanced. The utility model has the advantages of anti-prying, anti-smashing, anti-drilling and anti-collision; so the anti-theft performance of the utility model is enhanced.
Description
The utility model relates to a kind of door lock, particularly a kind of two-way door latch type theftproof lock.
Popular in the market is various single, double to door lock, and what majority adopted is gear, rack-and-pinion structure, and the dead bolt of this lock is shorter, and anti-group of property is relatively poor; The lock box volume is little, installs insecurely on door, and whole theftproof is poor, pick-proof, anti-drilling, anti-ly pound, function such as anti-collision is not good enough.Relevant by retrieval document still finds no and the same or analogous record of the utility model.
The purpose of this utility model just provides a kind of employing guide plate, linkage, the two-way door latch type theftproof lock that theftproof is strong.
Technical solution of the present utility model is:
Be fixed with linkage on the hull shape lock body, an end of linkage links to each other with guide plate, and the other end of guide plate links to each other with dead bolt by connecting plate, and guide plate top is provided with clamp, and adopts steady pin to connect; The other end of linkage is connected with slide plate, and an end of connecting rod is fixed on the slide plate, and the other end links to each other with dead bolt by connecting plate.The two ends of hull shape lock body are fixed with lock end watch box, and offering on the watch box can be by the hole of dead bolt.
The utility model has adopted guide plate and linkage, simple in structure, processing, easy to maintenance, owing to adopted hull shape lock body and lock end watch box structure, improved theftproof performance significantly, strengthened door body intensity, even destroyed door hinge or bore bad lock core and still can not open door, have anti-ly search, pick-proof, anti-drilling, anti-pounding and performance such as anti-collision.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is the structural representation after the utility model is opened lock box;
Fig. 2 is that A-A of the present utility model is to the structure sectional view.
With reference to accompanying drawing, the utility model comprises main hull shape lock body 1, lock box 2 and dead bolt 9, be fixed with linkage 5 (present embodiment is a three-link mechanism) on the hull shape lock body 1, one end of linkage 5 is connected with slide plate 6, slide plate 6 offers chute 15, is provided with the pin that is fixed on the hull shape lock body 1 in the groove; Be fixed with connecting rod 7 on the slide plate 6, connecting rod 7 other ends link to each other with connecting plate 10, and an end of dead bolt 9 just is fixed on the connecting plate 10.The other end of linkage 5 links to each other with guide plate 4, and the other end of guide plate 4 links to each other with dead bolt 9 by connecting plate 10, and guide plate 4 is provided with clamp 3; The two ends of hull shape lock body 1 are fixed with lock end watch box 8, and offering on the watch box can be by the hole of dead bolt 9.
Be connected to riveted joint between linkage, guide plate, slide plate and the connecting plate.
One end of clamp 3 is fixed on the hull shape lock body 1 by steady pin 33, and steady pin 33 is provided with the torsion spring 14 to 3 reset responses of clamp.Offer draw-in groove 31 on the clamp 3, be provided with stop pin 32; Offer gathering sill 41 on the guide plate 4, the upper and lower both sides of guide plate 4 have lock hole 42 and rounded tip apical tooth, in gathering sill 41, be provided with the steady pin 16 that is fixed on the hull shape lock body 1, this groove top is arranged in draw-in groove 31, locking lock 32 on the clamp 3 enters in the lock hole 42, can be with the lock locking.
Offer the screw that penetrates hull shape lock body 1 on the bottom surface of lock end watch box 8, can adopt cup head root fastening bolt will lock and connect together, strengthened the whole tightness of lock with door.
Be fixed with the rotating disk 11 of band straight pin on the hull shape lock body 1; Knob 12 is installed on the lock box 2, and inside is provided with rotating disk 13, and rotating disk 13 also has straight pin, is used for opening and closing in door door lock.
When locking a door, insert key and rotation, rotating disk 11 rotates thereupon.At this moment, the straight pin on the rotating disk at first overcomes the active force of torsion spring 14, and clamp 3 is upwards pushed up, and stop pin 32 is deviate from from lock hole 42, and then straight pin is stirred the rounded tip apical tooth, drives guide plate 4 motions.This motion passes to the dead bolt 9 at two ends respectively by connecting plate 10 and linkage 5, slide plate 6, connecting rod 7, connecting plate 10, make dead bolt 9 enter lock nose one-level.Dead bolt whenever advances one-level, and clamp just resets under the effect of torsion spring, and stop pin falls into lock hole, blocks guide plate, prevents that dead bolt from being dialled back.The key revolution moves a week, just repeats above-mentioned a series of actions, until locked.
Motion process when unblanking is also like this, and just the direction of motion is opposite.
In door, adopt the process of knob 12 switching door locks similar to the above process.
