Abstract

The utility model discloses an anti-picking lock, comprising a lock barrel arranged in a lock case, the lock barrel drives the expansion and contraction of a lock bolt through an interlock part, a guide post and a lock bolt connected with the lock bolt plate to drive the multi-way locking bar. A lock hook is arranged in the lock bolt, the lock hook can be rotated around the rotating shaft, and the rotating shaft of the lock hook is arranged in the lock bolt. Because the lock hook is arranged in the lock bolt, when in a locking state the lock bolt can lock the door case and lockset panel together to make the lockset have satisfactory anti-picking performance. The interlock part comprises a connecting plate connected with the lock bolt plate with a pin, a relevant slot for the pin is arranged on the turning block, a relevant clip is arranged in the slot, the lock barrel can shift the turning block to rotate, and the shifting end is arranged on the connecting plate; a movable lock bolt is arranged to move along the lock bolt plate, a lock catch can be touched by the movable lock bolt which is arranged on the rear end of the movable lock bolt and a hook for cooperation with the hook column is arranged in the lock catch.

Description

Pick-proof lock

Technical field:

The utility model relates to lock technology field, particularly a kind of pick-proof lock.

Background technology:

The dead bolt of existing theftproof lock all locks door leaf and doorframe in the straight cutting mode.Theftproof lock locking back adopts brute force can promote the dead bolt retraction, makes that the pick-proof performance of lockset is undesirable.The mode of indoor insurance dead bolt is generally all adopted in the indoor insurance of existing theftproof lock, adopts this mode to insure safety tongue, and multidirectional locking bar and main dead bolt still can bounce back under the compressing of external force.The movable contact of existing automatic locking all is provided with separately, makes antitheft automatic locking complex structure, the manufacturing cost height.

Summary of the invention:

At above deficiency, the inventor has proposed a kind of simple in structure, pick-proof lock that the pick-proof performance is good.It comprises: be located at the lock core in the lock housing, it is flexible that lock core drives dead bolt by moving part, is connected with the guide pillar and the dead bolt that are used to promote multidirectional locking bar on the bolt plate.Be provided with latch hook in the described dead bolt, latch hook can rotate around its rotating shaft, and the latch hook rotating shaft is installed in the dead bolt.Because be provided with latch hook in the dead bolt, dead bolt is when lock-out state, latch hook locks doorframe and panel of lock together, makes lockset that good pick-proof performance be arranged.When unblanking, latch hook rotates around its rotating shaft, makes dead bolt withdraw from doorframe easily, and pick-proof lock is opened.

In the utility model, described moving part comprises: with the junction plate of the mutually related pin of bolt plate, moving block is provided with this pin and slots accordingly, is provided with in this fluting and the corresponding card division of pin, lock core can be stirred moving block and rotate, and junction plate is provided with the lock core struck side; Dead bolt is provided with a moving dead bolt that can move along bolt plate, moving dead bolt rear end be provided with can passive dead bolt touching snap close, be provided with the pothook that matches with the hook post in the snap close.The course of work of the present utility model is as follows: when unblanking, lock core is stirred moving block, makes pin break away from the card division, and lock core is stirred junction plate again and just can be driven the dead bolt retraction at this moment, and the grab of snap close just hooks the hook post.When locking, the moving dead bolt of doorframe touching, moving dead bolt touches snap close, makes the grab of snap close break away from the hook post, and dead bolt just automatically locks under the effect of spring, makes this lockset function that automatically locks.Pin on the utility model junction plate has auto-lock function when snapping in the card division.

In the utility model, be provided with the insurance driving lever that matches with lock core in the described lock housing, the insurance driving lever can promote safety block turnover junction plate rear portion, and the manual safety dial axis links to each other with safety block by the manual safety bar.When safety block entered the junction plate rear portion, junction plate was just withstood, and dead bolt is insured.When opening the lock with the key, lock core is stirred the insurance driving lever earlier, and safety block is released the junction plate rear portion, just can unblank.

In the utility model, be provided with the handle dial axis in the described lock housing, the handle dial axis can be stirred moving block, and the moving block fluting can drive the junction plate of pin; The handle dial axis is made up of two rotatable relatively inside and outside handle dial axises, is located at pin-and-hole on the outer handle dial axis, and latch can pass in and out this pin-and-hole under the effect of motor.Adopt said structure, the utility model can match with electronic circuits such as IC-card circuit, fingerprint recognition circuit, radio circuits and make electronic lock.

The specific embodiment:

In conjunction with Fig. 1, shown in Figure 2: the pick-proof lock of present embodiment comprises: be located at the lock core 2 in the lock housing 1, be connected with the guide pillar 5 and the dead bolt 6 that are used to promote multidirectional locking bar 4 on the bolt plate 3.Bolt plate 3 is connected with the junction plate 8 of band pin 7, and moving block 9 is provided with and the corresponding fluting 10 of this pin, is provided with in this fluting and pin 7 corresponding card divisions 11.Lock core 2 can be stirred moving block 9 and rotate, and junction plate is provided with the lock core struck side.Dead bolt is provided with a moving dead bolt 12 that can move along bolt plate, moving dead bolt rear end be provided with can passive dead bolt touching snap close 13, be provided with the pothook that matches with hook post 14 in the snap close 13.Be provided with the insurance driving lever 15 that matches with lock core 2 in the lock housing, the insurance driving lever can promote safety block 16 turnover junction plate rear portions, and manual safety dial axis 17 links to each other with safety block by manual safety bar 18.

The course of work of the present utility model is as follows: when unblanking, lock core is stirred moving block, makes pin break away from the card division, lock core is stirred the insurance driving lever simultaneously, and safety block is released the junction plate rear portion, and lock core is stirred junction plate again and just can be driven the dead bolt retraction at this moment, the grab of snap close just hooks the hook post, and dead bolt is located.When locking, the moving dead bolt of doorframe touching, moving dead bolt touches snap close, makes the grab of snap close break away from the hook post, and dead bolt just automatically locks under the effect of spring 19.

When needs carry out indoor insurance, stir the manual safety dial axis, when the manual safety dial axis just can push the junction plate rear portion with safety block, the junction plate piece that is insured withstood, and just finished the dead bolt insurance, and this moment, key can not be opened.

As shown in Figure 3, Figure 4: be provided with latch hook 23 in the dead bolt 6, latch hook can rotate around its rotating shaft 24, and latch hook rotating shaft 24 is installed in the dead bolt 6.Dead bolt is when lock-out state, and latch hook locks doorframe and panel of lock together, makes theftproof lock have good pick-proof performance.When unblanking, latch hook rotates around its rotating shaft, makes dead bolt withdraw from doorframe easily, and theftproof lock is opened.
