Abstract

The utility model relates to a safe-guard door lock, which is characterized in that a lock-up box provided with a hole on an upper cover is arranged in a box shaped lock body close to a bolt extending hole, a lock-up pin which can extend and contract up and down is arranged above the lock-up box and a bolt; when the latch extends out and goes into a bolt box, the lock-up pin falls down to lock the bolt, the bolt can not be forced open by external force, thereby achieving an anti-theft function. In addition, a pair of reversible pliers shaped blocks is arranged in the bolt box, after the latch stretches into the bolt box, the pliers shaped blocks block the bolt to ensure that the latch can not drop out when external force picks the door, thereby having pickproof and anti-theft effect.

Description

Antitheft retrocession lock

Technical field:

The utility model is a kind of improved safe-guard door lock.

Background technology:

Existing Chang Yong safe-guard door lock when external force is forced open the door with hard device, all easily produces distortion and displacement between dead bolt box and doorframe, dead bolt box and the dead bolt, make that dead bolt is deviate from the dead bolt box, door is opened by external force and lose antitheft effect.

Summary of the invention:

A kind of external force is forced open the door by force even the purpose of this utility model is design, and dead bolt can not deviate from from the dead bolt box yet, the antitheft retrocession lock of energy safety pick-proof.

The purpose of this utility model is achieved like this: the position that close dead bolt stretches out the hole in the box-like lock body of theftproof lock is provided with a locking box, but the flexible up and down lock pin of an elasticity is set above this locking box, when dead bolt stretch out enter in the dead bolt box after, lock pin falls and penetrates the locking box dead bolt is blocked, in addition, in the dead bolt box, be provided with a pair of can rotating pincerlike link stopper, after dead bolt enters the dead bolt box, this pincer block blocks dead bolt, even external force is forced open the door dead bolt is deviate from, thereby be played the effect of pick-proof and anti-theft.

It is simple, safe and reliable that the utility model is watched out for robber's retrocession lock construction, can play the safety effect of pick-proof and anti-theft.

pincer block

25,14 respectively have and have the slotted hole groove on the tong arm and be contained in the rotating shaft 13 of drive block 16 with sliding.

When people go out, shut the door, key 29 is inserted in the keyhole of lock core 5, the crown of key 29 is equipped with on the locking plate (not drawing among locking plate and the locking plate spring figure) of locking plate spring a plurality of in the lock core 5 and moves, make and occur a horizontal row hole on the lock core 5, twist outer handle 1 clockwise with hand, driving turning cylinder 3 turns clockwise, owing to have the arc detent on the turning cylinder 3, be that turning cylinder 3 is equivalent to the flute profile positioning cam, pushing two-sided pin 4 moves to left and locatees, many conehead pins that have groove on two-sided pin 4 left surfaces pass the cross-drilled hole on the lock core 5 at this moment, extract key 29 out, locking plate falls under the effect of locking plate spring, snap in the detent of conehead pin, because the conehead pin is blocked by locking plate, outer handle 1 can not reverse, along with turning clockwise of turning cylinder 3, outer bidentate driver blade 8 also clockwise rotates, promoting multiple tooth driver blade 9 is rotated counterclockwise, when multiple tooth driver blade 9 rotates, Xiao's axle 28 on it drives dead bolt 7 and moves to left, dead bolt 7 left end heads pass locking box 23 and pass lock body housing 6 and enter in the dead bolt box 30, the traction of the seizing wire 19 on meanwhile multiple tooth driver blade 9 left side teeth, make the left end of yoke 21 depress lock pin 22, locking Xiao 22 passes the hole of capping on the locking box 23 and inserts in the spill ladder of dead bolt 7 left ends, dead bolt 7 is pinned, external force can not make dead bolt 7 move to right and play the effect of pick-proof, along with moving to left, dead bolt 7 stretches in the dead bolt box 30, dead bolt 7 promotes drive block 16 and moves to left, Xiao's axle 13 on the drive block 16 promotes two pincerlike link stoppers 25 up and down, 14 rotate around expansion bolt 17 separately, forficiform tong arm mates towards the center of dead bolt box 30, block dead bolt 7, make dead bolt 7 be subjected to the locking of tong arm, the external force picking lock also can't reach the purpose of pick-proof and anti-theft with dead bolt 7 displacements.

When people outdoors, in the keyhole on the key 29 insertion lock cores 5, the tooth of key 29 makes on a plurality of locking plates (not drawing among the figure) in the keyhole and moves, releasing is to the locking of a plurality of conehead pins on two-sided pin 4 left surfaces, rotate counterclockwise outer handle 1 with hand then, turning cylinder 3 also is rotated counterclockwise, two-sided pin 4 sets back under the effect of spring, key 29 is extracted, outer bidentate driver blade 8 promotes multiple tooth driver blade 9 and turns clockwise, lift on the left arm of the yoke 21 that is drawn by seizing wire 19, lock pin 22 climbs away the locking to dead bolt 7 under the effect of spring, and dead bolt 7 moves to right and withdraws from dead bolt box 30, meanwhile, drive block 16 in the dead bolt box 30 also moves to right under the effect of spring 26, makes

pincerlike block

25,14 get back to original position, and door can be opened; In operating personnel stand in door, handle 11 in the rotation, interior bidentate driver blade 10 also rotates along with rotating and drive multiple tooth driver blade 9, equally causes dead bolt 7 left and right moving and other a series of locking actions with outer bidentate driver blade 8, realizes the function of antitheft retrocession lock pick-proof and anti-theft.
