Description
Affiliated technical field
Background technology
The utility model is to belong to a kind of improved anti-theft lock end.
Existing common door lock has cylinder lock, padlock, page or leaf sheet cylinder lock, fingerprint gate lock and electronic digit door lock, and the lock core of common spring lock and padlock is by shooting son in a plurality of bullet groove, and double wedge on the key compresses pellet shot from a slingshot and opens tapered end, and its anti-theft feature is poor; The digital door lock of electronic type, fingerprint gate lock etc. use limited, the cost height, and when outage, fault, can not open door lock; Page or leaf sheet cylinder lock is mainly by dead bolt, lock core, dial, retainer spring and shell, its lock core is made up of page or leaf sheet, pad, spring, dial, lock core rotating cylinder and shell, the lock core rotating cylinder can be adorned 7 page or leaf sheets, the double wedge of the keyhole in the page or leaf sheet is a symmetric shape, the groove on its key two sides is symmetric shape thereupon also, the group/cording quantity of lock is few, and the mutual opening rate height of lock is dangerous.
Summary of the invention
The purpose of this utility model provides good, the moderate novel anti-burglar lock of a kind of theftproof performance.
Anti-theft lock end of the present utility model is to open cylindrical hole by the tapered end shell, fixed lock core in the cylindrical hole, lock core is equipped with a page sheet, brake(-holder) block and pilot pin, brake(-holder) block has groove, come the motion of correcting brake(-holder) block with the pilot pin of lock core, pilot pin and braking pellet shot from a slingshot are on same straight line, braking pellet shot from a slingshot and tripping spring are fixed in the slotted eye of tapered end shell, the side compression locking pellet shot from a slingshot of page or leaf sheet and locking spring, locking pellet shot from a slingshot and locking spring are fixed in the slotted eye of tapered end shell, 90 ° of right angles between the slotted eye of the slotted eye of braking pellet shot from a slingshot and tripping spring and locking pellet shot from a slingshot and locking spring, the page or leaf sheet, locking pellet shot from a slingshot and brake(-holder) block form 3 locking modes, and theftproof performance improves.Sword iron partly is to connect the clutch spring by the clutch-plate in the lock core, the clutch spring connects sword iron, sword iron connects the sword iron spring, the sword iron spring connects lock core tail cover, lock core tail cover is fixed on the lock core tail end and forms, the sword iron head end has a breach, resilient key in the lock core is the alignment pin of clutch-plate, when key inserts lock core, key tail end compression clutch-plate and clutch spring, clutch-plate tail end compression sword iron and sword iron spring, this moment, lock core remained idle running, sword iron is not action still, when lock core goes to a certain angle, after the clutch-plate tail end inserts the breach of sword iron head end, sword iron and lock core rotate simultaneously, lock body is opened, lock core, clutch-plate and sword iron form clutch mode, and theftproof further improves.The direction of key two heel teeths is opposite.
Of the present utility model rational in infrastructure, there are double anti-theft, pick-proof performance good, reasonable price.
