Abstract

A pin lock, comprising a lock body, a lock core is installed in the lock body, a round pin pin is installed in the lock core, a groove is opened in the lock body, a flat pin pin is installed in the groove, and the flat pin pin has a matching The spring and sealing pin, the lock cylinder socket and the round-headed pins are matched with the key. The groove is divided into upper and lower parts. The diameter of the lower part is larger than the diameter of the upper part. Bullet height. Because the diameter of the round-headed pin is greater than the upper diameter of the groove in the lock body, even if chewing gum etc. are used to insert it, the round-headed pin can't all be pushed into the lock body groove, thereby playing an anti-theft effect well. Simultaneously, the utility model has simple structure and convenient operation.

Description

Cylinder lock set

(1) technical field

The utility model relates to a kind of cylinder lock, mainly is applicable to all kinds of door locks.

(2) background technology

The use of lock is extremely extensive, people almost want every day and lock is come into contacts with, for example pass in and out the door lock of door etc., application difference according to lock, mechanical strength and firm performance are also different, but for mechanical anti-theft lock, anti-technical unlocking is stolen to be most important function, present more common theftproof lock, because structural defective, after using unlocking tool that lock core is rotated an angle, in lock core, fill in the thing of chewing gum one class, all the top is behind lock core the round end pellet shot from a slingshot in the lock core, and what inserts lock core can both unblank, thereby has had a strong impact on the safe antitheft performance of lockset.

(3) summary of the invention

In order to solve the shortcoming that existing common theftproof lock is opened by the thief easily, the utility model provides a kind of theftproof performance good cylinder lock set.

The technical solution adopted in the utility model is for this reason: a kind of cylinder lock set, comprise a lock body, lock core is installed in the described lock body, the round end pellet shot from a slingshot is installed in lock core, in lock body, offer groove, the tack pellet shot from a slingshot is installed in the described groove, the tack pellet shot from a slingshot has spring and the offset that matches, lock core jack and round end pellet shot from a slingshot cooperate with key, described groove is divided into two parts up and down, lower diameter is greater than upper diameter, the upper diameter of described groove less than the diameter of round end pellet shot from a slingshot and groove lower height less than round end pellet shot from a slingshot height.

In addition, a kind of cylinder lock set, comprise a lock body, lock core is installed in the described lock body, the round end pellet shot from a slingshot is installed in lock core, in lock body, offer groove, the tack pellet shot from a slingshot is installed in the described groove, the tack pellet shot from a slingshot has spring and the offset that matches, and lock core jack and round end pellet shot from a slingshot cooperate with key, the height of a round end pellet shot from a slingshot peace pellet shot from a slingshot and greater than the degree of depth of described groove.

The beneficial effects of the utility model are: because the diameter of round end pellet shot from a slingshot greater than the diameter of groove in the lock body, so promptly uses chewing gum etc. to fill in, can not the round end pellet shot from a slingshot all be pushed up in the lock body groove, thereby played antitheft effect well; Perhaps as a same reason, the height of a round end pellet shot from a slingshot peace pellet shot from a slingshot and greater than the degree of depth of groove in the lock body has so also been realized and can not all have been pushed up the round end pellet shot from a slingshot in the lock body groove, has realized anti-theft feature.Simultaneously, the utility model is simple in structure, and is easy to operate.

(5) specific embodiment

Embodiment one:

With reference to accompanying drawing 1, a kind of cylinder lock set comprises a lock body 1, and lock core 2 is installed in the described lock body, round end pellet shot from a slingshot 3 is installed in lock core, offer groove 4 in lock body, tack pellet shot from a slingshot 5 is installed in the described groove, the tack pellet shot from a slingshot has spring and the offset that matches, lock core jack and round end pellet shot from a slingshot cooperate with key, described groove is divided into up and down two parts, and lower diameter 6 is greater than upper diameter 7, the upper diameter 7 of described groove less than the diameter of round end pellet shot from a slingshot and groove lower height less than round end pellet shot from a slingshot height.

Embodiment two:

With reference to accompanying drawing 2, a kind of cylinder lock set, comprise a lock body 1, lock core 2 is installed in the described lock body, round end pellet shot from a slingshot 3 is installed in lock core, in lock body, offer groove 4, tack pellet shot from a slingshot 5 is installed in the described groove, the tack pellet shot from a slingshot has spring and the offset that matches, and lock core jack and round end pellet shot from a slingshot cooperate with key, the height of a round end pellet shot from a slingshot peace pellet shot from a slingshot and greater than the degree of depth of described groove.

Owing to structural reason, all break away from lock core thereby limited the round end pellet shot from a slingshot, enter in the groove in the lock body, thereby reached antitheft effect.
