Abstract

The utility model discloses a lock head with a lock core which can idle run, the lock head comprises a lock body, an idle runing core and a lock core sleeve. The lock head is characterized in that the lock core sleeve and the idle running core are together positioned in the inner hole of the lock body after the idle running core is nested by the lock core sleeve, an idle running pin slot is arranged in the idle running core, and an idle running pin is arranged in the idle running pin slot, and a surface A and a surface B are arranged on the idle running pin; a side pin hole is arranged on the corresponding position of the idle running core with the surface A or the surface B, and a side pin is arranged in the side pin hole, and a surface D and a surface C on the side pin are mutually matched with the surface A and the surface B on the idle running pin; an unlock clutch pin hole is arranged on the positions where the lock core sleeve corresponding with the side pin hole; a locking hole is arranged on the positions where the lock body corresponding to the unlock clutch pin hole; an unlock clutch pin is arranged inside the unlock clutch pin hole and the side pin hole, and the position of the unlock clutch pin is adjacent to the side pin hole, the lock head has the advantages that when the lock is locked, the idle running core is under the idle running state, if the padlock removing device is inserted , the idle running core can be arbitrarily rotated, but the lock can not be unlocked, therefore, the lock head has good functions of defending the force unlocking and the technical unlocking.

Description

A kind of tapered end of lock core idle running

Technical field

The utility model relates to a kind of lockset, especially a kind of tapered end of lock core idle running.

Background technology

Usually cylinder lock locks the lock core rotation by pellet shot from a slingshot, and each the pellet shot from a slingshot group in the lock is by two formations.When unblanking, the contact surface of two pellets shot from a slingshot overlaps with the contact surface of lock core and lock body, and the relative lock body of lock core is rotatable; During locking, the contact surface of the contact surface of two pellets shot from a slingshot and lock core and lock body staggers, because the barrier effect of pellet shot from a slingshot, lock core cannot rotate.

This problem that is latched in is: after the special instrument of high strength and toughness inserts lock core, when reversing lock core by force, stop that the pellet shot from a slingshot that lock core rotates will be twisted off, thereby make this lock lose anti-theft feature.

Summary of the invention

The purpose of this utility model provides a kind of idle-run lock head that can overcome existing defective in the prior art, its idling core is in idling conditions when locking, insert unlocking tool or other object, can rotate idling core arbitrarily, but can't unblank, have that very strong defence brute force is unblanked and the function of skilled unlocking.

Technical solution adopted in the utility model is:

After the lock core cover entangles idling core, be placed in together in the endoporus of lock body, in idling core, have the idle running cotter way, be provided with idle pins in the idle running cotter way, have A face or B face on the idle pins, have the side pin-and-hole on the relevant position of idling core and A face or B face, be provided with the side pin in the side pin-and-hole, D face on the side pin or C face match with A face or B face on the idle pins; On lock core cover and the corresponding position of side pin-and-hole, have the clutch pin-and-hole of unblanking, lock body with unblank to have lock hole on the corresponding position of clutch pin-and-hole, clutch pin-and-hole and side pin-and-hole the inside is provided with the on-of pin of unblanking unblanking, its position next-door neighbour's side pin, unblank an end of on-of pin in the hole of lock core cover, and the other end is in the hole of lock body, perhaps, unblank an end of on-of pin in the hole of lock core cover, and the other end is in the hole of idling core.

The on-of pin of unblanking can have one or more.A face on the idle pins or B face can have one or morely, and D face on the side pin with matching or C face also can have one or more, and when cancellation side pin, E face that unblank on-of pin and idle pins match or F face also can have one or more.

When unblanking, when key inserts, the tartar of key promotes pellet shot from a slingshot and moves, idle pins moves axially under the effect of spring, and its contact surface falls into pellet shot from a slingshot Connected in star, idle pins inwardly moves along the footpath of idling core by wedge shape control side pin, the moving of side pin can be controlled the on-of pin of unblanking again and to move, when its end face of side pin-and-hole that enters idling core when the on-of pin of unblanking is concordant substantially with the external cylindrical surface of lock core cover, the on-of pin of unblanking is stuck between lock core cover and the idling core, the lock core cover is connected as a single entity with idling core, at this moment twists key and just can open lock.

During locking, extract key, pellet shot from a slingshot all resets under the effect of spring, pellet shot from a slingshot

Connected in star promotes idle pins moving axially along idling core, idle pins outwards moves along the footpath of idling core by wedge shape control side pin, the moving of side pin can be controlled the on-of pin of unblanking again and to move, enter the lock hole of lock body when the on-of pin of unblanking, tapered end is in closure state, at this moment idling core is free to rotate and can't unblank, and can defend brute force to unblank and technology unlocking.
