Abstract
The utility model relates to a lock part for a cylinder lock, which is composed of a lock core sleeve and a lock core arranged in a lock core hole of the lock core sleeve, wherein, both sides of a key slot on the lock core are made into a symmetrical type and a return apparatus which can cause semi-circular end cylinders to return to cylinder holes above the key slot.
Description
The utility model relates to the tapered end parts on a kind of cylinder lock, particularly cylinder lock.
Existing tapered end parts (as shown in Figure 1) all are made up of lock core cover 3 and the lock core 6 in the lock core hole that is contained on the lock core cover 3, in the pellet shot from a slingshot hole 7,9 of lock core cover 3 and lock core 6 spring 2, tack pellet shot from a slingshot 4 and cup head pellet shot from a slingshot 5 are housed, and seal with plug 1.After the key 8 of key from the lock core 6 transferred to, tack pellet shot from a slingshot 4 was between the bonding surface of lock core hole on the lock core cover 3 and lock core 6, relies on tack pellet shot from a slingshot 4 to limit the rotation of lock core 6, and at this moment, cup head pellet shot from a slingshot 5 drops in the key 8.When his foreign matter of apparatus inserted in the key 8 without key, the foreign matter of insertion can directly contact cup head pellet shot from a slingshot 5, thereby may cause lock core 6 to rotate and reach and steal the purpose of locking.
The purpose of this utility model provides a kind of novel tapered end, and after key was transferred to from lock core, the semicircle pellet shot from a slingshot was in the top of key, and the foreign matters of inserting in the key touches pellet shot from a slingshot.
Technical solution of the present utility model is such, it comprises whole features of existing tapered end, by lock core cover and the lock core that is contained in the lock core hole that lock core puts forms, lock core overlap and lock core on the pellet shot from a slingshot hole in spring, tack pellet shot from a slingshot and cup head pellet shot from a slingshot are housed, and seal with plug.It is characterized in that the two sides of key are designed to symmetric form, the both sides in each pellet shot from a slingshot hole respectively are provided with one and make the cup head pellet shot from a slingshot be returned to the returning device in the pellet shot from a slingshot hole above the key on key, and returning device is made up of the hoodle in the installing hole that is installed in both sides, key pellet shot from a slingshot hole, spring and plug.After key is transferred in the key, the cup head pellet shot from a slingshot be returned under the effect of returning device key above, rely on the rotation of cup head pellet shot from a slingshot restriction lock core, after in key inserts key, the hoodle of returning device, in the withdrawal installing hole, the cup head pellet shot from a slingshot is fallen in the key tooth flower, and this moment, lock core was rotatable.
The tapered end that the utility model provides, after key is transferred to, the cup head pellet shot from a slingshot will be returned in the pellet shot from a slingshot hole of key top, directly contact the cup head pellet shot from a slingshot to prevent foreign matter, thereby play antitheft effect.
