Abstract

The utility model discloses a multi-set door lock using the same key, which is provided with a lock core, a lock base and a lock piece. Marble and springs are arranged in marble holes of the lock base by screws, and the marble holes are numbered in sequence. The key comprises a main key and a plurality of auxiliary keys with different numbers, the number of the main key is the same as the sequential number of the marble holes, and the tooth shapes of the auxiliary keys are other arrangement and combinations of the tooth shape of the main key and are edited with the corresponding number. One key can open a plurality of locks with the same model number of the marble lock core. When the key is replaced, the screws are screwed down, and the marbles are exchanged according to the number of the auxiliary keys. The utility model not only solves the problem that a plurality of locks and keys are arranged in modern living rooms, but also can replace the key automatically at any time.

Description

Many covers are with the spoon convenient door lock

The utility model relates to door lock, and particularly a kind of many covers are with the spoon convenient door lock.

At present, our door lock used in everyday all is single cover, a key can only be opened a lock set, and key can not be shared, and the pellet shot from a slingshot of door lock and spring are to utilize plug that the two is placed in the pellet shot from a slingshot hole of lock, the user can not change pellet shot from a slingshot voluntarily, change key, so the trouble of using is extremely inconvenient, service time is long more, and safety, security performance are poor more.

The purpose of this utility model provides many covers with the spoon convenient door lock, to solve the deficiencies in the prior art part.

The technical solution of the utility model is achieved like this: many covers are with the spoon convenient door lock, have lock core, lock and locking plate, lock core is inserted in the lock, its tail end is fixed with locking plate, it is characterized in that pellet shot from a slingshot and spring are placed in the pellet shot from a slingshot hole on the lock with screw, its pellet shot from a slingshot hole numbers in order, key has one of the different master key of numbering and some secondary key, number on the master key is identical with the serial number in pellet shot from a slingshot hole, and the profile of tooth of secondary key is other permutation and combination of master key profile of tooth, and compiles and go up respective number.

Many covers that the utility model provides are with the spoon convenient door lock, only can open the same identical some lock sets of lock cylinder structure model if must change key with a key, the user can back out the screw on the lock voluntarily, according to pair number transposing pellet shot from a slingshot on the key, the modern room problems of locking many spoons had both been solved more, again can be at any time the pellet shot from a slingshot in the homology functor hole be not done transposing mutually by secondary number on the key, to improve the security performance of door.

Accompanying drawing is the utility model example structure schematic diagram.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
