Abstract

The utility model relates to a key-typed cipher cylinder lock, comprising a lock core, a lock body and a surface cover. One side of the lock body is provided with the lock core, the lower side of the lock core is provided with springs and the upper side is fixed with a lock bending head, and the corresponding point of the lock core and the side surface of the other side of the lock body is bored with more than one hole. The inner part of the holes on the lock core is provided with the springs and cylinders, and the inner part of the holes on the lock body is provided with the springs, cipher keys or non-cipher keys. The key-typed cipher cylinder lock can be made into a drawer lock or various vehicle locks after the lock bending head is changed into a lock tongue. The utility model has the advantages of simple structure, low cost, convenient operation and high confidential coefficient.

Description

Key puzzle cylinder lock

The utility model relates to lock, particularly a kind of button password night lock.

Existing commercially available coded lock, as the electron type coded lock, electronic component is many, complex circuit, the cost height, moisture-sensitive is damaged; The mechanical type coded lock, then secret coefficient is low, and it is loaded down with trivial details to encode, and use is inconvenient, volume is big, is difficult for promoting.

The purpose of this utility model is to provide a kind of structure comparatively simple, need not power supply and key, and cost is low, password night lock easy to use.

Technical solution scheme of the present utility model is such, this lock comprises core, lock body, cover and more than one spring, pellet shot from a slingshot, cryptographic key and non-cryptographic key, lock body is placed core on one side, spring is arranged below the core, top pin elbow, core and the mutual more than one hole of corresponding brill, lock body side, the hole built-in spring of core, pellet shot from a slingshot, the hole built-in spring of lock body, cryptographic key or non-cryptographic key.When unblanking, press cryptographic key simultaneously, directly compress pellet shot from a slingshot in the core, spring by cryptographic key, core moves under the effect of spring force, thus the control lock elbow unblank, when shutting, press the lock elbow and put in place, promptly realize shutting.

The utility model has the advantages that simple in structurely, low, easy to use, the secret coefficient height of cost is applicable to family expenses locks and lock.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structure cut-open view of final assembly of the present utility model.

Fig. 2 is a cryptographic key part sectional view of the present utility model.

Fig. 3 is a non-cryptographic key part sectional view of the present utility model.

Among Fig. 1, Fig. 2, Fig. 3, lock core (1), cryptographic key (2), non-cryptographic key (3), pellet shot from a slingshot (4), spring (5,6), spring (7), lock elbow (8), cover (9), lock body (10).

Application principle of the present utility model is such: in Fig. 1, password is made as A1, A3, A6, A8 key, as can be seen from Figure, core (1) is blocked by the corresponding pellet (4) of the cryptographic key of its inner A1, A3, A6, A8, lock is in closed condition, if press simultaneously A1, A3, A6, A8 cryptographic key this moment, then its corresponding pellet is compressed, core (1) is not blocked by any pellet this moment, core (1) is under the effect of spring (7), move up and unblank, if press other non-cryptographic key or not entirely by to cryptographic key, then lock can not be opened

Embodiment of the present utility model is such, referring to figs. 1 through Fig. 3, non-cryptographic key is longer slightly than cryptographic key, length makes core not be stuck when pressing password just and is as the criterion, lock body (10) is used to place core (1) on one side, spring (7) is arranged below the core (1), be fixed with lock elbow (8) above, core (1) and 10 holes of corresponding brill, lock body (10) another side side, hole on the core (1) is put spring (6) and pellet shot from a slingshot (4) into, spring (5) and cryptographic key (2) or non-cryptographic key (3) are placed in hole on the lock body (10), and fixedly cover (9) gets final product then.

Another embodiment of the present utility model can make various family expenses locks or all kinds of lock according to above-mentioned structural principle.Promptly lock elbow (8) is become dead bolt, can make drawer-lock or all kinds of lock.

Claims

1, a kind of button password night lock, comprise core (1), lock body (10), cover (9), it is characterized in that lock body (10) places on one side core (1), have below the core (1) spring (7), above be fixed with the lock elbow (8), core (1) and the more than one hole of corresponding brill, lock body (10) another side side, hole built-in spring (6) on the core (1), pellet shot from a slingshot (4), the hole built-in spring (5) on the lock body (10), cryptographic key (2) or non-cryptographic key (3).

2, button password night lock according to claim 1, it is characterized in that a lock elbow (8) becomes dead bolt after, can make drawer-lock or all kinds of lock.
