Abstract

The utility model relates to a mechanical lock opened by inserting instead of rotation, comprising a shell of a lock body, a lock core, a lock tongue, etc. The lock core is arranged in the shell. The lock core is connected with the lock tongue through a connection mechanism. The lock core is composed of a lock core jacket with a marble groove and a lock inner core, and the lock inner core is sheathed in the lock core jacket and connected with a mechanism of the lock body. The outer wall of the lock core jacket is provided with an oblique guide groove form top to bottom. One end of a pin rod is arranged in the guide groove, and the other end is fixedly arranged on the inner wall of the shell of the lock body. The guide groove can deal with a plurality of corresponding pin rods. The utility model has the advantages of simple operation, simple manufacturing and processing and low cost. When a user unlocks the lock, the lock can be opened only by a key which is smoothly inward pushed without rotating the lock core.

Description

Need not rotate the straight inserting opening mechanical lock

The utility model relates to the key operated mechanical lock of a kind of usefulness, and is especially a kind of after key inserts lockhole, presses under only needing, the mechanical lock that must screw key lock can not opened.

At our daily used mechanical lock, though various structures are arranged, but generally all be that key is inserted in the lock body, after the setting of the bullet groove of on the key indentation and lock core cover matches, utilize key rotation lock inner core again, inner key cylinder drives the opening mechanism action, thereby dead bolt is taken back, and lock is opened.This traditional lock body structure is necessary screw key when operation, so complicated operation, uses inconvenience, because rotatablely moving of lock core need be converted to the straight line of dead bolt moves, the opening mechanism that cooperates is corresponding comparatively complicated, and the accessory of the manufacturing is many, and cost is higher.

The purpose of this utility model is to provide a kind of straight inserting opening mechanical lock that need not rotate at the deficiency of prior art, when unblanking, only needs to insert key the inwardly pushing of taking advantage of a situation, the lock that does not need rotary locking cylinder lock can be opened.

The purpose of this utility model is achieved in that a kind ofly need not rotate the straight inserting opening mechanical lock, it comprises lock body shell and accessories such as lock core and dead bolt, lock core is arranged in the housing, lock core joins by bindiny mechanism and dead bolt, and wherein lock core is made up of the inner key cylinder of the lock core cover that the has bullet groove mechanism that is connected lock body interior with being set in the lock core cover.Be provided with one section oblique from top to bottom guide groove on lock core cover outer wall, an end of a pin is arranged in the guide groove, and the other end is fixedly installed on the shell wall of lock body.

Described guide groove and corresponding pin can be a pair of more than.

According to the technique scheme analysis as can be known, compared with prior art, the utlity model has simple to operate, characteristics such as production and processing is easy, and cost is lower.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model overall structure schematic diagram.

Referring to Fig. 1,2, the utility model is a kind ofly need not rotate the straight inserting opening mechanical lock, it comprises lock body shell 1 and accessories such as lock core 2 and dead bolt 8, lock core 2 is arranged in the housing 1, lock core 2 joins with dead bolt 8 by bindiny mechanism 7, wherein lock core 2 is made up of lock core cover 4 that has bullet groove and the inner key cylinder 3 that is set in the mechanism that is connected lock body in the lock core cover 4, and these accessories and mutual annexation are same as the prior art, so repeat no more.And improvement of the present utility model to be an end that is provided with one section oblique from top to bottom guide groove, 5, one pins 6 on the outer wall of lock core cover 4 be arranged in the guide groove 5, the other end is fixedly installed on shell 1 inwall of lock body.Therefore, after key inserts lockhole, pellet shot from a slingshot in the lock core cover 4 is pushed back in the bullet groove 9, and pushing key, owing between inner key cylinder 3 bottoms and lock core overlap 4, be provided with and be connected shop bolt, therefore can not produce relative displacement at axial direction lock core cover 4 with inner key cylinder 3, so will together move vertically, because the outer wall of lock core cover 4 is tiltedly established guide groove 5, and an end of pin 6 is inserted in the guide groove 5, the other end is fixed in again on lock body shell 1 wall, lock body shell 1 maintains static, therefore pin 6 one ends in the guide groove 5 are inevitable moves along guide groove 5, along with moving that pin 6 makes progress, has driven lock core cover 4 and has moved down rotatably, therefore inner key cylinder 3 is also along with moving down, thereby drive opening mechanism 7 actions, dead bolt 8 is retracted, finish the operation of unblanking.If key is not the key of this lock, so when the pushing key, because all pellets shot from a slingshot that indentation can not overlap lock core on 4 push in the bullet groove 9, pellet shot from a slingshot still is stuck between lock core cover 4 and the inner key cylinder 3, therefore lock core cover 4 can't produce relative rotation with inner key cylinder 3, so inner key cylinder 3 also can't move down, lock is opened thereby can not start opening mechanism 7.

In addition, the guide groove 5 on the lock core cover 4 and the pin 6 on the corresponding lock body shell 1 can be a pair of more than so that stress equalization can ensure finishing smoothly of unlocking action so better.

In sum, the utility model operation is very simple, and the pushing lock core of can taking advantage of a situation when inserting key can be opened lock, and simple to operate, production and processing is easy, and cost is lower.
