Description

A kind of safe lock cylinder with spherical pellet shot from a slingshot and segmentation lock core

Technical field

The utility model relates to the cylinder lock technical field, relates in particular to a kind of multistage pellet shot from a slingshot that has, and the lowest segment pellet shot from a slingshot is buckshot, and lock core is divided into two sections safe lock cylinder.

Background technology

Daily lock major part is single core list key, and it is convenient to open, but poor safety performance is easily pried open with simple tool by stealer.

It is to adopt locked groove to drive pellet shot from a slingshot to reach the purpose of unblanking that a kind of lock is arranged in the prior art, and just the user inserts locked groove in the lock core with key, and key moves pellet shot from a slingshot.

How to reach on the basis of this lock core that stealer can not be unblanked easily is the problem that the designer will solve.

The utility model content

The utility model technical issues that need to address have provided a kind of safe lock cylinder with spherical pellet shot from a slingshot and segmentation lock core, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the utility model comprises: preceding lock core, rear lock core, 1 to No. 5 pellet shot from a slingshot group, 1 to No. 5 pellet shot from a slingshot hole; Comprise described rear lock core and preceding lock core adjacent being installed in the lock body on same line; Lock core comprises before described: preceding lock core shell, locating slot, jump ring one, No. 1 pellet shot from a slingshot hole, No. 2 pellet shot from a slingshot holes; Described rear lock core comprises: back lock housing, jump ring two, No. 3 pellet shot from a slingshot holes, No. 4 pellet shot from a slingshot holes, No. 5 pellet shot from a slingshot holes; Described 1 to No. 5 pellet shot from a slingshot group has 5 groups, and every group comprises: go up pellet shot from a slingshot, pellet shot from a slingshot, spherical pellet shot from a slingshot, spring down, and be on the same vertical line, can be fitted into respectively in 1 to No. 5 pellet shot from a slingshot hole; Described pellet shot from a slingshot, following pellet shot from a slingshot and the spherical pellet shot from a slingshot gone up is in compressive state at spring after the pellet shot from a slingshot hole is allocated in 1 to No. 5 pellet shot from a slingshot assembling into, and makes pellet shot from a slingshot, following pellet shot from a slingshot, spherical pellet shot from a slingshot be in overstocked abutting orientation.Described jump ring one and locating slot size be close-fitting mutually.The physical dimension of the spherical pellet shot from a slingshot in described each pellet shot from a slingshot group is identical, and the last pellet shot from a slingshot in described every group of pellet shot from a slingshot is different with following pellet shot from a slingshot length, but the length sum is identical, and use that can be by key and rotational lock core are realized the switch of lock.

Compared with prior art, the beneficial effects of the utility model are: keep key constant, the custom that does not change the user unblanks with operation to have promoted the security performance of locking greatly under the simple situation of process.

Fig. 1 is the utility model stereogram.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 1, the utility model comprises: preceding lock core 1,3,1 to No. 5 pellet shot from a slingshot holes 4 of 2,1 to No. 5 pellet shot from a slingshot groups of rear lock core; Comprise described rear lock core 2 and preceding lock core 1 adjacent being installed in the lock body on same line; Lock core 1 comprises before described: preceding lock core shell 11, locating slot 12,41, No. 2 pellet shot from a slingshot holes 42,13, No. 1 pellet shot from a slingshot hole of jump ring; Described rear lock core 2 comprises: back lock housing 21,44, No. 5 pellet shot from a slingshot holes 45,43, No. 4 pellet shot from a slingshot holes, 2 22, No. 3 pellet shot from a slingshot holes of jump ring; Described 1 to No. 5 pellet shot from a slingshot group 3 has 5 groups, and every group comprises: go up pellet shot from a slingshot 31, pellet shot from a slingshot 32, spherical pellet shot from a slingshot 33, spring 34 down, and be on the same vertical line, can be fitted into respectively in 1 to No. 5 pellet shot from a slingshot hole 4; Described pellet shot from a slingshot 31, following pellet shot from a slingshot 32 and the spherical pellet shot from a slingshot 33 gone up is in compressive state at spring 34 after 1 to No. 5 pellet shot from a slingshot group 3 is fitted into pellet shot from a slingshot hole 4, and makes pellet shot from a slingshot 31, following pellet shot from a slingshot 32, spherical pellet shot from a slingshot 33 be in overstocked abutting orientation.Described jump ring 1 and locating slot 12 sizes are close-fitting mutually.The physical dimension of the spherical pellet shot from a slingshot 33 in described each pellet shot from a slingshot group 3 is identical, and the last pellet shot from a slingshot 31 in described every group of pellet shot from a slingshot 3 is different with following pellet shot from a slingshot 32 length, but the length sum is identical, and use that can be by key and rotational lock core are realized the switch of lock.

Make when opening the lock with the key the user, by the key tooth of differing heights on the key, make last pellet shot from a slingshot and following pellet shot from a slingshot intermediate gap in the pellet shot from a slingshot group sentence with the same horizontal plane of lock core shell external surface on, can realize the rotation of lock core.

Preceding lock core and rear lock core constitute the agent structure of whole lock core, and wherein rear lock core is fixedlyed connected with external door, and preceding lock core is fixedlyed connected with door, and rear lock core blocks dead bolt by jump ring two.Former and later two lock core devices make key must drive two lock cores and rotate simultaneously and can unblank,

The utility model beneficial effect is to keep key constant, does not change user's custom and psychology In the situation of sensation, key must drive two lock cores and rotate simultaneously and can unblank, and stealer can't be light Easy-to-use tool is pried open, and different picking locks that increased from lower spring length of the upper pellet of pellet on the same group not Difficulty has promoted the security performance of locking greatly.
