Description

A kind of eccentric lockset

Technical field

The utility model relates to lockset, especially a kind of lockset of off-centre.

Background technology

The lockhole of general lockset all is arranged on middle position, and the robber is easy to grasp this structure and easily lock is opened.

The utility model content

The utility model provides a kind of lockset of off-centre at the above-mentioned defective of prior art, to improve the lockset anti-theft capability.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of eccentric lockset, comprise lock handle and the key supporting with it, lock handle is made up of body and latch hook, and both sides, body upper end are respectively equipped with perforation and button hole, the bottom is provided with lockhole, latch hook one end is embedded in the button hole, and the other end passes in the perforation insertion body and with spring and touches, and laterally is provided with plural number in the body to block, be provided with spring between block and the body wall, each is to the opposing end surface mutual extrusion touching of block, and block touching place departs from the lockhole center, and block touching end downside is provided with arc-shaped transition; The latch hook below also is provided with a slide block in the described body, and slide block is positioned at the block top, and the latch hook in this slide block one end and the button hole interlocks and bumps with the right side spring is crowded; Described key has a pinnacle, and it is corresponding that the vertical position that key center and block touch is mutually departed from this pinnacle, departs from the position, pinnacle in the key and be set to hollow-core construction, the built-in cover spoon of this hollow-core construction; Also be provided with a lock core in the described body, this lock core is a rotatable eccentrically weighted shaft, and it is positioned at the top of block, the left of slide block, and touch mutually with the slide block left end; Lock core bottom and cover spoon are positioned at same vertical line, and mate with cover spoon top shape.

Preferably, described block is that 2-4 is right.

As can be seen from the above technical solutions, the position that the utility model block is touched mutually is set to depart from the lockhole center, after inserting, general key can only touch the block on the limit that keeps left, not entering lock core unblanks, have only the identical key in the inconsistent position of tip location and block just can enter lock core, strengthened the anti-theft capability of lockset; Further, the utility model is sheathed cover spoon in key, the structure of utilizing this cover spoon top and lock core bottom to be complementary can turn lock core, because lock core is a rotatable eccentrically weighted shaft, when lock core was turned, eccentrically weighted shaft pushed the slide block of touching mutually with lock core, clasp and latch hook on the slide block are broken away from, open lockset, the design of key kit in this key makes to the utlity model has stronger anti-theft capability.

The specific embodiment

Below in conjunction with the specific embodiment the utility model is described in further detail.

Referring to Fig. 1, Fig. 2 and shown in Figure 3, a kind of eccentric lockset of the utility model, comprise lock handle 1 and the key 2 supporting with it, lock handle 1 is made up of body 11 and latch hook 10, both sides, body upper end are respectively equipped with perforation 111 and button hole 110, the bottom is provided with lockhole 112, latch hook 10 1 ends are embedded in the button hole 110, the other end passes in the perforation 111 insertion bodies 11 and with spring and touches 113, laterally be provided with plural number in the body 11 to block 114, be provided with spring 115 between block and the body wall, each is to the opposing end surface mutual extrusion touching of block, block touching place departs from the lockhole center, and block touching end downside is provided with arc-shaped transition 116; The latch hook below also is provided with a slide block 117 in the described body, and slide block 117 is positioned at block 114 tops, in these slide block 117 1 ends and the button hole 110 latch hook 10 interlock and with right side spring 118 crowded bumping; Described key 2 has a pinnacle 21, and it is corresponding that the vertical position that key center and block touch is mutually departed from this pinnacle, departs from 21 positions, pinnacle in the key and be provided with hollow-core construction 22, a built-in cover spoon 22` in this hollow-core construction; Also be provided with a lock core 119 in the described body, this lock core is a rotatable eccentrically weighted shaft, and it is positioned at the top of block 114, the left of slide block 117, and touch mutually with the slide block left end; Lock core 119 bottom center and a cover spoon 22` are positioned at same vertical line, and mate with cover spoon top shape.

As preferred implementation of the present utility model, described block is that 2-4 is right.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
