Description

A kind of antitheft lock mechanism

Technical field

This utility model belongs to field of lockset, is specifically related to a kind of antitheft lock mechanism.

Background technology

The principle of lock is that the spring marble on lockhole is stuck in lock core, and after key puts in, the pellet in lock core ejects the pellet of lockhole, make lock core can rotate in lockhole, stir the pellet in lock core with the crotch of iron wire, just can eject the pellet of lockhole, thus reach the purpose unblanked.The most conventional is spring lock, and thief just can pry open it with an iron wire less than one minute, therefore there is the potential safety hazard that indoor finance are easily stolen.In view of this, the applicant provides a kind of antitheft lock mechanism, and this case thus produces.

Utility model content

The purpose of this utility model is to provide a kind of antitheft lock mechanism, to solve the technical problem that tradition spring lock is easily pried open.

For achieving the above object, the technical scheme that this utility model specifically provides is: a kind of antitheft lock mechanism, including key, the lockhole mated with key；Described key case spatula handle and the spoon bar of the composition that is connected by some joint units, the both ends periphery of spoon bar is provided with some key bits；Described joint unit includes joint and for being flexibly connected the lever of two adjacent heads.

Further, described lever is cross lever, the adjacent joint location connected by cross lever be 90 degree hinged.

Further, being shaped as of described lockhole is U-shaped, and lockhole includes the two key bit sets mated with key bit, this two key bit set outer peripheral face is movably set with and overlaps, with key bit, the lockhole set mated.

Further, described spoon bar one end is also movably set with a connector tip, and this connector tip is mated with the connector tip set being movably set in lockhole one end, and described connector tip set outer peripheral face is additionally provided with a buckle.

The beneficial effects of the utility model: some joint units are used in combination with by this utility model, it is achieved that key is gone up in any direction and can be rotated, become genuine " flexible shaft ", can transmit moment of torsion, and the most not receive constraint；

Further, lockhole to be designed to the moulding that band angle is even turned with " spatially " so that common picklock cannot insert lockhole.Even if inserting lockhole, due to lockhole non-linear layout, owing to lock core is the most angled, the pellet on lock core cannot be allowed to shift suitable opening device onto, so cannot rotate around certain axis, even if pellet is the least, also cannot directly do cutting movement, thus produce failure by shear, make lock core lose efficacy.

Detailed description of the invention

As Figure 1-4, what this utility model disclosed is a kind of antitheft lock mechanism, and a kind of antitheft lock mechanism, including key 1, the lockhole 2 mated with key 1；Described key case spatula handle 12 and the spoon bar 13 of the composition that is connected by some joint units 3, spoon bar 13 can be designed to different length according to the requirement of concrete rigging, and the length of spoon bar 13 increases only need to increase joint unit 3.

The both ends periphery of spoon bar 13 is provided with some key bits 4, and key bit 4 can be designed to difformity according to different size rigging by key bit 4；Described joint unit 3 includes joint 31 and for the lever 32 being flexibly connected two adjacent 31.

Described lever 32 is cross lever, adjacent joint 31 position connected by cross lever be 90 degree hinged；Being shaped as of described lockhole 2 is U-shaped, and the shape of lockhole 2 can also be Z-type or L-type, and lockhole is designed to the moulding that band angle is even turned with " spatially " so that common picklock cannot insert lockhole.

Lockhole 2 includes the two key bit sets 5 mated with key bit 4, and this two key bit overlaps and is movably set with the lockhole set 6 mated with key bit set 5 on 5 outer peripheral faces；Described spoon bar 13 one end is also movably set with a connector tip 7, and this connector tip 7 is mated with the connector tip set 8 being movably set in lockhole 2 one end, and described connector tip is overlapped and is additionally provided with a buckle 81 on 8 outer peripheral faces.

This utility model two key bit set 5, connector tip set 8, the interlude of lockhole 2, and key 1 enter lockhole 2 period and can rotate and synchronous axial system along with key 1.

When this utility model uses: key 1 is put into lockhole 2 until key bit 4 enters key bit set 5, some joint units 3 can deform accordingly along with the shape of lockhole 2, until mating with lockhole 2, this key bit 4 is corresponding with marble hole position on key bit set 5, after key inserts and puts in place, the height of key bit 4 coordinates corresponding with the length of pellet just, the pellet of key bit set 5 just can be ejected the pellet of lockhole 2, key bit set 5 is made to rotate, thus drive connector tip set 8 rotation, so that buckle 81 loosens, finally open lock.

The present embodiment is used for explaining that utility model of the present utility model is conceived, rather than the restriction to this utility model protection domain, all above-described embodiment does any unsubstantiality change, and belongs to protection domain of the present utility model.
