Abstract

This utility model is a twin-lock body safety lock. One end of the key cylinder of the main lock body is fixed on the assistant lock body, the corresponding assistant lock body of the main lock body sets a hole, one end of the seal board of the hole set in the inside of the hole connects to the bolt of the assistant lock body, the other end of an axle supports the structure of the assistant lock body, the fulcrum shaft has the same axial line with the swinging axle of the swinging bolt. The assistant lock body of the twin-lock body safety lock controls the switching of the seal hole board with its key cylinder, only when the seal hole board is open, can use the key to open the key cylinder of the main lock body. The board has no a opening hole whose shape is as same as the key of the key cylinder of the common key cylinder prevent-drill cover so that it is difficult to be broken by prying. Between the twin-lock body of this safety lock has no the interacted component so that the structure is simple. This utility model has simple structure, small capacity and good effect of safety. Is can be used on various ball locks especially the lock for guard against theft of the bike, the electric power driven bike and the motorbike.

Description

Twin-lock body safety lock

Technical field

The utility model belongs to lockset, particularly relates to a kind of twin-lock body safety lock.

Background technology

In the known technology, for increasing the security protection performance of lock, the anti-drilling lid that is supported in lock body in the plug face setting is adopted by many locksets, particularly bicycle or lock for motorcycle.This anti-drilling lid is supported in the lock body annular groove, can rotate along its plane, anti-drillingly is covered with, and the perforate that with it overlap consistent with the lock core key hole shape.Above-mentioned anti-drilling lid has certain security protection effect, takes place but still can not prevent to prize the devious conduct of dialling anti-drilling lid.

The utility model of notification number CN2751115Y " double lock device " disclose a kind of can prevent improper release behavior effectively have the technical scheme of main and auxiliary lock by same housing, the last lock construction element energy move left and right of main lock is to finish lock and unlock, auxilliary lockset has the driving mechanism that acts on the main limiting member of locking and this limiting member, limiting member comprises and has two cams that can overlap notch part, drive mechanism first cam.Its driving mechanism can be a spring.Should " double lock device " be to be the security protection means to limit auxilliary lock time that the back opens main lock of unblanking, after unblanking, in the time that machinery is set, do not open by promptly auxilliary lock main lock, then the notch part of two cams no longer overlaps, and the last lock construction element of main lock then can not be finished the release action.Above-mentioned " double lock device " though the scheme novelty, structure is complicated.

Summary of the invention

The utility model is that the protection effect that above-mentioned anti-drilling lid and " double lock device " exist is respectively owed reliably in order to solve, structure is than the complicated technology problem, and a kind of simple in structure, twin-lock body safety lock that security protection is reliable for effect is provided.

The utility model is taked following technical scheme for solving anti-drilling lid with the above-mentioned technical problem that " double lock device " exists respectively: the lock core body one end vertical fixing of main lock body is in auxiliary lock body, the pairing auxiliary lock body of the lock core body of main lock body is provided with via hole, the via hole shrouding one end that is arranged at the via hole inboard engages with the swing dead bolt of auxiliary lock body, other end axle is supported in the auxiliary lock body structural member, its fulcrum and the swinging center coaxial line of swinging dead bolt.

The utility model can also be taked following technical measures:

Described main lock body lock core body is the elastic shrinkage lock core body.

Described via hole shrouding is provided with the arcwall face with auxiliary lock body arc inner wall sliding fit.

Its lock core body surface of described auxiliary lock body is provided with the anti-drilling lid that is supported in auxiliary lock body.

The beneficial effects of the utility model and advantage are: the switching of its lock core control via hole shrouding of the auxiliary lock body of this twin-lock body safety lock, and have only and open the lock core that the via hole shrouding could pass through key operated main lock body.And that the via hole shrouding does not have at the via hole place that known lock core drilling-preventing lid is provided with is consistent with the lock core key hole shape, and the perforate that overlaps with it, therefore is difficult to sled and dials and go to pot.There is not the member of restriction mutually between the twin-lock body of intrinsic safety full lock, therefore relatively simple for structure.The utlity model has outstanding advantage relatively simple for structure, that volume is little, security protection is reliable for effect, be applicable to that various cylinder locks use especially bicycle, electric assisted bicycle and anti-theft lock for motorcycle use.
