Abstract

The utility model discloses an anti-theft lock of an automobile tool case. The anti-theft lock of the automobile tool case comprises a lock seat, a lock body, an unlocking poking block and a set bar, wherein the lock body and the unlocking poking block are arranged on the lock seat next to each other. The lock body comprises a casing body and a lock cylinder, a latch hook and a lock catch. The latch hook and the lock catch lock are matched with the tool case in a dead lock mode. The set bar moves along with the lock cylinder. The unlocking poking block is reset through a reset torsion spring. One end of the reset torsion spring is fixed on the lock seat and the other end of the reset torsion spring is pressed under the set bar. The lock catch is reset through a revolving shaft which is fixed on the lock seat and the reset torsion spring. A poking rod which is matched with the set bar is arranged on the unlocking poking block. When the anti-theft lock is in the dead lock state, the lock catch is pressed on the set bar which is arranged on one side of the poking rod. The anti-theft lock of the automobile tool case is simple in structure, low in requirement for precision and high in safety and can be widely applied to the field of locks of automobile tool cases. The set bar is arranged behind the unlocking poking block and the lock body and invisible.

Description

A kind of automobile toolbox theftproof lock

Technical field

The utility model relates to a kind of theftproof lock, relates in particular to a kind of automobile toolbox theftproof lock.

Background technology

For conveniently taking instrument, general vehicle tool case all is placed on the automobile chassis or the similar place of exposing, therefore an anti-theft tool case lock just need to be set up in this tool box, number be 200410047331.7 to disclose a kind of tool box breech lock such as Chinese patent application, have be installed on the shell and with the handle of catch bar mechanical connection, the mounting board and unclamp the impacting pin of cooperation in order to a series of connections aprowl are set.Separate on the open position and handle is pulled in pivoting action and when deviating from shell, catch bar just rotates the revolution trip rod when the core member at first is rotated.So the revolution trip rod just rotates the member that is rotatably connected out from its locked position with the rotary locking bar, allow on the rotary locking bar biasing spring from its mounting board position rotation out.This utility model complex structure, component and matching requirements precision are high, and cost of production is high.

The utility model content

The purpose of this utility model provides a kind of automobile toolbox theftproof lock, and it is complicated to solve the tool box anti-theft lock structure, and required precision is high, the problem that cost of production is high.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of automobile toolbox theftproof lock, comprise lock, be arranged side by side lock body on lock and release shifting block and cooperate locked latch hook and snap close with the tool box, lock body comprises housing and lock core, also be provided with by lock core drive and with the locking bolt of snap fit, make the reduction torsion spring of release shifting block return, reduction torsion spring one end is fixed on the lock, and the other end is pressed in the below of locking bolt; Described snap close cooperates installation with rotating shaft and return torsion spring on being fixed on lock; Be provided with the driving lever that cooperates with locking bolt on the described release shifting block.

Preferably, the end of described lock core is provided with eccentric boss, and locking bolt is fixed on the eccentric boss.

Preferably, described return torsion spring two ends are fixed in the rotating shaft, and intermediate sleeve is pressed on the snap close.

Be the return-stroke of control shifting block, be provided with the baffle plate of restriction driving lever stroke on the described lock.

The beneficial effects of the utility model: by cooperating of locking bolt and shifting block, the unlocking function of unblanking of implementation tool case lock, locking bolt and driving lever simple in structure, precision prescribed is low, and is easily manufactured, and locking bolt does not leak outside safety and reliability.Locking bolt is fixed on eccentric boss, and the rotational transform of lock core is become the transverse shifting of locking bolt, cooperates driving lever to realize release, and is simple in structure.Described baffle plate can be controlled the return-stroke of release shifting block when return.

Below in conjunction with drawings and Examples, the utility model is described in further detail.
