Abstract

The utility model discloses a steering lock with a key mistaken-pulling preventing structure, and aims at providing an internal mechanism of the steering lock, which can prevent a key from being pulled out by mistake. The technical scheme has the key points that the steering lock comprises a steering lock body, wherein the steering lock body is internally provided with a lock core which is provided with a lock hole; the lock core and the steering lock body are in sliding arrangement; the lock core is provided with a return piece for returning of the lock core; a stopping block is arranged between the lock core and the steering lock body; and the lock core is provided with a lock core limiting boss, which is used for separating from the stopping block when the lock core slides axially and inwards and limiting the stopping block when the lock core slides axially and outwards. The steering lock is simple in structure and obvious in mistaken-pulling preventing effect.

Description

The steering lock of band key false pull prevention structure

Technical field

The utility model relates to a kind of steering lock, and more particularly, it relates to a kind of steering lock with key false pull prevention structure.

Background technology

The steering lock of steering lock full name band ignition switch is a multi-gear switch, needs could handle it with corresponding key, and steering lock is generally used for the control point ignition circuit, appliance circuit, motor field circuit, starting circuit and ancillary apparatus circuit etc.Traditional steering lock generally includes the steering lock body, and the steering lock body is provided with the lockhole suitable with key, when key cooperates with lockhole, rotates lockhole, thereby realizes the conversion of lock core gear, and when lock core was rotated the locking shelves, key just was pulled out.But so simple structure setting makes steering lock exist key to be pulled out or vehicle ' vibration key comes off and causes locked steering wheel problem by mistake, and it is used inconvenience and has potential safety hazard.

Summary of the invention

To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of key that can effectively prevent from steering lock key false pull prevention mechanism that the steering lock mistake is extracted.

For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of steering lock with key false pull prevention structure; Comprise the steering lock body, said steering lock body is built-in with lock core, and lock core is provided with lockhole; Said lock core and steering lock body slide and are provided with; Lock core is provided with the return spare that supplies its return, is provided with block between lock core and the steering lock body, lock core be provided with lock core shaft when inside slip and block disengaging and lock core shaft when outside slip and the spacing lock core positive stop lug boss of block.

Through adopting technique scheme, when making that lock core positive stop lug boss and block are spacing and cooperating, can't it be extracted key; As to extract key; Lock core is axially inwardly pressed along it, and lock core positive stop lug boss and block just can break away from, then rotational lock core; Extract key, just can prevent effectively that through the lock core positive stop lug boss is set simply key from being extracted by mistake.

The utility model further is set to: said return spare is set to compress spring, and said compression spring is arranged on the relative lockhole other end of lock core.

Through adopting technique scheme, the return performance of compression spring is good, easy to use.

The utility model further is set to: said block and steering lock body are connected with the block return spring that supplies the block return.

Through adopting technique scheme, make that the block return spring can effectively help its return, further improves the effect of the false pull prevention of mechanism when being moved in the block course of work, prevent simultaneously that vehicle ' vibration key from coming off to cause the potential safety hazard of locked direction.

Description of drawings

Fig. 1 is the structural representation of the steering lock embodiment of the utility model band key false pull prevention structure;

Fig. 2 is the structural representation when lock core positive stop lug boss and block break away among the steering lock embodiment of the utility model band key false pull prevention structure.

The specific embodiment

Referring to figs. 1 through Fig. 2 the steering lock embodiment of the utility model band key false pull prevention structure is further specified.

A kind of steering lock with key false pull prevention structure; Comprise steering lock body 1; Said steering lock body 1 is built-in with lock core 11, and lock core 11 is provided with lockhole 111, and said lock core 11 slides with steering lock body 1 and is provided with; Lock core 11 is provided with the return spare 113 that supplies its return; Said return spare 113 is set to compress spring, and said compression spring is arranged on lock core 11 relative lockhole 111 other ends, is provided with block 12 between lock core 11 and the steering lock body 1; Said block 12 is connected with the block return spring 121 that supplies block 12 returns with steering lock body 1, breaks away from block 12 when lock core 11 is provided with lock core 11 and axially inwardly slides and lock core 11 axially outwards during slip and the spacing lock core positive stop lug boss 112 of block 12.

Shown in accompanying drawing 1, lock core positive stop lug boss 112 is blocked by link stopper 12, and key 2 rotates less than locking shelves when coming with lockhole 111 dislocation (be key 2), prevents that key 2 from not extracting in locking shelves mistiming; Shown in accompanying drawing 2, after key 2 advanced lock core 11, lock core positive stop lug boss 112 was crossed link stopper 12, at this moment arrived the locking shelves with key 2 rotatable lock cores 11, and key 2 can be extracted.
