Description

Steering wheel lock

Technical Field

The utility model relates to a lockset, in particular to a steering wheel lock.

Background

With the improvement of living standard, most people go out to vehicles, but the theft rate of the vehicles is gradually increased, so that the anti-theft locks for various vehicles are also used for asking the market.

Among these anti-theft locks for vehicles, steering wheel locks are the most common. Steering wheel locks, as the name suggests, are locks used to deadlock steering wheels, making steering wheels difficult to turn. Since most vehicles are steered by a steering wheel, once the steering wheel is fixed, thieves cannot smoothly steer the steering wheel and drive the vehicle away even if they can invade and start the vehicle. Therefore, such steering wheel locks can play a role in preventing theft.

With the advancement of social science and technology, the means of thieves are gradually transformed into technical and professional means. Theft personnel know that the anti-theft function of the existing steering wheel lock is derived from a lock cylinder on the steering wheel lock, so that corresponding crime tools can be carried by aiming at the lock cylinder before theft. In addition, the lock holes of the existing lock cylinder are exposed, so that technical thieves can easily pry the lock cylinder to steal. Thus, the existing steering wheel lock structure cannot be suitable for future market demands.

Disclosure of Invention

The utility model aims to provide a steering wheel lock with higher safety coefficient.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a steering wheel lock, includes the lock body, the activity sets up in the tapered end of lock body, forms the catching groove between lock body and tapered end and installs in the lock core and the lock handle of lock body, it has the baffle ring around in lock core operation face periphery to extend on the lock body, is equipped with the hidden dog of sealed lock core operation face in the baffle ring, is equipped with locking Assembly between hidden dog and the baffle ring, be equipped with the hidden control assembly that cooperation magnet is used for controlling locking Assembly in the hidden dog.

In addition, the structure of the hidden stop block is different from the conventional common anti-theft structure on the market, so that a thief is difficult to steal and cannot quickly steal through a portable common crime tool, and the safety coefficient of the steering wheel lock is higher. When the hidden check block is to be opened, the magnet is only required to be close to the hidden control assembly to control the locking assembly to unlock through the hidden control assembly, so that the hidden check block is opened, and the steering wheel lock can be opened through a lock hole on the lock cylinder operation surface, thereby realizing double insurance.

Further provided is that: the locking assembly comprises a plurality of locking blocks movably arranged on the hidden stop block and locking grooves formed on the inner peripheral wall of the baffle ring and corresponding to the locking blocks, the locking blocks are circumferentially distributed around the outer peripheral wall of the hidden stop block, and the locking grooves are circumferentially arranged around the baffle ring to form a ring shape.

Through adopting above-mentioned technical scheme, the locking piece that the activity set up gets into the locking groove and constitutes the spacing of hiding the dog, reaches locking purpose, simple structure, low cost.

Further provided is that: including forming in hiding the dog and supplying the installation cavity of control assembly installation and forming in hiding the dog and corresponding every locking piece and supplying its movable passageway of activity, every the movable passageway all communicates locking groove and installation cavity, hide a plurality of locking pieces of control assembly synchronous control.

By adopting the technical scheme, the locking structure is more stable and the control is more convenient.

Further provided is that: the hidden control assembly comprises a control iron block which is movably arranged in the mounting cavity and moves towards the locking blocks in a reciprocating mode and a spring which drives the control iron block to move towards the locking blocks, and a limiting assembly which limits dislocation of the locking blocks is formed between the mounting cavity and the control iron block.

By adopting the technical scheme, the spring drives the control iron block to move towards the locking block so as to drive the locking block to enter the locking groove to form locking, when the locking component is to be controlled to unlock, the magnet is close to the hidden stop block, the magnet adsorbs the control iron block to move back to the spring and compress the spring, so that the locking block leaves the locking groove, and the control iron block and the hidden stop block can be taken out of the baffle ring together under the action of the magnet, so that the operation is simple and convenient; the control mode is hidden, and the safety coefficient is higher. The adsorption force of the magnet adsorption control iron block is larger than the elasticity of the spring, and the movable position of the locking block is limited by the limiting component, so that structural interference caused by dislocation is avoided.

Further provided is that: the limiting assembly comprises a limiting block fixedly arranged in the mounting cavity and located at the central positions of the locking blocks and a limiting groove formed in the control iron block and used for the limiting block to enter.

Through adopting above-mentioned technical scheme, the setting of stopper restricts the movable range of locking piece, avoids causing the interference on the structure to the normal activity of control iron plate is guaranteed to the spacing groove that the cooperation set up, avoids causing the interference.

Further provided is that: when the steering wheel lock is secured to the steering wheel, the operating face of the lock cylinder is set up upwards and the spring is located above the control iron block.

Through adopting above-mentioned technical scheme, this kind of setting mode convenient operation, and cooperation spring makes locking component constitute the locking with the weight of control iron plate, and intensity is higher.

Further provided is that: the locking block is spherical, and a guiding inclined plane for guiding the locking block to move towards the locking groove is formed on the control iron block.

By adopting the technical scheme, the guide inclined plane is matched with the spherical locking block, so that the moving control iron block can better drive the locking block to enter the locking groove.

In summary, the utility model has the following beneficial effects: the utility model realizes double insurance by arranging the hidden stop block to be matched with the lock cylinder, and the opening mode of the hidden stop block is hidden, so that the opening mode of the hidden stop block is difficult to be directly observed from the outside, and the safety coefficient is higher.
