Abstract

The utility model provides an enclosed lock for motor vehicles for the technical field of vehicle fittings. The utility model is mainly characterized in that an integrative lock body is sheathed on vehicle axles and chuck wheels; the chuck wheels are provided with bullet holes; bullets locks the chuck wheels, making the lock body and vehicle bodies fixed; the space between the lock body, the vehicle bodies, and the wheels is quite small; the lock body has little possibility of damage. When a lock liner is damaged, the locked bullets can not be opened because gears can not be toggled, and the wheels are still can not be rotated. Because the bullets are locked in driving and locked in driven, the bullets are not directly toggled or other parts of the lock body are not damaged, the lock can not be opened. Compared with other locksets which take the opening type in driving, the utility model has obvious advantages.

Description

Closed motor vehicle lock

The utility model belongs to the vehicle body fittings technical field, is a kind of closed motor vehicle lock.

The self-propelled vehicle kind of operation is a lot of at present, stolen in order to prevent self-propelled vehicle, its protection mode also has a lot, mainly comprise lock direction, locking wheel disk and warning device etc. is installed, but thief has formed cover actv. theft means and a stealing tool, and existing anti-theft technique has reached the purpose of safety precaution.

The purpose of this utility model is a kind of closed motor vehicle lock of design.

Technical solution adopted in the utility model is that a pedestal baffle plate is set, on basic unit's baffle plate, lock gall is set, lock gall is connected with a driving gear, other is provided with a working basic stand, working basic stand is connected with the pedestal baffle plate, an elastic component is set on working basic stand at least, bullet and push piece movement slots, back and forth push piece is installed on the hollow shaft on the pedestal baffle plate, and back and forth push piece one side is provided with wedge shape and pushes away tooth, and opposite side is provided with the outside thread hollow shaft, on the thread hollow axle driven gear is set outside, the driven gear endoporus establishes screw thread and the outside thread hollow shaft is connected, and driven gear outer tooth and driving gear are connected with a joggle, thereby constitutes the closed motor vehicle lock of the utility model.

When the utility model uses, on the vehicle card plate wheel, offer the bullet hole, be placed on chuck wheel and the axletree through working basic stand, the pedestal baffle plate is fixed on the car body, with key turns lock gall and driving gear, thereby drive driven gear, the rotation of driven gear makes reciprocal push piece cross travel, pushes away tooth then and promotes bullet and make vertical displacement, bullet is snapped in or shifts out bullet hole on the chuck wheel, thereby locking or release chuck wheel reach the purpose of locking car; Very little because of the gap of pedestal baffle plate and working basic stand and car body and wheel, be difficult for destroyedly, both made lock gall destroyed, back and forth push piece can not be moved by thread lock, also can't open chuck wheel, compare with prior art and to have tangible advantage, simultaneously, also provide a kind of later-model anti-joyride device.

Reach example in conjunction with the accompanying drawings and further introduce architectural feature of the present utility model.

Fig. 1 is a general assembly structural representation of the present utility model.
