Description

An Improved Car Steering Wheel Lock

technical field

The invention belongs to locks, in particular to an improved automobile steering wheel lock.

Background technique

For preventing automobile from being stolen, automobile steering wheel lock is practical and convenient antitheft lockset commonly used, and the product of existing multiple different structures at present, no matter that kind of lock has its deficiency. Some of these locks have complex structures, some are inconvenient to use, some are easily damaged, and the anti-theft performance is poor, such as the existing T-shaped automobile steering wheel lock. The gap, it is easy to insert the tool into the gap to pick the lock. Therefore, be necessary to develop better automobile steering wheel lock.

Contents of the invention

The object of the present invention is to provide an improved automobile steering wheel lock with reasonable structure, convenient use and better anti-theft performance.

The solution of the present invention is: an improved automobile steering wheel lock, comprising a lock body and a buckle, the lock body is provided with: an outwardly extending stop member, a lock head, and a front cover matched with the outer ring of the steering wheel; The lock buckle is equipped with: a lock rod, an outer cover covering the lock rod, and a rear cover that matches the outer ring of the steering wheel; the lock rod of the lock buckle is inserted into the lock hole of the lock body along the direction of the stop part to slide and fit with the lock body, and the outer cover The cover is on the lock body to slide and cooperate with the lock body; the lock bar of the lock catch is provided with a ratchet to cooperate with the elastic lock pin controlled by the lock head in the lock body; the front cover and the rear cover can be matched correspondingly.

Further technical solutions are:

The front end of the locking rod is provided with a return spring.

The inner surfaces of the front cover and the rear cover are provided with gaskets.

The lock is provided with a horn pressing plate.

The lock of the present invention uses the lock body and the front cover and rear cover on the lock buckle to be fixed on the outer ring of the steering wheel of the car, and the lock is locked by the lock pin in the lock body and the lock rod in the lock buckle, so that the stop part is firmly positioned to limit the rotation of the steering wheel. Since the lock catch is equipped with an outer cover that matches the lock body, it can not only shield the lock rod for protection, but also eliminate the gap between the lock body and the lock catch contact end, and prevent the lock from being damaged by inserting tools into the gap. . The lock bar adopts ratchet teeth to cooperate with the elastic lock pin, so that when locked, the lock catch can only move towards the direction of closing with the lock body, and cannot retreat, which has the effect of getting more and more locked. When unlocking, the return spring can make the lock bar drive the lock catch to separate from the lock body automatically. The pads on the inner surfaces of the front cover and the back cover are used to adjust the inner diameter of the front cover and the back cover after they are combined, so as to adapt to steering wheel outer rings of different diameters. The horn pressing plate on the lock buckle can be pressed on the horn of the steering wheel when the lock is locked, and when someone manually locks, the horn pressing plate will press the horn to play an alarm function.

The lock of the present invention adopting the above-mentioned structure has the advantages of reasonable structure, convenient use, wide adaptability and better anti-theft performance.

The present invention will be further described below in conjunction with accompanying drawing.

Detailed ways

See Fig. 1-Fig. 3, the improved automobile steering wheel lock comprises a lock body 5 and a buckle 9, and a rod-shaped stop part 10 extending outward is fixed on the lock body 5, and a lock head 6 and an outer ring of the steering wheel are provided. 1 the front cover 3 matched; the lock bar 11 is fixed on the lock buckle 9, and the inverted U-shaped outer cover 4 covering the lock bar 11 is provided; the rear cover 2 matched with the steering wheel outer ring 1; the lock bar on the lock buckle 2 11 Insert into the lock hole of the lock body 5 along the direction of the stop part 10 to slide and fit with the lock body 5, and at the same time, the outer cover 4 is covered on the lock body 5, and the outer cover 4 is embedded into the lock body through the inward convex strips 401 arranged on both sides 5 The grooves 501 on both sides are slidingly matched with the lock body 5 (see Figure 4); the lock bar 11 of the lock catch 2 is provided with a ratchet 21 to cooperate with the elastic lock pin controlled by the lock head 6 in the lock body; the elastic lock Pin comprises lock pin 17 and is located at the return spring 18 of lock pin rear end, and lock pin 17 and return spring 18 are fixed in the assembly hole on the lock body 5 by cover 19, and lock pin 17 is provided with groove 20 and The shifting block 16 at the end of the lock cylinder in the lock head 6 matches, and the front end of the locking bar 11 fixes the limit baffle 13 with a screw 12, and sets the limit baffle 13 between the limit baffle 13 and the clamp 15 fixed in the stop part 10. There is a lock catch 9 return spring 14; the front cover 3 and the rear cover 2 correspond to each other, and when locked, they can fit together to wrap the outer ring of the steering wheel, the inner surfaces of the front cover and the rear cover are provided with a gasket 7, and the lock catch 9 is hinged There is a horn pressure plate 8 approximately perpendicular to the stopper 10 .

Use of the present invention, lock: the front cover 3 on the lock body 5 is covered on the outer ring 1 of the steering wheel of the automobile, and the stop part 10 is placed on the instrument panel of the driver's cab, and the lock catch 9 is pushed to be locked The back cover 2 of the lock body 5 is combined with the front cover 3 of the lock body 5 to wrap and hold the outer ring 1 of the steering wheel tightly, and at the same time press the horn pressure plate 8 on the horn; because the lock rod 11 on the lock buckle 9 passes through the ratchet on it 21 cooperates with the elastic lock pin controlled by the lock head 6 in the lock body, and can only move forward. The more firmly it is combined with the steering wheel, at this moment the stop part 10 is firmly positioned on the steering wheel, and the steering wheel cannot rotate arbitrarily under the obstruction of the instrument panel, so as to achieve the purpose of anti-theft; After the lock, the gap formed by the lock catch 9 and the lock body 5 at the ends of the joints of the front and rear covers 3 and 2 is covered by the outer cover 4, which can prevent the lock from being pried open by inserting a tool into the gap; Pressing plate 8 touches horn and plays alarming effect.
