Description
Technical field
The utility model relates to a kind of automobile-used locks such as bicycle, motorcycle, Moped Scooter, battery truck, tricycle that are used for, and specifically is a kind of U-type anti-theft lock for automobile.
Background technology
The U-type anti-theft lock for automobile of prior art is of a great variety, structure is different, simple in structure, the low price that have, but anti-theft effect and safety are not ideal, end as the end at present general on the market cross locking body two ends and U-shape lock bar is hinged, the U-type anti-theft lock for automobile of the other end at cross locking body two ends and the other end of U-shape lock bar locking, the relative exposure of lock core of its hinged place and tapered end pried open by the people easily or imitated bitting and open; And for example a kind of U-shape lock bar commonly used inserts the U-type anti-theft lock for automobile in the lock body of aluminum, and its aluminum lock body is opened with destructive means such as hammerings easily; Have as disclosed multiple U-type anti-theft lock for automobile on the China national intellectual property board web, its anti-theft effect is better, safety is stronger, but structure is complicated, operates more loaded down with trivial detailsly, cost is higher.And, the anti-theft lock for vehicle of above prior art, its tapered end and the key that matches with it are still S type, cross, blossom type, the general model in market such as half-moon-shaped, the personnel that they still can not be stopped except that manufacturer prepare key, so, still exist its key by imitative joining and the potential safety hazard that quilt cover is unblanked.
The utility model content
The technical problems to be solved in the utility model is, overcomes the shortcoming of above prior art, provides a kind of both simple in structure, easy to operate, cost is lower, can't imitate bitting again and overlaps and unblank, have the desirable anti-theft effect and the U-type anti-theft lock for automobile of safety.
Technical solution of the present utility model is, a kind of U-type anti-theft lock for automobile with following structure is provided, comprise steel and through heat treated U-shape lock bar and be provided with ccontaining U-shape lock bar two free-ended latch arm hole lock body and place tapered end in the tapered end hole of lock body, two free-ended inboards of described U-shape lock bar have locking recessed; Described lock body is that cast steel is made; It is the notice of authorization number ball lock head with axial rotary ball hole for the applicant's of CN2830584Y patent disclosure formerly that described tapered end adopts the ball lock head with axial rotary ball hole, is connected for non-disconnectable formula between the ball lock head hole of ball lock head and lock body; The tail end of ball lock head is fixedly connected with swing arm, and the device that can stir left and right lock is arranged in the swing arm 4; The left and right lock cylinder aperture of ccontaining left and right lock is communicated with ball lock head hole and left and right latch arm hole, and the axis of lock cylinder aperture is vertical mutually with the axis in ball lock head hole; The left and right lock that is positioned at lock cylinder aperture is the little stairstepping of outer imperial palace, the recessed shape of the locking of the shape on its major part top and U-shape lock bar matches, be with back-moving spring on its little bar, the two ends of back-moving spring are supported respectively to the step of the inner face of major part and lock Kongzui inner end.
After adopting above structure, the utility model U-type anti-theft lock for automobile compared with prior art has the following advantages:
1, since the utility model U-type anti-theft lock for automobile adopted very succinct, stir structure and latch-up structure reliably, promptly lock with behind the key rotation tapered end U-shape lock bar being inserted lock body, promptly open with extracting the U-shape lock bar out behind the key rotation tapered end, so, its structure is very simple, operation is very easy, and cost is lower, low price.
2, because the lock body of the utility model U-type anti-theft lock for automobile is the cast steel making, the U-shape lock bar is a steel material and through heat treatment, be connected for non-disconnectable formula between the ball lock head hole of tapered end and lock body, so, even taking destructive meanss of destruction such as sled, hammering also can't open lock, its anti-theft effect is very desirable, and its safety is very strong.
3, because the ball lock head that the utility model U-type anti-theft lock for automobile adopts the U-type anti-theft lock for automobile of prior art never to adopt with axial rotary ball hole, from seeing the internal construction of the lock core of its tapered end in appearance, the user who buys this lock needs configuration key to get in touch with original production producer, process configuration by original production producer according to the computer numbering of original key, so, substantially the potential safety hazard of having stopped imitative bitting and having unblanked guarantees that the user has the very high sense of security.
