The bullet lock head is unreleasably connected with bullet lock head hole (32) of the lock body (3); back end (21) of the bullet lock head is immovably connected with a swinging arm (4) which is provided with a device capable of pulling left (up)-right (down) column (55) and driving big head (51) of the left-right lock column to over spring force of return spring (53) and furling to the direction of bullet lock head hole (32) along lock column hole (33). Structure of the vehicular U-shaped theft-proof lock is simple, operation is easy, cost is relatively low, and it is can not be unlocked by imitated key to fit the lock, which has a perfect theft-proof effect and security.
Description
Technical field
The present invention relates to a kind of automobile-used locks such as bicycle, motorcycle, Moped Scooter, battery truck, tricycle that are used for, 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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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 ends of described U-shape lock bar have locking recessed; Described lock body is that cast steel is made; 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; 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 tapered end 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 of its major part outer end 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; Have the device that can stir left and right lock tail end to refer in the described swing arm, two circumferential recess of swing arm can offset with the reversed column on the left and right lock tail end that stretches into bottom, ball lock head hole and join; The described tail end that stretches into the left and right lock of bottom, ball lock head hole is shaped as the circular arc piece roughly the same with the ball lock head shape of hole wall, with the circular arc piece be one whole and be located at the end of circular arc piece to the reversed column of lower convexity, the circular arc piece is positioned at the top of swing arm; The circumferential recess of described swing arm can offset with reversed column and join, and the reversed column of pointing to lower convexity is positioned at the inboard of swing arm circumferential recess, and the axis of the mounting hole of a center line of two reversed columns and swing arm is on a line.
After adopting above structure, U-type anti-theft lock for automobile of the present invention compared with prior art has following remarkable advantage and beneficial effect:
1, since U-type anti-theft lock for automobile of the present invention 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 U-type anti-theft lock for automobile of the present invention 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 U-type anti-theft lock for automobile of the present invention 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.
