Abstract
An anti-theft lock for vehicle is provided, which comprises a round pipe arc lock pipe, a lock beam, a locking head shell, a lock body, a pressure spring, a defending pipe and a handle. The utility model is characterized in that: a diameter-enlarged arc lock bolt is fixedly connected at front end of the lock beam; the lock beam and the arc lock bolt are positioned through pins and is fixedly connected through pressing; besides, the defending pipe fixedly connected with the rear end of the lock pin is provided with two symmetrical top spring grooves. The utility model, by adopting special connecting structure, perfectly connecting the lock pin and the diameter-enlarged arc lock bolts into an integrated sectional steel, so as to enable the integrated lock beam firmer, anti-theft and durable.; meanwhile, the groove designed on the defending pipe avoids the defects as the easy-sliding-down lock bolt and the insufficient locking; therefore, the utility model has the advantages of easy operation, simple manufacture technics and flexible and convenient utilization.
Description
Technical field
The utility model relates to a kind of anti-theft lock for vehicle, particularly a kind of pipe theftproof lock.
Background technology
Common automobile-used pipe theftproof lock, it comprises lock body, lock bridge, lock pipe etc., the anti-theft lock for vehicle of this structure, because lock bridge is thin, the interstitial site between lock bridge and the lock pipe is too many, the robber easily cuts, easily saws, easily prizes, so its theftproof performance is poor.So there is the designer to adopt the diameter that increases lock bridge to strengthen the firm property of lock bridge, but the difficulty that is difficult to overcome can appear during production and processing, for example: the arch locking bolt that increases is inserted in the arch lock pipe, its technology manufacture view is difficult to realize on the one hand, on the other hand, even if can realize, bring damage also for during assembling lock pipe, lock bridge.
Goal of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of anti-theft lock for vehicle is provided, and it has improved the structure of the whole lock bridge in the lock pipe on the basis of original pipe anti-theft vehicle lock, make it have more theftproof and practicality.
The utility model comprises arch hollow lock pipe, tapered end shell, lock bridge, lock body, compression spring, and the affixed arcuation locking bolt of lock bridge front end, is nested with at the protecting tube of lock bridge rear end and handle etc., it is characterized in that arcuation locking bolt and lock bridge fixing position are penetrated with pin; Protecting tube is provided with top spring groove.
Above-mentioned arcuation locking bolt and lock bridge connect through the punching press circle.
Above-mentioned arcuation locking bolt and lock bridge are affixed through striking out a hexagon.
Above-mentioned protecting tube forms two top spring grooves of symmetry through punching press.
The end of above-mentioned arch hollow lock pipe is provided with a locking bolt return groove.
The utility model is on the basis that does not change original anti-theft lock structure, improved the structure of whole lock bridge, the arcuation locking bolt of the affixed dilated diameter of lock bridge front end increases exponentially the cross section of its locked position of coupler, strengthened the stiffness of lock, simultaneously its handling ease, unlikely damage lock pipe and lock bridge.The protecting tube that is nested with of lock bridge rear end forms top spring inner groovy through punching press in addition, has reduced the space between lock pipe and the lock bridge, prevent simultaneously that locking bolt from gliding and locking after the locking bolt return, make it more firm, more firm, and manufacture craft is simpler.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further described:
Structural representation when accompanying drawing 1 is the utility model locking;
Accompanying drawing 2 is the utility model structural representations when unblanking;
Accompanying drawing 3 is the whole lock bridge structural representations of the utility model;
Accompanying drawing 4 is A-A sectional views of accompanying drawing 3;
Accompanying drawing 5 is B-B sectional views of accompanying drawing 3.
The specific embodiment
Shown in accompanying drawing 1, accompanying drawing 2, the utility model is made up of compression spring 1, lining 2, tapered end shell 3, lock body 4, hollow lock pipe 5, lock bridge 6, lock ear 7, arcuation locking bolt 10, handle 11, protective jacket 12 and big lock ear 14, its arcuation locking bolt 10 runs through pin 9 with lock bridge 6 junctions, through striking out the hexagonal build, affixed state as shown in Figure 4 again.Adopt this built-in structure, not only can select larger-diameter arcuation locking bolt 10, and its fixing position is firm, no solder joint, has not only strengthened the stiffness of whole locking bolt, and have more anti-sled, anti-theft effect.
In conjunction with the accompanying drawings 3, shown in the accompanying drawing 5, form the top spring groove 121 of two symmetries on the protecting tube 12 of the present utility model through punching press, being provided with of this groove 121 reduced the space position of lock bridge 6 with lock pipe 5, and again as the gear of compression spring 1, prop up compression spring 1 and needn't increase stop block in addition, not only reduced parts but also saved operation; After simultaneously lock is installed, when car travels, can control effectively that locking bolt glides, vehicle spoke is stuck, thereby avoids people, car casualty accident on uneven road surface; After also having played locking, prevent the possibility of locking bolt return.
