Description

Automobile, motorcycle, bicycle ground fixation anti-theft lock

[technical field] the utility model relates to a kind of automobile, motorcycle, bicycle ground fixation anti-theft lock, belongs to mechanical automatic control technical field of burglary prevention.

[background technology] automobile, motorcycle, bicycle generally all are furnished with theftproof lock respectively, in case stolen, but present various theftproof locks are to do some technological improvements on the unlocking technique of lockset and on the anti-mechanical damage of the overstriking of lock body apparent size mostly.Also have the following disadvantages from the application of lock: the one, lock core exposes, anti-technology unlocking and mechanical damage lock core ability; The 2nd, the anti-stolen ability of car load, and the phenomenon of stolen burglar was very general after car load moved at present; The 3rd, the inconvenience the when overstriking of apparent size causes carrying with switch.

[summary of the invention] is for overcoming the above-mentioned deficiency of existing lock; the ground fixation anti-theft lock that the utility model provides a kind of automobile, motor, bicycle to use; to improve the safety and the reliability of theftproof lock; burglary car person can't be opened also can't wholely move back robber's car, thereby protection car owner's interests are not suffered a loss.

For solving its technical problem, the technical solution adopted in the utility model is: design one by base, tapered end, interlocking mechanism, retainer spring, lock core, the automobile that lock pin and ground bolt are formed, motorcycle, the ground fixation anti-theft lock that bicycle is general, be characterized in: 1. the bottom of base is provided with the ground bolt, so that be fixed on cement floor or the fixed support, the top of base is provided with a semicircular space, on two semicircle other seat walls, be provided with a groove, respectively be fixed with the movable tapered end of a circular arc in the groove by lock pin, be connected with a retainer spring between the top rear wall of tapered end and the base, the bottom of tapered end is provided with the circular groove of the band lock groove that matches with lock core, is provided with the shallow circular groove for the rotation lock of lock core locking plate in the outside of circular groove; The lower end of two tapered ends is equipped with a slotted eye for the spring catch advance and retreat of interlocking mechanism, is provided with an interlocking mechanism in the bottom of base middle part two tapered ends, is provided with a built-in lock core hole on the base body of interlocking spring pin one end, is provided with lock core in the lock core hole.2. described interlocking mechanism is an interlocking spring pin, and an end of interlocking spring pin is spherical, and the other end is a tip, is provided with spring between the two ends, and when the lock banking stop of lock core pinned, the other end that can promote spring catch inserted in the slotted eye of another tapered end bottom.3. described lock core is withdrawable lock core, the external diameter of lock core is 26.99～26.05mm, the top of lock core is provided with the axial locking direct selling of semicolumn that the band diameter is 7.99～7.95mm, lock core turning cylinder centre bore is a cross, the turning cylinder afterbody is provided with lock banking stop, and the lock banking stop afterbody is identical with locking direct selling radial dimension.4. described built-in lock core hole, the diameter dimension in its hole are 27.01～27.05mm, and the top in hole is provided with the axial locking straight trough of semicolumn that diameter is 8.01～8.05mm.

Operating principle of the present utility model is:

When not locking, tapered end is in open configuration under the effect of retainer spring, when wheel enters the tapered end bottom is pressed down, and movable tapered end rotates around lock pin, and movable tapered end top fastens wheel.Retainer spring is positioned at the lock position with tapered end, in order to guarantee that tapered end also is fixed by another tapered end of lock core locking back on one side, an interlocking spring pin is housed in the bottom of two tapered ends, after wheel enters bottom tub, the lock core of carrying is inserted in the lockhole, and the lock core of insertion pushes spring catch in the slotted eye of another tapered end bottom.Rotate lock banking stop, in lock body, extract lock core card out key, finish locking.When picking up the car key is inserted lock core hole, the lock banking stop of rotational lock core is extracted lock core out in lock body, and after wheel withdrawed from, tapered end returned to open configuration under the effect of retainer spring.

The beneficial effects of the utility model are: 1. be fixed as one by ground bolt and cement floor owing to base of the present utility model, carry out technical finesse or destroy lockset by force after making the car stealer car load can't be moved to the elsewhere, because the base and the tapered end of lock body are general standard products, can be installed to again such as public places such as community, large supermarket, school, streets.As long as the car owner with on separately lock core and key, just can relieved everywhere parking, not only convenient but also effective respectively the stop parking order in place of standard; 2. since base install and ground inclination, and lock core hole is built-in on base, the built-in lock core hole of this inclination allows and uses unlocking technique to steal car and can't see and not have the operating space clearly with the car stealer of mechanical damage lock core; 3. because the tapered end on the base is to advance/go out automatic fastening or open with wheel, make lock car person convenient; 4. lock body base of the present utility model and tapered end, as long as selection intensity is good, hardness is high material or also heat-treat just can allow the car stealer can't carry out mechanical damage by force, generally the thief more can't go smoothly, can increase safety and the reliability that parks cars, reduce car owner's unnecessary loss.
