Description
Affiliated technical field
The utility model relates to a kind of vehicle anti-theft lockset, the antitheft Band-type brake lock that particularly combines with band-type brake and make it not only have the brake sticking brake function but also have the lock function.
Background technology
Current social bicycle has become the indispensable vehicle of people, and it is quite general to have many bicycles in the family, the stolen problem of giving prominence to the most in the social security work that become of a large amount of bicycles.Bicycle lock mostly is crab claw lock, chain lock etc. greatly both at home and abroad at present, wherein the structure of crab claw lock comprises lock shell, locking bolt, handle, spring lock etc., locking bolt can move in the croze in the car shell, the bayonet lock that has draw-in groove to be ined succession by the lock core end of spring lock on it blocks, thereby realizes the purpose of switch locking bolt.Because this body structure of bicycle lock is insecure, principle of design falls behind, and is easy to be pried open.Steel cable lock, chain lock are also easily by pinch off.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, and a kind of antitheft Band-type brake lock that directly combines with band-type brake is provided.
The purpose of this utility model is finished by following technical solution; Described Band-type brake lock comprises the brake drum that is inserted in rear axle one side, this brake drum is connected on the reel of back, at the inboard of brake drum welding gear ring, there is the brake shell in the outside, also has brake band in the brake shell, brake band is connected on the brake crank by stay cord, described Band-type brake lock is characterized in that it also comprises slide block, carriage, carriage rivet, spring, flexible tapered end group, steel wire card, slide block is placed in the carriage, carriage is riveted on the lock shell plane, the tapered end group is installed on band-type brake one side, and the core rod is linked to each other with slide block by spring.
Core of the present utility model is: locking mechanism cheaply rational in infrastructure is combined with band-type brake.This combination is to realize by the transmission between tapered end, slide block, gear ring.Principle of work of the present utility model is: when the lock core rod moves inward in the external force driving tapered end group, the spring that is connected between lock core rod and slide block is compressed, be that the lock core rod slides to gear ring by spring promotion slide block, the lock core rod moves to certain position and will be blocked by the tapered end pin, slide block is subjected to spring force always and slides to gear ring in this process, enter teeth groove up to slide block, Band-type brake lock reaches locked state.When using key rotation lock core, make it break away from pin, at this moment lock core outwards moves under the effect of retracing spring power in lock, and lock core is lived slide block by the steel wire grab simultaneously, realizes that slide block separates with gear ring, and promptly Band-type brake lock reaches open mode.
This use is compared with prior art novel, and its remarkable advantage is: simple in structure, reasonable in design, low-cost, theftproof performance improves, no potential safety hazard.
