Abstract
The utility model relates to an expansion brake bicycle lock. The lock is contained in a casing of a bicycle brake, and the lock and the bicycle brake are combined into a whole, wherein a brake pendulum rod of the bicycle brake is provided with a ratchet wheel part; the top end of a lock bolt of the lock is provided with a spring sheet, the top end of which is provided with a support tooth which is matched with a ratchet wheel. The lock is characterized in that when a heavy bob is used for knocking the part of a lock core, the bicycle brake is seriously deformed because the material of the bicycle brake is thin so that a brake shoe is tightly attached to a brake drum. Thus a bicycle can not be started, and the lock just can be destroyed but not unlocked. The utility model can overcome the defect that the existing bicycle lock can be fast unlocked by knocking by the heavy bob, and has the advantages of good theft-proof performance and simple and reliable structure.
Description
Technical field
The utility model relates to a kind of lockset, especially forms the lock lock that rises of one with brake.
Background technology
At present, the known lockset that is used for motor bike, mini-motorcycle, bicycle is and independently is arranged at outside the car body, only needs can open fast with weight blow lockset, and very easily stolen, theftproof performance is poor.
Summary of the invention
In order to overcome the deficiency that existing lock only need can be opened fast with weight blow lockset.The utility model provides a kind of lock lock that rises, and this lock is formed one with brake, knocks the lock core position with weight, can cause gross distortion because of the brake material is thin, makes brake rubber block be close to brake drum, and car just can't start, and can only destroy and can't open, and theftproof performance is good.
The technical scheme that its technical matters that solves the utility model adopts is: lock is loaded in the brake forms one with brake, and housing and vehicle frame join together, and brake drum and wheel join together.Action was divided into for two steps during locking, at first lock core was in closed condition, and this moment, dead bolt and top spring leaf thereof ejected, and the support tooth on this spring leaf top is close to the ratchet portions of the fork that brakes.Second step was tightened up brake, and drive the brake fork by brake steel wire and reverse along little axle, the ratchet portions that makes support tooth one sound of baby talk tighten up the brake fork, the fork that brakes simultaneously drives brake rubber block and tightens up, and makes it be close to brake drum, makes car be in braking state.Therefore, ratchet changes with the engage position of support tooth, has compensated the wearing and tearing of brake rubber block simultaneously.Releasing of brake then, the ratchet portions of fork locks because the support tooth will brake, still maintains the lock status.Need only during unlatching lock core is in opening, support tooth and spring leaf are with the dead bolt indentation, the ratchet portions of brake fork is unclamped, the brake fork is returned to can free rotary state, clockwise under the effect of brake fork spring force, the brake fork drives brake rubber block to be loosened, and makes and produces one section space between brake rubber block and the brake drum, the brake drum connection can freely be rotated with wheel, make car be in normal operating condition.
The beneficial effects of the utility model are: this lock and brake are formed one, knock the lock core position with weight, can cause gross distortion because of the brake material is thin, make brake rubber block be close to brake drum, car just can't start, and can only destroy and can't open, theftproof performance is good, and simple and reliable for structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure cross-sectional schematic when being in locking states.
Fig. 2 is the structure cross-sectional schematic when to be that this reality is novel be in unlocking condition.
Among the figure: 1. 2. 3. ratchet portions 5. brake rubber blocks 6. brake steel wires 7. little axles of dead bolt 3a. spring leaf 3b. support tooth 4. brake fork 4a. brake forks of brake drum (joining together) of housing (joining together) with wheel with vehicle frame
Brake fork spring, brake drum and wheel coupling part, the housing profile and with the vehicle frame coupling part, parts such as lock core structure do not belong to this patent, omit picture among the figure.
The specific embodiment
In Fig. 1, housing (1) joins together with vehicle frame, and brake drum (2) joins together with wheel.Action was divided into for two steps during locking: at first lock core is in closed condition.This moment, dead bolt (3) and top spring leaf (3a) thereof ejected, and the support tooth (3b) on this spring leaf top is close to the ratchet portions (4a) of the fork that brakes.Second step was tightened up brake, driving brake fork (4) by brake steel wire (6) changes along little axle (7) conter clockwise, the ratchet portions (4a) that makes support tooth (3b) sound of baby talk tighten up the brake fork, the fork (4) that brakes simultaneously drives brake rubber block (5) and tightens up, make it be close to brake drum (2), make car be in braking state.Therefore, ratchet changes with the engage position of support tooth, has compensated the wearing and tearing of brake rubber block simultaneously.Releasing of brake then, the ratchet portions (4a) of fork locks because support tooth (3b) will brake, still maintains the lock status.
In Fig. 2, need only during unlatching lock core is in opening, support tooth (3b) and spring leaf (3a) are with dead bolt (3) (referring to Fig. 1) indentation, the ratchet portions (4a) of brake fork is unclamped, brake fork (4) is returned to can free rotary state, at brake fork spring (because of not belonging to this patent, omitting among the figure and draw) cw changes under the elastic force effect, brake fork (4) drives brake rubber block (5) to be loosened, make and produce one section space between brake rubber block (5) and the brake drum (2), making brake drum (2) join same wheel (because of not belonging to this patent, do not omit among the figure and draw) can freely rotate, and makes car be in normal operating condition.
Claims (1)
- A kind of lock lock that rises, partly be made up of brake and lock core etc., it is characterized in that: this lock is included in the brake housing forms one with brake, and the brake fork of brake is provided with ratchet, the dead bolt top of lock is provided with spring leaf, and this spring leaf top is provided with the support tooth makes it match with above-mentioned ratchet.
