Description

Lock relatively rotate to rack for motor and bicycle

The utility model relates to motorcycle, bicycle trade, is a kind of vehicle safety anti-theft device.

Present bicycle lock both domestic and external still adopts traditional iron plate punch riveting forceps type structure, or steel wire lock.Above-mentioned two classes lock exist to some extent lock body intensity low, be subject to outside destroy and manipulate inconvenient shortcoming.And lock for motorcycle removes " the U-shaped lock bridge is across Front fork lock fixed pattern lock ", does not still have new structure both at home and abroad and occurs.Adopt the padlock locking principle on this lock construction, adopt reciprocal elastic lock tongue insertion lock bridge to give in the opening of cutting and lock.For solve will lock fixing onboard with the purpose of locking vehicle, on the both direction of lock body, respectively processed two lock beam holes, the still fixing needs onboard of lock bridge when adapting to across Front fork lock car and vehicle '.Because this locks similar pad lock structure, by two corresponding dead bolts locking lock bridges, (lock bridge is parallel to the wheel end face when travelling, and is positioned at the front fork tube outside, and parallel with breeches pipe to satisfy the locking of both direction simultaneously again; Locking during vehicle lock bridge be 90 ° in the position of lock bridge when travelling, across the two-tube locking front-wheel of front fork).Can only be by latch bolt position two lock beam holes in vertical each other direction processing, so no matter from which direction locking lock bridge, the locking that must serve as both direction in two dead bolts, owing on both direction, process two holes by a dead bolt, also a dead bolt under any circumstance all can only be exposed, can finish two-way locking.This locking form is used any object and all a dead bolt that exposes could be pushed aside, and of in fact exposing in two dead bolts of this structure exists in name only! In two dead bolts one is inoperative, push the easy degree of the reciprocal dead bolt of another elasticity aside and just well imagine.

In addition, because this lock is independent monomer, be installed in two breeches pipes of steering mechanism outside wherein of vehicle, the side breeches pipe front face area that lock is installed is increased, windage increases.Again since between two breeches pipes mid point of distance for turning to axis of rotation, the installation of (two breeches pipes are apart from mid point distance and frontal resistance unanimity) this lock has increased the front face area (resistance) of a side breeches pipe, increased a side direction turning moment on the as many as vehicle front fork under steam, the lock that the longitudinal stability system of travelling in the former design of vehicle is installed destroys, the installation of monomer lock is a potential very big threat for traffic safety and driver and crew's safety.

In sum the purpose of this utility model be at ask a question, design a kind of survivability strong, easy to operate, and do not influence the vehicle safety lock of front-wheel systems stabilisation substantially.

The design main points:

1. the shear stress that is born when general lockset being subjected to outside destroy changes into and bears compressive stress, tensile stress and flexural stress when being subjected to outside destroy, and makes more component simultaneously stressed.

2. locking the increase support, making lock body, lock bridge rotatable to satisfy the specific (special) requirements of both direction locking.

3. adopt cylinder single pole structure lock bridge, reduce production costs.

4. increase is secondary locks, and corresponding main the lock is installed on the breeches pipe of opposite side, locks the side direction turning moment that produces to eliminate monomer, and the mechanical performance of enforced lock has simultaneously improved the safe antitheft of locking.

Description of drawings:

Fig. 1 the utility model latch-up structure principle sectional drawing

The rotation of Fig. 2 the utility model, location, locking principle sectional drawing

The utility model is achieved in that (referring to accompanying drawing 1, accompanying drawing 2)

Motor, the bicycle lock of support rotation comprise support 1, lock body 3, lock core 5, key 8 and secondary lock relatively; The design is by bearing pin 2 connecting racks 1 and lock body 3; Fork 4 is installed between lock core 5 and the lock bridge 6; Force alignment pin 7 to be installed on the lock body, be processed with 2～3 cams on the lock core 5, force a side pressure of alignment pin 7 on the cam of lock core 5, the other end can embed in the locating hole of support 1; Rotational lock core 5, forces alignment pin 7 to make it mobile at cam on the lock core 5 compressing fork 4, makes it to be embedded in respectively in the locating hole of the arc groove of lock bridge 6 and support 1; Fork 4 between lock core 5 and the lock bridge 6 is 2～3 chip architectures, between its each sheet spring is housed; Lock bridge 6 is the single pole cylinder, has cut 1～5 each cannelure on it; Lock body 3 fixes on locking on the vehicle through support 1; The secondary lock symmetry is assemblied on the car body.

Below its technical essential and each component working relation is launched explanation: (referring to accompanying drawing 1, accompanying drawing 2)

Lock body 3 is connected on the support 1 by bearing pin 2, and lock core 5, fork 4, pressure alignment pin 7, lock bridge 6 are assemblied on the lock body 3. Just can open and close lock bridge and rotation lock body with key 8 rotational lock cores 5, reach the function of lock car.

Be processed with 2～3 cams on the lock core 5, respectively with fork 4, the end in contact of forcing alignment pin 7, rotational lock core 5 makes cam rise to high some compressing fork 4 and forces alignment pin 7 to move it a segment distance, closely embed respectively in the cannelure of lock bridge 6 and in the locating hole of support 1, locking lock bridge and lock body can not move axially lock bridge 6; Lock body can not be rotated. When unblanking key 8 is rotated round about, the cam on the lock core 5 is down to low spot, forces alignment pin to move disengaging support 1 to lock core 5 directions under the effect of spring; Because the cam that contact with fork 4 on the lock core 5 also is down to low spot simultaneously, a slice in the fork 4 is owing to the effect of spring between the fork, moves to lock core 5 and makes two Produce certain interval between the sheet fork, twitch lock bridge 6 this moment and make a slice in the cannelure bank compressing fork on the lock bridge 6 make it to move to another sheet, and the gap between having eliminated two, fork is stepped down to lock bridge, lock bridge 6 just can move axially, and lock body 3 is simultaneously rotatable. Repeat to rotate key 8 and just can lock arbitrarily on request lock body and lock bridge position.

When being used for motorcycle, this lock is set up secondary lock, its structure can be identical with the master lock body, corresponding master lock is installed on another breeches pipe of vehicle front fork, make both sides breeches pipe front face area substantially equal, eliminate front fork owing to the lateral twisting moment that " U " shape monomer lock produces has been installed, strengthened simultaneously the mechanical strength of this lock, improved the anti-theft security performance.
