Abstract
Disclosed is a fixing lock for bicycles. The body of a lock head is cast into molding by hard metal; a lock sleeve is bent by seamless steel; the end part of a lock sleeve is inserted into the lock head and is riveted in the lock head; the end of a lock shaft is directly inserted into the lock head for locking. Each component has compact structure and firmness without easy breaking weak links, and the utility model has stronger destroy resistance ability and good theft proof and safety functions.
Description
The utility model relates to a kind of stationary bicycle lock.
The major defect of existing fixed formula bicycle lock is a little less than the survivability.Its reason mainly is that structural defective causes: the lock tube of (1) lock is combined by the iron plate of two drawings, as long as with screwdriver or other sharp-pointed instruments lock tube is pried open, pushes the fixedly locking plate of lock shaft gently aside, and lock can be opened.(2) fixedly the locking plate of lock shaft is connected outside the tapered end, and structure is thin, and a little less than the anti-impact force, easy deformation when being subjected to external force collision causes the automatic breakdown of lock.When (3) lock was closed, the spring of traction lock shaft was in extended state, the easy fatigue fracture of spring.
The purpose of this utility model is in order to overcome the shortcoming on the existing stationary bicycle lock construction, to design a kind of structure closely, firmly, the stationary bicycle lock that survivability is strong.
The utility model is achieved in that the cast form of this body and function of tapered end hard metal, and lock tube forms with the seamless steel pipe bending.End at tapered end has a blind hole that is connected with lock tube, after an end of lock tube is inserted, is cemented in the tapered end with rivet.The other end of tapered end has a lock shaft hole, and this hole communicates with the locking plate that is loaded on tapered end inside.One end end face of lock shaft is hemispherical, has groove near end position, and the other end of lock shaft has a through hole that connects handgrip.When the pulling handgrip, when the lock shaft end being inserted in the lock shaft hole of tapered end, the locking plate in the tapered end just is stuck in the groove of lock shaft, and lock is promptly locked.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing in detail structure of the present utility model is described in detail.Lock is made up of tapered end (1), lock tube (3), lock shaft (6), spring (5), handgrip (4), lock tube lid (7).Parts such as lock gall, lock pearl, spring, locking plate are loaded onto in the cast form of this body and function of tapered end hard metal inside.One end of tapered end (1) has a blind hole that is connected with lock tube (3), and the back is inserted with rivet (2) riveted joint in the lock tube end, polishes exposing the outer manufactured head of tapered end then.Can prevent to connect rivet is like this prized.The other end of tapered end (1) has the jack of a lock shaft (6), communicates with the locking plate that is loaded on tapered end inside.Lock tube (3) forms with the seamless steel pipe bending, opens the long arc shape sealing one at the end mill near tapered end, as the guide groove of handgrip (4).Burn-on two in the inboard of lock tube and to lock ear, as the bearing that is fixed on the bicycle.Lock shaft (6) adopts the cold-drawn round steel bending to form, and its external diameter is than the little 4-5 millimeter of internal diameter of lock tube (3).One end end face of lock shaft (6) is hemispherical, is having a groove near end place, as the fixing origin of force of lock shaft of locking plate, is drilled with a radial direction through hole at the other end of lock shaft (6), is used to insert handgrip (4).Handgrip (4) is a three-sectional reducing small cylinder.The root of handgrip (4) inserts in the through hole of lock shaft from lock tube, is connected with the hole tight fit, and protrudes lock shaft 0.5-1 millimeter.Spring (5) is inserted in the gap between lock tube (3) and the lock shaft (6) for the compression spring, and an end holds out against the root of handgrip (4), and the other end holds out against the lock tube lid.When lock was locked, the spring in the lock tube was in compressive state.When with key locking plate being pushed aside in the lock shaft groove, lock shaft is compressed spring immediately and flicks, and lock promptly is opened.Because spring is not subjected to tension in the whole switching process of lock, thereby overcome the shortcoming that the spring of old-fashioned lock is broken easily.Lock tube lid (7) is the pipe of one section one end sealing, and round tube inside diameter is identical with the external diameter of lock tube.Open a hole that diameter is bigger slightly than lock shaft diameter at the center of blind end, lock shaft penetrates wherein.After lock tube end and lock tube lid press-fit, can cover at lock tube and bore an aperture, fixed with lock tube spot welding in the hole, make its connection more firm, at last the weld bond equating.
The utility model has overcome the weakness that existing stationary bicycle lock easily is damaged, and all parts close structure, firmly is not easy to the weak link of breaking up, and has stronger survivability, and the burglary insurance performance is good.
Claims (3)
1, a kind of stationary bicycle lock is made up of tapered end, lock shaft, lock tube, spring, handgrip, lock tube lid, it is characterized in that:
The cast form of this body and function of A tapered end hard metal has a blind hole that is connected with lock tube (3) at an end of tapered end (1), at the other end patchhole of a lock shaft (6) is arranged, and this hole communicates with the locking plate that is loaded on tapered end inside;
B lock tube (3) forms with the seamless steel pipe bending, and an end of lock tube inserts behind the connecting hole of tapered end with rivet (2) riveted joint, and the other end is packed into fixed in the lock tube lid (7);
