Abstract

A vehicle joint consists of an upper joint, a lower joint, a locking handle, a main shaft, an adjusting screw and a cam. When the locking handle locks the upper joint and the lower joint, the combination forms three stress points and presents a stable triangular structure.

Description

Vehicle joint

Technical Field

The invention relates to a vehicle joint, in particular to a joint used on a handlebar and a frame of a bicycle and a scooter.

Background

At present, the joints on the handlebars and the frame of the known bicycles and scooters are quite unstable, and shake occurs after frequent use, which affects the use safety.

Disclosure of Invention

In order to overcome the defect that the existing joints on the handle bars and the frame are not stable enough and shake occurs soon after being used frequently, the invention provides a stable joint for a vehicle.

The invention solves the technical problems by adopting the technical scheme that the vehicle connector consists of an upper connector, a lower connector, a main shaft, a cam, an adjusting screw and a locking handle, wherein after the upper connector and the lower connector are locked by the cam, the connector is provided with three stress points after being combined and is in a stable triangular structure.

The invention has the advantages that the three stress points can be ensured to be stressed simultaneously after the upper joint and the lower joint are locked, and the stress is adjusted by the adjusting screw, so that the use stability is ensured.

The locking device comprises a stress surface of an upper joint (2), a stress surface of the upper joint (2), a stress surface of a lower joint (1), a stress surface of the lower joint (1), a locking direction of a locking handle (5), i an opening direction of the locking handle (5), j an opening and folding direction of a handlebar upper tube group (6), k a closing combination direction of the handlebar upper tube group (6), E a stress point of a main shaft (4), F a stress point when the stress surface (a) of the upper joint (2) is combined with the stress surface (c) of the lower joint (1), G a stress point when the stress surface (b) of the upper joint (2) is combined with the stress surface (d) of the lower joint (1), and a contact point of a cam (3) and a cam limit elastic piece (12) when the locking handle is opened, N a contact point of the cam (3) and the cam limit elastic piece (12) when the locking handle is fully opened.

Detailed Description

In fig. 2 and 3, an upper joint (2), a lower joint (1) and a locking handle (5) are combined together by a main shaft (4) and locked by a main shaft screw (10), a cam (3) is fixed on the main shaft (4) by a cam limit screw (11), a lock catch (7) and a lock catch return spring (8) are sleeved in the locking handle (5) together and fixed by a lock catch limit screw (9), a handlebar upper tube group (6), the upper joint (2), a return spring (15) and a return guide post (16) are sleeved together by a return spring limit screw (17) and a set screw (18), a cam limit spring piece (12) and a cam limit spring piece screw (13) are fixed in an inner cavity of the lower joint (1) together, an adjusting screw (19) is fixed at the upper end of the lower joint (1),

After assembly, as shown in fig. 1,3, 4,5, 6 and 7, when the locking handle (5) is pressed in the direction (h), the V-faces (a) and (b) in the upper joint (2) are contacted with the V-faces (c) and (d) in the lower joint (1), a guiding effect is generated between the V-faces, when the locking handle (5) is pressed in the direction (h), the lock catch (7) can be buckled on the head of the return spring limit screw (17) in the handlebar upper tube group under the elastic force of the lock catch return spring (8), the locking handle (5) is prevented from loosening, meanwhile, the cam (3) can bear against the adjusting screw (19), so that the upper joint (2) and the lower joint (1) are tensioned, at the moment, the stress face (a) in the upper joint is completely contacted with the stress face (c) in the lower joint, the stress face (b) in the upper joint is completely contacted with the stress face (d) in the lower joint, when the locking handle (19) is pressed up and down, the lock catch (E) is changed, the contact point (F) and the lock catch (G) are stressed by the return spring (7) and the head (7) are compressed, and the lock catch (F) is separated from the head (7) under the condition that the force of the lock catch (7) is compressed by the pressure, the locking handle (5) can be pulled out in the direction of (i), the locking handle (5) is pulled out after overcoming the resistance of the cam (3) at the point (M) on the cam limiting elastic sheet (12), the pressure is released between the cam (3) and the adjusting screw (19), the return guide post (16) can push the upper joint (2) under the elastic force of the return spring (15), then the upper handlebar tube group (6) can move in the direction of (j) to realize the folding function, conversely, when the upper handlebar tube group (6) moves in the direction of (k), the locking handle (5) can not influence the gap between the upper joint (2) and the lower joint (1) due to the resistance of the cam (3) at the point (N) on the cam limiting elastic sheet (12) and move in the direction of (h) together with the upper handlebar tube group (6), so that the lower joint locking screw (14) is used for locking the lower joint (1) on the front fork upper handlebar tube of a vehicle, and if the upper handlebar tube group (6) moves in the direction of (k), the lower joint locking screw (14) can be welded at the joint or other joints of a bicycle.
