Abstract

A vehicle joint comprises an upper joint, a lower joint, a locking handle, a main shaft, an adjusting screw and a cam, wherein when the upper joint and the lower joint are locked by the locking handle, the upper joint and the lower joint are combined to form three stress points and are in a stable triangular structure.

Description

a vehicle connector

Technical field

The present invention relates to a vehicle joint, in particular to a joint used on the handlebar and frame of bicycles and scooters.

Background technique

At present, quite a lot of joints on the handlebar and frame of the known bicycles and scooters are not stable enough, and they often shake soon after being used, which affects the safety of use.

SUMMARY OF THE INVENTION

In order to overcome the disadvantage that the existing joints on the handlebar and the frame are not stable enough, and often shake soon after use, the present invention provides a stable joint for vehicles.

The technical solution adopted by the present invention to solve the technical problem is as follows: the vehicle joint is composed of an upper joint, a lower joint, a main shaft, a cam, an adjusting screw and a locking handle. are three stress points and form a steady-state triangular structure.

The beneficial effect of the invention is that it can ensure that the three stress points are simultaneously stressed after the upper and lower joints are locked, and the size of the stress can be adjusted by adjusting screws, thereby ensuring the stability of use.

Detailed ways

In Figures 2 and 3, the upper joint (2), the lower joint (1) and the locking handle (5) are assembled together by the main shaft (4) and locked by the main shaft screw (10), the cam (3) The cam limit screw (11) is fixed on the main shaft (4), the lock (7) and the lock return spring (8) are sleeved in the locking handle (5) together, and are limited by the lock The screws (9) are fixed, the handlebar upper tube group (6), the upper joint (2), the return spring (15) and the return guide post (16) are fixed by the return spring limit screw (17) and the set screw ( 18) Set together, the cam limit shrapnel (12) and the cam limit shrapnel locking screw (13) are fixed in the inner cavity of the lower joint (1) together, and the adjusting screw (19) is fixed in the lower joint (1) the upper end of

After assembly, as shown in Figure 1, Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7, when the locking handle (5) is pressed in the (h) direction, the V surface (a) in the upper joint (2) and (b) will come into contact with the V-surfaces (c) and (d) in the lower joint (1), and there will be a guiding effect between the two V-surfaces; when the locking handle (5) is pressed in the direction of (h) Afterwards, the lock (7) will buckle the head of the return spring limit screw (17) in the handlebar upper tube group due to the elastic force of the lock return spring (8) to prevent the locking handle (5) from loosening. At the same time, the cam (3) will withstand the adjusting screw (19), thereby tightening the upper joint (2) and the lower joint (1), at this time, the force-bearing surface (a) in the upper joint and the force in the lower joint are The surface (c) is completely in contact, and the force-bearing surface (b) in the upper joint and the force-bearing surface (d) in the lower joint are completely in contact. When the adjusting screw (19) is adjusted up and down, the contact point (E) will be changed. , (F) and (G), the force points (E), (F) and (G) are in a triangular steady state structure; when the lock (7) is pressed, the lock (7) will compress the lock Buckle the return spring (8), and the lock (7) will disengage from the head of the return spring limit screw (17). ) Continue to pull the locking handle (5) after the resistance of point (M) on the cam limit spring (12), at this time the pressure will be released between the cam (3) and the adjusting screw (19); Under the elastic force of (15), the return guide post (16) will push open the upper joint (2), and then the handlebar upper tube group (6) can move in the direction of (j) to realize the folding function; on the contrary, when When the handlebar upper tube group (6) moves in the direction of (k), the locking handle (5) will not follow the upper joint due to the resistance of the cam (3) at point (N) on the cam limit spring (12). (2) Moving in the direction of (h) together with the handlebar upper tube group (6) will affect the gap between the upper joint (2) and the lower joint (1), so as not to affect the handlebar upper tube group (6) pressing Movement in the direction of (k); the lower joint locking screw (14) is used to lock the lower joint (1) on the upper tube of the front fork of the vehicle. If this joint is used in other parts of a bicycle or scooter, this joint Can be nested or welded.
