Description

Technical Field

[0001] The present invention relates to the technical field of bicycle production, and particularly to an adjustable placement rack for bicycle handlebars during production. Background Art

[0002] A bicycle, also known as a pedal bike or cycle, is usually a small two-wheeled vehicle for land use. A bicycle mainly consists of components such as a frame, handlebars, front fork, drive system, braking system, wheels, etc. Among them, the handlebars and the front fork form the steering system of the bicycle, and the rider controls the direction of the bicycle by holding the handlebars.

[0003] The bicycle handlebars are of a symmetrical structure. When producing bicycle handlebars, operations such as grinding and painting need to be carried out on the outer wall. When these processes are carried out, a placement rack is required to fix the handlebars. The existing form of the placement rack for fixing the handlebars is to insert the handlebars into the fixing holes symmetrically arranged on two groups of fixing plates, use the fixing holes to fix the handlebars, and make the handlebars suspended between the two groups of fixing plates. This form of placement rack has the problem of inconvenient use. When fixing the two ends of the handlebars with the fixing holes on the fixing plates, it is necessary to manually hold the handlebars to keep them completely horizontal to achieve quickly inserting the handlebars into the fixing holes at one time. The operation difficulty is high, and generally, a placement rack of one size can only fix handlebars of one model size, with poor adjustability. Therefore, the present invention proposes an adjustable placement rack for bicycle handlebars during production to solve the deficiencies in the prior art. Summary of the Invention

[0004] Aiming at the above problems, the purpose of the present invention is to provide an adjustable placement rack for bicycle handlebars during production. The form of fixing the handlebars is to directly place them into the placement grooves, which has the advantage of simple operation. The limiting mechanism can stably fix the two ends of the handlebars in the placement grooves. The displacement driving mechanism controls the transmission mechanism connected to the first rotating shaft and the second rotating shaft to act, which can control the first rotating seat and the second rotating seat to rotate, so that placement grooves of different sizes can be rotated to the highest position for fixing the handlebars, thereby meeting the requirement of fixing the two ends of handlebars with different diameters, and the adjustability of the placement rack is high.

Then, the limiting mechanism 5 is controlled to move so that the limiting mechanism 5 abuts and fixes the two ends of the bicycle handle. When it is necessary to fix bicycle handles of different sizes, the transmission mechanism is controlled to act by using the displacement driving mechanism 2, so that the first rotating shaft 12 and the second rotating shaft 13 rotate, and the placement grooves 14 with appropriate sizes on the first rotating seat 3 and the second rotating seat 4 are rotated to the highest positions at the tops of the first rotating seat 3 and the second rotating seat 4.
