Embodiment 1

[0077] Such as Figure 1-5 with Figure 10 as shown,

[0078] This handrail manufacturing process comprises the steps:

[0079] A, material preparation: manufacture the armrest cover 10 of integral injection molding; manufacture inner support rod and armrest plate; the production process of this inner support rod comprises the following steps:

[0080] S1. Process the L-shaped elbow b1, take a metal pipe, fix the metal pipe horizontally, and then use a forming mold to process a U-shaped connection part b11 on one end of the metal pipe and punch several connection positioning holes on the U-shaped connection part b11 b111, mill out the positioning groove b12 at the other end of the metal pipe, and then bend the middle part of the metal pipe by 90°, that is, make an L-shaped elbow;

[0081] Process the strip connecting plate b3, take the metal plate, process at least one strip plate with a stamping die, then use the punching die to process nail holes b31 at both ends of the s...

Embodiment 2

[0115] The structure and working principle of this embodiment are basically the same as those of the first embodiment, except that the cylindrical column a14 is molded by injection molding and the metal connecting sleeve a2 is embedded.

Abstract

The invention belongs to the technical field of chair accessories and especially relates to a manufacturing technology for a handrail. The manufacturing technology for the handrail can be used for solving the technical problems of low assembling efficiency, and the like, of the prior art. The manufacturing technology for the handrail comprises the following steps: A) preparing raw materials: preparing an integrally injection-molded handrail sleeve, and manufacturing an inner support rod and a handrail plate; B) assembling: sleeving the lower end of the handrail sleeve from the upper end of anL-shaped elbow, blocking the middle part of a bar-shaped connecting plate in a locating slot, and then inserting a fastener into a stepped hole on the middle part of the bar-shaped connecting plate, stretching the fastener into a nut and connecting with the nut through a thread, distributing the bar-shaped connecting plate and a U-shaped connecting part in a crossing form, penetrating two bolts through the upper end of the handrail sleeve, penetrating the bolts through bolt holes on the two ends of the bar-shaped connecting plate and connecting with the handrail plate, thereby obtaining the handrail. The manufacturing technology for the handrail has the advantage that the assembling efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of chair accessories, in particular to an armrest manufacturing process. Background technique [0002] A chair is a sitting device. [0003] The structure of the chair includes the chair supporting feet, the backrest and the seat board, as well as the armrests and so on. [0004] In the field of armrests of swivel chairs, it generally adopts a plastic sleeve, a metal inner support, and a structural assembly of the armrest to form the armrest. The handrail is generally made of metal pipes, which are inserted into the plastic sleeve and then connected with the handrail board to fix the handrail board. [0005] When the handrail is connected with the handrail board, the connection plate is used for connection. [0006] The existing assembly process is: before inserting the L-shaped handrail into the plastic sleeve, the connecting plate is welded to the end of the L-shaped handrail inserted into the plastic s...
