Structure of desk leg

Abstract

The invention discloses a structure of a student desk / chair leg. The inner cavity of rectangular section steel is provided with a clapboard at a position close to the opening position of the inner cavity. The shape of the clapboard is similar with the shape of the inner cavity section of the rectangular section steel. The clapboard is fixedly connected with the rectangular section steel through welding. A polyurethane rubber pad is arranged at the opening of the rectangular section steel, and a tapping screw is inserted in a matching way to fix the polyurethane rubber pad at the outside of the clapboard. The end part of the polyurethane rubber pad is protruded out of the opening of the rectangular section steel for a certain height. In the structure disclosed by the invention, the phenomena that the student desk / chair has noise and a short service life, and does not have a shock absorption function due to the damage of a rubber sleeve caused by burrs existing at the end part in the process of the section of the section steel and the small contact area of the section of the section steel, which is in contact with the bottom surface of the rubber sleeve, can be avoided; and simultaneously, the problems of the rubber sleeve, such as complicated structure, higher cost and difficulty in maintenance are solved. The use is convenient, and an environment-friendly effect is achieved.

Description

Technical field [0001] The invention relates to a furniture for daily use, in particular to a desk leg structure. Background technique [0002] At present, some student desk and chair manufacturing units are increasingly using section steel as the main components of the desk and chair legs. At the same time, in order to achieve the purpose of shock absorption, noise prevention, wear resistance, and easy balance of the desks and chairs, some student desks Chair manufacturing units mainly use rubber sleeves with the same shape as the outer section of the section steel to cover the ends of the legs. However, due to the truncation process of the section steel, there will inevitably be some burrs on the ends, and the straight edges and corners have similar cutting edges. Due to the small contact area between the section of the steel section and the bottom surface of the rubber sleeve, the rubber sleeve is particularly vulnerable to damage, so that the desks and chairs are shock-ab...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effects of the present invention are: the invention can effectively avoid the burr at the end of the section steel and the small contact area between the cross section of the section steel and the bottom surface of the rubber cover during the cutting process of the section steel, which will easily cause the rubber cover to be damaged, thus making the desks and chairs unsuitable. Shock absorption, noise, short life; at the same time, it also solves the problems of complex structure, high cost and troublesome maintenance of the rubber sleeve
