Friction-resistant structure of lifting table leg and mounting method of friction-resistant structure

Abstract

The invention relates to the technical field of lifting tables, in particular to a friction-resistant structure of a lifting table leg and a mounting method of the friction-resistant structure. The friction-resistant structure comprises a lower wear-resistant piece mounted at the lower end of an inner pipe of the lifting table leg and an upper wear-resistant piece mounted at the upper end of an outer pipe of the lifting table leg, first protruding parts are symmetrically arranged on the side wall of the lower wear-resistant piece, first connecting holes are formed in the positions, corresponding to the protruding parts of the lower wear-resistant piece, of the lower end of the inner pipe, the first protruding parts of the lower wear-resistant piece are connected with the first connecting holes corresponding to the lower end of the inner pipe in a buckled mode, second connecting holes are formed in the three side walls of the upper end of the outer pipe, an outer edge bent outwards is arranged at the upper end of the upper wear-resistant piece, second protruding parts are arranged on the three side walls of the upper wear-resisting piece and connected with the second connecting holes in the upper end of the outer pipe in a buckled mode, and the outer eave is buckled to the top of the outer pipe. Friction between the inner pipe and the outer pipe is effectively prevented, the protruding parts of the wear-resistant pieces are connected with the connecting holes in the inner pipe wall and the outer pipe wall in a buckled mode to play a fixing role, the wear-resistant pieces are prevented from falling off, and meanwhile installation is easy, convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of lift tables, in particular to a friction-resistant structure of lift table legs and an installation method thereof. Background technique [0002] In many industrial and civil fields, the technology of inner and outer pipe sockets is used for lifting and lowering, and this situation has also been widely used in lifting table legs. The lifting technology of the inner and outer tube sockets requires a wear-resistant sheet in the middle to isolate the inner and outer tubes, so as to prevent direct contact between the inner and outer tubes and prevent friction. At the same time, it also plays a stabilizing role during the rising process of the inner tube. However, the current technology on the market has the following common shortcomings: 1. After a long period of lifting and lowering, the wear-resistant sheet can no longer prevent the friction between the inner and outer tubes, and generate noise at the same...

Problems solved by technology

However, the current technology on the market has the following common shortcomings: 1. After a long period of lifting and lowering, the wear-resistant sheet can no longer prevent the friction between the inner and outer tubes, and generate noise at the same time; , the wear-resistant sheet in the middle does not play the role of stabilizing the inner tube, and the inner tube is easy to shake during the rising process, and finally the top table board cannot bear the load well or the load is limited; 3. After a period of use, friction will occur The piece is brought out by the rising inner tube, and even then falls off to the outside; 4. Due to the narrow space between the inner and outer tubes, it is inconvenient to install
