Problems solved by technology

[0002] Before designing the rollator, I saw with my own eyes that the hidden place of the electric wheelchair support frame driven by an old man was dangerously broken due to corrosion. This is the inevitable oxidation corrosion of ordinary steel pipes. I also learned that after heat treatment of aluminum alloy, only the surface Hard layer, poor wear resistance after damage

Abstract

The invention provides a welding-free rollator. The welding-free rollator is characterized in that a frame is a triangular frame formed by combining a stainless steel straight pipe with a stainless steel frame upper fixing assembly (1), a frame front wheel fixing assembly (3) and a frame rear wheel fixing assembly (4); frame middle fixing assemblies (2) on two sides are fixedly connected with theframe front wheel fixing assembly (3) through stainless steel transverse pipes; and a saddle is fixed to a transverse connecting pipe installed on the frame middle fixing assemblies (2). The saddle isfixed to a saddle fixing part (A) of a front rod fixing piece (102) of the frame upper fixing assembly (1) when a person walks, so that the maximum walking space is guaranteed; the old person standsin the center of the rollator and the body is supported with the help of elbow supporting assemblies (6) installed on frames on two sides to guarantee the traveling safety; and after being rotated andput down, the saddle is supported by a saddle supporting set (5) in the middle of each frame, and a user has a rest through the saddle. The whole rollator has no welding part, so that processing personnel are prevented from being injured by the welding-polluted environment.

Description

technical field [0001] The invention relates to the technical field of a rollator, in particular to a welding-free rollator. Background technique [0002] Before designing the rollator, I saw with my own eyes that the hidden place of the electric wheelchair support frame driven by an old man was dangerously broken due to corrosion. This is the inevitable oxidation corrosion of ordinary steel pipes. I also learned that after heat treatment of aluminum alloy, only the surface The hardness layer has poor wear resistance after damage. In line with safety first, stainless steel is selected in production, its corrosion resistance is safer, but argon arc welding is required in stainless steel processing, which is a welding technology that uses argon as a protective gas. Argon arc welding has a great harm to the human body. The most important thing is that it has burns on the respiratory tract, lungs, eyes and other parts of the human body. It may cause electro-optic ophthalmia or ...
