Detailed Description

As shown in fig. 1 to 7, a limiting shaft for a physiotherapy chair comprises a cylindrical main body stable matching column 1 with a central shaft in an up-down direction, wherein the central positions of the upper end and the lower end of the main body stable matching column 1 are respectively provided with a cylindrical first connecting support column 2 and a second connecting support column 3 which are integrally formed, and the first connecting support column and the second connecting support column form an integral structure of the connecting shaft. The outer cylindrical surface upper end of the first connection support column 2 and the outer cylindrical surface lower end position of the second connection support column 3 are respectively provided with a main body fastening connection thread groove 4 with the same specification, the installation and the matching are carried out through the structure when the whole fastening connection is carried out, the operation during the assembly is ensured to be more convenient, the number of accessories in the connection in the vertical direction can be reduced, and the production connection cost is reduced. The main part is equipped with integrated into one piece and is bilateral symmetry's main part installation cooperation spacing post 5 respectively in the outer cylinder left and right sides of the stable cooperation post 1 of main part, can cooperate together with the protective sleeve subassembly, and stability when the guarantee cooperation is connected is better, has the condition emergence that prevents rotatory off tracking.
