The invention belongs to the technical field of springs, and particularly relates to a special-shaped spring. The special-shaped spring comprises a special-shaped spring main body, wherein a threadedcolumn is arranged at one end of the special-shaped spring main body, the threaded column and the special-shaped spring main body are of an integrated structure, one end of the threaded column is provided with a protective sleeve, the outer surface of the connecting screw rod is provided with a screw disc, the end part of the connecting screw rod is provided with a connecting pressing rod, and theconnecting position of the connecting pressing rod and the connecting screw rod is provided with an annular column. Through designing inner fastening pads on the surface of the protective sleeve anda spring piece at the connecting position of the inner fastening pads and the protective sleeve, the situation that that the protective sleeve is not convenient to replace after the protective sleeveis damaged in use and is not convenient to fasten after being replaced is avoided, the protective sleeve can be clamped on the outer surface of the connecting pressure rod after replacement, the protective sleeve is tightly fixed to the outer surface of the connecting pressing rod through the action of elastic deformation of the spring piece, and the problems that the protective sleeve is inconvenient to replace after being damaged and is inconvenient to fasten after being replaced are solved.
Description
technical field [0001] The invention belongs to the technical field of springs, and in particular relates to a special-shaped spring. Background technique [0002] The difference between the existing special-shaped springs and conventional springs is that the spring itself is irregular, with bending and a large number of complex angle designs, and the manufacturing and processing technology is also relatively demanding, and the equipment is also relatively demanding. Generally, it is wound by a computer. , for some special occasions, the material of the variable diameter spring is generally a circular cross-section material, and most of them bear the compressive load; the existing special-shaped springs are inconvenient to replace when the connecting pressure rod breaks during use, and it is inconvenient to adjust the connecting pressure when replacing and using. The length of the rod makes it inconvenient to replace and fasten after the protective sleeve is damaged during u...
