Problems solved by technology

[0002] At present, in the hardware manufacturing industry, there is a kind of captive screw structure, which can ensure that the screw and the riveted part will not be separated during the disassembly process. This kind of screw structure is mainly connected to the screw by the riveted part. The structure of the screw is complicated, and the combination time is relatively long, and it will also damage the structure of the board and affect the function of use; this requires a fast and fast installation without destroying the structure of the board.

Abstract

The invention discloses a stainless steel captive spring combined screw. The screw comprises a bolt body. A spring fixing ring sleeves the bolt body, the outer surface of a spring mounting ring is provided with a protruding second thread, and a spring is arranged between the spring fixing ring and a bolt head. The spring mounting ring sleeves the spring fixing ring, the edge of the spring mountingring is rolled inwards to wrap the spring fixing ring, and the spring fixing ring and the spring mounting ring are rotatably connected. A groove is formed in the surface of an upper circular ring ofthe spring mounting ring, and a protruding block matched with the groove is arranged on the lower surface of the bolt head. The screw is easy and convenient to install, the structure of a plate is protected, the using function of the plate is guaranteed, and it can be guaranteed that the screw cannot be disengaged in the dismounting process with the help of the spring.

Description

technical field [0001] The invention relates to the field of screws, in particular to a stainless steel lock-in spring composite screw. Background technique [0002] At present, in the hardware manufacturing industry, there is a kind of captive screw structure, which can ensure that the screw and the riveted part will not be separated during the disassembly process.
