Abstract

The invention discloses a semi-closed screw. The semi-closed screw comprises a screw head, a plurality of connecting sections and a screw tail which are sequentially connected, wherein outer threads are formed on the outer circles of the screw head and the multiple connecting sections; a first threaded hole is formed in the tail portion of the screw head; a screw head threaded post is arranged at the front end of each connecting section, and a second threaded hole is formed in the rear end of each connecting section and is the same as the first threaded hole in size; a connecting section threaded post is arranged at the screw tail and is the same as the screw head threaded posts in size. In this way, the semi-closed screw is formed by connecting the multiple connecting sections, the length of the semi-closed screw can be adjusted anytime, the semi-closed screw is universal, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a mechanical part, in particular to a semi-closed screw. Background technique [0002] The existing screw adopts a fully enclosed mechanism, so that the length of the screw is fixed, and the screw needs to be customized when encountering a special machine, which causes unnecessary trouble, not only wastes people's labor, but also wastes resources. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a semi-hermetic screw. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: a semi-closed screw, comprising: a screw head, several connecting sections and a screw tail, wherein the screw head, several connecting sections and the screw tail are sequentially connected; [0005] Both the screw head and the outer rings of several connecting sections are provided with external threads; [0006] The tail of the screw head is ...
