Problems solved by technology

[0004] The traditional slotted nut has several protrusions evenly distributed in the ring on the nut body, and a groove is formed between any two adjacent protrusions. The groove is used in conjunction with the pin. However, in actual use, to ensure the tightness of the nut and ensure that the groove corresponds to the pin hole on the screw rod, it is necessary to tighten and disassemble the nut several times, and add washers to ensure the tightness of the nut And the groove corresponds to the pin hole on the screw, so it is inconvenient to use and the tightening efficiency is low

Abstract

The invention discloses an anti-loosening subway rail nut. The anti-loosening subway rail nut comprises a first nut body, a plurality of inserting bodies, a connecting body, a T-shaped sleeve body, asecond nut body, an annular body, a connecting protrusion, a plurality of inserting grooves and a plurality of fixing nails, wherein the inserting bodies are arranged at the rear end of the first nutbody, the front end of the small-diameter section of the T-shaped sleeve body is provided with an inserting groove matched with the inserting body in a one-to-one correspondence mode, the small-diameter section of the T-shaped sleeve body is sequentially sleeved with the second nut body and the connecting body from front to back, and the small-diameter section of the T-shaped sleeve body is provided with external threads matched with the second nut body. Compared with the prior art, the anti-loosening subway rail nut has the advantages that the use is convenient, the tightening efficiency is improved, and the anti-loose effect is good.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of fasteners, in particular to the technical field of anti-loosening subway track nuts. [0003] 【Background technique】 [0004] The traditional slotted nut has several protrusions evenly distributed in the ring on the nut body, and a groove is formed between any two adjacent protrusions. The groove is used in conjunction with the pin. However, in actual use, to ensure the tightness of the nut and ensure that the groove corresponds to the pin hole on the screw rod, it is necessary to tighten and disassemble the nut several times, and add washers to ensure the tightness of the nut And the groove corresponds to the pin hole on the screw rod, so it is inconvenient to use and the tightening efficiency is low. [0005] 【Content of invention】 [0006] The purpose of the present invention is to solve the problems in the prior art, and to propose an anti-loosening subway track nut, which is easy to use and...
