Problems solved by technology

R-type cotter pins are often missed or replaced by foreign objects during installation. Due to the thicker bolts often blocking the R-type cotter pins and the problem of the shooting angle of the drone, it is often impossible to judge the R-type cotter pins in the inspection images of the drone. Whether there are omissions, openings and damages will seriously increase the acceptance workload and slow down the acceptance work and project commissioning process

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] This embodiment discloses a cotter pin bolt and a connection assembly, which relate to the field of electric power construction. Such as figure 1 and figure 2 As shown, the cotter pin bolt includes a bolt body 1 and a cotter pin 2 . The bolt body 1 is pierced through the nut 3, a V-shaped hole 11 is opened at the end of the bolt body 1, and a clamping groove 12 is opened on the outer wall of the bolt body 1, wherein the V-shaped hole 11 and the clamping groove 12 are mutually connected. The opening of ...

Abstract

The invention belongs to the field of power construction, and discloses a cotter pin bolt and a connecting assembly. The cotter pin bolt comprises a bolt body and a cotter pin, wherein the bolt body penetrates through a nut; a V-shaped hole is formed in the end of the bolt body; a clamping groove is formed in the outer wall of the bolt body; the V-shaped hole and the clamping groove are communicated with each other; a cotter pin opening is of a V-shaped structure; and a clamping bulge is arranged at the tail of the cotter pin. In the installation state, the cotter pin is configured to be arranged in the V-shaped hole in a penetrating manner, and the clamping bulge is clamped in the clamping groove. In the use state, the cotter pin is configured to slide relative to the V-shaped hole and extend out of the bolt body, so that the cotter pin can abut against the nut. The cotter pin bolt and the connecting assembly provided by the invention are simple in structure and convenient to install,so that the working efficiency is improved, and the problems of cotter pin omission and the like are prevented.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to a cotter pin bolt and a connecting assembly. Background technique [0002] Cotter pin is a kind of mechanical part. R-shaped cotter pin is often used in the field of electric power construction. After the nut is tightened, insert one end of the R-shaped cotter pin into the circular hole on the bolt body, and the other end bends the clamping part to clamp the bolt body, so that The outer wall of the curved clamping part of the R-shaped cotter pin abuts against the outer wall of the nut to prevent the nut from loosening. R-type cotter pins are often missed or replaced by foreign objects during installation. Due to the thicker bolts often blocking the R-type cotter pins and the problem of the shooting angle of the drone, it is often impossible to judge the R-type cotter pins in the inspection images of the drone. Omissions, openings, and damages have seriously increased t...
