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 herein 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, the drawings only show some but not all structures related to the present invention.

[0032] The present embodiment discloses a split pin bolt and a connection assembly, which relate to the field of electric power construction. like 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 penetrated through the nut 3, the end of the bolt body 1 is provided with a V-shaped hole 11, and the outer wall of the bolt body 1 is provided with a clamping groove 12, wherein the V-shaped hole 11 and the clamping groove 12 are mutually Connected. The opening of th...

Abstract

The invention belongs to the field of electric power construction, and discloses a cotter pin bolt and a connection assembly. Cotter pin bolts include a bolt body and a cotter pin. The bolt body is threaded through the nut. A V-shaped hole is opened at the end of the bolt body. A clamping groove is opened on the outer wall of the bolt body. The V-shaped hole and the clamping groove communicate with each other. ; The opening of the cotter pin is a V-shaped structure, and the tail of the cotter pin is provided with a locking protrusion. In the installed state, the split pin is configured to pass through the V-shaped hole, and the snap-in protrusion snaps in to the snap-in groove; in the use state, the split pin is configured to slide relative to the V-shaped hole and extend the bolt Outside the body, the cotter pin can be abutted against the nut. The cotter pin bolt and the connecting assembly provided by the invention have simple structure, convenient installation, improved work efficiency, and prevent problems such as cotter pin omission.

Description

technical field [0001] The invention relates to the field of electric construction, in particular to a split pin bolt and a connecting assembly. Background technique [0002] Cotter pin is a kind of mechanical part. R-type cotter pin is often used in the field of electric power construction. After the nut is tightened, one end of the R-type cotter pin is inserted into the circular hole on the bolt body, and the other end is bent and clamped to clamp the bolt body. The outer wall of the curved clamping portion of the R-type split pin is in contact with the outer wall of the nut, which prevents the nut from loosening. R-type cotter pins are often missed and 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, the drone inspection images often fail to judge the R-type cotter pins. Whether there are omissions, openings and damages has seriously increased the workload ...
