Abstract
The utility model relates to a fastening device for an explosion-proof switch, and the explosion-proof switch mainly consists of a switch body and a switch heat part. The switch body is in a stereoscopic rectangular structure, and is mainly formed by the combining of a switch door and a switch door frame. The switch body is provided with the fastening device. The fastening device mainly consists of a locking ring and a locking handle. The locking ring is in a U-shaped structure, and a side of the locking ring is provided with a threaded hole which cooperates with the locking handle for work. The locking handle is formed by the combination of a threaded rod and a handle. The threaded rod on the locking handle passes through the locking ring through the threaded hole at a side of the locking ring, and enables the switch body to be completely fastened. Through employing the fastening device provided by the utility model, the explosion-proof switch body cannot enable water to be leaked into the switch, thereby greatly improving the safety factor. The fastening device is convenient to use, is simple in structure, and is convenient to operate.
Description
Technical field
