Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0013] figure 1 It is a structural schematic diagram of a seven-spiral ground clamp according to an embodiment of the present invention, as figure 1 As shown, the structure of the present invention includes a fixed frame 1 and a movable clamp block 2 slidingly connected to the inside of the fixed frame 1. The bottom end of the movable clamp block 2 is in contact with the top end of the screw rod 5. The screw rod 5 is a 7-thread structure, and the bottom end of the screw rod 5 passes through the After passing through the guide hole 7 opened at the bottom of the fixed frame 1, it is fixedly connected with the connecting column 8....

Abstract

The invention discloses a seven-spiral grounding wire clamp, which comprises a fixed frame and a movable clamping block slidably connected with the inner side of the fixed frame, wherein the bottom end of the movable clamping block makes contact with the top end of a screw rod, the screw rod is of a seven-threaded structure, and the bottom end of the screw rod penetrates through a guide hole formed in the bottom end of the fixed frame and then is fixedly connected with a connecting column. According to the seven-spiral grounding wire clamp adopting the structure, the screwing efficiency (the rotating speed of the seven-spiral grounding wire clamp is seven times that of a conventional single thread) is improved by arranging the screw rod with the seven-threaded structure, and the connectingreliability between the screw rod and the positioning cylinder is improved by arranging the positioning spring in the positioning cylinder connected with the screw rod so as to reduce the possibilitythat the screw rod is disengaged from the positioning cylinder.

Description

technical field [0001] The invention relates to a technology of electric power fittings, in particular to a seven-spiral ground clamp. Background technique [0002] When the overhead line is overhauled, it is necessary to connect the grounding wire or grounding rod to the main cable as a temporary short-circuit grounding to ensure the safety of electricity and the safety of operators. The common method is to use the grounding rod to achieve. Existing grounding rods generally include an operating rod and a grounding wire clamp, and the grounding wire clamp includes a fixed frame and a movable clamping block threadedly connected to the fixed frame through a screw rod, wherein the screw rod is mostly a single-threaded structure, and the tightening speed is relatively slow; and the screw rod The multi-positioning cylinder and the positioning screw abut against the bottom end of the movable clamp, and the connection is unreliable. Contents of the invention [0003] The purpose...
