AI Technical Summary

Technical Problem

When installing and disassembling bolts, the existing high-voltage isolation knife switch needs to be removed first, and the disassembled side needs to be supported, which is more troublesome.

Method used

A high-voltage isolation knife switch installation structure is designed. By setting multiple sets of No. 1 screw holes on the outside of the fixed frame, fixing plates and No. 2 bolts are installed inside. The balls are fixed at the end of the No. 2 bolts, and the fixed plates are placed in the fixed frame. , plug the second bolt into the first screw hole, so that the ball is stuck in the ball clamp, and multiple groups of second screw holes are installed on the outside of the fixing plate, and the inner wall of the second screw hole is fixed with a fixing ring, and the outer side of the second bolt Set up a nut, and one side of the fixing ring is fixed with a deformable ball hood. Multiple groups of springs are installed on the outside of the ball hood. Turn the nut to fix the number two bolt. When the fixing plate is subjected to force through the spring, The ball sleeve is displaced inside the ball sleeve to prevent the nut from loosening, and rotate the nut in reverse to pull out the second bolt, thereby directly removing the fixing plate. Multiple sets of knife switches are installed on the top of the fixing plate to prevent the number one bolt from sliding out through the self-locking structure of the worm and the worm gear.

Benefits of technology

By cooperating with the rotating nut and spring, the nut connected to the fixing plate is prevented from loosening, which simplifies the disassembly process of the fixing plate, and prevents the number one bolt from slipping out through the self-locking structure of the worm and the worm gear, improving the convenience of installation and disassembly.

Abstract

The utility model discloses a mounting structure of a high-voltage isolation switch, which relates to the field of mounting structures of high-voltage isolation switches, and comprises a fixing frame, a plurality of groups of first screw holes are arranged on the outer side of the fixing frame, a fixing plate is arranged in the fixing frame, second bolts are arranged in the first screw holes, and the second bolts are arranged in the second screw holes. A ball is fixed to the tail end of the second bolt, multiple sets of second screw holes are formed in the outer side of the fixing plate, a fixing ring is fixed to the inner wall of each second screw hole, a nut is arranged on the outer side of each second bolt, a deformable spherical clamping sleeve is fixed to one side of each fixing ring, and multiple sets of springs are arranged on the outer side of each spherical clamping sleeve. According to the fixing plate, the rotating nut and the spherical clamping sleeve are arranged to conduct certain displacement in the spherical sleeve, the nut connected in the fixing plate is prevented from loosening, the nut is reversely rotated, the second bolts on the two sides are pulled out, and therefore the fixing plate is directly detached.
