Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and more specifically, to an insulated power switchgear. Background Technology

[0002] An insulated power switchgear is an electrical device used in power systems for controlling, protecting, monitoring, and isolating circuits.

[0003] In existing technologies, firstly, some device wiring may be piled up haphazardly, resulting in low utilization of cabinet space and increasing the risk of wire damage. Disorganized wiring increases the difficulty of maintenance and repair, as technicians need to spend more time identifying and organizing the wires. Untidy wiring may lead to short circuits or other electrical faults, increasing the risk of safety accidents. Secondly, some devices cannot achieve quick snap-fit ​​and fixation between components, resulting in unstable connections that affect the normal operation of the equipment. Maintenance and replacement of components will be more difficult, requiring more time and tools. Finally, the process of unlocking the snap-fit ​​levers and snap-fit ​​tubes of some devices will be more complex, possibly requiring special tools or skills. The lack of auxiliary mechanisms may lead to low operational efficiency, as each unlocking and re-snapping requires more time and effort. Utility Model Content

The horizontal push rod 11 is horizontally inserted into the snap-fit ​​tube 8. The outer fixing plate 12 is fixedly installed on the outer wall of the snap-fit ​​tube 8. The outer rotating sleeve 13 is rotatably located on the top end face of the outer fixing plate 12. The rotating groove 14 is located on the inner wall of the outer rotating sleeve 13. The rotating groove 14 can press against one end of the horizontal push rod 11 and extend into the snap-fit ​​groove 10 to fix the snap-fit ​​rod 9 in the snap-fit ​​tube 8.

[0030] In this embodiment, the clamping tube 3 is used to fix and organize the wire. The slope block 5 is installed inside the clamping tube 3 to provide inclined support for the push block 6. Rotating the threaded inner tube 4 causes the mating ring 7 to push the push block 6. The push block 6 moves directionally on the slope block 5 and is connected to the threaded inner tube 4 through the mating ring 7. The rubber strip 28 installed on the side of the push block 6 can contact and clamp the wire during the movement of the push block 6 to ensure that the wire will not loosen.

A rubber strip 28 is installed on the side of the push block 6. The push block 6 moves on the slope block 5 so that the rubber strip 28 contacts and clamps the wire.

[0034] More specifically, through the cooperation of push block 6 and slope block 5, the operator can adjust the position and tightness of the wire in clamp tube 3 to keep the line neat. Using the observation and snap-fit ​​mechanism, the snap-fit ​​rod 9 and snap-fit ​​tube 8 are fixed by the rotary groove 14 and the horizontal push rod 11 to ensure a stable connection. The snap-fit ​​auxiliary mechanism is used to unlock the snap-fit ​​rod 9 and snap-fit ​​tube 8 for easy maintenance and replacement.

Rotating the threaded sleeve 15 pushes the push plate 17 upward through the thrust bearing 16, causing the inner push ring 18 to move on the inner wall of the locking tube 8. The top of the inner push ring 18 can push against the receiving block 29, causing the push block 6 to move away from the locking groove 10, thereby unlocking the locking rod 9 and the locking tube 8.

[0038] With the cooperation of push block 6 and slope block 5, the operator can adjust the position and tightness of the wire in clamp tube 3 to keep the line neat. Using the observation snap-fit ​​mechanism, snap-fit ​​rod 9 and snap-fit ​​tube 8 are fixed by rotating groove 14 and horizontal push rod 11 to ensure a stable connection. Snap-fit ​​auxiliary mechanism is used to unlock snap-fit ​​rod 9 and snap-fit ​​tube 8 for easy maintenance and replacement.
