Description

Technical Field

[0001] This utility model belongs to the field of sleeve technology, specifically relating to a substation electrical installation sleeve. Background Technology

[0002] In the installation and maintenance of electrical equipment in substations, socket tools are essential assembly tools used to tighten or loosen bolts, nuts, and other fasteners. Traditional socket tools typically employ a fixed structure, where the socket and handle are connected by welding or integral molding. This necessitates carrying multiple socket tools when changing to different socket sizes, increasing tool weight and reducing work efficiency. Furthermore, while some quick-release socket tools allow for rapid socket changes, their connection structures often suffer from the following problems:

[0003] Insufficient connection stability: Some quick-release mechanisms use spring pins or snap-fit ​​designs, which are prone to loosening or even falling off during high-torque operations, causing the sleeve to slip and affecting construction safety. Cumbersome operation: Some quick-release mechanisms require two-handed operation, such as pressing buttons on both sides simultaneously to disassemble the sleeve, which is extremely inconvenient in confined spaces or at heights. Poor durability: Frequent disassembly and assembly will cause wear on components such as springs and snap-fits in the quick-release mechanism, shortening the tool's lifespan. Limited compatibility: Some quick-release mechanisms are only compatible with specific sleeve sizes, failing to meet the operational needs of various bolt sizes in substations.

[0004] While some improved quick-release socket tools are available on the market, such as those using magnetic adsorption or threaded connections, they still have the following drawbacks:

[0005] Magnetic adsorption type: The magnetic force is easily affected by oil and iron filings, and the sleeve may fall off due to insufficient magnetic force during high-torque operations. Threaded connection type: Although the connection is stable, the installation and removal speed is slow, and the threads are prone to wear or corrosion, affecting long-term use.

[0006] Furthermore, in substation electrical installation work, due to the complex working environment (such as working at heights, in confined spaces, and with live wires), the ease of use and safety of tools are particularly important. Traditional socket tools cannot meet the requirements for quick replacement, stable connection, and one-handed operation, resulting in low construction efficiency and even the potential for safety accidents due to tool failure.
