Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of electrical equipment wiring support technical field, more specifically, it relates to a kind of electrical equipment wiring support. BACKGROUND

[0002] In the electrical equipment wiring support technical field, there are many technical problems in the existing products that need to be solved urgently, which seriously affect the safety and aesthetics of wiring, mainly in the following aspects:

[0003] First, the traditional electrical equipment wiring support has obvious functional defects in actual application. Since the length of the connecting wire between the electrical equipment and the main line or socket is usually longer than the actual required distance, the wiring support cannot effectively manage the excess cable. In this case, the excessively long wire will naturally sag, forming irregular arcs. Especially in scenarios where multiple connecting wires need to be supported, the sagging of a large number of cables not only seriously affects the overall aesthetics of the installation environment, but also increases the risk of cable entanglement and chaos. Moreover, once the wire is installed in the wiring shell, the length of the wire cannot be adjusted flexibly, which may require the wiring shell to be disassembled and reassembled for adjustment, resulting in limited operation and time and effort.

[0004] Secondly, the installation and maintenance process of the existing wiring support has significant operational difficulties. The traditional design usually uses two wiring shells spliced to protect and fix the wire. Although this structure has some effect in terms of protection, it exposes serious convenience problems in actual use. Maintenance personnel often need to use specific professional tools when installing or disassembling the wiring shell, which is tedious and time-consuming. This complex disassembly method not only reduces maintenance efficiency, but also increases additional tool costs, causing unnecessary difficulties for daily maintenance work.

[0005] More troublesome is that some improved wiring supports, although they have added quick disassembly and assembly functions in design, attempt to improve installation and maintenance efficiency through simplified structures, but these improved designs still have major defects. These quick disassembly and assembly mechanisms usually use simple buckles or plug-in structures, which face serious stability problems in actual use. Environmental vibrations and temperature changes can cause the connection parts to loosen. These factors, combined with the instability of the connection between the wiring shells, can cause gaps to loosen or even completely fall off, which not only fails to effectively protect the internal cable, but also can cause greater safety hazards.
