Description

Technical Field

[0001] The utility model relates to the field of pre-buried power sockets for electrical equipment, and more specifically to a pre-buried device for electrical equipment pipelines. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The most important reason why electrical equipment can be used stably is that it needs to use electricity as support. Therefore, before installing electrical equipment, the corresponding circuit pipelines need to be pre-buried to facilitate the subsequent threading and power supply.

[0003] Pre-buried socket devices are required for pre-buried circuit pipelines to facilitate plugging in and taking power after the electrical equipment is installed. In order to improve the safety of the circuit when the electrical equipment is running in the later stage, cables with thicker diameters, larger numbers and harder textures are usually used for pre-buried pipelines. Therefore, when these cables pass through the pre-buried sockets and are coiled and bent inside the pre-buried box, an outward squeezing expansion force will be generated. However, the existing pre-buried box lacks a restraining and limiting structure for the coiled and bent cables, which undoubtedly brings many inconveniences to the installation of the socket panel in the later stage. Therefore, we propose a pre-buried device for electrical equipment pipelines to solve the above-mentioned problems. Utility Model Content
