However, the barrier material is not easy to position after covering the cable, and the cable is not easy to adjust its position later.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference structure for an electrical control system, comprising an electrical control cabinet and a cable, wherein the electrical control cabinet is provided with an anti-interference shielding box, and the anti-interference shielding box has a U-shaped structure, and a side flip cover is hinged and fixed to the side opening end of the anti-interference shielding box; an inherent positioning seat is locked inside the anti-interference shielding box, and a limiting groove is provided on the positioning seat; the cable is covered with an anti-interference coating layer, and the cable is locked in the limiting groove.

[0007] Preferably, an adjusting limit rod is fixed inside the electrical control cabinet by plugging in, and an installation beam is also fixed inside the electrical control cabinet by snapping in.

[0008] Preferably, the mounting beam has first through holes spaced evenly at intervals, and the mounting beam and the second through holes are positioned corresponding to each other.

[0009] Preferably, the anti-interference shielding box has symmetrically integrated limiting protrusions at the upper and lower ends of its back, and the limiting protrusions are movably connected to the adjusting limiting rod.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: an anti-interference structure for an electrical control system, including an electrical control cabinet 1 and cables 7. The electrical control cabinet 1 is equipped with an anti-interference shielding box 3, which is made of metal with anti-interference function. A vertically arranged partition 6 is welded and fixed to the inside of the electrical control cabinet 1, and a second wire-passing hole 601 is horizontally opened on the partition 6. This structure allows for the separation of the front electrical components from the rear cables 7 through the partition 6. The second wire-passing hole 601 is used for threading the cables 7. The anti-interference shielding box 3 has a U-shaped structure. Furthermore, a side-opening cover 4 is hinged to the side opening of the anti-interference shielding box 3. The side-opening cover 4 is hinged for easy opening and closing. An adjusting limit rod 8 is fixed to the inside of the electrical control cabinet 1 via a plug-in connection. An installation beam 2 is also snap-fitted into the inside of the electrical control cabinet 1. This installation beam 2 is used for electrical installation positioning and allows for wire threading. The installation beam 2 has evenly spaced first wire-passing holes 201, and the installation beam 2 corresponds to the second wire-passing holes 601. This structure allows the cable 7 to pass through the corresponding second wire-passing holes. Between hole 601 and mounting beam 2, the inner side of anti-interference shielding box 3 is locked with the fixed positioning seat 301, and the positioning seat 301 has a limit groove 302. The upper and lower ends of the back of anti-interference shielding box 3 are symmetrically provided with integrated limit protrusions 303, and the limit protrusions 303 are movably connected with the adjusting limit rod 8. This structure allows anti-interference shielding box 3 to move through the cooperation of limit protrusions 303 and adjusting limit rod 8, thereby realizing the adjustment of the cable 7 spacing. The cable 7 is covered with an anti-interference covering layer 5, and the cross section of the anti-interference covering layer 5 is C. The structure allows the anti-interference covering layer 5 to be secured to the outside of the cable 7, achieving the protection of the cable 7. The anti-interference shielding box 3 allows the cables 7 to be fixed separately in various locations, achieving a highly efficient anti-interference effect. The cable 7 is secured in the limiting groove 302. The inner side of the side flip cover 4 is glued and fixed with a fastening plate 401, and the fastening plate 401 contacts and cooperates with the positioning seat 301. This structure allows the side flip cover 4 and the anti-interference shielding box 3 to form a square tube structure that runs vertically through the cable after they are closed, so that the anti-interference covering layer 5 is installed on the outside of the cable 7 and a positioning structure is provided, achieving double-layer anti-interference protection.

[0018] Working principle: When using the anti-interference structure of this electrical control system, firstly, when the cable 7 in the electrical control cabinet 1 is fixed, the anti-interference covering layer 5 covers the outside of the cable 7, and then the cable 7 is clamped in the limiting groove 302 of the positioning seat 301. After the side flip cover 4 is closed, the fastening plate 401 clamps the cable 7, so that the cable 7 forms a double-layer anti-interference structure through the anti-interference covering layer 5 and the anti-interference shielding box 3. The cable 7 then passes through the second wire hole 601 opened on the partition plate 6 into the electrical control cabinet 1, and is threaded through the first wire hole 201 opened on the mounting beam 2. The anti-interference shielding box 3 moves on the adjusting limit rod 8 through the limiting protrusion 303, and the spacing of the cable 7 is adjusted as needed, thereby completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
