[0026] See also Figure 1-3 A relay contact protection structure includes a protection box 1 and a protection adjustment component. The top middle of the protection box 1 is opened and the inner wall of the opening is provided with dust-proof grass 2. The protection box 1 is provided with a protection adjustment component near the top.

[0027] The protective adjustment assembly includes two adjusting rods 3, two movable seats 4 and two clamping seats 5. Both ends of the two adjusting rods 3 are rotatably connected to the inner wall of the protective box 1 through bearings. The outsides of the two adjusting rods 3 are provided with threaded sections and are rotatably connected to the two movable seats 4. The two movable seats 4 are fixed with bolts on one side close to each other and the other clamping seats 5 respectively.

[0028] In this embodiment, the protection box 1 is in an inverted U shape and connecting feet are provided on both sides of the bottom. The side of the protection box 1 is rotatably connected to the side door 10 through a shaft.

[0029] It should be noted that the inverted U-shaped design of the protective box 1 allows it to easily cover the relay contacts, while the connecting feet at the bottom provide stable support and installation points, ensuring that the protective box 1 can be firmly fixed to the outside of the relay contacts and is not easily affected by external vibrations or collisions.

[0030] In this embodiment, the two adjusting rods 3 are completely consistent in shape, size and thread shape. The thread segments outside the two adjusting rods 3 are each provided with two sections with opposite thread directions. The two moving seats 4 are respectively threadedly connected to the thread segments on both sides of the two adjusting rods 3.

[0031] It should be noted that the shape and thread design of the adjusting rod 3 ensure that they can rotate synchronously, and because the threads are in opposite directions, when the adjusting rod 3 rotates, the two movable seats 4 can move in opposite directions respectively under the guidance of the threads, thereby realizing flexible adjustment of the cable clamping width.

[0032] In this embodiment, the clamping seat 5 is composed of a fixed block and a clamping block. The fixed block is fixed to one side of the movable seat 4 by bolts. One side of the clamping block is arc-shaped and has arranged and distributed rubber blocks inside.

[0033] It should be noted that the design of the clamping seat 5 allows it to be fixed on the moving seat 4 and move with the movement of the moving seat 4. The arc-shaped design of the clamping block can adapt to cables of different diameters, and the rubber block provides a soft and stable clamping force, avoiding excessive pressure or scratches on the cable, while increasing the friction between the cable and the clamping seat, improving the stability of the clamping.

[0034] In this embodiment, two steel rails 6 are inserted into the interior of the moving seat 4 . The two steel rails 6 are symmetrically distributed and located on the outside of the adjusting rod 3 . Both ends of the steel rails 6 are fixed to the inner wall of the protection box 1 by bolts.

[0035] It should be noted that the introduction of the rail 6 provides a stable guide and support for the movement of the moving seat 4, ensuring the stability and accuracy of the moving seat 4 during the adjustment process. At the same time, the fixed connection between the rail 6 and the inner wall of the protection box 1 also enhances the stability and reliability of the entire protection structure.

[0036] In this embodiment, the protective adjustment assembly further includes two first gears 7 and one second gear 8 , one end of the two adjustment rods 3 is extended and the two first gears 7 are respectively fixed to the external bolts of the extended ends of the two adjustment rods 3 .

[0037] It should be noted that the introduction of the first gear 7 and the second gear 8 realizes the synchronous rotation of the adjusting rod 3. By rotating the knob block 9, the rotation speed and direction of the adjusting rod 3 can be conveniently controlled, thereby realizing precise adjustment of the cable clamping width.

[0038] In this embodiment, the second gear 8 is located between the two first gears 7 and its two sides are meshed with the two first gears 7. A small shaft is fixed with bolts in the middle of the second gear 8. The small shaft is rotatably connected to the protective box through a bearing. One end of the small shaft passes through the side wall of the protective box and is fixed with a knob block 9 with bolts.

[0039] It should be noted that the knob block 9 is used as an interface for user operation, and by rotating it, the rotation of the second gear 8 can be conveniently controlled, thereby realizing the control of the entire protection adjustment assembly. This design makes the user operation more intuitive and convenient, and also improves the usability and user experience of the entire protection structure.

[0040] Working principle:

[0041] First, bolt the protection box 1 to the outside of the contact to be protected, then pass the cable to be connected through the top of the protection box 1, open the side door to fix the cable end to the contact point, straighten the cable close to the clamping seat, and turn the knob block 9, which in turn drives the second gear 8, the two first gears 7 and the two adjusting rods 3 to rotate. Since the two adjusting rods 3 are provided with threaded sections with opposite thread directions on the outside and are threadedly connected to the two movable seats 4, the two movable seats 4 can approach each other, thereby driving the clamping seat 5 to clamp the cable to protect the cable.

[0042] Beneficial effects:

[0043] The relay contact protection structure is easy to install and fix through the inverted U-shaped design of the protection box 1 and the connecting feet at the bottom, while the top opening and the dust-proof grass 2 effectively prevent the intrusion of dust. By turning the knob block 9, the second gear 8 and the two first gears 7 can be driven to engage, thereby driving the synchronous rotation of the two adjusting rods 3. Since the outside of the adjusting rod 3 is provided with threaded sections with opposite thread directions, the two moving seats 4 can move toward each other under the guidance of the rail 6, and then the cables are stably clamped by the clamping block and rubber block of the clamping seat 5, thereby realizing the protection of the docking point cables. This structure not only has a good dustproof effect, but also has flexible adjustment and stable clamping. It effectively solves the problems of relay contact disconnection and poor contact caused by the external environment and cable pulling, and ensures the stability and safety of the electrical control system.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
