[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] An insulating through-wall bushing structure, such as Figures 1-7 As shown, the device includes an insulating sleeve body 1 and a sleeve head 2. An installation plate 3 is fixedly installed on the outer wall of the insulating sleeve body 1 near one end of the sleeve head 2. One end of the sleeve head 2 is located inside the installation plate 3. An annular groove 18 is formed on the outer wall of the installation plate 3. Several installation plates 4 are slidably connected inside the annular groove 18. One end of the installation plate 4 is T-shaped, which can match the shape inside the annular groove 18, so that one end of the installation plate 4 can slide without disengaging from the annular groove 18. Adjustment plates 7 are slidably connected inside the several installation plates 4. An installation hole 16 is formed through the outer wall of the adjustment plate 7 near one end. Movable grooves 15 are formed on the upper and lower surfaces of the adjustment plate 7 near one end. A locking block 11 is movably installed inside each of the two movable grooves 15.
[0028] The mounting plate 4 has several slots 19 on both inner sidewalls, and the slots 19 fit into the blocks 11. A spring plate 12 is provided between the inner wall of the movable groove 15 and the outer wall of the blocks 11. The adjusting plate 7 can be moved along the inside of the mounting plate 4. The adjusting mounting holes 16 correspond to different fixed positions. When the adjusting plate 7 is moved, the blocks 11 move with the adjusting plate 7 and gradually move out of the slots 19. The spring plate 12 is squeezed and contracted until the position of the adjusting plate 7 is moved. Under the action of the spring plate 12, the blocks 11 can be driven into the corresponding slots 19 to fix the position between the adjusting plate 7 and the mounting plate 4. Each block 11 is provided with a chamfer that matches the slot 19 to ensure that it can move smoothly under the elastic action of the spring plate 12.
[0029] The mounting plate 4 has sliding grooves 13 on both outer side walls. A movable frame 21 is slidably connected to the outside of the mounting plate 4 through the sliding grooves 13. A tension spring 14 is installed between the inner wall of the sliding groove 13 and the outer wall of the movable frame 21. A retaining plate 8 is rotatably connected to one end of the movable frame 21 through a shaft. Several limiting blocks 20 are fixedly connected to the outer wall of the mounting plate 3, and the limiting blocks 20 fit with the retaining plate 8. By setting multiple limiting blocks 20, the mounting plate 4, which slides along the inside of the annular groove 18, can be fixed at multiple points, expanding the adjustability of the position of the mounting plate 4. This allows it to adapt to different shaped panel walls, improves the applicability of fixing the mounting plate 3, and further improves the convenience of installing the insulating through-wall sleeve structure and the applicability of the insulating through-wall sleeve structure. After adjusting the position of the mounting plate 4, simply slide the movable frame 21 along the inside of the mounting plate 4 and rotate the retaining plate 8 so that the retaining plate 8 is engaged in the limiting block 20 to fix the position between the mounting plate 4 and the mounting plate 3. The operation is relatively convenient.
[0030] When this insulating through-wall bushing structure is used inside an electrical cabinet, it is fixed to the mounting panel in the cabinet using mounting plate 3. During installation, simply pass the insulating through-wall bushing structure through the mounting plate 3, ensuring the outer wall of the mounting plate 3 is flush against the panel. Then, rotate the mounting plate 4 along the annular groove 18 to the desired fixing position. Fix its position using the movable frame 21, the locking plate 8, and the limiting block 20. Next, pull the adjusting plate 7 inside the mounting plate 4 to adjust the position of the mounting hole 16 to correspond to the desired fixing position. The locking block 11 and spring plate 12, together with the locking groove 19, fix the position between the adjusting plate 7 and the mounting plate 4, so that it can flexibly adapt to various shapes of panels. It is used to fix the mounting plate 3. After adjustment, the external fixing parts, such as screws, are fixed to the panel wall through the mounting hole 16, thus fixing the mounting plate 3 and fixing the insulating through-wall sleeve structure. The installation is completed. At this time, the cable can be passed through the insulating sleeve body 1 and the sleeve head 2 to connect the various components in the electrical cabinet, so that the insulating through-wall sleeve structure can cover and insulate the cable.
[0031] The inner wall of the mounting plate 3 has an annular groove 17. Several sliders 9 are fixedly connected to the outer wall of the tube sleeve 2, and the sliders 9 fit into the annular groove 17. Several grooves 5 are formed on the outer wall of the mounting plate 3, and the grooves 5 fit into the sliders 9. The outer wall of the sliders 9 has a screw groove 10. Several fixing screws 6 are inserted into the outer wall of the mounting plate 3, and the fixing screws 6 cooperate with the screw groove 10. The sliders 9 are located inside the annular groove 17. By passing the fixing screws 6 through the mounting plate 3 and rotating them into the screw groove 10, the position of the sliders 9 can be fixed, thereby fixing one end of the tube sleeve 2 to the mounting plate 3. Similarly, the tube sleeve 2 can be easily removed from the mounting plate 3, so that the tube sleeve 2 can be easily separated from the insulating tube sleeve body 1, avoiding the whole body from being scrapped due to damage to one of them, thus achieving the purpose of saving resources.
[0032] Specifically, when wear occurs inside the sleeve head 2 or the insulating sleeve body 1, affecting the insulation effect, simply unscrew each fixing screw 6 from the mounting plate 3 to release the fixing of the slider 9, then rotate the sleeve head 2 so that each slider 9 corresponds to the position of each groove 5, and the sleeve head 2 can be removed from the mounting plate 3, separating the sleeve head 2 or the insulating sleeve body 1, allowing maintenance and replacement of one of the components without replacing the entire insulating through-wall sleeve structure, effectively saving resources and operating costs.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
