It is mainly used to distribute high-voltage power (usually 1kV and above) to various branch circuits, provide power to different electrical equipment and loads, and control, protect and monitor the circuits. A high-voltage distribution box that is easy to hang and fix is ​​a type of high-voltage distribution box that is specifically designed for hanging installation, so as to be fixed and installed in specific environments.

[0003] When installing a high-voltage distribution box, the staff will first determine the installation location of the high-voltage distribution box according to the design requirements and the actual site conditions. The installation location should be a dry, well-ventilated place indoors, free from corrosive gases, and easy to operate and maintain, with sufficient space around it. Then, the distribution box is suspended in the predetermined position using appropriate bolts, hangers, etc.

[0004] The existing technology has the following drawbacks: In some existing equipment, the size and shape of the distribution box are fixed. When the staff needs to carry out maintenance indoors, the small internal space of the distribution box makes it inconvenient for the staff to carry out maintenance operations. In addition, the installation and disassembly of the existing distribution box requires multiple bolt tightening operations, which are cumbersome, time-consuming and labor-intensive. Therefore, a high-voltage distribution box that is easy to hang and fix is ​​proposed to solve the above problems. Summary of the Invention

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of a high-voltage distribution box that is easy to suspend and fix, including a back plate 1. A top plate 2 is slidably connected to the inner wall of the back plate 1. The back plate 1 has a slot corresponding to the top plate 2, allowing the top plate 2 to move vertically. Side plates 4 are hinged to the inner wall of the top plate 2 via a movable plate 3. Since the length of the movable plate 3 is fixed, when the top plate 2 moves downward with one end of the movable plate 3, the other end of the movable plate 3 will separate from the two sets of side plates 4. When the top plate 2 moves upward with one end of the movable plate 3, the other end of the movable plate 3 will bring the two sets of side plates 4 together. A box door 6 is hinged to the outer wall of the side plate 4. The box door 6 is closed with the right side plate 4 using existing technology. A base plate 5 is fixedly connected to the outer wall, and a protrusion 12 is fixedly connected to the outer wall of the back plate 1. A wall 7 is inserted into the outer wall of the protrusion 12. A slot corresponding to the protrusion 12 is opened on the wall 7. The protrusion 12 is initially inserted into the slot. A limiting mechanism is provided on the inner wall of the top plate 2, and a disassembly assembly is provided on the inner wall of the back plate 1. The limiting mechanism includes a pull rod 9, which is slidably connected to the inner wall of the top plate 2. A slot corresponding to the pull rod 9 is opened on the top plate 2, allowing the pull rod 9 to move back and forth. The end of the pull rod 9 is elastically connected to the top plate 2 through a movable spring 8. When the pull rod 9 moves backward, the movable spring 8 is compressed. When resetting, the elastic force of the movable spring 8 is used to reset the pull rod 9.

[0035] Reference Figure 1 , Figure 5 and Figure 6 The disassembly assembly includes a locking block 10, which is slidably connected to the inner wall of the back plate 1. The back plate 1 has a slot corresponding to the locking block 10, allowing the locking block 10 to move left and right. The left side wall of the locking block 10 is elastically connected to the back plate 1 via a moving spring 11. When the locking block 10 moves to the left, the moving spring 11 is compressed. When resetting, the elastic force of the moving spring 11 is used to reset the locking block 10. The locking block 10 is engaged with the inner wall of the wall 7. The wall 7 has a slot corresponding to the locking block 10, and the locking block 10 is initially engaged in the slot.

[0036] Reference Figures 2-4 The side plate 4 is slidably connected to the inner wall of the back plate 1. The back plate 1 has a slot corresponding to the side plate 4, allowing the side plate 4 to move left and right. The bottom plate 5 has a rectangular slot. The side plate 4 is slidably connected to the inner wall of the bottom plate 5. A rectangular block is provided at the bottom of the side plate 4. The rectangular block is slidably connected in the rectangular slot. The outer wall of the side plate 4 is in contact with the outer wall of the back plate 1. A rectangular slot is provided on the outer side of the back plate 1. The pull rod 9 is inserted into the inner wall of the back plate 1. The pull rod 9 is initially inserted into the first circular slot. A circular slot is provided on the inner side of the back plate 1. The outer wall of the back plate 1 is in contact with the outer wall of the wall 7. A rectangular slot with the same shape as the protrusion 12 is provided inside the wall 7.

[0037] Working principle: When it is necessary to inspect the internal components of the distribution box, the operator must first open the box door 6, and then manually move the pull rod 9 backward. The pull rod 9 will compress the movable spring 8. When the pull rod 9 separates from the slot on the back plate 1, the operator moves the pull rod 9 downward. The pull rod 9 will move the top plate 2 and the movable plate 3 downward. The other end of the movable plate 3 will separate the two sets of side plates 4, expanding the space inside the distribution box and facilitating the operator's inspection and operation. At this time, the pull rod 9 coincides with the second slot on the back plate 1. The operator can then manually release the pull rod 9 and use the elasticity of the movable spring 8 to insert the pull rod 9 into the box. In the slot of the back panel 1, the side panel 4 is limited. When the maintenance is completed, the operator can move the pull rod 9 backward by hand. When the pull rod 9 is separated from the slot on the back panel 1, the operator can move the pull rod 9 upward by hand. The pull rod 9 will move the top panel 2 and the movable plate 3 upward. The other end of the movable plate 3 will bring the two sets of side panels 4 together. When the side panel 4 moves to the initial position, the operator can manually release the pull rod 9 and let the pull rod 9 insert into the slot of the back panel 1 to limit the side panel 4. Then, the operator can manually close the door 6. If the side panel 4 needs to be adjusted again, the above operation steps can be repeated.

[0038] When the distribution box needs to be disassembled, manually press the locking block 10. The two sets of locking blocks 10 will move closer together and squeeze the moving spring 11. When the locking block 10 separates from the slot on the wall 7, manually remove the distribution box. Then manually release the locking block 10. Use the elastic force of the moving spring 11 to move the two sets of locking blocks 10 to the initial position. When the distribution box needs to be installed, press the locking block 10 with your hand. When the locking block 10 does not block the slot on the wall 7, manually align the protrusion 12 and insert it into the direction of the wall 7. Then manually release the locking block 10 so that the locking block 10 engages in the slot of the wall 7, thus completing the limiting of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
