Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a detachable distribution box that is easy to transport. Background Technology

[0002] As a core device in the power system used to distribute electrical energy and protect circuit equipment, distribution boxes are widely used in various fields such as building engineering, industrial production, municipal construction and outdoor power operation and maintenance. With the rapid development of the power industry, the demand for distribution boxes in various engineering projects continues to grow, and the application scenarios are becoming increasingly diversified, including commercial buildings and residential communities in cities, as well as infrastructure projects and outdoor temporary power supply sites in remote areas. This places higher demands on the transportation convenience of distribution boxes.

[0003] The prior art (Chinese patent announcement number: CN222146945U, publication date: 2024-12-10) discloses a detachable distribution box, including a back panel and a front panel. A bottom plate is fixedly connected to the bottom of the back panel, and a top plate is fixedly connected to the top of the back panel. Symmetrical hinges are fixedly connected to both sides of the front panel, and side plates are fixedly connected to the other end of the hinges. A fixing plate is fixedly connected to the side of the side plate away from the front panel. A screw passes through the fixing plate and is threadedly connected to the back panel. In this detachable distribution box, the side plates hinged to both sides of the front panel are slidably connected to the bottom plate and the top plate. When the staff needs to inspect the inside of the distribution box, the front panel and the side plates can be removed from the back panel together, which makes it easier to inspect the inside of the distribution box and makes it more convenient to repair the electrical components on both sides of the inside of the distribution box. The prior art (Chinese patent publication number: CN115566557A, publication date: 2023-01-03) discloses a power distribution box that is easy to disassemble and maintain. The base is a cuboid structure with a mounting groove at the center of its top surface. A fan is horizontally positioned within the mounting groove. A bottom plate covers the top surface of the base and has ventilation openings at the corresponding mounting groove positions. Four uprights are vertically positioned at the four corners of the base. A front, left, right, and rear side plate are connected to the front, left, right, and rear sides of the bottom plate via hinges. A top plate is fixed to the top of the four uprights. The bottom plate, front, left, right, rear, and top plates form a closed space. One end of a bolt is located on the side wall of the upright, and the bolt and nut are used to fix the front, left, right, and rear side plates to their respective uprights. The advantage is convenient maintenance. Although existing distribution boxes can be disassembled, it requires tightening multiple bolts to separate them, which is cumbersome. Furthermore, it is impossible to centrally position the disassembled components, making them prone to scattering during subsequent transportation, thus presenting certain defects in use. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable distribution box that is easy to transport, comprising a base plate, side plates, and a top plate that are assembled together. The base plate is supported by a mounting bracket fixed to the installation position. The top plate has a fixing plate fixed to the installation position on its outer side, and a cover plate is elastically rotatably mounted on the upper end of the fixing plate. A first positioning component for snapping and positioning is provided between the upper end of the side plate and the top plate. A sealing bladder for improving the joint sealing is embedded in the outer side of the side plate. A second positioning component is provided between the lower end of the side plate and the base plate. The second positioning component is adjusted via the sealing bladder. An adjustment component for controlling the first positioning component is provided on the top plate. An adsorption component is provided on the upper surface of the top plate, and when the base plate and top plate adsorb, they clamp and position the disassembled and stacked side plates.

[0006] Preferably, the first positioning component includes a first positioning block fixedly installed on the top of the side panel and a first positioning groove formed on the lower surface of the top panel, with the first positioning block and the first positioning groove being in clearance fit. The second positioning component includes a second positioning block fixedly installed on the lower end of the side panel and a second positioning groove formed on the upper surface of the bottom panel, with the second positioning block and the second positioning groove being in clearance fit.

[0007] Preferably, the control component includes a rotary seat that is elastically rotatably mounted on the lower surface of the top plate, and a first locking block is slidably mounted on the inner side of the first positioning groove. A first spring is fixedly connected between the inner wall of the first positioning groove and the first locking block. At the same time, a pull cable is fixedly connected between the rotary seat and the first locking block. During the rotation of the rotary seat, the pull cable is wound around to control the first locking block to slide along the first positioning groove.

[0008] Preferably, the positions of the first positioning block and the first locking block are set in correspondence, and the first locking block is inserted between the side plate and the first positioning block during the sliding process to achieve positioning of the upper part of the side plate.

[0009] Preferably, the sealing bladder is arranged in a ring structure, and the upper end of the sealing bladder is squeezed during the movement of the first locking block towards the first positioning block, and the sealing bladders on the adjacent side plates are sealed and fitted together.

[0010] Preferably, the second positioning component further includes a second locking block telescopically mounted on the second positioning block, and one end of the second locking block near the sealing bladder is fixedly bonded to the outside of the sealing bladder. The inner wall of the second positioning groove is provided with a slot laterally, and the sealing bladder pushes the second locking block to slide into the slot after being compressed and deformed.

[0011] Preferably, the adsorption assembly includes an adsorption seat fixedly mounted on the top plate and a rotating shaft fixedly mounted on the rotary seat, with the rotating shaft being elastically rotatably mounted on the top plate, and a piston plate being lifted and lowered on the inner side of the adsorption seat.

[0012] Preferably, guide posts are symmetrically fixedly installed on the upper surface of the top plate, and a piston plate slides through the outer side of the guide posts. At the same time, a rotating shaft slides through the center of the piston plate. A ball bearing is embedded in the inner wall of the through hole in the center of the piston plate, and a spiral guide groove is opened on the outer side of the rotating shaft. During the rotation of the rotating shaft, the ball bearing slides along the guide groove to drive the piston plate to adjust its height. Both the rotating shaft and the guide posts are sealed to the piston plate.

[0013] Preferably, an adsorption plate is installed at the center of the upper surface of the base plate, and a second spring is fixedly connected between the adsorption plate and the base plate. During the disassembly and transportation of the base plate and side plates, the adsorption plate adheres to the outside of the adsorption seat. At the same time, the adsorbed base plate and side plates clamp and fix the four stacked side plates by the elastic force of the second spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the easily transportable detachable distribution box can be easily disassembled and assembled, facilitating transportation and subsequent maintenance, as detailed below; 1. The device is equipped with a first positioning block, a second positioning block, a first locking block, a rotary seat, and a second locking block. By inserting the second positioning block at the lower end of the side plate into the second positioning groove on the bottom plate, the side plate and the bottom plate are initially spliced ​​together. Then, the rotary seat on the top plate is rotated, causing the rotary seat to pull the first locking block to slide via a cable. The first positioning block at the upper end of the side plate is then inserted into the first positioning groove on the lower surface of the top plate. After releasing the rotary seat, the first locking block locks the first positioning block. At the same time, the sealing bladder is squeezed, causing the sealing bladder to push the second locking block to slide and lock the second positioning block, thereby assembling the various panels of the distribution box. Subsequently, the box can be easily disassembled by rotating the rotary seat. Furthermore, a sealing bladder is provided. As the top of the sealing bladder is compressed, the sealing bladder can deform and bulge, thereby achieving effective sealing between the various plates.

[0015] 2. It is equipped with a mounting bracket, fixing plate, cover plate and suction base. The mounting bracket can support the base plate, which makes it easy to wall-mount the distribution box. The suction base can attach to the cover plate to fix the horizontal position of the distribution box. At the same time, the cover plate can cover and protect the box. 3. The device is equipped with an adsorption seat and an adsorption plate. The disassembled side plates are stacked on the outside of the base plate, and then the top plate is stacked on the outside of the stacked side plates. At the same time, the knob seat is rotated, and then the adsorption plate is pulled and attached to the outside of the adsorption seat. Then the knob seat is released, so that the piston plate moves inside the adsorption seat, thereby adsorbing and fixing the adsorption plate. At this time, the base plate and the side plates can clamp and position the stacked side plates under the action of the second spring, which facilitates subsequent centralized transportation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Existing distribution boxes are inconvenient to disassemble and assemble, making them difficult to transport and maintain. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-10 As shown; a detachable distribution box for easy transportation includes a base plate 1, side plates 2 and a top plate 3 that are assembled together. The base plate 1 is supported by a mounting bracket 4 fixed to the installation position. The top plate 3 has a fixing plate 5 fixed to the installation position on its outer side. The upper end of the fixing plate 5 is elastically rotatably fitted with a cover plate 6. A first positioning component for snap-fit ​​positioning is provided between the upper end of the side plate 2 and the top plate 3. A sealing bladder 15 for improving the splicing sealing is embedded in the outer side of the side plate 2. A second positioning component is provided between the lower end of the side plate 2 and the base plate 1. The second positioning component is adjusted by the sealing bladder 15. An adjustment component for controlling the first positioning component is provided on the top plate 3. An adsorption component is provided on the upper surface of the top plate 3.

[0020] The first positioning component includes a first positioning block 7 fixedly installed on the top of the side plate 2 and a first positioning groove 10 formed on the lower surface of the top plate 3, with the first positioning block 7 and the first positioning groove 10 in clearance fit. The second positioning component includes a second positioning block 8 fixedly installed on the lower end of the side plate 2 and a second positioning groove 9 formed on the upper surface of the bottom plate 1, with the second positioning block 8 and the second positioning groove 9 in clearance fit. The adjustment component includes a knob seat 13 elastically rotatably installed on the lower surface of the top plate 3, and a first locking block 11 is slidably installed on the inner side of the first positioning groove 10, and the inner wall of the first positioning groove 10 and the first... A first spring 12 is fixedly connected between the locking blocks 11, and a pull cable 14 is fixedly connected between the rotary seat 13 and the first locking block 11. During rotation, the rotary seat 13 winds around the pull cable 14 to control the first locking block 11 to slide along the first positioning groove 10. The positions of the first positioning block 7 and the first locking block 11 are correspondingly set, and the first locking block 11 is inserted between the side plate 2 and the first positioning block 7 during sliding, achieving positioning of the upper end of the side plate 2. The sealing bladder 15 has a ring-shaped structure, and during the movement of the first locking block 11 towards the first positioning block 7, it presses against the upper end of the sealing bladder 15, and... The sealing bladder 15 on the adjacent side plate 2 is sealed and fitted. The second positioning assembly also includes a second locking block 16 telescopically mounted on the second positioning block 8, and the end of the second locking block 16 near the sealing bladder 15 is fixedly bonded to the outside of the sealing bladder 15. The inner wall of the second positioning groove 9 is provided with a slot 901. After the sealing bladder 15 is deformed by pressure, it pushes the second locking block 16 to slide into the slot 901. The adsorption assembly includes an adsorption seat 17 fixedly mounted on the top plate 3 and a rotating shaft 1301 fixedly mounted on the toggle seat 13. The rotating shaft 1301 is elastically rotatably mounted on the top plate 3. A piston plate 19 is installed on the inner side of the adsorption seat 17. A guide post 18 is symmetrically fixed on the upper surface of the top plate 3, and the piston plate 19 slides through the outer side of the guide post 18. At the same time, the rotating shaft 1301 slides through the center of the piston plate 19. A ball bearing 20 is embedded in the inner wall of the through hole in the center of the piston plate 19. A spiral guide groove 1302 is opened on the outer side of the rotating shaft 1301. During the rotation of the rotating shaft 1301, the ball bearing 20 slides along the guide groove 1302 to drive the piston plate 19 to adjust its height. Both the rotating shaft 1301 and the guide post 18 are sealed to the piston plate 19.

[0021] The mounting bracket 4 and fixing plate 5 are fixed in the pre-installed position with bolts. Then, the base plate 1 is placed on top of the mounting bracket 4. Next, the second positioning block 8 at the lower end of the side plate 2 is inserted into the second positioning groove 9 on the base plate 1 to achieve the initial splicing of the side plate 2 and the base plate 1. Then, the rotary seat 13 on the top plate 3 is rotated, so that the rotary seat 13 pulls the first locking block 11 to slide through the cable 14 and squeezes the first spring 12. Then, the first positioning block 7 at the upper end of the side plate 2 is inserted into the first positioning groove 10 on the lower surface of the top plate 3. At the same time, the cover plate 6 is rotated so that the cover plate 6 fits against the top of the adsorption seat 17. Then, the rotary seat 13 is released, so that the first locking block 11 locks the first positioning block 7. At the same time, the sealing bladder 15 is squeezed, so that the sealing bladder 15 pushes the second locking block 16 to slide and lock the first positioning block 7. The two positioning blocks 8 are locked to enable the assembly of the various panels of the distribution box. When the knob seat 13 is released, the rotating shaft 1301 will rotate and reset elastically, causing the ball bearing 20 to roll along the spiral guide groove 1302, thereby driving the piston plate 19 to move down along the guide post 18, so that the adsorption seat 17 can adsorb the cover plate 6. At the same time, as the top of the sealing bladder 15 is compressed, the sealing bladder 15 can deform and bulge, thereby achieving effective sealing between the various panels. The mounting bracket 4 can support the base plate 1, making it easy to wall-mount the distribution box. The adsorption seat 17 can adsorb the cover plate 6 to fix the horizontal position of the distribution box. At the same time, the cover plate 6 can cover and protect the box. The box can be easily disassembled by rotating the knob seat 13.

[0022] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. While existing distribution boxes can be disassembled, they cannot centrally restrain the disassembled components, making them prone to scattering during transportation. To further solve this technical problem, this example discloses the following technical content: Figures 1-2 and Figures 11-12 As shown; when the base plate 1 and top plate 3 are adsorbed, the disassembled and stacked side plates 2 are clamped and positioned. An adsorption plate 21 is installed at the center of the upper surface of the base plate 1, and a second spring 22 is fixedly connected between the adsorption plate 21 and the base plate 1. During the disassembly and transportation of the base plate 1 and the side plates 2, the adsorption plate 21 adheres to the outside of the adsorption seat 17. At the same time, the adsorbed base plate 1 and the side plates 2 clamp and fix the four stacked side plates 2 by the elastic force of the second spring 22.

[0023] The disassembled side plates 2 are stacked on the outside of the base plate 1, and then the top plate 3 is stacked on the outside of the stacked side plates 2. At the same time, the knob seat 13 is rotated, and then the adsorption plate 21 is pulled and attached to the outside of the adsorption seat 17. Then the knob seat 13 is released, so that the piston plate 19 moves inside the adsorption seat 17, thereby adsorbing and fixing the adsorption plate 21. At this time, the base plate 1 and the side plates 2 can clamp and position the stacked side plates 2 under the elastic force of the second spring 22, which facilitates subsequent centralized transportation.
