Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a wall-mounted distribution box that is easy to assemble and disassemble. Background Technology

[0002] Wall-mounted distribution boxes are electrical devices that are suspended on walls using fixed brackets or mounting brackets. They are widely used in residential, commercial buildings, industrial facilities, and other places. As a core component of the power system, the main function of the distribution box is to centrally manage and distribute electrical energy, and to centrally manage circuits, protect equipment, and ensure user safety.

[0003] Existing wall-mounted distribution boxes are typically mounted on fixed brackets or mounting frames using multiple bolts. While this installation method is common and reliable, the use of multiple bolts makes disassembly and maintenance inconvenient. For example, a wall-mounted distribution box disclosed in patent CN219833445U, which is designed to be easy to install, incorporates both a fixed unit and a sliding unit, but still requires multiple bolts (such as fastening bolts, connecting bolts, and fixing bolts) for fixation. During installation, the bolt holes need to be precisely aligned, and tools (such as wrenches and screwdrivers) are used for tightening. However, once the distribution box is fixed with multiple bolts, disassembly and maintenance require unscrewing each bolt individually, which is inconvenient and presents problems of complex installation and inconvenient disassembly.

[0004] Therefore, it is necessary to invent a wall-mounted distribution box that is easy to install and remove to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wall-mounted distribution box that is easy to install and disassemble, so as to solve the problem of inconvenient installation and disassembly in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wall-mounted distribution box that is easy to assemble and disassemble, comprising a mounting bracket and a distribution box body. A support plate is provided below the front side of the mounting bracket, and the distribution box body is provided above the support plate. A plug rod is provided on the bottom surface of the distribution box body. A slot is provided at the contact position between the top surface of the support plate and the plug rod. A left movable frame and a right movable frame are respectively provided on the front side of the mounting bracket. A fixing plate is installed on the front wall of both the left and right movable frames. A limit block is provided on the side wall of the fixing plate near the outer wall of the distribution box body. A limit groove is provided at the contact position between the side wall of the distribution box body and the limit block.

[0007] Preferably, there are four plugs and slots, and the four plugs and slots are matched with each other. The tight cooperation of the four plugs and slots can make the power distribution box body stably installed on the support plate.

[0008] Preferably, a first heat dissipation hole is provided at the bottom of the distribution box body, and a second heat dissipation hole is provided on the support plate. Multiple first and second heat dissipation holes are provided, and the positions of the multiple first heat dissipation holes correspond to the positions of the second heat dissipation holes. Dustproof nets are provided inside the multiple first and second heat dissipation holes. Through the cooperation of the multiple first and second heat dissipation holes, the heat generated inside the distribution box body can be effectively discharged, and the dustproof nets can effectively block dust and debris from the external environment to prevent dust and debris from entering the distribution box body.

[0009] Preferably, a sliding rod is provided on the lower rear side of the loading bracket, a servo motor is provided on the front side wall of the loading bracket, a transmission mechanism is provided between the servo motor and the bidirectional lead screw, and a bidirectional lead screw is provided on the upper rear side of the loading bracket and passes through the left and right moving frames. The servo motor, as a power source, can accurately control the rotation speed and direction of the bidirectional lead screw, thereby achieving precise control of the left and right moving frames.

[0010] Preferably, the left and right movable frames are located on the left and right sides of the distribution box body, respectively, to facilitate the installation and disassembly of the distribution box body.

[0011] Preferably, the transmission mechanism consists of two gears and a belt, with the belt tensioned on the two gears. One gear is located on the output shaft of the servo motor, and the other gear is located on one end of the bidirectional lead screw. The transmission mechanism converts the rotational motion of the servo motor into the linear motion of the bidirectional lead screw, thereby driving the left and right moving frames.

[0012] Preferably, two fixing clamps are provided, and the two fixing clamps are symmetrical about the distribution box body. Anti-slip pads made of rubber are pasted on the side walls of the fixing clamps. The fixing clamps and anti-slip pads can effectively clamp and fix the distribution box body.

[0013] Preferably, the limiting groove is formed on the left and right sides of the outer wall of the distribution box body, and the limiting groove is matched with the limiting block, so as to accurately position and limit the installation position of the distribution box body.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention utilizes a designed plug-in and slot structure, allowing the distribution box body to be stably and quickly mounted on a support plate. Simultaneously, the cooperation of a servo motor, transmission mechanism, and bidirectional lead screw enables easy clamping and loosening of the distribution box body by the left and right moving frames. Furthermore, the tight fit between the four plug-in rods and slots, along with the use of fixing plates and anti-slip pads, ensures that the distribution box body is not prone to shaking or falling off during installation. This automated clamping mechanism further simplifies the assembly and disassembly process, allowing users to quickly install and remove the distribution box without tools, making operation simple and convenient.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The wall-mounted distribution box shown includes a mounting bracket 1 and a distribution box body 3. A support plate 2 is provided on the lower front side of the mounting bracket 1, and the distribution box body 3 is provided on the upper side of the support plate 2. A plug rod 4 is provided on the bottom surface of the distribution box body 3. A slot 5 is provided at the contact position between the top surface of the support plate 2 and the plug rod 4. A left movable frame 8 and a right movable frame 9 are respectively provided on the front side of the mounting bracket 1. A fixing plate 14 is installed on the front wall of both the left movable frame 8 and the right movable frame 9. A limit block 16 is provided on the side wall of the fixing plate 14 near the outer wall of the distribution box body 3. A limit groove 17 is provided at the contact position between the side wall of the distribution box body 3 and the limit block 16.

[0025] There are four plug rods 4 and four slots 5. The four plug rods 4 and slots 5 are matched. A first heat dissipation hole 6 is opened at the bottom of the distribution box body 3. A second heat dissipation hole 7 is opened on the support plate 2. There are multiple first heat dissipation holes 6 and second heat dissipation holes 7. The positions of multiple first heat dissipation holes 6 correspond to the positions of second heat dissipation holes 7. Dustproof nets are installed inside the multiple first heat dissipation holes 6 and second heat dissipation holes 7.

[0026] The shape and size of the slot 5 are matched with the plug 4, so that the plug 4 can be smoothly inserted into the slot 5, realizing the quick connection between the distribution box body 3 and the support plate 2. The positions of the first heat dissipation hole 6 and the second heat dissipation hole 7 are completely corresponding, forming an effective heat dissipation channel. The dustproof net can prevent dust and debris from entering the inside of the distribution box from the first heat dissipation hole 6 and the second heat dissipation hole 7.

[0027] A sliding rod 11 is provided on the lower rear side of the loading bracket 1. A servo motor 12 is provided on the front wall of the loading bracket 1. A transmission mechanism 13 is provided between the servo motor 12 and the bidirectional lead screw 10. A bidirectional lead screw 10 is provided on the upper rear side of the loading bracket 1 and passes through the left moving frame 8 and the right moving frame 9. The left moving frame 8 and the right moving frame 9 are located on the left and right sides of the distribution box body 3, respectively. The transmission mechanism 13 consists of two gears and a belt. One belt is tensioned on the two gears. One gear is located on the output shaft of the servo motor 12, and the other gear is located on one end of the bidirectional lead screw 10. Two fixing plates 14 are provided. The two fixing plates 14 are symmetrical about the distribution box body 3. Anti-slip pads 15 are attached to the side walls of the fixing plates 14. The anti-slip pads 15 are made of rubber. Limiting grooves 17 are opened on the left and right sides of the outer wall of the distribution box body 3. The limiting grooves 17 are matched with the limiting blocks 16.

[0028] The left and right movable frames 8 and 9 are connected to the loading bracket 1 by sliding to ensure smooth movement. The left and right movable frames 8 and 9 can provide uniform clamping force to the distribution box body 3 on the mounting plate 2. The anti-slip pad 15 has good elasticity and friction, which can closely fit the outer wall of the distribution box body 3 to prevent the distribution box body 3 from sliding or shaking during installation. When the fixing clamp 14 clamps the distribution box body 3, the limiting block 16 will be embedded in the limiting groove 17 to accurately position and limit the installation position of the distribution box body 3, further ensuring that the distribution box body 3 will not shift or shake during installation.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, the loading bracket 1 is securely installed on the wall or other supporting structure using multiple fixing bolts. Then, the distribution box body 3 is lifted so that the insertion rod 4 on its bottom surface is aligned with the slot 5 on the support plate 2. The distribution box body 3 is then smoothly placed on the support plate 2, ensuring that the insertion rod 4 is smoothly inserted into the slot 5 to achieve initial fixation. Then, the servo motor 12 is started. The servo motor 12 drives the bidirectional lead screw 10 to rotate through the transmission mechanism 13. As the bidirectional lead screw 10 rotates, the left moving frame 8 and the right moving frame 9 move smoothly towards the distribution box under the guidance of the sliding rod 11. As the electrical box body 3 moves, when the fixed clamping plates 14 on the left moving frame 8 and the right moving frame 9 come into contact with the outer wall of the electrical box body 3, the continued rotation of the bidirectional lead screw 10 will cause the fixed clamping plates 14 to gradually clamp the electrical box body 3. During the process of the fixed clamping plates 14 clamping the electrical box body 3, the limiting block 16 will gradually embed into the limiting groove 17 on the outer wall of the electrical box body 3. When the limiting block 16 is fully embedded in the limiting groove 17, the installation position of the electrical box body 3 is precisely positioned and limited to ensure that there is no offset or shaking. Finally, the power supply of the servo motor 12 is disconnected to complete the installation operation.

[0031] When it is necessary to disassemble the power distribution box body 3, the servo motor 12 is started, and the bidirectional lead screw 10 is driven to rotate in the reverse direction through the transmission mechanism 13. As the bidirectional lead screw 10 rotates in the reverse direction, the left moving frame 8 and the right moving frame 9 move smoothly away from the power distribution box body 3 under the guidance of the sliding rod 11. When the fixing clamp 14 on the left moving frame 8 and the right moving frame 9 gradually loosens the power distribution box body 3, the limit block 16 will also gradually exit from the limit groove 17. After the fixing clamp 14 completely loosens the power distribution box body 3, the power distribution box body 3 can be lifted smoothly. Lifting the power distribution box body 3 upwards allows the plug 4 to be smoothly pulled out of the slot 5. Through the above steps, the disassembly and assembly of the power distribution box body 3 can be easily realized without the need for cumbersome fixing and disassembly work using multiple bolts, thus improving work efficiency and convenience.
