Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more specifically, to a distribution box equipped with positioning and mounting components. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. The massive parameters on the distribution box data generally constitute a low-voltage distribution box. According to the electrical wiring requirements, switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or panel to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by manual or automatic switches.

[0003] In the prior art, a positioning and installation-compatible distribution box, with publication number CN223378672U, includes a positioning base, a housing assembly, a door panel, a mounting support plate assembly, a mounting frame, and a drainage top. Above the positioning base is a housing assembly forming the distribution box frame. The housing assembly includes a back panel and side panels. A door panel for cooperation with the housing assembly is located at the front of the housing assembly. Above the housing assembly and door panel is a drainage top for positioning in cooperation with the positioning base. Two sets of side panels are provided, and between the two sets of side panels is a mounting support plate assembly for enhancing the structural stability of the distribution box. The mounting support plate assembly includes a primary folded edge support plate and a secondary folded edge support plate. Between the primary and secondary folded edge support plates is a mounting frame for installing power distribution components. This utility model, by disassembling the distribution box into different parts, facilitates disassembly and transportation. During installation, the housing assembly and the mounting support plate assembly can be accurately positioned using the positioning base and the drainage top.

[0004] However, while existing distribution boxes can be assembled and used relatively well, and can be installed on walls or floors according to the needs of the usage scenario, the assembly method of a single distribution box is relatively fixed. This limits the flexibility of switching between different assembly methods on a single distribution box, reducing its adaptability to different scenarios. Furthermore, the pre-positioning of the distribution box to the installation location is not precise, increasing the tediousness of assembly for installers and reducing efficiency, thus failing to meet user needs. Therefore, we propose a distribution box with positioning and installation components. Summary of the Invention

[0005] To address the problems mentioned in the background, the present invention provides a distribution box equipped with positioning and installation components. This solves the problems mentioned in the background art, such as the fixed assembly method of existing distribution boxes, the low usability of switching between different assembly methods on a single distribution box, the reduced flexibility of switching the distribution box in different scenarios, and the low pre-positioning of the distribution box with the installation location, which increases the cumbersome assembly process for installers.

A connecting seat 5 is fixedly connected to the bottom of the distribution box body 4. A mounting plate 6 is mounted on the outer wall of the connecting seat 5. A support seat 7 is mounted on the bottom of the mounting plate 6. The back of the connecting frame 3... A slot 8 is provided at the connection point with the mounting bracket 2. A sliding rod 9 that is inserted into the wall 1 is slidably connected to the back of the connecting frame 3.

A first threaded rod 11 is rotatably connected to the outer wall of the threaded slide rod 13, and a first knob 12 is fixedly connected to one end of the first threaded rod 11. A fixing groove 14 is provided at the connection between the inner side wall of the mounting bracket 2 and the threaded slide rod 13. Two sets of first threaded rods 11 are provided, and the two sets of first threaded rods 11 rotate in opposite directions. A rotating rod 30 is rotatably connected to the outer wall of the lifting block 27, and a telescopic rod 33 is fixedly connected to the outer wall of the sliding insert rod 9. When it is necessary to install the distribution box... When installed on a wall, the distribution box is pre-installed on the wall by inserting the sliding rod 9 into the positioning slot 10. The mounting bracket 2 and the connecting frame 3 are then engaged on the wall by inserting the positioning rod 15 into the slot 16, which improves the stability of the distribution box on the wall. When the distribution box needs to be installed on a cast-in-place mounting base, the telescopic movement of the assembly rod 41 improves the effect of changing the distribution box from a wall-mounted installation to a ground-mounted installation. The connection between the assembly rod 41 and the assembly slot 42 allows the mounting plate 6 to engage with the connecting seat 5. With the cooperation of the positioning bolt 31 and the positioning nut 32, the distribution box can be conveniently positioned and installed on the ground.

[0042] like Figure 4 and Figure 5 As shown, a second nut 25 is provided on the outer wall of the connecting frame 3, and a second bolt 26 is threadedly connected to the inner wall of the second nut 25. One end of the second bolt 26 is rotatably connected to a lifting block 27 that is slidably connected to the outer wall of the connecting frame 3. A lifting groove 28 is provided at the connection between the outer wall of the connecting frame 3 and the lifting block 27.

[0043] like Figure 1 , Figure 3 and Figure 7 As shown, the outer wall of the support base 7 is cast with a positioning bolt 31 that slides and connects with the outer wall of the mounting plate 6, and the outer wall of the positioning bolt 31 is threaded with a positioning nut 32 that fits against the top of the mounting plate 6.

[0044] like Figures 9-14 As shown, a second threaded rod 34 is rotatably connected to the outer wall of the connecting seat 5. A second knob 35 is fixedly connected to one end of the second threaded rod 34. A threaded slider 36, which is slidably connected to the outer wall of the connecting seat 5, is threadedly connected to the outer wall of the second threaded rod 34. A swing rod 37, which is rotatably connected to the inner wall of the connecting seat 5, is slidably connected to the outer wall of the threaded slider 36. A turntable 39, which is rotatably connected to the inner wall of the connecting seat 5, is fixedly connected to the rotation center of the swing rod 37 via a rotating shaft. A rotating rod 40 is rotatably connected to the outer wall of the turntable 39. Two sets of rotating rods 40 are provided, and the positions of the two sets of rotating rods 40 are equidistantly distributed about the rotation center of the turntable 39. The rotating rods 40 and the assembly rods 41 are arranged in a one-to-one correspondence. One end of the rotating rod 40 is rotatably connected to a part that is slidably connected to the outer wall of the connecting seat 5. The assembly rod 41 and the connection between the outer wall of the swing rod 37 and the threaded slider 36 are provided with a limiting groove 38, and the limiting groove 38 is set on the lifting path of the conversion rod 21. The connection between the outer wall of the connecting seat 5 and the swing rod 37 is provided with a connecting groove 43, and the connection between the outer wall of the mounting plate 6 and the assembly rod 41 is provided with an assembly groove 42. When the positioning rod 15 slides out of the slot 16, the rotation connection of the pulling rod 17 and the cooperation connection of the connecting block 18 and the lifting rod 19 drive the conversion rod 21 to rise from the limiting groove 38, so that the conversion rod 21 disengages from the limiting groove 38. Under the drive rotation of the swing rod 37, the assembly rod 41 extends out of the connecting seat 5 and inserts into the assembly groove 42, improving the effect of the distribution box switching between wall and ground.

[0045] Working principle:

[0046] like Figure 1-14As shown, when the distribution box needs to be installed and used, and it needs to be positioned and assembled on the wall, the mounting bracket 2 is first installed to the wall 1 with bolts, and the connecting frame 3 is sleeved on the back of the distribution box body 4. The first bolt 23 is rotated and, through the limiting action of the first nut 22, the first bolt 23 is inserted into the mounting groove 24, so that the connecting frame 3 and the distribution box body 4 are assembled. The slot 8 is then inserted into the outer wall of the mounting bracket 2. After assembling the wall 1, the mounting bracket 2, and the connecting frame 3, the second bolt 26 is rotated and, through the limiting action of the second nut 25, the lifting block 27 slides along the inner wall of the lifting groove 28, and is then moved by the rotating rod. The rotation connection of 30 drives the sliding rod 9, which is fixedly connected to the telescopic rod 33, to extend and retract, so that the sliding rod 9 is inserted into the positioning groove 10, and the distribution box is pre-positioned and installed on the wall. After the distribution box is pre-positioned, the first knob 12 is rotated, which drives the first threaded rod 11 to rotate. With the first threaded rod 11 rotating in the opposite direction, the two sets of threaded slide rods 13 slide along the inner wall of the fixing groove 14. As the threaded slide rods 13 slide along the inner wall of the fixing groove 14, the threaded slide rods 13 are inserted into the slot 16, and the sliding rod 9 and the wall 1 are locked and fixed under the pre-insertion, so that the distribution box can be conveniently pre-positioned and installed on the wall.

[0047] When the location of the distribution box needs to be changed, and the distribution box is installed on the ground for assembly, the second bolt 26 is rotated in the reverse direction, causing the sliding rod 9, which is fixedly connected to the telescopic rod 33, to retract. This also causes the pulling rod 17 to rotate. With the connecting block 18 and the lifting rod 19 installed by bolts, the lifting rod 19 and the first spring 20 are driven to rise, causing the conversion rod 21 to gradually rise and disengage from the limiting groove 38. At the same time, the mounting plate 6 is inserted into the outer wall of the connecting seat 5, and the second knob 35 is rotated. Through the rotation of the second threaded rod 34, the threaded slider 36 moves along the outer wall of the connecting seat 5 and the limiting groove 38. The internal synchronous sliding mechanism drives the swing rod 37 to rotate. The rotation of the swing rod 37, through the rotation of the turntable 39, drives the assembly rod 41, which is rotatably connected to one end of the rotating rod 40, to slide along the outer wall of the connecting seat 5 for centering. This allows the assembly rod 41 to be inserted into the assembly slot 42, pre-assembling the mounting plate 6 and the connecting seat 5. After assembling the mounting plate 6 and the connecting seat 5, the mounting plate 6 is inserted into the positioning bolt 31 outside the support seat 7. Through the cooperation of the positioning nut 32 and the positioning bolt 31, the mounting plate 6 and the support seat 7 are assembled and used, enabling the distribution box to be installed and used on the ground, improving the efficiency of switching between wall and ground assembly and use of the distribution box.
