[0028] Please see Figures 1-6 A mounting frame structure for a distribution box includes a distribution box body 1 and a bracket box 2. Fixing lugs 3 are fixedly installed on the top and sides of the outer wall of the bracket box 2. A V-shaped guide rail 4 is fixedly installed inside the bracket box 2. A pair of clamping arms 5 are engaged inside the V-shaped guide rail 4. Openings 6 are provided at both corners of the bracket box 2, and one end of each pair of clamping arms 5 extends to the outside of the bracket box 2 through the two openings 6. One end of each pair of clamping arms 5 is bent. A gear 9 is mounted at the center of the V-shaped guide rail 4 via a rotating shaft. A U-shaped block 10 and a toothed rod 11 are fixedly installed at one end of each pair of clamping arms 5. A fixing box 12 is fixedly installed inside the bracket box 2, and push rods 13 are stacked on the outer wall of the toothed rod 11. One end of the rod 13 is provided with a U-shaped groove 14, and one side of the inner wall of the U-shaped groove 14, one side of the toothed rod 11, and one side of the groove of the U-shaped block 10 are all connected to each other by the toothed block and the gear 9. The outer wall of the push rod 13 is fixedly installed with a guide rod 15, and the outer wall of the guide rod 15 is sleeved with a return spring 16. One end of the return spring 16 is fixedly connected to the bottom end of the inner wall of the fixing box 12. One end of the push rod 13 extends to the outer side of the bottom end of the bracket box 2 through the through groove, and one end of the push rod 13 is fixedly installed with a support rod 17. One end of each pair of clamping arms 5 is provided with a clamping block 18, and the vertical ends of the two clamping blocks 18 that are close to each other are both folded. This device can effectively improve the convenience and efficiency of the staff when installing and fixing the main body of the distribution box 1.

[0029] See Figure 3 , Figure 5Each pair of clamping arms 5 has a limiting groove 7 on its outer wall, and a limiting rod 8 is fixedly installed inside each of the two openings 6. The limiting rod 8 is engaged with the inside of the limiting groove 7. When the clamping arm 5 moves, the mutual cooperation between the limiting groove 7 and the limiting rod 8 ensures the stability of the clamping arm 5 during movement. The fixing box 12 is located below the V-shaped guide rail 4. The toothed block rod 11 is stacked on the outer wall of the U-shaped block 10, and the outer wall of the U-shaped block 10 is in contact with the outer wall of the toothed block rod 11. The outer wall of the toothed block rod 11 is in contact with the outer wall of the push rod 13. By setting the positions of the U-shaped block 10, the toothed block rod 11 and the push rod 13, the device has a compact structure and stable operation.

[0030] See Figure 1 , Figure 2 The bracket box 2 is placed at the top of the support rod 17, and the folded edge of the clamping block 18 is engaged with the edges of the outer wall of the main body of the distribution box 1. By placing the bracket box 2 at the top of the support rod 17, the entire mounting frame structure has good load-bearing capacity and stability. At the same time, the folded edge structure of the clamping block 18 is tightly engaged with the edges of the outer wall of the main body of the distribution box 1, which further enhances the fixing effect of the main body of the distribution box 1 in the installation state and prevents it from shifting or falling off due to vibration or external force.

[0031] See Figure 2 , Figure 6 The outer wall of the lateral end of the clamping block 18 has a pair of through holes 19. A pair of positioning lugs 20 are fixedly installed on both sides of the outer wall of the clamping arm 5. An adjusting bolt 21 is fixedly installed on one side of one of the positioning lugs 20 in each group. One end of the adjusting bolt 21 passes through the through hole 19 and extends to the outside of the other positioning lug 20 through a through groove. A locking nut 22 is threaded to one end of the adjusting bolt 21, and one end of the locking nut 22 is tightly fitted to the outer wall of the clamping block 18. The positions of the two positioning lugs 20 are symmetrical with the positions of the through holes 19, and the lateral end of the clamping block 18 is located between the two positioning lugs 20. This structure uses the locking nut 22 to fix the position of the clamping block 18, so that the clamping block 18 can be adjusted and fixed according to different widths of the main body 1 of the distribution box, thereby improving the stability of the overall structure and the reliability of clamping.

[0032] In use: First, the operator fixes the bracket box 2 to the wall using the fixing lugs 3. Then, the main body of the distribution box 1 is inserted into the bracket box 2. Its weight acts on the support rod 17 and drives the push rod 13 to move downward. The toothed block on the inner side of the U-shaped groove 14 on the push rod 13 drives the gear 9 to rotate, thereby driving the U-shaped block 10 and the toothed rod 11 to move in conjunction, causing the clamping arm 5 to close inward along the V-shaped guide rail 4. During this process, the limiting groove 7 and the limiting rod 8 cooperate to ensure that the movement of the clamping arm 5 is smooth and reliable. Finally, the clamping block 18 automatically clamps the main body of the distribution box 1. At the same time, the adjusting bolt 21 and the locking nut 22 can be adjusted according to the size of the distribution box to improve versatility and clamping reliability, thus completing the installation of the main body of the distribution box 1.
