[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0029] A cable branch box door sealing structure includes a box body 1, a box opening 2, and a box door 3. The box door 3 is used to open and close the box opening 2. A hinge 4 is provided between the box body 1 and the box door 3. A buffer frame 5 is provided on the inner side of the box opening 2. The buffer frame 5 is square and has a buffer groove 6. A buffer rubber 8 is provided at the bottom of the buffer groove 6. The buffer rubber 8 is only provided in the buffer groove 6 on the upper and lower sides. Buffer blocks 7 that are adapted to the buffer groove 6 are provided on the inner sides of the upper and lower sides of the box door 3. The buffer blocks 7 are made of... The door 3 is bent into one piece and protrudes. When the door 3 is closed, the buffer block 7 abuts against the buffer rubber 8. Adjustable buffer components 9 are provided on the left and right sides of the door 3. The adjustable buffer components 9 abut against the inner wall of the buffer frame 5. Through the cooperation between the buffer rubber 8 and the buffer block 7, and the abutment between the adjustable buffer components 9 and the inner wall of the buffer frame 5, the impact force between the door 3 and the box body 1 is reduced when the cable branch box is closed, the vibration is reduced, and the door 3 and the box body 1 are not easily deformed. At the same time, the sealing between the door 3 and the box body 1 is increased.

[0030] The adjustable buffer assembly 9 includes a rubber plate 10, a base plate 11, and an adjusting member 12. The rubber plate 10 is fixedly mounted on the base plate 11. A bent flap 13 is provided on the side of the door 3. The adjusting member 12 fixes the base plate 11 and the rubber plate 10 on the flap 13, separating the buffer rubber 8 on the top and bottom of the door frame from the rubber plate 10 on the side. This makes it easier to replace and install the buffer rubber 8 and the rubber plate 10. When a rubber wears out, the rubber at that location can be directly replaced. During installation, only individual installation is required, without considering the installation positions of other rubbers, thus making installation more convenient.

[0031] The adjusting component 12 includes an adjusting knob 14 and a fixing knob 15. The adjusting knob 14 and the fixing knob 15 have the same structure and are both bolts. The flip plate 13 has a through hole 16 and a through hole 17. Nut 18 and nut 19 are fixedly installed inside the through hole 16 and the through hole 17, respectively. The rubber plate 10 has several grooves 20. The bottom of the base plate 11 relative to the groove 20 has a through hole 21. The adjusting knob 14 is set in the groove 20 and passes through the through hole 16 and the through hole 21 and is threadedly connected to nut 18. The fixing knob 15 is set inside the flip plate 13. The fixing knob 15 is threadedly engaged with nut 19 and abuts against the inside of the base plate 11. By adjusting the knob 14 and fixing the knob 15, the rubber plate 10 and the base plate 11 are clamped from both sides of the flip plate, so that the rubber plate 10 and the base plate 11 can be adjusted and set on the flip plate 13. This allows the distance between the rubber plate 10 and the side end face of the buffer groove 6 to be adjusted to ensure sealing.

[0032] During installation, first, adjust the knob 14 and nut 18 to pre-install the rubber plate 10 and base plate 11 on the outside of the flip plate 13, leaving a gap between the base plate 11 and the flip plate 13. Then, screw the fixing knob 15 into the nut 19 from the inside, so that the bottom of the fixing knob 15 abuts against the base plate 11, thus completing the installation of the base plate 11. When it is necessary to adjust the position of the rubber plate 10, rotate the adjustment knob to control the gap between the base plate 11 and the flip plate 13, move the rubber plate 10 to the appropriate position, and tighten the fixing knob 15.

[0033] The top side of the buffer block 7 is provided with a slope 22, and the buffer rubber 8 is L-shaped and has a slope 23. The slope 22 and the slope 23 cooperate with each other. By setting the buffer rubber plate 10 to be L-shaped, and through the cooperation between the slope 22 and the slope 23, the front end face and the top end face of the buffer block 7 are sealed with the buffer rubber 8, thereby further increasing the sealing performance.

[0034] The door 3 includes a left door 24 and a right door 25. The left door 24 is provided with a pressure groove 26, and a second buffer rubber 27 is provided inside the pressure groove 26. The end of the right door 25 is provided with a second buffer block 28. When the right door 25 presses down on the left door 24, the second buffer block 28 abuts against the second buffer rubber 27. A locking block is provided inside the right door 25, which can lock it when the right door 25 is closed. The second buffer rubber 27 has the same structure as the first buffer rubber 8, and the second buffer block 28 has the same structure as the first buffer block 7. Both are bent edges of sheet metal to increase the structural strength of the edge of the door 3. The left, right and right doors 25 are provided with reinforcing ribs 29. The reinforcing ribs 29 are located near the middle of the door 3 to increase the structural strength of the central part of the door 3 and prevent the door 3 from deforming under slight external impact.

[0035] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
