Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a comprehensive distribution box with an inlet and outlet protection structure. Background Art

[0002] A distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or screen according to electrical wiring requirements. Distribution boxes are mainly used in residential and industrial areas.

[0003] In the related art, a distribution box includes a box body and a box door, wherein the box door is rotatably connected to the box body, and a through-hole is provided on the box body for incoming or outgoing wires.

[0004] Since distribution boxes are usually installed outdoors, some small animals may climb on the wires or even drill into the box through the holes, affecting the normal use of the distribution box. Summary of the Invention

[0005] In order to improve the problem of small animals drilling into the box through the perforations, the present application provides an integrated distribution box with an inlet and outlet protection structure.

[0006] This application provides a comprehensive distribution box with an inlet and outlet protection structure, which adopts the following technical solutions: A comprehensive distribution box with an inlet and outlet protection structure includes a box body and a box door. The box door is rotatably connected to the box body. The box body is provided with a through-hole for inlet and outlet wires. The box body is provided with a protective tube. The through-hole is located inside the protective tube. A protective film is provided inside the protective tube. The wire passes through the protective film and enters the box body through the through-hole.

[0007] By adopting the above technical solution, a protective tube is set on the box, and the perforation is located in the protective tube, so that the protective tube can protect the wires at the perforation. In addition, the protective film is located in the protective tube, and the wires need to pass through the protective film to enter the box, so that the protective film can reduce the possibility of small animals directly climbing into the box along the wires.

[0008] Optionally, an elastic strip is provided in the protective tube, and a limit strip is provided on one end of the elastic strip. The limit strip bends toward the direction of the wire, and the elastic strip bends toward one side of the protective film; when the elastic strip is located in the protective tube, the limit strip abuts against the wire; when the elastic strip is deformed toward the side away from the protective film, the limit strip squeezes the wire.

[0009] By adopting the above technical solution, an elastic strip is set in the protective tube, and the elastic strip is bent toward one side of the protective film, so that the elastic strip can protect the protective film, reducing the possibility of small animals directly tearing the protective film and entering the perforation. At the same time, the limit strip abuts the wire, so that the limit strip can limit the shaking of the wire at the perforation, reducing the unstable connection of the wire during the process of small animals climbing the wire; when the small animal pushes the protective film, the protective film drives the elastic strip to deform toward the side away from the protective film, so that the elastic strip can deform in the opposite direction. At this time, the elastic strip has one end of the limit strip deformed in the direction away from the wire, and the limit strip is bent toward the direction of the wire, so that the limit strip can squeeze the wire, thereby making the connection between the limit strip and the wire more secure. Since the limit strip squeezes the wire, the limit strip can limit the movement of the elastic strip in the protective tube, reducing the possibility of small animals forcibly passing through the protective tube.

[0010] Optionally, a receiving groove for inserting the elastic strip is provided on the protective tube, and a receiving block is provided on the groove wall of the receiving groove; when the elastic strip is inserted into the receiving groove, the receiving block is located on the side of the elastic strip away from the bottom wall of the receiving groove.

[0011] By adopting the above technical solution, the elastic strip is inserted into the receiving groove, and the receiving block is located on the side of the elastic strip away from the bottom wall of the receiving groove, so that the elastic strip can be stably located in the receiving groove, reducing the possibility of small animals causing the elastic strip to deform and cause the elastic strip to detach from the protective tube, and further increasing the firmness of the connection between the elastic strip and the protective tube.

[0012] Optionally, a stop block is provided on the groove wall of the accommodating groove, and a stop hole for inserting the stop block is opened on the surface of the elastic strip; when the stop block is inserted into the stop hole, the elastic strip is deformed in a direction away from the protective film, and the limiting strip squeezes the wire.

[0013] By adopting the above technical solution, when the elastic strip is deformed in the direction away from the protective film, the end of the elastic strip away from the limit strip moves in the accommodating groove, allowing the stop block to be located in the stop hole, so that the stop block can limit the reset of the elastic strip, so that the elastic strip and the limit strip can keep the wire fixed and the protective tube sealed, and the staff can know whether small animals have entered the protective tube by observing the status of the elastic strip during daily maintenance, so that the staff can check whether the wire has been gnawed by small animals.

[0014] Optionally, a limiting spring piece is provided in the protective tube, the limiting spring piece is located on a side of the protective film away from the elastic strip, and the limiting spring piece abuts against the protective film.

[0015] By adopting the above technical solution, the limiting spring is located on the side of the protective film away from the elastic strip, so that the limiting spring can abut the protective film, so that the limiting spring can limit small animals from pulling the protective film out from the side away from the elastic strip, so that the limiting spring can protect the protective film.

[0016] Optionally, a limiting hole for inserting a limiting spring piece is provided on the elastic strip; when the elastic strip is deformed in a direction away from the protective film, the limiting spring piece is inserted into the limiting hole.

[0017] By adopting the above technical solution, when the elastic strip is deformed in the direction away from the protective film, the limiting spring piece can be inserted into the limiting hole, so that the limiting spring piece can limit the elastic strip from resetting, further increasing the abutment effect of the limiting strip on the wire, and allowing the elastic strip to be stably located in the protective tube, reducing the possibility of the elastic strip detaching from the protective tube.

[0018] Optionally, two connecting blocks are provided in the protective tube, and the two connecting blocks are respectively located on both sides of the wire. A connecting piece is provided on the connecting block, and the connecting piece is bent toward the direction of the wire; when the wire passes through the through hole, the connecting piece abuts the wire.

[0019] By adopting the above technical solution, the connecting blocks are located on both sides of the wire, and the connecting pieces are bent toward the wire, so that both sides of the wire are covered by the connecting pieces, making it difficult for the wire to shake at the perforation.

[0020] Optionally, a connecting strip is provided on the surface of the connecting piece close to the connecting block, and the connecting strip is located on the deformation path of the limiting strip; when the limiting strip squeezes the wire, the limiting strip drives the connecting strip to abut against the wire.

[0021] By adopting the above technical solution, when the limiting bar squeezes the wire, the connecting bar is located on the deformation path of the limiting bar, so that the limiting bar drives the connecting bar to deform, allowing the connecting bar to smoothly abut the wire. The connecting bar, the limiting bar and the connecting piece abut the wire together to achieve covering all sides of the wire, reducing the possibility of small animals tearing the protective film along the wire and the protective film and causing small animals to enter.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The protective tube is set on the box body, and the perforation is located in the protective tube, so that the protective tube can protect the wires at the perforation. In addition, the protective film is located in the protective tube, and the wires need to pass through the protective film to enter the box body, so that the protective film can reduce the possibility of small animals directly climbing into the box body along the wires.

[0023] 2. The elastic strip is set in the protective tube, and the elastic strip is bent toward one side of the protective film, so that the elastic strip can protect the protective film, reducing the possibility of small animals directly tearing the protective film and entering the perforation. At the same time, the limit strip abuts the wire, so that the limit strip can limit the shaking of the wire at the perforation, reducing the unstable connection of the wire during the process of small animals climbing the wire; when the small animal pushes the protective film, the protective film drives the elastic strip to deform toward the side away from the protective film, so that the elastic strip can deform in the opposite direction. At this time, the elastic strip has one end of the limit strip deformed in the direction away from the wire, and the limit strip bends toward the direction of the wire, so that the end of the limit strip away from the elastic strip can squeeze the wire, thereby making the connection between the limit strip and the wire more secure. Since the limit strip squeezes the wire, the limit strip can limit the movement of the elastic strip in the protective tube, reducing the possibility of small animals forcibly passing through the protective tube.

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] Example 1 This embodiment discloses a comprehensive distribution box with an inlet and outlet protection structure. Figure 1 A comprehensive distribution box with an inlet and outlet protection structure includes a box body 1 and a box door 11, and the box door 11 is rotatably connected to the box body 1.

[0028] Reference Figure 2 The housing 1 is provided with a slot 12 for placing power supply components. Multiple perforations 13 are provided on the side of the housing 1 for wire entry and exit. A protective tube 2 is provided on the side of the housing 1, with its opening curved toward the ground. A protective plate 21 is fixedly attached to the outer surface of the protective tube 2, and fasteners 22 are provided on the protective plate 21 to secure the protective plate 21 to the housing 1.

[0029] Reference Figure 3 The fasteners 22 include fastening bolts 221 and fastening nuts 222. A plurality of first through-holes 23 are defined on the surface of the protective plate 21. These first through-holes 23 are arranged in an array along the circumference of the protective tube 2 and are provided for the fastening bolts 221 to pass through. The housing 1 also includes a plurality of second through-holes 231, through which the fastening bolts 221 pass. When the protective tube 2 is aligned with the through-hole 13, the first through-holes 23 align with the second through-holes 231. The fastening bolts 221 then pass through the first and second through-holes 23, 231, and the fastening nuts 222 are then threadedly connected to the fastening bolts 221, completing the installation of the protective plate 21.

[0030] Reference Figure 2 A protective film 24 is fixedly connected to the inner wall of the protective tube 2. The protective film 24 is made of rubber material and can be cut. The wire is inserted into the through hole 13 through the protective film 24 to achieve the installation of the wire on the box body 1.

[0031] The implementation principle of Example 1 is as follows: the worker cuts the protective film 24 and allows the wire to pass through the protective film 24 and be inserted into the through hole 13 to achieve the installation of the wire.

[0032] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that two mounting blocks 3 are integrally formed on the inner wall of the protection tube 2, and the two mounting blocks 3 are symmetrically distributed along the vertical direction of the protection tube 2. A receiving groove 31 is formed on the surface of each mounting block 3 facing the other mounting block 3.

[0033] Reference Figure 6Two elastic strips 32 are provided within the protective tube 2. A limit strip 321 is fixedly connected to one end of each elastic strip 32, and the end of each elastic strip 32, away from the limit strip 321, can be inserted into the receiving groove 31. The elastic strips 32 are elastic and bend toward the protective film 24. The limit strip 321 extends away from the protective film 24 and bends toward the conductor.

[0034] Reference Figure 6 A receiving block 311 is integrally formed on the groove wall of the receiving groove 31 away from the protective film 24, and a stop block 312 is integrally formed on the groove wall of the receiving groove 31 close to the protective film 24. A stop hole 322 is opened on the elastic strip 32 for the stop block 312 to be inserted into.

[0035] Reference Figure 6 When the elastic strip 32 bends toward the protective film 24, the limiting strip 321 contacts the wire. At this point, the elastic strip 32 is located on the side of the receiving block 311 away from the other mounting block 3. When a small animal presses the elastic strip 32, causing it to bend away from the protective film 24, both ends of the elastic strip 32 tilt toward the protective film 24, allowing the limiting strip 321 to squeeze the wire. The end of the elastic strip 32 away from the limiting strip 321 remains within the receiving slot 31, and the stop block 312 is located within the stop hole 322, securing the elastic strip 32 within the receiving slot 31.

[0036] Reference Figure 6 and Figure 7 Two connecting blocks 4 are fixedly connected to the inner wall of the protective tube 2. The two connecting blocks 4 are arranged in the horizontal direction, and the elastic strip 32 is arranged in the vertical direction. A connecting piece 41 is fixedly connected to the surface of the connecting block 4 facing the other connecting block 4. The connecting piece 41 has elastic deformation capability. Both ends of the connecting piece 41 are deformed in the direction of the conductor, that is, the connecting piece 41 can cover both sides of the conductor in the horizontal direction, and the elastic strip 32 can cover both sides of the conductor in the vertical direction. Connecting strips 42 are fixedly connected to both ends of the connecting piece 41. The bending curvature of the connecting strip 42 is different from that of the connecting piece 41. The connecting strip 42 is located on the deformation path of the limiting strip 321.

[0037] Reference Figure 6 and Figure 7 When the elastic strip 32 deforms toward the protective film 24, the connecting piece 41 contacts the wire, while the connecting strip 42 does not. When the elastic strip 32 deforms away from the protective film 24, the limiting strip 321 causes the connecting strip 42 to deform, allowing it to contact the wire. At this time, the connecting piece 41 compresses the wire, securing the wire together with the connecting piece 41, connecting strip 42, and limiting strip 321.

[0038] Reference Figure 6Two stopper springs 33 are fixedly attached to the inner wall of the protective tube 2 and arranged vertically. These two stopper springs 33 are located on the side of the protective film 24 away from the elastic strip 32 and are elastic. They abut the side of the protective film 24 away from the elastic strip 32, preventing small animals from pulling the protective film 24 away from the elastic strip 32.

[0039] Reference Figure 6 The elastic strip 32 has a limit hole 323 formed on its surface for the insertion of the limit spring 33 and the protective film 24. When the elastic strip 32 is deformed toward the conductor, the limit spring 33 drives the protective film 24 toward the elastic strip 32 until one end of the limit spring 33 and a portion of the protective film 24 are inserted into the limit hole 323, thereby preventing the elastic strip 32 from returning to its original position. This allows staff to detect small animals that have penetrated the protective tube 2 during routine inspections, allowing them to check whether the conductors have been gnawed or scratched by small animals.

[0040] The implementation principle of Example 2 is as follows: when the elastic strip 32 is deformed toward the direction of the wire, the limiting strip 321 squeezes the wire, and the limiting spring piece 33 drives the protective film 24 to be inserted into the limiting hole 323, so that the limiting spring piece 33 fixes the elastic strip 32. At this time, one end of the elastic strip 32 moves in the accommodating groove 31, allowing the stop block 312 to be inserted into the stop hole 322, and the elastic strip 32 drives the connecting strip 42 to move, so that the connecting strip 42 can smoothly abut the wire, and the connecting piece 41 squeezes the wire.
