[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present application separately fixes multiple grounding wires and multiple electric wires through a conductor structure, a fixing frame, elastic gas storage member 1 and elastic gas storage member 2 are arranged inside the box to prevent insects and dust from entering the box through the gap between the door body and the box body, and the gas stored in the elastic gas storage member 1 and the elastic gas storage member 2 utilizes the force generated by closing the door body to drive the expansion sealing structure to work. The expansion sealing structure completely fixes the multiple grounding wires and multiple electric wires inside the conductor structure, and at the same time isolates the inside of the box from the outside world, preventing insects and dust from entering the box through the two wiring grooves leaving the inside of the box where the multiple grounding wires and multiple electric wires are laid, thereby ensuring the safety of electrical equipment inside the box.

[0016] 2. During the use of this application, as the door body is closed, the elastic gas storage part three expands inside the rubber tube, filling the inside of the rubber tube, and completely fixing the multiple grounding wires and multiple electrical wires to prevent the external shaking of the multiple grounding wires and multiple electrical wires from affecting the stability of the installation of the multiple grounding wires and multiple electrical wires and electrical components inside the box. The expansion of the elastic gas storage part three cuts off the inside of the rubber tube, separating the inside of the box from the outside, preventing external insects and dust from entering the box through the wiring troughs for laying grounding wires and electrical wires, thereby ensuring the safety of the distribution cabinet.

[0017] 3. In the present application, elastic air storage component 1 and elastic air storage component 2 are fixedly connected to the outside of the fixed frame.

After the other compression telescopic rod is extended to its limit, the air pressure inside the lower air guide cavity reaches the expansion pressure of the elastic air storage component five. The gas inside the lower air guide cavity enters the elastic air storage component five through the air guide groove five, causing the elastic air storage component five to expand and store gas, so that the expansion sealing structure automatically adapts to the state where one wiring trough is used to install wires or two wiring troughs are used to install wires and grounding wires. The air pressure inside the air guide box will surge to the air pressure required for the expansion of the elastic air storage component four. The expansion of the elastic air storage component four relieves the pressure on the air guide box and the elastic air storage component three to avoid damage to the elastic air storage component three, so that the two elastic air storage components three automatically adapt to the state where one wiring trough is used to install wires or two wiring troughs are used to install wires.

[0023] Embodiment 1: A rubber tube 36 is fixedly connected inside the arc-shaped plate 1 34 of the conductor structure 3, and a plurality of wire clamping grooves 37 are provided inside the rubber tube 36, such as Fig. 9 As shown, during the construction process, the staff will leave a certain margin for the wires that need to leave the box 11 through the wiring trough 31, and the wires can move without affecting their installation structure. After the construction is completed, the staff will press multiple wire parts into the wire clamping groove 37 in sequence, and the rubber tube 36 that can be elastically deformed will meet the wires entering the telescopic tube 27. At the same time, the rubber tube 36 clamps the wires through elastic deformation force; Subsequently, the arc plate 2 38 is pressed to one side of the arc plate 1 34, so that the arc plate 2 38 and the arc plate 1 34 form a circular wire duct. Since both sides of the arc plate 1 34 are fixedly connected with the L-shaped plate 1 35, the L-shaped plate 1 35 is fixedly connected with the U-shaped clamping piece 312 inside. Fig. 9 As shown, both sides of the arc plate 2 38 are fixedly connected with L-shaped plates 2 39, and the inside of the L-shaped plates 2 39 is fixedly connected with a clamping plate 313, so when the arc plate 1 34 and the arc plate 2 38 are pressed together, one end of the clamping plate 313 is inserted into the adjacent U-shaped clamping piece 312, and the clamping plate 313 and the U-shaped clamping piece 312 enter an interference fit state, and the arc plate 1 34 and the arc plate 2 38 are installed together; Because reserved grooves 32 are provided on both sides of the wiring groove 31, the circular wire conduit formed by the arc plate 1 34 and the arc plate 2 38 is inserted into the reserved groove 32. In this process, the arc plate 2 38 is controlled to face the expansion sealing structure 2. The reserved groove 32 formed at the bottom of the wiring groove 31 is for the L-shaped plate 1 35 and the L-shaped plate 2 39 to pass through. The bottom and top of the L-shaped plate 2 39 and the L-shaped plate 1 35 are both formed with inclined grooves 310. The setting of the inclined grooves 310 facilitates the L-shaped plate 1 35 and the L-shaped plate 2 39 to enter the reserved groove 32. A limiting frame 33 is provided at the bottom of the two reserved slots 32, and the limiting frame 33 is fixedly connected to the bottom of the wiring slot 31. Figure 4 As shown, when the L-shaped plate 1 35 and the L-shaped plate 2 39 penetrate the reserved groove 32, their movement will be blocked by the limit frame 33. At this time, the arc plate 1 34 and the arc plate 2 38 are installed, and the preliminary limiting of multiple wires is completed. The rubber tube 36 made of elastic and insulating rubber is used to separate the multiple wires to avoid damage caused by friction between the wires or friction with the box body 11, so that the grounding wire and the wires inside the distribution cabinet body 1 pass through the two wiring grooves 31 respectively, ensuring the safety of the distribution cabinet body 1.

[0024] If a wiring groove 31 is not needed, the sealing plug 314 can be directly pressed into the channel formed by the wiring groove 31 and the reserved groove 32. The sealing plug 314 and the box body 11 are in an interference fit state, so the box body 11 is sealed.

[0025] At this time, the outer side of the rubber tube 36 has an arc groove 2 315 which is aligned with the arc groove 1 311 on the outer side of the arc plate 2 38 , and the arc groove 1 311 is aligned with the U-shaped clamping piece 312 in the conductor structure 3 .

[0026] Embodiment 2: A handle 13 is fixedly connected to one side of the door body 12 which is rotatably mounted on one side of the box body 11. The door body 12 can be opened and closed by holding the handle 13. After the staff completes the operation inside the box body 11, the door body 12 is closed. Since a fixing frame 17 is fixedly connected inside the box body 11, an elastic gas storage member 18 and an elastic gas storage member 2 19 are fixedly connected to the outside of the fixing frame 17. Figure 1 As shown, after the door body 12 enters the box body 11, the deformed elastic air storage member 18 and the elastic air storage member 2 19 are blocked between the door body 12 and the fixed frame 17, ensuring the sealing between the door body 12 and the fixed frame 17, preventing water, dust, insects and other debris from entering the box body 11 through the gap between the door body 12 and the box body 11, and ensuring the safety of the electrical components inside the box body 11.

[0027] Then, the baffle 15 is operated. Since a convex groove 16 is provided on one side of the baffle 15, the baffle 15 has two ends that can be inserted into the two support sleeves 14. Figure 1As shown, after the two ends of the baffle 15 are inserted into the two support sleeves 14, the baffle 15 is pushed into the box body 11, and finally the baffle 15 is partially blocked on one side of the door body 12, so that the door body 12 cannot move, and the baffle 15 and the support sleeve 14 are interference fit, and the baffle 15 can only move after being subjected to a certain force; and the shape of the convex groove 16 will cause the baffle 15 to move a certain distance and then resist the support sleeve 14. At this time, there is a cavity between the baffle 15 and the box body 11, which is convenient for pulling the baffle 15.

[0028] Embodiment 3: Both ends of the air guide pipe 21 in the expansion sealing structure 2 are fixedly connected to the fixing frame 17, and a partition plate 24 is fixedly connected inside the air guide pipe 21. The partition plate 24 divides the inside of the air guide pipe 21 into an upper air guide cavity and a lower air guide cavity. Figure 4 As shown; An air guide groove 22 and two air guide grooves 3 25 are provided on the top of the partition plate 24. The air guide groove 22 and the air guide groove 3 25 are both connected to the upper air guide cavity. The air guide groove 22 is arranged on the side of the air guide pipe 21 away from the wire structure 3, and the air guide groove 22 is connected to one end of the elastic air storage member 18. The gas stored in the elastic air storage member 18 can enter the upper air guide cavity through the air guide groove 22, and one end of the telescopic tube 27 is fixedly connected to the air guide pipe 21 and connected to the air guide groove 3 25, and the other end of the telescopic tube 27 is fixedly connected to the air guide box 28. Figure 7 As shown, the air guide channel 1 composed of the air guide groove 1 22, the upper air guide cavity, the air guide groove 3 25, and the telescopic tube 27 connects the elastic air storage member 18 with the air guide box 28; An air guide groove 23 and two air guide grooves 4 26 are arranged at the bottom of the partition plate 24. The air guide groove 23 and the air guide groove 4 26 are connected to the lower air guide cavity. The air guide groove 23 is arranged on the side of the air guide duct 21 away from the wire structure 3. The air guide groove 23 is connected to one end of the elastic air storage part 2 19. The gas stored in the elastic air storage part 2 19 can enter the lower air guide cavity through the air guide groove 23. The air guide groove 4 26 is arranged on the side of the air guide duct 21 close to the wire structure 3. An air guide round tube 1 210 is fixedly connected between the air inlet of the compression and telescopic rod 211 and the air guide duct 21. The air guide round tube 1 210 is arranged on one side of the air guide groove 4 26. Therefore, the air guide channel 2 composed of the air guide groove 23, the lower air guide cavity, the air guide groove 4 26 and the air guide round tube 1 210 connects the elastic air storage part 2 19 with the compression and telescopic rod 211.

[0029] Two return springs 29 are fixedly connected between the air guide box 28 and the air guide duct 21. The two return springs 29 are normally in a contracted state, so the air guide box 28 is limited by the return springs 29 to keep it away from the wire structure 3. At this time, the expansion sealing structure 2 will not affect the normal operation of the wire structure 3.

[0030] During the closing process of the door body 12, the elastic gas storage member 2 19 close to the door body 12 is first pressed by the door body 12, and the gas stored in the elastic gas storage member 2 19 enters the interior of the compression and telescopic rod 211 through the gas guide channel 2, and the compression and telescopic rod 211 stretches to push the gas guide box 28 fixed to the piston end, and the elastic gas storage member 3 212 fixed to the gas guide box 28 enters the interior of the rubber tube 36 through the arc groove 1 311 and the sealing plug 314, and finally one end of the two elastic gas storage members 3 212 enters the interior of the two rubber tubes 36 respectively, and the gas guide box 28 stays in the arc groove 1 311; An air guide groove 5 216 is provided on one side of the air guide duct 21, and an elastic air storage member 5 215 is provided on one side of the air guide groove 5 216. The elastic air storage member 5 215 is fixedly connected to the air guide duct 21, and the air guide groove 5 216 is arranged at the bottom of the partition plate 24 and communicates with the lower air guide cavity. When a sealing plug 314 is installed inside one of the wiring grooves 31, the movement of an air guide box 28 is blocked by the sealing plug 314. At this time, one compression and telescopic rod 211 cannot be extended. At this time, the air pressure inside the lower air guide cavity surges as the door body 12 is closed. After the other compression and telescopic rod 211 is extended to the limit, the air pressure inside the lower air guide cavity reaches the expansion pressure of the elastic air storage member 5 215. The gas inside the lower air guide cavity enters the elastic air storage member 5 215 through the air guide groove 5 216, so that the elastic air storage member 5 215 expands and stores gas, so that the expansion sealing structure 2 automatically adapts to the state where one wiring groove 31 is used to install wires or two wiring grooves 31 are used to install wires and grounding wires. As the door body 12 is closed, when the door body 12 presses the elastic gas storage part 2 19 and then presses the elastic gas storage part 1 18, the gas stored in the elastic gas storage part 18 enters the air guide box 28 through the air guide channel 1. The elastic gas storage part 3 212 fixedly connected to the air guide box 28 is now inside the rubber tube 36. The elastic gas storage part 3 212 expands inside the rubber tube 36 to fill the inside of the rubber tube 36, and the multiple grounding wires and multiple wires are completely fixed to prevent the external shaking of the multiple grounding wires and multiple wires from affecting the stability of the installation of the multiple grounding wires and multiple wires and the electrical components inside the box 11. The expansion of the elastic gas storage part 3 212 cuts off the inside of the rubber tube 36, so that the inside and outside of the box 11 are separated, and external insects and dust are prevented from entering the inside of the box 11 through the wiring trough 31 for laying grounding wires and wires, thereby ensuring the safety of the distribution cabinet 1.

[0031] On one side of the two air guide boxes 28, there is a fixed air guide round pipe 213. Fig.10As shown, one end of the air guide circular tube 213 is fixedly connected to an elastic air storage component 4 214. When a sealing plug 314 is inserted into a wiring trough 31, the expansion space of an elastic air storage component 3 212 is insufficient. At this time, the air pressure inside the air guide box 28 will surge to the air pressure required for the elastic air storage component 4 214 to expand. The expansion of the elastic air storage component 4 214 will relieve the pressure on the air guide box 28 and the elastic air storage component 3 212, avoiding damage to the elastic air storage component 3 212, and allowing the two elastic air storage components 3 212 to automatically adapt to the state where one wiring trough 31 is used to install wires or two wiring troughs 31 are used to install wires.

[0032] In summary, when the present application separately fixes multiple grounding wires and multiple electric wires through the conductor structure 3, a fixing frame 17, an elastic gas storage member 18 and an elastic gas storage member 2 19 are arranged inside the box body 11 to prevent insects and dust from entering the box body 11 through the gap between the door body 12 and the box body 11, and the gas stored in the elastic gas storage member 18 and the elastic gas storage member 2 19 utilizes the force generated by closing the door body 12 to drive the expansion sealing structure 2 to work. The expansion sealing structure 2 completely fixes the multiple grounding wires and multiple electric wires inside the conductor structure 3, and at the same time isolates the inside of the box body 11 from the outside world, so as to prevent insects and dust from entering the box body 11 through the two wiring grooves 31 where the multiple grounding wires and multiple electric wires are laid and leaving the inside of the box body 11, thereby ensuring the safety of the electrical equipment inside the box body 11.

[0033] In addition, such as Figure 1 and Figure 3 As shown, a protective frame 217 is fixedly connected to one side of the air guide duct 21, and the telescopic tube 27, the air guide circular tube 210 and the elastic air storage component 3 212 are all arranged inside the protective frame 217. The protective frame 217 provides protection for the telescopic tube 27 and the air guide circular tube 210 that are not extended and the elastic air storage component 3 212 that is not expanded, so as to prevent the expansion sealing structure 2 from being damaged and leaking during the construction process inside the box body 11 by the staff.

[0034] In addition, the air pressure required for the elastic air storage component three 212 to expand is smaller than the air pressure required for the elastic air storage component four 214 to expand, and the air pressure required for the air guide tube one 210 to extend is smaller than the air pressure required for the elastic air storage component five 215 to expand.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
