Description

Technical Field

[0001] The utility model relates to the field of distribution cabinet sealing, in particular to a distribution cabinet with an inlet and outlet wire sealing structure. Background Technique

[0002] When the distribution cabinet is in use, it is necessary to route the cables in and out. The existing routing mostly passes through the wire holes on the surface of the distribution cabinet for routing, and then uses fireproof mud for sealing.

[0003] However, since the chemical components inside the fireproof mud will undergo oxidation reactions with oxygen and water in the air after long-term use, when the water content of the fireproof mud is too high or the humidity in the environment is relatively high, the water will erode the fireproof mud, resulting in the gradual destruction of its structure and the loss of its original sealing performance. At the same time, the melted fireproof mud is not easy to clean and replace, and it is more troublesome when new cables need to be installed and replaced.

[0004] Therefore, the utility model provides a distribution cabinet with an inlet and outlet wire sealing structure to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides a power distribution cabinet with an in-out wire sealing structure, as Figures 1-5 shown. The power distribution cabinet with an in-out wire sealing structure includes a cabinet body 1, a mounting plate 2 fixedly arranged on one side of the cabinet body 1, wire passing holes respectively opened on the cabinet body 1 and the mounting plate 2, a wire passing tube 21 horizontally penetrating through the cabinet body 1 and the mounting plate 2 in sequence and fixedly connected to the wire passing holes for wire routing, and a sealing mechanism 3 arranged on the cabinet body 1 for wire routing. The sealing mechanism 3 includes an airbag 31 arranged inside the wire passing tube 21 for sealing wire routing, a disassembly and assembly component 32 arranged on the wire passing tube 21, an inflatable tube 33 arranged on one side of the wire passing tube 21 and communicated with the airbag 31, a micro air pump 34 fixedly installed at the end of the inflatable tube 33 far from the airbag 31 for inflating the airbag 31, an installation box 35 fixedly installed on the cabinet body 1 at a position corresponding to the lower part of the wire passing tube 21 and fixedly connected to the bottom of the micro air pump 34, and an adjusting component 36 arranged inside the installation box 35 for puncturing the airbag 31.

[0032] During use, the cables inside the cabinet body 1 are passed through the cable conduit 21 on the mounting plate 2. To ensure the sealing performance during cable passing, the sealing mechanism 3 can be used to seal the cable conduit 21 at the inlet and outlet. First, the airbag 31 is installed inside the cable conduit 21 by using the disassembly and assembly component 32. Then the cable is passed through the center of the airbag 31. Next, the micro air pump 34 is started to inflate the airbag 31 through the air charging pipe 33, so that it is clamped inside the cable conduit 21. When the airbag 31 bulges, the seal between the cable and the cable conduit 21 is achieved. When it is necessary to replace the airbag 31 or change the cable, the fixing needle 361 inside the installation box 35 can be adjusted by using the adjustment component 36 to puncture the airbag 31 and remove it, thus facilitating the replacement of the cable.

[0033] Specifically, the disassembly and assembly component 32 includes a snap ring 321 hinged on the cable conduit 21, adjusting rectangular plates 322 and fixed rectangular plates 323 symmetrically and fixedly arranged on the snap ring 321 and the cable conduit 21 respectively, a plug 324 fixedly arranged on the fixed rectangular plate 323, a slot opened on the adjusting rectangular plate 322, and a limiting block 325 rotatably arranged on the plug 324. The slot is inserted with the plug 324. When it is necessary to disassemble and assemble the airbag 31, the disassembly and assembly component 32 can be used to open the port of the cable conduit 21. By rotating the limiting block 325 to the horizontal position so that it coincides with the plug 324, it is convenient to rotate the adjusting rectangular plate 322 to separate it from the fixed rectangular plate 323, achieving the effect of rotating the snap ring 321 to open the snap ring 321, facilitating the removal of the internal airbag 31. At this time, a new airbag 31 or cable is installed and inserted. After replacement, the snap ring 321 is rotated to be clamped with the cable conduit 21, the adjusting rectangular plate 322 is connected to the fixed rectangular plate 323, and the plug 324 and the limiting block 325 pass through the adjusting rectangular plate 322. To prevent the snap ring 321 from slipping, the limiting block 325 can be rotated to the vertical position to achieve the effect of limiting and fixing.

[0034] Furthermore, the adjustment component 36 includes a fixing needle 361 arranged below the airbag 31, a connecting circular plate 362 fixedly arranged at the bottom of the fixing needle 361, and a telescopic spring 363 fixedly installed at the bottom of the connecting circular plate 362. The bottom of the telescopic spring 363 is fixedly connected to the installation box 35. The adjustment component 36 also includes a limiting component 364 arranged on the installation box 35 for limiting the telescopic spring 363. When it is necessary to replace the airbag 31, the position of the fixing needle 361 can be adjusted by using the adjustment component 36 first, so that the telescopic spring 363 drives the connecting circular plate 362 and the fixing needle 361 to move upward to puncture the airbag 31, facilitating the subsequent removal.

[0035] Further, the limiting component 364 includes an adjusting plate 3641 fixedly arranged on the side of the connecting circular plate 362 away from the snap ring 321, a notch 3642 formed on the side of the mounting box 35 close to the adjusting plate 3641, and a fixing plate 3643 fixedly mounted on the side of the adjusting plate 3641 away from the connecting circular plate 362. The adjusting plate 3641 is slidably mounted in the notch 3642, and the fixing plate 3643 is located on the side of the notch 3642 away from the adjusting plate 3641. The limiting component 364 further includes insertion holes 3644 respectively formed in the fixing plate 3643 and the mounting box 35, and an insertion rod 3645 that sequentially passes through the fixing plate 3643 and the mounting box 35 horizontally and is inserted into the insertion holes 3644. In order to prevent the airbag 31 from being punctured during use, the position of the fixing needle 361 can be limited by the limiting component 364. When the airbag 31 needs to be used, first move the adjusting plate 3641 downward along the notch 3642 on the mounting box 35 to drive the top fixing needle 361 away from the airbag 31. At this time, insert the insertion rod 3645 into the insertion holes 3644 on the side surfaces of the fixing plate 3643 and the mounting box 35 to achieve the limitation of the fixing plate 3643, and further complete the limitation of the fixing needle 361.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
