[0002] The current principles for incoming and outgoing lines in distribution cabinets are: in from top and out from bottom; in from bottom and out from top; in from side and out from top; in from side and out from bottom. Due to the possibility of dust or small animals entering, distribution cabinets generally need to be sealed.

[0003] The announcement number is: CN219937644U, which discloses "a sealing structure for inlet and outlet lines of a power distribution cabinet, which relates to the technical field of power distribution cabinets. It includes a limit card plate, which is used to clamp and fix the wires, and assemble a fixing device. The utility model realizes that the gap between the cable and the cabinet can be quickly sealed when the equipment is in use by setting a sealing gasket, a first sealing gasket, a second sealing gasket and a third sealing gasket";

[0004] There are still certain disadvantages in use. Several sealing gaskets are used to seal the wires. However, there are many types of electronic components inside the distribution cabinet, and the wire diameters used are also different. When sealing with sealing gaskets, it is not convenient to clamp and fix wires of various diameters at the same time, and the sealing effect is poor for wires with smaller diameters.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1.

The sealing strip increases the sealing between the sealing plate and the distribution cabinet. When the auxiliary airbag expands, the annular sealing gasket is pushed inward to fit the wires, thereby improving the sealing effect on different wires, thereby facilitating the rapid replacement of damaged sealing sheets and annular sealing gaskets, making it easy to repair.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In an embodiment of the utility model, a distribution cabinet inlet and outlet line sealing structure includes a sealing plate 1, a plurality of wire grooves 102 are equidistantly provided on one side surface of the sealing plate 1, a storage groove 103 is provided on the inner surface of the wire groove 102, an air inlet groove 2 is provided on one end surface of the sealing plate 1, a one-way valve assembly 4 is fixedly provided inside the air inlet groove 2, an annular air bag 3 is movably provided inside the storage groove 103, and auxiliary air bags 305 are movably provided on both sides of the annular air bag 3 inside the storage groove 103.

[0026] Embodiment 1

[0027] like Figure 2 and 3As shown, in the present embodiment, an air dividing groove 202 is opened inside the sealing plate 1, and the air dividing groove 202 is respectively connected with a plurality of receiving grooves 103, and a connecting pipe 203 is fixedly installed at the connection between the air dividing groove 202 and the receiving groove 103, and an air inlet pipe 201 is fixedly installed on the surface of one end of the sealing plate 1 at the outside of the air inlet groove 2; an interface 301 is fixedly embedded and installed on the outer surface of the annular airbag 3, and the interface 301 is movably engaged and connected with the connecting pipe 203, and spacer rings 302 are fixedly installed on both sides of the annular airbag 3 inside the receiving groove 103, and the auxiliary airbag 305 and the annular airbag 3 are connected via a connecting hose 306.

[0028] In this embodiment, for the sake of clarity of description, the interface 301 is movably engaged with the connecting tube 203, and compressed air is injected into the air inlet pipe 201. The compressed air is dispersed into the interior of multiple annular airbags 3 through the air distribution grooves 202, and then distributed into the interior of the auxiliary airbags 305 through the connecting hose 306, so that both are expanded. The spacer ring 302 limits the expansion range of the annular airbag 3 to both sides, so that it expands inward and sticks to the surface of the wire, thereby sealing the wire through the expansion of the annular airbag 3, and at the same time, the expansion of the auxiliary airbag 305 pushes the annular sealing pad 304 for further sealing, thereby facilitating the clamping and fixation of wires of various diameters at the same time, thereby improving the sealing effect for wires with smaller diameters.

[0029] like Figure 5 As shown, in this embodiment, the one-way valve assembly 4 includes a sealing ring 401 and a sealing top plate 402. The sealing ring 401 is fixedly installed on the inner surface of the air inlet groove 2, and the sealing top plate 402 is movably embedded in the inner surface of the sealing ring 401. A push rod 403 is fixedly installed on one side surface of the sealing top plate 402; a spring 404 is movably sleeved on the outer side of the push rod 403, and a fixing frame 405 is fixedly installed inside the air inlet groove 2.

The two ends of the spring 404 are respectively fixedly connected to the fixing frame 405 and the sealing top plate 402.

[0030] In specific implementation, when compressed air is injected into the air inlet groove 2, the sealing top plate 402 moves and separates from the sealing ring 401 to allow air to be injected. After the air injection is completed, the spring 404 pushes the sealing top plate 402 to reset and close the one-way valve assembly 4 to prevent the compressed air from flowing out, thereby improving the air tightness.

[0034] During specific implementation, the sealing plate 1 is fixed to the incoming line of the distribution cabinet by fasteners passing through the stepped hole 101, and the sealing strip 104 increases the sealing between the sealing plate 1 and the distribution cabinet. When the auxiliary airbag 305 expands, the annular sealing gasket 304 is pushed inward to fit the wires, thereby improving the sealing effect on different wires, thereby facilitating the rapid replacement of damaged sealing sheets 303 and annular sealing gaskets 304, making them easy to maintain.
