Description

Technical Field

[0001] The utility model is applicable to the technical field of power distribution cabinets, and particularly relates to a cable sealing device for a power distribution cabinet. Background Art

[0002] At present, distribution cabinets are very common in daily life. When the distribution cabinets are in use, animals and dust often enter the interior of the distribution cabinet along the cables, which can easily cause damage to the distribution cabinet. The cable sealing device can well seal the connection position between the cable and the distribution cabinet, thereby protecting the distribution cabinet.

[0003] However, when sealing and protecting the cables in the power distribution cabinet, the sealing pad cannot be adjusted in position during the bonding installation, which results in the inability to fit the cables with different diameters during the stretching adjustment process, thus affecting the protection quality inside the power distribution cabinet. Therefore, we propose a cable sealing device for the power distribution cabinet. Utility Model Content

[0004] The main purpose of the utility model is to provide a cable sealing device for a power distribution cabinet, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cable sealing device for a power distribution cabinet comprises a mounting base, a cabinet body is fixedly mounted on the top surface of the mounting base, a wire threading groove is provided inside the side of the cabinet body, and the number of the wire threading grooves is several groups;

[0007] Guide tubes are vertically fixedly installed on both ends of the cabinet side surface, and the guide tubes are located on both sides of the outside of the threading groove, and an extrusion plate is slidably installed on the inner bottom surface of each guide tube, and a connecting rod is fixedly installed on the outer end surface of each extrusion plate, and a connecting plate is fixedly installed between the top ends of the side edges of each two groups of connecting rods, and a sealing gasket is detachably bonded to the bottom surface of each connecting plate;

[0008] A push spring is movably sleeved inside each guide tube, and the bottom surface of the push spring is movably fitted to the outer surface of the extrusion plate.

[0009] By adopting the above technical solution, the sealing gasket and the extrusion plate that can be inside the guide tube are transmission-connected through the connecting plate and the mounting plate, and combined with the push processing of the push spring, the sealing gasket can fully fit the outside of the cable, and then the outside of cables with different diameters can be fit-sealed, avoiding the different cable diameters affecting the sealing and protection quality of the cable and the cabinet.

[0010] As an optional solution of the technical solution of the present application, a rain shield frame is fixedly installed on the top surface of the cabinet.

[0011] By adopting the above technical solution, the cabinet body is protected from rain by the structural function of the rain shield frame.

[0012] As an optional solution of the technical solution of the present application, each guide tube is provided with a guide groove on the inner side, and the number of the guide grooves is four groups, and each extrusion plate is fixedly installed with a guide block on the outer surface, and the guide block is slidably installed inside the guide groove.

[0013] By adopting the above technical solution, the vertical movement stability of the extrusion plate is ensured by the guiding sliding action of the guide groove on the guide block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The technical solution of the present application is a cable sealing device for a distribution cabinet, which transmits and connects a sealing gasket and an extrusion plate that can be inside a guide tube through a connecting plate and a mounting plate, and combines the pushing and pushing treatment of a push spring, so that the sealing gasket can be pushed and pushed by the outside of the cable. The distance between the sides of the two groups of sealing gaskets can be adjusted, so that the sealing gasket can fully fit the outside of the cable, and then the outside of cables with different diameters can be fitted and sealed to avoid the difference in cable diameters affecting the sealing and protection quality of the cable and the cabinet.

[0016] 2. The technical solution of the present application is a cable sealing device for a distribution cabinet. Through the guiding sliding action of the guide groove on the guide block, when the sealing gasket is resisted by the outside of the cable, the extrusion plate can only move vertically inside the guide tube to squeeze the push spring and cause it to deform, thereby ensuring the rationality of the position adjustment of the sealing gasket.

[0021] like Figure 1-3 As shown, the utility model provides a technical solution: a cable sealing device for a distribution cabinet, a cabinet body 11 is fixedly installed on the top surface of a mounting base 1, a wire threading groove 2 is opened inside the side of the cabinet body 11, and the number of the wire threading grooves 2 is several groups, and a rain shield frame 12 is fixedly installed on the top surface of the cabinet body 11.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), guide tubes 21 are vertically fixedly installed on the surfaces of both ends of the side of the cabinet 11, and the guide tubes 21 are located on both sides of the outside of the wire threading groove 2, and an extrusion plate 22 is slidably installed on the inner bottom surface of each guide tube 21, and connecting rods 23 are fixedly installed on the outer end surfaces of each extrusion plate 22, and a connecting plate 24 is fixedly installed between the top ends of the sides of each two groups of connecting rods 23, and a sealing gasket 26 is detachably bonded to the bottom surface of each connecting plate 24.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each guide tube 21 has a guide groove 3 on its inner side, and the number of the guide grooves 3 is four. A guide block 31 is fixedly mounted on the outer surface of each extrusion plate 22, and the guide block 31 is slidably mounted inside the guide groove 3.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown in the figure, each guide tube 21 has a push spring 27 movably sleeved inside, and the bottom surface of the push spring 27 movably fits the outer surface of the extrusion plate 22.

[0025] During operation, after the required cables are passed through the wire threading trough 2 from the inside of the cabinet 11, the side of the sealing gasket 26 is squeezed and pushed after the cables are passed through, so that the sealing gasket 26 can drive the squeezing plate 22 to move vertically inside the guide tube 21 synchronously, and then the two groups of sealing gaskets 26 can move vertically relative to each other inside the wire threading trough 2, and the distance between the sealing gaskets 26 is adjusted so that they can fully fit against the outside of the cable, and the outside of the cable is sealed. In the process of vertical movement of the squeezing plate 22, the push spring 27 can be squeezed and deformed. After the cable is pulled out of the wire threading trough 2, the recovery of the push spring 27 can provide the sealing gasket 26 with a corresponding vertical driving force to restore its position, thereby facilitating subsequent readjustment and use.
