Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a cabinet plugging device. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. Existing electrical cabinets often have holes on the side walls of the cabinet so that external cables can extend into the cabinet and connect to electrical equipment. In order to ensure the sealing of the opening, a plugging device is set at the opening.

[0003] Since cables are cylindrical or flat, corresponding occluders need to be made according to the structural characteristics of the cables, resulting in different types of occluders required for cables of different shapes, making the use of existing occluders inconvenient. In addition, in order to adapt to cables of different thicknesses, the sealing layer of the existing occluders is composed of multiple rubber layers. When in use, the excess rubber layer needs to be removed according to the thickness of the cable to ensure that the occluder can be stuck on the surface of the cable, thereby causing material waste. Therefore, a cabinet occluder is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that cables with different shapes and characteristics require different types of occluders, making the use of the existing occluders inconvenient, and proposes a cabinet occluder.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cabinet occluder comprises an annular sealing shell, a surface of which is fixedly connected to a plurality of circumferentially distributed mounting plates, the mounting plates cooperate with bolts to mount the annular sealing shell on a side wall of the cabinet, an air cavity is provided on the inner wall of the annular sealing shell, an elastic band for wrapping cables is provided on the inner side of the annular sealing shell, the elastic band and the inner wall of the annular sealing shell are fixedly connected with an elastic membrane, and the side wall of the annular sealing shell is provided with a relatively arranged anti-detachment support assembly.

[0007] Preferably, the side wall of the annular sealing shell is fixedly connected to an air pumping pipe for helping to inflate the air cavity, and a valve is provided on the air pumping pipe.

[0008] Preferably, the anti-slip support assembly comprises a fixing plate fixedly connected to the side wall of the annular sealing shell, a threaded through hole is provided inside the fixing plate, and an adjusting bolt is threadedly connected inside the threaded through hole.

[0009] Preferably, one end of the adjusting bolt is rotatably connected to a U-shaped frame, the U-shaped frame is slidably connected to the side wall of the annular sealing shell, and the inner wall of the U-shaped frame is rotatably connected to a ratchet.

[0010] Preferably, a groove is provided at the inner top end of the U-shaped frame, and a bevel tooth is slidably connected in the groove, and the bevel tooth is fixedly connected to the inner wall of the groove through a limit spring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model is provided with an annular sealing shell, an elastic membrane and an elastic band. The elasticity of the elastic band itself is utilized to wrap cylindrical cables and flat cables. By using an air pump to pump air into the inner side of the annular sealing shell, the air pressure enables the elastic band to tightly wrap the cable, thereby ensuring that the occluder can adapt to cylindrical cables and flat cables, and can adapt to cables of different thicknesses, thereby avoiding material waste and increasing the scope of use.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4 A cabinet plugging device comprises an annular sealing shell 1, a plurality of circumferentially distributed mounting plates 5 are fixedly connected to the surface of the annular sealing shell 1, the mounting plates 5 cooperate with bolts to mount the annular sealing shell 1 on the side wall of the cabinet, an air cavity is opened on the inner wall of the annular sealing shell 1, an elastic band 3 for wrapping cables is arranged on the inner side of the annular sealing shell 1, an elastic film 2 is fixedly connected between the elastic band 3 and the inner wall of the annular sealing shell 1, an air pumping pipe 6 for helping to inflate the air cavity is fixedly connected to the side wall of the annular sealing shell 1, and a valve is arranged on the air pumping pipe 6;

[0021] It should be noted that the elastic band 3 can be used to wrap cylindrical cables and flat cables by utilizing its own elasticity. By utilizing the air pump 6 to pump air into the inner side of the annular sealing shell 1, the air pressure can be used to tightly wrap the elastic band 3 to ensure that the occluder can adapt to cylindrical cables and flat cables, and can also adapt to cables of different thicknesses, thereby avoiding material waste and increasing the scope of use.

[0022] The side wall of the annular sealing shell 1 is provided with a relatively arranged anti-slip support assembly, and the anti-slip support assembly includes a fixing plate 7 fixedly connected to the side wall of the annular sealing shell 1, a threaded through hole is provided inside the fixing plate 7, an adjusting bolt 8 is threadedly connected in the threaded through hole, one end of the adjusting bolt 8 is rotatably connected to a U-shaped frame 9, the U-shaped frame 9 is slidably connected to the side wall of the annular sealing shell 1, the inner wall of the U-shaped frame 9 is rotatably connected to a ratchet 4, a groove is provided at the inner top end of the U-shaped frame 9, a bevel tooth 10 is slidably connected in the groove, and the bevel tooth 10 is fixedly connected to the inner wall of the groove through a limit spring 11.

[0023] It should be noted that the position of the ratchet 4 is adjusted by adjusting the screw, so that the ratchet 4 can realize the clamping and fixing function of the cable. When the cable is pushed forward, the ratchet 4 will be driven to rotate. When the cable falls under its own gravity, the ratchet 4 will be driven to rotate in the opposite direction (compared to the direction when the cable passes through the opening). Under the limiting effect of the bevel teeth 10, the reverse rotation of the ratchet 4 will be restricted, thereby preventing the cable from falling under its own gravity. There is no need for the staff to manually drag the cable. The staff only needs to push the cable, reducing the burden on the staff's hands.

[0024] When the utility model is used, the annular sealing shell 1 can be installed at the opening of the cabinet side wall by using bolts and the mounting plate 5, and then the elastic band 3 is stretched open, so that the cable passes through the elastic band 3 and then through the opening to extend into the cabinet (in this process, there is no air pressure inside the annular sealing shell 1, and the squeezing force of the elastic band 3 on the cable is very small, which can achieve the function of pushing the cable), and then the U-shaped frame 9 is driven to move by the adjusting bolt 8, and the cable is clamped and fixed by the ratchet 4. Since the elastic band 3 is elastic, the wrapping function of cylindrical cables and flat cables can be achieved, so that the occluder can adapt to cylindrical cables and flat cables, and can also adapt to cables of different thicknesses, thereby avoiding material waste and increasing the scope of use;

[0025] When the cable is pushed forward, the ratchet 4 is driven to rotate. When the cable falls under its own gravity, the ratchet 4 is driven to rotate in the opposite direction (compared to the direction when the cable is pushed forward). Under the limiting effect of the bevel teeth 10, the ratchet 4 is restricted from rotating in the opposite direction, thereby preventing the cable from falling under its own gravity. The staff does not need to manually drag the cable, but only needs to push the cable forward, thereby reducing the burden on the staff's hands.

[0026] When the cable completes its connection function with the electrical equipment inside the cabinet, an external air pump is used to pump air into the annular sealing shell 1 through the air pump pipe 6 to increase the air pressure inside the air cavity so that the elastic band 3 can tightly wrap the cable, thereby realizing the sealing function of the plugger on the cabinet opening.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
