The support column 3 is evenly distributed with a plurality of retractable clamping blocks 7 with a dot as the axis, the clamping block 7 is provided with an inclined groove 73, an elastic portion 8 is provided between the inclined groove 73 and the gasket 5, and the driving device 6 engages with the clamping block 7. When the driving device 6 is rotated, the clamping block 7 moves toward the center of the support column 3, so that the elastic portion 8 presses down on the gasket 5, so that the sealing device 4 is deformed and retracted;

[0037] It is worth mentioning that the support column 3 is provided with a flange 31, and the flange 31 is provided with a plurality of mounting holes 32. A tightening groove 33 is provided in the support column 3. The flange 31 is used in conjunction with the mounting holes 32. The mounting holes 32 facilitate the fixing or removal of the support column 3 and the inlet hole of the power distribution cabinet 1. The tightening groove 33 is wide at the top and narrow at the bottom, and is used in conjunction with the sealing sleeve 41.

[0038] It is worth mentioning that the sealing device 4 includes a sealing sleeve 41 and a sealing ring 42. The sealing sleeve 41 is provided with a reduced diameter portion 411 and abuts against the reduced diameter groove. The sealing ring 42 is arranged on the inner wall of the sealing sleeve 41. The sealing sleeve 41 can be made of elastic rubber material. The reduced diameter portion 411 is used in conjunction with the tightening groove 33. The sealing ring 42 strengthens the sealing performance of the connection between the sealing sleeve 41 and the cable.

[0039] It is worth mentioning that the gasket 5 abuts against the end surface of the sealing sleeve 41. The gasket 5 is evenly distributed with a plurality of convex humps 51 with the dot as the axis. Guide plates 52 are provided on both sides of the convex humps 51. The guide plates 52 are provided with guide grooves 53. The gasket 5 increases the contact area with the sealing sleeve 41 and collects all the forces of the elastic part 8 and transmits them to the sealing sleeve 41. The convex humps 51 prevent the spring 81 from detaching. The guide plates 52 are used in conjunction with the guide grooves 53. The guide grooves 53 provide an up and down guiding function for the cylinder 82 to prevent the cylinder 82 from deviating from the axis line of the cylinder 82 and the convex humps 51 during the up and down movement of the cylinder 82, thereby ensuring that the force of the spring 81 is concentrated.

[0040] It is worth mentioning that the elastic part 8 includes a spring 81 and a cylinder 82. The cylinder 82 is provided with a blind hole 821 and a chamfered corner 822. The spring 81 is arranged on the outer wall of the convex hull 51 and abuts against the blind hole 821, so that the cylinder 82 abuts against the inclined groove 73. Guide pillars 823 are provided on both sides of the cylinder 82 and are slidably arranged in the guide groove 53. The blind hole 821 prevents the spring 81 from detaching from the cylinder 82, and the chamfered corner 822 reduces the friction with the inclined groove 73. The guide pillars 823 are used in conjunction with the guide groove 53.

[0041] It is worth mentioning that a plurality of equally spaced gear grooves are provided on one side of the clamping block 7, and an abutment surface 72 is provided on the end face of the clamping block 7. The gear groove is used in conjunction with the gear 63, and the abutment surface 72 can be arc-shaped to better fit the surface of the cable;

[0042] It is worth mentioning that the driving device 6 includes a column 61, a driving nut 62, and a gear 63. The column 61 is fixed to the end face of the support column 3 by screws. The bottom of the column 61 is evenly distributed with a number of movable grooves 611 with the dot as the axis. The clamping block 7 is slidably set in the movable groove 611. The outer wall of the column 61 is provided with an annular embedded groove 612. The inner wall of the column 61 is provided with a support shaft 613 and is located on one side of the movable groove 611. The gear 63 is inserted into the support shaft 613 and meshes with the gear tooth groove. The detachable column 61 is convenient for installing the clamping block 7 and its elastic part 8, the gasket 5, and the sealing device 4. The movable groove 611 provides a telescopic guide for the clamping block 7. The annular embedded groove 612 prevents the driving nut 62 from being separated from the column 61 when rotating. The support shaft 613 provides support for the gear 63.

[0043] It is worth mentioning that the inner wall of the driving nut 62 is provided with a barb 621, which abuts against the annular groove 612. The inner wall of the driving nut 62 is evenly distributed with a number of equally spaced gear blocks 622 with the circle as the axis, and meshes with the gear 63. The barb 621 is used in conjunction with the annular groove 612, and the gear block 622 drives the gear 63 to rotate.

[0044] The use principle of the utility model is now described as follows:

[0045] Pass the cable through the sealing sleeve 41, rotate the drive nut 62 counterclockwise, the gear block 622 meshes with the gear 63 to make it rotate counterclockwise, the gear 63 meshes with the gear teeth, so that the clamping block 7 moves toward the center of the support column 3, and the abutting surface 72 gradually approaches the cable until it abuts against the cable surface, and then continue to apply the rotation force until a large resistance is generated and stop rotating the drive nut 62. The above steps complete the fixing of the cable to prevent the cable from being pulled and reduce the sealing performance between the cable and the sealing sleeve 41;

[0046] At the same time, as the clamping block 7 moves, the distance between the inclined groove 73 and the gasket 5 is gradually shortened, and the cylinder 82 moves on the inclined groove 73 and presses down, so that the spring 81 stores energy, and the spring 81 releases elastic force to the sealing sleeve 41 and the clamping block 7, so that the clamping block 7 is fixed in the position after the movement, and the reduced diameter portion 411 follows the tightening groove 33, so that the sealing sleeve 41 is deformed and shrinks inwardly under force, and is tightly attached to the cable surface, thereby improving the sealing of the cable.

[0047] The above design scheme can make the product have the advantages of convenient maintenance, convenient operation and good protection.

[0048] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
