Problems solved by technology

[0004] Since the diameter of the cable tube is larger than the diameter of the cable, and the cover used to close the cable and the cable tube, the position of the through hole is located at the axis, which makes the cable pass through the through hole. In the inclined state, the force on the gasket is uneven, and the force on the bottom is obviously greater than that at other positions. If it goes on for a long time, it will lead to deformation and cracking of the gasket, resulting in poor sealing effect

Embodiment 1

[0036] A nozzle closing device for a cable tube, comprising a connecting seat 1 installed in the cable tube, the connecting seat 1 is coaxial with the cable tube, an outer disc 101 is arranged on the left side of the connecting seat 1, and the outer disc 101 and the cable The transition fit or clearance fit between the pipe walls, on the right end surface of the outer disk 101, a plurality of connecting rods 2 are arranged around the outer side of the connecting seat 1, and the connecting rods 2 have external threads. A compression seal assembly 3 is installed between the plurality of connecting rods 2; a plurality of guide grooves 102 are provided on the inner wall of the connection seat 1, and the guide grooves 102 run through the connection seat 1 to the right, and the The left side of the guide groove 102 is closed, and the depth of the guide groove 102 gradually increases toward the right; The inclined surface 401, the end face of the clamping block 4 away from the guide ...

Embodiment 2

[0039] The plane of the clamping block 4 is provided with a card slot 411, and a rubber backing plate 412 is carded through the card slot 411; the above-mentioned structure can realize soft contact with the insulating shell of the cable, and at the same time increase the connection with the cable. frictional resistance at .

Embodiment 3

[0041] A spring 222 is mounted on the connecting rod 2, and the spring 222 acts between the first nut 211 and the slide plate 402; the setting of the spring 222 is to prevent the insulation of the cable after the clamping block moves excessively. damage to the casing.

Abstract

The invention discloses a tube orifice sealing device of acable tube. The device comprises a connecting seat mounted in a cable tube, the connecting seat and the cable tube are coaxial, an outer disc is arranged on the left side of the connecting seat, and the outer disc and the tube wall of the cable tube are in transition fit or clearance fit. A plurality of connecting rods are arranged on the end face of the right side of the outer disc and surround the outer side of the connecting base, the connecting rods are provided with external threads, and compression sealing assemblies are assembled among the connecting rods. A plurality of guide grooves are formed in the inner wall of the connecting seat, the guide grooves penetrate through the connecting seat towards the right side, and the left sides of the guide grooves are closed. According to the device, coaxial fixation of the cable can be achieved, and meanwhile multiple sealing is achieved.

Description

technical field [0001] The invention relates to a pipe mouth sealing device for a cable pipe. Background technique [0002] The cable pipe is used to lay the pipe between two adjacent cable shafts. The cable passes through the cable pipe, and the cable enters the cable shaft to connect with the equipment. Therefore, it is necessary to install a blocker at the mouth of the cable pipe. , The function of the occluder is to seal the gap between the cable tube and the cable to prevent insects and rodents from entering the cable tube to survive and reproduce. Ensure the smoothness of the cable tube and prevent the cable from being damaged by chewing. [0003] The occluder in the prior art mainly adopts a screw-connected cover, and a through hole passing through the cable is opened at the axis of the cover, and a gasket is arranged at the hole wall of the through hole, and the gasket and the cable are passed through. Contact between the outer walls forms a seal. [0004] Since t...
