[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figures 1 to 3 As shown, the cable installation assembly of the present invention includes a connector 1, a sealing piece 3 and a sealing member. A cavity is formed inside the connector 1. The inlet end of the connector 1 is provided with an inlet hole. The cable 5 is inserted into the connector 1 from the inlet hole. The outlet end of the connector 1 is open. The sealing piece 3 is in active deformation contact with the opening of the outlet end of the connector 1. An adjusting member and a bending member are provided inside the connector 1. The bending member bends the cable 5 to a certain extent inside the connector 1 so that when the cable 5 is subjected to external tension, it is not easily affected by the tension and separated from the relatively connected equipment or pipeline. The sealing member and the sealing piece 3 are respectively sealed at the inlet end and the outlet end of the connector 1 to reduce the possibility of external impurities or water entering the connector 1 and improve the overall sealing effect of the installation assembly.

[0027] The bending part includes two wire portions 23 and two connecting portions 24. The two end portions of any wire portion 23 are rotatably connected to the two ends of the length of the two connecting portions 24 at the same time. The two wire portions 23 are respectively located at the two ends of the length of the same connecting portion 24. The middle parts of the two connecting portions 24 are rotatably connected to the connector 1. The cable 5 passes around the two wire portions 23 at the same time. The adjusting component is used to adjust the rotation angle of the bending part relative to the connector 1. When the bending part rotates, the cable 5 is bent inside the connector 1.

[0028] The adjusting component includes an adjusting rod 2 and two adjusting pieces 21. The adjusting rod 2 is rotatably matched with the joint 1. The two adjusting pieces 21 slide relatively synchronously along the adjusting rod 2. The two end portions of the length of the bending piece are slidably matched with the two adjusting pieces 21 respectively. The two end portions of the length of the adjusting rod 2 are provided with threads with opposite thread directions. The two adjusting pieces 21 are respectively threadedly matched with the two end portions of the adjusting rod 2. The adjusting piece 21 fits with the inner wall of the joint 1. One end of the adjusting rod 2 extends to the outside of the joint 1 and an adjusting portion is provided at the line inlet end of the joint 1. The adjusting rod 2 is driven to rotate by rotating the adjusting portion, and the two adjusting pieces 21 are further made relatively close to or far away from each other along the length direction of the adjusting rod 2.

[0029] Both ends of the length of the connecting part 24 are rotatably connected with connecting blocks 241, and the two adjusting members 21 are provided with sliding grooves 211. The connecting blocks 241 slide with the adjusting members 21 in a direction perpendicular to the length of the adjusting rod 2, and the two adjusting members 21 are also provided with strip grooves for the cable 5 to pass through. When the adjusting rod 2 rotates to drive the two adjusting members 21 closer, the two adjusting members 21 push the bending member to rotate and increase the bending degree of the cable 5 passing through the wire portion 23, thereby improving the fixing strength of the cable 5.

[0030] In order to further improve the stability of the adjustment member 21 moving in the joint 1, the adjustment component also includes a guide rod 22, which is arranged inside the joint 1 parallel to the adjustment rod 2, and the adjustment rod 2 and the guide rod 22 are respectively connected to the two ends of the length of the adjustment member 21, and the adjustment member 21 is slidably sleeved on the guide rod 22.

[0031] The sealing piece 3 can be made of elastic material so that it can be deformed when it is squeezed. The material of the sealing piece 3 can be rubber, and the material of the connector 1 can also be rubber, or a rubber layer is provided on its inner side to enhance the sealing connection strength between the sealing piece 3 and the terminal of the connector 1. The width of the sealing piece 3 decreases along the direction approaching the connector 1. A connecting rod 212 is fixed on the adjusting piece 21 near the outlet end of the connector 1. The connecting rod 212 is fixed to the sealing piece 3. To ensure the connection strength, the connecting rod 212 and the sealing piece 3 are preferably connected by two or four connecting rods 212. The sealing piece 3 is provided with an outlet hole for the cable 5 to pass through, and is also provided with a through hole for avoiding the adjusting rod 2 and the guide rod 22.

[0032] When the two adjusting parts 21 are relatively close to each other, the blocking part 3 gradually approaches the connector 1 under the pulling force of the adjusting part 21 and the connecting rod 212, and gradually extends into the outlet end of the connector 1. Because the blocking part 3 is made of elastic material, when the blocking part 3 contacts the connector 1 from the outlet end of the connector 1, the blocking part 3 and the connector 1 are squeezed against each other, and the blocking part 3 is deformed by the squeezing, thereby improving the sealing connection effect between the blocking part 3 and the connector 1. At the same time, when the blocking part 3 is squeezed, the cable 5 is also squeezed through the outlet hole, thereby further improving the connection strength between the blocking part 3 and the cable 5, and reducing the possibility of the cable 5 loosening or falling off when subjected to tension.

[0033] The blocking component includes a blocking block 4 and a connecting piece 41. The blocking block 4 and the connecting piece 41 are both sleeved on the outside of the cable 5. The blocking block 4 can also be made of rubber. The outer diameter of the blocking block 4 decreases in the direction close to the incoming end of the connector 1. The connecting piece 41 is threadedly matched with the incoming hole. When the cable 5 is bent inside the connector 1, the blocking block 4 moves with the cable 5 to the position of the connector 1 until the blocking block 4 is inserted into the incoming hole to fully block the incoming hole. Then, the connecting piece 41 is rotated to make the connecting piece 41 threadedly connected to the incoming hole to improve the sealing connection strength between the cable 5 and the incoming end of the connector 1.

[0034] In addition, in order to facilitate the fixation of the connector 1 to the relevant equipment or pipeline, a fastener 11 is also provided on the outside of the connector 1. The fastener 11 is used for threaded connection with the equipment or pipeline. By rotating the fastener 11, the connector 1 can be quickly fixed and removed from the relevant equipment or pipeline.

[0035] The cable installation assembly provided by the present invention improves the fixing strength of the cable when it enters and exits a device or a pipeline, reduces the possibility of the cable falling off when pulled or subjected to external forces, and at the same time ensures the sealing connection strength with the cable.
