Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Reference Figure 1-Figure 3 The utility model provides a cable tube sealing joint, comprising two cable tubes 1, and also comprising:
[0025] Two connectors 2, one end of the two connectors 2 is fixedly connected to one end of the two cable tubes 1 respectively, and the opposite ends of the two connectors 2 are fixedly connected to docking blocks 3 respectively, and the two docking blocks 3 are arranged in contact;
[0026] The sealing assembly includes a sealing rubber ring 4, a sealing member and a pushing member. The sealing rubber ring 4 is fixedly connected to one of the connectors 2. A connecting tube 5 is sleeved on the other connector 2. The two docking blocks 3 are threadedly connected to the connecting tube 5 after being contacted. The sealing member and the pushing member are respectively arranged on the two docking blocks 3. The connecting tube 5 controls the sealing member through the pushing member to inflate the sealing rubber ring 4. The inflated sealing rubber ring 4 is in sealing contact with the connecting tube 5.
[0027] The docking block 3 connected with the sealing rubber ring 4 is threadedly connected to the connecting pipe 5. After the threaded connection, the connecting pipe 5 seals against the other docking block 3 to achieve a stable connection between the two docking blocks 3.
[0028] To further optimize the solution, a plurality of through grooves 6 are provided at equal intervals along the circumferential direction at one end of the docking block 3 near the sealing rubber ring 4, and the sealing member includes a sliding support ring 7 arranged in the through groove 6, and the outer wall of the sliding support ring 7 is in sliding contact with the inner wall of the through groove 6, the sealing rubber ring 4 is connected to one end of the through groove 6, and the pushing member extends into the through groove 6 and is in contact with the sliding support ring 7.
[0029] During installation, the pusher is inserted into the through groove 6 to push the sliding support ring 7 to move. When the sliding support ring 7 moves, air is pushed into the sealing rubber ring 4, so that the sealing rubber ring 4 is inflated to achieve sealing.
[0030] To further optimize the solution, one end of the other docking block 3 is fixedly connected with a plurality of docking joints 8 at equal intervals along the circumferential direction, and a through hole is opened on the docking joint 8. The pushing member includes a pushing rod 9 slidably connected in the through hole, and one end of the pushing rod 9 extends out of the through hole and is fixedly connected with a pushing head 10. The pushing head 10 extends into the through groove 6 and is in contact with the sliding support ring 7. The other end of the pushing rod 9 passes through the docking block 3 and is in contact with the inner wall of the connecting tube 5.
[0031] Reference Figure 2 The butt joint 8 and the through groove 6 extend into the through groove 6 correspondingly to realize the positioning and docking of the two docking blocks 3. After docking, the pushing head 10 on the pushing rod 9 is located in the through groove 6. As the threaded connection between the connecting pipe 5 and the docking block 3 moves, the pushing rod 9 is driven to move. The pushing rod 9 drives the pushing head 10 to push the sliding support ring 7 to squeeze the air into the sealing rubber ring 4, thereby realizing the inflation and expansion of the sealing rubber ring 4.
[0032] According to a further optimized solution, a circular hole 11 is opened in the middle of the sliding support ring 7 , and a sealing block 12 is fixedly connected to the pushing head 10 , and the sealing block 12 is adapted to the circular hole 11 .
[0033] Reference Figure 1 , Figure 3 When the push head 10 extends into the through groove 6 and contacts and docks with the sliding support ring 7, the sealing block 12 docks and seals with the circular hole 11, thereby sealing the air in the through groove 6 and pushing it into the sealing rubber ring 4. The design of the circular hole 11 facilitates the outside air to enter the through groove 6 before installation, thereby ensuring that there is air in the through groove 6 each time it is installed.
[0034] According to a further optimized solution, a spring 13 is provided in the through groove 6 , and two ends of the spring 13 are fixedly connected to the sliding support ring 7 and the inner wall of the through groove 6 respectively.
[0035] Reference Figure 3 The spring 13 is used to connect the sliding support ring 7. When the connecting pipe 5 is disassembled, the spring 13 can push the sliding support ring 7 to reset. At this time, the gas inside the sealing rubber ring 4 will be extracted, which is convenient for the reinstallation of the connecting pipe 5. When reinstalling, the sealing rubber ring 4 is gradually inflated to achieve sealing.
[0036] According to a further optimized solution, a retaining ring 14 is fixedly connected to the docking block 3 to which the sealing rubber ring 4 is fixedly connected, and the sealing rubber ring 4 is located between the retaining ring 14 and the connecting pipe 5 .
[0037] Reference Figure 1 When the connecting pipe 5 is threadedly connected to the docking block 3, a gap is set between the pipe mouth of the connecting pipe 5 and the retaining ring 14. At the same time, the sealing rubber ring 4 is located in the gap and gradually inflates during the movement of the connecting pipe 5 to achieve filling and sealing of the gap, thereby preventing external water from entering the connecting pipe 5 and the pipe mouth, and avoiding the disadvantage of rust and jamming of the connecting pipe 5 after long-term contact with the docking block and the retaining ring 14.
[0038] According to a further optimized solution, a rubber ring 15 is provided between the sliding support ring 7 and the pushing head 10 , and the rubber ring 15 is fixedly connected to the sliding support ring 7 .
[0039] Reference Figure 3 The rubber ring 15 is provided to achieve sealed docking between the push head 10 and the sliding support ring 7, thereby preventing gas from flowing out and ensuring stable inflation of the sealing rubber ring 4.
