[0028] As a kind of implementation in this embodiment, as Figure 3 and Figure 5As shown, the waterproof mechanism 2 includes a sealing component 3 for preventing water from entering the sleeve body 1 and two groups of disassembly and assembly components 4 for disassembling the sealing component 3. Each group of disassembly and assembly components 4 includes a slide groove 41. Each group of slide grooves 41 is opened on the side of the inner wall of the slot 33 away from the sleeve body 1. A spring 42 is installed on the side of each group of slide grooves 41 away from the slot 33. A limiting rod 43 is slidably installed at the opening of each group of slide grooves 41, and the inner end of the limiting rod 43 is connected to the spring 42. A limiting groove 44 is opened at one end of each group of L-shaped plates 37. Each group of limiting rods 43 is inserted into the limiting groove 44, so that the L-shaped plate 37 is inserted into the slot 33 and the limiting rod 43 is squeezed and pushed at the same time, and the limiting rod 43 is pushed into the slide groove 41 to compress the spring 42 until the L-shaped When the plate 37 is inserted into the slot 33, the limit slot 44 corresponds to the limit rod 43, and the limit rod 43 can be pushed into the limit slot 44 by the restorative force of the spring 42, thereby limiting the L-shaped plate 37. In this way, the installation tube 35 and the second sealing gasket 36 can be installed and fixed. The inner end of each set of limit rods 43 is connected to a pull rod 45, and the end of each set of pull rods 45 away from the limit rod 43 passes through the fixed block 32 and is installed with a pull ring 46, so that pulling the pull ring 46 drives the pull rod 45, and the pull rod 45 drives the limit rod 43 to be pulled out of the limit slot 44. In this way, the installation tube 35 can be pulled, and the installation tube 35 drives the L-shaped plate 37 to be pulled out of the slot 33, thereby completing the disassembly of the installation tube 35 and the second sealing gasket 36, which greatly increases the convenience of the device.

[0029] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, the outer surface of the sealing component 3 is provided with a reinforcing component 5 for reinforcing the installation of the sealing component 3, and the reinforcing component 5 includes a limiting sleeve 1 51 and a limiting sleeve 2 52, which are both sleeved on the outer wall of the connecting pipe 31, and the outer walls of the limiting sleeve 1 51 and the limiting sleeve 2 52 are connected with connecting blocks 53 on both sides, and one end of each group of connecting blocks 53 is penetrated by a threaded hole 54, and the interior of each corresponding two groups of threaded holes 54 is threadedly inserted with a bolt 55, and the lower side of the surface of each group of bolts 55 is threadedly sleeved with a nut 56. This structure allows the limiting sleeve 1 51 and the limiting sleeve 2 52 to be sleeved on the outer surface of the connecting pipe 31 so that the corresponding connecting blocks 53 can fit together, so that each bolt 55 can be threadedly inserted into the corresponding two groups of threaded holes 54, and finally the nut 56 is sleeved on the lower side of the bolt 55, so that the connecting pipe 31, sealing gasket 1 34, mounting pipe 35 and sealing gasket 2 36 can be connected. Reinforcement is carried out so that the connecting tube 31, sealing gasket 1 34, mounting tube 35 and sealing gasket 2 36 fit the surface of the wire better, so that the installation is more stable and the sealing is better. The interior of the limiting sleeve 1 51 and the limiting sleeve 2 52 are evenly connected with convex strips 57, which can increase the friction and pressure between the limiting sleeve 1 51 and the limiting sleeve 2 52 and the connecting tube 31, so that the connecting tube 31, sealing gasket 1 34, mounting tube 35 and sealing gasket 2 36 fit the surface of the wire better and are more stable.

[0030] Working principle: If you need to use this device, you only need to pass the wire through the sleeve body 1 and through the connecting tube 31, sealing gasket 1 34, mounting tube 35 and sealing gasket 2 36. After the sleeve is put on, the sleeve body 1 can be heated at high temperature to make the sleeve body 1 shrink rapidly and wrap the wire. The sealing gasket 2 36 will also fit tightly to the surface of the wire, thereby increasing the sealing performance of the end face where the sleeve body 1 and the wire are bonded, better avoiding the possibility of water seeping into the interior of the sleeve body 1, making the protection effect of the wire better and greatly increasing the practicality of the device. Then, the limiting sleeve 1 51 and the limiting sleeve 2 52 are sleeved on the outer surface of the connecting tube 31 so that the corresponding connecting blocks 53 can fit together. In this way, each bolt 55 can be threaded into the corresponding two sets of threaded holes 54. Finally, the nut 56 is sleeved on the lower side of the bolt 55. In this way, the connecting tube 31, sealing gasket 1 34, mounting tube 35 and sealing gasket 2 36 can be tightened. Fixing is performed so that the connecting tube 31, the sealing gasket 1 34, the mounting tube 35 and the sealing gasket 2 36 are more closely fitted to the surface of the wire, thereby making the installation more stable and the sealing better;

[0031] In addition, if you need to protect larger wires, you only need to pull the pull ring 46 to drive the pull rod 45, and the pull rod 45 drives the limit rod 43 to be pulled out of the limit groove 44 and move it to the slide groove 41 to compress the spring 42. In this way, you can pull the mounting tube 35, and the mounting tube 35 drives the L-shaped plate 37 to be pulled out of the slot 33 until the mounting tube 35 drives the sealing gasket 2 36 to be pulled out of the connecting tube 31. In this way, the larger wires can directly pass through the interior of the connecting tube 31 and the sealing gasket 1 34, so that the sealing gasket 1 34 fits tightly against the surface of the wire.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
