Referring to fig. 1 to 7, a cable tube sealing structure with strong waterproof performance comprises a tube body 1 spliced end to end, at least two tube bodies 1, and a sealing connection assembly 2 for connecting the two tube bodies 1 spliced together; the specific structure of the tube body 1 is not limited, and may be a corrugated tube, or other tube bodies 1 for protecting cables;

the sealing connection assembly 2 comprises a joint 21 arranged at the end part of the pipe body 1 and a connection cylinder 22 covered outside the joint 21, wherein locking nuts 23 are arranged at two ends of the connection cylinder 22, and the locking nuts 23 are abutted against one end of the joint 21;

a sealing ring 24 is arranged between two adjacent connectors 21; the sealing ring 24 may be bonded to one of the joints 21 to facilitate installation of the sealing ring 24;

the joint 21 comprises a ring portion 211 in contact with the connecting cylinder 22 and a cylinder portion 212 extending into the pipe body 1, the cylinder portion 212 is in a truncated cone shape, the cylinder portion 212 is provided with external threads, the pipe body 1 is provided with internal threads matched with the cylinder portion 212, and the cylinder portion 212 is provided with a water collecting groove 213.

In the process of splicing the two pipe bodies 1, the locking nut 23 is sleeved on the pipe body 1, then the joint 21 is installed on the pipe body 1, the two pipe bodies 1 spliced together are aligned, the sealing ring 24 is positioned between the two joints 21 spliced together, and the parallel connection cylinder 22 is sleeved outside the two joints 21.

In the splicing process, one of the locking nuts 23 is matched with the connecting cylinder 22, the other locking nut 23 is matched with the connecting cylinder 22, and the two connectors 21 can be spliced together by screwing the two locking nuts 23.

In the practical application process, even if liquid permeates between the pipe body 1 and the cylinder body through the contact part of the end face of the pipe body 1 and the joint 21, the liquid can be converged in the water collecting tank 213 due to the fact that the cylinder body is provided with the water collecting tank 213, and the cable is not easy to permeate into the pipe body 1.

The tube 212 is provided with external threads, the tube 1 is provided with internal threads, the tube 212 is in a truncated cone shape, and the conical threads have good sealing performance, so that liquid is not easy to enter the tube 1 to damage a cable.

Referring to fig. 1 to 7, in some embodiments, the pipe body 1 is provided with a water guiding groove 11, the water guiding groove 11 is in a ring shape, the water guiding groove 11 is communicated with the water collecting groove 213, and the water guiding groove 11 includes a hydrophobic wall 12, the hydrophobic wall 12 is located in the middle of the water collecting groove 213, and the liquid collected on the hydrophobic wall 12 enters the water collecting groove 213 under the action of self gravity.

The cylindrical portion 212 and the ring portion 211 are integrally formed, and the outer diameter of the cylindrical portion 212 is larger than the outer diameter of the cylinder.

The cross section of the water collecting tank 213 is semicircular, the water drain wall 12 is vertically arranged, and the cross section of the water guiding tank 11 is fan-shaped.

The end face of the pipe body 1 is in surface contact with the end face of the ring part 211, and a sealing ring 24 is arranged between the pipe body 1 and the ring part 211.

Specifically, after the cable tube sealing structure is assembled, the joint 21 and the tube body 1 are connected through the tube threads to form a waterproof part, and the sealing ring 24 between the two joints 21 is used for sealing the gap between the two joints 21 to prevent liquid from penetrating into the tube body 1.

The two joints 21 and a part of the two pipe bodies 1 are both positioned in the connecting cylinder, the connecting cylinder 22 has a waterproof function, namely, external liquid is not easy to enter the contact part of the two pipe bodies 1, but is guided by the connecting cylinder 22 to a position far away from the splicing of the two pipe bodies 1, so that the connecting cylinder 22 has certain waterproof performance.

After the locking nuts 23 are screwed, the two connectors 21 are respectively abutted, the two connectors 21 are extruded in the direction of approaching each other, and the two pipe bodies 1 are spliced through the connectors 21.

In the position where the liquid permeates into the tube portion 212 through the gap between the lock nut 23 and the tube body 1, the water collecting groove 213 is provided in the tube portion 212, and the water guiding groove 11 is provided in the tube body 1, so that the permeated liquid enters the water collecting groove 213, and the liquid in the water collecting groove 213 flows downward under the action of self gravity.

Therefore, even if the liquid penetrates into the position where the tube body 1 is connected with the tube portion 212, the liquid is not easy to enter the tube body 1, so that the cable tube sealing structure has good waterproof property.

Referring to fig. 1 to 7, in some embodiments, the lock nut 23 is provided with a groove 231 recessed into the lock nut 23 in an axial direction of the lock nut 23, and a portion of the coupling cylinder 22 is located in the groove 231.

The lock nut 23 is further provided with a contact body 232 contacting with the outer wall of the pipe body 1, and the contact body 232 is in surface contact with the outer wall of the pipe body 1. The larger the contact area between the contact body 232 and the pipe body 1 is, the less likely the liquid is permeated into the pipe body 1, and the too large contact surface between the contact body 232 and the pipe body 1 may cause the locking nut 23 to be difficult to rotate, so the contact area between the contact body 232 and the pipe body 1 can be reasonably selected according to actual needs. Alternatively, the contact 232 only plays a role of supporting the lock nut 23, and the water collecting tank 213 and the water guiding tank 11 are provided so that the liquid is not likely to enter the pipe body 1, so that the contact 232 and the pipe body 1 may not be sealed, and even if the pipe body 1 and the contact 232 are not sealed, the liquid is not likely to permeate into the pipe body 1.

The contact body 232 and the lock nut 23 are of an integral structure.

A buffer space 25 is formed between the contact body 232 and the ring portion 211.

In some embodiments, the lock nut 23 is provided with a drain hole that communicates with the buffer space 25. The drain hole is not shown in the figure, and in the practical application process, the drain hole located at the upper side may cause liquid to enter the buffer space 25, however, because the water collecting tank 213 and the water guiding tank 11 are arranged, the liquid is not easy to enter the pipe body 1, so that the water-proof property between the barrel 212 and the pipe body 1 is not affected even if the drain hole is arranged, the arrangement of the drain hole can drain the rainwater in the water collecting tank 213, namely, after the rainwater enters the lower side of the pipe body 1, the rainwater can infiltrate into the buffer space 25 through the contact part of the pipe body 1 and the ring 211, and finally is drained by the drain hole.
