[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] 1. By setting an assembly structure and a waterproof structure, after connecting two cables to be connected to each other, then the male sleeve and the female sleeve are respectively sleeved on the two cables. When the male sleeve and the female sleeve are assembled into one by the assembly structure, at this time, the sealing component can seal the connection surface between the male sleeve and the female sleeve. Then, waterproof sealant is respectively injected into the male sleeve and the female sleeve along the injection pipes. When the waterproof sealant solidifies, the gaps between the male sleeve, the female sleeve and the cable can be filled and a sealing surface is formed, thereby preventing water from entering the male sleeve and the female sleeve and improving the waterproof performance of the device.

Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0029] Please refer to Figures 1-4 , the present invention provides a technical solution: A cable for joint sealing and waterproofing, including: a cable sleeve, an assembly structure, a waterproof structure, and a cable clamping structure.

[0030] The cable sleeve includes a male sleeve 1 and a female sleeve 2. The inner diameters of the male sleeve 1 and the female sleeve 2 need to be larger than the outer diameter of the cable to be protected.

[0031] The assembly structure includes an internal thread cylinder 3 fixedly installed at the right end of the male sleeve 1, an external thread ring 4 fixedly installed on the outer surface of the female sleeve 2, and a sealing component arranged between the male sleeve 1 and the female sleeve 2.

[0032] The sealing component includes a first sealing ring 6 fixedly installed on the outer surface of the internal thread cylinder 3, a second sealing ring 7 fixedly installed on the outer surface of the female sleeve 2, and a sealing ring 8 arranged between the first sealing ring 6 and the second sealing ring 7. The sealing ring 8 is sleeved on the external thread ring 4, and then the external thread ring 4 is screwed into the internal thread cylinder 3. At this time, the first sealing ring 6 and the second sealing ring 7 will approach each other and squeeze the sealing ring 8, so that the connection gap between the male sleeve 1 and the female sleeve 2 can be sealed by the sealing ring 8 to prevent rainwater from entering.

[0033] The waterproof structure includes injection pipes 5 fixedly installed on the surfaces of the male sleeve 1 and the female sleeve 2 respectively, and plugging components arranged inside the male sleeve 1 and the female sleeve 2 respectively, and a plugging cap 15 threadedly connected to the upper end of the injection pipe 5 at the upper end of the injection pipe 5.

[0034] Inject the waterproof sealant along the injection pipes 5 into the male sleeve 1 and the female sleeve 2 respectively. When the waterproof sealant solidifies, the gaps between the male sleeve 1, the female sleeve 2 and the cable can be filled and a sealing surface can be formed, so that water can be prevented from entering the male sleeve 1 and the female sleeve 2, improving the waterproof performance of the device.

[0035] The plugging component includes a circular rubber plugging ring 9, a T-shaped rubber plugging ring 10, and retaining rings 11 fixedly installed on the inner walls of the male sleeve 1 and the female sleeve 2 respectively. The inner diameters of the circular rubber plugging ring 9 and the T-shaped rubber plugging ring 10 are both adapted to the outer diameter of the cable. The outer diameter of the end face of the T-shaped rubber plugging ring 10 is adapted to the inner diameter of the internal thread cylinder 3. The T-shaped rubber plugging ring 10 and the circular rubber plugging ring 9 are both placed inside the male sleeve 1 and the female sleeve 2. When the cable passes through the male sleeve 1 and the female sleeve 2, at this time, the T-shaped rubber plugging ring 10 and the circular rubber plugging ring 9 will be sleeved on the surface of the cable, and the internal thread cylinder 3 will limit the end face of the T-shaped rubber plugging ring 10, and the external thread ring 4 will limit the end face of the T-shaped rubber plugging ring 10. When the external thread ring 4 is screwed into the internal thread cylinder 3, at this time, the end face of the T-shaped rubber plugging ring 10 will be located between the external thread ring 4 and the internal thread cylinder 3, so as to further improve the waterproof performance.

[0036] The cable clamping structures are respectively arranged on the facing surfaces of the male sleeve 1 and the female sleeve 2 for clamping the cable. The cable clamping structure includes conical sleeves 12 respectively and fixedly installed on the facing surfaces of the male sleeve 1 and the female sleeve 2, a conical spring collet 13 arranged on the inner wall of the conical sleeve 12, and a locking nut 14 threadedly connected to the surface of the conical sleeve 12. A through hole for the cable to pass through is provided at the central position of the locking nut 14, and the inner diameter of the conical spring collet 13 is adapted to the outer diameter of the cable.

[0037] After the cable is inserted into the male sleeve 1 and the female sleeve 2, at this time, the conical spring collet 13 will be sleeved on the surface of the cable. Then, tightening the locking nut 14 can drive the conical spring collet 13 to move and contact the inner wall of the conical sleeve 12. At this time, the conical spring collet 13 will push the circular rubber sealing ring 9 to contact the retaining ring 11, so as to limit the circular rubber sealing ring 9. Therefore, when the waterproof sealant is injected into the male sleeve 1 and the female sleeve 2, the waterproof sealant will be between the circular rubber sealing ring 9 and the T-shaped rubber sealing ring 10, and the circular rubber sealing ring 9 and the T-shaped rubber sealing ring 10 will block the waterproof sealant. On the one hand, it can prevent its leakage, and on the other hand, it can make it filled more densely.

[0038] After the conical spring collet 13 moves and contacts the inner wall of the conical sleeve 12, at this time, the conical spring collet 13 can be contracted to clamp the cable, so as to prevent the cable in the cable sleeve from swinging and causing the waterproof sealant to separate from the cable.

[0039] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered by the protection scope of the present invention.
