[0016] Figure 1-4 This illustration shows a protective sleeve connection structure to a wall according to an embodiment of the present invention. It includes a through-wall sleeve 2 integrally cast with the cable well wall 1; a cable protective sleeve 3 is slidably connected to the inner cavity of the through-wall sleeve 2; an outer bushing 4 is welded to the surface of the cable protective sleeve 3; four embedded screws 5 are pre-embedded in the inner cavity of the cable well wall 1; an open collar 6 is fitted onto the surface of the four embedded screws 5; nuts 7 are threadedly fixed to the surface of each of the four embedded screws 5; and plugging rings 8 are welded to the surfaces of the left and right ends of the cable protective sleeve 3. The plugging ring 8 and the opening sleeve 6 are welded and fixed. The inner cavity of the through-wall sleeve 2 is filled with silicate cement 11. The silicate cement 11 is filled on the surface of the cable protection sleeve 3. Rubber sleeves 12 are fitted on both the left and right ends of the cable protection sleeve 3. The rubber sleeves 12 are located between the inner cavities of the plugging ring 8 and the opening sleeve 6. By setting the rubber sleeves 12, the inner cavities of the cable protection sleeve 3 and the left and right ends of the through-wall sleeve 2 can be sealed and protected, which can further reduce the occurrence of rainwater entering the inner cavity of the through-wall sleeve 2.

[0017] Working principle: When using this utility model, the user pre-embeds the pre-embedded screw 5 into the inner cavity of the cable well wall 1, ensuring that the pre-embedded screw 5 is positioned so that the opening collar 6 can be properly fitted.
