Specific embodiments
[0023] The following further describes the present utility model in detail with reference to embodiments:
[0024] Such as Figures 1-6As shown in the figure, the utility model provides a waterproof connection structure for a pipe hole in a building main body, which includes a building wall 1. A pipe hole main body 11 is opened on the building wall 1. A gap closing mechanism 2 is arranged on the inner wall of the pipe hole main body 11. An anti-seepage mechanism 3 is arranged in the middle of the gap closing mechanism 2. The gap closing mechanism 2 includes insertion pipe fittings 21. The number of the insertion pipe fittings 21 is set to two. The two insertion pipe fittings 21 are respectively movably inserted into the two ends of the pipe hole main body 11. A hollow ring 24 is fixedly installed on the inner wall of the insertion pipe fitting 21. A connecting pipe 25 is fixedly connected to the side surface of the hollow ring 24. An annular rubber bladder 26 is fixedly connected to the inner wall of the hollow ring 24. A bent pipe 27 is fixedly connected to the side surface of the hollow ring 24. One end of the bent pipe 27 away from the hollow ring 24 is fixedly connected to a one-way pipe 28. One end of the one-way pipe 28 away from the bent pipe 27 is fixedly connected to an internal thread ring 29. After the pipeline is led out from the inner cavity of the insertion pipe fitting 21, the output end of an external air pump is connected to the internal thread ring 29. By controlling the external air pump to work, gas can be transported into the inner cavity of the hollow ring 24 through the internal thread ring 29, the one-way pipe 28 and the bent pipe 27. Through the design of the connecting pipe 25, the inner cavities between adjacent hollow rings 24 on the same insertion pipe fitting 21 are communicated. The gas then enters the inside of the annular rubber bladder 26, prompting the annular rubber bladder 26 to produce an elastic deformation of expansion, fitting on the outer wall of the pipeline, realizing the function of closing the gap between the pipeline and this structure, and avoiding the problem that rainwater easily enters through the gap.
[0025] Furthermore, as Figures 1-4As shown, a hollowed-out plate 281 is fixedly installed on the inner wall of the one-way pipe 28. A sliding rod 282 is slidably connected to the inner wall of the hollowed-out plate 281. A rubber plug block 283 is fixedly installed at the end of the sliding rod 282. A through-hole plate 285 is fixedly installed on the inner wall of the one-way pipe 28. One end of the rubber plug block 283 away from the sliding rod 282 is movably connected to the side surface of the through-hole plate 285. A central portion of the end of the rubber plug block 283 away from the through-hole plate 285 is fixedly connected to an elastic member 284. One end of the elastic member 284 away from the rubber plug block 283 is fixedly connected to the central portion of the side surface of the hollowed-out plate 281. A pressure rod 286 is fixedly installed at the end of the rubber plug block 283. A support block 22 is fixedly connected to the outer wall of the insertion pipe fitting 21. One end of the support block 22 away from the insertion pipe fitting 21 is fixedly connected to a positioning block 23. When gas is conveyed into the inner cavity of the one-way pipe 28 from the internal thread ring 29, the air pressure will push the rubber plug block 283 to move away from the through-hole plate 285, facilitating the filling of gas. At the same time, the elastic member 284 will be compressed. After stopping inflation, through the restoring elastic force of the elastic member 284, the rubber plug block 283 can be driven to fit on the through-hole plate 285 again, realizing the function of automatically closing the inner cavity of the one-way pipe 28, which is convenient for users. If it is necessary to disassemble the pipeline inside the insertion pipe fitting 21, manually push the pressure rod 286 to cause the rubber plug block 283 to move away from the through-hole plate 285, and then the gas inside the one-way pipe 28 can be discharged, enabling the annular rubber bladder 26 to reset. Subsequently, the pipeline can be disassembled. Insert the insertion pipe fitting 21 at the end of the pipe hole main body 11, and then install the insertion pipe fitting 21 on the building wall 1 with bolts from the positioning block 23. Foaming agent can be filled at the connection between the insertion pipe fitting 21 and the building wall 1 to make a sealed connection between the insertion pipe fitting 21 and the building wall 1.
[0026] Furthermore, as Figure 5 、 Figure 6As shown in the figure, the anti-seepage mechanism 3 includes a first receiving ring 31. A first rubber ring 32 is fixedly connected to the side of the first receiving ring 31. One side of the first rubber ring 32 away from the first receiving ring 31 is movably connected to the end of one of the insertion pipe fittings 21. A second receiving ring 36 is fixedly connected to the end of the inner cylinder 34. A third rubber ring 37 is fixedly connected to the side of the second receiving ring 36 away from the inner cylinder 34. One side of the third rubber ring 37 away from the second receiving ring 36 is movably connected to the end of the other insertion pipe fitting 21. A hidden groove 331 is formed in the outer wall of the outer cylinder 33. A positioning bolt 332 is threadedly connected to the inner cavity of the hidden groove 331. The threaded end of the positioning bolt 332 is movably connected to the outer wall of the inner cylinder 34. Loosen the positioning bolt 332, and then the inner cylinder 34 can be slid in the inner cavity of the outer cylinder 33 to adjust the overall length of the anti-seepage mechanism 3 to adapt to pipe holes of different lengths of the pipe hole main body 11, increasing the practicability. Then tighten the positioning bolt 332 to lock the overall length of the anti-seepage mechanism 3. Through the design of the second rubber ring 35, the connection between the outer cylinder 33 and the inner cylinder 34 can be sealed. Through the design of the first rubber ring 32 and the third rubber ring 37, the whole anti-seepage mechanism 3 can be hermetically connected to the two insertion pipe fittings 21 respectively. If the pipeline leaks, the problem that water seeps into the building wall 1 from the pipe hole main body 11 can be avoided, further ensuring the safety of interior decoration materials or furniture.
[0027] Next, the working principle of the waterproof connection structure of the building main body pipe hole will be specifically described.
[0028] As Figures 1-6 shown in the figure, when in use, first, according to the length of the pipe hole main body 11, slide the inner cylinder 34 in the inner cavity of the outer cylinder 33 to adjust the overall length of the anti-seepage mechanism 3. After the adjustment is completed, tighten the positioning bolt 332. Then insert the whole anti-seepage mechanism 3 into the pipe hole main body 11. Then insert the insertion pipe fittings 21 at both ends of the pipe hole main body 11 respectively, and at the same time, make the first rubber ring 32 and the third rubber ring 37 fit tightly with the two insertion pipe fittings 21 respectively. Then install the insertion pipe fittings 21 on the building wall 1 with bolts. Then fill the foaming agent at the connection between the insertion pipe fittings 21 and the building wall 1. Then the pipeline can be led out through the inner cavity of the insertion pipe fittings 21. Then connect the output end of the external air pump to the internal thread ring 29, control the external air pump to work, and the gas will enter the inside of the annular rubber bladder 26, causing the annular rubber bladder 26 to produce an elastic deformation of expansion and fitting on the outer wall of the pipeline, that is, the waterproof connection treatment work is completed.
[0029] It should be noted that in the description of the present disclosure, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense.
