Description

Technical Field

[0001] This utility model relates to the field of sleeve technology, and in particular to a leak-stopping structure for a through-wall sleeve. Background Technology

[0002] Through-wall sleeves play an important role in protecting pipes from damage, installing and maintaining pipes, preventing cross-contamination, and preventing water from flowing to lower floors. They are now widely used.

[0003] During construction, holes are typically pre-drilled in the wall, and then the gaps are filled with flexible materials such as plaster for temporary sealing. However, the sealing effect of this method cannot be guaranteed. If water enters the hole during construction, it poses a significant risk of moisture damage to the wall. In the later stages of use, the hole may detach and crack, making it unusable for long periods and increasing maintenance costs. The duration of waterproofing and sealing cannot be guaranteed. Therefore, this application proposes a through-wall sleeve sealing structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wall sleeve sealing structure, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a wall sleeve sealing structure, including a first rectangular plate with a circular opening in the middle. A sealing tube is fixedly connected to one side of the first rectangular plate near the circular opening. A first threaded groove and a second threaded groove are respectively provided at both ends of the sealing tube. A pressure plate is provided on one side of each of the first and second threaded grooves. A first threaded cylinder and a second threaded cylinder are fixedly connected to the two pressure plates near the first and second threaded grooves, respectively. The first threaded cylinder is threaded to the first threaded groove, and the second threaded cylinder is threaded to the second threaded groove. A second rectangular plate is provided at the end of the sealing tube away from the first rectangular plate.

[0006] Preferably, in any of the above schemes, the length of the second threaded groove is greater than the length of the first threaded groove.

[0007] The technical effect achieved by adopting the above solution is that, by using this solution, after the sealing tube is inserted into the pre-reserved hole in the wall, if the length of the sealing tube is less than the thickness of the wall, the second threaded cylinder can extend into the second threaded groove to a greater extent, which can be applied to walls of different thicknesses and is more reliable.

[0008] Preferably, in any of the above solutions, mounting holes are fixedly connected to the four corners of the first rectangular plate.

[0009] The technical effect achieved by adopting the above solution is that the first rectangular plate can be installed on the wall by using this solution. After the first rectangular plate is fixed, the sealing pipe is fixed accordingly, which increases the stability during the subsequent installation of the first threaded cylinder and the second threaded cylinder.

[0010] Preferably, in any of the above solutions, a first waterproof layer and a first moisture-proof layer are provided on the side of the first rectangular plate and the second rectangular plate away from the pressure plate, wherein the first waterproof layer is made of polyurethane coating and the first moisture-proof layer is made of carbon steel.

[0011] The technical effect achieved by adopting the above solution is as follows: by using this solution, a high-performance liquid waterproof material formed by the chemical reaction of polyurethane coating can be used. It has good waterproof properties. Combined with its softness, it can better adhere to the wall surface, increasing the sealing between the wall surface and the first rectangular plate and the second rectangular plate. At the same time, combined with the waterproof and hard carbon steel material, it can play a certain plasticity role, better compressing the first waterproof layer to adhere to the wall surface without deformation.

[0012] Preferably, the outer wall of the sealing tube is provided with a second waterproof layer and a second moisture-proof layer, wherein the second waterproof layer is made of EPDM rubber and the second moisture-proof layer is made of polyvinyl chloride.

[0013] The technical effects achieved by adopting the above solution are as follows: This solution utilizes the waterproof and plastic properties of EPDM rubber, making it a more reliable outer wall for sealing tubes. Because its molecular chain does not contain hydrophilic groups (such as hydroxyl or carboxyl groups) and its molecular arrangement is relatively dense, it absorbs almost no water. Even in a humid environment for a long time, its water absorption rate is extremely low (usually far below 0.05%), and it will not swell, deform, or deteriorate due to water absorption. This effectively increases the moisture resistance of the sealing tube and better protects the items inside.

[0014] Preferably, in any of the above schemes, the length of the first threaded groove is greater than the length of the first threaded cylinder, and the length of the second threaded groove is greater than the length of the second threaded cylinder.

[0015] The technical effect achieved by the above solution is that, by using this solution, after the first and second threaded cylinders rotate and extend into the first and second threaded grooves, the pressure plate squeezes the first and second rectangular plates, making the first and second rectangular plates fit the wall surface better and increasing the sealing between the first and second rectangular plates and the wall surface.

[0016] This utility model has the following advantages:

[0017] 1. This through-wall sleeve sealing structure involves inserting a sealing pipe into a pre-reserved hole in the wall, allowing a first rectangular plate to adhere to the wall surface. The first rectangular plate is then fixed in place using four mounting holes. A first threaded cylinder is threaded into the first threaded groove until the pressure plate adheres to and presses the first rectangular plate firmly against the wall, achieving a seal. A second rectangular plate is then placed on the other side of the pre-reserved hole, and simultaneously, a second threaded cylinder is threaded into the second threaded groove until the pressure plate adheres to and presses the second rectangular plate firmly against the wall, thus completing the sealing work on both sides of the pre-reserved hole and ensuring waterproofing.

[0018] 2. This through-wall sleeve sealing structure, with a first waterproof layer and a first moisture-proof layer, further increases the sealing between the wall and the first rectangular plate and the second rectangular plate, so that the first rectangular plate and the second rectangular plate are completely attached to the wall. At the same time, the second waterproof layer and the second moisture-proof layer can increase the moisture resistance and strength of the sealed pipe, and better protect the items inside the sealed pipe.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0027] like Figures 1 to 5As shown, a wall sleeve sealing structure includes a first rectangular plate 1 with a circular opening in the middle. A sealing tube 3 is fixedly connected to one side of the first rectangular plate 1 near the circular opening. A first threaded groove 10 and a second threaded groove 11 are respectively opened at both ends of the sealing tube 3. A pressure plate 4 is provided on one side of the first threaded groove 10 and the second threaded groove 11. A first threaded cylinder 12 and a second threaded cylinder 13 are fixedly connected to the two pressure plates 4 near the first threaded groove 10 and the second threaded groove 11, respectively. The first threaded cylinder 13 is threadedly connected to the first threaded groove 10, and the second threaded cylinder 13 is threadedly connected to the second threaded groove 11. A second rectangular plate 5 is provided at the end of the sealing tube 3 away from the first rectangular plate 1.

[0028] As an optional technical solution of this utility model, the length of the second threaded groove 11 is greater than the length of the first threaded groove 10. By using this solution, the sealing tube 3 can be inserted into the pre-reserved hole in the wall. If the length of the sealing tube 3 is less than the thickness of the wall, the second threaded cylinder can have a larger range of insertion into the second threaded groove 11. This can be applied to walls of different thicknesses and is more reliable.

[0029] As an optional technical solution of this utility model, mounting holes 2 are fixedly connected to the four corners of the first rectangular plate 1. By using this solution, the first rectangular plate 1 can be installed on the wall. After the first rectangular plate 1 is fixed, the sealing tube 3 is fixed accordingly, which increases the stability during the subsequent installation of the first threaded cylinder 12 and the second threaded cylinder 13.

[0030] As an optional technical solution of this utility model, a first waterproof layer 6 and a first moisture-proof layer 7 are provided on the side of the first rectangular plate 1 and the second rectangular plate 5 away from the pressure plate 4. The first waterproof layer 6 is made of polyurethane coating, and the first moisture-proof layer 7 is made of carbon steel. By using this solution, the high-performance liquid waterproof material formed by the chemical reaction of polyurethane coating can be utilized, which has good waterproof performance. Combined with its soft characteristics, it can better adhere to the wall surface, increasing the sealing between the wall surface and the first rectangular plate 1 and the second rectangular plate 5. At the same time, the carbon steel material, which has good waterproof effect and is hard, can play a certain plastic role, better compressing the first waterproof layer 6 to adhere to the wall surface without deformation.

[0031] As an optional technical solution of this utility model, the outer wall of the sealing tube 3 is provided with a second waterproof layer 8 and a second moisture-proof layer 9. The second waterproof layer 8 is made of EPDM rubber, and the second moisture-proof layer 9 is made of polyvinyl chloride. By using this solution, the waterproof and plastic characteristics of EPDM rubber can be utilized to make the outer wall of the sealing tube 3 more reliable. Utilizing the fact that its molecular chain does not contain hydrophilic groups (such as hydroxyl, carboxyl, etc.) and its molecular arrangement is relatively dense, it itself hardly absorbs water. Even when in a humid environment for a long time, its water absorption rate is extremely low (usually far below 0.5%), and it will not swell, deform, or deteriorate in performance due to water absorption. This effectively increases the moisture resistance of the sealing tube 3 and better protects the items inside the sealing tube 3.

[0032] As an optional technical solution of this utility model, the length of the first threaded groove 10 is greater than the length of the first threaded cylinder 12, and the length of the second threaded groove 11 is greater than the length of the second threaded cylinder 13. By using this solution, when the first threaded cylinder 12 and the second threaded cylinder 13 rotate and extend into the first threaded groove 10 and the second threaded groove 11, the pressure plate 4 squeezes the first rectangular plate 1 and the second rectangular plate 5, making the first rectangular plate 1 and the second rectangular plate 5 fit the wall surface better and increasing the sealing between the first rectangular plate 1 and the second rectangular plate 5 and the wall surface.

[0033] This type of through-wall sleeve leak-sealing structure requires the following steps when used:

[0034] 1) Insert the sealing tube 3 into the pre-reserved hole in the wall so that the first rectangular plate 1 fits against the wall surface, and use the four mounting holes 2 to install and fix the first rectangular plate 1.

[0035] 2) Thread the first threaded cylinder 12 to the first threaded groove 10 until the pressure plate 4 fits and presses the first rectangular plate 1 tightly;

[0036] 3) Place the second rectangular plate 5 on the other side of the reserved hole;

[0037] 4) Thread the second threaded cylinder 13 to the second threaded groove 11 until the pressure plate 4 fits and presses the second rectangular plate 5.

[0038] In summary, when using the device, the user inserts the sealing tube 3 into the pre-drilled hole in the wall, allowing the first rectangular plate 1 to adhere to the wall surface. The first rectangular plate 1 is then fixed in place using the four mounting holes 2. The first threaded cylinder 12 is threaded into the first threaded groove 10 until the pressure plate 4 adheres to and presses the first rectangular plate 1 firmly, ensuring a stable seal between the first rectangular plate 1 and the wall surface. The second rectangular plate 5 is then placed on the other side of the pre-drilled hole, and simultaneously the second threaded cylinder 13 is threaded into the second threaded groove 11 until the pressure plate 4 adheres to and presses the second rectangular plate 5 firmly, ensuring a stable seal between the second rectangular plate 5 and the wall surface. This completes the sealing of both sides of the pre-drilled hole, ensuring a waterproof effect. Finally, the first waterproof layer 6 and the first moisture-proof layer 7 further enhance the seal between the wall surface and the first rectangular plate 1 and the second rectangular plate 5, ensuring complete adhesion between the first rectangular plate 1 and the second rectangular plate 5. Simultaneously, the second waterproof layer 8 and the second moisture-proof layer 9 increase the moisture resistance and strength of the sealing tube 3, better protecting the contents inside.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
