Description

Technical Field

[0001] This utility model relates to the field of water supply pipe installation, and in particular to a protective structure for water supply pipe assembly through-wall installation. Background Technology

[0002] During operation, the water inside a water supply pipe generates pressure. When a water pipe passes through a wall, without protective measures, the pressure will act directly on the wall. Protective devices, such as wall sleeves, can evenly distribute the pressure of the water pipe onto the sleeve and the surrounding wall structure, preventing localized cracks or damage to the wall due to excessive pressure.

[0003] Chinese patent announcement number CN221743386U discloses a protective structure for water supply pipe assembly through-wall installation, including a rubber ring and an axial spring assembly. The rubber ring is fixedly sleeved on the water supply pipe and fixed to the wall. Two sets of axial spring assemblies are used, installed on both sides of the wall and connected to the water supply pipe. The rubber ring with radial elastic buffering structure and the two sets of axial spring assemblies with axial elastic buffering can achieve buffering and shock absorption in the event of large vibrations of the water supply pipe, thus preventing damage to the wall.

[0004] However, this device has the following drawbacks in use: While it can provide protection for the water supply pipe using a rubber ring and axial spring assembly, installing the rubber ring requires drilling a hole in the wall to fit it. Therefore, precise hole positioning is necessary, and if the hole is too large, the rubber ring will not fit well against the wall during installation. To address these drawbacks, we propose a through-wall protection structure for water supply pipe assemblies. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective structure for water supply pipe assembly installation through walls.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a protective structure for water supply pipe assembly through-wall installation, comprising:

[0007] The sheath includes an outer tube, a grouting assembly disposed on the surface of the outer tube, and a leak-proof assembly disposed on the surface of the outer tube.

[0008] A water supply pipe fixing structure is provided at both ends of the outer pipe for fixing the water supply pipe.

[0009] The grouting assembly includes a baffle fixedly installed on the outer surface of the outer pipe, a grouting pipe fixedly installed on the right side of the baffle, and multiple leakage holes equidistantly opened on the surface of the grouting pipe.

[0010] Preferably, the leak-proof assembly includes a leak-proof retaining ring, two through holes formed on the surface of the leak-proof retaining ring, and a sealing part provided on the surface of the outer tube.

[0011] Preferably, the through hole allows the grouting pipe to pass through, and a sealing plug is inserted into the inner wall of the grouting pipe.

[0012] Preferably, the sealing component includes a first sealing ring fixedly installed on the surface of the grouting pipe, and a second sealing ring fixedly installed on the surface of the outer pipe.

[0013] Preferably, the water supply pipe fixing structure includes a conical rubber sleeve fitted on the inner wall of the outer pipe, and a locking cap threaded onto the surface of the outer pipe.

[0014] Preferably, the inner wall of the outer tube is provided with a conical groove that is adapted to the conical rubber jacket.

[0015] Preferably, both the locking cap and the conical rubber sleeve have through holes at their centers that are compatible with the water supply pipe.

[0016] Preferably, the outer diameter of the first sealing ring is larger than the inner diameter of the through hole, and the outer diameter of the second sealing ring is larger than the inner diameter of the leak-proof retaining ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a protective sleeve, firstly, a hole is drilled in the wall for the outer pipe to pass through. Then, the outer pipe is placed into the hole, with the baffle on one side of the wall. Next, the leak-proof ring is placed on the other side of the wall. Then, the water supply pipe is fixed inside the outer pipe using the water supply pipe fixing structure. After that, foaming agent is injected into the grouting pipe, which fills the gap between the hole and the outer pipe. The cooperation of the baffle and the leak-proof ring prevents the foaming agent from leaking to the wall. The solidified foaming agent forms a soft connection between the outer pipe and the wall, effectively protecting the water supply pipe. Compared with existing technologies, this device uses the grouting component to fill the gap between the hole and the outer pipe with foaming agent, and the leak-proof component prevents the foaming agent from leaking. On the one hand, because there is a gap between the wall and the outer pipe, the position of the outer pipe can be finely adjusted without precisely drilling a hole in the wall. On the other hand, the foaming agent fills the gap between the hole and the outer pipe, thereby improving the fit between the wall and the outer pipe.

[0019] 2. By setting up a water supply pipe fixing structure, a conical rubber sleeve is placed inside the outer pipe, and then the water supply pipe is passed through the outer pipe. Then, the locking cap is tightened, which can drive the conical rubber sleeve to contract and clamp the water supply pipe inside the outer pipe, thus facilitating the fixing of the water supply pipe. In addition, the conical rubber sleeve can further absorb the amplitude of the water supply pipe. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a protective structure for water supply pipe assembly through-wall installation, including: a protective sleeve and a water supply pipe fixing structure.

[0028] See Figure 1 The sheath includes an outer tube 10, a grouting assembly disposed on the surface of the outer tube 10, and a leak-proof assembly disposed on the surface of the outer tube 10.

[0029] See Figure 2-3 The grouting assembly includes a baffle 20 fixedly installed on the outer surface of the outer pipe 10, a grouting pipe 21 fixedly installed on the right side of the baffle 20, and a plurality of leakage holes 22 equidistantly opened on the surface of the grouting pipe 21.

[0030] First, a hole is drilled in the wall for the outer pipe 10 to pass through. Then, the outer pipe 10 is placed into the hole. At this time, the baffle 20 is on one side of the wall. Then, foaming agent is injected into the grouting pipe 21. The foaming agent can fill the gap between the hole and the outer pipe 10. The solidified foaming agent can form a soft connection between the outer pipe 10 and the wall, effectively protecting the water supply pipe.

[0031] See Figure 1 and Figure 3The water supply pipe fixing structure is set at both ends of the outer pipe 10 to fix the water supply pipe. The water supply pipe fixing structure includes a conical rubber sleeve 50 sleeved on the inner wall of the outer pipe 10 and a locking cap 51 threaded to the surface of the outer pipe 10. The inner wall of the outer pipe 10 is provided with a conical groove 52 that matches the conical rubber sleeve 50.

[0032] Both the locking cap 51 and the conical rubber sleeve 50 have through holes at their centers that are compatible with the water supply pipe. The conical rubber sleeve 50 is placed inside the outer pipe 10, and then the water supply pipe is passed through the locking cap 51, the conical rubber sleeve 50 and the outer pipe 10 respectively. Then the locking cap 51 is tightened, which causes the conical rubber sleeve 50 to contract and clamp the water supply pipe inside the outer pipe 10, thereby facilitating the fixation of the water supply pipe. In addition, the conical rubber sleeve 50 can further absorb the amplitude of the water supply pipe.

[0033] See Figure 2 , Figure 3 and Figure 4 The anti-leakage assembly includes an anti-leakage retaining ring 30, two through holes 31 on the surface of the anti-leakage retaining ring 30, and a sealing component on the surface of the outer pipe 10. The through holes 31 allow the grouting pipe 21 to pass through, and a sealing plug 23 is inserted into the inner wall of the grouting pipe 21.

[0034] See Figure 4 The sealing components include a first sealing ring 40 fixedly installed on the surface of the grouting pipe 21, and a second sealing ring 41 fixedly installed on the surface of the outer pipe 10.

[0035] After the outer pipe 10 is inserted into the hole, the baffle 20 is on one side of the wall. Then, the anti-leakage ring 30 is placed on the other side of the wall and contacts the first sealing ring 40 and the second sealing ring 41 respectively. Then, the water supply pipe is fixed inside the outer pipe 10 using the water supply pipe fixing structure. When the foaming agent is injected into the grouting pipe 21, the cooperation between the baffle 20 and the anti-leakage ring 30 can prevent the foaming agent from leaking to the wall surface. Then, the sealing plug 23 is inserted into the grouting pipe 21 to prevent the foaming agent from flowing out along the grouting pipe 21.

[0036] Compared with existing technologies, this device uses a grouting component to fill the gap between the hole and the outer pipe 10 with foaming agent, and uses a leak-proof component to prevent the foaming agent from leaking. On the one hand, since there is a gap between the wall and the outer pipe 10, the position of the outer pipe 10 can be finely adjusted without the need to precisely drill holes in the wall. On the other hand, the foaming agent can fill the gap between the hole and the outer pipe 10, thereby improving the fit between the wall and the outer pipe 10.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
