Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a through-wall tube for external walls. Background Art

[0002] Through-the-wall pipes refer to pipes that pass through hot water pipes, air ducts, power lines, etc. in buildings or walls. Through-the-wall pipes are usually used in plumbing projects to bring hot water pipes or cold water pipes from the outdoors into the interior, solving the problem of water inlet and outlet, making life more convenient and faster for residents.

[0003] It has been found in actual use that the existing wall-penetrating pipes have the following deficiencies:

[0004] Due to the high underground water pressure, the thermal expansion and contraction of the pipe and the wall, the temperature difference of the condensate pipe is greater, resulting in excessive pressure deformation of the wall-penetrating pipe and displacement. After long-term use in the wall, the pipe body of the wall-penetrating pipe is bent and deformed, and friction with the wall occurs, causing damage to the pipe and shortening its service life.

[0005] In addition, due to various reasons, such as weathering, aging, damage, etc., when the pipeline leaks and needs to be repaired and replaced, it is necessary to shovel the plug between the wall hole and the through-wall pipe, remove the casing, and then repair the pipeline. This not only saves time and effort, but also causes damage to the building and the casing, which needs to be restored, increasing the replacement cost;

[0006] Therefore, the present application provides a through-wall tube for an exterior wall to meet the demand. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a through-wall tube for an exterior wall.

[0008] The technical problem to be solved by the utility model is to provide a through-wall pipe for an external wall so as to solve the problem of the existing through-wall pipe for an external wall.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A wall tube for an exterior wall comprises: an inner tube, a protective sleeve, a support frame, a telescopic spring, a sealing tube and a sealing cover, wherein the outer end of the inner tube is provided with a protective sleeve, one end of the protective sleeve is provided with a docking port, the other end of the protective sleeve is provided with a receiving port, the interior of the protective sleeve is provided with a support frame, the interior of the support frame is provided with a telescopic spring, the interior of the protective sleeve is provided with a sealing tube, and one end of the sealing tube is provided with a sealing cover.

[0011] Preferably, two groups of the protective sleeves are provided, and the two groups of protective sleeves are nested on the left and right sides of the outer end of the inner tube.

[0012] Preferably, four groups of support frames and telescopic springs are installed inside the protective sleeve, and the four groups of support frames are evenly distributed at the four ends of the inner part of the protective sleeve in a cross shape.

[0013] Preferably, the support frame is arc-shaped and is made of rubber material.

[0014] Preferably, the telescopic spring inside the support frame is vertically arranged, one end of the telescopic spring abuts against the inner wall at the middle of the upper end of the support frame, and one end of the telescopic spring abuts against the inner wall of the protective sleeve.

[0015] Preferably, the support frame and the telescopic spring are close to one end of the receiving interface of the protective sleeve, and a threaded surface is provided on the inner wall of the protective sleeve on one side of the receiving interface.

[0016] Preferably, a thread groove is provided at the outer end of the sealing tube, and the sealing tube passes through the docking port and is connected to the protective sleeve by a thread.

[0017] Preferably, the sealing cover is in an annular shape, and the inner diameter of the through hole in the middle of the sealing cover is larger than the outer diameter of the protective sleeve, and the inner diameter of the through hole in the middle of the sealing cover matches the outer diameter of the inner tube.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] 1. One end of the receiving interface of the protective sleeve is located deep inside the wall. When the inner pipe passes through the protective sleeve, the four sets of support frames inside the protective sleeve can wrap around the outer end of the inner pipe. The arc-shaped support frame is arched in the middle, and the arc-shaped cavity in the middle can provide deformation space. When the inner pipe expands and contracts, the pipe surface contacts the support frame. The inner pipe is buffered by the support frame and the telescopic spring, which can effectively reduce the stress of the inner pipe and compensate for the displacement of the pipe caused by thermal expansion and contraction, avoiding long-term use of buried wall and bending deformation of the through-wall pipe body;

[0020] 2. After the inner tube is installed inside the protective sleeve, the sealing tube and the sealing cover are passed through the inner tube and installed at the opening of the protective sleeve. The sealing tube passes through the docking port and is connected to the protective sleeve by a thread. The sealing tube is embedded in the protective sleeve and wrapped around the outer end of the inner tube, which can improve the protection of the inner tube. The annular sealing cover blocks the opening of the protective sleeve and covers the outer end of the hole in the wall, which can eliminate the connection gap between the protective sleeve and the inner tube, seal the protective sleeve, improve the sealing of the overall pre-buried pipeline, and can also be disassembled without loss, which is convenient for the later inspection and maintenance of the inner tube, which not only saves time and effort, but also reduces damage to the building.

The two groups of protective sleeves 2 can be respectively installed at the openings of the two holes in the wall, which not only facilitates the inner tube 1 to pass through the wall for positioning, but also the protective sleeves 2 can cover the surface of the pipeline, thereby preventing water and other substances from invading the interior of the pipeline.

[0032] In this embodiment, four groups of support frames 3 and telescopic springs 4 are installed inside the protective sleeve 2, and the four groups of support frames 3 are evenly distributed in a cross shape at the four ends of the inner part of the protective sleeve 2. When the inner tube 1 passes through the protective sleeve 2, the four groups of support frames 3 inside the protective sleeve 2 can be wrapped around the outer end of the inner tube 1.

[0033] In this embodiment, the support frame 3 is arc-shaped and is made of rubber material. The middle of the arc-shaped support frame 3 is arched, and the arc-shaped cavity in the middle can provide deformation space. When the inner pipe 1 expands and contracts due to thermal expansion and contraction, the pipe surface contacts the support frame 3. The inner pipe 1 is buffered by the support frame 3 and the telescopic spring 4, which can effectively reduce the stress of the inner pipe 1 and avoid bending and deformation of the wall pipe body caused by long-term use in the wall.

[0034] In this embodiment, the telescopic spring 4 inside the support frame 3 is vertically arranged, one end of the telescopic spring 4 is against the inner wall in the middle of the upper end of the support frame 3, and one end of the telescopic spring 4 is against the inner wall of the protective sleeve 2.
