The waterproof sleeve and the pipe will age after long-term use, and water seepage will occur between the sleeve and the pipe after aging. At the same time, there is generally a sealing material between the pipe and the kit, and the sealing material needs to be compressed to have a high sealing performance. When the pipe is connected, the sleeve is pre-buried in the roof structure, which easily makes it difficult for the subsequent waterproof sealing material to fill the gap between the sleeve and the pipe. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: This example aims to provide a roof anti-leakage pipe fitting.

[0024] according to Figures 1 to 4 As shown, including tube body 1,

[0025] The tube body 1 extends in the up-down direction, and an annular step is provided on the inner wall of the tube body 1 .

[0026] A waterproof component 2 is provided in the tube body 1. The waterproof component 2 is a tubular structure extending up and down. The lower end of the waterproof component 2 abuts against the step. The waterproof component 2 can be made of waterproof rubber material.

[0027] A plurality of penetrating strip avoidance openings 102 are provided on the upper part of the side wall of the tube body 1. The strip avoidance openings 102 extend up and down, and the strip avoidance openings 102 are an upper opening structure. A convex plate 201 extending up and down is provided on the side wall of the waterproof component 2. The convex plate 201 is plugged into the interior of the strip avoidance opening 102, and the convex plate 201 passes through the strip avoidance opening 102. The waterproof component 2 is fixedly connected to the drainage component through the convex plate 201.

[0028] The drainage component includes a connecting sleeve 202 and a canopy 203. The connecting sleeve 202 is fixedly sleeved between the lower parts of the outer surfaces of the multiple convex plates 201. The connecting sleeve 202 extends in the up and down directions. The inner wall of the connecting sleeve 202 contacts the outer surface of the pipe body 1. The canopy 203 is fixedly sleeved on the lower end of the outer surface of the connecting sleeve 202. The outer surface of the canopy 203 is a cone with a larger upper part and a smaller lower part.

[0029] A fastener 3 is movably sleeved on the outer surface of the tube body 1, and a plurality of shrinkage seams are provided on the outer surface of the fastener 3. A fastening ring 4 is sleeved on the fastener 3 to tighten the shrinkage seams of the fastener 3. A conical thread connection is provided on the outer surface of the fastener 3, and the conical thread structure is narrow at the top and wide at the bottom. The outer surface of the fastener 3 is provided with a fastening ring 4 through a conical thread thread sleeve.

[0030] The lower part of the side wall of the pipe body 1 is fixedly connected with an insulation sleeve 6, which is made of insulation material, such as glass wool, rock wool, etc., which can insulate the water inlet and outlet of the pipe and also provide sound insulation.

[0031] The outer surface of the fastening ring 4 is fixed with an anti-slip sleeve 5, which can be made of rubber material.

[0032] Construction principle: During the roof construction process, the pipe body 1 is pre-buried in the roof, leaving the upper part of the pipe body 1 exposed, and then the pipeline connection is carried out after the overall concrete strength of the roof reaches the specified range.

[0033] The construction workers lay the pipeline so that the pipeline and the pipe body 1 are fitted together. Then, the construction workers insert the waterproof component 2 into the pipe body 1 so that the lower end of the waterproof component 2 contacts the upper surface of the annular step on the inner wall of the pipe body 1. The connecting sleeve 202 on the waterproof component 2 is movably fitted on the pipe body 1.

[0034] Then the construction workers put the fastener 3 on the pipe body 1, and the lower surface of the fastener 3 contacts the upper surface of the waterproof part 2. Then the construction workers put the fastening ring 4 on the fastener 3 with a thread. Since the fastener 3 is provided with a conical thread, the construction workers rotate the fastening ring 4, and the fastening ring 4 downward causes the shrinkage seam of the fastener 3 to converge, and the fastener 3 is squeezed inward. After the pipe body 1 is squeezed, since a plurality of strip avoidance openings 102 are opened on the upper part of the pipe body 1, the pipe body 1 also converges inward after being subjected to force. After the waterproof part 2 is inserted into the pipe body 1, the inner wall of the waterproof part 2 contacts the pipe, and the pipe body 1 converges inward, causing the waterproof part 2 to be compressed, thereby improving the sealing.

[0035] When the waterproof part 2 ages after long-term use and a gap is generated between the waterproof part 2 and the pipe, the maintenance personnel can rotate the fastening ring 4 so that the fastening ring 4 continues to move downward, thereby increasing the inward contraction amplitude of the fastener 3, so that the waterproof part 2 is compressed more, thereby reducing the gap between the waterproof part 2 and the pipe.

[0036] When it rains, rainwater falls onto the awning 203 and is guided by the awning 203 to flow around.

[0037] Therefore, the waterproof component 2 can be installed after the pipeline is connected, and then the waterproof component 2 can be compressed by tightening it with the fastener 3, so that the waterproof component 2 can fill the gap between the pipe body 1 and the pipeline as much as possible without interfering with the pipeline connection construction. At the same time, during subsequent use, if leakage occurs due to aging of the waterproof component 2, the sealing can be enhanced by continuing to rotate the fastening ring 4, and the rainwater can be guided to the surroundings through the canopy 203 to reduce the erosion of the pipeline by rainwater.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
