Description

TECHNICAL FIELD

[0001] The present application relates to pipe sealing, in particular to a pipe opening sealing and water stopping tool. BACKGROUND

[0002] Some indoor pipe openings need to be temporarily sealed, for example, the sewer pipe of a bathroom needs to be temporarily sealed to conduct water seepage test. The existing sealing tools are either not tightly sealed or need to be damaged to open after sealing, and cannot be reused. SUMMARY

[0003] The purpose of the present application is to provide a pipe opening sealing and water stopping tool which can seal the pipe opening in two ways, is easy to operate and can be reused.

[0004] The technical scheme adopted by the present application is as follows:

[0005] A pipe opening sealing and water stopping tool comprises a water stopping bowl made of plastic material, the water stopping bowl is a rotary body and the cross section along the rotary center is in the shape of a "bow", one side of the water stopping bowl is provided with an annular groove and the other side is provided with a central groove; a pull rope is fixed at the center position of the water stopping bowl, the central groove is filled with sealing silica gel, the pull rope is straightly pulled out of the central groove, and the sealing silica gel wraps the pull rope inside; the back of the annular groove of the water stopping bowl is provided with an annular sponge sealing layer, the inner ring of the sponge sealing layer is in contact with the sealing silica gel, and the outer ring is larger than the inner diameter of the pipe; the outer diameter of the water stopping bowl at the front end of the annular groove is larger than the inner diameter of the pipe, and the outer diameter of the water stopping bowl at the back end is equal to or smaller than the inner diameter of the pipe.

[0006] Preferably, the sponge sealing layer is adhered to the water stopping bowl by waterproof glue.

[0007] Preferably, the pull rope is provided with an enlarged portion at the pull-out end for easy pulling.

[0008] Preferably, the enlarged portion is a pull ring, a ball head or a knot.

[0009] When temporarily sealing the pipe, the central groove is outward and the annular groove is inward, the water stopping bowl is pressed into the pipe until the sponge sealing layer is completely located inside the pipe opening, the sponge sealing layer is in close contact with the inner wall of the pipe to form the first sealing, and the water stopping bowl at the front end of the annular groove is in close contact with the inner wall of the pipe under the elastic action of itself to form the second sealing; when the temporary sealing needs to be cancelled, the pull rope is operated to pull out the water stopping bowl outside the pipe opening.

[0010] The present application has the following beneficial effects:

[0011] This tool can provide two seals to the pipe opening, is easy to operate, and can be reused. The first seal is achieved using a sponge sealing layer, and the second seal is achieved using the elasticity of the water-stop bowl itself. The function of the sealing silicone is threefold: first, to prevent water accumulation in the central groove; second, to prevent water leakage at the location of the pull rope fixing end; and third, and most importantly, to provide support for the center of the water-stop bowl, preventing uneven deformation around the water-stop bowl due to stress.

[0014] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0015] A pipe opening sealing and waterproofing tool, including a waterproofing cup made of plastic, such as... Figure 1 As shown, the water-stop bowl is a rotating body with a "bow"-shaped cross-section along the center of rotation. One side of the water-stop bowl has an annular groove, and the other side has a central groove. A pull rope is fixed at the center of the water-stop bowl, and the central groove is filled with sealing silicone. The pull rope extends straight out of the central groove, and the sealing silicone wraps around the pull rope inside. An annular sponge sealing layer is provided on the back of the annular groove on the water-stop bowl. The inner circle of the sponge sealing layer contacts the sealing silicone, and the outer circle is larger than the inner diameter of the pipe. The outer diameter of the water-stop bowl at one end of the annular groove on the front is larger than the inner diameter of the pipe, and the outer diameter at the other end on the back is equal to or smaller than the inner diameter of the pipe.

[0016] In this embodiment, the sponge sealing layer is bonded to the water-stop bowl with waterproof adhesive. In this embodiment, the extended end of the pull rope is provided with an enlarged portion for easy pulling; the enlarged portion can be a pull ring, a ball head, a knot, etc.

[0017] When temporarily sealing the pipe, with the central groove facing outward and the annular groove facing inward, press the water-stop bowl into the pipe until the sponge sealing layer is completely inside the pipe opening. The sponge sealing layer will form a first seal by making close contact with the inner wall of the pipe. The water-stop bowl will also form a second seal by making close contact with the inner wall of the pipe at one end of the annular groove due to its own elasticity. When it is necessary to remove the temporary seal, simply pull the rope to pull the water-stop bowl out of the pipe opening.

[0018] The tool can seal the pipe opening in two ways, is convenient to operate and can be repeatedly used; the first sealing is realized by using the sponge sealing layer, and the second sealing is realized by using the elasticity of the water stop bowl; the sealing silica gel has the following effects: first, preventing water accumulation in the center groove; second, preventing water leakage at the position where the fixed end of the pull rope is located; and third, most importantly, providing support for the center of the water stop bowl to avoid uneven deformation of the periphery of the water stop bowl.
