[0021] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0022] like Figure 1 As shown, the utility model provides a pipe blocking device, comprising:

[0023] The cylindrical portion 1 has a sealing layer 2 on its inner wall at one end and is used to be sleeved on the outside of the pipe 3;

[0024] The plugging plate has an outer periphery connected to the inner periphery of the cylindrical portion 1, and the plugging plate is provided with a protrusion. An annular positioning groove 4 is formed between the protrusion and the cylindrical portion 1, and the positioning groove 4 is used to insert the pipe 3;

[0025] The pipe hoop 5 is provided on the outside of the cylindrical portion 1 .

[0026] Specifically, the pipe plugging device provided by the present invention can be sleeved on the outside of the pipe 3 through the cylindrical part 1, and the sealing layer 2 is in contact with the outer wall of the pipe 3, and is inserted into the inside of the pipe 3 through the raised part to play a positioning and supporting role. When the pipe clamp 5 is sleeved on the outside of the cylindrical part 1 and tightened, the cylindrical part 1 is deformed, pressing the sealing layer 2 to achieve pipe blocking, and at the same time the raised part is positioned and supported inside the pipe 3; the pipe plugging device has a simple structure and low cost, is not only convenient to install and disassemble, but also can be used multiple times and has a long service life.

[0027] In this embodiment, the pipe plugging device facilitates installation and positioning at the end of the pipe 3 through the positioning groove 4 formed on the outer periphery of the raised portion, and then locks the sealing layer 2 by the pipe clamp 5 to increase the compression force and friction force to achieve fixation and waterproof and anti-fouling effects; the pipe clamp 5 can be produced separately or purchased from outside, and then assembled on the outside of the cylindrical portion 1, which is very convenient to produce and assemble.

[0028] Furthermore, compared with similar devices, the pipe plugging device increases the contact area between the sealing layer 2 and the pipe 3, while applying a compressive force around the pipe 3, and the sealing force is greater than that of similar products.

[0029] Optionally, the cylindrical portion 1 and the blocking plate are formed integrally.

[0030] Specifically, the cylindrical portion 1 and the blocking plate are formed in one piece, which is simple in process and low in cost.

[0031] Optionally, the blocking plate includes an annular portion 6, a cylindrical portion 7 and a disc portion 8, the two ends of the cylindrical portion are respectively connected to the inner periphery of the annular portion 6 and the outer periphery of the disc portion 8, and the disc portion 8 and the cylindrical portion 7 form a convex portion.

[0032] Specifically, the annular portion 6 , the cylindrical portion 7 and the disc-shaped portion 8 have the same thickness, and the material thickness is uniform. During molding, only upper and lower molds are required, and no core-pulling structure is required.

[0033] Optionally, the blocking plate is provided with a handle portion 9 .

[0034] Specifically, the arrangement of the handle portion 9 can provide a gripping position, further improving the convenience of installation and disassembly.

[0035] Optionally, the handle portion 9 is provided inside the cylindrical portion 1 .

[0036] Specifically, the raised portion is arranged on one side of the blocking plate, and the handle portion 9 is arranged on the other side of the blocking plate. When in use, the handle portion 9 is exposed for easy gripping, and the handle portion 9 does not extend out of the cylindrical portion 1 and does not take up too much space.

[0037] Optionally, the handle portion 9 is integrally formed with the blocking plate.

[0038] Specifically, the handle portion 9 can also be integrally formed on the blocking plate to simplify the processing technology.

[0039] Optionally, an annular mounting groove 10 is provided on the outer side of the cylindrical portion 1 , and the mounting groove 10 is used to accommodate the pipe clamp 5 .

[0040] Specifically, the installation groove 10 can indicate and limit the installation position of the pipe clamp 5, making it easier to install and lock the pipe clamp 5.

[0041] Optionally, the material of the cylindrical portion 1 is plastic, and the material of the sealing layer 2 is rubber.

[0042] Specifically, the cylindrical portion 1 and the integrally formed blocking plate and handle portion 9 can all be made of plastic material, which is convenient for processing and has no hidden danger of rust. The sealing layer 2 is made of rubber material and has a cylindrical structure. The sealing layer 2 is located inside the cylindrical portion 1, and the aging speed is slowed down, thereby increasing the service life of the sealing layer 2.

[0043] In summary, the pipe plugging device has a handle portion 9 when in use, which can be installed and disassembled conveniently and labor-savingly. The structural positioning makes it quick to install, and the raised portion forms a positioning support inside, so that the clamping force in all directions is consistent, and the force is applied to the pipe wall evenly, which is not easy to leak from a weak point; the pipe clamp 5 is prevented from falling off by providing an installation groove 10, and the installation efficiency is improved; compared with the threaded pipe plug, it has a larger pipe wall contact area, and at the same time, a clamping force is applied to the outside of the pipeline 3. The sealing force is greatly enhanced under the action of the locking force of the pipe clamp 5 and the large contact area, and it can be used for pipes of any shape.

[0044] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
