[0025] 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.

[0026] like Figures 1 to 3 As shown, the utility model provides a pipeline plugging device, comprising:

[0027] Bottom plate 1, which is annular, and one side of the bottom plate 1 is used to fit with the end face of the pipe;

[0028] The plug-in structure includes a cylindrical portion 2, a sheet portion 3 and a handle portion 4. One end of the cylindrical portion 2 is connected to the inner periphery of the base plate 1, and the outer periphery of the sheet portion 3 is connected to the other end of the cylindrical portion 2. The handle portion 4 is arranged inside the cylindrical portion 2 and connected to the sheet portion. The outer periphery of the cylindrical portion 2 is provided with blades 5 and a sealing ring 6. The blades 5 are used to clamp with the inner wall of the pipe.

[0029] Specifically, the pipe plugging device provided by the present invention has a base plate 1 and a plugging structure. The plugging structure can be inserted into the pipe, and the blades 5 on the outer periphery of the cylindrical part 2 are clamped with the inner wall of the pipe to prevent it from falling off. At the same time, the sealing ring 6 on the outer periphery of the cylindrical part 2 can form a seal between the cylindrical part 2 and the pipe, playing the role of pipe plugging, and the base plate 1 fits with the end face of the pipe on the outside of the pipe, further improving the sealing effect. When in use, it can be conveniently held by the handle 4; the pipe plugging device is not only easy to install and disassemble, but also can be disassembled and used multiple times, and has a long service life.

[0030] Optionally, the sheet portion 3 is annular, the handle portion 4 is cylindrical with one end closed, and the other end of the handle portion 4 is connected to the inner circumference of the sheet portion.

[0031] Specifically, the handle portion 4 can be integrally formed in the middle of the sheet portion 3 , with the same thickness as the sheet portion 3 , and the handle portion 4 is hidden in the cylindrical portion 2 .

[0032] Optionally, the handle portion 4 is tapered from an end close to the sheet portion 3 to an end away from the sheet portion 3 .

[0033] Specifically, the handle portion 4 adopts a small-angle draft process and is provided with a draft angle, which is beneficial to the production and manufacturing of the product. At the same time, when the inner diameter of the pipe deviates downward, the handle portion 4 can be rotated and installed by hand to reduce the difficulty of installation.

[0034] Optionally, two blades 5 are symmetrically arranged on both sides of the cylindrical portion 2 .

[0035] Specifically, a pair of blades 5 are symmetrically distributed on the two side surfaces of the cylindrical portion 2. The thinner wall thickness ensures that the blades 5 can be deformed when subjected to force, thereby achieving a snap connection in the pipeline.

[0036] Optionally, the blades 5 are fan-shaped.

[0037] Specifically, the inner periphery of the fan-shaped blade 5 is integrally formed with the cylindrical portion 2 , and the outer periphery is snap-fitted with the inner wall of the pipe.

[0038] Optionally, the outer diameter of the blade 5 is larger than the inner diameter of the pipe.

[0039] Specifically, the outer diameter of the blade 5 is larger than the inner diameter of the pipe, and when the plug-in structure is inserted into the pipe, it is deformed to ensure the clamping force.

[0040] Optionally, a notch 7 is provided on the outer circumference of the blade 5 .

[0041] Specifically, the provision of the notch 7 can improve the ability of the blade 5 to undergo local deformation and reduce installation resistance.

[0042] Optionally, the outer edge of the blade 5 is provided with a thinned portion 8 .

[0043] Specifically, such as Figure 4 As shown, the thinning portion 8 can be formed by a beveling method. The provision of the thinning portion 8 makes it easier for the plug-in structure to be locally deformed when inserted into the pipe.

[0044] Optionally, an outwardly protruding limiting portion 9 is provided on the outer periphery of the cylindrical portion 2 , and the sealing ring 6 is provided between the limiting portion 9 and the bottom plate 1 .

[0045] Specifically, the sealing ring 6 is limited by the limiting portion 9 , and the sealing ring 6 is fixed between the limiting portion 9 and the bottom plate 1 .

[0046] In this embodiment, the inner periphery of the sealing ring 6 matches the outer periphery of the cylindrical portion 2. After the sealing ring 6 is sleeved on the outer periphery of the cylindrical portion 2, its outer diameter is larger than the inner diameter of the pipe. After being inserted into the pipe, it can be in close contact with the pipe to ensure a sealing effect and be waterproof and anti-fouling.

[0047] Optionally, the material of the pipeline plugging device is plastic.

[0048] Specifically, the pipeline plugging device is made of plastic, which has low cost and is easy to process.

[0049] 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.
