[0002] In the existing market, in people's daily life and in the daily processing work of factories, it is generally necessary to transfer water and gas generated in daily work through pipes. Since the length of pipes is generally fixed during production, pipes generally need to be connected to each other in actual use. During the connection, since the substances transferred by the pipes are not all harmless and non-toxic, it is necessary to ensure that the pipes are connected to each other through sealing devices. In order to ensure the sealing effect between pipes, the sealing devices on the existing market generally only insert the sealing rubber plug between the pipe and the connecting mechanism to complete the sealing work during the sealing. However, the above-mentioned sealing work directly squeezed by rubber often causes the sealing plug to be squeezed in. The position is not uniform, so local leakage still occurs.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 , the utility model provides a technical solution: a pipeline leakage sealing device, comprising a sealing body 1, which is in a hollow cylindrical structure as a whole;

[0028] Also includes:

[0029] The sealing mechanism 3 is arranged at the top positions of both sides of the sealing body 1, and is used to fit tightly with the pipes to be connected, so as to achieve the sealing and leakage prevention work between the connected pipes;

[0030] The sealing body 1 is provided with a mounting thread 11 and a moving mechanism 12, and the mounting thread 11 and the moving mechanism 12 are sequentially arranged from the inside to the outside inside the sealing body 1;

[0031] The sealing mechanism 3 is arranged in a trumpet-shaped structure and is moved by the moving mechanism 12 to achieve the effect of squeezing and sealing the sealed pipe to prevent leakage.

[0032] The mounting thread 11 is used for connecting the entire sealing body 1 with an external pipe. The moving mechanism 12 includes a moving slider 121 and a moving groove 122. The moving groove 122 is embedded in the inner wall of the sealing body 1 and has a sliding moving slider 121 disposed therein. The top of the moving slider 121 is connected to the sealing mechanism 3.

[0033] There are five moving mechanisms 12 distributed at equal angles on the top of one side of the sealing body 1;

[0034] Specifically, the thread 11 is installed to facilitate connection with external pipes, and the moving mechanism 12 can be used to move the sealing mechanism 3 inward.

[0035] The sealing device also includes:

[0036] The trigger mechanism includes a rotating mechanism 2 and a connecting mechanism 4 . The connecting mechanism 4 is connected to the top of the moving mechanism 12 , and the top of the other side of the connecting mechanism 4 is moved by the control of the rotating mechanism 2 .

[0037] The rotating mechanism 2 comprises:

[0038] The rotating cover 21 is located at the bottom middle of the sealing body 1, and the outer surface of the rotating cover 21 is penetrated by thread grooves 23 at equal angles;

[0039] A fastening bolt 22 is disposed inside the thread groove 23 for fastening the sealing body 1 .

[0040] A connecting mechanism 4 is installed at the bottom of the rotating cover 21 . The connecting mechanism 4 includes a connecting block 41 and a connecting line 42 . Two connecting blocks 41 are provided, and are connected to two movable sliders 121 on both sides of the outside of the sealing body 1 through the connecting lines 42 .

[0041] The sealing mechanism 3 includes a connecting cover 31 and a sealing pad 32. The connecting cover 31 is arranged in an arc-shaped structure, and five of them form a group. A sealing pad 32 having a larger arc than the connecting cover 31 is arranged at the bottom of the connecting cover 31. The top of the connecting cover 31 is connected to the moving slider 121.

[0042] The material of the connection cover 31 is PVC;

[0043] Specifically, it is convenient to control the connection mechanism 4 through the rotating mechanism 2 to pull the moving mechanism 12 to move, so that the sealing gasket 32 ​​evenly enters the gap between the pipeline and the sealing body 1, thereby achieving an efficient sealing effect.

[0044] Working principle: When using the pipeline leakage sealing device, the top ends of the two pipelines to be sealed are respectively passed through the middle of the sealing mechanism 3 into the interior of the sealing body 1, and then the installation threads 11 inside the sealing body 1 are threadedly connected with the threads outside the pipeline to complete the connection between the pipeline and the entire sealing body 1. After the connection is completed, the pipeline needs to be sealed. When sealing, the staff needs to rotate the rotating cover 21 on the rotating mechanism 2 so that the rotating cover 21 drives the connecting block 41 at its bottom to slide in the slide groove outside the sealing body 1. When the connecting block 41 slides, since the connecting block 41 is connected to the moving slider 121 through the connecting line 42, it will also drive the moving slider 121. The movable slider 121 slides inside the movable groove 122. When sliding, since the movable slider 121 is connected to the connecting cover 31, the connecting cover 31 drives the sealing gasket 32 ​​at its bottom to slowly move into the inside of the sealing body 1. When moving, the inner wall of the sealing body 1 squeezes the connecting cover 31 to bend downward, thereby making the sealing gasket 32 ​​move downward and squeeze and contact with the outer wall of the connecting pipe outside, thereby achieving a sealing effect. At the same time, since the entire sealing gasket 32 ​​moves from the inside to the outside, its internal cross-section is a conical structure with a small inner part and a large top, which further ensures the uniformity of the sealing gasket 32 ​​inside the gap, thereby ensuring a better sealing effect.

[0045] When the rotating cover 21 is moved to a suitable position, at this time, it is only necessary to control the fastening bolts 22 to pass through the thread grooves 23 on the surface of the rotating cover 21 to complete the thread fastening work. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
