[0002] Pipe sealing mechanisms are specialized equipment or systems used for pipe sealing. They typically include a variety of components and technologies to ensure that pipes can be effectively sealed during specific operations or maintenance.

[0003] During pipeline maintenance or repair, sealing mechanisms can be used to isolate specific pipe sections to ensure the safe conduct of maintenance work. In the event of a pipeline leak, sealing mechanisms can respond quickly and seal the leak point to prevent the leak from spreading and causing greater damage. When conducting pipeline pressure tests or leak tests, sealing mechanisms can be used to isolate the test area to ensure the accuracy and safety of the test.

[0004] When a pipe plugging mechanism is installed on a pipe, an unstable installation of the plugging mechanism can cause it to slip out of its plugging position or even fall off, resulting in pipe plugging failure.

[0005] Therefore, this utility model provides a sealing mechanism for pipe processing. Utility Model Content

A sleeve is fixedly installed in the middle of the connecting seat. A push rod is slidably fitted in the sleeve along the axial direction. An arc-shaped first clamping piece is fixedly installed at the end of the push rod away from the connecting seat, and a spring is fixedly installed at the other end.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a sealing mechanism for pipe processing according to this utility model includes a collar 12. A base plate 11 is concentrically fixedly installed at one end of the collar 12. A through hole is opened in the middle of the base plate 11. A plug 18 is fixedly installed in the through hole. The plug 18 is cylindrical and the end of the plug 18 away from the base plate 11 is sealed. An annular airbag 4 is fixedly installed in the middle of the outer side of the plug 18. An air pump 41 is fixedly installed in the plug 18. An air pipe 42 is fixedly installed at the output end of the air pump 41. The other end of the air pipe 42 passes through the plug 18 and communicates with the airbag 4.

[0025] Multiple connecting seats 13 are evenly fixedly installed on the inner wall of the collar 12 along the circumference. A sleeve 14 is fixedly installed in the middle of the connecting seat 13. A push rod 16 is slidably fitted inside the sleeve 14 along the axial direction. There are multiple ways to install the sleeve 14 and the push rod 16. For example, a ring platform is fitted on the inner side of the end of the sleeve 14 away from the collar 12. A fixing ring is fixedly fitted on the end of the push rod 16 inside the sleeve 14. The sleeve 14 and the push rod 16 are prevented from separating by the cooperation of the ring platform and the fixing ring. An arc-shaped first clamping piece 1 is fixedly installed on the end of the push rod 16 away from the connecting seat 13, and a spring 15 is fixedly installed on the other end. The other end of the spring 15 is fixedly connected to the connecting seat 13. Multiple first rubber blocks 17 are arranged in an array on the inner ring surface of the first clamping piece 1.

[0026] In use, pushing the first clamp 1 compresses the spring 15, causing the push rod 16 to slide into the sleeve 14, which then places the collar 12 on the end of the pipe. At this point, the plug 18 extends into the pipe, and the spring 15 rebounds and extends, causing the push rod 16 to slide out of the collar 12. The push rod 16 then causes the first clamp 1 to press against the outer wall of the pipe. Then, the air pump 41 is started, and the air pump 41 sends high-pressure gas through the air pipe 42 into the airbag 4. The airbag 4 expands and fills the gap between the plug 18 and the inner wall of the pipe, thus sealing the pipe. By setting up the airbag 4, the first clamp 1, and the push rod 16, not only is the sealing effect on the pipe enhanced, but the outer wall of the pipe is also clamped and fixed, reducing the misalignment and sliding of the collar 12 and increasing the stability of the collar 12 at the end of the pipe. This solves the problem of sealing failure caused by the plug 18 sliding out of the pipe due to the misalignment and sliding of the collar 12.

[0027] like Figures 4 to 6 As shown, multiple grooves 21 are evenly formed along the circumference on the outer side wall of the plug 18. An electric telescopic rod 22 is fixedly installed radially inside the groove 21. An arc-shaped second clamping piece 2 is fixedly installed at the output end of the electric telescopic rod 22. Multiple second rubber blocks 23 are arranged in an array on the outer ring surface of the second clamping piece 2. In use, the plug 18 is inserted into the pipe, and the electric telescopic rod 22 is activated. The electric telescopic rod 22 extends and drives the second clamping piece 2 to squeeze the inner wall of the pipe, thereby further increasing the stability of the collar 12 at the end of the pipe and reducing the misalignment and slippage of the collar 12.

[0028] like Figure 1 , Figure 2 , Figure 4 As shown, a waterproof elastic cloth 3 is fixedly installed at the end of the plug 18, and the edge of the waterproof elastic cloth 3 is fixedly connected to the base plate 11, so that the waterproof elastic cloth 3 is set in a frustum shape; when the plug 18 is inserted into the pipe, the waterproof elastic cloth 3 is located between the surface of the plug 18 and the inner wall of the pipe, thereby further reducing the problem of water overflow in the pipe.

[0029] Working principle: When the sealing mechanism is in use, the first clamping plate 1 is pushed, at which time the spring 15 is compressed and drives the top rod 16 to slide into the sleeve 14, and the collar 12 is put on the end of the pipe. At this time, the plug 18 extends into the pipe. The spring 15 rebounds and extends, driving the top rod 16 to slide out from the collar 12. The top rod 16 drives the first clamping plate 1 to squeeze the outer wall of the pipe. Then, the electric telescopic rod 22 is activated. The electric telescopic rod 22 extends and drives the second clamping plate 2 to squeeze the inner wall of the pipe. The symmetrically arranged electric telescopic rods 22 realize the compression and fixation of the inner wall of the pipe. Then, the air pump 41 is activated. The air pump 41 inputs high-pressure gas into the air bag 4 through the air pipe 42. The air bag 4 expands to fill the gap between the plug 18 and the inner wall of the pipe, and under the action of the waterproof elastic cloth 3, the pipe is sealed.

[0030] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1 As shown, multiple anti-slip rubber rings 5 ​​are fixedly fitted along the axial direction on the outer wall of the collar 12; by providing anti-slip rubber rings 5, the resistance can be increased and the slippage reduced when installing and removing the collar 12, making the installation and removal of the collar 12 faster.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
