[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1-6, the utility model provides an embodiment: a pipe port sealing structure, including a pipe body 1, a connecting ring 2 is fixedly connected to the side wall of the pipe body 1, a sealing cover 3 is provided on the top of the connecting ring 2, the connecting ring 2 and the side walls of the sealing cover 3 are fixedly connected with claws 4, the connecting ring 2 and the side walls of the sealing cover 3 are fixedly connected with a clamping plate 5, an annular groove 6 is opened inside the pipe body 1, a sealing ring 7 is fixedly connected to the bottom of the sealing cover 3, the sealing ring 7 is consistent with the annular groove 6, ensuring that the sealing cover 3 can be installed When the sealing ring 7 can be tightly inserted into the annular groove 6, the claws 4 and the clamping plate 5 are They are symmetrically arranged and staggered with each other. The top claws 4 are engaged with the bottom clamping plate 5, and the bottom claws 4 are engaged with the top clamping plate 5. This staggered engagement method forms a mutual lock between the sealing cover 3 and the connecting ring 2, which can effectively prevent the sealing cover 3 from loosening or falling off when subjected to external force, thereby improving the sealing reliability. A positioning mechanism is provided at the bottom of the sealing cover 3 to limit the rotation angle of the sealing cover 3 to prevent excessive or insufficient rotation from affecting the sealing effect. A limiting groove 8 is provided inside the connecting ring 2. The function of the limiting groove 8 is to The limit block 11 provides a guide channel to ensure that the sealing cover 3 can remain in the predetermined track when rotating. An insertion groove 9 is opened inside the connecting ring 2. The insertion groove 9 is connected to the limit groove 8 to form a continuous channel structure. When the sealing cover 3 is installed, the limit block 11 first enters through the insertion groove 9 and aligns with the limit groove 8, so that the sealing cover 3 can ensure correct alignment during the initial installation. A positioning hole 10 is opened inside the connecting ring 2. The positioning mechanism includes a limit block 11. The side wall of the limit block 11 is fixedly connected to the bottom of the sealing cover 3, and the side wall of the limit block 11 slides Connected to the inside of the limiting groove 8 and the insertion groove 9, the limiting block 11 is slidably connected to the inside of the positioning block 11, and the side wall of the positioning block 12 is fixedly connected to the connecting column 13. The side wall of the positioning block 12 is slidably connected to the inside of the positioning hole 10, and the side wall of the connecting column 13 is sleeved with a spring 14. The function of the spring 14 is to provide a certain rebound force for the positioning block 12 to ensure that when the sealing cover 3 is rotated to the specified position, the positioning block 12 can quickly return to its initial position to form a lock. One end of the spring 14 is fixedly connected to the side wall of the positioning block 12, and the other end of the spring 14 is fixedly connected to the inside of the limiting block 11.

[0034] When sealing the end portion of the pipe body 1, it is first necessary to correctly align the sealing cover 3 with the connecting ring 2, so that the limit block 11 at the bottom of the sealing cover 3 is aligned with the insertion groove 9 opened inside the connecting ring 2. The insertion groove 9 ensures the smooth insertion of the limit block 11 and provides an initial guide for subsequent installation. When the limit block 11 is aligned with the insertion groove 9, press the sealing cover 3 downward. During the pressing process, the limit block 11 will gradually slide into the interior of the insertion groove 9. At the same time, the positioning block 12 inside the limit block 11 will also be squeezed and compressed into the internal space of the limit block 11. As the pressing continues, the bottom of the sealing cover 3 gradually approaches the top of the connecting ring 2, and the sealing ring 7 at the bottom of the sealing cover 3 also enters the annular groove 6 opened at the end of the pipe body 1. The cooperation between the sealing ring 7 and the annular groove 6 ensures that the sealing cover 3 is tightly fitted with the end of the pipe body 1, thereby forming a preliminary sealing structure. After the sealing cover 3 is fitted with the connecting ring 2, the sealing cover 3 is rotated. As the sealing cover 3 rotates, the claw 4 at the top of the sealing cover 3 slides along the outer surface of the connecting ring 2. The design of the claw 4 enables it to gradually approach and finally engage with the card plate 5 on the connecting ring 2. When the sealing cover 3 continues to rotate, the top claw 4 and the card plate 5 on the connecting ring 2 When the locking cam 12 is in the closed position, the spring 14 in the locking cam 11 starts to be reset. Since the spring 14 is compressed when pressed, the spring 14 will automatically reset as the pressure is released, pushing the positioning block 12 to move downward. When the positioning block 12 is inserted into the positioning hole 10, the rotation of the sealing cover 3 is restricted, and the sealing cover 3 can stop rotating, completing the installation.

[0035] Working principle: When sealing the end portion of the pipe body 1, first align the limit block 11 at the bottom of the sealing cover 3 with the insertion groove 9 opened inside the connecting ring 2, and then press the sealing cover 3 downward so that the limit block 11 is inserted into the inside of the insertion groove 9 and the positioning block 12 is pressed into the inside of the limit block 11. At this time, the sealing ring 7 at the bottom of the sealing cover 3 will be inserted into the annular groove 6 opened at the end portion of the pipe body 1, and the sealing cover 3 will fit the connecting ring 2. At this time, the sealing cover 3 is rotated to make the top claw 4 slide on the outside of the connecting ring 2, and gradually engage with the clamping plate 5 on the connecting ring 2 as it rotates. At this time, the claw 4 on the connecting ring 2 will also engage with the clamping plate 5 on the sealing cover 3, thus completing the connection between the connecting ring 2 and the sealing cover 3.

[0036] As the sealing cover 3 rotates, when the positioning block 12 inside the limit block 11 moves to above the positioning hole 10 opened inside the connecting ring 2, the spring 14 inside the limit block 11 will reset due to the loss of pressure, and push the positioning block 12 downward and insert it into the positioning hole 10, thereby achieving the positioning of the sealing cover 3. At this time, the sealing work of the end part of the pipe body 1 is completed.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
