[0025] See also Figure 1 and Figure 2As shown, an embodiment of the utility model provides a new type of compression-type connecting pipe structure, which specifically includes a connecting tube 1, and two symmetrical connecting pipes 2 are arranged inside the connecting tube 1. When connecting the two connecting pipes 2, the two connecting pipes 2 are respectively inserted into the connecting tube 1 from both ends, which can facilitate the subsequent connection of the two connecting pipes 2. A sealing ring 3 is fixedly connected to the inner wall of the connecting tube 1, and a first sealing ring 4 is installed on the left and right sides of the sealing ring 3. A second sealing ring 5 is installed at one end of the two connecting pipes 2 that are close to each other, and the second sealing ring 5 is in contact with the first sealing ring 4. Specifically in this embodiment, when the connecting pipe 2 is inserted into the interior of the connecting tube 1, the second sealing ring 5 at the end of the connecting pipe 2 is in contact with the sealing ring 3 installed on the outer surface of the sealing ring 3, so that the first sealing ring 4 and the second sealing ring 5 are compressed against each other, which can facilitate the sealing of the connection between the connecting pipe 2 and the sealing ring 3.

[0026] See also Figure 2 and Figure 4 As shown, a clamping assembly 6 is installed between the two connecting pipes 2 and the connecting tube 1. The clamping assembly 6 specifically includes a guide groove 601 provided on the outer surface of the connecting pipe 2, and a clamping groove 602 is provided on the inner wall of the guide groove 601. The clamping assembly 6 also includes a cylinder 603 fixedly embedded on the outer surface of the connecting tube 1. A slide plate 604 is slidably connected to the inner wall of the cylinder 603. A clamping rod 605 is installed on the outer surface of the slide plate 604. One end of the clamping rod 605 away from the slide plate 604 is clamped with the inner wall of the clamping groove 602. One end of the clamping rod 605 away from the slide plate 604 penetrates the inner wall of the cylinder 603 and extends to the outside of the cylinder 603. The outer surface of the clamping rod 605 is slidably connected to the penetration point of the cylinder 603. Specifically in this embodiment, when the connecting tube 2 is inserted into the interior of the connecting tube 1, the clamping rod 605 can slide into the interior of the guide groove 601, so that the clamping rod 605 can be contracted to a certain extent toward the interior of the cylinder 603. When the connecting tube 2 moves to the position where the clamping rod 605 corresponds to the clamping groove 602, the clamping rod 605 can be inserted into the interior of the clamping groove 602, so as to limit the connection between the connecting tube 1 and the connecting tube 2.

[0027] See also Figure 4As shown, a pull rod 606 is installed at one end of the slide plate 604 away from the clamping rod 605, and a pull ring 607 is installed at one end of the pull rod 606 away from the slide plate 604. The end of the pull rod 606 away from the slide plate 604 penetrates the inner wall of the cylinder 603 and extends to the outside of the cylinder 603. The outer surface of the pull rod 606 is slidably connected to the penetration point of the cylinder 603. When in use, the pull ring 607 is pulled outward, and the pull ring 607 can drive the slide plate 604 and the clamping rod 605 to move through the pull rod 606, so that the clamping rod 605 can be separated from the inside of the clamping groove 602, and the limit of the connecting pipe 2 can be released, so that the connecting pipe 2 can be easily removed. A spring 608 is sleeved on the outer surface of the pull rod 606, and the two ends of the spring 608 are respectively connected to the outer surface of the slide plate 604 and the inner wall of the cylinder 603. The spring 608 is provided to provide elastic force to the slide plate 604, to ensure the clamping effect between the clamping rod 605 and the clamping groove 602, and to ensure the limiting effect on the connected pipe 2. The inner wall of the cylinder 603 is provided with two symmetrical slide grooves 609, and the inner walls of the two slide grooves 609 are slidably connected with sliders 610, and the sliders 610 are connected to the slide plate 604. When the slide plate 604 slides on the inner wall of the cylinder 603, the sliders 610 can slide on the inner walls of the slide grooves 609, and the slide plate 604 can be guided and limited, so as to ensure the stability of the slide plate 604 and the clamping rod 605 when moving.

[0028] See also Figure 3 As shown, the outer surfaces of the two connecting pipes 2 are fixedly connected with positioning strips 7, and the inner wall of the connecting tube 1 is equipped with two positioning components 8, which specifically include a positioning ring 801 fixedly connected to the inner wall of the connecting tube 1, and the inner wall of the positioning ring 801 is provided with two symmetrical positioning grooves 802, and the positioning grooves 802 are adapted to the positioning strips 7. Specifically in this embodiment, when the connecting pipes 2 are connected, when the connecting pipes 2 are inserted into the interior of the connecting tube 1, the positioning strips 7 can be inserted into the interior of the connecting tube 1 from the interior of the positioning grooves 802, and the connecting pipes 2 can be limited and guided by the provided positioning strips 7 and positioning grooves 802, which can ensure that the clamping rod 605 successfully slides into the interior of the guide groove 601, and the connecting pipes 2 can be conveniently limited.

[0029] The specific working principle of the utility model is as follows: when in use, the two connecting pipes 2 to be connected are respectively inserted into the interior of the connecting tube 1 from the two ends of the connecting tube 1. When the connecting pipes 2 are inserted into the interior of the connecting tube 1, the positioning strip 7 can be inserted into the interior of the positioning groove 802, which can guide the connecting pipes 2. When the connecting pipes 2 are inserted into the interior of the connecting tube 1, the clamping rod 605 can slide into the interior of the guide groove 601, so that the clamping rod 605 can be retracted to a certain extent toward the interior of the cylinder 603, so that the slide plate 604 can be elastically pressed. The spring 608 is compressed to a certain extent. When the connecting pipe 2 moves to the position where the clamping rod 605 corresponds to the clamping slot 602, the slide plate 604 and the clamping rod 605 can be reset under the elastic force of the spring 608, and the clamping rod 605 can be inserted into the interior of the clamping slot 602, so as to limit the position between the connecting tube 1 and the connecting pipe 2, thereby facilitating the connection between the connecting tube 1 and the connecting pipe 2, allowing the two connecting pipes 2 to be connected, and facilitating the connection of the two connecting pipes 2, thereby facilitating the use of the structure.
