The prior art sets up a sealing assembly, wherein bolt one and nut two are used to fasten the sleeve plate and the connecting pipe, and the sealing groove is used in conjunction with a sealing ring to ultimately achieve a sealing effect on the connecting pipe.

However, when installing pipelines of different sizes, sleeve plates with sealing grooves of different sizes need to be replaced to ensure the sealing of the pipelines after docking. This method increases the operating steps when docking the pipelines and reduces the efficiency of docking the pipelines. In view of the above problems, the inventors have designed a simple-to-operate multi-size pipeline fixing connector. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a multi-size pipeline fixed connector with simple operation, including a connecting pipe 1, which is used for connecting two pipelines. A built-in baffle 2 is fixedly connected in the connecting pipe 1, and the outer surface of the built-in baffle 2 is in contact with the inner wall of the connecting pipe 1. A plurality of sleeve rings 3 are fixedly installed on the opposite side surfaces of the built-in baffle 2, and the plurality of sleeve rings 3 are equidistant and radially arranged on the sleeve ring 3, and the outer surface of the sleeve ring 3 is in contact with the inner wall of the pipeline. A plurality of through holes 4 are opened on the built-in baffle 2. When it is needed, the two pipelines are docked by inserting the pipeline into the corresponding sleeve ring 3, and the pipeline on the other side is also inserted into the corresponding sleeve ring 3 on the other side of the built-in baffle 2, so as to complete the docking of the two pipelines. When liquid is transported in the pipeline, the liquid can flow along the through hole without affecting the flow of the liquid. Therefore, when installing pipelines of different sizes, it is only necessary to sleeve the pipeline on the corresponding sleeve ring 3, so that the installation of pipelines of different sizes can be completed. At the same time, there is no need to install the corresponding sealing assembly on the outer side of the connecting pipe 1, which reduces the operation steps of the pipelines when docking and improves the efficiency of the pipeline docking.

[0023] More preferably, a sealing rubber ring is sleeved on the outer surface of the sleeve ring 3, which increases the sealing between the outer surface of the sleeve ring 3 and the inner wall of the pipe, avoids leakage when transporting liquid, and ensures the use effect of the connector.

[0024] Specifically, a fixing component is provided on the connecting tube 1, and the fixing component includes two control rings 5. The two control rings 5 ​​are sleeved on the outer surface of the connecting tube 1. Two thread grooves are provided on the outer surface of the connecting tube 1, and the threads of the two thread grooves are oppositely arranged. The two control rings 5 ​​are respectively threadedly sleeved on the two thread grooves, so that when the two control rings 5 ​​are rotated, the control rings 5 ​​will be displaced on the connecting tube 1 under the transmission of the thread grooves. At the same time, since the threads of the two thread grooves are oppositely arranged, when the two control rings 5 ​​rotate in the same direction, the two control rings 5 ​​are displaced in relative directions under the transmission of the two thread grooves.

[0025] Specifically, an annular bevel groove 11 is provided on the opposite surfaces of the two control rings 5, and four pushing slide bars 6 in a circular array are provided on the outer surface of the connecting pipe 1 near the annular bevel groove 11. One end of the pushing slide bar 6 contacts the inclined surface of the annular bevel groove 11, and the other end slides through the connecting pipe 1. An arc-shaped extrusion plate 7 is fixedly connected to one end of the pushing slide bar 6 located in the connecting pipe 1. When the two control rings 5 ​​are displaced in relative directions, the inclined surface of the annular bevel groove 11 will squeeze the pushing slide bar 6, so that the pushing slide bar 6 gradually moves into the connecting pipe 1, so that the pushing slide bar 6 can drive the arc-shaped extrusion plate 7 to squeeze the outer surface of the pipe, thereby completing the fixation of the pipe, avoiding the problem of loosening after the pipe docking as much as possible, and ensuring the stability of the pipe after docking.

[0026] Specifically, a compression chamber 8 is opened in the inner wall of the connecting pipe 1 near the pushing slide rod 6, and the pushing slide rod 6 is arranged in the compression chamber 8. A movable slide plate 9 is fixedly sleeved on the outer surface of the pushing slide rod 6 located in the compression chamber 8. The movable slide plate 9 slides in the compression chamber 8. A spring 10 is fixedly connected between the movable slide plate 9 and the inner wall of the compression chamber 8. The spring 10 is movably sleeved on the outer surface of the pushing slide rod 6, and the spring 10 is arranged near the inner side of the connecting pipe 1. When the spring 10 is not squeezed, the spring 10 will form a thrust on the movable slide plate 9, so that the initial position of the movable slide plate 9 is on the side away from the inside of the connecting pipe 1. At the same time, when the pushing slide rod 6 pushes the arc extrusion plate 7 to squeeze the pipeline, the spring 10 will squeeze the movable slide plate 9 and shrink. When the two control rings 5 ​​move in opposite directions, the annular inclined groove 11 no longer squeezes the pushing slide rod 6, so that the pushing slide rod 6 moves to the initial position under the push of the spring 10.

[0027] Specifically, two push rods 12 are fixedly connected to the adjacent outer surfaces of the two control rings 5, and a push cross block 13 is provided at the other end of the two push rods 12. A limiting groove 14 is opened on the surface of the push cross block 13 facing the push rod 12. The cross section of the limiting groove 14 is arc-shaped, and a sliding ball 15 is fixedly connected to the end of the push rod 12 close to the pushing cross block 13. The sliding ball 15 is adapted to the limiting groove 14 and slides in the limiting groove 14. In this way, the staff can synchronously drive the two control rings 5 ​​to rotate by rotating the pushing cross block 13. Since the two control rings 5 ​​will move in relative or opposite directions when rotating, the sliding ball 15 can slide in the limiting groove 14 at this time.

[0028] The working principle of the multi-size pipe fixing connector with simple operation provided by the utility model is as follows: when the two control rings 5 ​​are rotated in the same direction, the two control rings 5 ​​are displaced in relative directions under the transmission of the two threaded grooves, and the inclined surface of the annular inclined groove 11 will squeeze the push slide rod 6, so that the push slide rod 6 gradually moves into the connecting pipe 1, so that the push slide rod 6 can drive the arc-shaped extrusion plate 7 to squeeze the outer surface of the pipe, thereby completing the fixation of the pipe.
