[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5As shown, this utility model provides a medical suction tube connector, including a first mounting cover 1 and a second mounting cover 2. The first mounting cover 1 and the second mounting cover 2 are threaded together to form a whole, and an intermediate chamber is provided between the first mounting cover 1 and the second mounting cover 2. The front of the second mounting cover 2 is connected to a rear connecting sleeve 3.

The diameters of each front connecting sleeve 4 are different. An assembly fixing sleeve 5 is fixedly provided on the outside of the front connecting sleeve 4. An adsorption fixing component 7 is fixedly provided on the front of the first mounting cover 1. The adsorption fixing component 7 is connected to the assembly fixing sleeve 5.

The through hole 54 is opened in the fixing sleeve body 51, and the two ends of the through hole 54 are respectively connected to annular cavity 52 and annular cavity 53.

[0019] Specifically, the fixed sleeve body 51 and the front end connecting sleeve 4 form a surrounding cavity, and the first annular cavity 52 is used to attract the front end of the pipe to be fitted, and the second annular cavity 53 is used to establish a low-pressure zone.

[0020] The adsorption and fixing assembly 7 includes a mounting sleeve 71, a piston plate 72, an adjusting rod 73, and a conduit 74. The mounting sleeve 71 is fixed to the front of the mounting cover 1. The piston plate 72 is movably sleeved in the mounting sleeve 71. The adjusting rod 73 is threaded onto the end of the mounting sleeve 71, and the inner end of the adjusting rod 73 is fixedly connected to the piston plate 72. One end of the conduit 74 is fixedly connected to the outside of the mounting sleeve 71, and the other end of the conduit 74 passes through the fixing sleeve body 51 and communicates with the annular cavity 53.

[0021] An auxiliary sealing ring is fitted on the outer side of the piston plate 72, which moves with the piston plate 72 to form a piston effect and ensure effective air suction. The threaded adjusting rod 73 can move telescopically when it rotates in a spiral, thus controlling the movement of the piston plate 72.

[0022] The sealing cover 6 includes a cover plate and a rubber ring. The rubber ring is fixed to the side of the cover plate and is sleeved in the ring cavity 52.

[0023] By connecting the rubber ring to the annular cavity 52, the front connecting sleeve 4, which is not used for assembly, is sealed. Furthermore, when the adsorption and fixing component 7 is suctioned, the adsorption and fixing of the sealing cover 6 is further strengthened to maintain a stable seal without the need for additional operations.

[0024] Among them, the inner wall of the rear connecting sleeve 3 is nested with an elastic sealing ring 11, the front of the mounting cover 2 is provided with an assembly ring cavity 10, the inside of the assembly ring cavity 10 is fitted with an elastic sealing ring 8, and the mounting cover 1 is threaded into the assembly ring cavity 10.

[0025] The elastic sealing ring 11 expands and fills the internally connected pipes, completing the wrapping, clamping, fixing, and sealing process. The elastic sealing ring 8 expands and fills the internally, strengthening the seal on the assembly ring cavity 10.

[0026] The mounting cover 2 has a composite sealing control component 9 fixedly installed on its front side. The composite sealing control component 9 controls the airflow and expansion of the elastic sealing ring 11 and the elastic sealing ring 8. The composite sealing control component 9 includes a mounting sleeve 91, a piston plate 92, an adjusting rod 93, and a conduit 94. The mounting sleeve 91 is fixedly installed on the front side of the mounting cover 2. The front side of the mounting cover 2 has a connecting cavity. The mounting sleeve 91 is connected to the elastic sealing ring 8 through the connecting cavity. The conduit 94 is fixedly connected to the outer side of the mounting sleeve 91. The other end of the conduit 94 is fixedly sleeved in the rear connecting sleeve 3. The mounting sleeve 91 is connected to the elastic sealing ring 11 through the conduit 94. The piston plate 92 is movably sleeved in the mounting sleeve 91. The adjusting rod 93 is threadedly sleeved at the end of the mounting sleeve 91, and the inner end of the adjusting rod 93 is fixedly connected to the piston plate 92.

[0027] The extension and retraction action is achieved by rotating the threaded adjusting rod 93, which causes the piston plate 92 to rotate forward and squeeze the filling fluid. The outer side of the piston plate 92 is also fitted with an auxiliary sealing ring to maintain dynamic sealing and prevent leakage.

[0028] The working principle and usage process of this utility model are as follows: During assembly, firstly, the mounting cover 1 is spirally assembled along the mounting ring cavity 10 on the front of the mounting cover 2. Then, the suction end pipe of the suction device is sleeved inside the rear connecting sleeve 3. The composite sealing control component 9 is rotated. As the adjusting rod 2 93 rotates spirally, it drives the piston plate 2 92 to move in the mounting sleeve 2 91, compressing the internal fluid and increasing the hydraulic pressure. On the one hand, the fluid is filled and expanded inside the elastic sealing ring 8 through the connecting cavity. On the other hand, the fluid is introduced into the elastic sealing ring 2 11 through the conduit 2 94, causing it to expand. The expanded elastic sealing ring 1 8 seals between the mounting cover 1 and the mounting cover 2 2. The expanded elastic sealing ring 2 11 wraps around and fixes the suction pipe end of the sleeved suction device. The suction line used is selected according to the specifications of the suction line. The corresponding front connecting sleeve 4 on the front of the mounting cover 1 is selected, and the sealing cover 6 on the front of the corresponding front connecting sleeve 4 is removed. The suction line is fitted onto the outside of the front connecting sleeve 4, and then fitted into the annular cavity 52 along the mounting fixing sleeve 5 on its outside. At the same time, the fitting end of the suction line abuts against and covers the through hole 54. The adjusting rod 73 in the suction fixing assembly 7 is rotated to drive the piston plate 72 to draw gas from the mounting sleeve 71. Air is drawn from the annular cavity 53 through the connecting conduit 74, so that a low-pressure area is formed inside the annular cavity 53. The fitting end of the suction line is adsorbed and fixed in the annular cavity 52 by the through hole 54, and the quick fixation is completed, thereby completing the connection of the two ends of the connector.
