[0022] Please refer to Figure 1 and Figure 2 , the high-pressure syringe tube clamping structure 1 of the embodiment of the present utility model includes a chassis 11, a rotating shaft 12, a turntable 13, a clamping wheel 14, a lifting device 15, a first clamping block 16, and a second clamping block 17. The turntable 13, the chassis 11, and the rotating shaft 12 are arranged in sequence from top to bottom. The rotating shaft 12 is rotatably arranged on the chassis 11, the turntable 13 is fixedly connected to the rotating shaft 12, a plurality of the clamping wheels 14 are arranged along the edge of the turntable 13, the first clamping block 16 is arranged at the upper left of the chassis 11, the second clamping block 17 is arranged at the upper right of the chassis 11, the lifting device 15 is used to drive the second clamping block 17 to move up and down, and both the first clamping block 16 and the second clamping block 17 are used to clamp the infusion tube.

[0023] In the above embodiment, the structure realizes the automatic loading and fixing of the infusion tube through modular components, reducing manual operation. The core lies in the coordinated work of the chassis 11, the rotating shaft 12, the turntable 13, the clamping wheels 14, the lifting device 15, and the first and second clamping blocks 17. The rotating shaft 12 is rotatably installed on the chassis 11. The rotating shaft 12 can rotate under the restraint of the chassis 11, while the chassis 11 itself remains stationary. The rotating shaft 12 and the turntable 13 are synchronously moved through a fixed connection, that is, when the rotating shaft 12 rotates, the turntable 13 will also rotate accordingly. A plurality of clamping wheels 14 are evenly distributed on the edge of the turntable 13 for guiding and initially fixing the infusion tube. The first clamping block 16 is fixedly arranged at the upper left of the chassis 11 as the starting point for loading the infusion tube. The second clamping block 17 is installed at the upper right of the chassis 11 through the lifting device 15. During loading, the user only needs to place one end of the infusion tube into the first clamping block 16, and then guide it through between the clamping wheels 14 until the other end touches the position of the second clamping block 17. At this time, start the lifting device 15 to lower the second clamping block 17 and firmly clamp the infusion tube to complete the initial fixing. Subsequently, the turntable 13 is rotated by an external drive to drive the clamping wheels 14 and the infusion tube therebetween to move clockwise or counterclockwise along the edge of the turntable 13. With the continuous rotation of the turntable 13, the infusion tube gradually penetrates into the interior of the chassis 11 under the guidance of the clamping wheels 14 until it is completely clamped and locked in a predetermined position, realizing the whole process of automatic loading. This design effectively solves the cumbersome and inconvenient traditional manual loading of the infusion tube and improves the operation efficiency.

[0024] Please refer to Figure 2 , Figure 3 and Figure 4 , in another embodiment, the rotating shaft 12 is provided with an annular slideway 121, and the chassis 11 is provided with an annular chute 111 matching the annular slideway 121.

[0025] In the above embodiment, an annular slideway 121 is designed inside the rotating shaft 12, and the chassis 11 is correspondingly provided with an annular chute 111 that precisely matches it. When the rotating shaft 12 is installed on the chassis 11, the annular slideway 121 and the annular chute 111 are mutually engaged to form a stable rotational connection.

[0026] Please refer to Figure 2 and Figure 5 , in another embodiment, the clamping wheel 14 includes a first wheel 141 and a second wheel 142. An annular groove 1411 is provided on the side of the first wheel 141. One second wheel 142 is provided between the two first wheels 141, and the distance between the two first wheels 141 and the second wheel 142 is equal.

[0027] In the above embodiment, the side of the first wheel 141 is designed with an annular groove 1411, which is designed to provide stable guidance and clamping for the infusion tube, ensuring that the infusion tube can maintain a stable position during the rotation process and is not easy to slip or shift. Between the two first wheels 141, a second wheel 142 is equidistantly arranged. Such a layout not only enhances the overall structural strength of the clamping wheel 14 unit, but also enables the infusion tube to be supported more evenly and stably when passing through. The equidistant arrangement between the first wheel 141 and the second wheel 142 helps to maintain the balance of the infusion tube during the rotation process and reduce the friction and wear caused by uneven force.

[0028] See also Figure 2 as well as Figure 6 In another embodiment, the first clamping block 16 includes a first retaining block 161 and a cover plate 162, the first retaining block 161 is provided with a first clamping groove 1611 for clamping the infusion tube, and the cover plate 162 covers the first clamping groove 1611.

[0029] In the above embodiment, the first retaining block 161 is provided with a first slot 1611 specifically used to clamp the infusion tube, and the cover plate 162 is designed to cover the first slot 1611 to further fix the infusion tube by physical closure to prevent it from accidentally falling off or moving during operation.

[0030] See also Figure 2 as well as Figure 7 In another embodiment, the second clamping block 17 includes a second retaining block 171 and an embedding block 172, and the second retaining block 171 is provided with a second clamping groove 1711 for clamping the infusion tube.

[0031] In the above embodiment, the second retaining block 171 is provided with a second slot 1711, which is specially designed to hold the infusion tube, ensuring that the infusion tube can be stably placed. When the infusion tube is placed in the second slot 1711, the lifting device 15 is started to drive the embedding block 172 to move downward until it is completely embedded in the machine, achieving a close fit with the second retaining block 171. This process completes the physical closure and fixation of the infusion tube, effectively preventing the infusion tube from accidentally moving or falling off during rotation or transportation.

[0032] See also Figure 3 as well as Figure 7 In another embodiment, the chassis 11 is provided with a notch 112 , and the embedded block 172 is extended to be provided with a blocking rod 1721 for abutting against the notch 112 .

[0033] In the above embodiment, during the downward movement of the embedding block 172, the blocking rod 1721 provided on its extended part will precisely align with and abut against the notch 112 on the chassis 11. When the embedding block 172 is completely embedded in the machine, the blocking rod 1721 is in close contact with the notch 112, forming a physical block and limit, thereby enhancing the connection stability between the second clamping block 17 and the chassis 11 and preventing any accidental movement of the infusion tube during the fixing process.

[0034] Please refer to Figure 2 and Figure 7 , in another embodiment, the lifting device 15 includes a lifting motor 151 and a limiting block 152. The second retaining block 171 is connected to the lifting motor 151. The limiting block 152 is provided with a limiting groove 1521, and the limiting groove 1521 fits with the second retaining block 171.

[0035] In the above embodiment, the lifting motor 151 is directly connected to the second retaining block 171 and is responsible for driving it to move up and down to complete the fixing of the infusion tube. At the same time, the limiting block 152 is designed with a limiting groove 1521, and the shape and size of the limiting groove 1521 fit with the convex block of the second retaining block 171, ensuring that the second retaining block 171 can move smoothly along a predetermined path during the lifting process, thereby ensuring the accuracy and stability of the infusion tube fixing.

[0036] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the technical solution scope of the present invention, can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiment based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
