Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a wheel pressure type high pressure injector for correcting wheel axle stress. Background Art

[0002] CN113855934A and zl2023220816483 respectively show a wheel-pressure high-pressure injector, both of which have the same technical problem. That is, when working, the pressure wheel at the bottom of the turntable maintains a high force with the tube-pressing base through the compressed infusion tube, while the pressure wheel at the top of the turntable is suspended in the air. The force applied upward by the tube-pressing base is ultimately provided by the rotating shaft of the turntable to provide an opposite force, so that the entire pressure wheel mechanism maintains a force balance. That is, the axis of the turntable not only provides the torque of the circular motion, but also provides a radial force pointing to the tube-pressing base. After a certain period of use, the rotating shaft will show obvious wear and axial deviation. Utility Model Content

[0013] like Figures 1 to 3 As shown, the wheel pressure type high-pressure injector for correcting wheel axle stress in the utility model comprises a pipeline pressurizing mechanism 10 arranged at the upper end of the body; a pipe pressing base 11 and a rotating disk 12 adapted to the pipe pressing base 11 are arranged at the lower part of the pipeline pressurizing mechanism 10; a plurality of pressing wheels and guide wheels are arranged on the rotating disk 12;

[0014] The tube pressing base 11 is in a circular shape and is arranged concentrically with the rotating shaft of the turntable 12; a slide groove 14 is provided at the upper end of the tube pressing base 11 and runs through it from top to bottom; a matching slider 13 is provided in the slide groove 14; a rotating shaft 15 is provided on the tube pressing base 11 above the slider 13, and the axis of the rotating shaft 15 is parallel to the rotating shaft of the turntable 12; a pressure block 16 is sleeved on the outer side of the rotating shaft 15, one end of the pressure block 16 rotates around the rotating shaft 15, and the other end extends freely; a rotary arm 17 is also extended upward from the end of the pressure block 16 that rotates around the rotating shaft 15; the pressure block 16 is used to make the slider 13 apply pressure to the pressing wheel of the turntable 12, or release the pressure of the slider 13 on the pressing wheel.

[0015] The swing arm 17 extends upward beyond the edge of the pipe pressing base 11 , and the pipeline pressurizing mechanism 10 is provided with a notch for the swing arm 17 to swing.

[0016] The working principle of the wheel pressure type high pressure injector for correcting wheel axle stress described in the utility model is as follows:

[0017] When the infusion tube is installed between the tube pressing base 11 and the rotating disk 12, the swing arm 17 causes the pressure block 16 to press down the slider 13. The slider 13 applies pressure to the pressing wheel of the rotating disk 12. At this time, the downward force of the slider 13 and the upward force fed back to the rotating disk 12 by the tube pressing base 11 through the infusion tube are basically offset, reducing the radial stress of the rotating shaft during operation.

[0018] When the infusion tube is removed from between the tube pressing base 11 and the turntable 12, the reverse swing arm 17 makes the pressure block 16 leave the slider 13, thereby releasing the pressure of the slider 13 on the turntable 12. Avoid applying unnecessary pressure to the rotating shaft of the turntable 12 during non-working hours.

[0019] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
