DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0032] The specific implementation of the present application is described in detail below in combination with specific examples.

[0033] As Figures 1-4 shown, the infusion medicine suspension device provided by one embodiment of the present application includes a hanging bearing plate 1 and a device bearing base 9, the lower side of the hanging bearing plate 1 and the upper side of the device bearing base 9 are respectively fixed with a height adjustable column 4 and a main body stabilizing column 6, and the height adjustable column 4 and the main body stabilizing column 6 are slidingly connected, the lower side outer ring of the hanging bearing plate 1 is further provided with a hanging hook 2, and the hanging hook 2 can be circumferentially and uniformly distributed with multiple ones, facilitating the hanging of the infusion bag / bottle. Further including:

[0034] A transmission box 12 is fixed to the upper part of the main body stabilizing column 6, the transmission box 12 is respectively provided with a transmission shaft 13 and a linkage shaft 19, a worm 21 is fixed to the transmission shaft 13 on the inner side of the transmission box 12, a worm wheel 20 is fixed to the linkage shaft 19 on the inner side of the transmission box 12, the worm wheel 20 and the worm 21 are meshingly connected, and a gear 22 is fixed to the linkage shaft 19 on the inner side of the main body stabilizing column 6;

[0036] The adjustable height column 4 is also equipped with an adjustment component for adjusting the sliding resistance between itself and the main stabilizing column 6.

[0037] In this embodiment of the invention, a conventional infusion suspension structure is formed by the suspension bearing plate 1, the device bearing base 9, the adjustable height column 4, the main stabilizing column 6, and the hook 2. A transmission box 12 and other transmission components are further added. When the rack 17 meshes with the gear 22, rotating the transmission shaft 13 drives the worm gear 20 to rotate via the worm 21, which in turn drives the coaxial gear 22 to rotate, thus raising and lowering the rack 17 along with the adjustable height column 4. The worm 21 and worm gear 20 have a self-locking effect, automatically maintaining stability after adjustment. Furthermore, if rapid adjustment of the adjustable height column 4 is required, the rack 17 can be moved away from the gear 22 using the control component. This allows for quick adjustment of the adjustable height column 4, followed by fine-tuning by rotating the transmission shaft 13, which is convenient and quick. The adjustment component can adjust the sliding resistance between the adjustable height column 4 and the main stabilizing column 6, preventing the adjustable height column 4 from rapidly descending after the rack 17 separates from the gear 22, thus improving its reliability.

[0038] In summary, this invention ensures the convenience, stability, and reliability of height adjustment for infusion equipment through the worm gear self-locking mechanism and the fine-tuning and rapid adjustment function of the adjustable height column 4.

[0044] As shown in Figures 1-4 , 7-9, as a preferred embodiment of the present application, the upper side of the height-adjustable column 4 is provided with a first recess 3, the main body stabilizing column 6 is provided with a avoiding opening 7 corresponding to the first recess 3, the inner side of the height-adjustable column 4 is provided with a second cavity 35, the rack 17 slides into the second cavity 35, the control assembly includes a spring 33 and an unlocking handle 5, both ends of the rack 17 are provided with a notch 34, the notch 34 is fixed with the spring 33, the other end of the spring 33 is fixedly connected with the end of the second cavity 35 away from the rack 17, the first recess 3 is further provided with the unlocking handle 5, the unlocking handle 5 adopts a U-shaped structure, both branches of the unlocking handle 5 slide into the second cavity 35 and are fixedly connected with the rack 17. When there is no external force, the rack 17 and the gear 22 are in meshing connection state under the elastic force of the spring 33; pulling the unlocking handle 5 can make the rack 17 and the gear 22 separate, so as to release the meshing connection state, which is convenient for manual operation of the height-adjustable column 4 to quickly lift.

[0045] As shown in Figures 1-6As shown, as a preferred embodiment of the present application, the inner side of the height-adjustable column 4 is further provided with a first cavity 27, the adjusting assembly comprises a support block 23, an outer tube 24, an inner rod 25, a damping wheel 26, an axle 28, an abutting plate 29, a threaded cylinder 30, a wheel carrier 31 and a screw rod 32, the support block 23 is fixed in the first cavity 27, the outer tube 24 is fixed through the support block 23, the upper end of the outer tube 24 extends from the top of the suspension bearing plate 1, and the outer tube 24 is fixedly connected with the suspension bearing plate 1, the inner side of the outer tube 24 is rotatably installed with the inner rod 25, the upper end of the inner rod 25 is fixed with a knob, the lower end of the inner rod 25 is fixed with the screw rod 32, the lower end of the outer tube 24 is fixed with the wheel carrier 31, the wheel carrier 31 is rotatably installed with the damping wheel 26 through the axle 28, the damping wheel 26 abuts against the inner wall of the main body stabilizing column 6, and the wheel carrier 31 is further slidably provided with the threaded cylinder 30, and the inner rod 25 is threadedly connected with the threaded cylinder 30, the lower end of the threaded cylinder 30 is fixed with the abutting plate 29 which abuts against the damping wheel 26. The support block 23 can stably support the outer tube 24 and other components, rotating the knob to drive the inner rod 25 to rotate, so as to drive the screw rod 32 to rotate, because the screw rod 32 is threadedly connected with the threaded cylinder 30, the threaded cylinder 30 can be driven to ascend and descend, so as to adjust the abutting tightness of the abutting plate 29 and the damping wheel 26, further control the resistance of the damping wheel 26 relative to the main body stabilizing column 6, complete the sliding resistance adjustment between the height-adjustable column 4 and the main body stabilizing column 6, and avoid the phenomenon that the height-adjustable column 4 rapidly descends after the rack 17 and the gear 22 are separated, thereby improving the reliability.

[0046] The outer edge of the damping wheel 26 is covered with a polyurethane rubber layer, and the Shore hardness thereof is 70±5 HA.

[0048] If the height needs to be quickly adjusted, the rack 17 can be pulled away from the gear 22 through the unlocking handle 5 in the control assembly, so as to quickly adjust the height of the height-adjustable column 4, and then the transmission shaft 13 is finely adjusted to the required position.

[0049] In addition, the adjusting assembly adjusts the relative position between the inner rod 25 and the threaded barrel 30 through the knob, changes the pressure of the abutting plate 29 on the damping wheel 26, and adjusts the sliding resistance, so as to prevent the height-adjustable column 4 from rapidly descending after the rack 17 is separated from the gear 22.
