[0023] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a one-button unlocking device for an extension arm IV stand includes a first extension arm 5, a second extension arm 6, a one-button unlocking component, an IV stand 2, and a mounting base 9. One end of the second extension arm 6 is connected to the mounting base 9, and the other end is connected to the first extension arm 5 via a joint adjustment knob 7. The one-button unlocking component is connected to the upper surface of the other end of the first extension arm 5, and the IV stand 2 is connected to the one-button unlocking component. The mounting base 9 is connected to the second extension arm 6 via a joint pivot 10. A hook 1 is connected to the upper end of the IV stand 2.

[0026] Specifically, the one-click unlocking component includes a housing 3, inside which a clamping ring 12 is installed. The clamping ring 12 is connected to one side of the inside of the housing 3 by two first screws 16. A columnar pre-embedded nut 15 is rotatably connected inside the housing 3. The head of the quick-tightening handle 4 is rotatably connected to the outer wall of the columnar pre-embedded nut 15, and the head of the quick-tightening handle 4 is in sliding contact with the outer wall of the clamping ring 12. By rotating the quick-tightening handle 4, the clamping ring 12 is clamped and released, thereby allowing the infusion stand 2 to be raised and lowered.

[0027] Specifically, the clamping ring 12 has two ends connected to adjusting screws 13; the inner wall of the clamping ring 12 clamps the outer wall of the infusion stand 2. The tightness of the clamping ring 12 can be adjusted by adjusting the screws 13, which can meet the clamping requirements and also achieve clamping and unlocking with minimal force.

[0028] Specifically, the outer wall of the clamping ring 12 that contacts the head of the quick-tensioning handle 4 is an arc surface, and a pipe clamp gasket 14 is connected thereto. The pipe clamp gasket 14 has wear-resistant and lubricating properties, which prevents direct friction between the quick-tensioning handle 4 and the clamping ring 12 and improves its service life.

[0029] Specifically, the inner wall of the clamping ring 12 is toothed, making it more secure when clamping the IV stand 2.

[0030] Specifically, the upper end face of the cover 3 is connected to the top cover 18 by two second screws 17.

[0031] Specifically, the clamping ring 12 has two mounting holes on the side near the quick-tightening handle 4, which are fixed to the first extension arm 5 by the first screw 16. The other side is a movable side, forming an elastic arm. The clamping ring 12 has a through hole for installing a plug adjusting screw 13. The mating surface between the clamping ring 12 and the pipe clamp gasket 14 is an arc surface. The head of the quick-tightening handle 4 has an opening that is not concentric with the outer circle, forming an eccentric wheel. When clamping, the elastic arm is compressed inward due to the action of the eccentric wheel, thus clamping. When unlocking, the elastic arm returns to its original shape due to its own elasticity, thus unlocking, making operation convenient. A columnar pre-embedded nut 15 is in the eccentric wheel hole at the head of the quick-tightening handle 4, serving as the rotation center of the quick-tightening handle. The pipe clamp gasket 14 is arc-shaped, with one arc surface attached to the quick-tightening handle 4 and the other arc surface tightly attached to the clamping ring 12. It has wear-resistant and lubricating properties, avoiding direct friction between the quick-tightening handle and the clamping ring, and improving its service life.

[0032] This extendable arm IV stand features a one-button unlocking device. Rotating the quick-release handle 4 causes the clamping ring 12 to clamp and release, thereby adjusting the height of the IV stand 2. The clamping ring 12, with its internal arc-shaped toothed structure, provides uniform clamping force and a large contact area, preventing damage to the IV stand. The tightness can be adjusted by inserting the adjusting screw 13, achieving a labor-saving effect. Locking and unlocking the IV pole requires only one action, eliminating the need for multiple rotations and improving operational efficiency. This avoids potential obstacles during secondary use due to differences in strength among users, thus enhancing the user experience.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
