Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a retractable infusion stand. Background Art

[0002] Infusion stands are common items in hospitals. In the ward, the infusion stands are set up next to the beds to hang infusion bottles. When giving infusions to patients in the hospital, most of the time the infusion bottles are hung upside down on the hooks of the infusion stands.

[0003] While tidying up the ward environment, we found that several infusion stands had serious deficiencies in storage. They occupied a large area and could not be better gathered and placed due to the irregular chassis. They were too high and would bump into other facilities in the ward. When idle, the large area occupied would cause the risk of patients tripping. Therefore, a retractable infusion stand was proposed. Utility Model Content

[0004] The utility model aims to provide a retractable infusion stand, which has the characteristics that the four legs of the infusion stand chassis can be made into movable devices, and the four legs form a square to facilitate stable landing, easy storage, and small footprint.

[0005] The utility model aims to provide a retractable infusion stand, comprising a sleeve, the outer wall of the sleeve being movably connected with four evenly distributed legs through a rotating shaft, the opposite sides of the four legs being movably connected with connecting rods through the rotating shaft, the lower end surface of the sleeve being provided with a support seat, the other ends of the four connecting rods being movably connected with the support seat through the rotating shaft, the upper end surface of the support seat being fixedly connected with a pull rod, the other end of the pull rod passes through the sleeve and is slidably connected to the sleeve and the other end is fixedly connected to an extension tube, the interior of the extension tube is fixedly connected with a support block, the other end of the support block is fixedly connected with a first spring, the other end of the first spring is fixedly connected with a limiting block, the other end of the limiting block passes through the extension tube and is slidably connected to the extension tube, a limiting hole is provided through the outer wall of the sleeve, and the limiting block is inserted into the interior of the limiting hole.

[0006] In order to provide the extension tube with rebound ability, as a preferred retractable infusion stand of the utility model, the lower end surface of the extension tube is fixedly connected to a second spring sleeved on the outer wall of the pull rod, and the other end of the second spring is fixedly connected to the bottom end of the sleeve.

[0007] In order to facilitate the hanging of the infusion bottle, as a preferred embodiment of the retractable infusion stand of the present invention, the upper end surface of the extension tube is threadedly connected to a support rod, and the outer wall of the support rod is fixedly connected to a plurality of evenly distributed hooks.

[0008] In order to enable the extension tube to telescopically move, as a preferred embodiment of the retractable infusion stand of the present invention, the outer wall of the extension tube is slidably connected to the inner wall of the sleeve.

[0009] In order to facilitate and stably support the four legs, as a preferred embodiment of the retractable infusion stand of the present invention, the opposite sides of the four legs are fixedly connected with a fixing plate.

[0010] In order to facilitate the movement of the four legs, as a preferred embodiment of the retractable infusion stand of the present invention, pulleys are installed on the opposite sides of the four legs.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model manually presses the limit block, and the limit block squeezes the second spring and presses the extension tube to move downward, so that the limit block enters the interior of the limit hole through the sleeve. When the extension tube moves downward, it squeezes the first spring to contract and pushes the pull rod to move downward. When the pull rod moves downward, the four connecting rods drive the matching legs to move relatively, so that the lower end surfaces of the four fixed plates abut against the ground, thereby achieving the purpose of making the four legs of the infusion stand chassis into movable devices and forming the four legs into a square so as to be stable on the ground, easy to store, and small in footprint.
