Description

Technical Field

[0001] The utility model relates to the technical field of medical carts, in particular to a universal wheel for a medical cart. Background Art

[0002] Medical trolleys refer to medical equipment for ward protection and transportation. They are suitable for large hospitals, health clinics, pharmacies, psychiatric hospitals and various daily use rotating trolleys. They can greatly reduce the operating burden of caregivers. In terms of product classification, medical trolleys are divided into luxury, medium and ordinary ones.

[0003] Publication No. CN219505789U discloses a medical cart universal wheel with brake, which can press the rotating shaft by stepping on the brake plate, and hinder the rotation of the rotating shaft through the friction between the brake plate and the rotating shaft, so that the first roller and the second roller stop rolling, and the medical cart can be braked in time. However, during use, when encountering a slope at the stairs, carrying an ambulance up and down, and other places with height differences, the patient on the medical cart may move his body due to shaking, causing secondary damage to the injured part. For this reason, we propose a medical cart universal wheel. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a medical cart universal wheel, comprising a fixed frame 1, the top of the fixed frame 1 is fixedly connected with two sets of fixed bases 2, the top of the fixed base 2 is fixedly installed with a hydraulic buffer rod 3, the outer periphery of the hydraulic buffer rod 3 is fixedly connected with a return spring 4 at the top of the fixed frame 1, the top of the return spring 4 is fixed to the bottom end of the mounting seat 9, and the top of the hydraulic buffer rod 3 is fixed to the inside of the connecting base 6, and the connecting base 6 is fixed to the bottom end of the mounting seat 9;

[0025] The top of the mounting seat 9 is fixedly connected with a rotating groove 10 , the center of the rotating groove 10 is rotatably connected with a connecting frame 11 , the interior of the connecting frame 11 is clamped with a clamping piece 12 , and the top of the clamping piece 12 is fixedly connected with a connecting seat 13 .

[0026] When in use, the vertical sliding buffer structure allows the device to shrink the buffer to reduce the shaking caused by moving the medical cart when encountering a bumpy road section with a height difference during movement, thereby effectively improving the patient's comfort when lying down and reducing the damage to the patient caused by the bumps of the medical cart.

The fixed frame 1 and the mounting seat 9 are limited by the limiting slide groove 7 and the limiting slide rod 8 to limit the range of vertical sliding, and the medical cart is driven to move by the roller 5. The medical cart is connected to the connecting frame 11 by the clamping piece 12 to connect the medical cart at the top of the connecting seat 13 with the rotating groove 10, so that the medical cart can achieve all-round steering through the rotating connection between the rotating groove 10 and the connecting frame 11.
