Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a medical tray rack trolley which can be raised and lowered quickly. Background Art

[0002] Medical tray rack carts are commonly used medical equipment in hospitals, mainly used to load medical equipment and medicines. They have the advantages of high transportation efficiency, wide application scenarios, and easy cleaning. However, existing medical tray rack carts are generally integrated structures or sleeve rod top screw lifting structures, which are not convenient for adjusting the height and are not convenient for fast switching between different medical scenes and medical personnel. Therefore, a medical tray rack cart that can be quickly lifted and lowered is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a medical tray rack trolley with a new lifting method, which can quickly adjust the height of the medical tray and facilitate switching between different medical care scenes and medical personnel.

[0004] A medical tray rack trolley capable of being raised and lowered quickly comprises:

[0005] The vehicle body is installed with four silent universal wheels, the first-level lifting rod is inserted into the vehicle body upright pole, and the first-level lifting locking knob is used to tighten and fix the lifting height of the first-level lifting rod.

[0006] The first-level lifting rod connects the upper lifting arm and the second-level lifting lower lifting arm, and uses two second-level lifting tension springs to balance the pallet loading pressure. The second and third-level lifting connectors are fixed above the second-level lifting arm, and the mother-and-child rivets are installed on the first-level lifting rod and the second and third-level lifting connectors.

[0007] The upper lifting arm and the lower lifting arm of the third lifting are fixed above the second and third lifting connectors, and two third lifting tension springs are used to balance the pressure of the pallet load, and the third lifting locking knob is used to tighten and fix the lifting height of the third lifting arm. The rivets that can hang the tension springs and the third lifting locking knob are installed on the second and third lifting connectors.

[0008] A pallet rack is fixed above the three-stage lifting arm, and the mother-and-child rivets are installed on the pallet rack, on which the medical pallet is placed.

[0009] There is a three-level lifting mechanism between the vehicle body and the pallet rack.

[0010] The first-stage lifting adopts a sleeve rod and top screw lifting structure, that is, the first-stage lifting rod is inserted into the vehicle body vertical rod, and the top screw is used to fix the height of the first-stage lifting rod.

[0011] The second-stage lifting adopts a parallelogram lifting structure, using two lifting arms, a first-stage lifting rod, and second- and third-stage lifting connectors to form a parallelogram. It uses the instability of the parallelogram for lifting and uses two tension springs to balance the pressure of the pallet load.

[0012] The third-level lift also uses a parallelogram lift structure, but in the opposite direction of the second-level lift. Through this two-pole lift reverse coordination method, the center of gravity of the pallet remains unchanged in the horizontal direction.

[0013] The three-stage lift uses two lifting arms, second- and third-stage lifting connectors, and a pallet rack to form a parallelogram. Two tension springs are used to balance the pressure of the pallet load, and the knob screws are tightened to increase the friction to lock the angle of the three-stage lift arm to prevent the lift arm from sliding down due to excessive pallet loads.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. It has the ability to quickly adjust the height. By using a parallelogram lifting mechanism, the height of the medical tray can be adjusted by directly pressing down or lifting the tray rack upward, which is convenient for medical personnel of different heights and different usage habits to quickly switch between them.

[0016] 2. The tray can be placed at a lower or higher height. By adjusting all three-level lifts to the lowest position, the tray is 53 cm above the ground. By adjusting all three-level lifts to the highest position, the tray is 127 cm above the ground. The height limit of the tray placement is larger than that of existing medical tray rack carts, making it suitable for use in a wider range of medical care scenarios.

[0017] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Some implementation modes of the present application are described in detail below in conjunction with the accompanying drawings, but they are not intended to limit the present invention.

[0029] As attached Figure 1 , 2 As shown, the present application provides a medical pallet rack trolley that can be quickly lifted and lowered, including a vehicle body 201 equipped with four silent universal wheels 202, a first-level lifting rod 101 inserted into the vehicle body vertical rod, a first-level lifting locking knob 203 is used to tighten and fix the height of the first-level lifting rod, the first-level lifting rod connects the upper lifting arm 104 and the second-level lifting lower lifting arm 105, and two second-level lifting tension springs 107 are used to balance the pressure of the pallet load, a second- and third-level lifting connecting piece 102 is fixed above the second-level lifting arm, an upper lifting arm 104 and a third-level lifting lower lifting arm 106 are fixed above the second- and third-level lifting connecting piece, and two third-level lifting tension springs 108 are used to balance the pressure of the pallet load, a third-level lifting locking knob 111 is used to tighten and fix the angle of the third-level lifting arm, a pallet rack 103 is fixed above the third-level lifting arm, and a medical pallet 301 is placed on the pallet rack.

[0030] The method of using the present invention comprises the following specific steps:

[0031] S1: Drag any part of the cart body 201 or the tray rack 103, except for the medical tray 301 (the tray is only placed on the tray rack without a fixed connection), and move the tray rack cart to realize the transportation of medical devices and drugs;

[0032] S2: In the initial state, the first-level lifting rod 101 is inserted into the vertical pole of the vehicle body 201. After loosening the first-level lifting locking knob 203, the first-level lifting rod 101 can be lifted up and down. After adjusting to a suitable height, the first-level lifting locking knob 203 needs to be tightened to fix it;

[0033] S3: When the three-stage lifting locking knob 111 is tightened, the tray rack 103 is pressed downward to lower the second stage lifting, and the tray rack is lifted upward to raise the second stage lifting;

[0034] S4: When the three-level lifting locking knob 111 is loosened, the three-level lifting and the second-level lifting of the pallet rack are pressed downward to descend synchronously, and the three-level lifting and the second-level lifting of the pallet rack are lifted upward to rise synchronously. After adjusting to the appropriate height, the three-level lifting locking knob 111 needs to be tightened to fix it.
