Description

Technical Field

[0001] The invention relates to the technical field of nursing vehicles, and in particular to a folding auxiliary table plate and a nursing vehicle composed of the folding auxiliary table plate. Background Art

[0002] Nursing carts are usually used to load medical machinery and medicines. If a nursing cart does not have an auxiliary table, its loading area may be relatively limited and cannot meet the needs of different patients. Especially in narrow aisles, larger nursing carts may be inconvenient to move, reducing the practicality of the nursing cart. Moreover, if a nursing cart does not have a foldable auxiliary table, it may take up more space when not in use, and the loading area cannot be quickly and conveniently expanded when needed.

[0003] Therefore, a foldable auxiliary table for a nursing vehicle with a variable loading area and convenient operation is proposed. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to address the shortcomings of the prior art, such as limited loading area and a large space occupied by the table top, and to provide a nursing cart composed of a foldable auxiliary table. When the auxiliary table is unfolded, the loading area can be increased. The folded auxiliary table can be close to the side wall of the nursing cart, saving space to the greatest extent and improving the flexibility of the nursing cart in narrow spaces.

[0005] Technical solution: The folding auxiliary table described in the present invention includes a table top and a folding device for driving the table top to unfold and close;

[0006] The folding device includes two support frames and a fixed box. The fixed end of the support frame is hinged to the fixed box. The working end of the support frame is fixedly connected with a table top. When the support frame rotates around the hinge, the table top is driven to unfold or close.

[0007] A rotating column is fixed in the axial direction inside the fixed box, and compression springs are respectively sleeved at both ends of the rotating column. The compression spring is limited by a limit block. A limit slot is provided on the box body of the fixed box, and the limit block is fixedly connected to the support frame through a connecting shaft; the connecting shaft is limited by the limit slot.

[0008] Furthermore, the limiting groove includes a first limiting groove located on the side of the fixed box and a second limiting groove located at the bottom of the fixed box, and the first limiting groove and the second limiting groove are connected; when the table top is unfolded, the connecting shaft is located in the first limiting groove; when the table top is closed, the connecting shaft is located in the second limiting groove.

[0009] Furthermore, the connecting shaft has an arc, and the end of the connecting shaft connected to the support frame is higher than the end of the connecting shaft connected to the fixing box. When the operator manually pulls up or presses down the auxiliary table, the arc can buffer the applied force; and due to the setting of the arc, when the table is in the unfolded state, the height of the table on the support frame can be higher than the height of the fixing box.

[0010] Furthermore, a fixing device is provided on the opposite side of the fixing box and the first limiting groove, and the fixing device can be fixed on any plane, so that the auxiliary platform can be conveniently fixed on any device, thereby increasing the loading area of ​​the device.

[0011] The present invention further provides a nursing vehicle, comprising a vehicle body, on the side of which is fixed a folding auxiliary table provided by the present invention.

[0012] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0013] (1) The utility model provides an auxiliary table that can be fixedly connected to the plane of any device through a folding mechanism, thereby increasing the loading area of ​​the device. At the same time, due to the design of the folding device, the auxiliary table can be folded or unfolded, and the space utilization is flexible;

[0014] (2) The utility model provides a nursing cart with an auxiliary table. In the unfolded state, when the loading area needs to be increased, the auxiliary table can be easily unfolded and firmly fixed by the improved limit block and compression spring to ensure smooth use. In the folded state, when it is not needed, the auxiliary table can be quickly folded back to one side of the nursing cart to save space;

[0015] (3) The folding device provided by the utility model, in which the connecting shaft, the first limit groove, the second limit groove, the compression spring and the limit block work together, the movement and reset are achieved by the compression spring, and the limit groove and the limit block are achieved. Therefore, the improved folding device makes the folding process smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this embodiment provides a folding auxiliary table, including a table top 2 and a folding device for driving the table top 2 to unfold and close.

[0025] The folding device includes two support frames 3 and a fixed box 4; a rotating column 9 is fixed in the axial direction inside the fixed box 4, and compression springs 5 ​​are respectively sleeved at both ends of the rotating column 9, and the compression spring 5 is limited by a limit block 6. A limit slot 8 is provided on the box body of the fixed box 7, and the limit block 6 is fixedly connected to the support frame 3 through a connecting shaft 7; the connecting shaft 7 is limited by the limit slot 8. The limit slot 8 includes a first limit slot located on the side of the fixed box 4 and a second limit slot located at the bottom of the fixed box 4, and the first limit slot and the second limit slot are connected; when the table 2 is unfolded, the connecting shaft 7 is located in the first limit slot; when the table 2 is closed, the connecting shaft 7 is located in the second limit slot. The connecting shaft 7 has an arc.

[0026] When the folding device needs to be fixed to an external object to increase the loading area of ​​the object, a fixing device is provided on the opposite side of the fixing box 4 and the first limiting groove. The fixing device can be fixed on any plane, such as one side of the nursing cart, to assist the nursing cart in increasing the loading area.
