[0029] like Figures 1 to 8 As shown, an L-shaped folding trolley provided by an embodiment of the utility model includes a base 1 and a folding unit, wherein the folding unit includes a vertical plate 2 and a column 3, two vertical plates 2 are symmetrically arranged on the base 1, a column 3 is rotatably installed in the middle of each of the two vertical plates 2, a slot 4 is provided on each of the two columns 3, the two vertical plates 2 are connected to each other on one side close to the edge of the base 1 by a horizontal plate 5, the first threaded rod 6 is passed through the column 3 and the vertical plate 2 on one side close to the horizontal plate 5 to position the column 3, and a plurality of layer plates 7 are evenly installed on the two vertical plates 2 from the bottom to the top.

[0030] Specifically, the base 1 is a bearing structure for supporting the columns 3 and the layer plates 7. A plurality of universal wheels 8 are evenly installed at the bottom end of the base 1. The base 1 is driven to move by the rolling of the universal wheels 8, so that the base 1 can move freely. A brake is provided on each universal wheel 8. The universal wheel 8 is positioned by the brake, so that the universal wheel 8 can be positioned, so that the base 1 can be stably positioned. The two vertical plates 2 are symmetrically arranged at the edge of the base 1. The two vertical plates 2 are connected by a horizontal plate 5. The connection of the two vertical plates 2 by the horizontal plate 5 ensures the stability of the installation of the vertical plates 2. The vertical plates 2 are provided with a card slot 4, the middle part of the column 3 is rotatably installed in the slot 4 of the vertical plate 2, the first threaded rod 6 penetrates the vertical plate 2 and is threadedly connected in the column 3, so as to perform positioning operation on the column 3, and the two side walls of the slot 4 position the column 3, and a positioning point can be set at the top of the first threaded rod 6 (that is, one or more first threaded rods 6 are set at the top of the first threaded rod 6 to perform multi-point positioning on the column 3) to perform multi-point positioning on the column 3 to ensure the stability of the installation of the column 3, and the top side walls of the two columns 3 are connected by a connecting plate 9 to further ensure the stability of the installation of the column 3, and the two The tops of the columns 3 are connected by a supporting plate 10, and the supporting plate 10 and the two columns 3 are connected by a third threaded rod. The bottom end of the supporting plate 10 between the two columns 3 is provided with a pull-out keyboard tray 11. The pull-out keyboard tray 11 is a pull-out plate structure that can be pulled out between the two columns 3. A keyboard or other items can be placed on the pull-out keyboard tray 11. By adjusting the position of the third threaded rod on the column 3, the height of the supporting plate 10 on the column 3 can be adjusted. The size of the space required for placing the items is adjusted, that is, the height of the support plate 10 is adjusted according to the size and height of the items to adapt to the height and size of the items. When the column 3 needs to be folded and contracted, the medical staff unscrews the third threaded rod out of the column 3 and the support plate 10, leaving a third threaded rod symmetrical to each other on each of the two columns 3, so that the support plate 10 can rotate around the third threaded rod as the center. The medical staff then unscrews each first threaded rod 6 out of the column 3 and the vertical plate 2, so that the column 3 can rotate around the middle thereof, so that the column 3 and the base 1 are parallel to each other (such as Figure 6 As shown), the column 3 can be folded to reduce the space occupied by the trolley during transportation; in the prior art, since the trolley cannot be folded, the space occupied by the trolley during transportation or storage is large, which makes the transportation of the trolley inconvenient and easily causes damage to the trolley; in the present embodiment, when the trolley needs to be folded for transportation, the first threaded rod 6 is unscrewed from the column 3 and the vertical plate 2, and then the column 3 is folded, thereby realizing the folding and contraction of the base 1 and the column 3, which can reduce the volume of the trolley and facilitate transportation.

[0031] Preferably, a plurality of slide grooves 12 are evenly provided on the two uprights 3 from the bottom to the top, and the mutually symmetrical slide grooves 12 on the two uprights 3 are at the same height. Two sliders 13 are symmetrically installed on both sides of each of the layer plates 7, that is, a slider 13 is provided at each of the two middle parts and the two ends close to the side of the cross plate of a layer plate 7, and four sliders 13 are provided on a layer plate 7, and each of the sliders 13 is slidably installed in the corresponding slide groove 12; a threaded groove is provided on the slider 13 on the side of each layer plate 7 close to the cross plate 5, and a second threaded rod 14 passes through the threaded grooves of the uprights 3 and the sliders 13 and is threadedly connected.

[0032] Specifically, the slider 13 is a cylindrical structure. When the column 3 needs to be folded, before each first threaded rod 6 is screwed out of the column 3 and the slider 13, the medical staff screws the second threaded rod 14 out of the column 3 and the slider 13, and then pushes the slider 13 away from the end of the second threaded rod 14 to slide out of the slide groove 12, leaving only the slider 13 connected to the second threaded rod 14 in the slide groove 12, so that the layer plate 7 can rotate around the slider 13 connected to the second threaded rod 14, so that the layer plate 7 can rotate, which provides convenience for the folding of the column 3. When the column 3 is not folded, the slider 13 is slidably installed in the slide groove 12, and then the second threaded rod 14 is tightened, so that the second threaded rod 14 positions the slider 13 on the column 3, so that the installation of the layer plate 7 is more stable. The penetration position of the second threaded rod 14 set on the column 3 can be set to multiple (such as Figure 5 As shown), the position of the shelf 7 on the column 3 can also be adjusted, so that the spacing between the shelf plates 7 can adapt to the size of the items (that is, when the items are large, the shelf plates 7 are arranged away from the side of the cross plate 5, so that more of the shelf plates 7 extend out of the column 3, and there is a certain misalignment between the shelf plates 7, so that larger items can be placed on the extended shelf plates 7), thereby providing practical performance, and the number of shelf plates 7 can be selected according to demand.

[0033] Preferably, a bra cup fixing seat 15 is provided on one side of the horizontal plate 5 on one of the columns 3, and a support rod fixing seat 16 is provided on the other side of the horizontal plate 5 on the other column 3; a hanger 17 is movably provided on the bra cup fixing seat 15; and a display robot arm support rod 18 is provided on the support rod fixing seat 16.

[0034] Specifically, the detection cup can be placed on the bracket 17, and the position of the bracket 17 can be adjusted on the column 3. The bracket 17 is slidably installed on the detection cup fixing seat 15. By adjusting the movable clamping sleeve connected between the bracket 17 and the column 3 (that is, the movable clamping structure for installing the bracket 17 on the column 3), the display body can be installed on the display mechanical arm support rod 18, so that the display body can be adjusted in all directions and in height.

[0035] In another embodiment provided by the utility model, a limit plate 19 is rotatably installed on the top of each of the two vertical plates 2, and two threaded grooves 20 are sequentially arranged on the side wall of the column 3 on the side close to the horizontal plate 5 from the bottom end to the top end, and a through hole 21 is arranged on the limit plate 19, and a fourth threaded rod 22 is arranged in the through hole 21, and the fourth threaded rod 22 is threadedly connected to the two threaded grooves 20.

[0036] Specifically, the limit plate 19 is rotatably arranged on the vertical plate 2, and the limit plate 19 has two states: a state in which the limit plate 19 is perpendicular to the vertical plate 2 and a state in which the limit plate 19 is parallel to the vertical plate 2, corresponding to the folding state of the trolley and the normal use state of the trolley; (1) when the trolley is in the folded state, that is, when the vertical plate 2 and the base 1 are in a mutually parallel position, the limit plate 19 and the vertical plate 2 are in a vertical state (such as Figure 8 As shown in the figure), the fourth threaded rod 22 on the limiting plate 19 is threadedly connected with the threaded groove 20 located on the side close to the horizontal plate 5, so that the limiting plate 19 and the fourth threaded rod 22 can position the vertical plate 2, so that the vertical plate 2 will not rotate when it is in the folded state, making the folded state of the trolley more stable and more convenient for transportation of the trolley; (2) when the trolley is in normal use, that is, when the vertical plate 2 and the base 1 are in a mutually perpendicular position, the limiting plate 19 and the vertical plate 2 are in a parallel state (as shown in the figure). Figure 7 As shown), and the limit plate 19 is located at the top of the vertical plate 2, the fourth threaded rod 22 on the limit plate 19 is threadedly connected with the threaded groove 20 located on the side away from the horizontal plate 5, that is, the fourth threaded rod 22 is threadedly connected with the threaded groove 20 on the side of the top of the column 3, so that the limit plate 19 and the fourth threaded rod 22 perform positioning operations on the vertical plate 2, so that the vertical plate 2 will not rotate when it is in normal use, making the trolley more stable when used, and because the limit plate 19 and the fourth threaded rod 22 position the vertical plate 2, the use of the first threaded rod 6 to position the vertical plate 2 can be cancelled at this time, and the first threaded rod 6 can also be installed to position the vertical plate 2.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
