[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A portable dressing change cart comprises four bracket legs 1 and a handle frame 4, wherein three racks 2 are fixedly connected in the middle of the four bracket legs 1, the distance between each two adjacent racks 2 is 40 cm, and the racks 2 are made of stainless steel. Figure 1As shown, the shelf 2 is a concave stainless steel plate, which can not only hold a large number of medicines, but also protect the medicines on the edges around it, effectively preventing the medicines from shaking and falling from the surroundings during transportation.

[0021] In one or more embodiments of the present invention, a universal wheel 11 is installed at the lower end of each support leg 1, and the handle frame 4 is welded together with two adjacent support legs 1. It should be noted that the installation method and structure of the universal wheel 11 are the same as those of the existing dressing change cart, which is a common technology in the field, so it will not be described in detail here.

[0022] In one or more embodiments of the present invention, a fixing rod 14 is fixedly connected to the side wall of the uppermost shelf 2. Figure 1 As shown, the fixing rod 14 is an L-shaped rod. Such a design can facilitate the medical staff to push the device to walk and avoid the fixing rod 14 from colliding with the medical staff's legs.

[0023] In one or more embodiments of the utility model, the end of the fixing rod 14 away from the storage rack 2 is fixedly connected to the mechanism box 5, two lifting rods 7 are slidably connected in the mechanism box 5, the lower end of the lifting rod 7 is fixedly connected to the connecting rod 8, the lower end of the connecting rod 8 is fixedly connected to the fixing plate 3, and the lower end surface of the fixing plate 3 is frosted. Specifically, by frosting the lower surface of the fixing plate 3, the friction between the fixing plate 3 and the ground can be increased to improve the stability of its support.

[0024] In one or more embodiments of the present invention, a lifting mechanism for lifting the lifting rod 7 is installed in the mechanism box 5. The lower end of the lifting rod 7 slides through the inner bottom of the mechanism box 5, and the two lifting rods 7 are symmetrically arranged along the axis of the nut 13.

[0025] In one or more embodiments of the utility model, the lifting mechanism includes a threaded rod 9 rotatably connected to the mechanism box 5, a nut 13 is threadedly connected to the threaded rod 9, two lifting rods 7 are respectively fixedly connected to the two sides of the nut 13, and the threaded rod 9 controls the rotation of the nut 13 through the rotating mechanism. It should be noted that by providing two lifting rods 7, on the one hand, the nut 13 can be limited so that the nut 13 can only move vertically up and down, and on the other hand, it can also ensure that the nut 13 is more stable when moving vertically.

[0026] In one or more embodiments of the present invention, the rotating mechanism includes a rotating sleeve 6, a first bevel gear 10 and a second bevel gear 12, the first bevel gear 10 is fixedly connected to the upper end of the threaded rod 9, the rotating sleeve 6 is rotatably arranged on the push handle frame 4, and the rotating sleeve 6 is fixedly connected to the second bevel gear 12. It should be noted that, referring to Figure 1 and Figure 2The push handle frame 4 is welded by two inclined steel pipes and a horizontal steel pipe, wherein the two inclined steel pipes can be welded to the upper ends of the two bracket legs 1, and the horizontal steel pipe is welded between the two inclined steel pipes, and the rotating sleeve 6 is sleeved on the outside of the horizontal steel pipe and can rotate freely.

[0027] In the utility model, different types of medicines can be placed on different racks 2 according to needs, and the whole device can be pushed by pushing the push handle 4 to move, so as to transport the medicines to the designated place. After the transportation is completed, the second bevel gear 12 can be driven to rotate by twisting the rotating sleeve 6, and then the first bevel gear 10 can be driven to rotate, so that the threaded rod 9 can be rotated, and finally the nut 13 can move downward, and the nut 13 can push the fixed plate 3 downward through the lifting rod 7 and the connecting rod 8, so that the whole device can be supported by the fixed plate 3, and the contact area between the fixed plate 3 and the ground is greatly increased. At the same time, the friction between the lower surface of the fixed plate 3 and the ground is greatly increased after the frosting treatment, so that the whole device can be stable and immovable, and it will not slide easily even if a collision occurs, thereby preventing the medicines on the rack 2 from spilling.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
