[0009] Preferably, the fence assembly also includes two second fences, the two second fences are arranged on the left and right sides of the upper side of the base, the two second fences pass through the first support plate and the second support plate upward and are slidably connected thereto, the two second fences are respectively provided with second limiting railings on the tops, and the protruding height of the two second fences on the second support plate is consistent with the protruding height of the first fence on the first support plate.

[0010] Preferably, the fence assembly also includes two third fences, and the two third fences are arranged on the front and rear sides of the upper side of the second support plate. The tops of the two third fences are respectively provided with third limiting rails. Under the push of the electric telescopic rod, the two third limiting rails can be abutted against the bottom of the placement rack.

[0011] Preferably, the protruding height of the third fence on the second support plate is consistent with the protruding height of the second fence on the second support plate.

[0012] Preferably, there are four connecting rods, which are respectively vertically arranged at the bottom of the placement rack, the upper ends of the connecting rods are fixedly connected to the bottom of the placement rack, the lower ends of the connecting rods respectively pass through the first support plate and the second support plate, and are fixed on the upper side of the base, and the connecting rods are respectively slidably connected to the first support plate and the second support plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a medical trolley with a lifting structure, which controls the extension and retraction of the electric telescopic rod through an external control device, so that the two support plates can be controlled to perform lifting movements at the same time. When the electric telescopic rod is extended, the first support plate moves up, and the second support plate is driven to move up synchronously through the connecting column. Since the first fence and the second fence are fixed on the base, they remain stationary during the rising process of the two support plates until the top of the third limit rail abuts against the bottom of the placement frame. At this time, the first limit rail abuts against the side surface of the first support plate, and the front and rear sides of the side surface of the first support plate are in an open state, and the second limit rail abuts against the side surface of the second support plate, and the left and right sides of the side surface of the second support plate are in an open state, which is convenient for taking articles.

[0015] On the contrary, when the telescopic rod is in a retracted state, the fence assembly is used to protect the sides of the first support plate and the second support plate to ensure that the items will not slip out of the support plates during mobile transportation. At the same time, this lifting structure has a simple design, easy adjustment and high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In the embodiment proposed in the present application, a medical trolley with a lifting structure comprises a base 1, a universal wheel 11 is arranged on the lower side of the base 1, a first support plate 2 is arranged on the upper side of the base 1, an electric telescopic rod 3 is vertically arranged in the base 1 corresponding to the lower side of the first support plate 2, the electric telescopic rod 3 is electrically connected to an external control device, support columns 4 are vertically arranged at the four corners of the upper side edge of the first support plate 2, a second support plate 5 is horizontally arranged on the top of the four support columns 4, a fence assembly 6 is movably arranged outside the first support plate 2 and the second support plate 5, a placement frame 7 is horizontally arranged above the second support plate 5, a push frame 71 is arranged on the right side of the placement frame 7, and the bottom of the placement frame 7 is fixedly connected to the upper side of the base 1 through a connecting rod 72;

[0022] The fence assembly 6 is used to protect the upper side surfaces of the first support plate 2 and the second support plate 5 to ensure that the items will not slip out of the support plates during mobile transportation. The electric telescopic rod 3 is used to lift and lower the two support plates to facilitate the taking and placing of items. The design is simple, the adjustment is convenient, and the practicability is high. The external control equipment and electrical connection method here belong to the existing technology and will not be described here.

[0023] In another embodiment, see Figure 1-3The fence assembly 6 includes two first fences 61, which are arranged on the front and rear sides of the upper side of the base 1. The two first fences 61 pass upward through the first support plate 2 and are slidably connected thereto. The tops of the two first fences 61 are respectively provided with first limiting rails 62, and the two first limiting rails 62 abut against the bottom of the second support plate 5; when the electric telescopic rod 3 is extended, the first support plate 2 slides upward on the first fences 61 until it abuts against the first limiting rails 62. At this time, the front and rear sides of the first support plate 2 are in an open state, which is convenient for taking and placing items on the upper side of the first support plate 2.

[0024] At the same time, the fence assembly 6 also includes two second fences 63, which are arranged on the left and right sides of the upper side of the base 1. The two second fences 63 pass through the first support plate 2 and the second support plate 5 upward and are slidably connected thereto. Second limiting rails 64 are respectively provided on the tops of the two second fences 63. The protruding height of the two second fences 63 on the second support plate 5 is consistent with the protruding height of the first fence 61 on the first support plate 2; when the electric telescopic rod 3 is extended, the second support plate 5, driven by the support column 4, slides upward on the second fence 63 along with the first support plate 2 to the upper side of the second support plate 5 and abuts against the second limiting rail 64. At this time, the left and right sides of the second support plate 5 are in an open state, which is convenient for taking and placing items on the upper side of the second support plate 5.

[0025] At the same time, the fence assembly 6 also includes two third fences 65, which are arranged on the front and rear sides of the upper side of the second support plate 5, and the tops of the two third fences 65 are respectively provided with third limiting rails 66. Under the push of the electric telescopic rod 3, the two third limiting rails 66 can abut against the bottom of the placement rack 7, and the protruding height of the third fence 65 on the second support plate 5 is consistent with the protruding height of the second fence 63 on the second support plate 5;

[0026] The first fence 61, the second fence 63 and the third fence 65 can simultaneously protect the outer periphery of the upper side of the first support plate 2 and the second support plate 5 when the electric telescopic rod 3 is in the retracted state, ensuring that the objects will not slip out of the support plates during movement and transportation.

[0027] In another embodiment, see Figure 1-3 There are four connecting rods 72, which are respectively vertically arranged at the bottom of the placement frame 7.
