[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example: Figure 1 , 2 As shown in Figure 3, the operating room tray device of this embodiment includes a movable base 1, a lifting column 2, a fixed tray frame 3, and a pull-out tray frame 4. The lifting column 2 is vertically fixed to the upper end of the movable base 1, and the fixed tray frame 3 is fixed to the upper end of the lifting column 2. The two pull-out tray frames 4 and the fixed tray frame 3 are slidably assembled with the pull-out tray frame 4, and can be pulled out from both ends of the fixed tray frame 3 or pushed back into the fixed tray frame 3. A bedside fixing structure 5 is provided on one side of the fixed tray frame 3.

[0025] In this embodiment, the operating room tray device is moved to the side of the operating table during use. The height is adjusted using the lifting column 2, and then connected to the side of the operating table using the bedside fixing structure 5, providing stable support for the entire device. When in use, one or both pull-out tray frames 4 can be pulled out from the corresponding ends of the fixed tray frame 3, making the upper tray frame "larger." Multiple trays are then placed in the space between the unfolded fixed tray frame 3 and the pull-out tray frames 4. When not in use, the pull-out tray frames 4 can be completely pushed back, reducing the tray frame area for easy storage. The overall structural design is simple and reasonable, with good retraction and unfolding performance. It also effectively cooperates with the operating table to achieve stable use and prevent collisions, movement, or tipping.

[0026] As a preferred embodiment, the fixed tray holder 3 comprises a rectangular bottom plate 31 and two side plates 32 vertically arranged on the upper part of the two long sides of the bottom plate 31. The upper end of each side plate 32 is provided with a first sliding rail 321 along the length direction thereof, and the inner side of each side plate 32 is provided with a sliding groove 322 along the length direction thereof. One end of the upper part of one of the pull-out tray holders 4 is provided with a first sliding block 41 which is in sliding cooperation with the first sliding rail 321, and one end of the outer part of the other pull-out tray holder 4 is provided with a second sliding block 42 which is in sliding cooperation with the sliding groove 322. The one pull-out tray holder 4 is located on the inner side of the other pull-out tray holder 4, and the other end of each pull-out tray holder 4 is provided with a handle 43. The outer side of one side plate 32 is provided with the bedside fixed structure 5.

[0027] In the above embodiment, the other pull-out tray holder 4 is arranged on the inner side (the innermost side) of the fixed tray holder 3, and the sliding cooperation between the first sliding block 41 and the first sliding rail 321 serves as the connecting support, and then the pull-out tray holder 4 can be pulled out for use. The one pull-out tray holder 4 is arranged between the other pull-out tray holder 4 and the fixed tray holder 3, that is, the fixed tray holder 3 and the two pull-out tray holders 4 are designed in an inside-outside superposition structure, and the one pull-out tray holder 4 is connected and supported by the sliding cooperation between the sliding groove 322 and the second sliding block 42. The overall design is compact and ingenious, and the contraction and expansion are convenient.

[0028] As a preferred embodiment, the inner side of the bottom plate 31 is provided with two groups of passages which pass through the two ends thereof, and the lower part of the other end of each pull-out tray holder 4 is provided with a group of pull rods 44 which are adapted to the passages. The pull rod 44 is inserted into the corresponding passage.

[0029] In the above embodiment, the side of one end of each pull-out tray holder 4 which is close to the other pull-out tray holder 4 is connected and supported by the cooperation between the second sliding block 42 and the sliding groove 322 and the connection between the first sliding block 41 and the first sliding rail 321, and the other end is connected and supported by the connection between the pull rod 44 and the passage in the bottom plate 31, so that the pull-out tray holder 4 is stably supported during the pulling process and does not fall down or skew at the outer end during the pulling process.

[0030] It should be particularly noted that the two end ports of the passage are narrowed, and the end of the pull rod 44 which extends into the passage is provided with a limiting head which is slightly larger in volume, so that the pull rod 44 cannot be completely pulled out of the passage.

[0031] In the present embodiment, each group of passages is provided with two passages, and the support and connection are more stable.

[0032] In the embodiment, the side walls and the bottom of the pull-out tray frame 4 are hollow structures. The overall weight of the pull-out tray frame 4 is reduced, the load after pulling out is reduced, and the cost is also reduced.

[0033] In the embodiment, three trays are further included, and the three trays are respectively placed in the fixed tray frame 3 and the two pull-out tray frames 4 in the pulled-out state. The trays can be any trays that are suitable in length or width for the fixed tray frame 3 and the pull-out tray frame 4, and the use is flexible. When the fixed tray frame 3 and the pull-out tray frame 4 are stored, one tray can be placed above the fixed tray frame 3 (other trays can be stacked below), and after unfolding, one tray can be respectively placed in the fixed tray frame 3 and the two pull-out tray frames 4, and the use is flexible.

[0034] As a preferred embodiment, the bedside fixing structure 5 includes a lower support plate 51, an upper support plate 52, a movable clamping plate 53, and a tightening bolt 54. The lower support plate 51 and the upper support plate 52 are vertically spaced apart and are both horizontally fixed to one side of the fixed tray frame 3. The tightening bolt 54 is vertically arranged and is in threaded connection with a screw hole on the upper support plate 52. The upper end of the movable clamping plate 53 is connected.

[0035] In the embodiment, the edge of the operating bed is clamped between the lower support plate 51 and the movable clamping plate 53, and the tightening bolt 54 is rotated and pre-tightened, so that the device is stably combined with the edge of the operating bed and is prevented from being turned on one side.

[0036] In the embodiment, the bedside fixing structure 5 is provided with two groups and is spaced apart at the same height. The two groups of bedside fixing structures 5 are used at the same time, and the connection with the operating bed is more stable.

[0037] As a preferred embodiment, the lifting column 2 includes a hollow fixed column 21, a hollow movable column 22, a mandrel 23, a worm wheel 24, and a worm 25. The fixed column 21 is vertically fixed to the middle part of the upper end of the mobile base 1. The movable column 22 is vertically arranged, and the lower end thereof extends into the fixed column 21 and is in sliding connection with the fixed column 21. The mandrel 23 is vertically arranged, and the upper end thereof extends into the movable column 22, and the lower end thereof is in rotational connection with the lower end of the fixed column 21. The lower end of the movable column 22 is provided with a nut 221. The surface of the mandrel 23 is provided with a screw thread. The nut 221 is in threaded connection with the screw thread. The lower end of the mandrel 23 is connected with a short shaft that extends into the inside of the mobile base 1. The lower end of the short shaft is provided with the worm wheel 24. The mobile base 1 is horizontally rotatably provided with the worm 25. The worm 25 is in engagement with the worm wheel 24. One end of the worm 25 is connected with a handle 26 that extends to the side of the mobile base 1.

[0038] In the above embodiment, when lifting is needed, the operating handle 26 drives the worm 25 to rotate, the worm 25 drives the worm wheel 24 to rotate, and the mandrel 23 is rotated, since the movable column 22 is in sliding connection with the fixed column 21, the nut 221 cannot rotate, and can only move up and down relative to the mandrel 23, so that the hollow movable column 22 is lifted relative to the fixed column 21, the operation is relatively simple, and self-locking can be realized after lifting to position.

[0039] In the embodiment, the mobile base 1 comprises a base and a plurality of traveling wheels arranged at the lower end of the base.
