[0017] like Figure 1 As shown, the lower surface of the movable bottom plate 1 is fixedly connected with a universal wheel 10, and the upper right sides of the two vertical plates 2 located on the right side of the movable bottom plate 1 are fixedly connected with a push rod 17; By means of the push rod 17, medical staff can easily realize free rotation through the multiple universal wheels 10, which is convenient for medical staff to perform steering operations in different areas such as hospital corridors and wards. At the same time, the multiple universal wheels 10 are also equipped with reliable braking devices. When the cart reaches the designated position, the medical staff can firmly fix the cart in place by stepping on the brake pedal to prevent it from sliding accidentally.
[0018] like Figure 1 , Figure 2 and Figure 4 As shown, an assembled medical cart frame is provided, including a movable bottom plate 1, the left and right sides of the upper surface of the movable bottom plate 1 are symmetrically fixedly connected with vertical plates 2, the opposite sides of two adjacent vertical plates 2 are provided with adjustment vertical grooves 3, a movable plate 4 is arranged between two adjacent vertical plates 2, the opposite sides of two movable plates 4 located in the same horizontal plane are commonly fixedly connected with a placement plate 5, the front and rear surfaces of multiple movable plates 4 are fixedly connected with sliders 6, the multiple sliders 6 are respectively slidably connected to the inside of multiple adjustment vertical grooves 3, the inner side walls of multiple adjustment vertical grooves 3 are provided with multiple positioning circular holes 7, the insides of multiple sliders 6 are slidably connected with sliding plates 8, the multiple sliding plates 8 and the sides close to the multiple adjustment vertical grooves 3 are fixedly connected with plug-in columns 9, and the ends of multiple plug-in columns 9 and away from the multiple sliding plates 8 are respectively extended to the inside of multiple positioning circular holes 7; The device consists of a movable bottom plate 1 and a plurality of vertical plates 2. Adjustment vertical grooves 3 are provided on the outer sides of the plurality of vertical plates 2. A movable plate 4 is provided between adjacent vertical plates 2. A placement plate 5 is connected between the movable plates 4. Sliders 6 are provided on the front and rear surfaces of the movable plate 4. The sliders 6 are slidably connected with the adjustment vertical grooves 3. The height of the placement plate 5 can be fixed by inserting a plug-in column 9 into a positioning circular hole 7. At the same time, the height positions of the movable plate 4 and the placement plate 5 can be adjusted by sliding the slide 6 in the adjustment vertical groove 3 and inserting the plug-in column 9 into different positioning circular holes 7, so that medical staff can continue to place the placement plate 5 according to actual needs, thereby further increasing the storage space of the device and improving the flexibility and practicality of the device.
[0019] like Figure 1 , Figure 2 and Figure 4As shown, a control cavity 11 is integrally formed inside the plurality of movable plates 4, and a sliding plate 12 is symmetrically slidably connected inside the control cavity 11, and the opposite sides of the two sliding plates 12 are respectively fixedly connected with the opposite sides of the two adjacent sliding plates 8 by a connecting rod 13, and the opposite sides of the interiors of the two control cavities 11 located in the same horizontal plane are provided with a through-type toggle groove 14, and the plurality of sliding plates 12 and one side close to the plurality of toggle grooves 14 are fixedly connected with a toggle plate 15, and the plurality of toggle plates 15 respectively pass through the plurality of toggle grooves 14, and the plurality of sliding plates 12 are respectively fixedly connected with the internal front surface and the internal rear surface of the plurality of control cavities 11 by a plurality of reset springs 16; When the two toggle plates 15 on the left and right sides of the placement plate 5 are toggled at the same time, the toggle plates 15 drive the sliding plate 12 to slide in the control chamber 11, compressing the reset spring 16. The sliding plate 12 drives the sliding plate 8 to move through the connecting rod 13, so that the plug-in column 9 is disengaged from the positioning circular hole 7. At this time, the two movable plates 4 can slide in the adjustment vertical groove 3. After moving to a suitable height, the toggle plates 15 are released, and the reset spring 16 rebounds to push the sliding plate 12 to reset, thereby reinserting the plug-in column 9 into the positioning circular hole 7 of the corresponding height, thereby quickly completing the adjustment of the height of the placement plate 5, thereby improving the convenience and efficiency of the device.
[0020] like Figure 1 As shown, the outer side walls of the plurality of vertical plates 2 are each provided with a plurality of hooks 23; The multiple hooks 23 further enhance the storage function and the use flexibility of the assembled medical cart frame, making it convenient to hang some commonly used medical supplies, such as infusion bags, stethoscopes, blood pressure cuffs and other items.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the upper parts of the two adjacent vertical adjustment slots 3 are both slidably connected with a stopper 19, the front and rear parts of the two stoppers 19 are integrally formed with a sliding cavity 20, the interior of the sliding cavity 20 is slidably connected with a movable plate 21, and the opposite sides of the two adjacent movable plates 21 are fixedly connected with plug-in columns 22, and the ends of the multiple plug-in columns 22 and away from the multiple movable plates 21 extend to the interiors of the multiple positioning circular holes 7 above respectively; Two baffle bars 19 are fixed at the top of multiple adjustment vertical slots 3 by plugging multiple plug-in columns 22 into the highest positioning circular holes 7. When the placement plate 5 rises to a certain height and approaches the two baffle bars 19, the baffle bars 19 can prevent the placement plate 5 from continuing to move upward, preventing it from detaching from the adjustment vertical slot 3 and preventing it from accidentally detaching, thereby ensuring the safety and stability of the cart frame when in use and avoiding items from falling or equipment damage due to the detachment of the placement plate 5.

At the same time, the setting of the limit frame 30 ensures the stability and reliability of the structure. When the rotating handle 25 is not operated, the stopper 19 can be firmly fixed to prevent accidental loosening or falling off, thereby ensuring the normal use of the trolley frame and the safety of items.
[0024] like Figure 4As shown, the upper surfaces of the two baffles 19 are symmetrically fixedly connected with connecting plates 31, and the lower surfaces of the multiple connecting plates 31 are respectively in contact with the upper surfaces of the multiple vertical plates 2; When installing the two baffles 19, a plurality of connecting plates 31 can provide certain positioning and guiding functions for the installation of the two baffles 19, preventing the two baffles 19 from continuing to slide downward inside the adjustment vertical groove 3, thereby facilitating the installation operation for medical staff and reducing errors and adjustment time during the installation process.
