[0027] Embodiment: a lifting structure based on medical mobile trolley, like Figures 1-4 and Figure 6As shown, including the mounting plate 1, trolley frame 2, rear wheel 3, sleeve 4, front wheel 5, mounting base 7, stator 8, rotor 9, rotating cylinder 10, screw rod 11 and top plate 12, the trolley frame 2 is provided with a whole, the trolley frame 2 is inclined to the rear, a rear wheel 3 is rotatably arranged on the left and right sides of the bottom of the trolley frame 2, the rear wheel 3 is used to assist the trolley frame 2 to move, and a mounting plate 1 is slidably arranged on the trolley frame 2, the mounting plate 1 is a support platform for carrying each lifting component, and the mounting plate 1 can slide in the upward and downward directions along the trolley frame 2, so as to adjust the position of the bed support for subsequent operation, the mounting plate 1 is provided with a sleeve 4 on the bottom left and right, and a front wheel 5 is slidably arranged in each sleeve 4, the front wheel 5 cooperates with the rear wheel 3 to assist the movement of the whole trolley, the mounting base 7 is fixedly arranged on the top left and right of the mounting plate 1, the stator 8 is arranged on the mounting base 7, and the rotor 9 is rotatably connected to the same side of the stator 8, the rotating cylinder 10 is arranged in the rotor 9, the rotating cylinder 10 is provided with a helical protrusion on the inner wall of the shaft hole, and a longitudinal screw rod 11 is threadedly arranged in the shaft hole, the top plate 12 is arranged at the top end of the screw rod 11, and the screw rod 11 moves linearly under the action of the thread to drive the corresponding top plate 12 to move up and down.

[0028] In order to solve the problem of lifting the bed body in the prior art, specifically, the mobile trolley adopts an electric drive design, and realizes rotary motion through the interaction between the stator 8 and the rotor 9. When the trolley device is powered on, the rotor 9 starts to rotate under the magnetic field of the stator 8 after being powered on, and drives the connected rotating cylinder 10 to rotate synchronously. Since the rotating cylinder 10 is provided with a helical protrusion on the inner wall of the shaft hole, the screw rod 11 placed therein produces screw operation under the action of the thread, thereby realizing the upward lifting movement of the screw rod 11, quickly contacting and lifting the bed body to a suitable height. Thereby, the working efficiency and operation performance of the trolley are effectively improved, the risk of operation failure is reduced, and safer and better medical services are provided for patients.

[0029] More attention is paid to the fact that the structure ingeniously reduces the size of the traditional screw motor, thereby further reducing the need for additional connecting parts, and significantly reducing noise during lifting, thereby improving the comfort of the medical environment. Therefore, the whole scheme has the advantages of simple structure, stable connection, convenient installation and easy maintenance, and is suitable for the medical environment required for lifting the bed body.

[0030] As Figure 5As shown, it also includes the connecting plate 13, sliding frame 14 and the clamping plate 15, the connecting plate 13 is arranged between the top of the two side top plates 12, the connecting plate 13 is used for bearing connection, the sliding frame 14 is symmetrically arranged on the top of the connecting plate 13, the sliding frame 14 can slide in the upward and downward direction, the clamping plate 15 used for bearing the support bed body is also arranged between the two sliding frames 14, the clamping plate 15 is used as the carrier mainly in contact with the bed body support, and the front end of the clamping plate 15 is provided with a protrusion, an inclined surface inclined downward is formed on the protrusion end, which is suitable for fitting the top bed body to support stably, thereby effectively cooperating with the medical staff to operate, and then triggering the sliding operation to cooperate with the trend of the inclined surface to quickly support and fit the bed body, so as to facilitate the subsequent lifting operation.

[0031] As shown in Figure 5 It also includes the spring 17, the spring 17 is arranged between the clamping plate 15 and the two side sliding frames 14, and the spring 17 can play a buffering role for the clamping plate 15.

[0032] As shown in Figure 5 It also includes the baffle 16, the baffle 16 is arranged on the top rear side of the clamping plate 15, which is used to limit the rear side position of the bed body support placed on the clamping plate 15, so as to avoid the bed body from deviating.

[0033] As shown in Figure 5 It also includes the damper 18, the damper 18 is arranged between the front and rear sides of the bottom of the sliding frame 14 and the connecting plate 13, and the damper 18 is used to absorb vibration to ensure the stability during lifting.

[0034] As shown in Figure 6 It also includes the hydraulic cylinder 19, the hydraulic cylinder 19 is arranged on the front wheel 5 with the telescopic end upward, the telescopic end of the hydraulic cylinder 19 is connected with the mounting plate 1, which is used to drive the telescopic operation of the front wheel 5 and ensure the stable support of the front wheel 5 with the ground.

[0035] As shown in Figure 2 It also includes the horizontal plate 20 and the threaded rod 21, the horizontal plate 20 is arranged on the trolley frame 2, the threaded rod 21 is screwedly arranged on the horizontal plate 20, the bottom end of the threaded rod 21 is rotatably connected with the mounting plate 1, and rotating the threaded rod 21 can adjust the position of the mounting plate 1.

[0036] As shown in Figure 7 It also includes the electric push rod 22, the clamping rod 23 and the clamping block 24, a group of left and right symmetric electric push rods 22 is installed on the lower side of the trolley frame 2, the clamping rod 23 is arranged on the telescopic end of the electric push rod 22, and the clamping block 24 matched with the clamping rod 23 on the same side is arranged on the same side of the two rear wheels 3 in the circumferential direction, so as to fix the position of the rear wheel 3 and avoid displacement during lifting.

[0037] In use, the medical staff first need to place the trolley under the bed to be adjusted in height. Through the coordinated work of the front wheels 5 and the rear wheels 3, it is ensured that the trolley can be moved smoothly and positioned accurately. After the trolley is in place, the threaded rod 21 is first rotated, and the threaded rod 21 is lifted and lowered along the horizontal plate 20 by the action of the threads of the threaded rod 21, thereby driving the mounting plate 1 connected thereto to slide synchronously on the trolley frame 2 to adjust the position of the mounting plate 1 as a whole on the bottom of the bed. At the same time, the hydraulic cylinder 19 is started to keep the front wheels 5 in contact with the ground to support the bottom of the mounting plate 1. Then continue to operate until the top of the clamping plate 15 completely fits the bottom surface of the bed body, and the trolley as a whole is moved forward, so that the bottom surface of the bed body is tightly fitted with the clamping plate 15 and is guided by the inclined surface of the clamping plate 15 to gradually move to the middle of the clamping plate 15. Subsequently, the edge of the bed body is embedded in the clamping plate 15, and the baffle 16 limits the position of the bed body. Then, the electric push rod 22 is started to make the clamping rod 23 clamped into the corresponding clamping block 24 to fix the rear wheels 3 on both sides to prevent unnecessary movement. After the above steps are completed, the device is powered on, at this time the magnetic field generated by the stator 8 interacts with the rotor 9 to drive the rotor 9 to rotate, further driving the rotating cylinder 10 to rotate, so that the lead screw 11 moves linearly upward under the action of the internal threads. This causes the top plate 12, the connecting plate 13, the sliding frame 14 and the clamping plate 15 to rise together. When the clamping plate 15 presses against the bed body and is forced to press downward, the spring 17 deforms to buffer the action, the sliding frame 14 slides, the damper 18 absorbs the vibration to reduce the shaking during the lifting process, and the patient's comfort is ensured. Finally, under the continuous lifting action of the lead screw 11, the bed body is stably lifted.
