Technical Field
[0001] The invention relates to the technical field of medical vehicles, in particular to a leveling device for a treatment chair of a medical vehicle. Background Art
[0002] A medical vehicle is a vehicle used for medical rescue or medical services. It is a mobile treatment unit. In emergency situations, especially for the rescue of emergency patients in long distances or remote areas, when patients are transferred to the hospital or cannot be transferred to the hospital, they receive first aid, rescue and other medical services on the treatment bed or treatment chair in the vehicle, which plays a vital role in the treatment of patients.
[0003] At present, after the medical vehicle arrives at the rescue area, the patient needs to be transferred to the vehicle for treatment. However, in remote areas, especially in the wild, rural or mountainous areas, due to the terrain, the roads are rugged and the terrain is undulating, which causes the medical vehicle to be parked in a tilted state, resulting in the patient being unable to sit steadily on the treatment chair, thereby increasing the difficulty of treatment and even being unable to receive treatment in time, which will delay the treatment time and affect the treatment effect. Therefore, there is an urgent need for a treatment vehicle that can adjust the balance base of the treatment chair under different terrain conditions to solve the above problems.

[0028] The chair leg support seat is composed of a support slider 14 and a support tube 4. The support slider 14 is arranged in the lifting slide groove 3, and the support tube 4 is arranged on the support slider 14. The support tube 4 is used to place the chair leg.
[0029] The base 1 and the hinged platform 5 are both designed as a cubic structure, the lifting plate 2 is designed as a trapezoidal structure, and the inner end of the lifting plate 2 is hinged to the four sides of the hinged platform 5 respectively, and the outer end thereof is hinged to the lifting mechanism.
[0030] The support tube 4 is designed as a cup-shaped structure with a small bottom and a wide top, which can prevent the chair legs on the inclined surface from lifting up and driving the corresponding left and right chair legs to lift up, thereby preventing the support tube 4 from getting stuck and unable to lift up.
[0031] Limiting grooves 10 are provided on both sides of the lifting slide 3, and protrusions matching the limiting grooves 10 are provided on the supporting slider 14. When the supporting slider 14 moves along the lifting slide 3, the protrusions are embedded in the limiting grooves 10 to prevent the slider from falling off the lifting slide 3.
[0032] The lifting mechanism is composed of a motor, a bidirectional screw 12, two sliding seats and two lifting rods 9. The motor is arranged on one side of the mounting groove 8, and the bidirectional screw 12 is rotatably arranged in the mounting groove 8, and one end of the bidirectional screw 12 is connected to the output end of the motor, and the other end is movably connected to the base 1, and the bidirectional screw 12 can be driven to rotate by the motor; the sliding seats are respectively threadedly connected to the two ends of the bidirectional screw 12, and the lifting rod 9 is movably connected in an X-shaped cross, and one end of the lifting rod 9 is hinged to the sliding seat, and the other end is hinged to the lifting plate 2. When the bidirectional screw 12 rotates, the sliding seat can be made to move toward or relative to each other, thereby driving the support frame 9 to lift or descend, thereby achieving the purpose of controlling the lifting and lowering of the lifting plate 2.
[0033] The sliding seat is composed of a lifting slider 11 and a rotating block 13. The lifting slider 11 is arranged as an H-shaped structure.

The lifting slider 11 is axially provided with a threaded hole penetrating the lifting slider 11. The lifting slider 11 is connected to a bidirectional screw rod 12 through the threaded hole. The rotating block 13 is movably arranged in the middle of the lifting slider 11, and the side length of the rotating block 13 is smaller than the width of the installation groove 8 to avoid the rotating block 13 being stuck with the installation groove 8 when rotating. The rotating block 13 is hinged to the lifting rod 9. When the lifting slider 11 slides, it can drive the lifting rod 9 to lift or descend.
[0034] Working principle of the present invention:
[0035] When the treatment vehicle is parked on an uneven terrain, the treatment chair is high in the front and low in the back. Fig. 9 As shown, at this time, the motor of the lifting mechanism corresponding to the inclined area is started, driving the bidirectional screw rod to rotate, so that the lifting slider moves towards each other, and at this time, the lifting rod hinged with the rotating block is lifted upward to lift the lifting plate. Since the lifting plate is hinged with the hinged platform, the tail of the lifting plate rises in an arc when it is lifted. At this time, under the action of the rotating block, the lifting rod will rotate inward with the rise of the lifting plate, and the sliding block will move upward along the lifting slide groove under the action of the rise of the lifting plate, driving the support tube to rise, until the chair foot is lifted to the corresponding height, the motor is turned off to stop the lifting rod, and the buckle is buckled into the corresponding fixing hook to fix the support tube, thereby achieving the purpose of lifting the chair foot at the inclined position;
[0036] Since the chair legs are fixedly connected, when the chair legs at the inclined position are lifted, the chair legs on the left and right sides will be lifted together and separated from their corresponding support tubes. At this time, the motor of the left lifting mechanism is started, and the lifting plate on the left is lifted through the support frame to lift the support tube on the lifting plate until it rests against the chair legs on the left. Then the motor is turned off, and the buckle on the support tube is buckled into the corresponding fixing hook to fix the left chair leg. Repeat the above process to lift and fix the right chair leg. Finally, the support tube at the lifted chair leg is buckled into the corresponding fixing hook through the buckle to complete the process of changing the treatment chair from a tilted state to a stable state.
[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that several improvements and modifications may be made without departing from the spirit or essential features of the present invention, and these improvements and modifications shall also be regarded as the scope of protection of the present invention.
