The seat bottom frame 3 and the seat stretcher 4 are locked by the locking mechanism 5, so The locking mechanism described above is composed of a handle 315, a ring sleeve 314, a positioning lock 312 and a spring 313. When the medical staff pushes into the seat stretcher, the fixing plate 411 provided on the seat stretcher contacts the positioning lock, and under the action of the spring, the fixing plate 411 contacts the positioning lock. The positioning lock is retracted, and stops when the fixing plate 411 crosses the positioning lock and reaches the fixing plate 311 on the seat bottom frame. At this time, the positioning lock returns to the original position under the action of the spring to realize the locking of the seat stretcher 4 , In the locked state, the multifunctional transfer chair can perform sitting position transfer, lying position transfer and realize adjustment of different examination states.

As shown in Figure 1, Figure 2 and Figure 3, the seat bottom frame is composed of seat leg frame 31, seat seat frame 35, seat back frame 33 and armrest frame 32, forming a parallelogram mechanism, located at the bottom The gas spring 23 in the middle of the frame is rotatably connected to the seat support frame 2 and the seat leg frame 31. When it is necessary to transfer the sitting posture, the medical staff holds the handle 332 on the seat back frame 33 and touches the gas The spring control switch 334 can change the shape of the entire seat. Specifically, through the contraction of the gas spring 23, the seat leg frame 31 connected to one end of the gas spring is turned from the horizontal direction to the vertical direction, and is connected to the seat leg frame. The seat frame 35 and the armrest frame 32 are kept moving in parallel, the seat back frame 33 connected with the seat frame and the armrest frame is turned from the horizontal direction to the vertical direction, and the seat back frame 33 and the seat leg frame 31 are kept In parallel, when the seat back frame and the seat leg frame turn to the nearly vertical direction, the multifunctional transfer chair can be switched to the sitting posture state. At this time, the medical staff can push the horizontal handle 332 to transfer the sitting posture.

Further, when it is necessary to transfer the lying position, the medical staff holds the handle 331 on the seat back frame 33 and touches the gas spring control switch 333 to change the shape of the entire seat. long, the seat leg frame 31 connected to one end of the gas spring is turned from the vertical direction to the horizontal direction, and the seat seat frame 35 and the armrest frame 32 connected to the seat leg frame keep moving in parallel with the seat frame and the armrest frame The connected seat back frame 33 is turned from the vertical direction to the horizontal direction, the seat back frame 33 and the seat leg frame 31 are kept parallel, when the seat leg frame, seat seat frame, seat back frame and armrest frame are all in the horizontal direction When the direction is turned, the switching of the multifunctional transfer chair to the lying position is realized, and the medical staff can push the horizontal handle 331 to transfer the lying position.

Preferably, in order to facilitate the transfer of sitting and lying positions by medical staff, the seat back frame 33 of the present invention is fixedly provided with push handles 331 and 332 at a certain angle. The handle 332 is in a proper pushing position, and the handle 331 is at a proper pushing position when transferring from the lying position.

In order to realize that the multifunctional transfer chair can meet various inclined examination positions, as shown in Figures 1 and 3, two symmetrically arranged gas springs 22 are rotatably connected at both ends to the bottom frame 1 and the seat support frame 2. , The seat support frame and the gas spring form a rotating mechanism. When the patient is in a lying position, the medical staff holds the handle 332 on the seat back rod 33 and triggers the gas spring control switch 334. The gas spring extends or contracts, and is connected to the gas spring. The seat support frame on the seat rotates, and drives the seat frame connected to the seat support frame to rotate counterclockwise or clockwise, so that the inclination of the seat surface can be realized, so as to facilitate the inspection of various body positions. Springs improve the stability, vibration resistance and flexibility of the multifunctional transfer chair.

The multifunctional transfer chair of the present invention can also realize the transfer function of a stretcher.
