Technical Field

[0001] The invention relates to a switcher, in particular to a switcher for a helicopter which is convenient for being transported up and down by a flat car. Background Art

[0002] The transfer flatbed is a medical flatbed suitable for emergency and first aid patients. It not only can conveniently transfer patients, but also does not require the patient to be lifted off the stretcher after being moved to the examination table or bed. Instead, the stretcher poles can be withdrawn, reducing the pain of the patient when being lifted off the stretcher.

[0003] For patients who need emergency treatment by helicopter, medical staff will only use a flatbed cart to move the patient to the side of the helicopter, and then lift the flatbed cart into the helicopter for transportation. After being transported to the emergency area, medical staff will lift the flatbed cart and the patient off the helicopter. This lifting method can easily cause the patient to fall from the flatbed cart to the ground, causing great harm to the patient. In view of the above defects, it is necessary to design a switch for helicopters to facilitate the up and down transportation of flatbed carts. Summary of the Invention

The front and rear ends of the outer wall of the placement plate 2 are fixed with limiting mechanisms 6 that can control the placement plate 2 to fix its position after rotation.

[0024] The helicopter uses a switch that facilitates the up and down transportation of flatbed carts. First, the medical staff installs the base plate 1 in the helicopter. The medical staff first takes out the moving mechanism 4 from the base plate 1, and then rotates the placement plate 2, so that the linkage mechanism 3 drives the placement plate 2 to overlap with the ground. Synchronously, the moving mechanism 4 and the ground are perpendicular to each other. The medical staff then uses the limiting mechanism 6 to make the placement plate 2 fit with the ground and the overlapping state is fixed. The medical staff then moves the flatbed cart onto the placement plate 2, and then uses the driving mechanism 5 to make the placement plate 2 and the flatbed cart flush with the base plate 1, and then moves the flatbed cart onto the base plate 1, so as to safely move the patient into the helicopter.

[0027] The helicopter uses a switch that is convenient for carrying up and down the flat car. Before use, the base plate 1 is first firmly connected to the stepping area of the helicopter, and the mounting column 8 is facing the entrance of the helicopter. When in use, the medical staff first pulls the mounting column 8, so that the mounting column 8 drives the rotating plate 12 together with the slider 11 to move from right to left along the direction of the base plate 1. After the rotating plate 12 is completely moved out from the inside of the base plate 1, the medical staff then rotates the placement plate 2 counterclockwise so that the placement plate 2 is in contact with the ground, that is, the rotating plate 12 is perpendicular to the ground. The medical staff then screws the stud 16 into the rotating shaft 7 to constrain and fix the placement plate 2 to be aligned with the ground. The medical staff then turns on the forward rotation function of the motor 13, and the motor 13 drives the screw rod 14 to rotate forward. Through the threaded transmission of the screw rod 14 and the support column 9, the support column 9 drives the connecting column 10 Together with the placement plate 2 and the flatbed, the flatbed moves from bottom to top along the direction of the rotating plate 12 until the placement plate 2 and the base plate 1 are nearly flush. The medical staff can then easily push the flatbed from the placement plate 2 to the base plate 1, thereby enabling the flatbed and the patient to be safely moved into the helicopter. The medical staff can then store and restore the device. Similarly, when the medical staff needs to move the patient on the flatbed out of the helicopter, the device is unfolded in the same manner as above, and the placement plate 2 and the base plate 1 are flush. The flatbed is then pushed from the base plate 1 to the placement plate 2, and the reversing function of the motor 13 is turned on, thereby enabling the placement plate 2 and the flatbed to move from top to bottom along the direction of the rotating plate 12 until the placement plate 2 contacts the ground. The medical staff can then push the flatbed from the placement plate 2 to the ground. The motor 13 in this application is connected to the power lead on the helicopter. The motor 13 has forward and reverse rotation and self-locking functions.
