A turning device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the structure of a turning device according to an embodiment of the present invention. As shown in Figure 1, the turning device of the present embodiment comprises: L-shaped fixed part 101, L-shaped movable part 102, first motor 103 and second motor 104, wherein the horizontal arm of L-shaped fixed part 101 is provided with groove 105 And its vertical arm is provided with the first shaft hole 106; The horizontal arm of L-shaped movable part 102 is provided with the guide rail 108 that is fixedly connected with slide block 107 and its vertical arm is provided with the second shaft hole 109, and wherein, guide rail 108 and groove 105 is slidably connected and the first shaft hole 106 and the second shaft hole 109 are rotationally connected by a turning shaft 110 .

Further, the first motor 103 is connected to the horizontal arm of the L-shaped movable member 102 for driving the guide rail 108 to slide along the groove 105 .

Moreover, the second motor 104 is arranged on the L-shaped fixed part 101 and is used to drive the L-shaped movable part 102 to rotate around the turning axis 110 through a sprocket chain combination. In an embodiment, the first and second motors are stepping motors, but the present invention is not limited thereto.

In the embodiment, the horizontal arm of the L-shaped movable part 102 is provided with a round hole, and the first motor 103 is connected with the horizontal arm of the L-shaped movable part 102 through the ball screw 119 installed on the round hole.

In an embodiment, the vertical arm of the L-shaped fixture 101 is provided with a worm gear reducer 111, wherein the output shaft 112 of the worm gear reducer 111 is equipped with a first sprocket 113 and the turning shaft 110 is equipped with a second sprocket 114, The first sprocket 113 and the second sprocket 114 are connected with a chain 115 to form the sprocket chain combination, so that under the drive of the second motor 104 connected with the worm gear reducer 111, the L-shaped movable member 102 goes around The flip shaft 110 rotates.

As shown in FIG. 1 , a fixed blade 116 is installed on the horizontal arm of the L-shaped fixed part 101 , and a connecting plate 117 is installed on the horizontal arm of the L-shaped movable part 102 for installing a movable blade 118 .

In an embodiment, a limiting block is further provided on the horizontal arm of the L-shaped fixing member for limiting the stroke of the guide rail 108 .

Fig. 2 shows an embodiment of a stretcher transfer device using an inversion device according to an embodiment of the present invention. As shown in FIG. 2, the stretcher transfer device includes a translation mechanism 201, which is fixed to a baffle plate 202; and an overturn device 203 according to the present invention, so as to transfer the stretcher scoop to the middle of the hospital bed to scoop up the patient safely. The overturning device 203 of the present invention mainly includes an L-shaped movable part 204 and an L-shaped fixed part 205, on which a movable shoveling plate 206 and a fixed shoveling plate 207 are arranged respectively. During the transfer process of the patient, this structural design completely decouples the rotation and translation of the stretcher, which increases the safety of the transfer mechanism for scooping up the patient.

Fig. 3 shows a schematic diagram of a stretcher transfer device using a turning device according to an embodiment of the present invention after translation. Fig. 4 shows a schematic diagram of the stretcher transfer device using the turning device according to the embodiment of the present invention after translation and turning over. Fig. 5 shows a schematic diagram of the stretcher transfer device using the turning device according to the embodiment of the present invention after overall translation. As shown in Figures 3, 4 and 5, when the stretcher transfer device was in the initial state, the first motor 301 and the second motor 302 did not work, and the guide rail stretched into the groove of the L-shaped fixed part 303, so that the L-shaped movable part 304 and The L-shaped fixing part 303 is in contact. When the stretcher transfer device starts to work and scoops up patients on the hospital bed, the first motor 301 is first energized to rotate and drive the guide rail to slide along the groove in the L-shaped fixture 303, and the guide rail breaks away from the groove of the L-shaped fixture, thereby making the L-shaped movable The part 304 is separated from the L-shaped fixed part 303, leaving a space for the turning of the L-shaped movable part 304, as shown in FIG. 3 . The second motor 302 is then energized through the worm gear reducer 305 to output the rotational torque, which drives the first sprocket to rotate, and then drives the rotation of the second sprocket through the chain, and the rotation of the second sprocket drives the L-shaped movable part 304 to turn around the turning axis , and then realize the turning over of the movable shovel plate 306, as shown in FIG. 4 . The translation mechanism 307 of the stretcher transfer device works to move the fixed blade 308 to contact with the lower side of the patient's body, as shown in FIG. 5 . Thereafter, the second motor 302 reversely rotates, and the reverse flip of the movable shovel 306 is realized by the first sprocket and chain pair. When the movable shovel 306 returns to the horizontal position, the first motor 301 reversely rotates, thereby making the fixed The shovel 308 is in contact with the left side of the patient, while ensuring that the relative positions of the two stretcher shovels remain unchanged, and completes the action of scooping the patient onto the stretcher shovel.

As mentioned above, the present invention provides a turning device, which simulates the process of medical personnel scooping up patients with a manual spatula and converts it into linear motion and turning motion of driving the spatula. There will be a slipping phenomenon, which is responsible for "shoveling" the patient from the hospital bed to the transfer vehicle. The turning device only needs one person to operate remotely to transfer the patient, which reduces the work intensity of the medical staff, and reduces the dependence on the outside and the injury to the patient during the transfer process.

Apparently, the above-mentioned embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And these obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
