[0054] When the rotation driving assembly is in operation, the first gear 6 is driven to rotate, because the first gear 6 is engaged with the first rack 5, thus, when the first gear 6 rotates, the first rack 5 is driven to translate. The first rack 5 is fixedly installed on the bottom surface of the slide table 4 by welding or bolting, thus, the first rack 5 can drive the slide table 4 and the transfer bed 3 fixedly connected with the slide table 4 to translate on the top surface of the transfer main body 1.

[0055] Optionally, the rotation driving assembly comprises a slide plate 7, a second rack 8, a third rack 9, a motor 10 and a second gear 11.

[0056] The slide plate 7 is a plastic flat plate. The installation slot 101 extends through the transfer main body 1 in the first direction, the slide plate 7 is slidingly installed in the installation slot 101 in the first direction, a through hole 701 is formed in the middle position of the slide plate 7, the first gear 6 is rotatably installed in the through hole 701, the second rack 8 is welded or bolted on the bottom of the installation slot 101 and extends in the first direction, the second rack 8 is engaged with the first gear 6, the first rack 5 and the second rack 8 are respectively located on the upper and lower sides of the first gear 6, the third rack 9 is bolted or hot-melt connected on the bottom surface of the slide plate 7 and extends in the first direction, an installation hole 102 is formed in the bottom of the installation slot 101, the motor 10 is installed in the installation hole 102 and the rotating shaft of the motor 10 faces upward and extends into the installation slot 101, the second gear 11 is rotatably installed in the installation slot 101, the second gear 11 is installed on the rotating shaft of the motor 10, and the second gear 11 is engaged with the third rack 9.

[0057] When the motor 10 is in operation, the second gear 11 is driven to rotate in the installation slot 101, because the second gear 11 is engaged with the third rack 9 and the third rack 9 is fixedly installed on the bottom surface of the slide plate 7, thus, the rotating second gear 11 drives the third rack 9 to slidingly translate the slide plate 7 in the installation slot 101 in the first direction. The first gear 6 is rotatably installed in the through hole 701 on the slide plate 7 through a round shaft, and the first gear 6 is engaged with the second rack 8 fixedly installed on the bottom of the installation slot 101, thus, when the slide plate 7 translates in the installation slot 101, the first gear 6 is dragged to roll on the second rack 8, and the first gear 6 is driven to rotate. The first rack 5 and the second rack 8 are respectively located on the two sides of the first gear 6 and are engaged with the first gear 6, thus, the rolling first gear 6 drives the first rack 5 to translate.

[0058] In this embodiment, the rotating movement output by the motor 10 is first transmitted to the sliding plate 7 through the second gear 11 and the third rack 9, and then the sliding plate 7 drags the first gear 6 to roll on the second rack 8, and then the power is transmitted to the sliding table 4 through the cooperation of the first gear 6 and the first rack 5. Therefore, the second rack 8 and the third rack 9 form a first gear and rack transmission pair, and the first gear 6 and the first rack 5 form a headphone gear and rack transmission pair, so as to better transmit the power output by the motor 10 to the sliding table 4 and the transfer bed 3.

[0059] Of course, a power supply and a controller (for example, a circuit board) are also included, the power supply and the motor 10 are electrically connected with the controller, so as to control the operating state (for example, the rotating speed and the rotating direction) of the motor 10 by the controller. The controller is integrated with a signal receiving unit, and a remote controller is also included and is in communication connection with the signal receiving unit. In this way, the medical staff or the patient can control the operating state of the motor 10 by the remote controller, so as to control the movement of the transfer bed 3 on the transfer device main body 1.

[0060] In order to make the sliding plate 7 slide more smoothly in the mounting groove 101, a guide part for guiding the sliding plate 7 is further arranged between the transfer bed 3 and the sliding plate 7 in this embodiment. Optionally, the guide part includes a second linear guide rail 12 extending in the first direction, which is integrally formed or bolted on the inner side wall of the mounting groove 101 at the groove opening. A sliding groove 702 is formed on the outer side wall of the sliding plate 7, and the second linear guide rail 12 is in sliding cooperation with the sliding groove 702. In this way, the sliding plate 7 can only translate in the first direction in the mounting groove 101. Moreover, the number of the second linear guide rails 12 is two, and the two second linear guide rails 12 are respectively arranged on the two side groove walls of the mounting groove 101.

In this way, the movement of the sliding plate 7 is better positioned and guided.

[0061] Optionally, the number of the first linear guide rails 2 is two, and the two first linear guide rails 2 are respectively located on the two sides of the mounting groove 101. Correspondingly, the number of the sliding ways 401 on the bottom surface of the sliding table 4 is also two, and the two sliding ways 401 are in one-to-one cooperation with the two first linear guide rails 2. In this way, the translation of the transfer bed 3 and the sliding table 4 on the transfer device main body 1 is more stable. It is worth noting that the first linear guide rail 2 in this embodiment is a T-shaped rail, and the sliding way 401 is adapted to the first linear guide rail 2. In this way, after the cooperation of the first linear guide rail 2 and the sliding way 401, the transfer bed 3 will not be overturned on the transfer device main body 1. Even if the patient lies on the transfer bed 3 and the transfer bed 3 travels to the limit position of a side of the transfer device main body 1, the transfer bed 3 will not be overturned.

[0062] In order to avoid the slide plate 7 from sliding out of the mounting groove 101 on the transporter main body 1, in the embodiment, a blocking part is further arranged between the transfer bed 3 and the slide plate 7, which is used to block the slide plate 7 from completely sliding out of the mounting groove 101 and falling. Optionally, the blocking part comprises a first boss 103, a second boss 104 and a blocking strip 703, wherein:

[0063] The first boss 103 and the second boss 104 are both fixedly installed on the groove bottom of the mounting groove 101.

The first boss 103 and the second boss 104 are respectively located at the first end and the second end, and the first boss 103 and the second boss 104 are staggered. The blocking strip 703 is fixedly installed on the bottom surface of the slide plate 7, and the blocking strip 703 is collinear with the central axis (i.e. the circular shaft) of the first gear 6. When the slide plate 7 slides to the first end, the blocking strip 703 abuts against the first boss 103, so as to avoid the slide plate 7 from completely sliding out of the mounting groove 101 from the first end; when the slide plate 7 slides to the second end, the blocking strip 703 abuts against the second boss 104, so as to avoid the slide plate 7 from completely sliding out of the mounting groove 101 from the first end.

[0064] Specifically, the first boss 103 and the second boss 104 are located on the same side of the second rack 8, and the first boss 103 and the second gear 11 are respectively located on the two sides of the second rack 8.
