A connecting ring 24 and a limiting cap are fixedly connected to each eccentric shaft 23, and each disk 22 is located between the connecting ring 24 and the limiting cap on the connected eccentric shaft 23, so as to ensure that the eccentric shaft 23 does not slide away from the disk 22.

[0044] The two receiving rods 26 are fixedly connected to the single bed 1, and a movable part 25 is rotatably mounted on each receiving rod 26. Each movable part 25 is composed of two parallel connecting plates, and each connecting plate is rotatably connected to the receiving rod 26. A pull shaft is vertically arranged between the two connecting plates on the same receiving rod 26, and each pull shaft is fixedly connected to the two connecting plates. The two pull shafts correspond to the two connecting rings 24 one by one, and each connecting ring 24 is slidably sleeved on the corresponding pull shaft. It is used to drive the connecting plate to rotate around the receiving rod 26.

[0045] The two movable members 25 correspond to the two support shafts 36 one by one, and each support shaft 36 penetrates the two connecting plates of the corresponding movable member 25 and is rotatably connected with the two connecting plates, so as to drive the two support shafts 36 to rotate closer or farther along the horizontal plane.

[0046] like Figure 2 and Figure 7 As shown, the single bed 1 is equipped with a second linkage, and the two placement plates 30 are matched with the support shaft 36 through the second linkage. The second linkage includes two second gears 28 and two second racks 33. The two second gears 28 correspond to the two support shafts 36 one by one, and each second gear 28 is fixedly sleeved on the corresponding support shaft 36. Two arc grooves are cut out of the top of the single bed 1 in the vertical direction, and the two arc grooves are connected to the inside and outside of the installation cavity of the single bed 1. The two arc grooves correspond to the two second gears 28 one by one, and each second gear 28 is located in the corresponding arc groove. The two second racks 33 correspond to the two arc grooves one by one, and each second rack 33 is an arc rack matching the corresponding arc groove, and each second rack 33 is located in the corresponding arc groove and is fixedly connected to the single bed 1.

[0048] Two second chutes are chiseled out on the single bed 1, and the two second chutes correspond to the two arc-shaped chutes one by one, and each second chute is opened along the direction of the corresponding arc-shaped chutes. The notch of each second chute is vertically upward and the vertical section is inverted T-shaped. Each second chute is limitedly slidably matched with an arc-shaped limit block 34 that matches the second chute, and a telescopic rod 35 is welded and fixed on the top of each limit block 34, and each telescopic rod 35 passes upward through the second chute where the limit block 34 is connected.

[0049] The two telescopic rods 35 correspond to the two placement plates 30 one by one, and the telescopic shaft of each telescopic rod 35 is fixedly connected to the corresponding placement plate 30 to ensure that the placement plate 30 does not rotate with the third screw rod 27.

[0050] like Fig. 9 As shown, each placement plate 30 is chiseled with a receiving groove in the horizontal direction, and each receiving groove is equipped with an extension plate 32, and each extension plate 32 is limited and slidably matched with the placement plate 30. A fourth screw rod 31 is horizontally arranged in each placement plate 30 along the sliding direction of the extension plate 32, and each fourth screw rod 31 is rotatably connected to the placement plate 30 where it is located, and is also threadedly connected to the extension plate 32 in the placement plate 30 where it is located. Each fourth screw rod 31 and the connected extension plate 32 together form a ball screw pair through a ball, which is used to drive the extension plate 32 to slide in and out of the storage groove.

[0051] A knob is rotatably mounted on each placement plate 30 , and each knob is coaxially fixedly connected to a fourth screw rod 31 in the placement plate 30 .

[0052] A fixing block is rotatably connected to the rod body of each first screw rod 10 close to the connected fourth bevel gear 9, the rod body of each first rotating rod 6 close to the connected second bevel gear 7 and third bevel gear 8, and the rod body of each second rotating rod 20 close to the connected sixth bevel gear 21, and each fixing block is fixedly connected to the single bed 1. It is used to ensure that the first bevel gear 4 does not disengage from the second bevel gear 7, the third bevel gear 8 does not disengage from the fourth bevel gear 9, and the fifth bevel gear 18 does not disengage from the sixth bevel gear 21.

[0053] Working principle: When in use, the patient lies on the single bed 1 and is located under the support frame 11. Then the patient grasps the two hanging rings 15 with both hands, and the patient's legs are placed on the two placement plates 30. Then, according to the patient's leg length, the knob on the placement plate 30 is turned, and the knob drives the fourth screw rod 31 to rotate, and the fourth screw rod 31 pushes the extension plate 32 to slide out of the storage slot, thereby adapting to the patient's leg length. Then, the patient's legs are fixed with straps.

[0054] Then, the motor 2 is started, and the output shaft of the motor 2 drives the connecting rod 3 to rotate, and the connecting rod 3 drives the two first bevel gears 4 and the two fifth bevel gears 18 to rotate.

[0055] At this time, the two first bevel gears 4 drive the two second bevel gears 7 to rotate, and the two second bevel gears 7 drive the connected first rotating rods 6 to rotate. The two first rotating rods 6 drive the connected third bevel gears 8 to rotate, and the two third bevel gears 8 drive the connected first screw rods 10 to rotate. The two first screw rods 10 drive the support frame 11 to move up and down, and the support frame 11 drives the two moving blocks 14 to move up and down synchronously, and the two moving blocks 14 drive the connected hanging rings 15 to move up and down synchronously. The two hanging rings 15 drive the patient's arms to perform arm lifting training.

[0056] During the up and down movement of the support frame 11, the first gear 16 is driven to move up and down. The first rack 17 drives the first gear 16 to rotate, and the first gear 16 drives the second screw rod 13 to rotate. The second screw rod 13 drives the two moving blocks 14 to slide closer or farther, and the two moving blocks 14 drive the two hanging rings 15 to move closer or farther. The two hanging rings 15 drive the patient's arms to separate and merge training.

[0057] At the same time, the two fifth bevel gears 18 push the two sixth bevel gears 21 to rotate, and the two sixth bevel gears 21 drive the connected second rotating rods 20 to rotate. The two second rotating rods 20 drive the connected disk 22 to rotate, and the two eccentric shafts 23 revolve around the central axis of the disk 22 with the disk 22. In this process, the two eccentric shafts 23 drive the connected connecting ring 24 to revolve around the central axis of the disk 22 synchronously. During the revolution of the connecting ring 24, it slides up and down along the sleeved pull shaft, and at the same time pushes the sleeved pull shaft to reciprocate along the arc around the receiving rod 26 connected to the movable part 25 where the pull shaft is located. During the revolution of the pull shaft, the movable part 25 is driven to reciprocate around the connected receiving rod 26, and the movable part 25 pushes the connected support shaft 36 to reciprocate along the arc, and the two support shafts 36 rotate closer or farther.

[0058] When the two support shafts 36 rotate toward or away from each other, the connected second gear 28 and the third screw rod 27 are driven to move synchronously. When the third screw rod 27 moves, the connected internal threaded cylinder 29 is pushed to move synchronously, and the internal threaded cylinder 29 pushes the connected placement board 30 to move synchronously. The two placement boards 30 drive the patient's legs to perform separation and merging training.

[0059] During the movement of the second gear 28, the second rack 33 drives the meshed second gear 28 to rotate, the second gear 28 drives the sleeved support shaft 36 to rotate, and the support shaft 36 drives the connected third screw rod 27 to rotate. The third screw rod 27 drives the connected internal threaded cylinder 29 to move up and down, and the internal threaded cylinder 29 drives the connected placement plate 30 to move up and down. The two placement plates 30 drive the patient's legs to perform leg lifting training.

[0060] When the two placement plates 30 move closer or farther away, they drive the connected telescopic rod 35 to move synchronously, and the telescopic rod 35 drives the connected limit block 34 to slide in the second slide groove, thereby ensuring that the two placement plates 30 do not rotate with the third screw rod 27.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
