[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 6 A medical rehabilitation device comprises an upper fixing plate 1, a lower fixing plate 2, a control box 3 and a plurality of gear boxes 4. The gear boxes 4 are arranged between the upper fixing plate 1 and the lower fixing plate 2 and connected to the upper fixing plate 1 and the lower fixing plate 2 through a universal joint 5. The control box 3 is connected to the gear boxes 4 to control the movement of the gear boxes 4 to control the lifting and lowering movement of the upper fixing plate 1. The medical rehabilitation device is composed of four gear boxes 4, the number of which can be increased or decreased, and is connected to the control box 3 through a lead wire. The control box 3 can control the lifting and lowering of the four gear boxes 4 at the same time, without manual adjustment, to achieve the purpose of electrification.

[0021] Specifically, the gearbox 4 includes a housing 41, a motor 42, a screw rod 43, a motor gearbox 44 and a motor shaft 45. The motor 42 is arranged at one side of the housing 41 and connected to the motor shaft 45 through the motor gearbox 44. A primary gear 46 is sleeved on the motor shaft 45. The screw rod 43 is arranged at the other side of the housing 41. A secondary gear 47 is sleeved on the screw rod 43. The secondary gear 47 is meshed and connected with the primary gear 46. Both ends of the screw rod 43 are respectively connected to the universal joint 5. The working principle of the gearbox 4 is: the motor 42 drives the motor gearbox 44 to move, the motor gearbox 44 drives the primary gear 46 to move, the primary gear 46 drives the secondary gear 47 to move accordingly, and the secondary gear 47 and the screw rod 43 move synchronously, that is, when the secondary gear 47 moves, the screw rod 43 moves; when the secondary gear 47 does not move, the screw rod 43 nut does not move. This design arranges the motor 42 and the screw rod 43 on both sides of the housing 41, and rationally utilizes the space inside the housing 41, making the product smaller and more reasonable, and the internal structure is simple, which is easy to produce and assemble.

[0022] Furthermore, the screw rod 43 is sleeved with a screw knob 48, the secondary gear 47 is located above the screw knob 48, the screw knob 48 is provided with a fixing sleeve 49, and the secondary gear 47 is sleeved on the fixing sleeve 49. The screw knob 48 can only perform rotational motion, but not up and down motion. The screw rod 43 body and the screw knob 48 can only perform relative knob motion, that is, hold the screw rod 43 body with one hand and rotate the screw knob 48 with the other hand, the screw knob 48 can be rotated, but cannot move up and down. The screw rod 43 mechanism is an integral mechanism. Therefore, the secondary gear 47 can only be assembled after the screw rod 43 mechanism is finished, and the maximum diameter of the screw rod 43 is a round hole, and the round hole cannot fix the secondary gear 47, so it is necessary to cooperate with two secondary gear 47 fixing sleeves 49 so that the secondary gear 47 can be fixed on the secondary gear 47 fixing sleeve 49, and at the same time, the secondary gear 47 fixing sleeve 49 is also fixed on the screw rod knob 48. When the secondary gear 47 moves, it will drive the secondary gear 47 fixing sleeve 49 to move, and the secondary gear 47 fixing sleeve 49 will also drive the screw knob 48 to move. The movement of the screw knob 48 will drive the screw 43 to move up and down (or left and right, depending on the placement position.)

[0023] Furthermore, a flat position 481 is provided above the screw knob 48, and the inner shape of the fixing sleeve 49 is adapted to the upper part of the screw knob 48 and the shape of the flat position 481 to achieve snap-fit ​​fixation. The outer circle of the secondary gear 47 fixing sleeve 49 is slightly interference matched with the inner circle of the secondary gear 47. The inner surface of the secondary gear 47 fixing sleeve 49 is matched with the outer surface of the screw knob 48, otherwise it cannot rotate. One side of the secondary gear 47 fixing sleeve 49 has a raised feature to limit the secondary gear 47 from running outward during transportation, and the lower limit sleeve 7 of the secondary gear 47 is used to limit the secondary gear 47 from running downward during rotation.

[0024] Furthermore, a silicone pad 6 is provided between the screw 43 and the housing 41, and the silicone pad 6 is provided as a silicone pad 6 with a high friction coefficient. The purpose of adding the silicone pad 6 is that the surface of the screw 43 mechanism is cylindrical, and there is no support or force point. When the screw knob 48 moves, the body of the screw 43 mechanism will also move together, so it is necessary to press the silicone pad 6 with the housing to generate friction on the surface of the body of the screw 43 mechanism. When the friction is large enough, the body of the screw 43 will not move along the screw knob 48.

[0025] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
