in the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "lateral", "vertical", and the like, indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 1, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the present invention.
As shown in fig. 1 to 9, this embodiment provides an adjustable seat for lower limb rehabilitation training, including a seat cushion 1 and a backrest 2, both sides of the seat cushion 1 are provided with angle adjusters 3, the angle adjusters 3 are connected to the backrest 2 through an upper support plate 4, two transmission connecting rods 5 are provided between the angle adjusters 3, specifically, the transmission connecting rods 5 are seven star bars, and the end portions of the transmission connecting rods 5 penetrate through the angle adjusters 3 and are fixedly connected with the angle adjusters 3, in this embodiment, a hand wheel 6 is fixedly provided at one end of the transmission connecting rods 5, and the transmission connecting rods 5 are driven to rotate by rotating the hand wheel 5, so as to drive the two angle adjusters 3 to rotate, and then drive the upper support plate 4 and the backrest 2 to rotate, thereby realizing angle adjustment of the backrest 2.
Specifically, seat connecting support plates 7 are fixedly arranged on two sides of the seat cushion 1, one end of each seat connecting support plate 7 is fixedly connected with the angle adjuster 3, a through hole is formed in the middle of one end of each seat connecting support plate 7, the transmission connecting rod 5 penetrates through the through hole, a limiting protrusion 701 is arranged on the upper portion of each seat connecting support plate 7, and an angle limiting column 401 is arranged on one side, facing the seat connecting support plate 7, of the upper support plate 4. When the backrest is adjusted steplessly by rotating the hand wheel 5, the angle limiting column 401 moves along with the rotation of the upper support plate 4, and after the angle limiting column 401 is contacted with the limiting protrusion 701, the hand wheel 5 cannot be rotated, so that the rotation angle of the backrest 1 is limited, large-angle change cannot occur during adjustment and use, the safety of a trainer is protected, and the use safety is improved. In addition, the angle adjuster 3 can be adjusted steplessly, and is convenient for the operation of patients and rehabilitation teachers.
Further, the adjustable seat for lower limb rehabilitation training that this embodiment provided still includes handrail frame 8, the one end of handrail frame 8 is the loop configuration, go up fixed rotation axis 402 that is provided with on the extension board 4, the loop configuration of handrail frame 8 one end is established on rotation axis 402 through damping adjustment mechanism 9 cover.
Specifically, the damping adjustment mechanism 9 includes a friction plate 901, a limiting disc 902, a cover plate 903, and a pin 904. The friction plate 901 is sleeved on the rotating shaft 402, and the friction plate 901 is in contact with the upper support plate 4; the middle part of the limiting disc 902 is provided with three stepped holes, the limiting disc 902 is sleeved on the rotating shaft 402, one end of the limiting disc 902 is sleeved in the annular structure of the armrest frame 8, the other end of the limiting disc 902 faces the friction plate 901 and is in contact with the friction plate 901, the large-diameter section hole of the limiting disc 902 is sleeved with the cover plate 903, the middle section hole of the limiting disc 902 is rotatably connected with the rotating shaft 402 through a bearing, the small-diameter section hole of the limiting disc 902 is sleeved with a top sleeve 905, one end of the top sleeve 905 is in contact with the friction plate 901, and the other end of the top sleeve 905 is in contact with the inner ring of the bearing; the cover plate 903 is sleeved on the rotating shaft 402 and clamped with the rotating shaft 402; the pin 904 is screwed to the rotary shaft 402 through the cover plate 903.
When the handrail frame 8 is rotated, the limiting disc 902 rotates along with the handrail frame 8, and the handrail frame 8 is fixed by the friction force when the handrail frame 8 stops rotating due to the extrusion friction force between the limiting disc 902 and the friction plate 901. When the friction between the limiting disc 902 and the friction plate 901 needs to be increased, that is, the resistance when the armrest frame 8 is rotated and the fixing firmness of the armrest frame 8 are increased, the purpose can be achieved by tightening the pin 904. When the pin 904 is rotated to tighten the pin 904 with the rotating shaft 402, the advance of the pin 904 presses the cover plate 903 and the stopper disc 902 further toward the friction plate 901, increasing the pressing friction force between the stopper disc 902 and the friction plate 901. To reduce the friction between the limiting disc 902 and the friction plate 901, the pin 904 may be screwed in the opposite direction.
Through the damping adjustment mechanism 9, the armrest frame 8 can rotate and stay within the set angle range, and a patient can conveniently get in and out of the device.
