Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-8, an embodiment of the invention provides a finger trainer for rehabilitation, which comprises two fixing rods 1, wherein a same frame box 2 is fixedly installed between the two fixing rods 1, a plurality of strip-shaped rods 3 are movably installed on one side of the frame box 2, a finger ring 4 is installed at one end of each strip-shaped rod 3, a plurality of through holes 5 are formed in the inner wall of one side of the frame box 2, one end of each strip-shaped rod 3 penetrates through the through holes 5, a tension variation device is arranged at one end of each strip-shaped rod 3 in the frame box 2 and comprises a base 6 fixed on the inner side wall of the frame box 2, two sliding guide columns 7 are fixed on the base 6 at intervals, a limit block 8 is arranged at the top end of each sliding guide column 7, a sliding block 9 is installed between the two sliding guide columns 7 in a sliding manner, the sliding block 9 is fixedly connected with the strip-shaped rods 3, a hollow cylindrical cavity 10 is arranged in the sliding block 9, a first guide strip 11 and a second guide, the first guide strip 11 and the second guide strip 12 are identical in structure and are both wavy, the first guide strip 11 and the second guide strip 12 are arranged at intervals in a staggered manner, a wavy guide channel 13 is formed between the first guide strip 11 and the second guide strip 12, a cylinder 14 is arranged in the cylinder cavity 10 in a sliding manner, guide posts 15 are symmetrically arranged on two sides of the cylinder 14, the guide posts 15 are accommodated on the guide channel 13, a connecting rod 16 is arranged at one end of the cylinder 14, a through groove 17 is arranged in the middle of the base 6, one end of the connecting rod 16 penetrates through the through groove 17 and is fixedly connected with a traction block 18, the traction block 18 can penetrate through the through groove 17 under the traction movement of the cylinder 14, a first spring is fixed between the sliding block 9 and the base 6, the connecting rod 16 comprises a first connecting rod 161 fixedly connected with the cylinder 14 and a second connecting rod 162 fixedly connected with the traction block 18, a groove portion 163 is arranged in the first connecting rod 161, and a second spring, the second link 162 is provided with a sleeve portion 164, the sleeve portion 164 is sleeved outside the groove portion 163, and one end of the second spring 165 is connected to the bottom of the sleeve portion 164.
In the present invention, the first guide strip 11 includes four identical first wave-shaped tips 111 and four identical first wave-shaped bottoms 112, the second guide strip 12 includes four identical second wave-shaped tips 121 and four identical second wave-shaped bottoms 122, and the first wave-shaped tips 111 and the second wave-shaped bottoms 122 have a misalignment in the axial direction of the cylinder 14. The first guide strip and the second guide strip are both in a wave shape, and the wave tip part and the wave bottom part are arranged at intervals. When the guide post 15 on the cylinder 14 reciprocates in the axial direction of the cylinder, the guide post 15 is guided by the guide channel 13, and the guide post 15 can advance along the guide channel 13, thereby rotating the cylinder 14.
The working principle and the process are as follows: as shown in fig. 3, in the initial position, the guide post 15 on the cylinder 14 is located at the second wave bottom 122 of the second guide bar 12, the connecting rod 16 passes through the through slot 17, the length direction of the pulling block 18 crosses the length direction of the through slot 17 at 90 degrees, neither the first spring nor the second spring is stressed, the finger pulls the finger ring 4, the pulling block 18 is pulled by the second spring 21 to abut against the through slot 17, the pulling block 18 cannot pass through the through slot 17 due to the stop of the through slot 17, the finger ring 4 drives the sliding block 9 to slide by the bar-shaped rod 3, the finger needs to overcome the pulling force of the first spring 20 and the second spring 165, when the pulling force needs to be adjusted, the bar-shaped rod 3 is pushed once towards the inside of the frame box 2 by the finger ring 4 and is released and restored, the movement trajectory of the guide post 15 on the cylinder 14 is such that the guide post 15 moves along the guide channel 13, due to the offset relationship between the first guide bar 11 and the second, the guide post 15 moves from the bottom of the second wave to the bottom of the adjacent second wave and drives the cylinder 14 to rotate 90 degrees, the traction block 18 is not stopped by the through groove 17 and can freely pass through the through groove 17, therefore, when the finger pulls the ring 4 to move, the second spring 165 is not stressed, the first spring 20 is stressed, and the effect of adjusting the tension is achieved. The pulling force value can be adjusted once only by pressing the finger ring once inwards, and the finger ring can be operated circularly and is convenient and fast to adjust. The training purpose can be achieved by continuously pressing the finger ring, the pressure of the first spring needs to be overcome by pressing the finger ring, and the composite movement can be performed by pressing and pulling.
As an improved scheme, a slide guiding strip 166 may be disposed on an outer side wall of the groove portion 163, and the slide guiding strip 166 is slidably disposed on a sliding groove 167 of the socket portion 164, so that the first link 161 and the second link 162 can only slide relatively and cannot rotate relatively.
In the invention, the two ends of the two fixed rods 1 are movably provided with the threaded rods 23, one end of each threaded rod 23 is movably provided with the connecting block 24, and the same holding rod 25 is fixedly arranged between the two connecting blocks 24, so that a fulcrum is conveniently provided for a hand, and the finger training is conveniently carried out.
In the invention, one end of each of the two fixing rods 1 is provided with a thread groove 26, one end of each of the two threaded rods 23 is respectively installed in the two thread grooves 26 in a threaded manner, one side of each of the two connecting blocks 24 is provided with a rotating groove, the other end of each of the two threaded rods 23 is respectively installed in the two rotating grooves in a rotating manner, the threaded rods 23 are screwed with nuts 28, and the nuts 28 are abutted against the end parts of the fixing rods 1 to fix the threaded rods 23. When different users use, especially child and adult, the palm is not of uniform size, stretches out the length of thread groove through adjusting the threaded rod, and adjustable palm is holding the distance between palm and the ring behind the holding rod to the better training that carries out the finger.
In the rehabilitation training that carries out the finger function, use the finger training ware, the accessible pulling ring trains, adjust the pulling force through pressing the ring, thereby it is more targeted to make the rehabilitation training, more have extensive adaptability, initial stage training can be adjusted to less pulling force value, make the finger adapt to the training equipment gradually, with going on and the rehabilitation of training, can adjust to great pulling force value, still accessible pulling, the alternative training action of pressing comes to carry out many-sided function rehabilitation to the finger, stretch out the length of thread groove through adjusting the threaded rod, adjustable palm is the distance between palm and the ring behind the holding rod, thereby better training of carrying out the finger.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
