Description

Technical Field

[0001] The utility model relates to the field of finger trainers, in particular to a finger fine function trainer. Background Art

[0002] Finger fine function trainers can help improve the movement accuracy and coordination of fingers, and increase the flexibility and coordination of finger muscle groups. Therefore, finger fine function trainers can be suitable for a wide range of people. Normal people using finger fine function trainers can make their fingers more sensitive, increase the perception of touch, and improve work efficiency. Moreover, finger fine function trainers play a role in promoting the recovery of hand function and increasing self-care ability for patients with hand movement dysfunction, patients who need rehabilitation after hand injuries, etc.

[0003] At present, there are many different types of finger fine function trainers on the market. Among them, there is a finger fine function trainer that first binds the user's finger to a traction rope, and a restraint plate is bound to the other end of the traction rope. A spring is sleeved on the traction rope. When the finger is clenched or released, the finger drives the traction rope and the restraint plate to move. When the restraint plate presses the spring, the finger is trained. However, when training the finger, it is necessary to bind the finger and the traction rope, and the operation is cumbersome. The end of the traction rope of some trainers is fixed with a finger fixing ring, but the size of the finger fixing ring cannot meet fingers of different thicknesses. If an elastic fixing ring is used, when the finger is clenched, the traction rope will also pull the elastic fixing ring, causing it to deform and easily come off. Moreover, the spring is not easy to replace and cannot be adjusted according to the need to adjust the training intensity. Summary of the Utility Model

[0004] (1) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide a finger fine function trainer, and the technical problem it aims to solve is that when training the finger, it is necessary to bind the finger and the traction rope, and the operation is cumbersome. The end of the traction rope of some trainers is fixed with a finger fixing ring, but the size of the finger fixing ring cannot meet fingers of different thicknesses. If an elastic fixing ring is used, when the finger is clenched, the traction rope will also pull the elastic fixing ring, causing it to deform and easily come off. Moreover, the spring is not easy to replace and cannot be adjusted according to the need to adjust the training intensity.

[0006] (2) Technical Solution

[0007] To achieve the above technical purpose, the present utility model provides a finger fine function trainer:

[0008] It includes a mounting plate, a curved plate and a wrist cushion plate are fixed on the top of the mounting plate, and an elastic band is fixed on the wrist cushion plate. Five traction ropes are slidably connected in the curved plate, and one end of the traction rope is fixed with a threaded tube. A restraint plate is arranged at the other end of the traction rope. A spring is sleeved outside the traction rope. One end of the spring abuts against the curved plate, and the other end of the spring abuts against the restraint plate. A fixing component for fixing it to the finger is arranged in the threaded tube.

[0009] Preferably, the fixing component includes a rubber airbag fixed on the inner wall of the threaded tube. A partition plate is fixed in the middle of the threaded tube. An air vent groove is opened in the partition plate, and the air vent groove is communicated with the rubber airbag.

[0010] Preferably, the partition plate divides the inside of the threaded tube into an upper chamber and a lower chamber. The rubber airbag is located in the lower chamber. An air conveying member for squeezing the air in the upper chamber into the rubber airbag or pumping the air in the rubber airbag into the upper chamber is arranged on the threaded tube.

[0011] Preferably, the air conveying member includes a piston sealingly and slidably fitted in the upper chamber, and a cylindrical rod is fixed on the top of the piston.

[0012] Preferably, a nut is threadedly connected to the outside of the threaded tube, and a round hole is opened at the top of the nut. The cylindrical rod passes through the round hole and rotates in the round hole.

[0013] Preferably, a pressing plate and a ring are fixed on the top of the cylindrical rod, and the top of the nut is located between the pressing plate and the ring. The diameters of the pressing plate and the ring are larger than the diameter of the round hole.

[0014] Preferably, a threaded hole is opened on one side of the restraint plate. A stud is fixed at the end of the traction rope away from the threaded tube, and the stud is threadedly connected to the threaded hole.

[0015] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0016] 1: Insert the five fingers into the five threaded tubes in sequence. Usually rotate the nut to make the threaded tube move upward. When the nut moves, it drives the cylindrical rod and the piston to move towards the partition plate, so as to squeeze the air in the upper chamber of the threaded tube into the rubber airbag through the air vent groove. The rubber airbag is inflated, so that the rubber airbag tightly wraps the finger, making the finger fixed to the threaded tube. Since the thicknesses of the five fingers are different, and the thicknesses of the fingers of different users are also different, that is, this method can fix fingers of different thicknesses, and this fixing method is more convenient.

[0017] 2: When springs with different elastic coefficients are needed, turn the stud to remove it from the screw hole, and take the spring off the traction rope, then different elastic coefficient springs can be replaced, and different elastic coefficient springs can be replaced according to the change of training intensity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.

[0024] Refer to Figures 1-3 :

[0025] The finger fine function trainer provided by the present utility model includes a mounting plate 1. A curved plate 2 and a wrist cushion plate 3 are fixed on the top of the mounting plate 1. An elastic band 4 is fixed on the wrist cushion plate 3. Five traction ropes 6 are slidably connected in the curved plate 2. One end of the traction rope 6 is fixed with a threaded tube 5, and the other end of the traction rope 6 is provided with a restraint plate 7. A spring 8 is sleeved outside the traction rope 6. One end of the spring 8 abuts against the curved plate 2, and the other end of the spring 8 abuts against the restraint plate 7. A fixing component for fixing it to the finger is arranged in the threaded tube 5.

[0026] Specifically, the fixing component includes a rubber air bag 19 fixed on the inner wall of the threaded tube 5. A partition plate 9 is fixed in the middle of the threaded tube 5. An air vent groove 10 is opened in the partition plate 9, and the air vent groove 10 is communicated with the rubber air bag 19. The partition plate 9 divides the inside of the threaded tube 5 into an upper chamber and a lower chamber. The rubber air bag 19 is located in the lower chamber. An air delivery component is arranged on the threaded tube 5 for squeezing the air in the upper chamber into the rubber air bag 19 or pumping the air in the rubber air bag 19 into the upper chamber.

[0027] When in use, first pull up the elastic band 4, then pass the hand through the elastic band 4, and then release the elastic band 4 so that the elastic band 4 fixes the mounting plate 1 on the wrist. Then insert the five fingers into the five threaded tubes 5 in sequence. Since the thicknesses of the five fingers are different and the finger thicknesses of different users are also different, usually rotate the nut 13 to move it upward on the threaded tube 5. When the nut 13 moves, it drives the cylindrical rod 12 and the piston 11 to move towards the partition plate 9, so that the piston 11 squeezes the air in the upper chamber of the threaded tube 5 into the rubber air bag 19 through the air vent groove 10. The rubber air bag 19 inflates and expands, so that the rubber air bag 19 tightly wraps the finger, thereby fixing the finger to the threaded tube 5.

[0028] Furthermore, the air delivery component includes a piston 11 that is hermetically and slidably fitted in the upper chamber. The top of the piston 11 is fixed with a cylindrical rod 12. The threaded tube 5 is externally threaded with a nut 13, and a round hole 14 is opened at the top of the nut 13. The cylindrical rod 12 passes through the round hole 14 and rotates in the round hole 14. The top of the cylindrical rod 12 is fixed with a pressure plate 15 and a ring 16, and the top of the nut 13 is located between the pressure plate 15 and the ring 16. The diameters of the pressure plate 15 and the ring 16 are larger than the diameter of the round hole 14. A threaded hole 17 is opened on one side of the restraint plate 7. One end of the traction rope 6 away from the threaded tube 5 is fixed with a stud 18, and the stud 18 is threadedly connected with the threaded hole 17.

[0029] In use, when the finger and the threaded tube 5 are fixed, when the finger is clenched, it drives the threaded tube 5 to move, thereby driving the traction rope 6 to pull the restraint plate 7, so that the restraint plate 7 compresses the spring 8, which plays a role in training the finger. When springs 8 with different elastic coefficients are needed, the stud 18 is rotated to move the stud 18 out of the screw hole 17, and the spring 8 is removed from the traction rope 6, and then the spring 8 with a different elastic coefficient can be replaced.

[0030] In the foregoing, the exemplary embodiments of the solutions proposed in the present disclosure have been described in detail with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed in the present disclosure can be made without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
