[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0022] like Figures 1 to 3As shown, the wrist joint trainer with grip strength detection function of the present invention includes a detection body 10, which is used to detect the user's grip strength. The detection body 10 is provided with a manual adjustment component 20, which is used to adjust the angle of the grip 14 in the detection body 10, thereby measuring grip strength in different directions and improving detection accuracy. The detection body 10 is also provided with an automatic adjustment component 30, which can automatically adjust the angle of the grip 14 in the detection body 10, thereby improving the degree of automation.
[0023] The detection body 10 includes a housing 11, and scale lines 12 are provided on the upper surface of the housing 11. Specifically, the scale lines 12 are angle lines. A rotatable connecting member 13 is provided on the housing 11, and a grip 14 is provided on the connecting member 13. A pressure sensor is provided on the grip 14 for detecting the user's grip strength. Among them, a moving block 131 is slidably connected to one end of the upper surface of the connecting member 13, and a fixing member 132 is threadedly connected to one side of the connecting member 13. A through hole is also provided on one side of the connecting member 13, and an adjusting member 141 is movably connected inside the through hole. The shape of the adjusting member 141 is arc-shaped, and the shape of the adjusting member 141 is adapted to the shape of the through hole, so that the adjusting member 141 can rotate in the through hole, and the grip 14 is mounted on the adjusting member 141. With the above structure, the grip 14 can be moved horizontally by the action of the moving block 131 to adapt to the arm length of different users. Through the cooperation between the connecting member 13 and the adjusting member 141, the adjusting member 141 can be rotated in the through hole of the connecting member 13, thereby adjusting the angle of the grip 14. When the user's grip strength is tested, the user's grip strength at different angles can be measured, thereby improving the comprehensiveness and accuracy of the test.
[0024] The detection body 10 also includes a fixing plate 15 fixed to one side of the housing 11. The upper surface of the fixing plate 15 has a sliding hole. A slidable armrest 16 is mounted on the fixing plate 15. Specifically, the outer surface of the armrest 16 has a threaded rod. One end of the threaded rod passes through the sliding hole and is secured by a nut, which is threaded onto the rod. With this structure, the armrest 16 can be adjusted to suit different user arm lengths by sliding it into the appropriate position and tightening the nut.
[0025] The manual adjustment assembly 20 includes multiple support columns 21 fixed to the interior of the housing 11. Two of the support columns 21 are bolted to limit members 22. A bearing is fixedly attached to the inner surface of the limit member 22, and a worm 23 is fixedly attached to the inner surface of the inner ring of the bearing, allowing the worm 23 to rotate. Furthermore, an adjustment knob 24 is fixedly attached to one end of the worm 23. One end of the adjustment knob 24 passes through a side of the housing 11 and is fixedly attached to the adjustment knob 24. Specifically, one end of the adjustment knob 24 has a round rod 241, one end of which is fixed to one end of the worm 23. With this structure, turning the adjustment knob 24 causes the worm 23 to rotate.
[0026] A rotating member 25 is also rotatably connected to the inner bottom wall of the housing 11. A worm gear 26 is fixedly connected to the outer surface of the rotating member 25. The worm gear 26 mates with the worm 23 and is threadedly connected to the worm 23. When the adjustment knob 24 rotates the worm 23, the worm 23 rotates the worm gear 26, which in turn rotates the rotating member 25, thereby rotating the connecting member 13 and ultimately the handle 14. It should be noted that during the rotation of the connecting member 13, the adjustment angle can be controlled using the scale line 12.
[0027] The automatic adjustment assembly 30 includes a protective housing 31, which houses a motor. The motor's main shaft is fixedly connected to an output shaft 32, which drives the output shaft 32 to rotate. A first gear 33 is also fixedly connected to one end of the output shaft 32. A second gear 34 is also fixedly connected to the outer surface of the rotating member 25. The second gear 34 is located below the worm gear 26 and meshes with the first gear 33. With this structure, when the motor is started, it rotates the first gear 33. The engagement of the first and second gears 33 and 34 drives the rotating member 25, which in turn drives the connecting member 13 to adjust the angle of the grip 14.
[0028] Working principle: When in use, first adjust the grip 14 to a suitable angle through the manual adjustment component 20 or the automatic adjustment component 30, then place the arm on the arm rest 16, and fix the user's arm with a strap, then the user's hand holds the grip 14 and holds the grip 14 tightly, and the user's grip strength is recorded by the pressure sensor on the grip 14.
