[0023] Reference Figure 1-Figure 5 , an upper limb handle quick-change mechanism of an active and passive rehabilitation training device, comprising a device body 1, the device body 1 comprising an upper limb trainer 4 and a lower limb trainer 2, the upper limb trainer 4 is arranged above the lower limb trainer 2, a display screen 3 is arranged on the top of the upper limb trainer 4, a mounting seat 5 is arranged inside the upper limb trainer 4, a motor 6 is arranged on the surface of the mounting seat 5, a right mounting crank 9 is arranged on one side of the motor 6, a first handle 10 is arranged on the outside of the right mounting crank 9, a left mounting crank 11 is arranged on the side of the output end of the motor 6 originally away from the right mounting crank 9, a second handle 12 is arranged on the outside of the left mounting crank 11, a connecting shaft 13 is arranged through the right mounting crank 9, a shaft sleeve 18 is sleeved inside the first handle 10, a handle shaft 16 is sleeved inside the shaft sleeve 18, a reset spring positioning piece 17 is arranged inside the first handle 10, and a quick lock piece 14 is arranged on one side of the shaft sleeve 18.
[0024] In this embodiment, the return spring positioning member 17 is fixed in the cavity of the first handle 10, and the fixed end of the quick lock member 14 is fixed to the first handle 10 through the fixed bushing 15 and can rotate freely around the fixed bushing 15. The fixed bushing 15 fixed to the first handle 10 is used as a stopper for the rotating end of the quick lock member 14. When the rotating end of the quick lock member 14 rotates to the fixed bushing 15, it cannot continue to rotate. At this time, the quick lock member 14 is positioned by the return spring positioning member 17 fixed in the cavity of the first handle 10. After the quick lock member 14 is positioned by the return spring positioning member 17, the inner surface of the quick lock member 14 The handle shaft 16 can be blocked to prevent the handle shaft 16 from sliding out freely in the axial direction. The quick lock member 14 is pushed slightly with a finger, and the return spring positioning member 17 is compressed after being subjected to the force, and the quick lock member 14 is no longer positioned. The quick lock member 14 can rotate around the fixed bushing 15. The quick lock member 14 is rotated so that the quick lock member 14 no longer blocks the handle shaft 16. The first handle 10 is pulled outward in the axial direction, and the handle shaft 16 slides out. Different types of handles can be replaced. In actual applications, the arrangement method and number of the handle shaft 16 and the return spring positioning member 17 can also be changed according to actual needs, which are not specifically limited here.
[0025] Reference Figure 2-Figure 5 On the basis of the above embodiment, a fixed bushing 15 is provided at one end of the quick lock member 14, and the handle shaft 16 is assembled with the connecting shaft 13. The quick lock member 14 can rotate around the fixed bushing 15. The quick lock member 14 is rotated so that the quick lock member 14 does not block the handle shaft 16. The first handle 10 is pulled outward along the axial direction, and the handle shaft 16 slides out, so that different types of handles can be replaced.
[0026] Reference Figure 2-Figure 4 A flange 7 is provided on one side of the output end of the motor 6, and a protective sleeve 8 is provided on one side of the flange 7. The protective sleeve 8 is connected to the right mounting crank 9. The right mounting crank 9 is installed through the flange 7 to improve the overall connection effect of the device.
[0027] Reference Figure 3-Figure 5 The fixed end of the quick lock member 14 is fixed to the first handle 10 through the fixed bushing 15 and is assembled to rotate around the fixed bushing 15. The fixed end of the quick lock member 14 is fixed to the first handle 10 through the fixed bushing 15 and can rotate freely around the fixed bushing 15. The fixed bushing 15 fixed to the first handle 10 is used as a stopper for the rotating end of the quick lock member 14.
[0028] Reference Figure 3-Figure 5 The fixed bushing 15, the quick lock 14, the handle shaft 16, the return spring positioning member 17 and the sleeve 18 together constitute a handle quick-change mechanism. The second handle 12 is provided with a quick-change mechanism with the same structure as the first handle 10. The quick-change mechanism is formed by multiple components to improve the convenience of removing and replacing the handle of the device and improve the overall use effect of the device.
[0029] Reference Figure 4-Figure 5 The quick-change mechanism is coaxially connected to the connecting shaft 13, the handle shaft 16 and the shaft sleeve 18 are assembled with their axes coincident, and the shaft sleeve 18 is coaxially assembled inside the first handle 10. The coaxial assembly can reduce energy loss and reduce friction between rotating parts, thereby improving the efficiency of the mechanical system.
[0030] Working principle: the return spring positioning member 17 is fixed in the cavity of the first handle 10, the fixed end of the quick lock member 14 is fixed to the first handle 10 through the fixed bushing 15 and can rotate freely around the fixed bushing 15, and the fixed bushing 15 fixed to the first handle 10 is used as a stopper for the rotating end of the quick lock member 14. When the rotating end of the quick lock member 14 rotates to the fixed bushing 15, it cannot continue to rotate. At this time, the quick lock member 14 is positioned by the return spring positioning member 17 fixed in the cavity of the first handle 10. After the quick lock member 14 is positioned by the return spring positioning member 17, the inner surface of the quick lock member 14 can block the handle shaft 16 to prevent the handle shaft 16 from rotating axially. By sliding out, use your fingers to slightly apply force to push the quick-locking member 14, the return spring positioning member 17 is compressed after being stressed, and no longer positions the quick-locking member 14, and the quick-locking member 14 can rotate around the fixed bushing 15, and the quick-locking member 14 is rotated so that the quick-locking member 14 no longer blocks the handle shaft 16, and the first handle 10 is pulled outward along the axial direction, and the handle shaft 16 slides out, and different types of handles can be replaced. The quick-change mechanism is coaxially connected to the connecting shaft 13, and the axes of the handle shaft 16 and the shaft sleeve 18 are coincident for assembly, and the shaft sleeve 18 is coaxially assembled inside the first handle 10. The coaxial assembly can reduce energy loss and reduce the friction between rotating parts, thereby improving the efficiency of the mechanical system.
