DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3A passive motion rehabilitation device for finger joints shown in the figure includes a controller 1, the output end of the controller 1 is electrically connected to a connecting plug 2, a transmission line 3 is arranged on the front of the connecting plug 2, a rehabilitation glove 4 is arranged on the end of the transmission line 3 away from the connecting plug 2, a fixing seat 5 is fixedly connected to one side of the controller 1, a fixing block 6 is fixedly connected to the top of the connecting plug 2, a positioning groove 7 for accommodating the fixing block 6 is provided at the bottom end of the fixing seat 5, a card slot 8 is provided on one side of the fixing block 6, a card block 9 for limiting the movement of the fixing block 6 is carded inside the card slot 8, a moving part for moving the card block 9 is arranged on one side of the card block 9, the fixing block 6 is inserted and connected inside the positioning groove 7, a through hole is provided on the inner wall of one side of the positioning groove 7, and the card block 9 is inserted and connected inside the through hole.

[0020] It should be noted that the controller 1, connecting plug 2, transmission line 3 and rehabilitation gloves 4 are hand function training equipment with model HRR-08. A transmission line is set on one side of the controller 1, and the controller 1 is powered by the transmission line; the fixed seat 5 is fixed on the front of the controller 1 and is located on the top of the connecting plug 2. When the connecting plug 2 is inserted into the output end of the controller 1, the fixing block 6 at the top of the connecting plug 2 is inserted into the interior of the positioning groove 7 opened at the bottom end of the fixing seat 5, and is inserted into the interior of the card slot 8 opened on one side of the fixing block 6 by inserting the card block 9 connected to the inner wall of one side of the positioning groove 7. The fixing block 6 is restricted from passing out of the positioning groove 7 by the card block 9, so that the position of the fixing block 6 is fixed, and the position of the connecting plug 2 and one end of the transmission line 3 is fixed by the fixed block 6 at the fixed position.

[0021] Specifically, a cavity 10 is provided on one side of the fixed seat 5, and the movable member includes a connecting plate 11 inserted and connected inside the cavity 10, the connecting plate 11 is sleeved in the middle of the card block 9, and an elastic block 12 is provided on one side of the connecting plate 11, the elastic block 12 is sleeved in the middle of the card block 9, and the elastic block 12 is fixedly connected to the inner wall of one side of the cavity 10. The movable member also includes a driving block 13 fixedly connected to one end of the card block 9, the top of the driving block 13 is fixedly connected to a moving block 14, and the top of the moving block 14 is provided with a pushing groove 16. A storage groove 15 is provided on one side of the fixed seat 5, and the driving block 13 is inserted and connected inside the storage groove 15.

[0022] It should be noted that the cavity 10 is used to accommodate the connecting plate 11 and the elastic block 12; the through hole is used to connect the cavity 10 and the positioning groove 7, and when in use, it is used to move the end of the card block 9 into and out of the positioning groove 7 through the through hole; the cavity 10 is adapted to be provided with the connecting plate 11, and when in use, the connecting plate 11 is used to slide inside the cavity 10, and the connecting plate 11 is fixedly sleeved in the middle of the card block 9. When in use, the connecting plate 11 is driven to move by the card block 9, and the card block 9 can also be driven to move by the connecting plate 11. The elastic block 12 is made of rubber material, which has a deformable property. It will deform when squeezed, and will recover when the squeezing force is lost. The driving block 13 is used to connect the card block 9 and the moving block 14. The moving block 14 arranged at the top of the fixed seat 5 drives the card block 9 located in the cavity 10 to move. A driving push groove 16 is provided at the top of the moving block 14 for pressing a finger. The pushing groove 16 is used to increase the friction between the finger and the top of the moving block 14 to avoid the situation where the moving block 14 cannot be pushed due to hand slippage.

[0023] Furthermore, when it is necessary to fix the position of the connecting plug 2, the moving block 14 is first pushed toward one side of the driving block 13, and the driving block 13 and the card block 9 are driven by the moving block 14, so that the end of the card block 9 moves out of the positioning groove 7, and the card block 9 drives the connecting plate 11 to squeeze the elastic block 12, so that the elastic block 12 is deformed, and then the connecting plug 2 is inserted into the output end of the controller 1, and the fixing block 6 is driven by the connecting plug 2 to move into the interior of the positioning groove 7. When the card slot 8 opened on the fixed block 6 is aligned with the set card block 9, the push on the moving block 14 is released, and the elastic block 12 recovers the deformation, and the connecting plate 11 is pushed toward one side of the fixed block 6, and the end of the card block 9 is driven by the connecting plate 11 to move into the interior of the card slot 8, so that the fixed block 6 is restricted by the card block 9 and cannot move, and the position of the connecting plug 2 is fixed by the fixed block 6 in a fixed position.

[0024] Specifically, a slider 17 is fixedly connected to the bottom end of the moving block 14, a slide groove 18 is provided at the top end of the fixed seat 5, and the slider 17 is slidably inserted into the inside of the slide groove 18, and the cross-sections of the slider 17 and the slide groove 18 are both set to be convex.

[0025] It should be noted that the convex slider 17 and the slide groove 18 are set to prevent the slider 17 from sliding out of the slide groove 18 when in use, so that the slider 17 moves along the direction of the slide groove 18 when moving. When the slider 17 moves in the same direction, when it moves to fit with the inner wall of the slide groove 18, it will be unable to move the slider 17 further. The slide groove 18 is used to limit the moving distance of the slider 17. When in use, the slider 17 that limits the moving direction is used to limit the moving direction and moving distance of the moving block 14 fixedly connected to it.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
