[0029] See also Figures 1 to 5 , shown is a limb function rehabilitation training device for the elderly in an embodiment of the present utility model, including an instrument frame, the instrument frame including an armrest 10, and a moving mechanism, the moving mechanism including a front walking wheel 50 and a rear walking wheel 60, the limb function rehabilitation training device for the elderly also includes an upper limb exercise mechanism and a self-locking mechanism, the upper limb exercise mechanism includes a counterweight assembly 20 sliding along the armrest 10, the self-locking mechanism includes a first rotating shaft 30 located on the instrument frame, a first winding wheel 31 fixed to the first rotating shaft 30, a second winding wheel 32 fixed to the first rotating shaft 30, and a plurality of winding wheels 31 and 32 respectively arranged on the front walking wheel 50 and the rear walking wheel 60. The two self-locking components 40 at the rear traveling wheel 60, the counterweight component 20 is fixedly connected to a first pull wire 24, the other end of the first pull wire 24 is connected to the first winding wheel 31, and the second winding wheel 32 is fixedly connected to a second pull wire 33, and the two ends of the second pull wire 33 are respectively connected to the two self-locking components 40, pushing the counterweight component 20, the first pull wire 24 drives the first winding wheel 31 to rotate together with the first rotating shaft 30, and the rotation of the first rotating shaft 30 drives the second winding wheel 32 to rotate, so that the second pull wire 33 drives the two self-locking mechanisms to lock the front traveling wheel 50 and the rear traveling wheel 60.

[0030] When the weight assembly 20 is pulled back, the center of gravity of the elderly is restored, and the moving mechanism of the elderly limb function rehabilitation training device is not caused to move.

[0031] The utility model allows the elderly to fully train their healthy upper limbs in their spare time when using the device for lower limb rehabilitation, thereby improving time utilization.

[0032] Specifically, in this embodiment, a cavity is provided inside the armrest 10, and the counterweight assembly 20 includes a counterweight block 21 slidingly connected to the cavity, and a handle 22 fixedly connected to the counterweight block 21, and the handle 22 is located on the upper surface of the armrest 10. A blocking plate is also provided inside the cavity, and the blocking plate is used to limit the displacement of the counterweight block 21.

[0033] It can be understood that the counterweight 21 is placed in the cavity inside the armrest 10, and then the handle 22 is connected to the counterweight 21, wherein the handle 22 protrudes from the upper surface of the armrest 10. The elderly can hold the handle 22 to push or pull back the counterweight 21 to exercise the biceps and triceps. A blocking plate is provided near the rear of the cavity. When the counterweight 21 contacts the blocking plate, the self-locking assembly 40 is in an unlocked state.

[0034] Specifically, the mobile mechanism further includes a front wheel frame 51 and a rear wheel frame 61, the front running wheel 50 is mounted on the front wheel frame 51, and the rear running wheel 60 is mounted on the rear wheel frame 61; a first bearing seat 52 and a second bearing seat 62 are respectively mounted on the front wheel frame 51 and the rear wheel frame 61, and the first bearing seat 52 and the second bearing seat 62 are respectively connected to the self-locking assembly 40 at the front running wheel 50 and the rear running wheel 60;

[0035] In this embodiment, the self-locking assembly 40 includes a second rotating shaft 41 located on the first bearing seat 52 or the second bearing seat 62, a third winding wheel 42 installed on the second rotating shaft 41, a slotted plate 43 fixed to the second rotating shaft 41, and a locking plate 44 rotatably connected to the second rotating shaft 41, wherein the locking plate 44 is fixedly connected to the first bearing seat 52 or the second bearing seat 62, and a plurality of arc grooves 431 are formed through the slotted plate 43, and a plurality of sliding grooves 441 are formed on the locking plate 44, and a plurality of locking structures 45 slide along the sliding grooves 441. The locking structure 45 includes a connecting rod 451 located in both the arc groove 431 and the sliding groove 441, and a locking rod fixedly connected to the connecting rod 451, and the rotation of the slotted plate 43 drives the connecting rod 451 and the locking rod to slide along the sliding groove 441, so that the locking rod is in close contact with the tire of the front walking wheel 50 or the rear walking wheel 60.

[0036] It should be noted that, in other embodiments, other locking assemblies may be used to fix the tire, which is not difficult for mechanical engineers.

[0037] It can be understood that when the second winding wheel 32 rotates, it will drive the two ends of the second pull wire 33 thereon to be tightened, so that the third winding wheel 42 at the front walking wheel 50 and the rear walking wheel 60 will rotate at the same time, driving the second rotating shaft 41 to rotate. The rotation of the second rotating shaft 41 will drive the slot plate 43 to rotate. Since the two ends of the arc groove 431 on the slot plate 43 are respectively located at different radii of the slot plate 43, when the slot plate 43 rotates, the connecting rod 451 will move from the arc groove 431 at the small radius end of the slot plate 43 to the large radius end, so that the connecting rod 451 carries the locking rod along the slide groove 441 from the inside to the outside of the locking plate 44 until it clamps the inner tube wall of the front walking wheel 50 and the rear walking wheel 60 to lock the tire, wherein the second rotating shaft 41 rotates on the first bearing seat 52 and the second bearing seat 62, and the locking plate 44 is also installed on the bearing seat.

[0038] Furthermore, a spiral spring 34 is provided between the first rotating shaft 30 and the instrument frame. When the first pulling wire 24 is loosened, the spiral spring 34 is reset, thereby driving the first rotating shaft 30 to reset.

[0039] It can be understood that when the elderly push the counterweight 21 through the handle 22, the first pull wire 24 will be driven to make the first winding wheel 31 and the first rotating shaft 30 rotate at the same time. At this time, the spiral spring 34 is deformed. Since the force of the counterweight 21 is greater than the elastic force of the spiral spring 34, the spiral spring 34 will not reset. When the elderly pull back the counterweight 21 through the handle 22, the first rotating shaft 30 will return to its original position due to the reset force of the spiral spring 34, so as to drive the first winding wheel 31 to rotate, and then partially retract the first pull wire 24 into the first winding wheel 31.

[0040] Furthermore, a torsion spring 46 is provided between the second rotating shaft 41 and the first bearing seat 52 or the second bearing seat 62 , and the second pull wire 33 is relaxed so that the torsion spring 46 drives the second rotating shaft 41 to reset.

[0041] It can be understood that when the second winding wheel 32 rotates to drive the second pull wire 33 to pull the third winding wheel 42, causing the second rotating shaft 41 to rotate, the torsion spring 46 is deformed. Since the force of the counterweight block 21 is greater than the elastic force of the torsion spring 46, the torsion spring 46 will not reset. When the second winding wheel 32 returns to its original position due to the action of the vortex spring 34, the second pull wire 33 no longer pulls the third winding wheel 42. At this time, the second rotating shaft 41 together with the third winding wheel 42 will return to their original position due to the reset force of the torsion spring 46.

[0042] By disposing the spiral spring 34 and the torsion spring 46 , the upper limb exercise mechanism and the self-locking mechanism can work together.

[0043] Furthermore, a tensioning wheel 23 is provided at the end of the handrail 10 , and the tensioning wheel 23 is used to tension the first pull wire 24 .

[0044] It can be understood that by providing the tensioning wheel 23 , the movement of the first pull wire 24 is smoother when the counterweight 21 is pushed or pulled back.

[0045] Furthermore, the locking rod includes a connecting portion 452 fixedly connected to the connecting rod 451, an abutting portion 453 located on the side of the connecting portion 452 close to the tire of the front running wheel 50 or the rear running wheel 60, and a spring 454 connecting the connecting portion 452 and the abutting portion 453.

[0046] It is understandable that after the abutting portion 453 contacts the sidewall of the tire, the abutting portion 453 continues to extend in the direction of the tire to squeeze the spring 454, so that the abutting portion 453 does not damage the tire while contacting the sidewall more closely, thereby locking the tire better.

[0047] It should be noted that when the electric lift is transformed into a standing form, the distance between the counterweight 21 and the first winding wheel 31 will increase, but it will only cause the first pull wire 24 on the first winding wheel 31 to be slightly stretched. The stretching of the first pull wire 24 will not cause the tire to be directly locked, thereby affecting the normal use of the device.

[0048] In summary, the limb function rehabilitation training device for the elderly in the above-mentioned embodiment of the present invention, by arranging a counterweight assembly sliding along the armrest at the armrest, the elderly can push and pull the counterweight assembly back and forth in their spare time to exercise their arm muscles. When pushing the counterweight assembly, the center of gravity will be caused to move forward, which makes it easy for the mobile mechanism of the limb function rehabilitation training device for the elderly to move. Therefore, by arranging a self-locking mechanism, when the counterweight assembly is pushed, it will drive the first pull wire to pull the first winding wheel to rotate, and the rotation of the first winding wheel will drive the first rotating shaft to rotate, and the rotation of the first rotating shaft will drive the second winding wheel to rotate, so that the pull wire on the second winding wheel will synchronously pull the self-locking assembly at the front and rear traveling wheels, so that the self-locking assembly is locked into the tires of the front and rear traveling wheels to prevent movement during exercise. When the counterweight assembly is pulled back, the center of gravity of the elderly is restored and the mobile mechanism will not move, so there is no need to lock the tires.

[0049] The utility model allows the elderly to fully train their healthy upper limbs in their spare time when using the device for lower limb rehabilitation, thereby improving time utilization.
