CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at solving the problems in the prior art and provides an exercise device for old people's rehabilitation nursing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] An exercise device for old people's rehabilitation nursing comprises a vehicle body for assisting walking, two parallel support seats are fixedly connected to the vehicle body, support rods (4) are slidably inserted into the two support seats, a front guard rod is fixedly connected between the two support rods, a connecting rod is fixedly connected below the front guard rod, a seat and a rear guard rod are respectively installed on the connecting rod, and the seat is arranged on the connecting rod.

[0007] The support rods can move up and down along the height direction of the support seats, an auxiliary frame is hingedly installed between the two support rods, a linkage rod is installed between the auxiliary frame and the vehicle body, and a locking mechanism that can lock the auxiliary frame and the vehicle body is arranged between the vehicle body and the auxiliary frame.

[0008] In the locked state, the locking mechanism is locked with the vehicle body, and in the unlocked state, the locking mechanism is unlocked with the vehicle body.

[0009] Preferably, the vehicle body includes two parallel crossbars, each end of which is equipped with a traveling wheel and a swivel wheel, respectively. A longitudinal bar is fixedly connected between the two crossbars, and two support seats are fixedly connected to the two crossbars. A support plate is fixedly connected to the side of each crossbar, and one end of the linkage rod is hinged to the support plate, while the other end of the linkage rod is hinged to the auxiliary frame.

[0010] Preferably, the locking mechanism includes a collar fixedly connected to an auxiliary frame, a screw fixedly connected to one side of the collar, a butterfly threadedly connected to the screw, a receiving groove on the longitudinal rod, the screw movable into the receiving groove, a mating groove on the screw, a groove at the end of the screw, a clamp hinged in the groove by a pin, a half-stud movable into the mating groove fixedly connected to the end of the clamp away from the groove, and the butterfly threadedly connected to the screw and the half-stud to achieve locking.

[0017] 1. This application features a dual-mode system with free switching between the two modes. A locking mechanism enables rapid switching between "walking mode" and "squatting mode". In walking mode, the support rod height is locked, and the front guard bar provides stable support to assist the elderly in walking safely and to achieve walking exercise. In squatting mode, the support rod is raised and lowered in linkage, and the linkage rod transmits the movement trajectory to assist the elderly in squatting training and help the lower limb muscle strength recovery. It meets diverse needs such as postoperative rehabilitation, muscle weakness, and balance training, and replaces traditional single-function equipment.

[0018] 2. In this application, when the rear guard bar is unfolded into a vertical backrest, the insert bar automatically engages with the locking teeth via a spring to prevent backward tilting and loss of control. The front guard bar and the support bar form a rigid frame to reduce the risk of forward tilting. The linear array of through holes in the adjustment rod adapts to different height ranges, improving the comfort of sitting training. When tired from exercise or when there is insufficient hand support, one can sit directly on the seat to rest, avoiding accidents. Attached Figure Description

The linear array through holes 62 on the adjusting rod 61 support multi-level height adjustment, and the height of the seat 6 is adjustable to adapt to users of different heights.

[0042] In this embodiment, a connecting box 11 is fixedly connected to the end of the connecting rod 5. A support shaft 12 is fixedly connected inside the connecting box 11. A locking tooth 13 is rotatably provided on the support shaft 12. The rear guard rod 7 is fixedly connected to the locking tooth 13. A limiting component 14 is installed at the bottom of the connecting box 11. The limiting component 14 includes a vertical cylinder 141 fixedly connected to and communicating with the connecting box 11. A slip ring 142 is slidably provided inside the vertical cylinder 141. An insert rod 143 is fixedly connected to the inner side of the slip ring 142. One end of the insert rod 143 can extend into the connecting box 11 and engage with the locking tooth 13. The other end of the insert rod 143 extends to the bottom of the vertical cylinder 141. A spring 144 is fixedly connected between the bottom of the slip ring 142 and the inner wall of the vertical cylinder 141. A through groove 111 is provided on the connecting box 11. The rear guard rod 7 passes through the through groove 111. The opening size of the through groove 111 allows the rear guard rod 7 to rotate 90°.

[0043] Specifically, by pulling the insert rod 143, the slip ring 142 slides and squeezes the spring 144, the insert rod 143 and the locking tooth 13 separate, and the rear guard rod 7 rotates 90° around the support shaft 12 to a vertical state through the locking tooth 13. The insert rod 143 of the limiting component 14 is locked into the locking tooth 13 under the action of the spring 144, locking the angle of the rear guard rod 7. The rear guard rod 7 can be unfolded into a backrest or folded up to prevent backward fall.

[0045] Specifically, when the support rod 4 moves, it causes the limiting block 41 to slide up and down along the limiting groove 31 of the support base 3, limiting the range of movement, constraining the stroke of the support rod 4, and preventing excessive lifting and lowering from causing structural failure.

[0046] How to use and how to work this device:

[0047] In the locked state, i.e., walking mode, the screw 102 is inserted into the receiving groove 26 of the longitudinal rod 24, the rotating clamp 106 wraps around the longitudinal rod 24 and the half stud 107 enters the docking groove 104, the rotating butterfly 103 locks the half stud 107 and the screw 102 together, the auxiliary frame 8 is rigidly connected to the vehicle body 2, and the support rod 4 is height locked; crossing the seat 6 and the connecting rod 5, holding the front guard bar 1, the limit component 14 is released to adjust the rear guard bar 7 to a vertical state, the insertion rod 143 is engaged with the locking tooth 13 under the action of the spring 144 to form a backrest protection to prevent backward fall, the elderly hold the front guard bar 1, the vehicle body 2 moves flexibly through the universal wheels 23 and the walking wheels 22, the support rod 4 and the front guard bar 1 provide stable support to complete the walking exercise, when tired or the hand support is insufficient, they can sit directly on the seat 6 to rest to avoid accidents.

[0048] In the unlocked state, i.e. squatting mode, rotate the butterfly 103 in the opposite direction to separate the half stud 107 from the docking groove 104, and release the connection between the auxiliary frame 8 and the vehicle body 2. After the auxiliary frame 8 is unlocked, the support rod 4 can move up and down along the limiting groove 31 of the support seat 3. The linkage rod 9 transmits the movement trajectory. When the elderly sit on the seat 6, the elderly's family members or medical staff can press the auxiliary frame 8 to drive the support rod 4 to rise and fall, thus completing the squatting training.
