DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0028] Embodiment 1
[0029] Refer to Figures 1 - 5 , a walking aid device, comprising: two frames 1 and two crutch mechanisms. At the top of each of the two frames 1, a first mounting tube 2 is fixedly connected for supporting and mounting the crutch mechanism. In the middle of each of the two frames 1, a second mounting tube 3 is fixedly connected for further fixing and supporting the crutch mechanism. Particularly, a fixing groove 14 is formed at the top of the second mounting tube 3 for cooperating with components in the crutch mechanism to achieve stable sliding and resetting of the crutch body.
[0030] The crutch mechanism includes a crutch body 4. The crutch body 4 slidably penetrates through the circumferential outer walls of the first mounting tube 2 and the second mounting tube 3. This design allows the crutch body 4 to slide up and down within a certain range on the frame 1. On the circumferential outer wall of the crutch body 4, two limiting mounting plates 6 are fixedly connected in an up-and-down arrangement. These two limiting mounting plates 6 are respectively located at the upper and lower ends of the crutch body 4 for restricting the sliding range of the crutch body 4. A same spring 7 is fixedly connected between the fixing groove 14 and the bottom of the upper limiting mounting plate 6. The spring 7 is used to automatically reset the crutch body 4 to its initial position after the crutch body 4 is acted upon by an external force.
[0031] At the top of the crutch body 4, an elbow rest 5 is fixedly connected for supporting the user's arm. At the bottom of the crutch body 4, an anti-slip foot sleeve 8 is fixedly connected to increase the friction between the crutch body 4 and the ground and prevent slipping.
[0032] In the middle of each of the two frames 1, a third mounting tube 21 is fixedly connected. On the circumferential outer wall of the third mounting tube 21, two fixing blocks 16 are rotatably connected. On one side of the two fixing blocks 16, a same seat plate 13 is fixedly connected. A sliding groove 17 is formed at the bottom of the seat plate 13. A rotating groove 15 is formed on the circumferential outer wall of the second mounting tube 3. A support rod 18 is rotatably connected in the rotating groove 15. On both sides of one end of the support rod 18, two pulleys 19 are fixedly connected. The two pulleys 19 are slidably connected with the sliding groove 17. This design allows the seat plate 13 to rotate on the third mounting tube 21, and at the same time, the support rod 18 and the pulleys 19 slide in the rotating groove 15 and the sliding groove 17, thereby achieving stable support and adjustment of the seat plate 13.
[0033] On the top of one side of the two frames 1 close to each other, a same armrest 11 is fixedly connected. At both ends of the armrest 11, two handles 12 are fixedly connected. This design allows the user to place the hand on the armrest 11 when walking to increase stability. At the same time, the user can also push the walking aid device forward or backward by grasping the handles 12.
[0034] At the bottom of both of the two frames 1, a universal wheel 9 and a fixed caster 10 are respectively fixedly connected. The universal wheel 9 allows the walking aid device to turn and move flexibly when walking, while the fixed caster 10 is used to ensure the stability of the walking aid device when walking in a straight line. This design makes the walking aid device both convenient and practical, as well as safe and stable.
[0035] This application can be used in the field of orthopedic rehabilitation, and can also be used in other fields applicable to this application.
[0036] Embodiment 2
[0037] Reference Figures 1 - 5 , on the basis of Embodiment 1, an improvement is made: for a walking aid device, in order to fix the seat plate 13, at the top of both of the two seat plates 13, fixing straps 20 for fixing are fixedly connected. Users can fix the seat plate 13 on the frame 1 through the fixing straps 20 to prevent the seat plate 13 from opening during walking and causing trouble to the user;
[0038] In order to further improve the stability and safety of the walking aid device, the two frames 1 form an angle of 65° with the ground, and the two crutch bodies 4 also form an angle of 65° with the ground. This design makes the walking aid device more stable during use, prevents the user from tipping over due to uneven force on both sides, and reduces the risk of the user falling.
