Abstract
Description
Technical Field
[0001] This utility model relates to the field of leg care walking aids, and more specifically, it relates to a leg care walking aid. Background Technology
[0002] In the current technological landscape, leg support walkers are assistive devices designed for people who need extra support to walk. However, existing walkers have some design limitations that affect their efficiency and convenience.
[0003] First, many existing leg care walkers use a fixed height design. This design does not take into account the height differences between users, and therefore cannot provide flexible adaptation for users of different heights. For taller users, a walker that is too low may require them to bend over or bend their knees to walk, which is not only uncomfortable, but may also put extra pressure on the lower back and knee joints. For shorter users, a walker that is too high may prevent them from fully utilizing the support function of the walker, increasing inconvenience and safety hazards.
[0004] Secondly, although some existing technologies attempt to achieve height adjustment of walking aids through certain mechanisms, these adjustment mechanisms are often too simple in structure. Such simple structural design cannot guarantee stability and sturdiness after adjustment, and the structure is prone to loosening during use, affecting the stability and safety of the walking aid. This instability may cause accidents when the user is walking, especially when greater support is required.
[0005] In addition, existing walking aids are usually simple in structure and often require users to manually move the device to achieve the walking function. This design may pose a great challenge to people with weak leg support, who may not have enough strength or coordination to operate these devices effectively, resulting in them not being able to make full use of the walking aid's support, thus limiting their mobility and quality of life.

[0031] Please see Figure 1-5A leg care walking aid includes a support 1, characterized in that: a walking aid device is provided on the support 1, and an adjustment device is provided above the support 1. The adjustment device includes a telescopic rod 2, a mating groove 3, a mating block 4, a spiral groove 5, an adjustment sleeve 6, a fixed sleeve 7, a sliding groove 8, a mating plate 40, a ball bearing 9, and a sliding sleeve 10. The telescopic rod 2 is movably disposed inside the fixed sleeve 7. The mating groove 3 is opened inside the fixed sleeve 7. The mating block 4 is connected to one side of the mating plate 40. The spiral groove 5 is opened inside the adjustment sleeve 6. The adjustment sleeve 6 is movably sleeved on the outside of the fixed sleeve 7. The fixed sleeve 7 is fixedly installed on the support 1. The sliding groove 8 is opened on the side wall of the fixed sleeve 7. The ball bearing 9 is rolled on the outside of the sliding sleeve 10, and the sliding sleeve 10 slides. The telescopic rod 2 is set inside the fixed sleeve 7 and has a limiting mechanism on its outer side. The limiting mechanism includes an adapter groove 11, an outer threaded sleeve 12, an inner threaded sleeve 13, a rotating sleeve 14, an adapter 15, an adapter plate 16, an adapter rod 17, and a push spring 18. The adapter groove 11 is opened on one side of the adjusting sleeve 6. The outer threaded sleeve 12 is fixedly set on one side of the adapter 15. The inner threaded sleeve 13 is fixedly connected to one side of the rotating sleeve 14. Both the outer side of the outer threaded sleeve 12 and the inner side of the inner threaded sleeve 13 are provided with threads. The rotating sleeve 14 is movably sleeved on the outside of the fixed sleeve 7. The adapter 15 is sleeved on the outside of the fixed sleeve 7. The adapter plate 16 is fixedly set on the outside of the adapter rod 17. The adapter rod 17 is fixedly connected to one side of the adapter 15. The push spring 18 is movably sleeved on the outside of the adapter rod 17.
[0032] A spring 19 is provided on one side of the mating block 4, and a pressure plate 20 is connected to the other end of the spring 19.
[0033] A connecting block 21 is provided on one side of the mating block 4, and a connecting groove 22 is provided on the sliding sleeve 10. The connecting block 21 is slidably designed in the connecting groove 22.
[0034] In this embodiment, when the device height needs to be adjusted according to the patient's height, the adapter 15 is first pushed, causing the adapter 15 to move the adapter rod 17 and the adapter plate 16. Then, one end of the adapter rod 17 will disengage from the adapter groove 11, and the adapter plate 16 will cooperate with the rotating sleeve 14 to compress the push spring 18 sleeved on the outside of the adapter rod 17. Then, the inner threaded sleeve 13 and the outer threaded sleeve 12 will come into contact. Then, the rotating sleeve 14 will be rotated in the corresponding direction, and the rotating sleeve 14 will drive the inner threaded sleeve 13 to rotate, so that the outer threaded sleeve 12 will be gradually tightened to the inner side of the inner thread through the thread, thereby adjusting the adapter. The sleeve 15 is limited, and then the adjusting sleeve 6 is rotated in the corresponding direction. The adjusting sleeve 6 will drive the inner spiral groove 5 to rotate. Due to the special structural design of the spiral groove 5 and the rolling ball 9 rolling in the spiral groove 5, and due to the limiting of the sliding sleeve 10 by the sliding groove 8, the rotation of the threaded groove will cause the sliding sleeve 10 to slide along the sliding groove 8 inside the fixed sleeve 7. Then the sliding sleeve 10 will drive the mating block 4 to slide through the connecting block 21 and the connecting groove 22. Then the mating block 4 will drive the mating plate 40 to slide along the mating groove 3. Due to the inclination of the mating groove 3 and the mating plate 40, The inclined structure design allows the mating plate 40 to slide along the mating groove 3, causing the mating block 4 to expand outwards. Simultaneously, the mating block 4 causes the connecting block 21 to slide along the connecting groove 22. Then, the mating block 4 causes the spring 19 to gradually return to its original position. The spring 19 then causes the pressure plate 20 to stop pressing against the side wall of the telescopic rod 2. The movable frame 23 can then be pushed upwards or pressed downwards, causing it to move the telescopic rod 2. After adjusting to the appropriate height, the adjusting sleeve 6 is rotated in the opposite direction, allowing the adjusting sleeve 6 to move through the engagement of the threaded groove and the ball bearing 9. The moving sleeve 10 resets, and then the sliding sleeve 10 drives the mating block 4 to reset, so that the mating block 4, through the spring 19, drives the pressure plate 20 to clamp the side wall of the telescopic rod 2 again, preventing the telescopic rod 2 from moving. Then, the rotating adjusting sleeve 6 stops rotating, and then the rotating sleeve 14 rotates in the opposite direction. The rotating sleeve 14 drives the inner threaded sleeve 13 to rotate, so that the outer threaded sleeve 12 is gradually screwed out of the inner threaded sleeve 13. Then, the push spring 18 pushes the adapter plate 16 and the adapter rod 17 to reset, so that the adapter rod 17 is inserted into the corresponding adapter groove 11, thereby avoiding unnecessary rotation of the adjusting sleeve 6 and ensuring the stability of the structure.
[0035] Please see Figure 1 As one embodiment of the walking aid device: the walking aid device includes a movable frame 23 and a handle 24. The movable frame 23 is connected above the telescopic rod 2, and the handle 24 is detachably installed on one side of the movable frame 23.
[0036] A cushion 25 is provided on one side of the handle 24, and the cushion 25 can be detachably installed above the movable frame 23.
[0037] The movable frame 23 is detachably equipped with a mounting frame 26, and the mounting frame 26 is detachably equipped with a seat cushion 27.
[0038] A backrest 28 is connected to one side of the seat cushion 27.
[0039] The bottom of the bracket 1 is equipped with casters 29, and multiple casters 29 can be movably installed at the four corners of the bottom of the bracket 1.
[0040] More specifically, when a patient with weak leg support needs to use the device, the patient first stands inside the device. Then, medical staff detachably install the mounting frame 26 onto the movable frame 23 using bolts. Next, the seat cushion 27 is detachably installed onto the mounting frame 26. The device height is then adjusted to suit the patient, who can then sit on the seat cushion 27, hold the handle 24, and slowly push the device with their legs. The device moves via the casters 29. The backrest 28 supports the patient's back, preventing them from falling backward and improving comfort. When a patient with relatively strong leg support needs to use the device, the mounting frame 26 and seat cushion 27 are removed. The patient can then hold the handle 24 with both hands, and their elbows and upper body can be supported on the backrest 25. The backrest 25 improves the device's comfort. The patient then slowly moves the device by moving their legs, allowing it to move flexibly via the casters 29.
[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the equipment height according to the patient's height, first push the adapter 15, causing the adapter 15 to move the adapter rod 17 and the adapter plate 16. Then, one end of the adapter rod 17 will disengage from the adapter groove 11, and the adapter plate 16 will cooperate with the rotating sleeve 14 to compress the push spring 18 sleeved on the outside of the adapter rod 17. Then, the inner threaded sleeve 13 and the outer threaded sleeve 12 will come into contact. Then, rotate the rotating sleeve 14 in the corresponding direction, and the rotating sleeve 14 will drive the inner threaded sleeve 13 to rotate, so that the outer threaded sleeve 12 is gradually tightened into the inner thread through the thread. The adjusting sleeve 6 is rotated in the corresponding direction to limit the movement of the matching sleeve 15. The adjusting sleeve 6 will drive the inner spiral groove 5 to rotate. Due to the special structural design of the spiral groove 5 and the rolling ball 9 rolling in the spiral groove 5, and the limiting of the sliding sleeve 10 by the sliding groove 8, the rotation of the threaded groove will cause the sliding sleeve 10 to slide along the sliding groove 8 inside the fixed sleeve 7. Then the sliding sleeve 10 will drive the mating block 4 to slide through the connecting block 21 and the connecting groove 22. Then the mating block 4 will drive the mating plate 40 to slide along the mating groove 3. Due to the mating groove 3 and the mating plate The inclined structure design of plate 40 allows it to slide along the mating groove 3, causing the mating block 4 to expand outwards. Simultaneously, the mating block 4 causes the connecting block 21 to slide along the connecting groove 22. Then, the mating block 4 causes the spring 19 to gradually return to its original position. The spring 19 then causes the pressure plate 20 to stop pressing against the side wall of the telescopic rod 2. The movable frame 23 is then pushed upwards or pressed downwards, causing it to move the telescopic rod 2. After adjusting to the appropriate height, the adjusting sleeve 6 is rotated in the opposite direction, allowing it to pass through the threaded groove and the mating band of the ball bearing 9. The sliding sleeve 10 is reset, and then the sliding sleeve 10 drives the mating block 4 to reset, so that the mating block 4 drives the pressure plate 20 through the spring 19 to clamp the side wall of the telescopic rod 2 again to prevent the telescopic rod 2 from moving. Then the rotation of the adjusting sleeve 6 is stopped, and then the rotating sleeve 14 is rotated in the opposite direction. The rotating sleeve 14 drives the inner threaded sleeve 13 to rotate, so that the outer threaded sleeve 12 is gradually screwed out of the inner threaded sleeve 13. Then the push spring 18 pushes the adapter plate 16 and the adapter rod 17 to reset, so that the adapter rod 17 is inserted into the corresponding adapter groove 11, thereby avoiding unnecessary rotation of the adjusting sleeve 6 and ensuring the stability of the structure.
[0042] When a patient with weak leg support needs to use the device, the patient first stands inside the device. Then, the medical staff detachably installs the mounting frame 26 onto the movable frame 23 using bolts. Next, the seat cushion 27 is detachably installed onto the mounting frame 26. The device height is then adjusted to suit the patient. The patient can then sit on the seat cushion 27, hold the handle 24, and slowly push the device with their legs, allowing it to move via the casters 29. The backrest 28 supports the patient's back, preventing them from falling backward and improving comfort. When a patient with relatively strong leg support needs to use the device, the mounting frame 26 and seat cushion 27 are removed. The patient can then hold the handle 24 with both hands, and their elbows and upper body can be supported on the backrest 25. The backrest 25 improves the device's comfort. The patient then slowly moves their legs to push the device, allowing it to move flexibly via the casters 29.
