Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0033] Please refer to Figure 1 , the walking aid 100 according to the embodiment of the present application includes support legs 10, telescopic rods 20, a locking structure 30 and a pressing rod 40. A chamber is formed in the support legs 10 and a plurality of limiting holes 11 communicating with the chamber are provided; the telescopic rods 20 are slidably arranged in the support legs 10 along the axial direction of the support legs 10, and fixing holes 21 are provided on the side walls of the telescopic rods 20; the locking structure 30 is located in the support legs 10, and the locking structure 30 includes a clamping portion 31; the pressing rod 40 is movably arranged inside the telescopic rod 20 and is connected to the locking structure 30. When the pressing rod 40 is in the first position, the pressing rod 40 drives the locking structure 30 so that the clamping portion 31 at least partially penetrates into the fixing holes 21 and the limiting holes 11. When the pressing rod 40 is in the second position, the pressing rod 40 drives the locking structure 30 so that the clamping portion 31 withdraws from the limiting holes 11.

[0034] A walking aid 100 proposed by the embodiment of the present application, by arranging a telescopic rod 20 inside the support leg 10, when the pressing rod 40 is in the first position, the clamping portion 31 of the locking structure 30 disengages from the limiting hole 11 for height adjustment and rotates inward, so that the telescopic rod 20 can move inside the support leg 10, and thereby adjust the height of the walking aid 100. After adjusting to the required height, the pressing rod 40 is adjusted to the second position, so that the buckle rotates outward and enters the limiting hole 11 for height adjustment to fix the telescopic rod 20, thereby helping the user quickly and conveniently adjust the height of the walking aid 100, improving the effectiveness of the walking aid 100, and improving the comfort and convenience of the user when using.

[0035] The walking aid 100 is a device for assisting walking, suitable for patients and the elderly with lower limb functional impairments or mobility difficulties. The walking aid 100 can be divided into two types: non-wheeled and wheeled. Hereinafter, only the wheeled walking aid 100 will be taken as an example for illustration.

[0036] As an important support structure of the walking aid 100, the support leg 10 is usually designed as a central control filling with a circular or polygonal cross-section to ensure the structural strength of the walking aid 100 while reducing its weight. In this application, the support leg 10 is in the shape of a circular tube. Further, the telescopic rod 20 is also in the shape of a circular tube, and the outer diameter of the telescopic rod 20 is slightly smaller than the inner diameter of the support leg 10.

[0037] The locking structure 30 includes a connected locking arm 32 and a clamping portion 31. One end of the locking arm 32 is connected to the clamping portion 31, and the other end is connected to the pressing rod 40. In this embodiment, the locking arm 32 and the pressing rod 40 are rotatably connected. When the pressing rod 40 is pressed down, the clamping portion 31 is blocked by the fixing hole 21 and the limiting hole 11, causing the locking arm 32 to rotate towards the pressing rod 40. At this time, the locking arm 32 will drive the clamping portion 31 to disengage from the limiting hole 11, enabling the telescopic rod 20 to move inside the support leg 10. When the pressing rod 40 is pulled up, the locking arm 32 rotates away from the pressing rod 40 under the influence of gravity. At this time, the locking arm 32 will drive the clamping portion 31 to re-enter the limiting hole 11, fixing the telescopic rod 20. Preferably, the locking structure 30 further includes an elastic reset member. One end of the elastic reset member is connected to the locking arm 32, and the other end is connected to the pressing rod 40. The elastic reset member is used for the reset of the locking arm 32. Optionally, the elastic reset member can be a spring, a spring sheet or an elastic rubber block.

[0038] In other embodiments, the locking arm 32 and the pressing rod 40 can also be fixedly connected. At this time, the locking arm 32 is made of an elastic material. When the pressing rod 40 is pressed down, the clamping portion 31 is blocked by the fixing hole 21 and the limiting hole 11, and the locking arm 32 is compressed towards the pressing rod 40. At this time, the locking arm 32 will drive the clamping portion 31 to disengage from the limiting hole 11, enabling the telescopic rod 20 to move inside the support leg 10. When the pressing rod 40 is pulled up, the locking arm 32 is reset away from the pressing rod 40 under the influence of its own elastic force. At this time, the locking arm 32 will drive the clamping portion 31 to re-enter the limiting hole 11, fixing the telescopic rod 20. With this setting, there is no need to additionally set a reset elastic member in the locking structure 30.

[0039] Please refer to Figure 1, in some embodiments, the number of the clamping portions 31 is multiple, and the fixing holes 21 and the limiting holes 11 are arranged in one-to-one correspondence with the clamping portions 31. Specifically, the number of the locking arms 32 is the same as that of the clamping portions 31, and the clamping portions 31 and the locking arms 32 are arranged in one-to-one correspondence. The multiple clamping portions 31 can average the shearing force received by the clamping portions 31, greatly reducing the shearing force received by each clamping portion 31, improving the service life of the clamping portions 31, and at the same time making the telescopic rod 20 more firmly fixed, improving the reliability of the walking aid 100. In other embodiments, the number of the locking arms 32 and the number of the clamping portions 31 may also be different, and multiple clamping portions 31 may also be arranged on one locking arm 32 at the same time.

[0040] In some embodiments, the number of the clamping portions 31 is two, and the two clamping portions 31 are arranged back to back. Such an arrangement can reduce the complexity of the locking structure 30 while ensuring the service life of the clamping portions 31 and the reliability of the walking aid 100, facilitating the assembly of the walking aid 100, and at the same time reducing the cost of the walking aid 100. Specifically, the number of the locking arms 32 is the same as that of the clamping portions 31. Optionally, the ends of the two locking arms 32 away from the clamping portions 31 can be rotatably connected or fixedly connected. When the ends of the two locking arms 32 away from the clamping portions 31 are rotatably connected, the elastic reset member can be arranged between the two locking arms 32, and both ends of the elastic reset member are respectively connected to the two locking arms 32; when the ends of the two locking arms 32 away from the clamping portions 31 are fixedly connected, the two locking arms 32 are both made of elastic materials. Further, the locking structure 30 can be an integrally formed one-piece structure.

[0041] Please refer to Figure 3 and Figure 4 , in some embodiments, the walking aid 100 further includes a pressing handle 50, and a pressing portion 51 is arranged on the pressing handle 50. The pressing portion 51 is connected to the end of the pressing rod 40 away from the locking structure 30. Specifically, when the pressing handle 50 is pressed down, the pressing handle 50 will drive the pressing portion 51 to move downward and press the pressing rod 40, so that the locking structure 30 is unlocked. When the pressing handle 50 is lifted, the pressing handle 50 will drive the pressing portion 51 to move upward and lift the pressing rod 40, so that the locking structure 30 is locked. Compared with directly pressing or pulling the pressing rod 40, such an arrangement is more convenient for the user to operate, reduces the operation difficulty and improves the use comfort, which is beneficial to improving the user's use experience.

[0042] Please refer to Figure 1 and 2, in some embodiments, the walking aid 100 includes a fixing plate 22 and a first elastic member 23. The fixing plate 22 is located inside the telescopic rod 20. The pressing rod 40 passes through the fixing plate 22. The first elastic member 23 is sleeved on the pressing rod 40. One end of the first elastic member 23 is connected to the fixing plate 22, and the other end of the first elastic member 23 is connected to the pressing portion 51. With such a setting, the pressing handle 50 can be automatically reset, greatly reducing the operation difficulty of the walking aid 100 and improving the use comfort, which is beneficial to enhancing the user's experience. Specifically, the first elastic member 23 is a spring, which is sleeved on the pressing rod 40. The fixing plate 22 can be set in any shape. The fixing plate 22 can be fixedly arranged inside the telescopic rod 20 or detachably arranged inside the telescopic rod 20. In other embodiments, the fixing plate 22 can also be cancelled, and one end of the first elastic member 23 away from the pressing portion 51 can also be directly connected to the inner wall of the telescopic rod 20 through fasteners or the like.

[0043] Please refer to Figure 3 , in some embodiments, both the support legs 10 and the telescopic rods 20 include multiple ones. Each telescopic rod 20 is located inside one support leg 10. The walking aid 100 further includes a frame 60. The frame 60 is connected to multiple telescopic rods 20. The pressing handle 50 is slidably arranged on the frame 60 along the axial direction of the telescopic rod 20. Specifically, the frame 60 is in the shape of a "C"-shaped three-sided fence. The number of support legs 10 is four, and the telescopic rods 20 are arranged in one-to-one correspondence with the support legs 10. With such a setting, it can help the user maintain balance and prevent accidents such as falling during use. The three-sided fence can also provide a stable support surface, enabling the user to rely on the walking aid 100 better for walking. The three-sided fence can also prevent the user from veering off or hitting obstacles when using the walking aid 100.

[0044] Please refer to Figure 3 , in some embodiments, a limit fixing block 24 is further provided on the telescopic rod 20. The telescopic rod 20 is connected to the frame 60 through the limit fixing block 24. With such a setting, the limit fixing block 24 can prevent the frame 60 and the support feet from frequently colliding, causing damage or paint peeling of the support feet and the brackets. At the same time, it can also prevent the telescopic rod 20 from extending too far into the support feet, resulting in the telescopic rod 20 being unable to be pulled out or stuck. Specifically, the limit fixing block 24 is in the shape of a frustum of a cone. In other embodiments, the telescopic rod 20 can also be directly connected to the frame 60. The limit fixing block 24 is sleeved on the telescopic rod 20 and is arranged at the connection between the telescopic rod 20 and the frame 60.

[0045] Please refer to Figure 3, in some embodiments, the frame 60 includes a front beam 61 and two side beams 62. The two side beams 62 are connected to both ends of the front beam 61. The pressing handle 50 is slidably arranged on the side beam 62. Each side beam 62 is connected to two telescopic rods 20. The pressing handle 50 is provided with two pressing parts 51. The two pressing rods 40 arranged in the two telescopic rods 20 are arranged in one-to-one correspondence with the two pressing parts 51 of the pressing handle 50 on the side beam 62 connected to the two telescopic rods 20. Specifically, a sliding cavity is provided inside the side beam 62, and the pressing handle 50 is slidably arranged in the sliding cavity. When in use, the lower part of the side beam 62 and the upper part of the pressing handle 50 can be held by hand simultaneously to realize the operation of pressing down the pressing handle 50. With such an arrangement, one pressing handle 50 can control the telescoping of two telescopic rods 20 at the same time. When the pressing handle 50 is arranged on the side beams 62 on both sides, the side beam 62 can provide good leverage when using the pressing handle 50, making it more convenient to press the pressing handle 50.

[0046] Specifically, the walking aid 100 further includes a first reinforcing beam 63 and a second reinforcing beam 64. The first reinforcing beam 63 is connected to the support legs 10 corresponding to the two telescopic rods 20 connected to the same side beam 62. The second reinforcing beam 64 is connected to the two support legs 10 close to the front beam 61. A support block 65 is arranged on one side of the side beam 62 close to the other side beam 62. A handrail 66 is arranged on the support block 65, and a second anti-slip part 67 is arranged on the handrail 66. Optionally, the second anti-slip part 67 can be components such as anti-slip rubber and anti-slip latex, or anti-slip patterns arranged on the handrail 66.

[0047] Please refer to Figure 3 , in some embodiments, the walking aid 100 further includes a pulley structure 70. The pulley structure 70 includes a pulley connecting block 71 and a pulley 72 rotatably arranged on the pulley connecting block 71. The pulley connecting block 71 is slidably arranged on the support leg 10 along the axial direction of the support leg 10. Specifically, a part of the pulley connecting block 71 extends into the inside of the support leg 10, and the pulley connecting block 71 can slide up and down along the cavity inside the support leg 10. The pulley structure 70 is slidably arranged on the walking aid 100. The user can adjust the movement of the pulley 72 according to their own needs, lower the pulley 72 to the ground. At this time, the user can push the walking aid 100, or lift the pulley 72 to make the support legs 10 support on the ground. At this time, the walking aid 100 can be more stably supported on the ground.

[0048] Please refer to Figure 5, in some embodiments, the walking aid 100 further includes a pulley locking device 80. The pulley locking device 80 includes a connected locking portion 81 and an adjustment handle 82. The locking portion 81 is slidably disposed in the support leg 10 along the radial direction of the support leg 10. When the locking portion 81 slides to a preset position, the locking portion 81 abuts against the pulley connection block 71 to lock the pulley connection block 71. With this arrangement, the user can, according to their own needs, pull out the adjustment handle 82 and drive the locking portion 81 to move, causing the pulley connection block 71 above the locking portion 81 to move, and at the same time driving the pulley 72 to move. Then, the adjustment handle 82 is reset, the locking portion 81 is placed in place, and the pulley connection block 71 is fixed under the locking portion 81, which facilitates the user to choose whether to use the pulley 72 according to the actual usage situation and improves the practicability of the walking aid 100.
