[0032] As Figures 1-7As shown, a portable silent walking aid includes a side frame, a support leg 20 and a silent assembly 30, wherein the side frame has a left side frame 10 and a right side frame 11 for holding by the left and right hands of a user, the overall structure of the left side frame 10 and the right side frame 11 is approximately U-shaped, and in the use state of the walking aid, the upper parts of the left side frame 10 and the right side frame 11 are provided as hand holding parts 101 for holding by the user, and the lower parts of the left side frame 10 and the right side frame 11 are respectively provided with two tube foot parts 102.

[0033] The left side frame 10 and the right side frame 11 are connected through a front bar 41, so as to further improve the structural strength of the left side frame 10 and the right side frame 11, and the front bar 41 used can be a plate, a square rod or a cylindrical rod. In order to facilitate the assembly convenience between the front bar 41 and the left side frame 10 and the right side frame 11, sleeve pipes 411 are arranged at the left and right ends of the front bar 41, and the front bar 41 is sleeved on the tube foot parts 102 at the front sides of the left side frame 10 and the right side frame 11 through the sleeve pipes 411 at the left and right ends thereof.

[0034] In addition, the front and rear tube foot parts 102 of the left side frame 10 and the right side frame 11 are connected through a cross brace 40, so as to further improve the structural strength of the left side frame 10 and the right side frame 11 by arranging the cross brace 40, so that the walking aid can be used by users with different body shapes and weights, thereby improving the durability of the walking aid.

[0035] When installing the tube foot part 102 and the support leg 20, the embodiment of the present application selects to set the pipe diameter of the support leg 20 to be greater than the pipe diameter of the tube foot part 102, so as to facilitate the sleeving of the support leg 20 into the lower end of the tube foot part 102. Moreover, a sleeve ring 201 is arranged at the upper end of the support leg 20, and when the support leg 20 is sleeved on the tube foot part 102, the sleeve ring 201 can be adaptively sleeved on the outside of the tube foot part 102, so as to improve the assembly adaptability and stability between the upper end of the support leg 20 and the tube foot part 102. In addition, a rubber foot pad 21 is arranged at the lower end of the support leg 20 which contacts the ground, for buffering the impact force between the support leg 20 and the ground, so as to play a certain role of shock absorption and noise reduction.

[0036] The embodiment of the present application selects to arrange a plurality of through internal positioning holes 22 in the length direction of the support leg 20, and to arrange a positioning piece 23 on the tube foot part 102, the positioning piece 23 being elastically arranged on the tube foot part 102, and under the pressing of external force, the positioning piece 23 can be stretched into the tube hole of the tube foot part 102.

[0037] Therefore, when the support leg 20 is sleeved on the outside of the tube foot part 102, the length of the tube foot part 102 deep into the support leg 20 can be adjusted according to the use demand of the user, so as to adjust the use height of the walking aid, and after determining the use height, the positioning piece 23 is aligned with the specified positioning hole 22 on the support leg 20, so that the positioning piece 23 is inserted into the specified positioning hole 22, so as to lock the assembly relationship between the support leg 20 and the tube foot part 102.

[0038] When the height of the walker needs to be adjusted, the user only needs to press the positioning member 23 to make the positioning member 23 disengage from the positioning hole 22 and retreat into the inner cavity of the supporting leg 20, then adjust the length of the tube foot part 102 extending into the tube hole of the supporting leg 20, the tube foot part 102 moves along the inner cavity of the supporting leg 20 and makes the positioning member 23 align with the specified positioning hole 22, and then the operation of inserting the positioning member 23 into the positioning hole 22 is repeated.

[0039] Preferably, the mute assembly 30 has an elastic strip 301, a quick release head 302 arranged at the first end of the elastic strip 301, and a limiting block 303 arranged at the second end of the elastic strip 301. The elastic strip 301 used in the embodiment of the application can be an elastic elastic band or a telescopic spring.

[0040] In use, the pin 12 is arranged in the tube hole of the tube foot part 102, the end hole 202 compatible with the elastic strip 301 is arranged at the lower end of the supporting leg 20, then the first end of the elastic strip 301 is inserted into the pin 12 inside the tube foot part 102 from the end hole 202 at the lower end of the supporting leg 20, and the second end of the elastic strip 301 is limited by the limiting block 303 and the end hole 202 to prevent the second end of the elastic strip 301 from disengaging from the lower end of the supporting leg 20. Therefore, after the elastic strip 301 is assembled between the supporting leg 20 and the tube foot part 102, the supporting leg 20 and the tube foot part 102 of the left side frame 10 and the right side frame 11 always maintain an elastic tension state.

[0041] Therefore, by arranging the elastic strip 301, the tube foot part 102 and the supporting leg 20 are elastically connected through the elastic strip 301. Even if the assembly gap between the positioning hole 22 and the positioning member 23 increases due to wear over time, since the positioning member 23 is arranged on the tube foot part 102 and the positioning hole 22 is arranged on the supporting leg 20, when the tube foot part 102 and the supporting leg 20 are elastically tensioned through the elastic strip 301, the positioning member 23 and the positioning hole 22 are always in close contact no matter whether the user is lifting the walker or putting the walker on the ground. Therefore, the problem of metal collision noise caused by the collision between the positioning rod and the positioning hole 22 in use is avoided, the mute use effect of the walker is improved, and the user experience is improved.
