The front leg portion 121 is detachably connected to the front support leg 131, and the rear leg portion 122 is detachably connected to the rear support leg 132. Therefore, by adjusting the relative connection position of the legs and the support legs, the height of the side frames of the walking aid can be adjusted.

[0041] The embodiment of the present application selects to arrange the hollow cross brace 40 between the front side leg 131 and the rear side leg 132, and the front side leg 131 and the rear side leg 132 are fixedly connected together through the cross brace 40, which plays a role of strengthening the structural strength of the side frame assembly. Moreover, the front side leg 131 of the left side frame assembly 10 and the front side leg 131 of the right side frame assembly 11 are connected through the front bar 41, so as to fixedly connect the left side frame assembly 10 and the right side frame assembly 11 with each other. By arranging the front bar 41 on the legs of the left side frame assembly 10 and the right side frame assembly 11, the height adjustment of the respective side frames of the left side frame assembly 10 and the right side frame assembly 11 can be avoided, and the structural strength between the left side frame assembly 10 and the right side frame assembly 11 can be ensured. The front bar 41 used in the embodiment of the present application can be a plate, a square rod or a cylindrical rod.

[0042] The left side frame assembly 10 and the right side frame assembly 11 are respectively provided with the lifting adjustment mechanism 20, so as to adjust the respective side frame heights of the left side frame assembly 10 and the right side frame assembly 11 through the lifting adjustment mechanism 20, and the lifting adjustment mechanism 20 is arranged on the cross brace 40. Specifically, the lifting adjustment mechanism 20 has the positioning button 204, the positioning piece 201, the first sliding block 206, the second sliding block 207, the connecting rod 202 and the elastic reset piece 203. Since the cross brace 40 is an inner hollow structure, the button assembly hole is arranged on the cross brace 40, the positioning button 204 is installed on the cross brace 40 through the button cover 2043, and the positioning button 204 has two downward extending connecting shaft arms 2041, and the two connecting shaft arms 2041 are provided with the guide shaft 2042.

[0043] The two guide sliding seats 205 are installed in the cross brace 40 corresponding to the position of the positioning button 204, and the guide sliding seat 205 has the first guide groove 2051 and the second guide groove 2052. The first guide groove 2051 extends in the direction of the side frame height adjustment locking, and the second guide groove 2052 extends in the pressing direction of the positioning button 204. Therefore, the first sliding block 206 and the second sliding block 207 are correspondingly and slidably installed in the first guide groove 2051 of the two guide sliding seats 205, and the first sliding block 206 and the second sliding block 207 are in a staggered sliding assembly relationship, the connecting shaft arm 2041 of the positioning button 204 is movably installed in the second guide groove 2052, so as to realize the assembly of the positioning button 204, the first sliding block 206 and the second sliding block 207 on the cross brace 40 through the guide sliding seat 205.

[0044] The first slider 206 and the second slider 207 are respectively provided with guide grooves 208, the guide grooves 208 of the first slider 206 and the second slider 207 are respectively arranged obliquely downward towards the respective elastic reverse reset directions, so that the guide grooves 208 of the first slider 206 and the second slider 207 are arranged in a substantially "eight" shape. The two connecting shaft arms 2041 of the positioning button 204 extend towards the guide grooves 208, so that the guide shafts 2042 on the two connecting shaft arms 2041 are respectively correspondingly in sliding fit with the guide grooves 208 on the first slider 206 and the second slider 207.

[0045] Moreover, the reverse sliding ends of the first slider 206 and the second slider 207 are connected to the positioning member 201 through the connecting rod 202, so that the first slider 206 and the second slider 207 can drive the positioning member 201 through the connecting rod 202. In addition, the opposite sliding ends of the first slider 206 and the second slider 207 are connected to the elastic reset member 203 for applying reverse sliding elastic force, so that after the positioning button 204 is released, the first slider 206 and the second slider 207 can be reversely reset and slid under the elastic action of the elastic reset member 203.

[0046] The front side pin portion 121 and the rear side pin portion 122 are respectively provided with a plurality of positioning holes 14 in the length direction, and the front side leg 131 and the rear side leg 132 are respectively provided with holes for the positioning member 201 to pass through at the connection positions with the cross support 40. In the embodiment, the front side leg 131 is sleeved on the front side pin portion 121, and the positioning member 201 on the front side leg 131 and the cross support 40 is correspondingly inserted into the positioning hole 14 on the front side pin portion 121, so as to lock the assembly position between the front side leg 131 and the front side pin portion 121.

[0047] The rear side leg 132 is sleeved on the rear side pin portion 122, and the rear side leg 132 and the positioning member 201 on the cross support 40 are correspondingly inserted into the positioning hole 14 on the rear side pin portion 122, so as to lock the assembly position between the rear side leg 132 and the rear side pin portion 122. In this way, the side frame heights of the left side frame assembly 10 and the right side frame assembly 11 of the walker are adjusted, which is especially suitable for the targeted use of people with long or short arms, has a humanized design, and does not affect the side frame height of the other side when the side frame height of the left side frame assembly 10 or the right side frame assembly 11 is adjusted, and the overall balance of the walker is maintained, so as to ensure the normal and safe use of the user. Moreover, the lifting and adjusting mechanism 20 is arranged on the cross support 40 of the leg, so that the user can adjust the side frame height with the hand when using the walker, and the use convenience of the walker of the embodiment is higher and more flexible compared with the previous implementation means of bending down to press the positioning member 201 to adjust the side frame height.

[0048] According to the above description, the cross brace 40 is fixedly connected between the front side leg 131 and the rear side leg 132, and when the positioning member 201 is installed, a limiting seat 401 is arranged on each of the two ends of the cross brace 40 connected with the front side leg 131 and the rear side leg 132, a through hole is formed in the limiting seat 401 and communicates with the through hole on the leg and the pipe foot, and the positioning member 201 is slidably arranged in the through hole. Under the control of the positioning button 204, the positioning member 201 can reciprocate in the through hole of the limiting seat 401, and the through hole can guide the positioning member 201 to be accurately inserted into or withdrawn from the positioning hole 14, thereby improving the smoothness of the height adjustment of the side frame of the walking aid.

[0049] Specifically, when the positioning button 204 is pressed, the guide shaft 2042 slides obliquely downward along the guide groove 208, the first slider 206 and the second slider 207 slide in opposite directions, and the first slider 206 and the second slider 207 respectively drive the positioning member 201 to exit the positioning hole 14 through the connecting rod 202, so as to unlock the connection state of the leg and the pipe foot. At this time, the leg can be pulled to adjust the height of the side frame.

[0050] When the positioning button 204 is released, the first slider 206 and the second slider 207 elastically reverse and slide, the guide shaft 2042 slides obliquely upward along the guide groove 208, and the first slider 206 and the second slider 207 respectively push the positioning member 201 to insert into the positioning hole 14 through the connecting rod 202, so as to lock the connection state of the leg and the pipe foot. At this time, the leg cannot be adjusted.

[0051] In this way, the left side frame assembly 10 and the right side frame assembly 11 are respectively provided with the lifting adjustment mechanism 20, the positioning button 204 is arranged on the lifting adjustment mechanism 20, the positioning member 201 is controlled to insert into or exit the positioning hole 14 arranged on the support frame and the leg, and the connection state between the support frame and the leg is locked or released. Since the left side frame assembly 10 and the right side frame assembly 11 are fixedly connected with each other through the leg, the height of the side frame of the left side frame assembly 10 and the right side frame assembly 11 can be independently adjusted through the positioning button 204, and the overall balance of the walking aid can be maintained. Compared with the prior art in which the left and right side frames of the walking aid are fixedly connected and the height of the left and right side frames needs to be adjusted simultaneously, the use convenience and flexibility are higher, and the walking aid can be used by special groups such as people with long or short arms, and the design is more humanized.

[0052] The mute assembly 30 has an elastic strip 301 and quick release heads arranged at both ends 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.

[0053] When installing the elastic strip 301, the first end of the elastic strip 301 is threaded along the tube hole of the front side foot part 121, the hand holding part 123 and the rear side foot part 122 until the first end of the elastic strip 301 is connected to one end of the rear side leg 132 connected by the cross brace 40. Since the quick release holes are provided on both ends of the cross brace 40, the quick release heads at both ends of the elastic strip 301 can be quickly and detachably connected to the quick release holes at both ends of the cross brace 40. In addition, the quick release head of the second end of the elastic strip 301 is connected to one end of the front side leg 131 connected by the cross brace 40.

[0054] Since the cross brace 40 is fixedly connected to the front side leg 131 and the rear side leg 132, when the cross brace 40 is pulled tight by the elastic strip 301, that is, when the front side leg 131 and the rear side leg 132 are pulled tight, the front side foot part 121 and the front side leg 131, and the rear side foot part 122 and the rear side leg 132 always maintain a state of being elastically pulled towards each other.

[0055] In this way, by providing the elastic strip 301, the foot part and the leg are elastically connected by the elastic strip 301. Even if the assembly gap between the positioning hole 14 and the positioning member 201 increases due to wear over time, since the positioning member 201 is provided on the leg by the cross brace 40 and the positioning hole 14 is provided on the foot part, when the leg and the foot part are elastically pulled towards each other by the elastic strip 301, the positioning member 201 and the positioning hole 14 always maintain a state of being in close proximity, regardless of whether the user is lifting or lowering the walker. Thus, the problem of metal collision noise caused by the positioning rod colliding with the positioning hole 14 during use is avoided, the silent use effect of the walker is improved, and the user's experience is improved.

[0056] Second embodiment

[0057] The difference between the embodiments of the present application and the first embodiment is in the position of the cross brace 40, the assembly method between the foot part and the leg, and the setting of the elastic strip 301. The same parts are not repeated here.

[0058] Specifically, as shown in Figures 5-6 The cross brace 40 is arranged between the front side foot part 121 and the rear side foot part 122. The front side foot part 121 is detachably sleeved on the front side leg 131, and the positioning member 201 on the front side foot part 121 and the cross brace 40 is inserted into the positioning hole 14 on the front side leg 131, thereby locking the assembly position between the front side leg 131 and the front side foot part 121.

[0059] The rear leg 132 is detachably sleeved with the rear pipe foot part 122, and the positioning member 201 on the cross brace 40 is correspondingly inserted into the positioning hole 14 on the rear leg 132, thereby locking the assembly position between the rear leg 132 and the rear pipe foot part 122. In order to increase the structural strength of the leg, the cross brace 40 can be added between the front leg 131 and the rear leg 132. Similarly, the height of the left side frame assembly 10 and the right side frame assembly 11 of the walker can be adjusted, which is especially suitable for people with long or short arms and is humanized design. Moreover, the lifting adjusting mechanism 20 is arranged on the cross brace 40 of the pipe foot part, so that the user can adjust the height of the side frame when using the walker, and the convenience and flexibility of the walker are higher than that of the prior art.

[0060] In the aspect of the mute design of the walker, the two ends of the elastic strip 301 of the mute assembly 30 are respectively provided with limiting blocks 302. The elastic strip 301 used in the embodiment of the application can be an elastic elastic band or a telescopic spring.

[0061] When the elastic strip 301 is installed, the first end of the elastic strip 301 is arranged in the pipe hole of the front pipe foot part 121, the hand holding part 123 and the rear pipe foot part 122, and the first end of the elastic strip 301 is detachably buckled on the end hole of the foot seat of the rear leg 132 through the limiting block 302. In addition, the second end of the elastic strip 301 is detachably buckled on the end hole of the foot seat of the front leg 131 through the limiting block 302. The mute assembly 30 of the embodiment of the application can also achieve the mute effect of the walker in the first embodiment.

[0062] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the scope of protection of the utility model. Any non-essential changes and replacements made by those skilled in the art on the basis of the utility model belong to the scope of protection of the utility model.
