DETAILED DESCRIPTION

[0018] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] The utility model provides a walking aid, such as Figure 1-4 As shown, the walker includes a bracket 100 and a seat 200, the seat 200 is connected to the bracket 100 through a support rod 300, the seat 200 includes a base 210 and a folding frame 220, the base 210 is fixed on the support rod 300, the folding frame 220 is rotatably connected to the base 210, a seat cushion 221 is provided on the first end surface of the folding frame 220, a knee pad 222 is provided on the second end surface of the folding frame 220, the folding frame 220 includes a first state and a second state, so that when the folding frame 220 is in the first state, the folding frame 220 is superimposed on the base 210, and the seat cushion 221 faces upward, so that the user can sit and rest. The folding frame 220 is connected to the base 210 via a hinge 600. To put the folding frame 220 in the second state, the folding frame 220 needs to be rotated along the hinge 600 so that the folding frame 220 and the base 210 are arranged horizontally. At this time, the knee pad 222 faces upward, and the user can place the injured leg on the knee pad 222, use the knee and hands of the injured leg to support the body, and use the other intact foot to push off the ground and slide forward. Since the knee pad 222 provides the main support for the human body, the strength required for the hands is greatly reduced, making the walker easier to use, and the walker can move forward continuously and uninterruptedly, thereby improving the forward efficiency.

[0020] The base 210 has a rotating shaft 211, and the rotating shaft 211 is located at the center of the base 210. The support rod 300 has a rotating shaft hole 310, and the rotating shaft 211 is inserted into the rotating shaft hole 310. When the folding frame 220 is in the second state, the horizontal position of the folding frame 220 relative to the base 210 can be changed, so that the knee pad 222 can adapt to the injured left leg or right leg. The rotating shaft 211 arranged on the base 210 can make the base 210 rotatable under the action of the rotating shaft hole 310, thereby achieving the purpose of changing the horizontal position of the folding frame 220 relative to the base 210. Figure 2 The knee pad 222 is located on the left side of the base 210, so that the user can place the left knee on the knee pad 222. Figure 3 The knee pad 222 is located on the right side of the base 210 , making it convenient for the user to place the right knee on the knee pad 222 .

[0021] like Figure 4As shown, the base 210 has a first fixing hole 212 and a second fixing hole 213 symmetrically arranged about the rotating axis 211, and the support rod 300 has a mounting hole 320. When the folding frame 220 is in a first state, the first fixing hole 212 corresponds to the mounting hole 320. When the folding frame 220 is in a second state and the position of the folding frame 220 is changed at the same time, the second fixing hole 213 corresponds to the mounting hole 320. The folding frame 220 is positioned by a positioning member 400 passing through the first fixing hole 212 and the mounting hole 320 or the second fixing hole 213 and the mounting hole 320. The positioning member 400 may be a screw or a pin. When the position of the knee pad 222 in the second state needs to be changed, the pin is pulled out from the mounting hole 320 and the first fixing hole 212, the base 210 is rotated so that the knee pad 222 is at the corresponding position, and then the positioning member 400 is inserted and passed through the second fixing hole 213 and the mounting hole 320, so that the base 210 is fixed on the support rod 300. In other optional embodiments, the mounting holes 320 may be two corresponding to the first fixing hole 212 and the second fixing hole 213, that is, the first mounting hole and the second mounting hole, and two positioning members 400 are provided at the same time, namely the first positioning member and the second positioning member, the first positioning member passes through the first fixing hole 212 and the first mounting hole, and the second positioning member passes through the second fixing hole 213 and the second mounting hole.

[0022] The pad surface of the knee pad 222 is a concave surface 223, and the concave surface 223 has protrusions 224 on both sides, which can prevent the knee placed on the knee pad 222 from shifting left and right and sliding off. The base 210 has a receiving cavity 214 with an opening facing upward. When the folding frame 220 is in the first state, the knee pad 222 is embedded in the receiving cavity 214. The protrusions 224 on both sides of the concave surface 223 can not only position the knee, but also can be embedded in the receiving cavity 214 of the base 210. The folding frame 220 and the base 210 are directly in contact, making the seat cushion 221 in the first state more stable and preventing the knee pad 222 from being deformed due to long-term pressure.

[0023] A back panel 500 is provided on the bracket 100 above the front end of the support rod 300. The back panel 500 is provided with an elastic back pad, which can support the upper body of the user and reduce the force of both hands supporting the bracket 100. Even when the hands are not exerting force, the back pad can support the user more comfortably, allowing the user to quickly slide forward with one leg, or the user can sit on the cushion 221 with his back against the back panel 500 to rest.
