[0039] Referring to Figures 6 to 8The limiting member 534 is made of hard metal and has a plate-shaped structure. The first channel 5341 and the second channel 5342 are formed in the limiting member 534 and are in communication with each other. The two limiting members 534 are respectively slidably installed at the front end 11 and the tail end 12 of the vehicle body 1 by means of the two elastic members. The following is an exemplary description of the installation of the first wheel 2 at the front end 11 of the vehicle body 1. First, the pressing plate 54 is pushed to move the limiting member 534 towards the elastic member, and the elastic member is in a compressed state. Then, the first rotating shaft 51 on the first wheel 2 is inserted through the first channel 5341 of the limiting member 534, so that the top end of the first rotating shaft 51 can be inserted into the first slot 13 at the front end 11 of the vehicle body 1. Then, the pressing on the pressing plate 54 is released. Under the action of the elastic member, the limiting member 534 is pushed by the elastic member, so that the second channel 5342 of the limiting member 534 abuts against the first ring groove 531 of the first rotating shaft 51. Since the inner diameter of the second channel 5342 is smaller than the outer diameter of the first ring groove 531, after the limiting member 534 is pushed by the elastic member and abuts against the first ring groove 531 of the first rotating shaft 51, the top wall and the bottom surface of the first ring groove 531 can further limit the position of the first rotating shaft 51, thereby improving the clamping and fixing effect of the first wheel 2. When the first wheel 2 needs to be removed from the front end 11 of the vehicle body 1, the pressing plate 54 is pushed towards the elastic member to make the first channel 5341 of the limiting member 534 coaxial with the first rotating shaft 51. At this time, the limiting member 534 no longer limits the first rotating shaft 51, and the first wheel 2 can be pulled down to be disassembled from the front end 11 of the vehicle body 1. The elastic member is used to push the limiting member 534 to abut against the first ring groove 531 of the first rotating shaft 51 or the second ring groove 532 of the second rotating shaft 52, so that the first wheel 2 and the second wheel 3 can be efficiently disassembled on the vehicle body 1, and the clamping structure has the characteristics of high disassembly efficiency, convenient operation and stable clamping structure.
[0040] In one or more embodiments, the top end of the first rotating shaft 51 and the second rotating shaft 52 has a prismatic structure, and the cross section of the first slot 13 and the second slot 14 has a prismatic structure matched with the first rotating shaft 51 or the second rotating shaft 52. Figure 9 Through the above arrangement, the first rotating shaft 51 or the second rotating shaft 52 can be rotated synchronously with the handle at the front end 11 of the vehicle body 1, or the first rotating shaft 51 or the second rotating shaft 52 can be fixed at the tail end 12 of the vehicle body 1.
[0041] In one or more embodiments, the elastic member is a spring or elastic steel.
[0042] In one or more embodiments, the first rotating shaft 51 is installed on the first wheel 2 by means of the first bearing 6, and the second rotating shaft 52 is installed on the second wheel 3 by means of the second bearing 7.
[0043] Referring toFigure 2 The first rotating shaft 51 is fixed to the inner ring of the first bearing 6, the outer ring of the first bearing 6 is rotatably installed on the first support 22 of the first wheel 2, the second rotating shaft 52 is fixedly installed on the inner ring of the second bearing 7, and the outer ring of the second bearing 7 is rotatably installed on the second support 32 of the second wheel 3; when the first wheel 2 is installed on the front end 11 or the tail end 12 of the vehicle body 1, the top surface of the first bearing 6 abuts against the front end 11 or the tail end 12 of the vehicle body 1, so that the handle of the front end 11 of the vehicle body 1 can more smoothly drive the first rotating shaft 51 to rotate, thereby controlling the first wheel 2 to rotate, so as to improve the use effect of the walker.
[0044] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
