[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0024] For ease of description, Figure 2 The Y-axis is specified in , but is not part of this embodiment.
[0025] like Figure 1-Figure 5 As shown, the utility model discloses an adjustable whiteboard, comprising a whiteboard body 1, a folding bracket 2 and a universal wheel assembly 3. The folding bracket 2 is used to support the whiteboard body 1, and the folding bracket 2 comprises a first folding member 21, a folding rod 22 and a second folding member 23.
[0026] The folding bracket 2 can be bent once at the first folding member 21, such as Figure 3 As shown, the first folding member 21 includes a connecting plate 211 and an extension plate 212 vertically connected to the connecting plate 211, and the top of the connecting plate 211 is detachably connected to the bottom of the whiteboard body 1. A first limiting opening 221 is provided at the top of the folding rod 22, and a second limiting opening 222 is provided at the side of the top of the folding rod 22 close to the Y axis. The extension plate 212 is inserted into the first limiting opening 221 or the second limiting opening 222, and the extension plate 212 is hinged to the folding rod 22.
[0027] A limiting rod 24 is provided at the second limiting opening 222, and the limiting rod 24 is used to clamp the extension plate 212 in the first limiting opening 221 or the second limiting opening 222. The side wall of the limiting rod 24 abuts against the extension plate 212, and the side wall of the rod body of the limiting rod 24 is preferably a plane, so as to better fit with the extension plate 212. One end of the limiting rod 24 abuts against the outer side wall of the folding rod 22, and the other end of the limiting rod 24 is provided with an external thread, and a nut is provided at the external thread, and the nut abuts against the other outer side wall of the folding rod 22, so as to realize the detachable connection between the limiting rod 24 and the folding rod 22.
[0028] like Figure 4As shown, a third limiting opening 223 is provided at the bottom of the folding rod 22, and a fourth limiting opening 224 is provided at the side of the bottom of the folding rod 22 away from the Y axis. The structure of the second folding member 23 is the same as that of the first folding member 21, and the extension plate 212 of the second folding member 23 is inserted into the third limiting opening 223 or the fourth limiting opening 224, and the second folding member 23 is hinged to the folding rod 22. A limiting rod 24 is also provided at the fourth limiting opening 224, and the limiting rod 24 has the same structure and function as the limiting rod 24 at the second limiting opening 222, which will not be described again. The connecting plate 211 of the second folding member 23 is detachably or fixedly connected to the universal wheel assembly 3.
[0029] like Figure 2 and Figure 5 As shown, the universal wheel assembly 3 includes a "T"-shaped frame 31 and a universal wheel 32. The top of the vertical rod of the "T"-shaped frame 31 is detachably or fixedly connected to the connecting plate 211 of the second folding member 23, and the bottom of the horizontal plate of the "T"-shaped frame 31 is connected to two universal wheels 32.
[0030] by Figure 1 and Figure 5 For example, when the folding bracket 2 needs to be adjusted, the first folding member 21 can be folded first. The specific operation is to first rotate the nut to remove the limit rod 24, then rotate the first folding member 21 from the first limit opening 221 to the second limit opening 222, and then install the limit rod 24 again. Then fold the second folding member 23, similarly remove the limit rod 24 first, then rotate the second folding member 23 from the third limit opening 223 to the fourth limit opening 224, and then install the limit rod 24 again. According to the above method, the whiteboard can be moved from Figure 1 Adjust the style to Figure 5 The above adjustment steps are in no particular order. When you need to restore the whiteboard, just follow the above method to restore the whiteboard. I will not repeat them here.
