[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0018] Example 1: Reference Figure 1-3The utility model provides a foldable mobile chassis, including a device body 100, the device body 100 includes a chassis body 110, and universal wheels 111 are installed at the four corners of the bottom end of the chassis body 110. A bracket assembly 200 is provided on the outside of the chassis body 110, and the bracket assembly 200 includes a mounting frame 210, and the mounting frame 210 is fixedly installed on the outside of the chassis body 110. The inside of the mounting frame 210 is hinged with a support arm 211 through a rotating shaft, and the bottom end of the support arm 211 is installed with a support seat 212 through an adjusting assembly 300. The rotating shaft inside the mounting frame 210 is a damping rotating shaft. The adjusting assembly 300 includes a nut sleeve 310, and the nut sleeve 310 is fixedly installed at the top end of the support arm 211 away from the mounting frame 210. A screw rod 311 is installed inside the nut sleeve 310 through a thread, and the screw rod 311 movably passes through the nut sleeve 310 and the support arm 211, and the bottom end of the screw rod 311 is fixedly connected to the top of the support seat 212.
[0019] The working principle of the first embodiment of the utility model is as follows: when the cone moves, by holding the screw rod 311 and rotating it, the screw rod 311 drives the support seat 212 to move upward until the height of the support seat 212 is higher than the universal wheel 111, the bracket assembly 200 is held and rotated, so that the outer surface of the support arm 211 is respectively attached to the four sides of the chassis body 110 in sequence, and the device can be pulled and displaced. When the device moves to the desired site, the support arm 211 is rotated outward in sequence, so that the support arm 211 is rotated to Figure 1 Then, the screw rod 311 is held and rotated so that the support seat 212 is in contact with the ground, thereby completing the position limiting of the chassis body 110. Example 1
[0020] The difference between Example 2 and Example 1 is that there are four bracket assemblies 200, which are installed at the four corners of the chassis body 110. An armrest 112 is hinged on the outer side of the chassis body 110, and the cross-sectional shape of the armrest 112 is circular. The arrangement of the four bracket assemblies 200 ensures the stability of the device limit. The hinged armrest 112 facilitates adjusting the angle of the armrest 112 and holding the armrest 112 to pull and apply force to the device body 100.
