[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] like Figures 1-3As shown, a foldable mobile trolley includes a front leg assembly 1, a rear leg assembly 2, and a storage board 3. The top of the front leg assembly 1 is rotatably connected to the rear leg assembly 2 via a pivot pin 4. The storage board 3 is detachably connected to the front leg assembly 1 and the rear leg assembly 2 to form a stable triangular support structure. Universal wheels 5 are provided at the bottom of the front leg assembly 1 and the rear leg assembly 2. When the mobile trolley is folded, the rear leg assembly 2 can be placed inside the front leg assembly 1. When the mobile trolley is in use, the front leg assembly 1 and the rear leg assembly 2 are rotated and unfolded, and at least one layer of storage board 3 is detachably provided between the front leg assembly 1 and the rear leg assembly 2.

[0021] It is understood that the front leg assembly 1 and the rear leg assembly 2 of the mobile trolley in this application are rotatably connected, which satisfies the requirements of tool-free quick folding and small storage space.

[0022] In a specific embodiment, the shelf 3 includes two components. The front foot assembly 1 includes a U-shaped frame, the top open side of which is connected to the rear foot assembly 2 via a pin. The side walls of the shelf 3 are fixed to the side frame 11 of the U-shaped frame by hand-tightening screws. Casters 5 are mounted on the bottom frame 12 of the U-shaped frame. The rear foot assembly 2 includes a top rod 21, a bottom rod 22, and a connecting frame 23. The top rod 21 is rotatably connected to the open side of the U-shaped frame via a pin. Casters 5 are mounted on the bottom rod 22. The connecting frame 23 is vertically positioned between the top rod 21 and the bottom rod 22. The rear end wall of the shelf 3 is fixed to the connecting frame 23 by hand-tightening screws.

[0023] Continue reading Figures 1-3 It is understood that the connecting frame 23 includes two parallel and spaced vertical rods 231, which are connected by at least one horizontal bar 232. The rear end wall of the shelf 3 is fixed to the horizontal bar 232 by a hand-tightened screw. The side frame 11 and the horizontal bar 232 of the U-shaped frame are provided with first mounting holes, and the side wall and the rear end wall of the shelf 3 are provided with second mounting holes. The hand-tightened screw is inserted through the first mounting hole of the side frame 11 or the horizontal bar 232 of the U-shaped frame and detachably assembled with the second mounting hole of the side wall or the rear end wall of the shelf 3. In order to ensure the stability of the shelf 3, the connecting frame 23 is provided with a support rod 24 at the position corresponding to the horizontal bar 232, and the shelf 3 is supported on the support rod 24.

[0024] This application uses hand-tightened screws instead of conventional screws to fix the shelf 3, which requires no tools for installation. It is quick and convenient for users to install, effectively saving customers' assembly time.

[0025] The specific installation process of the mobile cart is as follows: the front leg assembly 1 and the rear leg assembly 2 are connected together in advance with the axle pin 4, and the front leg assembly 1 and the rear leg assembly 2 are unfolded; then the shelf 3 is fixed to the front leg assembly with a hand screw; finally, the shelf 3 is fixed to the rear leg assembly 2 with a hand screw.
