[0034] Working principle: The tire blank production trolley is designed with a support base plate 100, casters 200, a second-layer support frame 400, and a second-layer support plate 500. During assembly, firstly, the handle 303 is pulled. Since the support base plate 100 is fixedly connected to the first side support block 300 through a folding assembly, the first side support block 300 will drive the side connecting block 600 to rotate around the axis 705. When the first side support block 300 moves to the vertical position, the side connecting block 600 is engaged with the sliding rod 803 through the limiting groove 604, thus completing the fixed support of the first side support block 300. Next, according to the actual size of the tire blank, the second-layer support frame 400 is inserted into the limiting mounting hole 302 of the appropriate height through the insertion post 403. Similarly, the second-layer support frame 400 on the other side is fixed, and the second-layer support plate 500 is connected through the second side support. Block 502 is slidably connected to the second-layer support frame 400. Bolts are then used to pass through the matching positioning holes 503 and 407 to fix the position of the second-layer support plate 500, facilitating the placement of the tire blank on the second layer. Finally, the universal wheel 200 is installed via a threaded connection. When it is necessary to disassemble the trolley for tire blank production, the bolts are turned to separate the second-layer support plate 500 and the second-layer support frame 400. Then, the second-layer support frame 400 is rotated 90 degrees to pull it out of the limiting mounting hole 302. The arc-shaped pressure plate 802 is pressed to disengage the slide rod 803 from the limiting groove 604, releasing the lock of the opposite side connecting block 600, allowing the side connecting block 600 to rotate freely. Pulling the handle 303 causes the side connecting block 600 to rotate, folding the first side support block 300, thus completing the disassembly of the trolley for tire blank production and greatly reducing the transportation space.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
