[0007] Furthermore, the limiting component includes two collars, and each collar is provided with a transverse connecting rod, and the vertical limiting rod is fixed on the two transverse connecting rods.

[0008] Furthermore, a limiting ring is arranged on the chassis, and when the vertical limiting rod is hung on the rectangular upper frame, the lower end of the vertical limiting rod is inserted into the limiting ring.

[0009] Furthermore, an additional support rod is arranged at the middle position in the long side direction of the frame, and the limiting component is arranged on the additional support rod and the vertical support rod in the adjacent side direction.

[0010] Furthermore, clamping rails with multiple heights are arranged between the additional support rods in the width direction and between the vertical support rods for placing material trays.

[0011] Further, the vertical support rod extends downward to below the chassis, and the universal wheels are arranged at the lower end of the vertical support rod.

[0012] The beneficial effects of the present utility model are as follows:

[0013] (1) When taking and placing the material tray, the limiting rod is opened, and the limiting rod is locked during movement to ensure that the material will not fall during movement;

[0014] (2) The structure is simple and the operation is convenient;

[0015] (3) It is integrally designed with the trolley and does not occupy space. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will describe in detail the specific embodiments of a limiting trolley of the present utility model with reference to the drawings.

[0027] Referring to Att Figure 1 、 2 , the limiting trolley includes a chassis 1 and a frame 2. The frame 2 is installed on the chassis 1. The frame 2 includes a rectangular upper frame 3. At the four corners of the rectangular upper frame 3, four vertical support rods 4 are provided. The vertical support rods 4 extend downward to below the chassis 1, and the universal wheels 5 are arranged at the lower ends of the vertical support rods 4.

[0028] An additional support rod 6 is provided at the middle position in the long side direction of the frame 2, and the additional support rod 6 divides the long side of the frame 2 into two parts. Between the additional support rods 6 in the width direction and between the vertical support rods 4, a plurality of card rails 7 of different heights are provided for placing the material trays.

[0029] A limit assembly 8 is provided on the additional support rod 6 and the vertical support rod 4 on the adjacent side direction. The limit assembly 8 includes two collar rings 9 sleeved on the vertical support rod 4. A transverse connecting rod 10 is provided on the collar ring 9. The other end of the transverse connecting rod 10 is fixedly provided with a vertical limiting rod 11. A hook 12 is provided at the top of the vertical limiting rod 11. A limit ring 13 is provided on the chassis 1 for hanging on the rectangular upper frame 3 when the vertical limiting rod 11 rotates to the rectangular upper frame 3, and the lower end of the vertical limiting rod 11 is inserted into the limit ring 13.

[0030] The two collar rings 9 are respectively close to the top or bottom of the additional support rod 6 or the vertical support rod 4. When the vertical limiting rod 11 is lifted upward, the lifting height of the top collar ring 9 is restricted, so that the hook 12 of the vertical limiting rod 11 can be disengaged from the frame 2 and the lower end of the vertical limiting rod 11 can be disengaged from the limit ring 13. When the vertical limiting rod 11 is unlocked, the bottom collar ring 9 restricts the vertical limiting rod 11 from falling too far downward.

[0031] When the limit trolley is picking up and placing materials, first unlock the locked vertical limiting rod 11, lift the vertical limiting rod 11 upward, the hook 12 of the vertical limiting rod 11 is disengaged from the frame 2, the lower end of the vertical limiting rod 11 is disengaged from the limit ring 13, and rotate the vertical limiting rod 11 outward to unlock. After the material picking and placing are completed, lift the vertical limiting rod 11 upward, rotate it inward until the vertical limiting rod 11 is close to the frame 2 and then lower it, so that the hook 12 of the vertical limiting rod 11 is hooked on the frame 2, and the lower end of the vertical limiting rod 11 is inserted into the limit ring 13 to complete the locking.

[0032] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
