[0043] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The drawings in the embodiments of the present application will be described in conjunction with the Figure 1 to the drawings Figure 4 The technical scheme of the present application is described clearly and completely.

[0044] As Figures 1-2As shown, a material transfer trolley can be connected, including a trolley body, the trolley body is provided with a frame 1 for storing the goods need to be transported. Above the trolley can be bolted to the column to prevent the goods from falling during transportation, between the column can increase a plurality of longitudinal beams or cross beams for transporting decorative plates, bumpers and other easily bumped parts, which can effectively prevent the appearance of scratch defects. The lower part of the frame is provided with a roller, the front is provided with a front universal wheel 2 which can be easily turned, the rear is provided with a directional wheel 3.

[0045] The trolley is also provided with a front connecting mechanism assembly 4 for connecting with the rear connecting mechanism assembly 5. The front connecting mechanism assembly 4 includes an extension connecting piece 6 which can be connected with the rear connecting mechanism assembly 5, the extension connecting piece 6 is made of a rod and provided with a plurality of reinforcing ribs, which can effectively prevent deformation caused by large impact force during transportation. The front connecting mechanism assembly 4 is also provided with a connecting plate 7 which is designed in U shape, the middle is hollow, the front of the connecting plate 7 is welded with the extension connecting piece 6, the bolt 8 passes through the middle of the hollow from the back and the both ends of the bolt 8 are fixed on the supporting plate 17 which is fixedly connected with the trolley body by the nut 9, so that the connecting plate 7 can be rotated around the bolt 8 and can slide relative to the bolt 8.

[0046] The supporting plate 17 can be regarded as a fixed accessory of the trolley, which has vertical plates on both sides and a supporting plate at the bottom, the vertical plates serve as the mounting part of the nut 9 and the bolt 8, and a first fixing groove 11 is formed in the top edge and a second fixing groove 12 is formed in the side edge; the supporting plate at the bottom can support the combination of the connecting plate 7 and the extension connecting piece 6 in a flat state; the supporting plate at the bottom is provided with a through groove to avoid interference when the connecting plate is erected.

[0047] When the extension connecting piece 6 and the connecting plate 7 are rotated and lifted as a whole when the vehicle is not in use, the space occupied can be reduced; the flange 10 of the connecting plate 7 is clamped in the first fixing groove 11 to play a stabilizing role. When the front connecting mechanism assembly 4 and the rear connecting mechanism assembly 5 are connected and used, the head of the extension connecting piece 6 is slightly lower than the tail of the connecting plate 7 to prevent the extension connecting piece 6 and the connecting plate 7 from being raised when the vehicle is decelerating or stopping, and then the front and rear vehicles collide. In order to further eliminate this hidden danger, the front connecting mechanism assembly 4 is also provided with a second fixing groove 12, and the connecting plate 7 is provided with a flange 10, when the vehicle is decelerating or stopping, the connecting plate 7 moves backward and the flange 10 slides into the first fixing groove 11, preventing the extension connecting piece 6 and the connecting plate 7 from being raised.

[0048] The trolley is also provided with a rear connecting mechanism assembly 5, which is provided with a rotating shaft fixing pipe 13 to facilitate the rotation of the rotating shaft 15, and the rotating shaft 15 is welded with a hanging rod 14 in the middle, and the two sections of the hanging rod 14 are welded with different lengths, so that the hanging rod 14 is in a natural drooping state, and in the acceleration process of the vehicle, the hanging rod 14 can be hung on the lower vertical rod part of the extension connecting piece 6 to be pulled out, and the rear connecting mechanism assembly 5 is also provided with a long circular groove 16 to facilitate the rotation of the hanging rod 14 (but cannot be rotated to be pulled out of the long circular groove 16, and the hanging rod 14 can also be limited in position during acceleration or driving, and when the vehicle is used, the pressure rod part on the upper part of the hanging rod can be pressed or stepped to quickly separate the two connected trolleys.

[0049] Trolley connecting operation: the trolleys move towards each other, the extension connecting piece 6 is inserted into the rear connecting mechanism assembly 5, the hanging rod 14 is first lifted by the extension connecting piece 6, and then falls to be clamped on the extension connecting piece 6.

[0050] Trolley separation operation: first, the trolleys move towards each other, the lifting space of the lower part of the hanging rod 14 is opened, then the upper half of the hanging rod 14 is stepped or pressed, the lower half of the hanging rod 14 is lifted, and the extension connecting piece 6 is separated from the contact, and then the trolleys are separated.

[0051] It can be seen that the trolley provided by the embodiment can be connected in head-to-tail mode, which greatly improves the single transfer amount and transfer efficiency of the material, and the operation of connecting and separating the trolley is very simple, low in cost and high in efficiency.

[0052] The above only describes preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
