Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-5 A pallet trolley includes a frame 1, which can be square and can be welded from multiple square tubes. A steel plate 2 is laid on the frame 1, and the steel plate 2 can be fixed to the surface of the frame 1 by welding; a handrail 3 is provided on one side of the frame 1 to facilitate the transportation of the pallet trolley.

[0025] A stacking unit 4 is provided on the frame 1, and the stacking unit 4 includes at least four stacking bowls 41 and at least four insertion rods 42. The multiple stacking bowls 41 can be evenly distributed at the four corners of the bottom of the frame 1, and the multiple insertion rods 42 can be evenly distributed at the four corners of the top of the frame 1, and correspond coaxially to the multiple stacking bowls 41 one by one. The stacking bowl 41 may include a square fixed block, a slot is provided in the middle of the fixed block, an inverted conical block is provided at the bottom of the fixed block, a conical groove is provided in the middle of the conical block, and the conical groove is coaxially arranged with the slot, the insertion rod 42 can penetrate the conical groove and be plugged into the slot, and the stacking of multiple pallet trolleys can be achieved by plugging and matching the multiple insertion rods 42 with the stacking bowls 41.

[0026] The frame 1 is also provided with a connecting device 5, which includes a pluggable traction trailer 51 and a hook 52. A fixing seat 53 is provided on the outer wall of the frame 1 on the side close to the handrail 3, and a fixing rod 54 is provided on the fixing seat 53. The fixing rod 54 is sleeved with the traction trailer 51. The fixing rod 54 and the traction trailer 51 are clearance-matched, so that the traction trailer 51 can not only rotate on the fixing rod 54, but also move vertically on the fixing rod 54 when the traction trailer 51 is in a vertical state. A hanging hole is provided on the top of the traction trailer 51; a fixing plate 55 is provided on the outer wall of the frame 1 on the side close to the handrail 3, and a fixing plate 55 is provided on the fixing plate 55. A base plate 56 and a mounting plate 57 are provided. The mounting plate 57 is arranged parallel to the top of the base plate 56. A rotatable hook 52 is provided on the mounting plate 57. A connecting rod can be arranged on the side of the mounting plate 57 away from the fixed plate 55. The hook 52 can rotate on the connecting rod. At the same time, a through hole is provided in the middle of the mounting plate 57, so that the bottom of the hook 52 can pass through the through hole and be plugged and matched with the traction trailer 51 when it is rotated; the top of the traction trailer 51 is placed horizontally on the base plate 56, and the hook 52 is rotated to pass through the hanging hole to realize the plug-in fit between the hook 52 and the traction trailer 51, thereby realizing the connection between the two pallet trolleys.

[0027] In some embodiments, a limiting groove is provided on the fixing seat 53, and the bottom of the traction trailer 51 can be plugged into the limiting groove. When the traction trailer 51 is idle, the traction trailer 51 can be rotated to make the traction trailer 51 in a vertical state and move downward and plugged into the limiting groove, thereby achieving the fixation of the traction trailer 51 in a vertical state and reducing the space occupied by the pallet cart when it is idle.

[0028] In some embodiments, a torsion spring is provided between the hook 52 and the connecting rod, which can maintain the connection state between the hook 52 and the traction trailer 51, improve the connection strength when the hook 52 and the traction trailer 51 are plugged in, and avoid the separation of the hook 52 and the traction trailer 51 when multiple pallet trucks are operated in conjunction.

[0029] In some embodiments, two shovel feet 6 are symmetrically provided at the bottom of the frame 1. The shovel feet 6 are grooved tubes fixed at the bottom of the frame 1. The grooved tubes can be welded from three square tubes. They have a limiting function when a forklift stacks the pallet cart, ensuring the safety and stability of the stacking operation. A suitable height can be designed to serve as a support point for the pallet cart when stacking, thereby improving the stability after stacking and further improving the stacking capacity of the pallet cart.

[0030] In some embodiments, an L-shaped reinforcing plate 43 is provided between the insertion rod 42 and the frame 1, which can strengthen the connection strength between the insertion rod 42 and the frame 1, improve the pressure resistance when the insertion rod 42 and the stacking bowl 41 are plugged in, and thus improve the stability of the pallet cart during stacking.

[0031] In some embodiments, the overall height of the insertion rod 42 when inserted into the stacking bowl 41 is greater than the height of the moving device 7, which can avoid the shaking caused by the insertion rod 42 and the stacking bowl 41 not being properly inserted during stacking of the pallet trolley, thereby improving the stability during stacking.

[0032] A moving device 7 is provided at the bottom of the frame 1, and the moving device 7 includes two fixed wheels 71 and two universal wheels 72. The universal wheels 72 may be equipped with a brake locking device to achieve the stationary state of the pallet trolley; the two fixed wheels 71 and the two universal wheels 72 are symmetrically arranged at the bottom of both sides of the frame 1. Through the reasonable configuration of the fixed wheels 71 and the universal wheels 72, the pallet trolley is more flexible and stable during the transportation process.

[0033] The specific working principle is as follows:

[0034] When recycling the pallet trolley, first lock the moving device 7 to fix the pallet trolley, start the forklift, pass the fork rod on the forklift through the two shovel feet 6 at the bottom of the other pallet trolley to limit the movement of the pallet trolley during stacking, and match the stacking bowl 41 of the other pallet trolley with the plug rod 42 on the fixed pallet trolley one by one, and then move the fork rod out to achieve stacking of the pallet trolleys. When multi-layer stacking is required, repeat the above actions to achieve multi-layer stacking of the pallet trolleys.

[0035] When materials need to be transferred, the traction trailer 51 on one pallet trolley is connected to the hook 52 on another pallet trolley to connect multiple pallet trolleys end to end. Through the handrail 3 on the front pallet trolley, a thrust or pull force is applied to the multiple pallet trolleys, thereby realizing the linkage transfer of multiple pallet trolleys and improving the transfer efficiency.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
