[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a multi-functional handcart suitable for coal mining, which consists of a frame 1, a cargo box 2, wheels 3, a front baffle 102, a rear baffle 103, a limiting component 5, a storage box 4, and an assembly frame 104. It realizes multiple functions such as material transportation, emergency rescue, and tool storage, and significantly improves the safety and convenience of coal mining.

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] The frame 1 is the basic support structure of the handcart, consisting of a base frame 101, a front baffle 102, a rear baffle 103, and feet 6. The front baffle 102 and rear baffle 103 are welded to the front and rear sides of the base frame 101 respectively, forming a protective barrier to effectively prevent materials from sliding forward or backward during transport. The feet 6 are welded to the side of the base frame 101 near the rear baffle 103; when parked, they can be lowered to support the frame, preventing the handcart from sliding and enhancing parking stability.

[0026] As attached Figure 2 To be continued Figure 3 As shown: The rear support frame 103 consists of a connecting frame 1031 and a crossbar 1032. The connecting frame 1031 is welded to the base frame 101, and the crossbar 1032 is welded to the top of the connecting frame 1031. Several sets of insertion holes 7 are machined on the crossbar 1032, and each set of insertion holes 7 has a positioning hole 8 on its side for inserting a positioning pin 1033. The assembly frame 104 includes a straight ladder frame 1041 movably inserted into the connecting frame 1031. The straight ladder frame 1041 has pin holes adapted to the positioning pins 1033, and a curved handrail 1042 is welded to one end. When it needs to be converted into a stretcher trolley, the positioning pins 1033 are removed, the straight ladder frame 1041 is pulled out and inserted into the insertion holes 7 of the crossbar 1032, and fixed by the positioning pins 1033. At this time, the straight ladder frame 1041 and the cover plate 203 are on the same plane, forming a flat stretcher support surface. The curved handrail 1042 curves upwards at this time, making it easier for staff to carry and improving rescue efficiency.

[0027] As attached Figure 3As shown: The bucket 2 is fixed to the base frame 101 and consists of a bucket body 201 and a cover plate 203.
