[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a construction cart which is convenient for loading and unloading, comprising a frame 1, a cargo bucket 2 being hinged on the top of the frame 1, a rotating shaft 3 being fixedly installed on the bottom of the frame 1, a wheel 4 being rotatably connected to the outer wall of the rotating shaft 3, a unloading mechanism 5 for convenient unloading being provided on the frame 1, by means of which the cargo inside the cargo bucket 2 can be quickly unloaded, a limiting mechanism 6 for improving the stability of the frame 1 being provided on the frame 1, by means of which the wheel 4 can be limited, so as to prevent the frame 1 from moving during the rotation and unloading of the cargo bucket 2, thereby keeping the frame 1 in a stable state.

[0023] The unloading mechanism 5 comprises a threaded rod 51, a connecting rod 52, a connecting rod 53, a handle 54 and a sliding rod 55; one end of the threaded rod 51 is rotatably connected to the inner wall of the frame 1, the other end of the threaded rod 51 penetrates the frame 1 and is fixedly installed with a handle 54, the threaded rod 51 is rotatably connected to the penetration of the frame 1, the inner wall of the frame 1 is slidably connected with the sliding rod 55, the inner wall of the sliding rod 55 is threadedly connected to the outer wall of the threaded rod 51, the threaded rod 51 is rotated by the handle 54, and the rotation of the threaded rod 51 can drive the The threaded sliding rod 55 slides on the inner wall of the frame 1, and the connecting rod 52 is fixedly installed at the bottom of the cargo box 2. One end of the connecting rod 53 is hinged on the inner wall of the sliding rod 55, and the other end of the connecting rod 53 is hinged on the bottom of the connecting rod 52. When the sliding rod 55 gradually approaches the handle 54, the sliding rod 55 will pull the connecting rod 53, so that the connecting rod 53 pulls the connecting rod 52. When the connecting rod 53 pulls the connecting rod 52, it will drive the cargo box 2 to rotate, and the goods inside the cargo box 2 can be poured out through the rotation of the cargo box 2.

[0024] The above-mentioned limiting mechanism 6 includes a screw rod 61, a knob 62, a limiting pin 63, and a limiting hole 64; the screw rod 61 is threadedly connected to the inner wall of the frame 1, and the screw rod 61 passes through the frame 1, one end of the screw rod 61 is fixedly installed with a knob 62, and the other end of the screw rod 61 is fixedly installed with a limiting pin 63. The screw rod 61 is rotated by the knob 62, and the limiting pin 63 can be driven to move parallel to the screw rod 61 under the threaded connection between the screw rod 61 and the frame 1. A limiting hole 64 is provided on the wheel 4, and there are multiple groups of limiting holes 64. The multiple groups of limiting holes 64 are arranged in a circular array on the wheel 4 with the rotating shaft 3 as the center point. The spacing between the limiting hole 64 and the rotating shaft 3 is equal to the spacing between the limiting pin 63 and the rotating shaft 3. The limiting pin 63 is inserted into the inside of the limiting hole 64. At this time, the wheel 4 can be limited by the limiting hole 64, the limiting pin 63 and the screw rod 61, so as to prevent the frame 1 from moving during the rotation and unloading of the cargo bucket 2.

[0025] Working principle: when the goods in the cargo box 2 need to be unloaded, the threaded rod 51 is rotated by the handle 54. The rotation of the threaded rod 51 can drive the sliding rod 55 threadably connected thereto to slide on the inner wall of the frame 1, and make the sliding rod 55 gradually approach the handle 54. At this time, the sliding rod 55 will pull the connecting rod 53, so that the connecting rod 53 pulls the connecting rod 52. When the connecting rod 53 pulls the connecting rod 52, it will drive the cargo box 2 to rotate. The rotation of the cargo box 2 can pour out the goods inside it, and the goods can be quickly unloaded, which is more convenient to use.

[0026] When it is necessary to unload the goods, the screw rod 61 is rotated by means of the knob 62. Under the threaded connection between the screw rod 61 and the frame 1, the limit pin 63 can be driven to move in parallel, and the limit pin 63 can be inserted into the inside of the limit hole 64. At this time, the wheel 4 can be limited by the limit hole 64 in conjunction with the limit pin 63 and the screw rod 61, so that the wheel 4 cannot rotate, thereby preventing the frame 1 from moving during the rotation of the cargo box 2 to unload the goods, and keeping the frame 1 in a stable state.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
