[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a trolley with a reinforced structure, comprising a frame 1, a handlebar 2 is fixedly installed on the top of the frame 1, a wheel 3 is arranged at the bottom of the frame 1, and a support mechanism 4 for improving the stability of the trolley is arranged on the frame 1. By setting the support mechanism 4, the stability of the frame 1 can be enhanced to avoid displacement of the frame 1 when the staff is loading and unloading goods, thereby facilitating the staff to load and unload goods. A protective mechanism 5 is arranged on the support mechanism 4. By setting the protective mechanism 5, a fence can be formed on the periphery of the frame 1 to avoid objects falling from the frame 1 during the movement of the trolley, thereby enhancing the safety of the frame 1.

[0024] The supporting mechanism 4 comprises a rotating drum 41, a supporting rod 42, a worm 43, a worm wheel 44, a spiral groove 45, a supporting plate 46, a telescopic rod 47 and a handle 48; the rotating drum 41 is rotatably connected to the bottom of the frame 1, a worm wheel 44 is fixedly mounted on the outer wall of the rotating drum 41, a spiral groove 45 is provided on the rotating drum 41, and two groups of rotating drums 41 are arranged, and the two groups of rotating drums 41 are mirror-imaged and arranged on both sides of the worm 43 with the worm 43 as the central axis, and the outer walls of the two groups of rotating drums 41 are both fixedly mounted with worm wheels 44, and the worm wheels 44 on the two groups of rotating drums 41 are both meshed with the worm 43, and the spiral grooves 45 on the two groups of rotating drums 41 are in opposite directions, and the outer wall of the supporting rod 42 is attached to the inner wall of the spiral groove 45, and the two groups of rotating drums 41 rotate synchronously in opposite directions while the spiral groove 45 will synchronously squeeze the supporting rod 42, and support plates 46 are fixedly mounted on both ends of the supporting rod 42, and the spiral grooves 45 are arranged on the two ends of the supporting rod 42. The two groups of support plates 46 can provide stable support for the frame 1, enhance the stability of the frame 1, and prevent the frame 1 from being displaced when the staff are loading and unloading goods. A telescopic rod 47 is fixedly installed on the upper surface of the support plate 46, and the end of the telescopic rod 47 away from the support plate 46 is fixedly installed on the bottom of the frame 1. When the spiral groove 45 squeezes the support rod 42, under the guiding action of the telescopic rod 47, the support rod 42 will drive the two groups of support plates 46 to move up and down, one end of the worm 43 is rotatably connected to the bottom of the frame 1, and the other end of the worm 43 passes through the frame 1 and is fixedly installed with a handle 48. The worm 43 is rotatably connected to the penetration point of the frame 1, and the worm 43 is meshed with the worm wheel 44. The worm 43 is rotated by the handle 48, and the rotation of the worm 43 and the two groups of worm wheels 44 meshed with it can drive the two groups of rotating drums 41 to rotate synchronously in opposite directions.

[0025] The protective mechanism 5 includes a connecting rod 51 and a protective cover 52; the connecting rod 51 is fixedly mounted on the side wall of the support plate 46, and a protective cover 52 is fixedly mounted on one end of the connecting rod 51 away from the support plate 46, and the inner wall of the protective cover 52 is attached to the side wall of the frame 1. The protective cover 52 can be used to form a fence around the frame 1 to prevent items from falling from the frame 1 during the movement of the trolley, thereby enhancing the safety of the frame 1.

[0026] Working principle: when it is necessary to load and unload goods on the frame 1, first rotate the worm 43 through the handle 48. The rotation of the worm 43 and the two sets of worm wheels 44 meshing with it can drive the two sets of rotating drums 41 to rotate synchronously in opposite directions. At this time, the spiral grooves 45 in opposite directions on the two sets of rotating drums 41 will synchronously squeeze the support rods 42 downward. At this time, under the guidance of the telescopic rod 47, the support rods 42 will drive the two sets of support plates 46 to move downward until the support plates 46 are attached to the ground and the wheels 3 are suspended. At this time, the two sets of support plates 46 can be used to stably support the frame 1, enhance the stability of the frame 1, and avoid displacement of the frame 1 when the staff are loading and unloading goods, thereby facilitating the staff to load and unload goods.

[0027] During the downward movement of the support plate 46, the connecting rod 51 can drive the protective cover 52 to move downward synchronously. When the support plate 46 lifts the frame 1, the worm 43 can be stopped until the top of the protective cover 52 is flush with the upper surface of the frame 1. By making the protective cover 52 flush with the frame 1, it is convenient for the staff to load and unload goods. When the support plate 46 moves upward and breaks away from the support of the frame 1, the connecting rod 51 can drive the protective cover 52 to move upward synchronously, so that the protective cover 52 can protrude from the frame 1. At this time, the protective cover 52 can form a fence around the frame 1 to prevent items from falling from the frame 1 during the movement of the trolley, thereby enhancing the safety of the frame 1.

[0028] 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.
