[0027] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0028] Embodiment:

[0029] Please combine Figures 1-5 , A simple trolley structure of this embodiment includes a bearing frame 1. Both ends of the bearing frame 1 are fixedly connected with mounting plates 2. The bottom of the mounting plate 2 is installed with universal wheels 3 through bolts. The upper end of the bearing frame 1 is fixedly connected with a connecting plate 4. The inner wall of the mounting plate 2 is fixedly connected with a diagonal brace plate 5. One end of the diagonal brace plate 5 away from the mounting plate 2 is fixedly connected with an auxiliary handle 6. The bottom of the bearing frame 1 is fixedly connected with an extension rod 7. The inner wall of the extension rod 7 is rotatably connected with a rotating rod 8. Both ends of the rotating rod 8 are fixedly connected with connecting sleeves 9. One end of the connecting sleeve 9 is fixedly connected with a reinforced wheel 10. The purchased items are placed through the bearing frame 1. By pushing the auxiliary handle 6, the universal wheels 3 are moved, so that the rotating rod 8 rotates inside the extension rod 7, driving the connecting sleeve 9 to rotate, so that the reinforced wheel 10 moves, and the overall position is moved. Through the universal wheels 3, the whole can turn freely. The load-bearing capacity of the trolley is significantly improved by the iron universal wheels 3 and the reinforced wheels 10, ensuring stability even when carrying heavy items. The stability of the trolley during movement is enhanced by the reinforced wheels 10.

[0030] Both ends of the connecting plate 4 are installed with storage frames 11 through bolts. The storage frames 11 are located at the rear end of the bearing frame 1. Through the storage frames 11 at the rear end of the bearing frame 1, items such as backpacks carried by users can be stored or purchased items can be stored, increasing the storage space for items, improving the practicability, and enhancing the user experience.

[0031] The inner wall of the inclined support plate 5 is threadedly connected with fastening screws 12. The fastening screws 12 penetrate through the inclined support plate 5 and are threadedly connected with the inner wall of the connecting plate 4. The number of connecting plates 4 is set to two, and the two connecting plates 4 are symmetrically distributed with the bearing frame 1 as the center. The number of inclined support plates 5 corresponds to that of the connecting plates 4.

[0032] The surface of the auxiliary handle 6 is provided with an anti-slip sleeve. The auxiliary handle 6 is located at the upper end of the storage frame 11. Through the anti-slip sleeve design on the surface of the auxiliary handle 6, the friction during gripping is increased, preventing the hand from sliding, and improving the comfort and safety during use.

[0033] The number of universal wheels 3 is set to two, and the two universal wheels 3 are symmetrically distributed with the bearing frame 1 as the center.

[0034] The number of reinforced wheels 10 is set to two, and the two reinforced wheels 10 are symmetrically distributed with the bearing frame 1 as the center.

[0035] The universal wheels 3 are located at the front end of the reinforced wheels 10. Both the universal wheels 3 and the reinforced wheels 10 are made of iron.

[0036] The implementation principle of a simple trolley structure in the embodiment of the present application is as follows: When in use, the purchased items are placed on the bearing frame 1. By pushing the auxiliary handle 6, the universal wheels 3 move, causing the rotating rod 8 to rotate inside the extension rod 7, driving the connecting sleeve 9 to rotate, causing the reinforced wheels 10 to move, and thus moving the overall position. Through the universal wheels 3, the whole can turn freely. The iron universal wheels 3 and reinforced wheels 10 significantly improve the load-bearing capacity of the trolley, ensuring stability even when carrying heavy items. The reinforced wheels 10 enhance the stability of the trolley during movement, and at the same time have high strength and wear resistance, extending the service life. Through the anti-slip sleeve design on the surface of the auxiliary handle 6, the friction during gripping is increased, preventing the hand from sliding, and improving the comfort and safety during use. Through the storage frames 11 at the rear end of the bearing frame 1, items such as backpacks carried by users can be stored or purchased items can be stored, increasing the storage space for items, improving the practicability, and enhancing the user experience.

[0037] The above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model shall fall within the scope of protection required by the present utility model.
