[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] Reference Figures 1 to 3 The utility model provides a steel shopping cart anti-sliding mechanism: comprises a storage frame 1, two support frames 2 are fixedly provided at the bottom of the storage frame 1, two brake structures 3 are fixedly provided at the bottom of the two support frames 2, the brake structure 3 comprises a cylinder 301 fixedly installed with the bottom of the support frame 2, a spring 302 is fixedly provided on the top inner wall of the cylinder 301, a vertical rod 304 is movably provided on the bottom inner wall of the cylinder 301, a circular hole is provided on the bottom inner wall of the cylinder 301, a sealing ring is provided on the inner wall of the circular hole, the inner wall of the sealing ring is fitted with the vertical rod 304, the bottom end of the vertical rod 304 is fixedly connected to the top of the universal wheel 4, mounting plates 305 are fixedly provided on both sides of the cylinder 301, and a mounting cylinder 304 is fixedly provided at the bottom of the mounting plate 305 06. An insert rod 307 is fixedly arranged in the installation tube 306. A friction plate 308 is fixedly arranged at the bottom of the insert rod 307. A rubber sheet is fixedly arranged at the bottom of the friction plate 308. A spherical protrusion is arranged at the bottom of the rubber sheet. The thickness of the rubber sheet is three centimeters. A universal wheel 4 is fixedly arranged at the bottom of the brake structure 3. Two connecting plates 5 are fixedly arranged on one side of the storage frame 1. An inclined rod 6 is fixedly arranged on the two connecting plates 5. A same grip rod 7 is fixedly arranged between the two inclined rods 6. The brake structure 3 is set to automatically stop the vehicle when the weight exceeds the specified weight. It can not only limit the user from overweight items and protect the vehicle frame, but also prevent the user from sliding on the vehicle, thereby improving the safety of vehicle use.

[0026] Reference Figure 3 In order to achieve the purpose of smooth lifting of the guide plate 303, the guide plate 303 is fixedly provided at the bottom of the spring 302, and two slide grooves are provided on the inner wall of the cylinder 301. Slide blocks are fixedly provided on both sides of the guide plate 303, and the slide blocks and the slide grooves are movably connected. When the vehicle is pressed down, the guide plate 303 drives the slide blocks to move in the slide grooves, which can prevent the guide plate 303 from being stuck and unable to move;

[0027] Reference Figure 2 In order to increase the points of contact between the shopping cart and the ground, a support rod 8 is fixedly provided on one side of the storage frame 1, and two cross bars 9 are fixedly provided at the bottom end of the support rod 8. Both ends of the two cross bars 9 are fixedly provided with rollers 10. When a user lies on the shopping cart and the vehicle has a tendency to roll over, the two rollers 10 contact the ground to provide support for the vehicle, which can effectively prevent the vehicle from rolling over.

[0028] Working principle: the weight limit of the storage frame 1 is 30 kilograms. When the goods in the storage frame 1 are greater than 30 kilograms, the multiple springs 302 are compressed to the extreme, and the friction plate 308 contacts the ground, and the vehicle cannot continue to move, which can protect the vehicle and prevent the goods from being too heavy and squeezing and deforming the storage frame 1. During the use of the vehicle, if the user lies on the vehicle and slides, the weight of the person is applied to the vehicle, and the multiple universal wheels 4 move upward, the universal wheels 4 squeeze the vertical rod 304, and the vertical rod 304 drives the guide plate 303 to move upward. The guide plate 303 squeezes the spring 302. At this time, the friction plate 308 moves to a position close to the ground and contacts the ground, and the vehicle cannot continue to slide, which can effectively prevent the user from lying on the car and sliding. Since the weight of the person is applied to one side of the vehicle, there is a risk of rollover. The coordinated use of the two rollers 10 and the support rod 8 can increase the contact points between the vehicle and the ground, thereby effectively preventing the shopping cart from rolling over.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
