Description

Technical Field

[0001] The utility model belongs to the technical field of toy vehicles, and particularly relates to an automatic anti-slip toy cart. Background Art

[0002] A toy cart generally includes a main frame, handrails and wheels. When pushing a cart, children generally hold the handrails to push the main frame forward or backward. However, when the cart is on a downhill section, more force is often needed to keep the cart at a stable speed. Especially when the cart has its own storage space and the storage space is filled with miscellaneous items, the weight of the cart increases and the external force required when going downhill is greater. When the child does not have enough control, the cart is prone to lose control and dive, posing certain safety hazards. Utility Model Content

[0015] like Figure 1 to Figure 2As shown: an automatic anti-slip toy cart, including a main frame 1, a hook-type carriage 3, a handrail 4 and wheels, the main frame 1 includes left and right side panels, a windshield 15 and a bottom plate 16 fixedly connected to the upper ends of the left and right side panels, the left and right side panels, the windshield 15 and the bottom plate 16 surround a cavity, the wheels are divided into a front wheel 5 and a rear wheel 2, the front wheel 5 is arranged outside the left and right side panels, a wheel axle 7 is fixedly arranged between the two front wheels 5, the two centers of the front wheel 5 are respectively fixed to the two ends of the wheel axle 7, the wheel axle 7 The two ends pass through the left and right side plates and are rotatably connected with the left and right side plates. The rear wheel 2 is rotatably connected to the outer side surface of the rear end of the main frame 1. The upper end of the main frame 1 is fixedly connected to the handrail 4, and the handrail 4 includes a left bracket, a right bracket and a cross bar 9. The left and right brackets are respectively fixedly connected to the left and right side plates. The two ends of the cross bar 9 are respectively fixedly connected to the left and right brackets by screws. The hook-type carriage 3 is a semi-open structure, and an opening is provided at one end close to the cavity. A protruding hook 14 is provided at the upper end of the hook-type carriage 3. Through the hook 14 The hook-type carriage 3 is hung on the crossbar 9 of the handrail 4; the inner walls of the left and right side panels below the bottom plate 16 are movably connected to the automatic anti-skid device, which includes a balance bar 13, a counterweight 11 and an anti-skid pad 10. The middle part of the balance bar 13 is rotatably connected to the inner walls of the left and right side panels through a pin or a bolt, and the counterweight 11 is fixedly arranged at both ends of the balance bar 13. The anti-skid pad 10 is arranged at the bottom of the counterweight 11 at the rear end of the balance bar 13. The total weight of the counterweight 11 and the anti-skid pad 10 is equal to The counterweight 11 at the other end of the balance bar 13 has the same weight, forming an automatic leveling balance structure. When the trolley is on a flat road section, since the weights at both ends of the balance bar 13 are equal, the balance bar 13 remains horizontal, and the counterweights 11 at both ends are suspended horizontally above the ground. When on a downhill section, the trolley is in a tilted state with the front of the vehicle facing downward. At this time, the counterweight 11 and the anti-skid pad 10 at the rear end of the balance bar 13 are attached to the ground, increasing the friction between the trolley and the ground, thereby playing the role of automatic braking and anti-slipping.

[0016] An impeller 6 is fixedly arranged on the outer surface of the middle section of the wheel shaft 7. The impeller 6 rotates coaxially with the front wheel 5. When there are debris on the traveling route, the debris is swept into the cavity by the impeller 6.

[0017] The front end of the bottom plate 16 is fixedly connected to the baffle 12, and the baffle 12 has an upslope surface and a downslope surface. The upslope surface is close to the front wheel 5 and is a concave ascending arc surface. The downslope surface is connected between the top of the upslope surface and the bottom plate 16. When the impeller 6 sweeps debris into the cavity, the debris falls into the cavity through the upslope and downslope surfaces of the baffle 12. When the cart is on a downhill section, the baffle 12 can prevent the debris in the cavity from falling out.

[0018] There are several cross bars 9, which are fixed to the handrails 4 at different heights by screws, and the hook-type carriage 3 can be fixed with any cross bar 9.

[0019] The upper surface of the windshield plate 15 is connected to a plurality of gears 8 by bolts. The gears 8 mesh with each other. When one gear 8 is rotated, the other gears are driven to rotate at the same time.

[0020] Directional words such as "left", "right", "up", and "down" in the present invention only refer to the directions in the drawings and cannot be used as limitations on the technical solutions of the present invention.
