Description

Technical Field

[0001] This utility model relates to the field of handcart technology, specifically a lightweight folding handcart. Background Technology

[0002] The terrain for some tobacco delivery routes is mainly mountainous and hilly, with narrow urban roads and concentrated retail customers in farmers' markets, vegetable markets, and shopping malls. Due to road traffic control, roadblocks, and no-parking restrictions, delivery vehicles are often far from stores, resulting in many situations where delivery vehicles cannot reach the stores. This often leads to delivery personnel making multiple trips to pick up and deliver cigarettes by hand, which is time-consuming and laborious. At the same time, as the number of customers continues to grow, the labor intensity of delivery is constantly increasing, and delivery time is generally extended by about 2 hours.

[0003] In the cigarette delivery process, delivery personnel primarily rely on carrying cigarettes by hand to deliver them to customers' homes. However, in some urban delivery routes, due to the large size of delivery vehicles and the difficulty of turning around in narrow roads and alleys, coupled with traffic control, roadblocks, and no-parking restrictions, delivery vehicles often park in safe areas far from retail outlets, requiring delivery personnel to walk to the stores to deliver the cigarettes. Because delivery personnel can only carry a limited number of cigarette packs at a time, when customer orders are large, they need to make multiple trips, resulting in low delivery efficiency. With the increasing number of retailers on various urban delivery routes and seasonal fluctuations in cigarette sales, the potential for decreased delivery efficiency and service quality increases as the walking distance and number of trips per customer increase.

The rainproof cloth 11 is used to block rainwater. A pull rod 7 is installed in the middle of the bottom end of one main body 1. The pull rod 7 is used for pulling by hand.

[0026] In this invention, two base plates 2 are movably connected to the bottom of two main bodies 1. The width of the base plates 2 is greater than the length of conventional tobacco, which facilitates the stacking of tobacco. Two sets of first movable rods 3 and second movable rods 4 are provided on both sides of the main bodies 1. The first movable rods 3 and second movable rods 4 are movably connected in a cross manner, and one end of the first movable rod 3 is movably connected to one side of the main body 1. The common end of the second movable rod 4 is movably connected to the common end of the two base plates 2. When the first movable rods 3 and second movable rods 4 are open, they form an X-shape and are limited by a limiting rod 5 to maintain the overall open state of the device. The main bodies 1, base plates 2, first movable rods 3 and second movable rods 4 form a placement space for stacking multiple tobaccos. A pull rod 7 installed on one end of the main body 1 facilitates hand pulling, and a moving wheel 6 installed at the bottom of the main body 1 facilitates the device's movement. The device is designed for overall movement. When tobacco is not needed, it can be folded and stored using the foldable first movable rod 3 and second movable rod 4, facilitating overall folding and transportation. Several sets of matching telescopic belts 8 and clamping blocks 9 are installed on the first movable rod 3 and second movable rod 4. When the tobacco stack exceeds the height of the main body 1, the free end of the telescopic belt 8 loops around the tobacco and is clamped in the clamping block 9. In the event of bumps or sudden stops, the tobacco is restrained to prevent it from falling off, thereby increasing the quantity of tobacco delivered. If it rains during the tobacco delivery process, the rain cover 11 on the roll rod 10 is pulled out, allowing the hook 12 to match and clamp onto the hook plate 13. The rain cover 11 protects the covered tobacco from rain, preventing it from getting wet and ensuring the delivery efficiency and quality of a large quantity of tobacco. The device is highly effective.
