Technical Field

[0001] The present invention relates to the technical field of trolley equipment, and in particular to a lightweight trolley with high portability. Background Art

[0002] A trolley is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of trolleys continues to develop, trolleys are still used as an indispensable transport tool. Trolleys are widely used in production and life because they are low in cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use, and are very convenient for transporting lighter items over short distances.

[0003] There are single-wheeled carts, two-wheeled carts, three-wheeled carts and four-wheeled carts. Single-wheeled carts can travel on narrow springboards, temporary bridges and goat paths, can turn on the spot, and are very convenient for unloading goods; commonly used two-wheeled carts include hand-pushed carts for carrying pieced items, rack carts and bucket carts for carrying bulk materials; three-wheeled carts have one, and four-wheeled carts have two swivel casters that can rotate around a vertical axis; such swivel casters can automatically adjust to the direction with the smallest running resistance as the direction of vehicle movement changes during operation, but in actual applications, four-wheeled carts are the most widely used, while in the current existing technology, carts can only be used for moving, and most of the hand-pushed carts are fixed and cannot be changed in shape, resulting in a small scope of application, and the traditional hand-pushed carts do not have the function of folding, and will occupy a large space, but with the continuous improvement of people's requirements for quality of life, the lightness, portability and diversification of handcarts have become more people's expectations for handcarts, and thus a lightweight handcart with high portability is needed to solve this problem. Summary of the invention

[0004] The object of the present invention is to provide a lightweight trolley with high portability to solve the problems raised in the above-mentioned background technology.

[0024] refer to Figures 1 to 3Embodiment 1 is described, comprising a cart base 1, both sides of the cart base 1 are penetrated by a rotating rod 16, and the symmetrical ends of the rotating rods 16 on both sides are provided with stoppers 15 for easy rotation and adjustment, four stoppers 15 are provided and distributed on the cart base 1 and then connected by a second steel wire rope 14, and the other ends of the second steel wire rope 14 at the upper and lower ends are connected to the adjustment block 12, and the adjustment blocks 12 at both ends are rotated by the first folding knob 9 and the second folding knob 10 respectively, a stopper 8 is provided on one side of the cart base 1, and a hand push is provided on the side of the cart base 1 away from the stopper 8 Rod 6, a storage plate 2 is fixedly installed on the cart base 1, and two slots 5 of different sizes are provided on the storage plate 2, a stopper 15 is located in an arc groove 17 at both sides of the cart base 1, the arc groove 17 passes through a rotating rod 16, and the stopper is sleeved on the rotating rod 16 at both sides of the cart base 1, a connecting block 18 is fixedly installed at the bottom end of the stopper 15, and a first U-shaped frame 19 is fixedly installed at the bottom end of the connecting block 18, a moving wheel 20 is provided in the first U-shaped frame 19, and the moving wheel 20 is rotatably connected to the first U-shaped frame 19 through a rotating shaft 21;

[0025] In this embodiment, the first folding knob 3 and the second folding knob 4 drive the second steel wire rope 14 at both ends to adjust the rotation of the limit member 15, thereby realizing the tightening and unfolding of the moving wheel 20, which is convenient for folding the entire trolley and easy to store.

[0026] Example 2

[0027] refer to Figure 2 and Figure 4 Example 2 is described. This embodiment further describes Example 1, including a hand grip 7 installed on the hand push rod 6, the hand grip 7 is made of silicone material, and the bottom end of the hand grip 7 is installed on a wave meshing button 9 that is easy to press, the two side ends of the wave meshing button 9 are respectively connected to the first steel wire rope 10, and the bottom ends of the first steel wire rope 10 at the two side ends are connected through a regulating joint 11, the regulating joint 11 is installed on a U-shaped sleeve 24, the U-shaped sleeve 24 is sleeved on the second U-shaped frame 23 and rotatably connected to each other, and the second U-shaped frame 24 is provided with four side ends distributed on two rotating rods 16, the hand push rod 6 is in the U-shaped sleeve 24, and an extension rod 22 is provided between the second U-shaped frame 23 and the rotating rod 16, and the extension rod 22 is rotatably connected to the second U-shaped frame 23 through a rotating shaft 21, and the second U-shaped frame 23 arranged on the side of the rotating rod 16 away from the hand push rod 6 is fixedly connected with a stopper 8;

[0028] In this embodiment, the wave engagement button 9 is set to adjust the looseness of the first steel wire rope 10 and the adjustment joint 11 to achieve the contraction and expansion of the push rod 6. When the block 8 and the push rod are in the contracted state, the flatness of the upper and lower surfaces after folding can be ensured to facilitate the stacking of furniture.
