Description

Technical Field

[0001] The utility model belongs to the technical field of carts and relates to a household folding storage push-pull cart. Background Art

[0002] A foldable storage cart is a cart that can be folded to reduce its size for easy carrying and storage. Existing household foldable storage carts only have a partially foldable or detachable structure, while the wheels and handles cannot be folded or detached. This results in an uneven shape after folding, and protruding parts that affect nearby items. Therefore, in order to ensure a regular appearance after folding, it is necessary to design a household foldable storage cart. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to provide a household folding storage push-pull cart.

[0004] The objectives of the present utility model can be achieved through the following technical solutions: A household foldable storage push-pull cart, comprising a push-pull cart body, characterized in that baffle one, baffle two, baffle three and baffle four are rotatably installed on the top of the push-pull cart body, and baffle one, baffle two, baffle three and baffle four are connected in sequence by a snap-fit ​​structure, a handle is rotatably installed on the side of the push-pull cart body, and a sliding member is rotatably connected to the bottom of the handle, and the sliding member is slidably installed in a sliding bin at the bottom of the push-pull cart body, and two sets of pulley groups are fixedly installed symmetrically on the bottom of the push-pull cart body, and the pulley group includes a rotating shaft, which is installed on the bottom of the push-pull cart body through a fixing member, and the rotating shaft can rotate on the fixing member, and universal wheels are fixedly installed at both ends of the rotating shaft.

[0005] The working principle of the present invention is as follows: when we need to use the push-pull cart, we turn over the pulley group and the handle from the bottom of the push-pull cart body and pull them out in sequence, then turn up the baffles 1, 2, 3 and 4 on the top of the push-pull cart body and fix them together through the snap structure, so as to complete the overall deployment of the push-pull cart; when we do not need to use the push-pull cart, we separate the baffles 1, 2, 3 and 4 and fold them inward in sequence, then rotate the handle and put it into the sliding compartment through the sliding part, and finally turn over the pulley group and put it away, so that the push-pull cart as a whole becomes a more regular rectangular parallelepiped.

[0006] A handle is also fixedly installed on the side of the push-pull cart body.

[0007] The above structure makes it convenient to move the push-pull cart by the handle after it is folded and stored.

[0008] A damping structure is provided at the connection between the handle and the sliding part. The damping structure includes a cylinder with a coil spring placed inside. One end of the coil spring is fixedly connected to the cylinder, and a steel ball is rotatably installed on the other end of the coil spring. A gasket is placed at the sealing end of the cylinder, and damping oil is filled in the cylinder.

[0009] With the above structure, the damping size is adjusted by adjusting the rolling resistance of the steel ball, and any angle adjustment is achieved in conjunction with the spring under the action of the damping oil.

[0010] The handle adopts a telescopic rod structure.

[0011] The above structure ensures the length requirement while being conveniently stored in the sliding compartment.

[0012] A cover plate is installed at the middle section of the rotating shaft, and tension spring structures are installed on the rotating shafts on both sides of the cover plate. A storage bin is provided at the bottom of the push-pull vehicle body at a position corresponding to the cover plate.

[0013] With the above structure, a small storage space is formed by the cover plate and the storage compartment, which is used to place items such as straps or fixing ropes, and its opening and closing are assisted by the tension spring structure.

[0014] The baffle plate 2 and the baffle plate 4 are provided with grip grooves.

[0015] Adopting the above structure makes it easy to open.

[0016] Compared with the existing technology, this household folding storage push-pull cart has the following advantages: the utility model adds more foldable and flippable storage structures on the basis of the existing household folding storage push-pull cart structure, ensuring normal transportation effect while making it easy to store after use. The shape after folding is more regular and does not take up space. BRIEF DESCRIPTION OF THE DRAWINGS
