Description

High-bearing foldable carrier

Technical Field

The utility model relates to a carrier technical field, concretely relates to collapsible carrier that height bore.

Background

The cargo carrying plate vehicle is used as a portable cargo carrying tool, is convenient to use and convenient to carry, and is widely used, such as material conveying of a factory, home delivery and picking of goods of a logistics company, goods pulling and picking of goods of a business super, and carrying of goods and living goods which are slightly heavy in civilian life. The common cargo carrying plate vehicle is made of foldable metal, and the common cargo carrying plate vehicle is roughly divided into a type that a cargo carrying surface is a metal flat plate and a type that the cargo carrying surface is a hollow square tube. Still another plate trailer adopts the form that metal combines with plastics, also can fold the handle. The carrier on the current market has the following shortcomings:

1. The research on some goods carrying plate carts sold in the market shows that many products also have the folding function, the folding mode is still not ideal, and some carts are small and exquisite after being folded, but the actual use of the unfolded carts is small in carrying area, so that the carts cannot be used when carrying more goods. The plate trailer with a larger loading area can meet the requirement of loading, but the plate trailer with a larger volume after being folded becomes difficult to carry. And it is inevitable to go into narrow spaces during use, and the large pallet truck is clumsy.

2. Some retractable plate trolleys are also available on the market, and the retractable size is not large, so that the cargo carrying area can be slightly increased. Moreover, many cargo-carrying plate trucks are made of plastics and profiles, the strength is not high enough, and some industrial plate trucks are made of steel plates, although firm, can have a certain weight, and basically can only be used in workshops, but cannot meet various use occasions in life.

3. the handles of the pallet truck are basically vertical, and are slightly bent, so that the force cannot be completely applied to the bottom of the pallet truck when heavy load is pulled, the pallet truck is relatively labored to pull up, the root of the pull rod can be broken when the force is too large, and due to the vertical pull rod design, when a cargo is pulled, the heel of a cargo puller can be scratched carelessly, and potential safety hazards exist.
