Multifunctional trolley with double-layer platform

Abstract

The invention discloses a multifunctional trolley with a double-layer platform, and belongs to the field of carrying tools. The trolley comprises an upper-layer platform body, a bottom-layer platformbody and a pushing hand, the pushing hand is fixed at the rear portion of the bottom-layer platform body, the upper-layer platform body is installed over the bottom-layer platform body through a scissor-type lifting mechanism, and the scissor-type lifting mechanism is further internally provided with an upper-layer locking air spring; the bottom-layer platform body comprises a bottom-layer platform fixing frame and a bottom-layer platform retractable frame which are retractably matched, the rear portion of the bottom-layer platform fixing frame and the front portion of the bottom-layer platform retractable frame are provided with rolling wheels, a bottom-layer retractable air spring for keeping the bottom-layer platform retractable frame elastically extending out is arranged between the bottom-layer platform fixing frame and the bottom-layer platform retractable frame, and the rear portion of the bottom-layer platform fixing frame is provided with a linkage mechanism for driving the bottom-layer platform retractable frame to retract back. By means of the trolley, the flexible use of the double-layer platform can be achieved; the loading capacity of the double-layer trolley is improved, and the trolley is flexible and convenient to use and easier to operate.

Description

technical field [0001] The present invention relates to a trolley, more specifically, to a multi-functional trolley with double-layer platforms. Background technique [0002] Now, many single-function product designs on the market can no longer meet people's growing living needs. Many products have single functions and no innovation. These products will only make people feel that they are a waste of resources, occupying space, and wasting money. Bring various inconveniences to people's life and work. Multi-functional design is to add some practical functions on the basis of single-function products. However, in the current market, there are many multi-functional products that have no actual practical value. They are designed and produced entirely for functions, and some multi-functional Products have no connection between their functions at all, resulting in a waste of functions. [0003] The handcart is a transport vehicle that is pushed and pulled by manpower, and it has...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of existing trolleys such as single function and poor loading capacity, and provide a multi-functional trolley with a double-layer platform. By adopting the technical solution of the present invention, the trolley has an upper and lower platform, and the upper platform can be used by scissors. The lifting mechanism and the upper platform locking gas spring control the lifting movement, so that the flexible use of the double-layer platform can be realized; the bottom platform has a telescopic bottom platform telescopic frame, and the bottom platform telescopic frame can be freely moved Controlling the extension and retraction of the bottom platform telescopic frame not only improves the loading capacity of the double-deck trolley, but also is flexible and convenient to use and easier to operate
