Abstract

The utility model discloses a folding device. The folding device comprises more than two folding bodies, at least one connector and more than two connecting shafts, wherein both ends of the connector are hinged and connected to the folding bodies. A plurality of folding devices are connected through connecting shafts. According to the folding device, both ends of the connector are respectively hinged and connected to the folding bodies, a plurality of folding bodies and a plurality of connectors can be repeatedly hinged and connected at intervals, and meanwhile, the folding devices can be connected through the connecting shafts; when the folding bodies and the connectors extend to be in a linear state, a torque force between the connectors and the folding bodies is converted into a bearing force of the folding devices for bearing heavy goods; when the folding device is bent for storage, the occupied space of the folding device can be greatly reduced; since the folding device can be bent for storage, the occupied space is reduced, and the device is convenient to carry, also can extend for use and can be converted into various types of tools such as ladders, working platforms and lapping beams when bridges or roads are ruptured.

Description

Folding device

Technical field

The utility model relates to a kind of folding device, particularly a kind of by self folding dwindle take up room, portable folding device.

Background technique

On market, existing stage, worktable place mat plate are all often monoblocks, have so both wasted material, are inconvenient to again take in, and some is folding also just realizes doubling, can not further roll over littlely, take a large amount of accommodation spaces;

When natural disaster causes bridge, road to interrupt or during fracture, beam column or crossbeam that squad often needs first to overlap monoblock are connected road, the beam column of monoblock or crossbeam take up room greatly, carry very inconveniently, affect efficient and the speed of speedily carrying out rescue work;

Existing folding ladder generally adopts the method that shortens length, very long ladder is folded into shorter length, as " people " word ladder or folding ladder repeatedly, these still take larger space (can't tortuously fold) through the folding ladder of one or many, when particularly these folding ladders are used for fire-fighting or climbing, still inconvenient when fire personnel or climbing person carry, thus affect fire fighting opportunity or climb efficient.

The model utility content

The purpose of this utility model is to provide a kind of folding device.

According to an aspect of the present utility model, a kind of folding device is provided, comprise and amount to body, at least one connecting body and two above coupling shafts more than two.
