Abstract
The invention discloses a folding device which comprises more than two folding bodies, at least one connecting body and more than two connecting shafts. Two ends of the connecting body are in hinge connection with the folding bodies and a plurality of folding devices are connected by the connecting shafts. The two ends of the connecting body of the folding device are respectively in the hinge connection with the folding bodies, and the plurality of folding bodies and the connecting bodies can be in the hinge connection in a spaced repeated way. Meanwhile, the plurality of folding devices can be connected with one another by the connecting shafts. When the folding bodies and the connecting bodies extend in a straight line state, the mutual torsion among a connecting body and a folding body which are adjacent is utilized and converted to a bearing force of the corresponding folding device to bear weights. When the folding device is bent and stored, the space usage of the folding device can be reduced to a large extent. The folding device can be bent and stored to reduce the space usage so as to enable the carrying to be convenient, can also extend for use so as to be changed to tools with various forms, such as ladders, working platforms and lap joint beams in case of bridge or road breakage.
Description
Technical field
The present invention relates to a kind of folding device, particularly a kind of by self folding dwindle take up room, portable folding device.
Background technique
Existing stage, worktable place mat plate often all are monoblocks on the market, and so both waste material was inconvenient to again take in, and some is folding also just to realize doubling, can not further roll over for a short time, take a large amount of accommodation spaces;
When natural disaster causes bridge, road to interrupt or during fracture, squad often needs earlier beam column or the crossbeam of overlap joint monoblock to connect road, and the beam column of monoblock or crossbeam take up room greatly, carries very inconveniently, influences 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 short length, as " people " word ladder or folding ladder repeatedly, these still take bigger 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 influence fire fighting opportunity or climb efficient.
Summary of the invention
The purpose of this invention is to provide a kind of folding device.
According to an aspect of the present invention, provide a kind of folding device, comprised and amount to body, at least one connecting body and two above coupling shafts more than two.
The cross section of amounting to body is U-shaped, amounts to body and is provided with at least one hole, and the two ends of connecting body are inserted in respectively in two U-shaped frames of amounting to body, and amounts to body and is articulated and connected.
One end of coupling shaft is fixed in the hole of amounting to body, and the other end of coupling shaft is fixed in the hole of amounting to body of another folding device.
The two ends of connecting body of the present invention are articulated and connected with amounting to body respectively, a plurality ofly amount to body and a plurality of connecting body can repeat to be articulated and connected at interval, simultaneously, can interconnect by coupling shaft between a plurality of folding devices; When amounting to body and connecting body extension linear state, utilize link and the mutually stubborn power between the body of amounting to is transformed into the supporting force of folding device, the support weight, when folding device is tortuous when taking in, less folding device takes up room largely, folding device can tortuously be taken in, minimizing takes up room, and is easy to carry, can extend use again, and develop into the instrument of variform, the overlap joint beam during as ladder, working platform, bridge or road fracture.
In some embodiments, the two ends of connecting body can be provided with projection, connecting body when amounting to the body linear state, amount to the U-shaped frame of body inside can be provided with the projection coupling recess.Thus, connecting body is when amounting to the body linear state, and the recess of amounting to the U-shaped frame of body inside snaps onto on the projection of connecting body, can guarantee to amount to body and connecting body is difficult for relatively rotating.
In some embodiments, the quantity of amounting to body can be N, and the quantity of connecting body can be M, and N is the natural number more than 3, and M is the natural number more than 2, amounts to body and connecting body and is articulated and connected at interval successively.Thus, the length in the time of can lengthening the folding device linear state, improve folding device speedily carry out rescue work, utilization ratio when the disaster relief, mountain-climbing.
In some embodiments, a plurality of folding devices can walk abreast and arrange.Thus, parallel the arrange instrument that can develop into variform such as stage of a plurality of folding devices that connect by coupling shaft, working platform, lifesaving platform (underlying air bag) use.
In some embodiments, connecting body with amount to the two ends that body is connected and can be circular-arc.Thus, can guarantee connecting body and amount to body and rotate smooth and easy mutually.
