Description

A kind of fast folding expansion bracket
Technical field
The utility model relates to a kind of support frames more particularly to a kind of fast folding, and bracket is unfolded.
Background technique
Currently, (such as the disaster relief, field operation in use, especially urgent outdoor application outdoors of most of Medical Devices Deng), being typically necessary support frame is supported, for example, Portable X X-ray machine X and its detector etc..
Existing majority support frame, though stability of strutting system can satisfy requirement, these support frames are often more heavy, Expansion, folding require to spend long period or even the more people's simultaneously operatings of some need, for example, a people maintains support frame to be unfolded State, another person carry out related locking operation, are unable to satisfy outdoor emergency application in this way, and carrying aspect, there is also difficulties.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of fast foldings, and bracket, this fast folding expansion is unfolded Bracket unfolded is simple and convenient, carries convenient for single, particularly suitable for outdoor use.The technical solution adopted is as follows:
Bracket is unfolded in a kind of fast folding, it is characterized in that: include first support, second support, at least two locking connecting rods, Multiple auxiliary locking mechanisms, first support and second support are arranged side by side, and each locking connecting rod assists locking mechanism to be connected to the Between one bracket and second support;First support, second support include horizontal support bar, cooperating joint, vertical support rod, are erected The lower end of support bars is connected by the one end of cooperating joint and horizontal support bar, cooperating joint include flip horizontal joint and Vertical overturning joint, flip horizontal joint, vertical overturning joint include the first connector, the second connector and connecting shaft, the A side of a connection piece is hinged by connecting shaft and a side of the second connector, between the first connector and the second connector Equipped with mutually matched limit end face, first connector in flip horizontal joint and second connector in vertical overturning joint are fixed Connection;Lock connecting rod include the first attachment base, the second attachment base, the first locking bar, the second locking bar and V-type closing piece, the first attachment base, Second attachment base is hinged with corresponding vertical support rod respectively, and the outer end of the first locking bar and the first attachment base are hinged, the second locking bar Outer end and the second attachment base it is hinged, the first locking bar, the second locking bar inner end on the downside of be equipped with limit film, the both ends of V-type closing piece It is hinged with the inner end of the inner end of the first locking bar, the second locking bar respectively, and V-type closing piece is in the upper surface of limit film;First connection The first confined planes, the second confined planes and the fillet with the cooperation of vertical support rod, the first limit are equipped on seat, the second attachment base Face, the second confined planes are disposed adjacent, and fillet is between the first confined planes and the second confined planes.
It is set as can be rotated and positioning between the first attachment base, the second attachment base and vertical support rod that will lock connecting rod On the basis of, it sets cooperating joint to include flip horizontal joint and vertical overturning joint, wherein flip horizontal joint and perpendicular Straight overturning joint includes the first connector, the second connector, connecting shaft;In this way, upon deployment, first along vertical overturning joint Horizontal support bar is laid flat downwards by connecting shaft downward horizontal support rod, then rotates two vertical support rods, two are turned over vertically Turn joint and turn to two sides (general 90 ° of rotation), then, as long as by two downward light pressure V-type closing pieces until the two sides of V-type closing piece By the blocking of limit film, the first locking bar, the second locking bar just strut outward, so that two vertical support rods are strutted outward, by In V-type closing piece stress when middle is downwards and by the blocking of limit film, applies active force from two sides, the first lock can not be changed The position of bar, the second locking bar, V-type closing piece, therefore stable state is maintained, then along the connecting shaft downward horizontal in vertical overturning joint Support rod, then, the connecting shaft by horizontal support bar around flip horizontal joint are inwardly overturn, strutting and assisting in locking connecting rod Flip horizontal joint is just realized under the tension of locking mechanism, overturns the self-locking of joint vertically, and entire bracket is made to be in the steady of expansion Determine state;Pack up folded when, as long as gently drawing or patting V-type closing piece upwards, make V-type closing piece be detached from lower end dead point, first Locking bar, the rotation of the second locking bar prop up V-type closing piece and stack together, to make two vertical support rods stack together, then Rotate backward two vertical support rods, make to overturn joint vertically and turn to intermediate (general 90 ° of rotation), at the same by horizontal support bar around The connecting shaft in flip horizontal joint flips outward, and makes horizontal support bar, overturns joint, the alignment of vertical support rod vertically, it will be able to Horizontal support bar is folded with vertical support rod along vertical overturning joint, is not necessarily to carry out in expansion, folding in this way Manual locking and unlock, one can be carried out operating, and is unfolded, folds simpler convenience, carries convenient for single, is more suitable for open country Outer operation is particularly suitable for field medical first aid and uses.
As a preferred embodiment of the present invention, the multiple auxiliary locking mechanism scattering device is in described two horizontal branch Between strut, between two vertical support rods, between two support arms.
As the further preferred embodiment of the utility model, the auxiliary locking mechanism includes made of soft material One sleeve, second sleeve and connecting band, connecting band are connected between first sleeve and second sleeve.First sleeve, second sleeve For being socketed in corresponding horizontal support bar, vertical support rod, support arm, and connecting band plays tension.It is above-mentioned soft Material generally uses the preferable material of the toughness such as canvas, non-woven fabrics, naturally it is also possible to use flexible plastic.
