Abstract
The utility model relates to a large awning for outdoor business booths and amusement places. A folding supporting arm is provided with an adjusting joint and a screw bolt joint for adjusting the angle of the awning. A spring on a hook in a supporting arm pipe is tensioned by the action of a steel cable. The connecting point between a front supporting arm and a rear supporting arm forms a space angle under the action of the shape of a part and tight fixing screws. When awning cloth is extended, the spring can extend the folding supporting arm under the action of the steel cable. When a roller winds and contracts the awning cloth, supporting arms can be contracted along the space angle until the supporting arms are parallel and are contracted. A contracting and spreading mechanism can be controlled automatically or by hands. The utility model has the advantages of high rigidity, flat contraction and winding, and convenient operation.
Description
The utility model is a kind of open-air commercial stand or the employed folding arm formula of playground reel sunshade.
Can support in order to reach, purpose that again can the folding and unfolding sunshade, the folding structure of the sunshade of Shi Yonging has in the market:
Framework type: support arm is four connecting rod hinge mechanisms, because rigidity is not enough, paulin stretches and can not tighten, and support arm structure is too fat to move, can only lean on artificial push-and-pull, folding and unfolding, and sunshade can not be adjusted angle.
Collapsible: the sunshade area is little, uses restrictedly, only is suitable for sunshade on the window.
The sunshade support arm rigidity of above structure is not enough, and the sunshade area is little, is difficult to extended flat, and rolling is too fat to move messy, the needs that the incompatibility modern city is traveled, gone sightseeing, beautifies.
Task of the present utility model is the large-scale sunshade that will design after a kind of improve.Sunshade support arm rigidity is strong and folding and unfolding is collapsible, compact conformation, during the reel rolling under the effect of folding arm the paulin rolling neat, stretch tight smooth, but the also manual operation of folding and unfolding operable automatically, the sunshade area is big and can adjust positive fluffy angle.Outward appearance can do to beautify interspersing of city.
Task of the present utility model is finished as follows:
One side that square type paulin is long is fixed on the thin pole, is installed in the little pipe in the reel, and the paulin another side uses the same method and is loaded in the little cylinder of overhanging tube.The folding and unfolding of paulin and support vary in size according to area two to three folding arms can be installed.
Folding arm is made up of front arm and back arm.Mainly be equipped with in the pipe of back arm and regulate joint, screwed joint, root axle, three-jaw joint, hook, spring, single hook, cable wire, ears joint; Monaural joint, tip joint mainly are housed in the pipe of front arm.
Earlier adjusting and bolt two joints that have arc groove on the back arm are connected together with bolt, in the screw hole of adjusting joint a check screw is installed.The other end of screwed joint links to each other with the three-jaw joint with the root axle.Inlay card one hook can be hung two to three springs according to circumstances on the three-jaw joint on the hook, and the spring other end hangs with the single hook of a T-shaped, hangs with a cable wire on the lifting-hook of single hook.Ears joint on the back arm pipe and the monaural joint on the front arm pipe are connected as a single entity with axis, and this tie point is the tie point of front and rear support arm, and front and rear support arm forms a space angle under part profile and check screw effect.Have under the cable wire clamp, when cable wire by the ears joint, be stuck in following time of notch of monaural joint lower end along the groove on the monaural joint, spring begins stressed, at last the tip joint is fixed on the termination of front arm pipe.
Mounted folding arm, the tip joint on the front arm are installed on the overhanging tube guide rail of sunshade, and the adjusting joint of back arm is fixed on the square steel.Bolt in screwed joint and adjusting joint arc groove can slide along groove.Control displacement with this size that changes paulin inclination sunshade angle with check screw.
Reel folding and unfolding power source has automatically and manual two kinds.What adopt automatically is that deceleration self-locking micromachine or motor-driven worm and gear drive the reel rotation.Can also the automatic remote control operation if in the circuit operation system, add the remote control receiving lines.
What manually adopt is that manual worm gear worm drive reel rotates.
When reel under motor or worm and gear backward rotation drive, folding arm is the smooth stretching, extension of paulin under the effect of spring shrinkage tensions, when folding arm was stretched over maximum angle, paulin was Breadth Maximum at this moment.
When reel under motor or worm and gear forward rotation drive, paulin is toward the reel rolling, under the paulin tension, folding arm reclaims along space angle around axis and the rotation of root axle, the interior spring of support arm this moment draws back at the effect lower stress of cable wire, paulin is when the zero-bit, and front and rear support arm is folding to be drawn close and parallel with overhanging tube with reel, finishes rolling.
Characteristics of the present utility model:
One, folding arm rigidity is strong.In rolling and the stretching process, support arm is under spring and cable wire effect, and paulin is in smooth tight state all the time, and compact overall structure is taken down the exhibits efficiently.
Two, retractable operation variation.Can manual, electronic or remote control.
Three, this structure can be used for large-scale sunshade.
