Description

Unidirectional roller bearing position limited folding formula Pneumatic curtain support
Technical field
The present invention relates to the technical field of curtain, specifically a kind of Pneumatic curtain supporting structure.
Background technology
At present, comparatively conventional Window curtain structure arranges chute at the upper limb of window, some hooks are sliding combined with in described chute, clasp in curtain body sequentially buckles on each self-corresponding hook, thus by grasping curtain body, and swing the folding that curtain body realizes curtain, but the power that above-mentioned people's grasped curtain applies not only has the power for folding curtain of horizontal direction, and have the power pullling curtain down, therefore personnel are needed to apply larger active force, this inconvenience of causing not only to folding curtain, and after the excessive or permanent use of power of pullling, the clasp of curtain upper end and hook also can be caused to damage.
Although and also have in prior art part by driven by motor drag-line, the final automation curtain directly driving hook to slide, but the process of above-mentioned driven by motor drag-line, not only there is the risk of Cable failure or link disengagement, and drag-line stretches and storage process all needs drag-line passage and accommodating mechanism, this all further adds structural complexity, adds installation cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of reliable and stable and unidirectional roller bearing position limited folding formula Pneumatic curtain support that structure is simple, installation cost is low.
The technical solution used in the present invention is: provide a kind of unidirectional roller bearing position limited folding formula Pneumatic curtain support, it comprises grooved rail, be slidably fitted on grooved rail for hanging the hook of curtain, and the driving mechanism for driving hook to slide along grooved rail length direction, described grooved rail is hollow structure, described driving mechanism comprises the air pump possessing inflation and air suction function and the some travel(l)ing rests be located in grooved rail, the madial wall of travel(l)ing rest and grooved rail is slidably matched, an elastic bellows is equipped with between any two adjacent travel(l)ing rests, and air supply channel travel(l)ing rest between any two adjacent elastic bellows is equipped with for being communicated with adjacent two elastic bellows, whole elastic bellows is fixed with air supply channel and is communicated with the flexible air cavity forming one end and close, the other end of described flexible air cavity is connected with air pump, the upper end of described hook is connected with the lower end of travel(l)ing rest, the lower end of hook extends to outside grooved rail, position corresponding with hook on described grooved rail is provided with for linking up with the chute slided along grooved rail length direction.
After adopting above structure, unidirectional roller bearing position limited folding formula Pneumatic curtain support of the present invention compared with prior art has the following advantages: first, promote travel(l)ing rest by air pump to slide in grooved rail, thus drive the hook be arranged on travel(l)ing rest to slide, realize the automatic open-close of curtain, thus avoid because rope pulls the problem of fracture and the disconnection brought, secondly enclosed groove track, dust etc. is avoided to be deposited in movable part, cause the problems such as the increase of movable part skin-friction force and damage, play good dust-proof effect, finally, decrease flexible gathering in, the mechanism such as transmission and guiding, only need by air pump bleed or aeration can complete slidably reciprocating of travel(l)ing rest, therefore features simple structure, low processing cost, install and also facilitate.In addition, when family is used, be also convenient to the dust sweeping cleaning grooved rail surface, and can not owing to settling accounts the water stain corrosion causing grooved rail working surface of process.
Improve as one, each travel(l)ing rest in described grooved rail is equipped with some rollers, and the lateral wall of described roller and the madial wall of grooved rail are fitted, and roller on arbitrary travel(l)ing rest is uniformly distributed along the axis circumference of grooved rail madial wall cross section.By the frictional force arranging can take in sail support and grooved rail inwall of roller, travel(l)ing rest is slidably reciprocated more flexible, circumferential equally distributed roller also makes the better load-bearing of travel(l)ing rest simultaneously.
Further, described grooved rail is square grooved rail, described travel(l)ing rest to be joined end to end the square set formed by two cross bars and two montants, and the cross tube of travel(l)ing rest has been rotatably assorted a top rollers, and the sheer pole of travel(l)ing rest has been rotatably assorted bottom roller.Under the Action of Gravity Field of curtain, frictional force between the lower surface of the lower end of travel(l)ing rest and the inwall of grooved rail is maximum, therefore, the frictional force that bottom roller can the most effectively take in sail between support and grooved rail is set, coordinate symmetrically arranged top rollers simultaneously, slidably reciprocating of travel(l)ing rest can well be realized.
Further, two montants of described travel(l)ing rest are respectively equipped with identical left wheel and right roller.Because curtain is under the interference of the foeign elements such as wind-force, it is not be all vertically suspended state, therefore the impacts such as strong wind weather are considered, arrange under left wheel and right roller can make travel(l)ing rest be subject to lateral force situation and also well control frictional force by roller with the side of grooved rail inwall, realize being free to slide of travel(l)ing rest, prevent the draw-in groove phenomenon because side force causes.
Improve as another kind, be provided with the adjustable plate for changing ventilation size in described air supply channel, described adjustable plate is provided with the pore being no less than, and the lateral wall of adjustable plate and the madial wall of air supply channel are fixed and sealed.When air supply channel is directly communicated with the elastic bellows of left and right, first move in one end often farthest away from air pump, drive successively subsequently, the resistance that whole frictional force produces just all is accumulated on outermost travel(l)ing rest by this, therefore easily produces and first weares and teares away from the travel(l)ing rest of air pump part and elastic bellows.And by arranging adjustable plate, make the active force produced during airflow be distributed on each adjustable plate uniformly, thus by controlling the pore opening on each adjustable plate, the adjustable plate reasonable stress realizing diverse location controls.Thus realize the object that whole travel(l)ing rests synchronously draws in.And also substantially increase the service life of each parts.
Further, be provided with some elastic valve in pore, one end of elastic valve and the madial wall of pore are fixed, and the other end of elastic valve extends towards the center of pore, and whole elastic valve is uniformly distributed along the circumference of pore axis.The size that can be realized the pore when the air pressure of air pump is excessive by elastic valve is regulated automatically, the object that the ventilation realizing adjustable plate thus regulates automatically.
As preferably, described elastic bellows is that PVC material is made.
Preferred as another kind, one end away from air pump of flexible air cavity is provided with a protection pore, and the aperture of described protection pore is less than or equal to protection pore place and stretches 1/10 of air cavity cross-sectional diameter.The hypertonia in flexible air cavity can be prevented by protection pore and cause air pump to damage.
As last a kind of improvement, the upper end of described hook forms a collar, the internal diameter of the described collar equals the diameter of the sheer pole of travel(l)ing rest, and the cover of described hook is located on the sheer pole of travel(l)ing rest, and the lower end part be positioned at outside grooved rail of hook forms a suspension part.
