Description
Technical field
The invention belongs to daily living article technical field, relate to screen window, especially relate to a kind of Wind-resistance gauze window.
Background technology
The Main Function of screen window is " mosquito-insect-proof ", and along with improving constantly of people's living standard, increasing screen window occurs commercially; Existing screen window generally comprises the sliding sash of aluminum alloy frame, and window frame is provided with guide rail, and sliding sash is at slide on rails, and this screen window at least exists following shortcoming: 1, push-and-pull easily produces noise; 2, push-and-pull inconvenience etc.Another kind of screen window is rolling curtain, and window cover is provided with reel, when without curtain time, can pack up, easy to operate.But the window screen cloth of this structure rises and declines is all controlled by annular slide fastener, and operating process is loaded down with trivial details, and the application life of screen window curtain is shorter; In order to solve these technical problems existing, people devise and a kind ofly on window cover, are provided with spool and in spool, are provided with the screen window curtain of spring, yarn cord when without screen window curtain, can be packed up by spring by this structure, eliminates the process of loaded down with trivial details push-and-pull process or draw ring shape slide fastener; But this structure is packed up in process at yarn cord, due to the screen resilience effect of spring, the lower beam of yarn cord can go up to window cover end fast, because elastic force is very large, the impact of lower pole pair window cover is very large, and window cover is easily destroyed, and easily produce noise, also there is potential safety hazard in addition.Secondly, the yarn cord of this structure is just fixed in the lower end of yarn cord and upper end, and at its side without any wind force proofing design, such screen window curtain is easily blown off by strong wind and falls, and wind loading rating is poor.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose various solution.Such as, Chinese patent literature discloses a kind of gauze damping reducing gear [application number: 200420072703.7] of automatic window screen, and comprise damping unit and freewheel clutch, one end of damping unit is coaxially connected with one end of freewheel clutch.In addition, Chinese patent literature discloses a kind of pressurization wind resistant device of window screen [application number: 200820187549.6], comprise U-shaped guide rail, gauze, the Sash fastener be connected with gauze is provided with in U-shaped guide rail, the side of U-shaped guide rail is provided with plastic-steel wind resistance bar, one end and the U-shaped guide rail of plastic-steel wind resistance bar are hinged, the position that the opposite side of U-shaped guide rail is corresponding with plastic-steel wind resistance bar is provided with I shape wind resistance bar, and the edge of gauze is connected with Sash fastener through the gap plastic-steel wind resistance bar with I shape wind resistance bar.
Two above-mentioned schemes improve prior art to a certain extent, but two schemes have respective shortcoming, pressurization wind resistant device of window screen is when wind resistance, because yarn cord is stuck, yarn cord can not move, in the course of time easily make yarn cord damage, and the screen window wind loading rating of the program is also poor; The gauze damping reducing gear of automatic window screen is when controlling yarn cord and rising, and controlled the rise speed of yarn cord by damping shaft, this structure has certain cushioning effect, but buffering effect is undesirable, does not thoroughly solve prior art Problems existing.
