Existing at present " sliding sash with disappearing screen window ", " reel screen window ", because cost height, simultaneously must be by special messenger, specialty by dress, and to transform original window-frame, cost dearly, thus not susceptible to user acceptance, the screen window of some other structures is also arranged, but owing to be to be difficult for after the one-time positioning unloading all, so also very undesirable.

The purpose of this utility model is to provide a kind of easy to loading and unloading, good airproof performance, screen window that cost is low, and it can be supporting with various portable aluminium alloyss and plastic-steel window.

The utility model is achieved in that a kind of seamless flexible screen window, comprise screen window framework and window screening, the fixing shelves of screen window framework one side are gone up device flexible grade parts, flexible shelves parts by be packed in lever in the middle of the fixing shelves rise the formula pulley yoke, be packed in fixing shelves up and down the built-in retracted for clearance spring at two ends and the flexible shelves that are coated on the fixing shelves form, the lever formula turning rolls that rises includes spanner, roller and pin.Spanner is that fulcrum is installed on the fixing shelves with the pin, roller devices is in spanner the inner, offer horizontal concrete chute on the telescopic chute shelves, the telescopic chute shelves rely on the horizontal concrete chute relative fixed on pin, can horizontally slip, built-in retracted for clearance spring one end links to each other with fixing shelves, and the other end links to each other with the telescopic chute shelves.When screen window by after loading onto window-frame, as long as pull lower ejector lever, because the roller that lever principle is installed in turning rolls one end is the center with the pin to be done circular motion the telescopic chute shelves is stretched out to a side spreading of screen window like a cork, make the both sides of screen window be close to the window frame that it faces mutually, simultaneously, because there is certain distance the inboard of pinch bar with the inboard of fixing shelves, and pinch bar becomes 90 ° vertical angle with roller tension axis, therefore, when spanner is pulled down near fixing shelves, roller tension point has been crossed the tension center line, thereby has played self-locking action, has fixed the telescopic chute shelves.When needs unload window screening, only need upwards to pull lightly handle, the roller on lever top still is that a circular motion is done at the center with the pin, releasing is to the tension of telescopic chute shelves, the telescopic chute shelves make it shrink to fixing shelves under the effect of two ends back-moving spring and are adjacent to, thereby make the screen window both sides produce the gap with facing mutually between the window window-frame, can unload screen window from window-frame like a cork.

Compare with existing screen window, telescopic section of the present utility model adopts the structure of lever principle tension location and the automatic retracted for clearance of built-in spring, when setting because thereby flexible progradation guarantees that whole window does not have the slit, the shelves that will stretch when built-in spring works when unloading shrink automatically, make and produce appropriate gap between the sash, therefore can easily screen window be taken off from window-frame, all operations is all by two pinch bar controls up and down, simple to operation, what have more implementation value is to reequip on the original user screen window, cheap, original object utilizes fully, can not produce discarded object so that impact effect because of using new product.
