Abstract
The utility model relates to a stepless positioning window catch which belongs to the improvement of the catch device of a door and a window, suitable for being used for various doors and windows. The utility model comprises a supporting rod (3) which is arranged between two fixing plates and a piston linkage mechanism which is composed of a piston (10). A one-way valve (7) is in series connection with a piston cylinder (6) and a liquid containing cylinder (8). One end of the valve gate of the one-way valve (7) is connected with a starting button (9). Pressure which is from wind speed for a door and a window acts on the piston (10) by the supporting rod (3). When the pressure from the outer of the piston is bigger than the pressure in the inner of the piston cylinder, the piston linkage mechanism moves inwards and simultaneously drives the door and the window to slowly close and self-lock. The utility model can achieve the aim of stepless positioning, and has the functions of safety and anti-theft.
Description
The utility model relates to the improvement invention that door and window wind colludes device.
The existing door and window wind that uses colludes, and generally adopts circle to collude or cooperates the location with fixed cone on being installed in door window frame boring several fixing holes on the handle for doors and windows, has only limited several grades so after all, and need artificial control just can finish.
In view of the deficiencies in the prior art, the purpose of this utility model aims to provide a kind ofly to be had stepless positioning function and can collude by the wind of self-closing doors window when wind is big.
Task of the present utility model is finished as follows: the utility model comprises fixed head (1), (4), fixing hole (2), support bar (3), sealing ring (5), piston rod (6), one way valve (7), liquid container (8), start button (9), piston (10), the support bar (3) that is located between two fixed heads is formed piston crank mechanism with piston (10), be provided with one way valve (7) between piston rod (6) and liquid container (8), valve one end of described one way valve (7) connects start button (9).
The utility model compared with prior art, have stepless location characteristics and can be when wind be big the self-closing doors window, it is simple in structure, imagination rationally, cost is low, and antitheft effectively, not only safety but also reliable.
The utility model has following accompanying drawing
Fig. 1 is a structural representation of the present utility model
Accompanying drawing has been represented design feature of the present utility model, in conjunction with the embodiments the utility model is described in further detail below again.The utility model comprises fixed head (1), (4), fixing hole (2), support bar (3), sealing ring (5), piston rod (6), one way valve (7), liquid container (8), start button (9), piston (10), the support bar (3) that is located between two fixed heads is formed piston crank mechanism with piston (10), connect with hinge between two fixed heads, and have a fixing hole (2), one way valve (7) in parallel between piston rod (6) and liquid container (8), valve one end of one way valve (7) is connecting the start button (9) that is located at liquid container (8) outside, available any liquid in the piston rod.The utility model adopts piston crank mechanism and unidirectional hydraulic means to reach the purpose of stepless location and self-closing doors window and self-locking, that is to say that people can be according to hobby or the health size of freely selecting window to open or close of self, and can freely select self-closing doors window when which kind of degree wind speed arrive greatly by the valve pressure of regulating one way valve, piston rod of the present utility model can be fit within the door window frame, take up room with minimizing, start button (9) is installed in house interior, open start button in the time that door and window need being opened earlier, push the door and window size then according to demand open, decontroling start button can locate by locking, plays certain antitheft effect.Use the utility model, both arbitrarily convenient, safe and reliable again, and can be when wind be big the self-closing doors window, in order to avoid impaired, be that a kind of extremely desirable door and window wind colludes.
Claims (3)
1, a kind of stepless location wind colludes, form by fixed head (1), (4), fixing hole (2), support bar (3), sealing ring (5), piston rod (6), one way valve (7), liquid container (8), start button (9), piston (10), the support bar (3) that it is characterized in that being located between two fixed heads is formed piston crank mechanism with piston (10), be provided with one way valve (7) between piston rod (6) and liquid container (8), valve one end of described one way valve (7) connects start button (9).
2, stepless location as claimed in claim 1 wind colludes, and it is characterized in that between two fixed heads (1), (4) being that hinge connects.
