Abstract

The utility model discloses a window opening and closing device, it is by deciding roof beam 1, control balladeur train 2 and 3, knee lever 4, crank arm 5, spout 6 and stay cord 7 are constituteed, control balladeur train 2 and 3 movable sleeve on deciding roof beam 1, stay cord 7 one end links to each other with the pull ring 10 that hinders of left balladeur train 2, the other end links to each other with the pull ring 11 that hinders of right balladeur train, control two 4 one ends of knee lever and fix respectively on controlling balladeur train 2 and 3, the other end respectively with control two 5 one end swing joints of crank wall, control two 5 other ends of crank arm again with control balladeur train 6 swing joint, the pull ring 12 that hinders of left balladeur train 2 is walked around fixed pulley 9 through another stay cord 8 and is linked to each other with the pull ring 13 that hinders of right balladeur train 3, therefore the.

Description

Opening or closing means for windows and doors

The utility model belongs to a kind of door and window headstock gear.

Existing open-type door and window close that Shi Junyong pulls and down latch or lock close, open Shi Yaoyong and draw back pin or unblank, firmly push open again and just can open the door or window, thereby use and go up trouble.

The utility model provides a kind of stay-supported machinery to open and close the device of window.

The purpose of this utility model is to realize like this, by deciding beam 1, left and right sides balladeur train 2 and 3, curved bar 4, crank arm 5, the window headstock gear that chute 6 and stay cord 7 are formed, left and right sides balladeur train 2 and 3 is actively set on to be decided on the beam 1, one end of stay cord 7 links to each other with the resistance draw ring 10 of left balladeur train 2, the other end links to each other with the resistance draw ring 11 of right balladeur train 3, about two curved bar 4 one ends be separately fixed on left balladeur train 2 and the right balladeur train 3, the other end respectively with about two 5 one ends of cranking arm flexibly connect, about two crank arm 5 other ends respectively with about two chutes 6 flexibly connect, the resistance draw ring 12 of left balladeur train 2 is walked around fixed pulley 9 by another root stay cord 8 and is linked to each other with the resistance draw ring 13 of right balladeur train 3.

The utility model has been owing to adopted the stay-supported mechanical closure mechanism, thereby compared with prior art, very convenient in the use, but as long as once stay cord switch window.

Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.

As Fig. 1, Fig. 2 and shown in Figure 3, by deciding beam 1, left and right sides balladeur train 2 and 3, curved bar 4, crank arm 5, the window headstock gear that chute 6 and stay cord 7 are formed, left and right sides balladeur train 2 and 3 is actively set on to be decided on the beam 1, by as shown in Figure 4, stay cord 7 one ends pass and are fixed on holder 22 and link to each other with the resistance draw ring 10 of left balladeur train 2 with 23 brake pipe 21, the other end is connected on the resistance draw ring 11 of right balladeur train 3, when stay cord 7 one ends pull down, then pulling force is turned right resistance draw ring 10 and is drawn, when moving resistance draw ring 10 to when running into the pin 18 of balladeur train seat 17, three pulleys 14 that drive on the left balladeur train 2 are being decided on the beam 1 to left movement, because resistance draw ring 12 links to each other with pin 19 on the left balladeur train 2 by spring 16 and resistance draw ring 10 links to each other with pin 18 by spring 15, thereby resistance draw ring 12 is walked around the resistance draw ring 13 of fixed pulley 9 pulling right pulley 3 by another root stay cord 8, when resistance draw ring 13 is moved pin 24 on the right balladeur train 3 to, driving right balladeur train 3 moves right, because resistance draw ring 11 links to each other with pin 26 on the right balladeur train 3 by spring 25, thereby resistance draw ring 11 also moves right, and stay cord 7 other ends link to each other with resistance draw ring 11, thereby stay cord 7 other ends just move upward; On the other hand, by as Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, because curved bar 4 fixed connections on this headstock gear left side are on left balladeur train 2,5 link joints and crank arm in the left side of left curved bar 4 other ends and this headstock gear, 5 other ends of cranking arm pass between pin 27 and the pulley 20 and can slide around pulley 20, again with chute 6 link joints, when left balladeur train 2 when deciding beam 1 to left movement, drive curved bar 4 to left movement, and curved bar 4 drives crank arm 5 around pulley 20 slips, 5 on chute 6, move down thereby making cranks arm,, thereby just window is opened because chute 6 nails are on window frame or doorframe; When should stay cord 7 other ends pulling down, window is just closed.The structural principle of right balladeur train 3 is with left balladeur train 2, and just the direction of motion is opposite.When stay cord 7 one ends pulled down, right balladeur train 3 moved right, and its window that links to each other is also opened simultaneously; When stay cord 7 other ends pulled down, the window that right balladeur train 3 links to each other was also closed simultaneously with left balladeur train 2 is the same.Thereby the utility model opens or closes two fan windows easily simultaneously.
