Description

The sash switching mechanism

The utility model relates to a kind of sash switching mechanism.

In the prior art, the sash mechanism for opening/closing has three kinds.First kind is the plane hinge type, and this structure makes the cleaning must be to outdoor, for the window cleaning of high residential building, repair and can't realize; Second kind is angle type hinge type, this structure sash is opened 60 millimeters the slit of having an appointment between back and the window frame, and the outer most edge of openable windows is to about 700 millimeters of distance between the operator, and 500～600 millimeters of common people's brachiums, thick 80～100 millimeters of arm, do the window health limited, repair also difficulty; The third be in the middle of revolving structure, though can overcome above-mentioned shortcoming, sealing is poor, occupy the interior space, only is suitable for the high-order window in workshop, auditorium, family room does not adopt this structure.

The purpose of this utility model is to overcome the sash switching mechanism that provides a kind of sash to do 180 ° of upsets outside the deficiencies in the prior art.

The purpose of this utility model is reached by following measure: the sash switching mechanism is affixed by hinge fixed fan and window frame.The axle sleeve form is made at hinge lengthening fan two ends, connects with hinge fixed fan and intermediate support respectively.Support arm one end is connected with the sash support by bearing pin, and the other end constitutes on the frame of window frame with the wing bolt spinning.One circular hole is arranged at intermediate support top, and intermediate support is fixed in place in the middle of the sash back side.

The utility model compared with prior art has following advantage:

1. the utility model sash switching mechanism can make 180 ° of sash upsets, and the people does not go out the family, and arm is not outer to be visited, for cleaning, the repairerment work of window are provided convenience.

2. because an end of sash switching mechanism is positioned at middle part, the sash back side, open and close, increased the support stiffness when sash is opened by the support arm effect.

3. it is controlled that sash opens and closes degree, do not account for the interior space, do not enlarge the inswept area of sash.

4. do not enlarge main size and the volume partly of existing window, low cost of manufacture.

The utility model is as shown in the figure:

Fig. 1 is sash structural representation when closing

Structural representation when Fig. 2 is the sash unlatching

Fig. 3 is the front view of hinge lengthening fan

Fig. 4 is the lateral view of hinge fixed fan

Fig. 5 is the front view of hinge fixed fan

Fig. 6 is the front view of intermediate support

Fig. 7 is a sash support front view

Fig. 8 is the sash bracket front view

The utility model will be described in further detail in conjunction with the embodiments: this sash switching mechanism as shown in Figure 1, hinge fixed fan 3 is affixed with window frame 4.The axle sleeve form is made at hinge lengthening fan 1 two ends, connects with hinge fixed fan and intermediate support 10 respectively.Support arm 6 one ends are connected with sash support 5 by bearing pin 2, and the other end constitutes on sash bracket 8 with wing bolt 7 spinnings, and a circular hole is arranged at intermediate support top, wears bearing pin in the hole, and intermediate support is fixed in the middle place, the back side of sash 9.

When opening sash, sash rotates around the intermediate support bearing pin, and the lengthening fan that drives the lengthening hinge simultaneously is around the rotation of fixed fan bearing pin, and the sash opening degree is by the pivot angle size decision of support arm.Screw just fixed sash position of wing bolt, during Turn window sash, only need screw off wing bolt and get final product.
