Description

Telescopic elastic force protective window

The utility model is particularly related to a kind of telescopic elastic force protective window.

Existing telescopic elastic force protective window be by left and right side be window frame, the top of the slideway telescopic sash, the fixed pulley that is fixed on the window frame upper-lower position that are fixed on slideway top, be installed in the lock body in the telescopic sash lower frame and be fixed on down gear in the window frame, tooth bar, link to each other with tooth bar and link to each other through the stay cord that fixed pulley links to each other with telescopic sash bottom, and the lockhole corresponding with the lock body upper lock tongue arranged in the bottom of slideway.During use, gear is rotated, drive tooth bar and move, and then make stay cord drive sash along the slideway lifting by crank.Because by the tooth bar transmission, crank shakes a week, the stroke of tooth bar is less.For about 2 meters high window frames, if think complete opening and close telescopic elastic force protective window, crank need rotate more than 40 weeks.Therefore, the telescopic elastic force protective window of this structure operates not only time-consuming but also require great effort, and uses inconvenient; And its complex structure for the windowsill condition with higher, also need perforating could be placed crank on former window frame, therefore, it installs inconvenient, and has destroyed the contour structures of the existing windowsill of user, has influenced attractive in appearance.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of quick for installation, easy and simple to handle and simple in structure, telescopic elastic force protective window of not affecting the appearance after installing is provided.

The utility model is achieved in that it has a left side, the right side is the window frame of slideway, telescopic sash, there is lockhole said slideway lower end, in telescopic sash underframe, lock body is housed, its special character is on a left side, right slideway upper end is fixed with support, between two supports, be fixed with cross bar, on a left side, cross bar middle part, right positions has a left side respectively, right spring abutment, said spring abutment is fixed on the support bar by holding pin, at cross bar left end and right-hand member a reel shape left side is housed respectively, right spring abutment, between two left spring abutments and between two right spring abutments the pulling force torsion spring is being housed respectively, be wound with stay cord on the reel of reel shape spring abutment, an end of stay cord is fixed on the reel, the other end arranges and is fixed on the lower end of telescopic sash along slideway.

Because the unlatching of this telescopic elastic force protective window is to realize by the restoring force of pulling force torsion spring, and is therefore simple and efficient to handle, time saving and energy saving.In addition, it is simple in structure, because crank need not be installed, need not on former window frame in an instant, and is therefore, easy for installation and do not affect the appearance.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the supporting structure schematic diagram;

Fig. 3 is a C-C sectional drawing among Fig. 1;

Fig. 4 is a D portion enlarged drawing among Fig. 1;

Fig. 5 is an E portion enlarged drawing among Fig. 1.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in the figure, the utility model has both sides to be a left side, the window frame of right slideway 1, on the bottom surface of said slideway 1, last installing hole 1B and lockhole 1A are arranged respectively at the bottom, in slideway 1, be placed with telescopic sash 2, and the upper sheet 2B two ends of sash 2 are fixed on slideway 1 top, in the underframe 2A of said sash 2 lock body 3 is housed, and the dead bolt 3A in the lock body 3 is corresponding with lockhole 1A, on a left side, installing hole 1B position is welded with support 5 on the right slideway 1 upper end correspondence, between two supports 5, be fixed with cross bar 10, and cross bar 10 passes support 5 back insertions and goes up in the installing hole 1B, take back at cross bar 10 middle parts, two side positions that take over are respectively installed with a left side, right spring abutment 8, a said left side, right spring abutment 8 is fixed on the cross bar 10 by holding pin 9, at cross bar 10 left ends and right-hand member a reel shape left side is housed respectively, right spring abutment 6, at two left spring abutments and two right spring abutments 6, be separately installed with pulling force torsion spring 7 between 8, on a reel shape left side, be wound with stay cord 4 on the reel of right spring abutment 6, an end of stay cord 4 is fixed on the reel 6, the other end is arranged and is fixed on the assembly bottom of telescopic sash 2 along slideway 1.

When actual installation, the window frame 1 of this telescopic elastic force protective window is fixed on the body of wall between the two-layer window, spur telescopic sash 2 lockhole 1A position to the slideway, locking lock body 3 inserts in the lockhole 1A dead bolt 3A, and at this moment, this protective window is in closed condition; Simultaneously, drive reel 6 by stay cord on the sash 24 and rotate, pulling force torsion spring 7 is produced draw torsional elasticity deformation; After opening lock body 3, under the restoring force effect of pulling force torsion spring 7, make reel 6 counter-rotatings, be wrapped in stay cord 4 on the reel 6 and drive to move on the underframe 2A of telescopic sash 2 and tighten the position, make this telescopic elastic force protective window be in opening.

Claims (1)
