Abstract
The utility model discloses an adjustable automatic position window support, comprising fixing plates 1, short connecting rods 2, long connecting rods 3, fixing folded plates 4, etc. The fixing plates 1 and the short connecting rods 2 are connected by countersunk head rivets, and the fixing flaps 4 and the long connecting rods 3 are connected by the countersunk head rivets which are worked as the axis of revolution. The connecting shaft of the long connecting rods 3 and the short connecting rods 2 are provided with a section of thread, and section of the thread is matched with mitre nuts to control the rotation of the long connecting rods 3. The adjustable automatic position window support can make the window automatically positioned not only in the fully opening position but also other opening positions. The utility model has the advantages of simple structure, low cost and convenient operation.
Description
The utility model relates to a kind of adjustable automatic location window fastener that is used on the window.
The window fastener that uses has fixed and adjustable two kinds now.Fixed window fastener can only be fixed on sash on the position, also must hang up hook and just can make the sash location after opening sash.Though adjustable window fastener can be positioned different enable possitions to sash, but because this window fastener has an end to protrude by window frame usually, and the more little protrusion more of opening angle, so neither attractive in appearance, limited its scope of application again, after sash is opened into desired location, also must lock lock nut or screw and just can make the sash location, in addition, because its complex structure, cost is also high.
In order to overcome existing window fastener inconvenience in the use, the utility model proposes a kind of novel window fastener that can be automatically positioned on maximum open position.This window fastener also has the adjustable characteristic of opening angle.
Accompanying drawing 1 is the utility model window fastener structural representation.1 is fixed flat planar among the figure, is used for an end of window fastener is fixed on the window frame.2 is short connecting rod, and 3 is long connecting rod, and short connecting rod 2 and long connecting rod 3 work to support sash jointly.4 are fixing flap, are used for the other end of window fastener is fixed on the sash.5,6 be sunk head rivet, sunk head rivet 5 lower ends and fixed flat planar 1 close-coupled together, and make short connecting rod 2 can with sunk head rivet 5 serve as the axle freely rotate.Sunk head rivet 6 lower ends and long connecting rod 3 close-coupled together, and to make fixedly flap 4 can serve as that axle freely rotates with sunk head rivet 6.7 is coupling spindle, this lower end and short connecting rod 2 close-coupled together, there is one section screw thread the upper end, and is furnished with dish shape nut 8, unscrews dish shape nut 8 long connecting rod 3 is freely rotated around axle 7, tightens the rotation that dish shape nut 8 can limit long connecting rod 3 again.Above-mentioned window fastener can destroy the end thread of coupling spindle 7 after assembling, and dish shape nut 8 both can't be screwed down, and does not influence long connecting rod 3 again and rotates around axle 7, has so just prevented that dish shape nut 8 from losing because of stubborn De Taisong.
Introduce the automatic positioning principle of the utility model window fastener below.After the utility model window fastener is loaded onto window (referring to accompanying drawing 3), the utility model window fastener, sash and window frame have been formed a four-bar linkage as shown in Figure 2.01 represents window frame and fixed flat planar among the figure, and establishing its length is L1, and 02 represents short connecting rod, and establishing its length is L2, and 03 represents long connecting rod, and establishing its length is L3, and 04 represents sash and fixing flap, and establishing its length is L4.When satisfying condition
L2+L3＜L1+L4 and L3+L4＜L1+L2
The time, this four-bar linkage just becomes a double rocker mechanism, and 01 to be frame, 02 is a rocking bar, and 03 is connecting rod, and 04 is another rocking bar.When with rocking bar 04 for former when shaking bar, position shown in the figure is exactly the dead-centre position of this mechanism.This moment, so the former bar 04 that shakes is passed to the centre of gyration of the power of driven rocking bar 02 by driven rocking bar by connecting rod 03, this power did not produce moment to driven rocking bar, and driven rocking bar is rotated owing to connecting rod 03 and driven rocking bar 02 conllinear.After we were pushed into this position to sash, if we do not give moment of short connecting rod, sash just can not leave this dead-centre position because of its suffered power (as owing to wind) in other words.In addition because the quality of sash is more much bigger than the quality of short connecting rod, so, when we during to the extrapolation sash, it is what to be difficult to by this dead-centre position, the automatic location of sash when this has just realized windowing.
Accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5 are the utility model window fastener mode of occupation schematic diagram.1 is fixed flat planar among the figure, and 2 is short connecting rod, and 3 is long connecting rod, and 4 are fixing flap, and 5,6 are sunk head rivet, and 7 be coupling spindle, and 8 is dish shape nut, and 9 is sash, and 10 is window frame, and 11 is the hinges of connection sash and window frame, and 12 is wood screw.Situation when accompanying drawing 3 is standard-sized sheet.In this situation, only need outwards push sash open and get final product, sash will be automatically positioned on this position.At this moment, need not to tighten dish shape nut, wind can not blow sash.When closing window, hand steered dish shape nut place can shut toward an interior band.Accompanying drawing 4 is that sash is in the not situation of fully open position.In this situation, sash is pushed into tightens dish shape nut after the desired location and get final product.Accompanying drawing 5 is the situations of shutting behind the sash.
The utility model window fastener must be selected a suitable installation site with reference to accompanying drawing 3 and 5 two kinds of situations of accompanying drawing when mounted.
The utility model window fastener is compared with existing window fastener, because it has the function of automatic location, so very easy to use.In addition, it also have simple in structure, with low cost, advantage such as be widely used, be fit to very much general hardware plant produced.
Claims (3)
1, a kind of by fixed flat planar 1, short connecting rod 2, long connecting rod 3 and the fixing automatic location window fastener formed such as flap 4, it is characterized in that this window fastener can with sash and double rocker mechanism of window frame composition, play the support sash jointly by short connecting rod and long connecting rod.
2, automatic location as claimed in claim 1 window fastener is characterized in that fixed flat planar with short connecting rod, fixedly flap all uses sunk head rivet to connect with long connecting rod, and is gyroaxis with this rivet.One section screw thread is arranged on the coupling spindle of long connecting rod and short connecting rod, and be equipped with the rotation that dish shape nut is controlled long connecting rod.
3, as claim 1 and the described automatic location of claim 2 window fastener, it is characterized in that its dish shape nut is non-removable.
