A kind of plastic-steel door/window press strip having triple seal function
The utility model belongs to plastic-steel door and window field, and in particular to a kind of plastic-steel door/window press strip.
The glazing bead of European plastic-steel door and window, the hook pawl and its hook pawl pedestal and sash using press strip commonplace at present
The cooperation of press strip slot, not only secured the effect that press strip realizes pressed glass, and but also played sealing function, make outdoor air can not be along window
The osculum of fan pours in down a chimney into interior.But the hook pawl and pedestal of press strip and the press strip slot outer of sash, in extrusion process very
Ideal straightened condition is fully achieved in difficulty, and local is slightly not straight, can make when the cooperation of press strip and sash to be stiff dough and stiff dough
It contacts and generates partial aperture, Utopian complete fitting cannot be reached.Therefore after reality is installed at window, outdoor wind-force compared with
When big, extraneous air is more or less to be poured in down a chimney along the osculum of sash into interior, therefore is stood by the window feeling in autumn and winter people
There is cool breeze to press strip position.
The utility model provides a kind of plastic-steel door/window press strip having triple seal function, for the press strip with sash
Slot coordinates pressed glass, which includes press strip ontology, and the press strip ontology, which is equipped with, hooks pawl pedestal, hooks pawl；It is characterized in that：Institute
Press strip ontology is stated to extend outwardly equipped with elastic piece.
Preferably, the angle of the elastic piece and press strip ontology is 60~80o.
Preferably, the elastic piece is coextruded with press strip ontology in production.
Preferably, the elastic piece is rubber and plastic elastic piece.
Preferably, elasticity the length of a film 3mm -5mm, thickness 1mm -2mm.
Compared with prior art, the utility model has the advantages that：
The utility model provides a kind of plastic-steel door/window press strip of the elastic piece with rubber-plastic elastomer, which exists
After press strip assembles pressed glass, it can be close to cover on the inside of sash press strip slot, sealing function is effectively played, prevents outdoor air from falling
It pours into interior, outdoor air or strong wind from the osculum of sash to pour in down a chimney into indoor phenomenon, improves the practical heat preservation of plastic-steel door and window
Description of the drawings
Fig. 1 is a kind of structural representation for the plastic-steel door/window press strip having triple seal function provided by the utility model
Fig. 2 is sealing effect after the cooperation of the plastic-steel door/window press strip sash provided by the utility model with elastic piece
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings
As shown in Figure 1, the plastic-steel door/window press strip provided by the utility model for having triple seal function, it is used for and window
The press strip slot 7 of fan coordinates pressed glass, which includes press strip ontology, and the press strip ontology, which is equipped with, hooks pawl pedestal 1, hooks pawl 2；Institute
Press strip ontology is stated to extend outwardly equipped with elastic piece（3）.As shown in Figure 1, the angle 60-80 of the elastic piece and press strip ontology is spent；It is long
3mm -5mm, thickness 1mm -2mm, the elastic piece are coextruded with press strip base material in production（Preceding co-extrusion or rear co-extrusion）.The bullet
Property piece be rubber and plastic elastic piece.
As shown in Fig. 2, after being assembled at window, press strip pressed glass, the 2 wedge pressure bar groove 7 of hook pawl realizes that first layer is close
Seal function；Described to hook outer cooperation realization second layer sealing of the pawl pedestal with press strip slot, the elastic piece 3 can be close to cover sash
Protrusion on the inside of press strip slot realizes third layer sealing function, as triple seal function, prevents outdoor air from pouring in down a chimney and enter the room
It is interior；To effectively play sealing function.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in also be the utility model one of embodiment, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
