Abstract
The utility model provides a combined middle sealing strip used on an energy-saving casement window or door, which solves the technical problem that the rubber price rises increasingly at present, thus the price of the middle sealing strip on the energy-saving casement window rises too. The key point of the utility model is that the middle sealing strip is formed by combining the head of soft PVCor rubber material and the base of plastic sectional material with the strip inserting or co-extrusion technology. The utility model has the beneficial effects that the head is made of the soft PVC orrubber, which meets the quick reinstatement requirement of the sealing strip, the base is made of the cheap plastic sectional material and the bulk thereof accounts for more than 80 percent of the bulk of the whole sealing strip, consequently, the cost of the whole sealing strip is reduced greatly.
Description
Technical field
The utility model relates to a kind of weather strip that uses on energy-saving casement window or door, be arranged on the intermediate seal bar that seals frame and fan on window frame or the doorframe specifically.
Background technology
Energy-saving casement window comprises that heat-insulating bridge-cut-off window, plastic-aluminum aluminium composite window and aluminum plastic compound window etc. have significant sealing, heat insulating ability, it is provided with inboard, the outside and middle three rubber weather strips that are used to seal frame and fan on window frame, inboard identical and very little with outside weather strip volume, intermediate seal bar volume maximum is more than four times of inboard or outside weather strip.In rubber price high day by day today,, significant if can lower the price of intermediate seal bar.Immutable because of intermediate seal strip and volume, reduce its price and can only reduce in the price of rubber the Ji, but this is again unpractical, neither the technical problems to be solved in the utility model.
Summary of the invention
For solving the problem that existing intermediate seal bar holds at high price, the purpose of this utility model is to provide a kind of combined type intermediate seal bar, and it is cheap.
Why the intermediate seal bar adopts rubber to make is the elasticity that will utilize it, sash or door leaf continually during Push And Release the head of intermediate seal bar rapidly reinstatement cooperates with the heat insulating strip of sash or door leaf, realization seals.Therefore its part except that head is not need rubber-like, is to make with the lower material of other price.The utility model is to wear bar or coextrusion process constitutes by the base of head of flexible PVC or rubber material (also being seal head) and plastic material.Its mounting means and invariant position, its head cooperates with the heat insulating strip of sash, realizes sealing.
Compared with prior art, the beneficial effects of the utility model are: its head is made by flexible PVC or rubber, satisfy the rapid restorable requirement of weather strip, its base adopts cheap plastic material to make, its volume accounts for more than 80% of whole weather strip, therefore greatly reduces the cost of whole weather strip.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the sectional schematic diagram of axis of rotation part in the heat-insulating bridge-cut-off window.
Fig. 2 is the schematic diagram of Fig. 1 intermediate seal bar.
Fig. 3 is the sectional schematic diagram of axis of rotation part in the plastic-aluminum aluminium composite window.
The specific embodiment
11 is heat insulating strips of window frame 1 among Fig. 1, the 6th, and the sash axis of rotation.Inner seal bar 5, outside weather strip 3 and intermediate seal bar 2 are set on window frame 1.Wherein intermediate seal bar (referring to Fig. 2) is constituted by coextrusion process by the seal head 22 of rubber material and plastic material base 21.Its mounting means and invariant position, its seal head cooperates with the heat insulating strip 41 of sash 4, realizes sealing.
Referring to Fig. 3, the utility model can also be applied on plastic-aluminum aluminium composite window and the aluminum plastic compound window, when being applied on the plastic-aluminum aluminium composite window, the plastic material base 21 of intermediate seal bar has made up two seal heads 221 and 222 by coextrusion process, they cooperate with the plastic section bar of sash 4 respectively, realize twice sealing.
Claims (2)
1, a kind of combined type intermediate seal bar is characterized in that: it is to wear bar or coextrusion process constitutes by the base of the seal head of flexible PVC or rubber material and plastic material.
2, according to the described combined type intermediate seal of claim 1 bar, it is characterized in that: on the plastic material base, made up two seal heads with coextrusion process.
