A kind of switchover frame for inwardly opened window framework
Technical field
This utility model belongs to window technology field, relates to a kind of switchover frame for inwardly opened window framework.
Background technology
Building doors and windows mainly has two kinds of opening ways: 1, horizontally-opening windows and doors 2, sliding door and window, wherein horizontally-opening windows and doors
Divide again inward-opening door/window and external-open door and window, though which kind of opening ways, for construction safety and replacing glass just
Victory, erection of doors and windows code requirement glazing bead must assure that at indoor location, then has the structure spy of out-swinging casement
Point determines out-swinging casement and is combined sometimes for the frame system with inwardly opened window, for ensureing building external doors and windows
Watertight, airtight, be incubated, the multinomial performance requirement such as sound insulation, at this moment need to be equipped with in the frame system of inwardly opened window
Switchover frame structure completes the installation of out-swinging casement.Due to, the frame system of inwardly opened window is in processing, assembling process
Having deviation unavoidably to occur, the code requirement of industry is ± 1 millimeter.On market existing switchover frame design be
It is mounted directly switchover frame, owing to having processing and assembling generation meeting in the plate hole of the opening door-leaf that inwardly opened window is formed
With the deviation of theoretical value, cause switchover frame cannot push in the frame system of inwardly opened window, so existing technique
It is that switchover frame is gone processing by theoretical size reduction 2 millimeters, it is ensured that switchover frame all fits into inwardly opened window
In frame system, but the problem brought is between the surrounding border of switchover frame and the hole of inwardly opened window framework plate
Gap size is uneven, affects visual effect, reduces the watertightness of door and window, air-tightness.

Close fit, will not make again switchover frame 10 stuck, design ingenious.
Offering the strain shrinkage pool 37 of several depressions on the surface of cushion block 30, strain shrinkage pool 37 is towards turning
Connect frame 10.Faying face at cushion block 30 with switchover frame 10 arranges strain shrinkage pool 37, can switchover frame 10 with
In the extrusion process of cushion block 30, the strain of part cushion block 30 is transferred to strain in shrinkage pool 37, makes cushion block 30
Dependent variable bigger, make to have between cushion block 30 and window frame 20 bigger assemblage gap.
Cushion block 30 offers strain groove 33, in cushion block 30 is arranged on mounting groove 22 and strain groove 33 is flat
Row is in mounting groove 22, and strain groove 33 is just to the bottom surface to mounting groove 22.In the bottom of cushion block 30, strain is set
Groove 33, when switchover frame 10 extruding is arranged on cushion block 30, cushion block 30 entity part of strain groove 33 both sides
It is bent outwardly expansion, is squeezed in the both sides of mounting groove 22, the dependent variable of further high cushion block 30, makes switching
Between frame 10 with window frame 20, can to fill the scope being connected bigger in gap.
Offering escape groove 36 on cushion block 30, escape groove 36 is opened in the bottom of cushion block 30, escape groove
36 in "U" shaped, and escape groove 36 is opened in cushion block 30 both sides and bottom, and escape groove 36 blocks strain groove 33,
Card article 31 protrudes and is arranged on the two ends of escape groove 36, buckle boss 32 be squeezed after towards escape groove 36 side
To bending.I.e. card article 31 is arranged on the upper surface of cushion block 30, extends towards the bottom direction of cushion block 30, logical
Crossing the setting of escape groove 36, improve the card article 31 degree of depth at compression direction, as preferably, card article 31 is arranged
There are two row and are symmetrically distributed in the two ends of cushion block 30, escape groove 36 distribution corresponding with card article 31.At cushion block 30
Two ends escape groove 36 be set improve planarization when cushion block 30 is installed and stability, extrude card article 31, push away
Dynamic cushion block 30 slides in mounting groove 22, reduces frictional force, and the location of cushion block 30 is easy to adjust.
Further, strain groove 33 on offer strain bore 35, strain bore 35 be positioned at two escape groove 36 it
Between, as preferably, strain bore 35 is arranged on the middle part of cushion block 30.The setting of strain bore 35 decreases material,
Cushion block 30 is made to rotate and twist convenient.
Be provided with surrounding edge 11 in the side of switchover frame 10, surrounding edge 11 stretches out from the surface of switchover frame 10,
Surrounding edge 11 is arranged on the outer surface of switchover frame 10, and the opposite side of switchover frame 10 pushes against to rib 21, surrounding edge
11 block the joint at switchover frame 10 with window frame 20.As preferably, the inner peripheral surface of switchover frame 10 and rib
The end face of 21 is concordant.Arranging of surrounding edge 11 can block switchover frame when switchover frame 10 pushes against window frame 20
10 with the connecting sewing of window frame 20, protection seam clean and tidy, convenient dismounting and installing, meanwhile, beautify window frame
20, improve the aesthetics of window.
These are only the preferred embodiment of the application, not in order to limit the application, all the application's
