Obtaining rainwater can be smoothly discharged under Gravitative Loads, and draining is more smooth, and resistance is lower, avoid rainwater and flow backward into interior, and
This hierarchic structure, which can also imitate, prevents mosquito from entering.
Embodiment 2
The utility model embodiment provides a kind of concealed discharge structure of ladder, and structure is substantially the same manner as Example 1,
Its difference is, on the basis of embodiment 1, has done following improvement, has further improved its service performance:
As shown in figure 4, sealing joint strip 10 has the mounting portion 1001 that is installed on window frame heat insulation section 7 and heat-insulated with sash
What profile 9 leant abuts against portion 1003, in general, window frame heat insulation section 7 is equipped with card slot, mounting portion 1001 is installed in card slot,
Fixing seal adhesive tape 10 avoids sealing joint strip 10 and falls off, and abuts against portion 1003 for abutting against sash heat insulation type when sash closure
On material 9, the gap between sash and window frame is effectively blocked, has been flowed backward so as to avoid rainwater into interior.
Mounting portion 1001 is equipped with hollow installation and squeezes cavity 1002, and when installation, hollow installation squeezes cavity 1002 can
With deformation, to facilitate mounting portion 1001 to be installed in card slot, after being installed, installation squeezes cavity 1002 and restores deformation, so that
Mounting portion 1001 firmly in conjunction with card slot, avoids sealing joint strip 10 and falls off.
Abut against portion 1003 and be equipped with hollow abut against and squeeze cavity 1004, abut against squeeze cavity 1004 can be in sash closure
Flexible deformation is generated, the portion of abutting against 1003 is avoided or sash heat insulation section 9 is uneven and generates permeable gap, so that abutting against portion
1003 with sash heat insulation section 9 is closer is bonded, further avoid rainwater and enter the room.
Sealing joint strip 10 is equipped with the sealing lip 1005 for being bonded sash heat insulation section 9, and sealing lip 1005 stretches to sash
Heat insulation section 9 and with the portion that abuts against 1003 be spaced be arranged, sealing lip 1005 is more prone to produce deformation, therefore can more fit to sash
On heat insulation section 9, extraneous wind-force is bigger, and sealing lip 1005 can be more fitted tightly on sash heat insulation section 9, further avoids
Rainwater enters the room.
Mounting portion 1001, abut against portion 1003 and sealing lip 1005 setting be integrated, sealing joint strip 10 be ethylene propylene diene rubber
Rubber adhesive tape made of material when production, by extrusion molding of mold, can either improve production efficiency, in turn ensure peace
Dress portion 1001 abuts against integrality and fastness between portion 1003 and sealing lip 1005.
10 surface of sealing joint strip is coated with ageing-resistant wearing layer, which generallys use oil layer, specific to advise
Lattice can select compatible grease according to 10 material of sealing joint strip, no longer illustrate one by one herein.
Sash heat insulation section 9 has the gradient towards the surface of window frame heat insulation section 7, and sash heat insulation section 9 is located at sealing lip
The distance of 1005 1 side end faces to 7 end face of window frame heat insulation section is greater than far from 1,005 1 side end face of sealing lip to window frame heat insulation section
7 end faces, so that abutting against gap between portion 1003 and sash heat insulation section 9 by being gradually reduced inside outside, extraneous wind-force is bigger, top
Relying part 1003 can be more fitted tightly on sash heat insulation section 9, further avoided rainwater and entered the room.
In use, sealing joint strip 10 is installed in card slot on window frame heat insulation section 7, when sash is closed, extruding is abutted against
Cavity 1004 generates flexible deformation, fits closely so that abutting against portion 1003 with sash heat insulation section 9, when outdoor air pressure is bigger,
Abut against the fitting sash heat insulation section 9 that portion 1003 and sealing lip 1005 can be even closer, sealing effect is better, wind and rainwater also without
Method invades indoor side, avoids rainwater and flows backward into interior.
