[0001] The utility model relates to the field of door and window structure design and manufacturing, in particular to a high-performance heat-insulating fan frame. Background Art

[0002] The thermally insulated aluminum system windows currently on the market, regardless of frame or sash, all adopt a structure in which inner and outer aluminum materials are composited with nylon insulation strips in the middle. This structure has greatly improved the thermal insulation performance compared to pure aluminum profiles and is widely used both at home and abroad. So, are there other forms that can further reduce heat conduction and improve thermal insulation performance? This is a topic that the door and window industry has been studying.

[0003] The existing structural form has greatly improved the thermal insulation compared to the earliest steel structure windows, but a large amount of heat will still be conducted inward through the aluminum outside the frame and the aluminum profile outside the fan, through the thermal insulation cavity and the gap between the frame and the fan and the glass. Even if the thermal insulation material is filled in the thermal insulation cavity, the thermal insulation performance can only be slightly improved. Utility Model Content

A card slot 5 is provided on the inside of the second frame body 2. A glass holder 6 is provided above the lower frame body 4. One end of the glass holder 6 is clamped in the card slot 5 of the second frame body 2. Insulation cotton 7 is provided above the glass holder 6. The glass 3 is located above the insulation cotton 7. The inner side of the lower frame body 4 is connected with the second frame body 2. An external pressure line slot 8 is provided on the outer side of the top of the lower frame 4, and the lower frame 4 is clamped with the fan external pressure line 9 through the external pressure line slot 8. The inner side of the fan external pressure line 9 is provided with a fan external strip 10, which passes through the top of the fan external pressure line 9 and extends downward. The bottom formed by the extension of the fan external strip 10 is clamped with the outer side of the lower frame 4, and the outer side of the extended part of the fan external strip 10 is connected to the first frame 1. The bottom of the lower frame 4 has a stepped structure from the inside to the outside, and the top of the inner side of the second frame 2 is also connected to the fan inner rubber strip 11.

[0024] The cross section of the glass support 6 is L-shaped, and the bottom of the L-shaped glass support 6 is engaged in the slot 5 of the second frame 2 .

[0025] A composite part 12 is provided on the inner side of the lower frame 4, and the composite part 12 is connected to the second frame 2. A strip card slot 13 is provided on the outer side of the lower frame 4. In order to ensure that the surface of the fan outer strip 10 is smooth, a strip protrusion 14 is provided on the inner side of the bottom of the fan outer strip 10, and the strip protrusion 14 is engaged with the strip card slot 13.

[0026] In order to enhance the anti-deformation capability of the lower frame 4, the stepped structure at the bottom of the lower frame 4 forms a plurality of steps 16, and each step 16 is inclined upward by 2° to 3°.

[0027] The lower frame 4 is provided with a cavity 15 for installing the connecting angle bracket.

[0028] A protrusion 17 is provided at the head of the fan outer pressure wire 9, and the protrusion 17 is clamped with the fan outer strip 10. The foot of the fan outer pressure wire 9 is tilted downward, and the foot of the fan outer pressure wire 9 is clamped in the outer pressure wire clamping groove 8.

[0029] The lower frame 4 and the fan outer pressure line 9 are both made of PA66GF25 nylon material.

[0030] A screen sash 18 is provided between the sash outer strip 10 and the first frame 1 .

[0031] Working principle: the lower frame 4 is integrated with the second frame 2 through the composite part 12, and formed into a whole through the corner code, and then the glass holder 6 is buckled into the glass holder slot 5, and the heat insulation cotton 7 is placed on the glass holder 6, and then the glass 3 is put in and pushed to the side of the second frame 2, leaving the position of the external pressure line slot 8 empty, and the fan external pressure line 9 is installed, and then the fan external wing strip 10 is installed on the fan external pressure line 9, and the wing strip protrusion 14 at the bottom of the fan external wing strip 10 is snapped into the wing strip slot 13 to straighten and tighten the fan external wing strip 10, and then the glass 3 is moved to the position of contacting the fan external wing strip 10, leaving the installation position of the fan internal rubber strip 11 empty, and the fan internal rubber strip 11 is pressed in. At this point, the insulation fan frame assembly is completed.

[0032] The overall window structure is a hidden sash structure. When the window is closed, the screen sash 18 and the first frame 1 are in a compressed state, and are compressed and sealed by rubber strips, which provide the window sash with inward support as a whole. In addition, the outer sash strip 10 covers the entire sash, which avoids the lower frame 4 of PA66GF25 and the outer sash pressure line 9 from direct sunlight and direct heat transfer, which can effectively enhance its service life and reduce the factors of sunlight aging. In addition, after the glass 3 is installed, the weight of the glass 3 is transferred to the glass support 6 through the insulation cotton 7. There is a 0.5mm gap between the glass support 6 and the lower frame 4. The force will first be transmitted to the second frame 2 through the glass support 6, making the second frame 2 the main force-bearing component of the gravity of the glass 3, reducing the influence of the gravity of the glass 3 on the lower frame 4, and reducing its deformation factor.
