Background
At present, a plurality of frame profiles (including window frame profiles and door frame profiles, the same applies below) applied to doors and windows are manufactured by aluminum profiles. For the glass door or window needing heat preservation and heat insulation, if the frame section is made of single aluminum material, the heat transfer speed is high, which is not beneficial to indoor and outdoor heat preservation and heat insulation. At present, a bridge cut-off structure is arranged in the middle of an aluminum profile to prevent the transmission of internal and external heat, so that the effects of heat preservation and heat insulation are achieved. The most common structure is the structural form of outer aluminum profile, plastic nylon profile and inner aluminum profile. The plastic nylon section bar in the structural form mainly plays a role of 'bridge cut-off' of heat transfer, is used for slowing down the transfer of indoor and outdoor heat and achieves the effects of heat preservation and heat insulation. However, it has many disadvantages: 1. the consumption of the aluminum material is more; because the width of the inner aluminum profile and the width of the outer aluminum profile in the profile are larger, the consumption of aluminum materials is more during processing and manufacturing, the consumption of raw materials is increased, and the manufacturing cost is improved. 2. The section bar has a complex structure but lacks functions; the profile itself has only a simple supporting and decorative function. 3. The application range is limited; the sliding window is only suitable for common sliding window and door structures, but not for sliding window and door structures and other special opening window and door structures, such as sliding windows with leaves separated from the plane of a window frame. 4. When the window frame or the door frame is assembled, the stability and the integrity are poor; when the traditional section bar is connected with the mullion and the cross beam or the mullion and the upper cross beam and the lower cross beam, screws cannot be conveniently used for reinforcement, and after the frame is assembled, the bearing is low and the corner is easy to crack. 5. The plastic nylon section bar in the existing section bar has less thickness, thereby leading the heat preservation and insulation performance to be lower; because the plastic nylon section bar as the 'broken bridge' is narrower, the 'broken bridge' effect is not obvious, and on the other hand, because the integral structure is unstable, the corner of the assembled fan blade is easy to crack, and the indoor heat is easy to dissipate.

Detailed Description
Example one
Referring to fig. 1 to 4, the frame section of the present invention is a long strip; the components of the frame profile described below all have the same length. The heat insulation structure comprises an outer frame body 10, an inner frame body 20 and heat insulation strips 30; the outer frame body 10 and the inner frame body 20 are generally made of aluminum or aluminum alloy materials and mainly play a supporting role in application; the heat insulation strip 30 is generally made of plastic nylon material, mainly plays a role in heat insulation and heat preservation, and reduces the using amount of aluminum materials. A pair of inner clamping and pressing grooves 11 are formed in the inner surface of the outer frame body 10, and a pair of outer clamping and pressing grooves 21 opposite to the pair of inner clamping and pressing grooves 11 are formed in the outer surface of the inner frame body 20; the pair of inner clamping grooves 11 and the pair of outer clamping grooves 21 are used for firmly assembling the heat insulation strips 30. The number of the heat insulation strips 30 is two. Two ends of the two heat insulation strips are respectively meshed and rolled with the pair of inner clamping and pressing grooves 11 and the pair of outer clamping and pressing grooves 21 into a whole; the rectangular air heat insulation cavity is formed by the outer frame body 10, the two heat insulation strips 30 and the inner frame body 20, so that the frame section has good heat insulation performance. The mutual occlusion means that the concave-convex structures which are mutually inosculated are occluded together by matching, and then the concave-convex structures are rolled into a whole with certain binding force; the process can adopt the existing common processing technology. Through the connection, the connection between the two parts is reliable and firm, the consumption of the section main body can be effectively reduced, and the width of the heat insulation cavity is increased. The pair of outer clamping grooves 21 have a mounting width W so that screws can pass through the outer clamping grooves vertically to mount the frame profile and other frame profiles connected with each other firmly, such as the upper horizontal frame or the joint between the lower horizontal frame and the mullion in the second embodiment.
The outer frame 10 further comprises an outer cavity 12 and a baffle 13; the pair of inner clamping and pressing grooves 11 are formed at the edges of the inner surface of the outer cavity 12 (shown as the rightmost plane of the outer cavity 12) for mounting the heat insulating strips 30. The "inner surface of the outer cavity" as referred to herein includes a plane extending in the direction of the plane of the inner surface of the outer cavity; as shown in fig. 3 and 4, includes planes extending up and down both sides. FIG. 1 shows, including a plane extending upwardly; FIG. 2 shows, including a downwardly extending flat surface; both of fig. 3 and 4 include upwardly and downwardly extending flats. The pair of inner clamping and pressing grooves 11 comprises an upper inner clamping and pressing groove and a lower inner clamping and pressing groove, wherein the upper inner clamping and pressing groove is respectively positioned on the upper edge part of the inner surface of the outer cavity body, and the lower inner clamping and pressing groove is positioned on the lower edge part of the inner surface and is respectively used for installing the two heat insulation strips 30; as shown in fig. 1, the upper inner clamping groove is formed on the upper edge of the extension plane of the inner surface, and the lower inner clamping groove is formed on the lower edge of the inner surface of the outer cavity. The baffle 13 comprises two blocks respectively positioned at two sides of the outer cavity 12. The outer surface of the outer cavity and the outer surface of the baffle are positioned on the same plane to form the outer decorative surface of the frame section. The baffle 13 is formed by directly extending the surface of the outer cavity 12 or bending the surface after extending. As shown in fig. 3 and 4, the baffles 13 on both sides of the frame-shaped material are formed by extending and bending the inner surface of the outer cavity 12; as shown in fig. 1 and 2, one of the baffles at both sides of the frame profile is formed by extending and bending the inner surface of the outer cavity 12, and the other baffle 13 is formed by directly extending the outer surface of the outer cavity 12 and is used as an outer support when being used as a door window frame; the integrity is strong, and the structural strength is reliable. At least one of the baffle plates is provided at its edge with an inwardly directed first strip slot 14 for fitting a strip. As shown in fig. 1 and 2, only one of the baffle plates is provided with a first strip notch 14 at its edge. As shown in fig. 3 and 4, the edge parts of the baffle plates of the frame section bar are provided with first sealing strip notches 14;
the inner frame 20 also includes an inner body 22. The pair of outer clamping and pressing grooves 21 are arranged on two side parts of the outer surface of the inner main body; similarly, the pair of outer clamping grooves 21 includes an upper outer clamping groove and a lower outer clamping groove respectively located at the upper edge portion and the lower edge portion of the inner surface, and are respectively used for installing the two heat insulating strips 30. The inner main body 22 has a width consistent with the distance between the edges of the pair of inner clamping and pressing grooves 11, namely, after the pair of outer clamping and pressing grooves 21 are arranged at the two sides of the outer surface of the inner main body, the distance between the edges of the pair of outer clamping and pressing grooves is the same as the distance between the edges of the pair of inner clamping and pressing grooves 11 on the outer frame body; on one hand, the heat insulation strips are convenient to assemble, and the assembled heat insulation strips are in a parallel shape; on the other hand, the material is saved. At least one edge of the inner main body is bent inwards to form a mounting groove 23, and the inward bent part is far away from the pair of outer clamping and pressing grooves and is used for mounting the inner pressing frame. As shown in fig. 3 and 4, both side portions of the inner body are respectively bent inward to form mounting grooves 23; as shown in fig. 1 and 2, only one side of the inner body is bent inwards to form a mounting groove 23; the upper edge portion is shown in fig. 1, and the lower edge portion is shown in fig. 2.
Referring to fig. 3, the outer frame 10 and the inner frame 20 are both symmetrical structures, and the formed section bar is also symmetrical. For example, the two baffles on both sides of the outer cavity 12 are symmetrical along the central axis of the outer cavity 12. Correspondingly, the central region of the inner body 22 constitutes an inner cavity 24, which is convex towards the inside; the vertical center line Q (approximate position of the mounting screw for connecting the frame profiles) of the pair of outer clamping and pressing grooves 21 is positioned in the inner cavity 24; when the door and window frames are assembled through the screws, the screws penetrate through the inner cavity through the centers of the outer clamping and pressing grooves, the occupied size of the outer clamping and pressing grooves 21 in the width direction of the section bar is reduced, the width of the heat insulation strip is correspondingly ensured, and the heat insulation performance of the heat insulation strip is improved; meanwhile, when the left and right installed fan blades have different functions (for example, one side is a fixed fan, and the other side is a push-pull opening fan), the distance between the vertical central planes of the fan blades at the two sides is reduced, the dissipation of internal and external heat can be effectively reduced, and the heat preservation and heat insulation performance is further improved. The inner surface of the inner cavity forms a support 25 inwards, and the support 25 is in a transverse T shape; the inner pressing frame is mainly used for supporting and fixing the inner pressing frame of the fan and keeping the whole consistency. The middle region is the region between a pair of outer snap grooves. The frame section bar of the structure is mainly used as a mullion of a door and a window frame.
Referring to fig. 4, the outer frame 10 has a symmetrical structure. The middle area of the inner main body 22 in the inner frame 20 forms an inner cavity 24 for reinforcement, and the vertical center line Q of the pair of outer clamping and pressing grooves 21 is located in the inner cavity 24 (the principle is the same as that of the embodiment in fig. 3); the outer surface of one edge of the inner cavity 24 extends horizontally inwards to form a support cavity 26 with a bend. The interior of the supporting cavity 26 can adopt a cavity structure (shown in fig. 4), so that on one hand, the material consumption is saved; on the other hand, the strength and the supporting capacity of the supporting cavity 26 are improved.
Referring to fig. 1 and 2 again, the outer frame 10 is asymmetric. One of the side baffles, i.e. one of the baffles at both sides of the frame profile (the lower baffle is shown in fig. 1, and the upper baffle is shown in fig. 2) is formed by directly extending the outer surface of the outer cavity 12 and is used as an outer support of the profile; a first sealing strip notch 14 is arranged at the edge part of the other side baffle (such as the upper side baffle in figure 1); the first strip channel 14, shown in figure 1, has a channel towards the right, i.e. towards the inside of the frame profile, for fitting a strip sealing the gap between the sash glass and the sash frame. On the same side (such as the lower side in fig. 1 and the upper side in fig. 2) of the outer support body, the inner surface of the inner main body is subjected to a structural reinforcement treatment and then extends inwards to form an inner support body 27; the bottommost part of the inner supporter 27 and the bottommost part of the outer supporter are in the same horizontal plane (as shown by a horizontal line L in fig. 1), so that the installation is stable, and the uniform stress of the whole body after the installation is ensured. The structural reinforcement processing means that the connection position is connected by adopting a cavity type structure (shown in figure 2) or the cavity type structure (shown in figure 1) is adopted from the connection position to the inner support body, so that the connection strength of the connection position and the support capability of the inner support body are improved.
