Specific implementation mode

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0023] Embodiment

[0024] Please refer to Figures 1 to 9As shown in the figure, this embodiment provides an external flat part for assembling broken bridge aluminum doors and windows, which is used for the corner joint of two broken bridge aluminum profiles 2; a notch 21 is provided on the side surface of the broken bridge aluminum profile 2; the notch 21 is in a T shape and includes an outer groove 211 and an inner groove 212; the flat part 1 is installed at the position where the two notches 21 of the two broken bridge aluminum profiles 2 are communicated; the flat part 1 includes a limiting part 11; the limiting part 11 includes a first limiting part 11A for inserting into the outer groove 211 of the first broken bridge aluminum profile 2A and a second limiting part 11B for inserting into the outer groove 211 of the second broken bridge aluminum profile 2B; the flat part 1 further includes a connecting part 12; the connecting part 12 includes a first connecting part 12A for inserting into the inner groove 212 of the first broken bridge aluminum profile 2A and connected to the first limiting part 11A, and a second connecting part 12B for inserting into the inner groove 212 of the second broken bridge aluminum profile 2B and connected to the second limiting part 11B; the two outer side surfaces in the width direction of the first limiting part 11A and the corresponding outer side surfaces in the width direction of the second limiting part 11B are located on the same plane; the width L5 of the first limiting part 11A, the width L5 of the second limiting part 11B are the same as the width L1 of the outer groove 211 of the broken bridge aluminum profile 2. In this embodiment, the angle formed by the first limiting part 11A and the second limiting part 11B is the same as the corner joint angle R of the two broken bridge aluminum profiles 2.

[0025] Refer to again Figure 6 and Figure 7 As shown in the figure, on the two side surfaces in the width direction of one end of the first limiting part 11A away from the second limiting part 11B, there are provided guiding parts 111; on the two side surfaces in the width direction of one end of the second limiting part 11B away from the first limiting part 11A, there are also provided guiding parts 111. In this embodiment, the guiding parts are inclined surfaces, which narrow inwards in the width direction towards the end, so that the width of the ends of the first limiting part 11A and the second limiting part 11B is smaller than the width L1 of the outer groove 211; this makes it easier for the limiting part to be inserted into the outer groove.

[0026] Refer to again Figures 4 to 7 、 Figure 9As shown, on both sides in the width direction at one end of the first connecting portion 12A away from the second connecting portion 12B, inner support portions 13 are respectively provided; the outer sides of the two inner support portions are used to be in close contact with the inner groove 212; on both sides in the width direction at one end of the second connecting portion 12B away from the second connecting portion 12A, inner support portions 13 are also respectively provided. In this embodiment, the inner support portions mainly enable the flat part to be stably fixed in the inner groove. Specifically, the inner support portion 13 has an outwardly convex arc-shaped structure; the outer width L8 of the mouths of the two inner support portions 13 at one end away from the connecting portion is smaller than the width L2 of the inner groove 212. In this embodiment, the flat part is an injection molded part and has a certain elasticity, and the maximum width L7 of the outer widths of the two inner support portions 13 can be slightly larger than the width L2 of the inner groove 212, so that the two inner support portions 13 are in close contact with the inner groove 212.

[0027] Referring again to Figure 5 、 Figure 9 As shown, an avoidance space 14 is formed between the first connecting portion 12A and the two inner support portions 13 provided thereon, for avoiding the glue injection holes 22 on the bottom surface of the notch 21; an avoidance space 14 is formed between the second connecting portion 12B and the two inner support portions 13 provided thereon.

[0028] Referring again to Figure 7 、 Figure 9 As shown, the maximum width L6 of the first connecting portion 12A and the maximum width of the second connecting portion 12B are less than or equal to the width L2 of the inner groove 212. In this embodiment, the first connecting portion 12A and the second connecting portion 12B are arranged in an L shape, and their main function is to connect the limiting portion 11 and the inner support portion 13. The connecting portion 11 can provide a limiting function (the maximum width is equal to the width of the inner groove 211), or can not provide a limiting function (the maximum width is less than the width of the inner groove 211).

[0029] Referring again to Figure 6 As shown, the first connecting portion 12A is arranged to be narrowed in the thickness direction from the end close to the second connecting portion 12B towards the end away from the second connecting portion 12B; the second connecting portion 12B is arranged to be narrowed in the thickness direction from the end close to the first connecting portion 12A towards the end away from the first connecting portion 12A; the maximum thickness L4 of the first connecting portion 12A, the maximum thickness of the second connecting portion 12B are consistent with the depth L3 of the inner groove 212. In this embodiment, setting the maximum thickness of the connecting portion to be consistent with the depth of the inner groove can make the flat part match the inner groove in the thickness direction, and the positioning is more accurate and reliable; the narrowing arrangement can make the first connecting portion and the second connecting portion easier to be inserted into the inner groove.

[0030] An external flattening part for assembling a broken bridge aluminum window and door in this embodiment. When assembling the corner joints of the broken bridge aluminum profiles, first place fixing and supporting structures such as corner codes inside two broken bridge aluminum profiles. Then, close the corner joints of the two broken bridge aluminum profiles with the smallest spacing left. Next, insert the two pairs of supporting parts of the flattening part in this embodiment into the inner grooves of the notch openings of the two broken bridge aluminum profiles respectively. Continue to close the broken bridge aluminum profiles until the connecting part of the flattening part is completely inserted into the inner groove. Synchronously, the limiting part of the flattening part is also completely inserted into the outer groove.

[0031] An external flattening part for assembling a broken bridge aluminum window and door in this embodiment. Since the side faces in the width direction of the first limiting part and the second limiting part are correspondingly on the same plane, after the corner joint is completed, under the action of the first limiting part and the second limiting part, the visible surfaces of the two broken bridge aluminum profiles will be flattened.

[0032] The above embodiments should not limit the present invention in any way. Any technical solutions obtained by means of equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
