[0027] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments:

[0028] Refer to Figures 1 - 10 , a profile connection structure, including a connection structure main body, and the connection structure main body includes a first connection piece 1, a second connection piece 2 and a mounting member 3.

[0029] As one of the embodiments, there are two pieces of both the first connection piece 1 and the second connection piece 2. Among them, there is a gap between the two first connection pieces 1, and the two are connected into one body by a plurality of mounting members 3; there is also a gap between the two second connection pieces 2, and the two are connected into one body by a plurality of mounting members 3. Further, the second connection piece 2 is fixedly installed on the first connection piece 1 to form the connection structure main body.

[0030] As one of the embodiments, the shape of the first connection piece 1 is "T", including a strip-shaped part arranged horizontally in the upper part and a strip-shaped part arranged vertically in the lower part; the shape of the second connection piece 2 is "L", including a strip-shaped part arranged horizontally in the upper part and a strip-shaped part arranged vertically in the lower part.

[0031] In this embodiment, after the mounting member 3 connects the two first connection pieces 1 into one body, its two ends respectively pass through the first connection piece 1 and extend outside the first connection piece 1, that is, there is an exposed part after passing through it, and holes and grooves for installing fasteners are provided at the exposed parts at both ends; after the mounting member 3 connects the two second connection pieces 2 into one body, its two ends respectively pass through the second connection piece 2 and extend outside the second connection piece 2, that is, there is an exposed part after passing through it, and holes and grooves for installing fasteners are provided at the exposed parts at both ends.

[0032] As one of the implementation manners, the mounting member 3 includes an intermediate portion 31 and outer end portions 32 located at both ends of the intermediate portion 31. The diameter of the outer end portion 32 is smaller than that of the intermediate portion 31. The end walls of the intermediate portion 31 that extend beyond the outer end portion 32 are attached to the inner side walls of the two first connecting pieces 1 and the inner side walls of the two second connecting pieces 2, and the outer end portion 32 is inserted through the first connecting piece 1 and the second connecting piece 2.

[0033] In this embodiment, the first connecting piece 1 includes a first longitudinal portion 11 inserted into the first profile 4, a first transverse portion 12 inserted into the second profile 5, and a second transverse portion 13 inserted into the third profile 6. The first longitudinal portion 11 is the strip-shaped portion longitudinally arranged at the lower part mentioned above, and the first transverse portion 12 and the second transverse portion 13 constitute the strip-shaped portion transversely arranged at the upper part mentioned above.

[0034] Corresponding mounting members 3 are respectively arranged on the first longitudinal portion 11, the first transverse portion 12, and the second transverse portion 13, for example, two mounting members 3 are respectively arranged on each portion.

[0035] In this embodiment, the second connecting piece 2 includes a second longitudinal portion 21 inserted into the first profile 4 and a third transverse portion 22 inserted into the fourth profile 7. The second longitudinal portion 21 is the strip-shaped portion longitudinally arranged at the lower part mentioned above, and the third transverse portion 22 is the strip-shaped portion transversely arranged at the upper part mentioned above.

[0036] Corresponding mounting members 3 are arranged on the third transverse portion 22, for example, two mounting members 3 are arranged. Of course, according to actual needs, one or more mounting members 3 can also be arranged on the second longitudinal portion 21.

[0037] In this embodiment, the second connecting piece 2 further includes a folded edge 23 formed by bending. The folded edge 23 is formed by bending at the second longitudinal portion 21. The second connecting piece 2 is fixed to the first connecting piece 1 through the folded edge 23. The fixing method can be fixing through fasteners or welding, etc. When fixing, the folded edge 23 can be attached to the outer side wall of the first connecting piece 1 and then fixed.

[0038] As one of the implementation manners, the mounting members 3 arranged on the first longitudinal portion 11 are arranged between the two second connecting pieces 2, such as Figure 1 shown.

[0039] Such as Figure 5 , Figure 9 shown, a plurality of mounting openings are provided at the upper end of the first profile 4, namely a first mounting opening 41 provided at the upper end of the left side wall of the first profile 4, a second mounting opening 42 provided at the upper end of the right side wall of the first profile 4, and a third mounting opening 43 provided at the upper end of the front side wall of the first profile 4.

[0040] Among them, the first installation opening 41 is used for assembling the second profile 5, the second installation opening 42 is used for assembling the third profile 6, and the third installation opening 43 is used for assembling the fourth profile 7.

[0041] After inserting the connection structure main body to the upper end of the first profile 4, both the first longitudinal part 11 and the second longitudinal part 21 are arranged inside the first profile 4, the first transverse part 12 is arranged at the first installation opening 41, the second transverse part 13 is arranged at the second installation opening 42, and the third transverse part 22 is arranged at the third installation opening 43. Then, the second profile 5 is sleeved on the first transverse part 12 and pushed to the first installation opening 41, the third profile 6 is sleeved on the second transverse part 13 and pushed to the second installation opening 42, and the fourth profile 7 is sleeved on the third transverse part 22 and pushed to the third installation opening 43. And the through holes for installing fasteners on the corresponding profiles are made to correspond to the holes on the corresponding mounting parts 3. Then, each profile is fixedly connected to the connection structure main body through fasteners to form a connection member as Figure 4 shown.

[0042] The connection structure main body can connect a plurality of profiles arranged in the left - right direction, front - back direction, and up - down direction into one body, and after connection, the connection structure main body is mostly or entirely hidden inside by the profiles. At least after the profiles are assembled, from the lower perspective, there is no exposed visible part of the connection structure main body, as Figure 10 shown.

[0043] After the profiles are connected by the connection structure main body, other components such as sun - shading plates usually need to be installed above it. Therefore, after the profiles are assembled, from the upper perspective, the fact that there are some exposed visible parts of the connection structure main body does not affect the effect of the finished product, and the other installed components can effectively block and cover the exposed parts.

[0044] It should be noted that for the first profile 4, the second profile 5, the third profile 6, and the fourth profile 7 referred to in this article, the ends for connecting to the connection structure main body all have openings for the corresponding parts of the connection structure main body to insert, and their interiors are integrally hollow or at least have cavities for accommodating the corresponding parts of the connection structure main body, as Figures 6 - 9 shown.

[0045] The above - mentioned embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
