[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

[0021] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
[0022] The inventor of the present solution has found that in the prior art, the T-shaped connection structure of aluminum profiles is usually fixed in a multi-stage single dimension, that is, a plate is used for fixing in the plane, and a right-angle plate is installed at the 90-degree corner for fixing. However, when using the above-mentioned fixing method, the relative position adjustment is cumbersome, and displacement is easy to occur during the tightening process of different dimensions, resulting in final dimensional deviation. At the same time, for segmented fixing, when facing irregular force on the profile, that is, the force direction deviates from the original X-axis, Y-axis, and Z-axis, stress concentration is easy to occur, resulting in deformation or even damage of the concentration point. This embodiment provides the following solution:
[0023] like Figure 1 to Figure 2 As shown, this embodiment provides a T-shaped profile connection and fixing structure, including a first connection fixing member 3 for connecting a main profile 1 and a connecting profile 2, second connection fixing members 4 for connecting the connecting profile 2 are connected to both sides of the first connection fixing member 3, and a third connection fixing member 5 for connecting the main profile 1 is connected to one side of the second connection fixing member 4. The second connection fixing member 4 is perpendicular to the first connection fixing member 3, and the third connection fixing member 5 is perpendicular to the second connection fixing member 4.
[0024] It should be noted that the connecting profile 2 is vertically connected to the main profile 1 to form a T shape, the first connecting fixture 3 is respectively connected to the top of the main profile 1 and the connecting profile 2, the second connecting fixture 4 is connected to both sides of the connecting profile 2, and the third connecting fixture 5 is connected to one side of the main profile 1, thereby forming an integrated fastening to prevent the force direction of the profile from deviating from the original X-axis, Y-axis, and Z-axis, thereby avoiding stress concentration and preventing damage to the profile.
[0025] Specifically, the first connecting fixture 3, the second connecting fixture 4 and the third connecting fixture 5 are all sheet metal parts, the two second connecting fixtures 4 are symmetrical to each other, and the two third connecting fixtures 5 are symmetrical to each other. The second connecting fixture 4 is formed by bending both sides of the first connecting fixture 3, and the third connecting fixture 5 is formed by bending one side of the second connecting fixture 4.
[0026] It should be noted that the bent parts of the first connecting fixture 3 and the second connecting fixture 4 fit the surface of the connecting profile 2, so that the fasteners and the profile are subjected to the same angle of force, further avoiding stress concentration on the fasteners when the profile is subjected to irregular force.
[0027] Further, the first connection fixture 3 is connected with a reinforcing rib 31, and one end of the reinforcing rib 31 is provided with an inclined surface 311. The reinforcing rib 31 is provided at the middle position of the first connection fixture 3, and the first connection fixture 3 is provided with first connection holes 32 located on both sides of the reinforcing rib 31. The second connection fixture 4 is provided with a second connection hole 41, and the third connection fixture 5 is provided with a third connection hole 51, and the second connection holes 41 and the third connection holes 51 are evenly distributed in a matrix.
[0028] It should be noted that the reinforcement rib 31 welded on the first connection fixture 3 increases the strength of the main force-bearing surface of the fastener under normal force conditions of the profile, and the inclined surface 311 set at one end of the reinforcement rib 31 reduces the volume and area of the reinforcement rib 31, minimizes the probability of collision with other objects, and increases safety during installation. Bolts are screwed into the first connection hole 32, the second connection hole 41, and the third connection hole 51, respectively, so that the first connection fixture 3 is fastened to the main profile 1 and the connecting profile 2, the second connection fixture 4 is fastened to the connecting profile 2, and the third connection fixture 5 is fastened to the main profile 1.
[0029] In summary, the embodiment of the utility model provides a T-shaped profile connection fixing structure, which adopts an integrated bending structure, takes into account the parallelism and verticality verification of the profile before installation, and prevents the profile from offsetting during the installation and fastening process. The bending angle can fit the profile surface as closely as possible to avoid stress concentration under irregular force.
