The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model. Example

[0021] like Figure 1-Figure 4 As shown, this embodiment adopts the following technical solution: it comprises a frame profile 1, the frame profile 1 is provided with a mounting groove 2 and a connecting cavity 3, two frame profiles 1 are connected by an angle code 4, and the angle code 4 is movably inserted in the connecting cavity 3;

[0022] It also contains:

[0023] Reinforcing ribs 5, which are several in number and are respectively fixedly arranged on the two inner side walls connecting the cavity 3. The reinforcing ribs 5 can improve the overall structural strength of the frame profile 1. The corner bracket 4 is provided with a strip groove matching the reinforcing ribs 5. The opening of the strip groove is provided with a chamfer 14. The setting of the chamfer 14 can not only make the installation and alignment process of the corner bracket 4 more convenient;

[0024] Dovetail strips 6, there are two dovetail strips 6, which are fixedly arranged on both sides of the outer wall of the frame profile 1, and the side edges of the frame profile 1 are abutted with a reinforcing connecting plate 7, which can not only provide protection for the corners of the frame profile 1, but also realize the force sharing of the corner code 4, thereby effectively improving the strength of the connection structure at the joint of the two frame profiles 1, and the outer corners of the reinforcing connecting plate 7 are all arc-shaped structures, which can effectively reduce the sharpness of the outer corners of the reinforcing connecting plate 7, and the dovetail strips 6 are clamped in the dovetail groove 8 opened on the inner wall of the reinforcing connecting plate 7;

[0025] The buffer pad 9 is fixedly arranged on the outer side wall of the reinforcement connecting plate 7. Through the force buffering characteristics of the buffer pad 9, the damage caused by the accidental collision between the personnel and the reinforcement connecting plate 7 can be effectively reduced. Example

[0026] like Figure 2 As shown, the present embodiment is improved on the basis of the first embodiment, a limiting rod 11 is movably arranged in the cylindrical groove 10 opened on the side wall of the dovetail strip 6, a spring 12 connected to the limiting rod 11 is fixedly arranged in the cylindrical groove 10, a groove matching the arc end of the limiting rod 11 is opened on the inner wall of the dovetail groove 8, and the connection limit between the dovetail strip 6 and the reinforcement connecting plate 7 can be achieved through the cooperation of the spring 12 and the limiting rod 11, a sealing strip 13 is fixedly arranged in the embedded groove opened on the inner wall of the reinforcement connecting plate 7, and the sealing strip 13 is set in conflict with the outer wall of the frame profile 1, the sealing strip 13 can improve the sealing between the reinforcement connecting plate 7 and the frame profile 1, and prevent rainwater from seeping into the cylindrical groove 10 and affecting the spring 12 and the limiting rod 11.

[0027] When using the utility model, the corner code 4 is inserted into the connecting cavity 3 of the frame profile 1, and the other end of the corner code 4 is inserted into the connecting cavity 3 of the frame profile 1 on the other side. After the two frame profiles 1 are spliced, the reinforcing connecting plate 7 is made to contact the upper side wall of the splicing place of the two frame profiles 1, and then the reinforcing connecting plate 7 is moved downward so that the dovetail strip 6 is contacted into the dovetail groove 8. At the same time, the limiting rod 11 is pushed by the thrust applied by the spring 12 to make the arc end of the limiting rod 11 contact into the groove to achieve the connection limit between the dovetail strip 6 and the reinforcing connecting plate 7. During the force-bearing process of the photovoltaic frame, the connection between the dovetail strip 6 and the frame profile 1 can make the reinforcing connecting plate 7 effectively share the force of the splicing place of the two frame profiles 1 and the corner code 4.

[0029] 1. The reinforcing ribs 5 can improve the structural strength of the frame profile 1, and the cooperation of the dovetail strips 6, the reinforcing connecting plates 7 and the buffer pads 9 can not only provide force sharing for the joints of the frame profile 1, improve the structural strength of the joints, but also provide protection for the corners of the frame to reduce safety risks;

[0030] 2. Through the cooperation of the limiting rod 11 and the spring 12, the connection between the dovetail strip 6 and the reinforcement connecting plate 7 can be limited, thereby preventing the reinforcement connecting plate 7 from being disassembled at will.
