The abutting plug-in and the positioning edge 7 are respectively abutted on the front and rear sides of the positioning frame 5. A plurality of positioning grooves 2 are provided in the middle of the rear side of the splicing frame 1. A positioning plug-in is installed in the positioning groove 2. The positioning plug-in includes a plug-in body 8, a positioning screw 9 and an abutting plug-in. The plug-in body 8 is set to a cross shape. The plug-in body 8 includes an integrally formed connecting block and a connecting rod extending to the four sides. The end of the connecting rod is provided with a positioning block extending to both sides. Mounting grooves are provided on both sides of the connecting rod. The positioning bolt is rotatably connected to the connecting block. The abutting plug-in is fixed to The connecting rod is in the installation groove, and the connecting rod is matched with the installation groove in a concave-convex manner. The interference plug-in includes a sliding plug plate 10, an adjusting beam plate 11, a contact seesaw 12 and a linkage seesaw 13. The sliding plug plate 10 is inserted in the installation groove, and the two ends of the adjusting beam plate 11 are rotatably connected with adjusting screws, and the adjusting screws are threadedly connected to the splicing frame 1. The contact seesaw 12 and the linkage seesaw 13 are integrally formed at a bending angle, and the contact seesaw 12 and the linkage seesaw 13 are hinged on the sliding plug plate 10. The contact seesaw 12 and the linkage seesaw 13 are connected to the sliding plug plate 10. A reset torsion spring is arranged between the sliding plug plates 10, the contact rocker 12 contacts the rear side of the positioning frame 5, the front end of the positioning screw 9 is threadedly connected to the splicing frame 1, the contact plug-in is fixed on the plug-in body 8, the contact plug-in contacts the rear side of the solar cell panel, and the positioning groove 2 is provided with a limiting groove 4 corresponding to the position of the contact rocker 12, the width of the limiting groove 4 is greater than the width of the contact rocker 12, and the width of the limiting groove 4 is less than the width of the linkage rocker 13, and the linkage rocker 13 contacts the inner wall of the positioning groove 2.

[0030] Working principle:

[0031] In the utility model, the solar cell assembly 6 connected with the positioning frame 5 is inserted into the installation frame, the positioning edge 7 is against the front side of the positioning frame 5, and then the positioning plug is inserted into the positioning groove 2. Under the action of the torsion spring, the linkage seesaw 13 is tilted forward. During the insertion process of the positioning plug, since the width of the linkage seesaw 13 is greater than the width of the limiting groove 4, the front end of the linkage seesaw 13 will be against the inner upper edge of the positioning groove 2, gradually against the linkage seesaw 13 to rotate backward, and the hinged contact seesaw 12 will rotate outward, extend through the limiting groove 4 to the inside of the splicing frame 1, and face the positioning frame 5. , the positioning plug-in continues to be inserted until the part of the interfering seesaw 12 extending out of the splicing frame 1 contacts the positioning frame 5, and the positioning plug-in is fixed to the splicing frame 1 by the positioning nut to complete the installation of the solar cell assembly 6 and the positioning frame 5. In addition, the height of the sliding plug-in plate 10 can be adjusted by adjusting the nut, that is, adjusting the height of the interfering seesaw 12 so that there is a suitable interfering pressure between the interfering seesaw 12 and the positioning frame 5, avoiding the formation of a gap between the interfering seesaw 12 and the positioning frame 5, causing the positioning frame 5 to shake, or the excessive interfering pressure between the interfering seesaw 12 and the positioning frame 5 causing deformation;

[0032] When the splicing area of ​​the solar cell assembly 6 needs to be expanded, multiple splicing frames 1 can be connected to combine the positioning half grooves 3 into a positioning groove 2, and then connected and fixed by a positioning plug-in.

[0033] Meanwhile, when a single solar cell assembly 6 is damaged, the interference plug-in corresponding to the solar cell assembly 6 can be removed to release the interference of the interference rocker 12 on the positioning frame 5 of the solar cell assembly 6, thereby achieving the purpose of quickly disassembling the solar cell assembly 6.
