Like the sealing of the automobile door.

[0032] 3. The patent has small size of the buckle strip structure, which is beneficial to maximize the exposed area of the assembly, that is, to maximize the power generation efficiency per unit area; because of the small size and simple structure, the buckle strip structure is easy to process and low in cost; because of the simple structure, the buckle strip structure can provide sufficient protection without using too thick wall thickness; and because of the thin wall thickness, the sealing performance of the transverse rubber strip is not affected.

[0033] 4. The patent uses or assists to use a metal hook to fix, and the wind lifting resistance can be increased. BRIEF DESCRIPTION OF DRAWINGS

The first horizontal U-shaped strip 2.2 is connected to the left or right end of the photovoltaic module 1, and the second horizontal U-shaped strip 3.2 is connected to the right or left end of the photovoltaic module 1. The first vertical U-shaped strip 2.1 and the second vertical U-shaped strip 3.1 face opposite directions, and the first vertical U-shaped strip 2.1 can be engaged and spliced ​​with the second vertical U-shaped strip 3.1.

[0047] Specifically, the first horizontal U-shaped strip 2.2 or the second horizontal U-shaped strip 3.2 forms a sealing cavity I, which is filled with sealant. The photovoltaic module 1 is pressed into the first horizontal U-shaped strip 2.2 or the second horizontal U-shaped strip 3.2, and the photovoltaic module 1 is connected to the sealing cavity I through the sealant. The side wall of the sealing cavity I is provided with a guide groove I.1, and the bottom of the sealing cavity I is provided with a blocking groove I.2. The guide groove I.1 and the blocking groove I.2 serve as guides and blocks for sealant overflow, facilitating the even distribution and filling of the sealant, ensuring the thickness of the sealant, and giving it sufficient strength.

The longitudinal strip 4 is compressed by the connecting walls of the first vertical U-shaped strip 2.1 and the second vertical U-shaped strip 3.1. The deformation of the longitudinal strip 4 generates a rebound force. The rebound force expands the groove strip 2 and the buckle strip 3, so that the first protruding strip 2.11 and the first groove 3.12, and the second protruding strip 3.11 and the second groove 2.12 are subjected to force to form a self-locking. The buckle strip 3 is moved horizontally to separate the protruding strip and the groove, thereby disengaging the self-locking.
