[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0029] Please refer to Figures 1-6 A photovoltaic module frame that is convenient for stacking as shown, including a component frame 1 for connecting a photovoltaic module. The photovoltaic panel is installed on the component frame 1. The component frame 1 is composed of four side strips 101, forming a rectangular or square shape. The photovoltaic module frame of the present invention also includes a link corner fitting 2. Two adjacent side strips 101 are connected by a link corner fitting 2. Generally speaking, the four side strips 101 are connected into an integral photovoltaic module frame through four link corner fittings 2. The side strip 101 is provided with an inner cavity 102 that is convenient for the installation of the link corner fitting 2.

[0030] The connecting corner code 2 is composed of a group of vertically arranged and structurally identical connecting blocks 3. The connecting block 3 includes a head end 301, a tail end 302, barbs 303, and a hollow cavity 304. When the side strip 101 is connected to the connecting corner code 2, the head end 301, the tail end 302, and the barbs 303 provided on the connecting block 3 are all installed in the inner wall 102 provided on the side strip 101. A plurality of barbs 303 are evenly arranged on both side surfaces of the head end 301, and the hollow cavity 304 is arranged at one end close to the head end 301. The head end 301, the tail end 302, and the barbs 303 are of an integrally formed structure. The distance between the end faces of the barbs 303 provided on the side surface of the head end 301 is greater than the distance between the upper and lower cavity surfaces of the inner cavity 102. When the connecting corner code 2 is connected to the side strip 101, the barbs 303 contact the inner side surface of the inner cavity 102, and a frictional force and a squeezing force are generated between the two, so that the connecting corner code 2 and the side strip 101 are firmly connected.

[0031] At the same time, threaded holes 4 are provided on both the side strip 101 and the connecting block 3. The threaded holes 4 penetrate through the side strip 101 and the connecting block 3 at the same time. When the side strip 101 and the connecting block 3 are connected, they are further tightly connected by countersunk head screws. After the side strip 101 is connected by the connecting corner code 2, the side strip 101 and the connecting corner code 2 are further tightly connected by countersunk head screws, further increasing the rigidity after their connection and ensuring the rigidity and stability of the entire device.

[0032] In order to prevent damage when the photovoltaic module frames are stacked, a first boss 305 is provided on the connecting block 3, and a semi-cylindrical arc groove 306 is provided on the first boss 305. A second boss 307 is provided on the side surface far from the first boss 305, and a semi-cylindrical boss 308 that cooperates with the arc groove 306 is fixedly provided on the second boss 307. The distance between the upper end face of the first boss 305 and the lower end face of the second boss 307 is greater than the thickness of the side strip 101. The distance between the end faces of the barbs 303 provided on the side surface of the head end 301 is greater than the distance between the upper and lower cavity surfaces of the inner cavity 102. Specifically, when stacking, the semi-cylindrical boss 308 on the second boss 307 falls into the arc groove 306 on the first boss 305. Because the distance between the end faces of the barbs 303 provided on the side surface of the head end 301 is greater than the distance between the upper and lower cavity surfaces of the inner cavity 102, there is a gap between the side strip 101 bodies of the two frames after stacking, avoiding friction and thus preventing damage caused by scratching.

[0033] Specifically, a T-shaped installation groove 309 is further provided on the connecting block 3 and an anti-collision strip 310 is provided on the T-shaped installation groove 309. The anti-collision strip 310 is provided with a connecting portion 311 that cooperates with the T-shaped installation groove 309, and an arc chamfer 312 is provided on the side far from the connecting portion 311. The anti-collision strip 310 is made of rubber material.

[0034] In this embodiment, through the design of the anti-collision strip 310, the situation where the corners are damaged due to impact is effectively avoided.

[0035] Specifically, the side strip 101 is provided with a sealing groove 5 designed coaxially with the threaded hole 4, and a sealing plug 6 is provided in the sealing groove 5. The sealing plug 6 is connected to the sealing groove 5 by an interference fit, and the height of the sealing plug 6 is less than the depth of the sealing groove 5.

[0036] In this embodiment, by providing the sealing groove 5 above the threaded hole 4 and providing the sealing plug 6 in the sealing groove 5, it is possible to effectively prevent rainwater and the like from entering the interior of the component through the threaded hole 4, and extend the overall service life of the photovoltaic module frame.
