[0029] Please refer to Figures 1-6 A kind of photovoltaic module frame that can be quickly assembled as shown, which includes a component frame 1 for connecting a photovoltaic module and a connecting piece 2. The component frame 1 is composed of four side strips 101. Two adjacent side strips 101 are connected by the connecting piece 2. Finally, the four side strips 101 are assembled into a rectangular or square component frame 1 through the connection of four connecting pieces 2.

[0030] Both ends of the side strip 101 are designed with symmetric 45-degree oblique angles, and the side strip 101 is provided with an inner cavity 103 and a stabilizing strip 102 arranged on the inner cavity 103. The stabilizing strip 102 and the side strip 101 are of an integrally formed structure;

[0031] The connecting member 2 is composed of a group of vertically arranged and structurally identical engaging components 3. The engaging component 3 includes a head end 301, a tail end 302, a supporting portion 303, and barbs 304. The cross-section of the head end 301 is in a trapezoid-like structure, and an arc chamfer 309 is provided on the side of the head end 301 to facilitate the penetration of the head end 301 into the inner cavity 103.

[0032] The supporting portion 303 is arranged between the head end 301 and the tail end 302. The barbs 304 are arranged on the supporting portion 303, and a plurality of barbs 304 are evenly arranged on both side surfaces of the supporting portion 303. When the head end 301 penetrates into the inner cavity 103, the barbs 304 arranged on the supporting portion 303 also enter the inner cavity 103 accordingly. The distance between the end faces of the barbs 304 arranged on both side surfaces of the supporting portion 303 is greater than the height of the inner cavity 103, so that frictional force is generated between the barbs 304 and the surface of the inner cavity 103, making the connection firm. At the same time, a reinforcing portion 305 is provided at the bottom of the barb 304, and the reinforcing portion 305 is fixedly connected to both the barb 304 and the supporting portion 303. Through the setting of the reinforcing portion 305, the strength of the tail end of the barb 304 is improved, and the risk of the barb 304 breaking from its bottom is reduced.

[0033] A groove 306 matching with the stabilizing strip 102 is provided on the tail end 302, and the groove 306 extends to the barb 304 and the head end 301. When the side strip 101 is connected to the engaging portion 3, the stabilizing strip - groove 306 is connected by an interference fit method, which improves the overall torsional resistance after connection.

[0034] Specifically, there are two groups of stabilizing strips 102, and one group is provided on each of the upper and lower cavity surfaces of the inner cavity 103. There are also two groups of grooves 306, which respectively match with the two groups of stabilizing strips 102.

[0035] In this embodiment, through the setting of the two groups of stabilizing strips 102 and the cooperation with the two groups of grooves 306, the torsional resistance is further ensured.

[0036] Specifically, a first hollow hole 307 is provided on the head end 301, and a second hollow hole 308 is provided on the tail end 302.

[0037] In this embodiment, the designed first hollow hole 307 and second hollow hole 308 are for reducing the overall weight of the connecting member 2, which is a lightweight design.

[0038] Working principle: When assembling, first prepare two side strips 101 and a connecting piece 2. Then align the end 301 with the inner cavity 103, and press the engaging part 3 into the inner cavity 103 by applying force or with the aid of auxiliary tools. After pressing, the end of the barb 304 contacts the surface of the inner cavity 103, and the two side strips 101 are connected through the frictional force and extrusion force between them. At the same time, the stabilizing strip 102 and the groove 306 are fitted through an interference fit method, further strengthening the connection strength between the connecting piece 2 and the side strip 101, and at the same time providing a certain torsional resistance.
