[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] according to Figures 1 to 6 A welding-free photovoltaic mounting bracket comprises a bottom film 1 and a vertical film 2. The vertical film 2 extends upward from the top of the bottom film 1. The improvement lies in that the bottom film 1 and the vertical film 2 are integrally formed and made of metal material. A plurality of base fixing holes 3 are arranged at the center of the bottom film 1. Two vertical films 2 extend upward from the front and rear sides of the bottom film 1. A plurality of column fixing holes 4 are arranged at the center of the vertical film 2. Buckles 5 extend inwardly from the left and right sides of the upper part of the vertical film 2 to form an installation cavity 6. The cross-sectional shape of the installation cavity 6 matches the cross-sectional shape of the fixed column 9. The fixed column 9 is usually made of profiles, and the cross-section can be rectangular.

[0024] The base fixing hole 3 is preferably a circular hole in the center, with two waist-shaped holes 10 on both sides, and the directions of the two waist-shaped holes 10 are perpendicular to each other. The expansion screw 8 passes through the base fixing hole 3 and is driven into the cement base 7 to fix the bottom film 1 on the top of the cement base 7. The bottom film 1 is fixed on the top of the cement base 7, and the size of the installation cavity 6 matches the size of the fixed column 9, so that the fixed column 9 is inserted into the installation cavity 6. The outer wall of the fixed column 9 is provided with a fixed circular hole, and the corresponding column fixing hole 4 matches it. After the screw passes through the fixed circular hole and the column fixing hole 4, it is screwed in and fixed with the nut, and the fixation is achieved by the screw and nut. The base fixing hole 3 is preferably a circular hole in the center, with two waist-shaped holes 10 on both sides, and the directions of the two waist-shaped holes 10 are perpendicular to each other. The expansion screw 8 passes through the base fixing hole 3 and is driven into the cement base 7 to achieve fixation. The middle and lower part of the vertical piece 2 is a trapezoid, which can increase the metal strength of the left and right vertical pieces 2. The upper part of the vertical piece 2 is a rectangle. When the upper part of the vertical piece 2 is used as a buckle 5, it can limit the activity space of the fixed column 9 to prevent the photovoltaic panel from being damaged due to the sliding of the fixed column 9. The metal material is preferably an aluminum-magnesium-zinc-plated material, which has the advantages of high strength and corrosion resistance, and prevents the connection from reducing the metal strength due to long-term oxidation and corrosion. It is bent into an integral one-piece through a sheet metal process, without the need for welding process, and is fast and convenient.

[0025] When the user uses this product, he first selects a cement base 7 or other solid plane where he plans to set up the photovoltaic panel, then drives the expansion screw 8 through the base fixing hole 3 into the cement base 7 to fix the photovoltaic bracket on the top of the cement base 7, and then inserts the fixed column 9 into the installation cavity 6, passes the screw through the fixed circular hole of the fixed column and the column fixing hole 4, and then screws in the nut to fix it, thereby fixing the fixed column 9 to the photovoltaic bracket.
