UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a photovoltaic support component, which is firm, durable and stable.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows:

[0013] The bottom surface of the base of the support leg is provided with a pair of guide blocks arranged in parallel.

[0014] The support leg can produce a support component with complex shape and various structures. Through the die casting process, the main stress part of the photovoltaic support leg can be designed with fine structure reinforcement, such as skillfully increasing the reinforcing ribs, flexibly adjusting the wall thickness, and skillfully setting the limiting plate at the bottom, so as to ensure that the support component will not slide in the vertical direction of the track, and the carrying capacity and stability of the support component are significantly improved. In addition, the support leg also has the advantages of high precision, difficult deformation of finished products, high yield and the like, so that it can better adapt to various complex application scenarios and different load requirements. At the same time, the bolt fastener also successfully solves the problem that the traditional fastening assembly is easy to slide along the vertical track direction when facing the impact of waves.

[0018] 2. Each support leg is cleverly equipped with a limiting device (guide block) at the bottom, which effectively prevents lateral displacement of the structure when under stress, ensuring the stability of the entire system.

[0019] 3. The support legs have undergone precise structural design, and the main stress areas, such as the upper and lower parts of the support, have been widened and thickened to strengthen them. Compared with traditional compression support legs, their overall compressive strength has been significantly improved, making them more robust and durable.

[0020] 4. Side plates were added to the hollowed-out area of ​​the support leg, and the bottom area of ​​the support leg at the rear end was widened. These improvements work together to greatly enhance the torsional resistance of the entire structure, enabling it to remain stable in complex environments.

[0021] 5. The support legs have pre-drilled holes on the base during the mold-making stage, eliminating the need for secondary machining and reducing secondary processing costs. Furthermore, the support legs can be marked during the die-casting stage, effectively preventing material mixing issues during shipment and improving management efficiency.
