Detailed Description

As shown in fig. 1-2, this embodiment is a photovoltaic support, which performs positioning treatment on a photovoltaic module on a color steel tile, where the photovoltaic support is configured as follows: the locking part 2 and the supporting part 3 forming the locking structure are arranged on the upstream side and the downstream side of the side surface of the photovoltaic module, the connecting part (not shown in the figure) passes through the locking part 2 in the direction X and is inserted into the supporting part 3, the photovoltaic module on the supporting part 3 is pressed to form a locking state, the clamping part is arranged below the supporting part and is used for clamping the purline 1 on the color steel tile, wherein the supporting part 3 is hollow, and is provided with a positioning member 5 inclined relative to the connecting part, and the through hole 9 (not shown in the figure) on the positioning member 5 is formed by penetrating the connecting part in a wedge-shaped inclination mode.

It is known that the locking mode utilizes wedge-shaped inclination to promote expansion to generate larger friction force, so that a stronger locking effect is obtained, and for the vertical assembly mode in the prior art, the locking mode not only maintains the fixing performance of the original via hole, but also can increase the expansion mode to change the volume of the connecting part, increase the contact area and the friction force, thereby avoiding inconsistent abrasion degree in the prior art and solving the problem of loosening or shaking of the photovoltaic panel.

That is, the photovoltaic module is fixed in a clamped manner, and is positioned by a gap between the locking portion 2 located above the photovoltaic module and the supporting portion 3 located below the photovoltaic module.

The inclination of the via hole 9 can further enhance the suppression of the wobbling of the connection portion.

Therefore, in the elongated state of the mating support portion 3, a stronger bending resistance effect is provided when facing the windward direction.

In the embodiment, the locking part 2 and the supporting part 3 are arranged in a posture of being connected with each other through the connecting part, the locking part 2 is rectangular, the wing part 4 is arranged at the upper edge of the locking part 2, and after the locking part 2 is installed on the supporting surface through the connecting part, a locking area for pressing the photovoltaic module is formed in the area between the wing part 4 and the supporting surface.

In this embodiment, the connection portion may be one of a self-tapping screw and a connecting screw, and the above is merely illustrative, and is not a further limitation of the connection portion, and the kind of the connection portion may be further selected according to the actual situation.

The direction X is from top to bottom, and the self-tapping screw sequentially passes through the locking portion 2, the supporting portion 3, and the supporting member 5 in the supporting portion 3, and the via hole 9 is formed by the supporting member 5 being passed through by the self-tapping screw. In the support part 3, the positioning members 5 are provided in plurality, the positioning members 5 are installed in the support part 3 in a cross connection mode, in the embodiment, the positioning members 5 are provided with 8 positioning members 5, and the positioning members 5 are in a net-shaped structure, so that the axial force is guided to the whole support part 3 for increasing the transmission route of the axial force, and the stability of the connecting part in the support part is enhanced.
