[0040] In the description of the present invention, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. The orientation or position relationship indicated by the terms "portion", "side", "end", etc. is based on the orientation or position relationship shown in the drawings and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0041] like Figure 1 As shown, the present application provides a portable photovoltaic bracket, including a base frame 1 and a telescopic mechanism 2, one end of the base frame 1 is rotatably provided with a second fastener 5, the other end is rotatably provided with the telescopic mechanism 2, and the other end of the telescopic mechanism 2 is rotatably provided with a first fastener 4; the first fastener 4 and the second fastener 5 are used to respectively fasten the two ends of the same photovoltaic panel 600.

[0042] In a specific embodiment, the bottom frame 1 is a rectangular frame structure, which serves as the base of the photovoltaic bracket. When the photovoltaic panel 600 is installed, the lower end of the photovoltaic panel 600 is buckled with the second fastener 5, and the upper end is buckled with the first fastener 4. By adjusting the length of the telescopic mechanism 2, the angle of the photovoltaic panel 600 is adjusted to make the photovoltaic panel 600 work at the best angle. Preferably, the size of the photovoltaic panel 600 is consistent with the size of the rectangular frame structure of the bottom frame 1, ensuring that the angle between the telescopic mechanism 2 and the bottom frame 1 is less than 90° when the bracket is in use, which can provide good stability.

[0043] like Figure 1-Figure 4 As shown, the telescopic mechanism 2 includes an outer support rod 21, an inner support rod 22, an embedded part 23 and a locking part 24; the inner support rod 22 is provided with an embedded groove 221 along the length direction, and the embedded part 23 is slidably arranged in the embedded groove 221; one end of the inner support rod 22 is slidably inserted into the outer support rod 21, and the locking part 24 passes through the outer support rod 21 and is threadedly connected to the embedded part 23, and the embedded part 23, the outer support rod 21 and the inner support rod 22 are locked to each other by tightening the locking part 24.

[0044] In a specific embodiment, the outer support rod 21 is rotatably arranged at one end of the bottom frame 1, and the first fastener 4 is rotatably arranged at one end of the inner support rod 22 away from the outer support rod 21, and the locking member 24 is a butterfly bolt, and the embedded member 23 is provided with at least one matching threaded hole, and one end of the outer support rod 21 is provided with a through hole matching the butterfly bolt. During installation, the butterfly bolt passes through the through hole at the end of the outer support rod 21 and is threadedly connected with the embedded member 23, and the embedded member 23 is inserted from the bottom of the embedded groove 221, and the butterfly bolt is tightened after sliding to a suitable position, so that the outer support rod 21 and the embedded member 23 clamp the outer wall of the inner support rod 22 to achieve fixation. Through the above structure, the bracket can achieve stepless adjustment of the opening and closing angle within a certain range and fixation, and the structure is simple and easy to operate.

[0045] Further, combined with Figure 8 It can be seen that the outer support rod 21 and the inner support rod 22 can be separated and stored between the photovoltaic panel 600 and the bottom frame 1, and the embedded parts 23 are connected to the outer support rod 21 through the locking parts 24 and stored together. More specifically, after the outer support rod 21 and the inner support rod 22 are separated from each other, the outer support rod 21 is connected to the bottom frame 1, and the inner support rod 22 is connected to the photovoltaic panel 600, and the photovoltaic panel 600 and the bottom frame 1 are brought closer to each other until the back of the photovoltaic panel 600 is in contact with the bottom frame 1, and the outer support rod 21 and the inner support rod 22 are stored between the photovoltaic panel 600 and the bottom frame 1, so that the bracket is closed and easy to carry and transport.

Two longitudinal beams 14 are also fixedly connected between the front beam 12 and the rear beam 13. The two longitudinal beams 14 are arranged between the two main beams 11 to further improve the stability of the bottom frame 1. Furthermore, two first connecting ears 121 are arranged at the rear side of the front beam 12 to respectively hinge the outer support rods 21 of the two telescopic mechanisms 2, and the rear beam 13 is rotatably provided with two second fasteners 5.

The ballast plate 3 is fixedly connected to the upper end of the longitudinal beam 14, and the middle part and two side wings are bent downward and flush with the ground. More specifically, the two longitudinal beams 14 are arranged on the inner side of the two telescopic mechanisms 2.

The upper end of the inner support rod 22 is provided with a rubber pad for abutting and supporting the photovoltaic panel 600. Through the above structure, after the bracket is closed, the bottom frame 1, the telescopic mechanism 2, and the photovoltaic panel 600 are relatively fixed to avoid shaking during transportation and increase the stability of the overall structure.

[0052] In a specific embodiment, a through hole is provided at the end of the first crank arm 42, which is hinged to the inner support rod 22 by a hinge such as a bolt or a pivot. The first hook 41 is a hook-shaped structure bent twice at 90 degrees, connected to the upper end of the photovoltaic panel 600, and fixedly connected to the photovoltaic panel 600 by a bolt at the front end of the first bend.

Through this structure, the photovoltaic panel 600 is more stable when closed.

A circular groove 131 is provided on the rear beam 13, and a circular buckle 521 matching the circular groove 131 is provided at the end of the third arm 52, and the circular buckle 521 is rotatably buckled with the circular groove 131.
