Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figures 1 to 3 A photovoltaic aluminum frame that is easy to adjust in size is shown, comprising a frame mounting frame 1 and a corner adjustment frame 2, a connecting rod 3 is fixed at one end of the frame mounting frame 1, the inner cavity of the corner adjustment frame 2 is rotatably connected to two groups of rotating shafts 4 through bearings, a connecting gear 5 is fixed to the surface of the rotating shaft 4, one end of the connecting rod 3 away from the frame mounting frame 1 is fixedly connected to the connecting gear 5, the two groups of connecting gears 5 are meshed with each other, the inner cavity of the corner adjustment frame 2 is provided with an adjusting component 6 for adjusting the angle of the rotating shaft 4, and a limit frame 7 for adjusting the distance between the two groups of corner adjustment frames 2 is clamped on the outer side of the frame mounting frame 1;

[0022] After clamping the same side of the photovoltaic panel with two sets of frame mounting frames 1, adjust the distance between the photovoltaic panel and the corner adjustment frame 2, and then use the limit frame 7 to clamp the two sets of frame mounting frames 1 to connect the frame mounting frames 1, and use the clamping strip 8 and the rack plate 10 to clamp the clamping groove 9 and the tooth groove 11 respectively to limit the movement of the limit frame 7 on the two sets of frame mounting frames 1 to ensure the stability of the aluminum frame. At the same time, photovoltaic panels of different sizes and models can be installed in conjunction with the adjustment component 6, and the structure is stable and not easily affected by external forces.

[0023] The adjustment component 6 includes a worm 61 that rotates in the inner cavity of the edge and corner adjustment frame 2 through a bearing, one end of the worm 61 is rotatably connected to a support block 62 through a bearing, the support block 62 is fixed to the inner cavity of the edge and corner adjustment frame 2, a worm wheel 63 is fixed to the outer side of a set of rotating shafts 4, the worm 61 is meshed with the side facing the worm wheel 63, and the cooperation between the worm 61 and the worm wheel 63 facilitates the driving of the rotating shaft 4, thereby utilizing two sets of meshing connecting gears 5 to drive two adjacent sets of frame installation frames 1 to adjust the angle, and to install the frames of photovoltaic panels of different sizes and shapes.

[0024] The top and bottom of the inner cavity of the limit frame 7 are integrally formed with a clamping strip 8, and a clamping slot 9 is opened on the outer side of the frame mounting frame 1. The clamping strip 8 is clamped in the inner cavity of the clamping slot 9 and is slidably connected with the clamping slot 9. Through the cooperation of the clamping strip 8, the limit frame 7 can be conveniently restricted on the frame mounting frame 1 to prevent the limit frame 7 from falling off the frame mounting frame 1.

[0025] A rack plate 10 is fixed to the side wall of the inner cavity of the limit frame 7, and a tooth groove 11 engaged with the rack plate 10 is opened on the side wall of the frame mounting frame 1. Through the arrangement of the rack plate 10 and the tooth groove 11, it is convenient to limit the limit frame 7 and limit it from different directions with the card strip 8, thereby limiting the stability between the limit frame 7 and the frame mounting frame 1.

[0026] A storage groove 12 is provided on the outer side of the frame mounting frame 1, and the limit frame 7 is located in the inner cavity of the storage groove 12. The width of the frame mounting frame 1 is the same as the width of the limit frame 7.

[0029] During specific use, the protective rubber seat 14 is placed in the groove 13, and then the border mounting frame 1 is clamped on one side of the photovoltaic panel. Subsequently, a tool is inserted into the operating mounting hole 16 to rotate the worm 61. The worm 61 drives a group of rotating shafts 4 to rotate through the worm gear 63, and at the same time, another group of rotating shafts 4 rotate synchronously through the connecting gear 5. The connecting rod 3 is used to drive the border mounting frame 1 connected to the corner adjustment frame 2 to adjust the angle, so that another group of border mounting frames 1 are also clamped on the outside of the photovoltaic panel. The same operation is used to clamp multiple groups of border mounting frames 1 on the side of the photovoltaic panel, and then the position of the corner adjustment frame 2 is adjusted, and the limit frame 7 is clamped on the outside of the border mounting frame 1. The card strip 8 is clamped with the card slot 9, and the rack plate 10 is clamped with the tooth slot 11 to limit the limit frame 7 to ensure that the limit frame 7 is stably connected to the border mounting frame 1.
