[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Such as Figures 1-5As shown in the figure, a quickly foldable photovoltaic panel bracket includes a fixed column 1 and a movable column 11. During actual use, the fixed column 1 is first fixed in position, while the movable column 11 is slidably connected to the installation position, and two fixed crossbars 7 connected between the two. The middle parts of the two fixed crossbars 7 are rotatably connected, and one end of each of the two fixed crossbars 7 is rotatably installed at the bottom edges of the opposite faces of the fixed column 1 and the movable column 11, and the other ends are respectively inserted into the opposite sides of the movable column 11 and the fixed column 1. The two fixed crossbars 7 are cross-connected to fix the fixed column 1 and the movable column 11. By changing the angle between the two fixed crossbars 7, the distance between the fixed column 1 and the movable column 11 is controlled. Guide grooves 9 into which the other ends of the fixed crossbars 7 are inserted are provided on the opposite faces of the fixed column 1 and the movable column 11. A lead screw 12 with a thread passing through the other end of the fixed crossbar 7 is rotatably connected to the inside of one side of the fixed column 1. A bevel gear ring 14 is fixedly connected to the bottom edge of the lead screw 12. A bevel gear 15 meshing with the bevel gear ring 14 is rotatably connected to the inside of the fixed column 1, and a handle 3 connected to the end face of the bevel gear 15 is rotatably connected through the fixed column 1. By rotating the handle 3, the corresponding installed bevel gear 15 can be rotated. Under the meshing connection, the bevel gear ring 14 drives the lead screw 12 to rotate, and then the top end of one of the fixed crossbars 7 threadedly connected to the lead screw 12 is lifted. As Figure 1 shown in the figure, by using the lifting of the top end of the fixed crossbar 7 to adjust the relative distance from the bottom end of the other fixed crossbar 7, the angle between the two fixed crossbars 7 is adjusted. Then, without changing the position of the fixed column 1, the movable column 11 is pushed to slide. A spur gear 16 is rotatably connected to the inside of the bottom end of the movable column 11, and two racks 10 meshing with the spur gear 16 are inserted. The tooth surfaces of the two racks 10 face each other and are vertically offset. A non-slip plate 13 is fixedly connected to the bottom end of one of the racks 10, and a roller 8 is fixedly connected to the bottom end of the other rack 10. By rotating the spur gear 16, the two meshing racks 10 move one up and one down, that is, the rack 10 installed with the roller 8 descends to contact the ground, and the roller 8 can be used to smoothly move the movable column 11. When the rack 10 installed with the non-slip plate 13 descends until the non-slip plate 13 contacts the ground, the position of the bottom edge of the movable column 11 can be fixed.

[0025] In addition, the non-slip plate 13 fixed to the bottom ends of the two racks 10 and the top and side edges of the roller 8 are inserted into the bottom end of the movable column 11, ensuring that the two racks 10 can only move up and down under the rotation of the spur gear 16.

[0026] In addition: Longitudinally arranged sliding grooves 2 are provided at the same side positions of the fixed column 1 and the movable column 11. A folding plate 5 is rotatably connected to the bottom of the sliding groove 2. The top edge of the folding plate 5 is rotatably connected to an inclined pull arm 4. One end of the inclined pull arm 4 is inserted into the sliding groove 2 and a bolt 6 is connected between the inclined pull arm 4 and the side wall of the sliding groove 2. By connecting the inclined pull arm 4 to different positions on the side wall of the sliding groove 2 with the bolt 6, it is convenient to adjust the angle of the folding plate 5 so as to cope with the installation on the ground with different inclination angles. The side wall of the sliding groove 2 is provided with a hollow, and the bolt 6 penetrates through the hollow; an anti-slip plate 13 is also embedded at the bottom edge of the folding plate 5 installed on the movable column 11, a bolt 6 is also threadedly connected at the top edge position, and the bottom end of the bolt 6 on the folding plate 5 is rotatably connected to the top edge of the anti-slip plate 13. By rotating the bolt 6 on the folding plate 5, the anti-slip plate 13 can be lowered to contact the ground, that is, to ensure the fixation of the position of the bottom edge of the folding plate 5 on the movable column 11; one end of the spur gear 16 extends outwards and is also fixedly connected to a handle 3, and the handle 3 on the end face of the spur gear 16 penetrates through the side of the movable column 11, which is convenient to rotate the spur gear 16 by rotating the handle 3. In addition, the handle 3 in this solution can also be selected to use a bolt 6 to fix the relative position with the movable column 11, and then fix the position of the spur gear 16, that is, to ensure that when the roller 8 or the anti-slip plate 13 is in use, it will not rise and fall due to the lifting and lowering of the rack 10, causing the movable column 11 to tilt.

[0027] Working principle: During use, first fix the fixed column 1 to the ground by expansion bolts or other means, and adjust the slope of the folding plate 5 on the fixed column 1 according to the slope of the ground. Similarly, use expansion bolts to fix the position. The movable column 11 rotates the spur gear 16 by rotating the handle 3 on its surface, and then the rack 10 installed with the roller 8 descends to contact the ground. Then use a bolt 6 to lock the relative position of the handle 3 and the movable column 11, and then rotate the handle 3 on the fixed column 1 to drive the bevel gear 15 to drive the bevel gear ring 14 to rotate, and then the lead screw 12 rotates to drive one end of the fixed cross bar 7 connected to it to rise and fall, realizing the angle adjustment of the fixed cross bar 7. With the assistance of the roller 8, the fixed cross bar 7 can easily push the movable column 11 to move. After the distance adjustment is completed, reverse-rotate the handle 3 on the movable column 11 to reverse the spur gear 16, and then the rack 10 installed with the anti-slip plate 13 descends to replace the roller 8 to contact the ground. Lock the relative position of the handle 3 and the movable column 11 again, and use expansion bolts or cement to fix the position of the movable column 11.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
