[0012] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0013] like Figure 1 , Figure 2As shown, a self-tightening device for fixing a solar panel is mainly composed of a bracket 1 and a fixing buckle plate 2. Two brackets 1 are provided, and both ends of a solar panel 8 are respectively placed on the brackets 1, and the top of the solar panel 8 is fixed by the fixing buckle plate 2.
[0014] The bracket 1 is a steel pipe with a square cross-section. Above the bracket 1, one end of the fixing plate 2 away from the solar panel 8 is bent upward to form a fixing portion, and two through holes are respectively provided at both ends of the fixing portion for connection with the U-shaped screw 3.
[0015] The two ends of the U-shaped screw rod 3 are respectively inserted into the through holes on the fixing buckle plate 2 , and then pass through the backing plate 4 under the bracket 1 and are locked by the nut 6 .
[0016] In this embodiment, Figure 6 As shown, a mounting groove 10 is opened in the middle of the pad 4, and a ball 7 is rotatably installed inside the mounting groove 10. The pad 4 is in contact with the surface of the bracket 1 through the ball 7 to form a rolling connection with the bracket 1. The ball 7 is added to the pad 4 to reduce the friction between the pad 4 and the surface of the bracket 1.
[0017] Positioning sleeves 9 are fixedly welded on the upper surface of the backing plate 4 at positions corresponding to the positions connected to the U-shaped screw rod 3. When the U-shaped screw rod 3 passes through the backing plate 4, it also passes through the positioning sleeves 9. The positioning sleeves 9 guide the ends of the U-shaped screw rod 3.
[0018] A hemispherical sleeve 5 is provided between the lower part of the backing plate 4 and the nut 6 corresponding to the end of each U-shaped screw 3, the arc surface of the hemispherical sleeve 5 contacts the lower surface of the backing plate 4, and the bottom of the hemispherical sleeve 5 is fixedly connected to the nut 6.
[0019] When the device is used in a specific application, the following steps are followed: S1. Determine the distance between two adjacent brackets 1 according to the width of the solar panel 8, and then fix the brackets 1.
[0020] S2, then respectively set up the two ends of the solar panel 8 on the two brackets 1 to fix the installation of the gusset plate 2; S3, when fixing the gusset plate 2, Figure 3 As shown, U-shaped screw rods 3 are respectively inserted downwards at both ends of the fixing portion of the fixing buckle plate 2, and the U-shaped screw rods 3 naturally droop due to gravity.
[0021] S4, such as Figure 4 As shown, the end of each U-shaped screw 3 is respectively inserted into the positioning sleeve 9 and passes through the backing plate 4, and the positioning sleeve 9 performs initial adjustment on the U-shaped screw 3.
[0022] S5, such as Figure 5As shown, a nut 6 with a hemispherical sleeve 5 is then installed on each end of the U-shaped screw 3, and as the nut 6 is tightened and squeezed, the hemispherical sleeve 5 and the pad 4 gradually slide upward until the pad 4 no longer moves upward and the U-shaped screw 3 is in a vertical state with the bracket 1, that is, the solar panel 8 is fixed.
[0023] The present invention adds a ball bearing on the pad so that the pad and the bracket can slide relative to each other, reducing the friction between the pad and the bracket and ensuring that the pad can move smoothly; the hemispherical sleeve is a moment fulcrum under imbalance, and the U-shaped screw can be automatically straightened by tightening the nut, and finally the buckle plate can firmly fix the solar panel.
[0024] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
