Description

Fastening structure of solar panel fixing frame

The present invention is related to the structure of a fixed frame, and particularly refers to a fixed frame of a solar power generation panel.

As shown in Figure 4, when assembling the solar power panel 6, the upper fixing frame 81 must be fastened to the lower fixing frame 82 with bolts 71, so that the upper and lower fixing frames 81 and 82 firmly clamp the solar power panel 6. The conventional bolt 71 is matched with the nut 72. After the bolt 71 abuts on the upper fixing frame 81 and passes through the upper and lower fixing frames 81 and 82, the nut 72 is pressed upwards against the lower fixing frame 82 to achieve The purpose of fixing solar power panels 6. However, the solar power panel 6 and its upper and lower fixing frames 81, 82 are installed outdoors, which will produce slight vibration under the wind and rain. If this happens, the locked nut 72 will still loosen, resulting in the solar power panel 6 It cannot be stabilized, and will hit the upper and lower fixing frames 81 and 82 under vibration to cause damage.

In view of this, how to improve the above-mentioned problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide a solar panel fixing frame fastening structure, which can firmly combine the bottom frame and the upper fixing frame to prevent vibration from falling off.

In order to achieve the foregoing objective, the present invention provides a solar panel fixing frame fastening structure, which includes: a long strip of bottom frame with a top plate, the top plate is provided with an opening, the edge of the opening is connected in one direction The ring wall extending downward, the ring wall is provided with an internal thread section; the two sides of the top plate are respectively connected with a first vertical section extending downward, the first vertical section is connected with a horizontally extending horizontal section, and the horizontal section is connected A second upright section extending downwards, and the second upright section is connected to a bottom plate; a fixing frame located above the bottom frame, which has a base plate, the base plate is provided with a hole corresponding to the opening, the base plate A wing plate extends from both sides of the wing plate, and an assembly space for solar panels is formed between the wing plate and the cross section; a bolt has a head and a body, and the head abuts against the base plate, And the body passes downward through the perforation and the opening and is screwed to the internal thread section of the ring wall; a nut is screwed on the bolt, and the top surface of the nut is provided with a Jacket of the ring wall.

In one embodiment, a groove for drainage and ventilation is provided at the junction of the horizontal connecting section and the first straight section.

In one embodiment, a waterproof and insulating rubber strip is provided on the wing plate and the cross section to separate the solar panels.

The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description of the following selected embodiments and the accompanying drawings.

Figure 1 is a three-dimensional exploded schematic diagram of the present invention; Figure 2 is a schematic cross-sectional view of the present invention; Figure 3 is a schematic cross-sectional view of a partial structure of the present invention; Figure 4 is a schematic view of the conventional structure in use.

Please refer to FIGS. 1 and 2, the fastening structure of the solar panel fixing frame provided by the present invention includes a long bottom frame 1, an upper fixing frame 2, a bolt 3 and a nut 4.

The bottom frame 1 has a top plate 11, the top plate 11 is respectively provided with a downwardly extending first straight section 12 on both sides of the long side, and the bottom end of the first straight section 12 is connected to a horizontally extending cross section 13. The cross section 13 is connected to a second vertical section 14 extending downward, and the second vertical section 14 is connected to a bottom plate 15. The bottom plate 15 is provided with a fixing hole 151, which can be locked on the ground or the roof through screws 152.

In this embodiment, the connection between the horizontal connecting section 13 and the first straight section 12 is provided with a recessed long groove 16 which can be used for drainage and ventilation.

The upper fixing frame 2 has a base plate 21 located on the top plate 11 of the base frame 1. A wing plate 22 extends from both sides of the base plate 21, and a wing plate 22 is formed between the wing plate 22 and the cross section 13 for installation. The assembly space of the solar panel 5. A waterproof insulating rubber strip 51 is provided on the wing board 22 and the transverse section 13 to separate the solar panel 5.

The top plate 11 of the bottom frame 1 is provided with an opening 111, the edge of the opening 111 is connected to a downwardly extending ring wall 112, and the ring wall 112 is provided with an internal threaded section 113. The base plate 21 of the upper fixing frame 2 is provided with a through hole 211 corresponding to the opening 111. On the other hand, the bolt 3 has a head 31 and a threaded body 32, and the bolt 3 has the body 32 downward Pass through the perforation 211 and the opening 111, use the head 31 to abut the base plate 21 for positioning, and use the body 32 to screw on the internal thread section 113 of the ring wall 112 to lock the base frame 1 accordingly With the upper fixing frame 2.

Furthermore, the present invention uses the nut 4 to strengthen and lock the bottom frame 1 and the upper fixing frame 2. In detail, the nut 4 protrudes from the top surface 41 of a jacket 42 that forms a ring shape and surrounds the screw hole 43. The nut 4 is screwed on the bolt 3 with the screw hole 43, and the ring wall 112 is clamped by the jacket 42 as shown in FIG. 3. As the nut 4 continues to rotate and moves upward along the bolt 3, the jacket 42 will force the ring wall 112 to be more tightly pressed against the bolt 3, thereby tightening the nut 4 on the bolt 3. Will not fall off due to vibration.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent elements should still belong to the scope of the present invention.

In summary, those skilled in the art can understand that this invention can clearly achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, so it is necessary to file an application in accordance with the law.
