Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation structures, and particularly relates to a photovoltaic panel frame for enhancing structural strength. Background Technique

[0002] A photovoltaic panel mainly consists of a junction box, a backboard, solar cells, an EVA film, glass, and an aluminum alloy frame. The aluminum alloy frame is the so-called photovoltaic panel frame. This frame mainly fixes and installs the backboard, solar cells, EVA film, and glass together, and then fixes them to a photovoltaic bracket. At present, there are various ways to assemble the photovoltaic panel frame. Some are fixed by screws. Although this method is reliable, the assembly of multiple screws is very troublesome. After traditional simplification, it is clamped through an L-shaped connector. Although this simplifies the process, the clamping is not stable enough and is prone to looseness. Therefore, we propose a photovoltaic panel frame for enhancing structural strength. Content of the Utility Model

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0018] As Figures 1-3 shown, a photovoltaic panel frame for enhancing structural strength includes an L-shaped insert 6, a first frame body 1 and a second frame body 2. A first connecting structure 4 is fixedly installed on the lower surface of the first frame body 1. Insertion holes 5 are opened at both ends of the first frame body 1 and the second frame body 2 respectively. A second connecting structure 3 is fixedly installed on the lower surface of the second frame body 2. After the L-shaped insert 6 is inserted into the insertion hole 5, the L-shaped insert 6 will have a frictional force on the inner surface of the insertion hole 5, and this force prevents the L-shaped insert 6 from detaching from the insertion hole 5;

[0019] The first frame body 1 includes a first wide frame 101, a first long frame 102, a first hinge 103 and a first screw hole 104. The first wide frame 101 is movably connected to the first long frame 102 through the first hinge 103. A first screw hole 104 is provided on the surface of the first wide frame 101. The second frame body 2 includes a second wide frame 201, a second long frame 202, a second hinge 203 and a second screw hole 204. The second wide frame 201 is movably installed on the second long frame 202 through the second hinge 203. A second screw hole 204 is provided on the lower surface of the second wide frame 201. The first connection structure 4 includes a first connection bar 401, a first rotating shaft 402, a first bolt 403 and a lock hole screw hole 404. The first rotating shaft 402 is fixed on the first long frame 102. The first connection bar 401 is movably connected to the first long frame 102 through the first rotating shaft 402 near one end. A first bolt 403 is movably inserted through the first connection bar 401 near the other end. A lock hole screw hole 404 is provided in the middle of the first connection bar 401. The second connection structure 3 includes a second connection bar 301, a second rotating shaft 302, a locking connection bar 304, a second bolt 303, an oblong hole 305, a third rotating shaft 306 and a third bolt 307. The second connection bar 301 is movably installed on the lower surface of the second long frame 202 through the second rotating shaft 302 near one end. A second bolt 303 is movably inserted through the other end of the surface of the second connection bar 301. A third rotating shaft 306 is fixedly installed in the middle of the second connection bar 301. An oblong hole 305 is provided near one end of the surface of the locking connection bar 304. The locking connection bar 304 is movably installed on the surface of the third rotating shaft 306 through the oblong hole 305. A third bolt 307 is inserted through the other end of the surface of the locking connection bar 304. The locking connection bar 304 can slide on the surface of the second connection bar 301 through the oblong hole 305 and the third rotating shaft 306, so that the space occupied is reduced during folding. The third bolt 307 is matched with the lock hole screw hole 404, the first bolt 403 is matched with the first screw hole 104, and the second bolt 303 is matched with the second screw hole 204. The insertion holes 5 are opened at the two ends of the first long frame 102 and the first wide frame 101 that are not connected to the second wide frame 201 and the second long frame 202. There are two L-shaped inserts 6, and the insertion holes 5 are matched with the L-shaped inserts 6.

[0020] It should be noted that the present utility model is a photovoltaic panel frame for enhancing structural strength. During installation, the first frame body 1 and the second frame body 2 are each rotated 270 degrees from the folded state, so that the first long side frame 102 and the first wide side frame 101 are perpendicular, and the second wide side frame 201 and the second long side frame 202 are perpendicular. Then, one end of the first connecting bar 401 is fixed to the first wide side frame 101 by screwing the first bolt 403 into the first screw hole 104. In this way, the part formed by connecting the first wide side frame 101, the first long side frame 102 and the first connecting bar 401 forms a stable triangular structure. Similarly, the second connecting bar 301 can be fixed to the second frame body 2 by screwing it into the second screw hole 204 through the second rotating shaft 302. The second wide side frame 201, the second long side frame 202 and the second connecting bar 301 form a stable triangular structure. After connection, other structures of the photovoltaic panel can be inserted and installed into the frame composed of the first frame body 1 and the second frame body 2. Then, the L-shaped plug-in member 6 is inserted into the plug-in holes 5 at the corresponding ends of the first frame body 1 and the second frame body 2 for docking. After docking, the third bolt 307 is screwed into the locking hole screw hole 404 to fix the locking connecting bar 304 on the first connecting bar 401. In this way, the first frame body 1 and the second frame body 2 can be connected and locked, so that the connection points of the first frame body 1 and the second frame body 2 are tightened and will not loosen. Therefore, the tightness of its connection and installation is enhanced, and the installation is more simple.
