[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides the following technical solution:

[0020] Example 1: A photovoltaic grid-connected cabinet that is easy to maintain includes a rear panel 1, a top panel 2 and a bottom panel 3 respectively installed on the top and bottom of the rear panel 1, two side panels 4 located between the top panel 2 and the bottom panel 3, and a cover plate 5 hinged to the side panels 4 for closing the cabinet. A handle 51 is fixedly connected to the outer wall of the cover plate 5, and the handle 51 is set on the wall of one end of the side panel 4.

[0021] The main body of the photovoltaic grid-connected cabinet consists of a rear panel 1, a top panel 2, a bottom panel 3, and two side panels 4. A cover 5 for opening and closing is hinged at the opening. The cover 5 can be rotated by a handle 51 when opening and closing.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes two-section locking grooves 6 and limiting arc grooves 7 on both the bottom of the top plate 2 and the top of the bottom plate 3;

[0023] The side plate 4 includes a connecting plate 41 and an adjusting plate 42. The connecting plate 41 and the adjusting plate 42 are slidably connected. The connecting plate 41 is hinged to the top plate 2 and the bottom plate 3 by a pin. A through groove 422 is provided on the outer wall of the connection between the adjusting plate 42 and the connecting plate 41. A connecting bolt 423 is movably inserted into the through groove 422. One end of the connecting bolt 423 passes through the through groove 422 and is connected to the connecting plate 41. Locking pins 424 are fixedly connected to the top and bottom of the end of the adjusting plate 42 away from the connecting plate 41. The locking pins 424 are slidably inserted into the interior of the two-section locking groove 6.

[0024] Limiting posts 52 are fixedly connected to the top and bottom of the cover plate 5, and the limiting posts 52 are inserted into the interior of the limiting arc groove 7;

[0025] A stroke slider 421 is fixedly connected at the connection between the adjusting plate 42 and the connecting plate 41. A stroke groove 411 is provided on the plate wall of the connecting plate 41 corresponding to the stroke slider 421, and the stroke slider 421 is slidably connected inside the stroke groove 411.

[0026] The two-section locking groove 6 includes a straight groove and an arc-shaped groove, and the two grooves are connected. The center of the arc-shaped groove is on the same axis as the axis of the pin on the connecting plate 41.

[0027] The center of the limiting arc groove 7 and the axis of the pin on the cover plate 5 are on the same axis.

[0028] In use, the cover plate 5 can be flipped by the handle 51, and when the cover plate 5 rotates around its own pin, it can drive the limiting post 52 to slide along the limiting arc groove 7.

[0029] When the cover plate 5 is flipped open, and it is found during the inspection of the inside of the photovoltaic grid-connected cabinet that the space opened by the two cover plates 5 is insufficient, the adjusting plate 42 can be pulled outward, so that the adjusting plate 42 drives the locking column 424 and the travel slider 421 to move synchronously. The locking column 424 can move along the straight groove inside the two-section locking groove 6, while the travel slider 421 slides along the travel groove 411. When the travel slider 421 moves to the end inside the travel groove 411, the locking column 424 can move into the arc-shaped groove inside the two-section locking groove 6. At this time, the connecting plate 41 can flip outward with its own pin as the axis. When the connecting plate 41 flips, it can drive the adjusting plate 42 and the cover plate 5 to rotate synchronously. When the adjusting plate 42 rotates, it can drive the locking column 424 to move and slide out along the arc-shaped groove inside the two-section locking groove 6, so that the side plate 4 can be opened together with the cover plate 5, so that the internal structure of the photovoltaic grid-connected cabinet is completely exposed, thereby increasing the area that can be inspected and making the inspection more convenient.

[0030] When the cover plate 5 is not flipped, the limiting post 52 is located inside the limiting arc groove 7. If the adjusting plate 42 drives the locking post 424 to move along the straight groove on the two-section locking groove 6, the locking post 424 can be prevented from moving because the limiting post 52 and the arc inner wall of the limiting arc groove 7 are in contact. This can effectively prevent the adjusting plate 42 from moving accidentally.

[0031] Example 3: The technical solution of this example, which differs from that of Example 2, includes a mounting bracket 11 installed on the wall of the rear plate 1. The mounting bracket 11 includes a mounting plate with a mounting groove and a mounting rod.

[0032] The mounting rod can be used to connect the mounting plate to the rear plate 1, while the mounting plate with mounting slots can be used to install equipment inside the grid-connected cabinet.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
