[0021] A solar photovoltaic junction box adopting a new type of movable compression installation, such as Figure 1 and Figure 2 and Figure 3 , including a photovoltaic panel 1, a junction box body 2 and a frame 3 for installing the photovoltaic panel 1, the rear side of the frame 3 is provided with two slideways 4 distributed up and down, and the two slideways 4 are parallel, and a slide plate 5 is horizontally slidably connected between the two slideways 4, the junction box body 2 is located between the photovoltaic panel 1 and the slide plate 5 and is located in the frame 3, and a clamping mechanism for pressing the junction box body 2 on the photovoltaic panel 1 is provided on the slide plate 5, and a sealing gasket 6 that is pressed against the photovoltaic panel 1 is provided on the side of the junction box body 2 close to the photovoltaic panel 1, and a first limiting member for limiting the sliding of the slide plate 5 on the slide plate 4 is provided on the upper slideway 4.

[0022] like Figure 1 and Figure 2 and Figure 3When in use, install the two slides 4 on the rear side of the frame 3, then place the junction box body 2 at the position where the photovoltaic panel 1 needs to be installed, then connect the photovoltaic panel 1 to the junction box body 2, and then slide the slide plate 5 to the junction box body 2. At this time, the junction box body 2 is located between the slide plate 5 and the photovoltaic panel 1, and then the junction box body 2 is pressed against the photovoltaic panel 1 by the clamping mechanism, so that the sealing gasket 6 is pressed against the photovoltaic panel 1, and then the slide plate 5 is restricted by the first limiting member so that it cannot slide on the slide plate 4. At this time, the junction box body 2 can be installed on the photovoltaic panel 1. The disassembly and assembly are simple and convenient, and there is no need to adhere the junction box body 2 to the photovoltaic panel 1 through silicone, which improves environmental protection.

[0023] like Figure 3 and Figure 4 and Figure 5 The clamping mechanism includes a moving plate 7 and a rectangular groove 8 opened on the side of the slide plate 5 away from the junction box body 2. One end of the moving plate 7 passes horizontally through the rectangular groove 8 and is provided with a pressing plate 9.

The bracket 12 is provided with a pushing member for pushing the moving plate 7 to move toward the photovoltaic panel 1.

[0024] like Figure 3 and Figure 4 and Figure 5 When the junction box body 2 is located between the slide plate 5 and the photovoltaic panel 1, the embedding groove 10 on the pressure plate 9 will correspond to the junction box body 2. At this time, the movable plate 7 is pushed to move toward the photovoltaic panel 1, so that the end of the junction box body 2 away from the photovoltaic panel 1 enters the embedding groove 10 and contacts the bottom of the embedding groove 10. Then, the movable plate 7 is pushed by the pushing member to continue to move toward the photovoltaic panel 1 until the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1. The installation and disassembly are simple.

[0025] like Figure 4The first limiting member includes a plurality of plug holes 13 arranged on the upper slide 4, and each plug hole 13 is spaced apart along the length direction of the slide 4. An inverted L-shaped plug post 14 is provided on the top of the movable plate 7, and the plug post 14 is inserted into one of the plug holes 13 away from the moving level of the movable plate 7. The purpose of this setting is that when the junction box body 2 is located between the slide plate 5 and the photovoltaic panel 1, and the embedding groove 10 on the pressure plate 9 corresponds to the junction box body 2, the plug post 14 will correspond to one of the plug holes 13. When the movable plate 7 moves toward the direction close to the photovoltaic panel 1, the movable plate 7 will drive the plug post 14 to move. When the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1 as the movable plate 7 moves, the end of the plug post 14 away from the movable plate 7 will be inserted into the corresponding plug hole 13. At this time, the cooperation between the plug post 14 and the plug hole 13 can restrict the slide plate 5 from sliding on the slide 4.

[0026] like Figure 5 The pushing member includes a rotating shaft 15 arranged at the top of the bracket 12, and an eccentric wheel 16 is rotatably connected to the rotating shaft 15, one end of the arc surface of the eccentric wheel 16 contacts the side of the moving plate 7 away from the pressure plate 9, and a rotating rod 17 is provided on the end of the eccentric wheel 16 away from the rotating shaft 15. The bracket 12 is provided with a second limiting member for limiting the sliding of the moving plate 7 through the rectangular groove 8. The purpose of this setting is that when it is necessary to push the moving plate 7 to move in the direction close to the photovoltaic panel 1, it is only necessary to drive the eccentric wheel 16 to rotate on the rotating shaft 15 through the rotating rod 17. At this time, the eccentric wheel 16 on the rotating shaft 15 can push the moving plate 7 to move in the direction close to the photovoltaic panel 1. When the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1 as the moving plate 7 moves, the moving plate 7 is restricted by the second limiting member so that it cannot move.

Inserted into the first slot 24, a first push plate 25 is horizontally provided on one side of the first plug plate 23 close to the first connecting groove 20, and the end of the first push plate 25 away from the first plug plate 23 extends horizontally to the first circular groove 21 through the first connecting groove 20, and a first compression spring 26 is provided on the end of the first push plate 25 close to the first placement groove 22, and the end of the first compression spring 26 away from the first push plate 25 is located in the first placement groove 22 and fixedly connected to the bottom groove wall of the first placement groove 22, a first cover plate 27 is provided on the first fixed plate 18, and the first cover plate 27 is used to close the notches of the first vertical groove 19, the first connecting groove 20, the first circular groove 21 and the first placement groove 22, and a first unlocking member is provided on the first fixed plate 18 for pushing the first push plate 25 in the first circular groove 21 to move downward.

[0028] like Figure 3 and Figure 5 and Figure 6 and Figure 7 When the rotating rod 17 drives the eccentric wheel 16 to rotate on the rotating shaft 15, so that the movable plate 7 approaches the junction box body 2 until the sealing gasket 6 on the junction box body 2 is pressed against the photovoltaic panel 1, the first slot 24 on the movable plate 7 will correspond to the first vertical slot 19. At this time, the first compression spring 26 will push the first push plate 25 to move upward, and the first push plate 25 will push the first plug plate 23 to move upward until the top of the first plug plate 23 is inserted into the first slot 24. At this time, the first slot 24 cooperates with the first plug plate 23 and the first vertical slot 19 to restrict the movable plate 7 from moving.

[0029] When the junction box body 2 needs to be replaced, it is only necessary to push the first push plate 25 in the first circular groove 21 downward through the first unlocking piece until the first plug plate 23 is separated from the first slot 24, and then pull the movable plate 7 away from the junction box body 2 until the junction box body 2 is separated from the embedded groove 10 on the pressure plate 9, and then slide the slide plate 5 to be misaligned with the junction box body 2, and then replace the junction box body 2. The disassembly and assembly are simple.

[0030] like Figure 6and Figure 7 The first unlocking member includes a first column 28 and two first baffles 29 arranged on the wall of the first circular groove 21. The two first baffles 29 are opposite to each other up and down, and a first side groove 30 is provided on one side of the first baffle 29 located on the upper side. The first side groove 30 is communicated with the bottom end of the first baffle 29. A first circular hole 31 coaxial with the first circular groove 21 is provided on the first cover plate 27. The first column 28 is horizontal and one end of the first column 28 passes through the first circular hole 31 and contacts with the bottom of the first circular groove 21. A first rotary plate 32 is provided on the side of the first column 28 away from the bottom of the first circular groove 21. A first lever 33 located in the first circular groove 21 is provided on the side of the first column 28 facing away from the first push plate 25, and a first elongated groove 34 communicating with the first circular hole 31 is opened on the first cover plate 27, and the first elongated groove 34 corresponds to the first lever 33. When the first column 28 rotates clockwise, the first lever 33 passes through the first side groove 30, and the first column 28, the first lever 33 and the first rotating plate 32 form a first key 35, and the first elongated groove 34 and the first circular hole 31 form a first lock hole 36 for the first column 28 and the first lever 33 to be inserted into the first circular groove 21.

[0031] like Figure 6 and Figure 7 When it is necessary to push the first push plate 25 in the first circular groove 21 to move downward, it is only necessary to insert the first column 28 in the first key 35 and the first lever 33 into the first circular groove 21 from the first lock hole 36, and then rotate the first key 35 clockwise so that the first lever 33 contacts the top of the first push plate 25 after passing through the first side groove 30, and then continue to rotate the first key 35 clockwise. At this time, the first lever 33 will push the first push plate 25 to move downward. Through the cooperation of the first key 35 and the first lock hole 36, the loss or theft of the junction box body 2 can be reduced, and it is simple and convenient to use.

The eccentric wheel 16 can be restricted so that it cannot rotate by inserting the screw 39 into the through hole 37 and screwing one end of the screw 39 into the threaded hole 38. At this time, the movable plate 7 can be further restricted by the eccentric wheel 16, reducing the insertion of the first plug plate 23 into the first slot 24. When the eccentric wheel 16 is released, there is a gap between the groove wall of the first slot 24 close to the pressure plate 9 and the first plug plate 23, which causes the sealing gasket 6 on the junction box body 2 to be pressed against the photovoltaic panel 1. The outer wall of the screw 39 is wrapped with raw tape.
