[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the present utility model provides a technical solution: a energy storage bidirectional inverter, which includes a mounting base 1, an inverter main body 11, and a mounting component for fixing the inverter main body 11. The mounting component includes a cavity 21 opened inside the mounting base 1, a rotating shaft 22 connected to the inner wall of the cavity 21, a gear 23 fixedly connected to the outer side of the rotating shaft 22, racks 24 respectively connected to both sides of the gear 23, a connecting rod 25 fixedly connected to one side of the rack 24, a limiting plate 26 fixedly connected to one end of the connecting rod 25, slots 27 respectively opened on both sides of the inverter main body 11, a plug board 28 fixedly connected to one side of the limiting plate 26, and a pop-up component for improving the disassembly efficiency. The gear 23 meshes with the racks 24. The connecting rod 25 penetrates through the cavity 21 and is slidably connected to the mounting base 1. The rotating shaft 22 is rotatably connected to the inner wall of the cavity 21. The plug board 28 is inserted into the slot 27. Rotating the rotating shaft 22 can control the rotation of the gear 23. The rotation of the gear 23 can make the two racks 24 move in opposite directions, and then can drive the two connecting rods 25 and the limiting plate 26 to move. The movement of the limiting plate 26 can limit and fix the inverter main body 11. At the same time, the plug board 28 can be inserted into the slot 27 to prevent the inverter main body 11 from shifting vertically, so that the inverter main body 11 can be quickly installed and disassembled, and the disassembly and assembly efficiency can be improved. A worm gear 41 is fixedly connected to the outer side of the rotating shaft 22. A worm 42 is provided on one side of the worm gear 41. One end of the worm 42 is fixedly connected to a rotating plate 43. A handle 44 is fixedly connected to the front surface of the rotating plate 43. The worm 42 meshes with the worm gear 41. The worm 42 is rotatably connected to the mounting base 1. By rotating the handle 44, the rotating plate 43 can be driven to rotate, and then the worm 42 can be driven to rotate. The rotation of the worm 42 can drive the worm gear 41 to rotate, and then can drive the two limiting plates 26 to move. At the same time, by using the self-locking characteristic of the worm 42 and the worm gear 41, the limiting plate 26 can be prevented from moving randomly, and then the fixing stability of the inverter main body 11 can be ensured. Guide grooves 51 are respectively opened on both sides of the top of the mounting base 1. A guide block 52 is fixedly connected to the bottom of the limiting plate 26. The guide block 52 is slidably connected to the guide groove 51. The guide block 52 can move synchronously with the limiting plate 26, and then can prevent the rack 24 from disengaging from the gear 23, ensuring the stability of the movement of the rack 24 and the limiting plate 26. The shape of the guide groove 51 is T-shaped, and the shape of the guide block 52 is T-shaped, which can prevent the guide block 52 from vertically disengaging from the guide groove 51 and can limit the guide block 52. Mounting plates 71 are respectively fixedly connected to the four sides of the mounting base 1. Mounting holes 72 are opened on the top of the mounting plates 71. The mounting base 1 can be conveniently fixed through bolts, the mounting holes 72, and the mounting plates 71, and then the inverter main body 11 can be conveniently installed and disassembled.

[0024] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, the ejection component includes grooves 31 respectively formed on both sides of the top of the mounting base 1, through openings 32 formed on the inner bottom of the grooves 31, ejector rods 33 arranged in the through openings 32, top plates 34 fixedly connected to the tops of the ejector rods 33, connecting plates 35 fixedly connected to the bottoms of the ejector rods 33, and springs 36 fixedly connected to the tops of the connecting plates 35. The ejector rods 33 are slidably connected to the through openings 32, the top plates 34 are slidably connected to the grooves 31, both ends of the springs 36 are fixedly connected to the top of the connecting plate 35 and the inner top of the cavity 21 respectively, and the springs 36 are sleeved outside the ejector rods 33. When the inverter main body 11 is installed, its bottom can contact the top of the top plate 34 and push the top plate 34 downward. The downward movement of the top plate 34 can drive the ejector rod 33 to move downward, and then the spring 36 can be pulled to deform. When the restriction on the inverter main body 11 is released subsequently, the reset of the spring 36 can eject the inverter main body 11, which can improve the disassembly efficiency. Positioning grooves 61 are respectively formed on both sides of the bottom of the inverter main body 11, positioning blocks 62 are respectively fixedly connected to both sides of the top of the mounting base 1, and the positioning blocks 62 are inserted into the positioning grooves 61. The positioning blocks 62 can be inserted into the positioning grooves 61 to horizontally restrict the inverter main body 11, prevent the horizontal displacement of the inverter main body 11, and improve the installation stability of the inverter main body 11.

[0025] Working principle: During operation, the inverter main body 11 is placed on the top of the mounting base 1. At this time, the positioning block 62 can be inserted into the positioning groove 61. At the same time, the bottom of the inverter main body 11 contacts the top of the top plate 34 and pushes the top plate 34 downward. The downward movement of the top plate 34 can drive the connecting plate 35 to move downward. The downward movement of the connecting plate 35 can drive the spring 36 to deform. Then, the handle 44 can be rotated. The handle 44 can drive the rotating plate 43 to rotate. The rotation of the rotating plate 43 can drive the worm 42 to rotate. The rotation of the worm 42 can drive the worm gear 41 to rotate. The rotation of the worm gear 41 can drive the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 can drive the gear 23 to rotate. The rotation of the gear 23 can drive the two racks 24 to move towards the middle. The movement of the racks 24 can drive the connecting rod 25 to move. The movement of the connecting rod 25 can drive the limiting plate 26 to move. The movement of the limiting plate 26 can fix the inverter main body 11. At the same time, the insertion plate 28 can be inserted into the insertion slot 27 to improve the fixing effect on the inverter main body 11. When the inverter main body 11 needs to be disassembled and maintained subsequently, only need to rotate the handle 44 in the reverse direction to make the insertion plate 28 disengage from the insertion slot 27. At this time, the spring 36 can be reset, which can drive the top plate 34 to reset. The reset of the top plate 34 can eject the inverter main body 11, which can improve the disassembly efficiency and facilitate the taking of the inverter main body 11. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
