[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figures 1-6 The energy storage cabinet door fastening device shown comprises a cabinet body 1, a partition plate 2 is fixedly connected to the left interior at the center of the front end of the cabinet body 1, door bodies 3 are rotatably connected to the left and right sides of the front end of the cabinet body 1 through hinges, and the width of the right door body 3 is greater than that of the left door body 3, and can be respectively fitted to the left and right sides of the front end of the partition plate 2 by rotation, and a connecting base 4 is fixedly connected to the lower end of the cabinet body 1. By arranging energy storage equipment and power distribution equipment inside the cabinet body 1, the energy storage cabinet can protect the energy storage equipment and the power distribution equipment through the cabinet body 1, and the energy storage equipment and the power distribution equipment are separately managed through the partition plate 2 inside the cabinet body 1, and the energy storage cabinet can be connected and fixed through the connecting base 4 at the lower end of the cabinet body 1, and the cabinet body 1 can be closed at the front end by closing the two door bodies 3 arranged at the front end, so that the interior of the cabinet body 1 is in a fully closed state, which can better protect the internal energy storage equipment and power distribution equipment, and at the same time, the cabinet body 1 can maintain and repair the internal energy storage equipment and power distribution equipment by opening the two door bodies 3 at the front end.

[0028] Preferably, a support plug plate 5 is fixedly connected to the interior of the front side of the inner wall at the lower end of the cabinet body 1 by bolts, and the support plug plate 5 is located on the right side of the partition plate 2, and two support clamps 6 are fixedly connected to the front lower corner of the left end of the door body 3 by a bolt assembly, and the two support clamps 6 can be engaged with the support plug plate 5 through the rotation of the door body 3. When the door body 3 on the right side is closed, since the door body 3 on the right side is larger and heavier, the hinge connected to the cabinet body 1 can be easily pulled and deformed by gravity during long-term use, causing the door body 3 on the right side to sag and fail to fit tightly with the cabinet body 1, making it difficult to clean the inside of the cabinet body 1. The equipment is protected. At this time, the cabinet body 1 and the door body 3 in the closed state are reinforced by the support plate 5 arranged on the inner wall of the lower end of the cabinet body 1 and the two support clamps 6 arranged on the lower side of the left end of the door body 3. The two support clamps 6 can be connected to the upper and lower sides of the front end of the support plate 5 arranged in a "Z" shape through the rotation of the door body 3, so that the support plate 5 is clamped between the two support clamps 6, so that the support plate 5 and the support clamps 6 can lift the cabinet body 1 and the door body 3 away from the lower side of the hinge end, preventing the door body 3 from pulling and deforming the hinge under the action of gravity, and during the transportation of the energy storage cabinet, it can also prevent the door body 3 from sagging due to bumps.

[0029] Preferably, a secondary support ring 7 is slidably connected inside the lower right corner at the front end of the cabinet body 1. An inner support ring 8 is slidably connected inside the front end of the secondary support ring 7. The other end of the inner support ring 8 is fixedly connected to the lower right corner at the rear end of the right door body 3 by bolts. During the opening and closing process of the right door body 3, since the right door body 3 will pull the hinge under the action of gravity, the frictional resistance inside the hinge is relatively large, making it difficult to open and close. At this time, the door body 3 can be supported at the lower end through the secondary support ring 7 and the inner support ring 8 provided on the lower right side between the cabinet body 1 and the door body 3, so that the door body 3 will not pull the hinge under the action of gravity, making the engagement of the larger right door body 3 smoother.

[0030] Preferably, a roller groove 9 runs through the upper end of the support clamp block 6 vertically. A clamping roller 10 is rotatably connected to the center of the roller groove 9. The upper and lower ends of the clamping roller 10 protrude outside the roller groove 9. The clamping roller 10 is rotatably connected to the roller groove 9 through an adjustment roller shaft 11, and the adjustment roller shaft 11 runs through the center of the clamping roller 10 from front to back. During the process of the two support clamp blocks 6 being clamped to the front end of the support insertion plate 5, the two support clamp blocks 6 are clamped to the front end of the support insertion plate 5 through the two clamping rollers 10 provided inside, and are smoothly clamped on the upper and lower sides of the front end of the support insertion plate 5 by rolling on the outer walls on the upper and lower sides of the front end of the support insertion plate 5 by the clamping rollers 10.

[0031] Preferably, square adjustment sliders 12 are fixedly connected to both the front and rear ends of the adjustment roller shaft 11. The two adjustment sliders 12 are slidably connected to the inside of the front and rear ends of the support clamp block 6 through adjustment chutes 13. The two adjustment chutes 13 run through the centers of the front and rear ends of the support clamp block 6 from front to back respectively. During the installation of the support insertion plate 5 and the two support clamp blocks 6, it is necessary to adjust the positions between the two clamping rollers 10 and the support insertion plate 5 so that the two clamping rollers 10 can just be clamped on the upper and lower sides of the front end of the support insertion plate 5. Since the adjustment roller shaft 11 can slide up and down inside the roller groove 9 through the adjustment slider 12, the clamping roller 10 can adjust its position inside the roller groove 9 by the up and down sliding of the adjustment roller shaft 11, enabling the two clamping rollers 10 to adjust their up and down positions, so that the two clamping rollers 10 can smoothly roll on the outer walls on the upper and lower sides of the front end of the support insertion plate 5 during the closing process of the door body 3, enabling the door body 3 to close smoothly, and at the same time supporting the lower side of the end of the door body 3 away from the hinge.

[0032] Preferably, threaded holes 14 are communicated with the centers of the upper and lower ends of the two positioning sliding grooves 13, and the four threaded holes 14 respectively penetrate through the left and right sides inside the centers of the upper and lower ends of the support clamping block 6. Straight bolts 15 are arranged at the centers of the upper and lower ends of the positioning sliding block 12, and the two straight bolts 15 are respectively threadedly connected to the two threaded holes 14 communicated with the upper and lower ends of the positioning sliding groove 13. During the process of adjusting the positions of the clamping rollers 10 and the positioning rollers 11, the adjustment can be carried out through the two straight bolts 15 arranged at the upper and lower ends of the positioning sliding block 12. Since the two straight bolts 15 are clamped at the upper and lower ends of the positioning sliding block 12 and can move up and down by screwing, the up and down position of the positioning sliding block 12 can be adjusted by screwing the two straight bolts 15, and the position of the positioning sliding block 12 can be fixed by clamping, so that the positions of the two clamping rollers 10 are adjustable, which is more convenient for the installation and debugging of the energy storage cabinet.

[0033] Preferably, a telescopic groove 16 is opened inside the right front corner of the lower end inner wall of the cabinet body 1, and the secondary support ring 7 is slidably connected inside the telescopic groove 16. Since the secondary support ring 7, the primary support ring 8 and the telescopic groove 16 are all arranged in a fan-shaped ring, and the central axis of the fan-shaped ring coincides with the rotation axis of the hinge. At the same time, a plurality of balls 18 are rotatably connected inside the upper and lower ends of the secondary support ring 7 and the primary support ring 8, so the secondary support ring 7 can smoothly slide inside the telescopic groove 16 through the plurality of balls 18, and the primary support ring 8 can smoothly slide inside the secondary support ring 7 through the plurality of balls 18. And the secondary support ring 7 can be completely retracted into the telescopic groove 16, and the primary support ring 8 can be completely retracted into the secondary support ring 7, so that the secondary support ring 7 and the primary support ring 8 can expand and contract following the opening and closing of the door body 3, thereby ensuring that the secondary support ring 7 and the primary support ring 8 can always support the bottom of the door body 3, preventing the door body 3 from pulling the hinge under the action of gravity and causing deformation. At the same time, the secondary support ring 7 and the primary support ring 8 do not prevent the fitting between the door body 3 and the cabinet body 1, ensuring that the door body 3 can close the front end of the cabinet body 1.

[0034] Preferably, a telescopic sliding hole 17 is clamped inside the upper end of the telescopic groove 16, and the telescopic sliding hole 17 is fixedly connected to the inside of the upper end of the telescopic groove 16 through a plurality of bolts. Limiting blocks are arranged at the rear ends of the secondary support ring 7 and the primary support ring 8. The upper end of the telescopic groove 16 can be opened by removing the telescopic sliding hole 17, so that the secondary support ring 7 and the primary support ring 8 inside the telescopic groove 16 can be more conveniently maintained and repaired. And the secondary support ring 7 and the primary support ring 8 can prevent each other from separating through the limiting blocks, and can prevent the secondary support ring 7 from separating from the inside of the telescopic groove 16, making the connection between the secondary support ring 7 and the primary support ring 8 more stable, so that the support of the secondary support ring 7 and the primary support ring 8 for the door body 3 is more stable.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
