[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 In the utility model: a sealing structure of a modular power supply, including a power supply body 1, a buffer ring 2 is fixedly connected to the top of the power supply body 1, the buffer ring 2 is a rubber layer, a top plate 3 is fixedly connected to the top of the buffer ring 2, a shell 4 is threadedly connected to the top plate 3, a threading hole 5 is opened on the top plate 3 for the power cord of the power supply body 1 to pass through, an air bag 6 is embedded in the inner wall of the threading hole 5, a fixing ring 7 is fixedly connected to the inner wall of the shell 4, and a sealing ring 8 is fixedly connected to the top of the fixing ring 7.

[0027] In the present invention, when in use, first align the top plate 3 with the shell 4, and then the user rotates the top plate 3 or the shell 4 to rotate the top plate 3 to the inside of the shell 4. During the process of the top plate 3 being screwed into the shell 4, the bottom of the top plate 3 will continue to approach the sealing ring 8 until the top plate 3 and the sealing ring 8 are tightly attached, thereby completing the installation of the top plate 3. At this time, the power supply body 1 will be wrapped by the shell formed by the top plate 3 and the shell 4, thereby protecting the power supply body 1 from the influence of the external environment. During the process, the sealing ring 8 can effectively seal between the top plate 3 and the shell 4, thereby improving the protection effect of the power supply body 1. The setting of the airbag 6 can seal between the power cord of the power supply body 1 and the threading hole 5, thereby improving the sealing effect of the device. When the user maintains the power supply body 1, the user only needs to rotate the top plate 3 in the opposite direction to take out the power supply body 1, which is convenient for the user to disassemble.

[0028] See also Figures 1 to 4 , wherein: the top of the top plate 3 is sleeved with a rotating ring 9 movably connected to it, the top plate 3 is provided with a ring-shaped cavity 10, the inner wall of the cavity 10 is slidably connected to a piston plate 11, the top of the piston plate 11 is fixedly connected to a connecting rod 12, the top of the connecting rod 12 passes through the top plate 3 and is fixedly connected to a connecting plate 13, the bottom of the connecting plate 13 is in contact with the rotating ring 9, the inner wall of the cavity 10 is fixedly connected to a limiting ring 14, and a catheter 15 is connected between the cavity 10 and the airbag 6.

[0029] In the present invention, when the top plate 3 is screwed into the shell 4, the rotating ring 9 will first contact the top of the shell 4. As the top plate 3 moves, the rotating ring 9 will drive the piston plate 11 to slide inside the cavity 10 through the connecting plate 13 and the connecting rod 12. During the process, the air in the cavity 10 will be pushed into the airbag 6 from the conduit 15 until the top plate 3 is tightly attached to the sealing ring 8. At this time, the piston plate 11 will contact the limiting ring 14. At this time, the inside of the airbag 6 will expand due to the addition of air. The expansion of the airbag 6 will be tightly attached to the power cord of the power supply body 1, thereby improving the sealing effect between the power cord and the threading hole 5, thereby improving the practicality of the device.

[0030] See also Figure 4 , wherein: a rubber ring 16 is fixedly connected to the bottom of the rotating ring 9, and the rubber ring 16 is a rubber layer.

[0031] In the present invention, the provision of the rubber ring 16 can perform sealing between the rotating ring 9 and the housing 4, further improving the sealing effect of the device.

[0032] See also Figures 1 to 3 , wherein: the top of the top plate 3 is fixedly connected to a fixing rod 17, and the top end of the fixing rod 17 is rotatably connected to a handle 18.
