[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-5 As shown, a water-blocking charging gun includes a body 1 and a charging plug 2 connected to the body 1. An annular groove 7 is provided at one end of the body 1 close to the charging plug 2. An annular convex plate 8 is slidably connected in the groove 7. A ring plate 5 is fixedly connected to one side of the convex plate 8. An annular inner support 9 is provided on the inner wall of the groove 7. An annular outer support 10 is fixedly connected to the outer wall of the convex plate 8. The outer support 10 is located between the inner support 9 and the bottom of the groove 7, and the outer support 10 is limited by the inner support 9; a plurality of springs 6 are provided in the groove 7, and a first connecting column 16 is fixedly connected to the bottom of the groove 7. The convex plate 8 is away from the side of the ring plate 5. It is fixedly connected with a second connecting column 17, one end of the spring 6 is clamped with the first connecting column 16, and the other end is clamped with the second connecting column 17, which is convenient for installing and disassembling the spring 6; the side of the ring plate 5 away from the spring 6 is fixedly connected with a sealing gasket 3, which is arranged around the charging plug 2. The sealing gasket 3 seals and waterproofs the gap between the fuselage 1 and the outer wall of the charging port 4. The setting of the spring 6 allows the sealing gasket 3 to seal the outer walls of the charging port 4 of different lengths, and utilizes the elastic action of the spring 6 to strengthen the extrusion of the sealing gasket 3 and the outer wall of the charging port 4, thereby enhancing the sealing effect.

[0028] An arc-shaped fixing plate 11 is provided on the outer wall of the fuselage 1, and the fixing plate 11 is fixedly connected to the inner support 9 through a connecting plate 12. A number of first screw holes 13 are distributed circumferentially on the fixing plate 11, and second screw holes 14 corresponding to the first screw holes 13 are provided on the outer wall of the fuselage 1. The first screw holes 13 and the second screw holes 14 are connected by screws 15. The detachable structure can disassemble the inner support 9, which is convenient for replacing the spring 6 and avoiding the reduction of the squeezing effect on the cushion 3 after the elastic effect of the spring 6 decreases; a handle 18 is connected to the end of the fuselage 1 away from the charging plug 2, and the handle 18 is wrapped with an anti-slip pad 19, and the anti-slip pad 19 is provided with anti-slip grooves 20 to increase friction; a lock switch 21 is provided on the top of the fuselage 1 for unlocking the charging gun.

[0029] Working principle:

[0030] like Figure 1-5 As shown, when the water-blocking charging gun of the present application is in use, when the charging plug 2 of the charging gun is inserted into the charging port 4 of the electric vehicle and locked, the outer wall of the charging port 4 will contact the sealing gasket 3 and push the sealing gasket 3 to move closer to the body 1, and the sealing gasket 3 will compress the spring 6 through the ring plate 5. The elastic action of the spring 6 will push the sealing gasket 3 and the outer wall of the charging port 4 to be squeezed, so that a sealed state is formed between the body 1 and the outer wall of the charging port 4, so that rainwater cannot flow into the gap between the outer wall of the charging plug 2 and the inner wall of the charging port 4, thereby avoiding the erosion of the charging port 4 by rainwater, reducing the damage caused by rainwater to the electric vehicle, and preventing the occurrence of safety hazards.
