[0028] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0029] Example:

[0030] The following is combined with Figure 1-6 The utility model is described in further detail.

[0031] See also Figure 1-6 The utility model provides a technical solution: a conversion connector for a charging gun, comprising a first base 1 and a second base 3, one side of the first base 1 is fixedly connected with a national standard socket end 2, one side of the second base 3 is fixedly connected with a European and American standard plug end 4, and the national standard socket end 2 is connected to the European and American standard plug end 4 through a connecting line 13;

[0032] A first protective shell 11 is fixedly connected to the other side of the first base 1, and a telescopic device 12 is provided on one side of the bottom of the first protective shell 11. A second protective shell 14 is fixedly connected to the other side of the second base 3. By providing a connecting line 13, a first protective shell 11, a second protective shell 14 and a telescopic device 12, etc., it is convenient to adjust according to different usage conditions, suitable for different charging scenes and charging positions, and the connecting line 13 is stored when going out for easy carrying. Two limiting grooves 15 are provided at the bottom of the second protective shell 14, and the telescopic device 12 cooperates with the limiting grooves 15;

[0033] The telescopic device 12 includes a protective frame 121, which is fixedly connected to one side of the bottom of the first protective shell 11. A first slide groove 122 is provided at the bottom of the protective frame 121. A stopper 123 is slidably connected in the first slide groove 122. A spring 124 is provided between the first slide groove 122 and the stopper 123. Second slide grooves 125 are provided on both sides of the first slide groove 122. Slide blocks 126 are fixedly connected on both sides of the stopper 123. The two slide blocks 126 are slidably connected in the two second slide grooves 125 respectively.

[0034] Specifically, the first protective shell 11 is concentrically sleeved in the second protective shell 14, and the distance from any point on the outer surface of the first protective shell 11 to any point on the inner wall of the second protective shell 14 is greater than zero. Support seats 6 are fixedly connected on both sides of the first base 1, and support rods 7 are rotatably connected to the two support seats 6 through pins. The other ends of the two support rods 7 are threadedly connected to screws 8, and the other ends of the two screws 8 are rotatably connected to baffles 9, and the two screws 8 are provided with square twisting parts 10.

[0035] By adopting the above technical solution, the first protective shell 11 and the second protective shell 14 are used to facilitate the storage of the connecting line 13. The distance from any point on the outer surface of the first protective shell 11 to any point on the inner wall of the second protective shell 14 is greater than zero, which means that when the first protective shell 11 is inserted into the second protective shell 14, there is a certain gap between the outer surface of the first protective shell 11 and the inner wall of the second protective shell 14, which is convenient for adjustment during insertion. The support rod 7, the screw 8 and the baffle 9 are used to facilitate the clamping and limiting of the connection position, so that the connection position is more stable.

[0036] Specifically, the tops of the first base 1 and the second base 3 are fixedly connected with handles 5, and the two handles 5 cooperate with each other. The first protective shell 11 is provided with a plurality of first heat dissipation openings 16, and the second protective shell 14 is provided with a plurality of second heat dissipation openings 17, and the plurality of first heat dissipation openings 16 and the plurality of second heat dissipation openings 17 cooperate with each other.

[0037] By adopting the above technical solution, the handle 5 is used to facilitate the connection of the operator during charging and to facilitate carrying. The first heat dissipation port 16 and the second heat dissipation port 17 are used to dissipate heat during use and are sealed when not in use.

[0038] The working principle of the utility model is as follows: when in use, the national standard socket end 2 and the charging gun socket are inserted and connected through the handle 5, and the baffle 9 is adjusted to a suitable position by rotating the support rods 7 on both sides of the first base 1, and the square screwing part 10 is screwed to drive the screw 8 to rotate into the support rod 7, and the baffle 9 is driven to approach the first base 1, so that the national standard socket end 2 and the charging gun socket are clamped and limited, so that the connection position is more stable, and the European and American standard plug end 4 is inserted into the car charging port, and the car is charged by power supply, and the first protective shell 11 is removed from the second protective shell 14, so as to separate the first base 1 and the second base 3, and the power supply is connected through the connecting line 13, which can be used for adjustment at positions where the charging line is not long enough and the charging angle is not good;

[0039] After charging is completed, remove the national standard socket end 2 and the European and American standard plug end 4, press the stopper 123 to enter the first slide groove 122, insert the first protective shell 11 into the second protective shell 14, and store the connecting line 13. When moving to a suitable position, the spring 124 undergoes elastic deformation when the stopper 123 enters the first slide groove 122. When the stopper 123 moves to the limiting groove 15, the spring 124 rebounds to push the stopper 123 to enter the limiting groove 15, limit the first protective shell 11 and the second protective shell 14, and seal the first protective shell 11 through the cooperation of the first heat dissipation port 16 and the second heat dissipation port 17, so that the staff can carry it conveniently.
