DETAILED DESCRIPTION

[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a waterproof structure of a charging gun for an electric vehicle charging pile, comprising a gun head 2 connected to one end of a charging gun body 1, a disassembly cylinder 12 is provided in a movable sleeve in the middle of the charging gun body 1, and the disassembly cylinder 12 is positioned and connected to the charging gun body 1 through a locking member 13; at least two locking members 13 are provided, and the locking members 13 are symmetrically arranged on both sides of the charging gun body 1;

[0022] Furthermore, if Figure 2 As shown, the locking member 13 includes a hollow block 131 fixed on the charging gun body 1, a bent spring piece 133 is arranged in the hollow block 131, the top of the bent spring piece 133 is bent upward, so that the bent spring piece 133 is triangular, and the bent spring piece 133 is elastically connected to the disassembly cylinder 12, and a locking block 136 matching with it is fixed in the hollow block 131, and the locking block 136 is set as a right triangle, and the locking block 136 is placed at the center of the triangular bent spring piece 133, and the inclined surface of the locking block 136 is used to limit the bent spring piece 133 to prevent the bent spring piece 133 and the hollow block 131 from separating, and a socket 135 for inserting the bent spring piece 133 is opened on the hollow block 131, so that the bent spring piece 133 compressed into a plane enters the hollow block 131 through the socket 135, and the locking block 136 is arranged close to the socket 135;

[0023] Furthermore, the locking member 13 includes a connecting arm 132 fixed to the disassembly cylinder 12, and a spring 134 is connected between the connecting arm 132 and the root of the bent spring sheet 133;

[0024] Specifically, since the hollow block 131 is fixed on the charging gun body 1, the disassembly cylinder 12 is limitedly connected with the charging gun body 1 through the slider, so that the disassembly cylinder 12 can only be moved to a specific position of the charging gun body 1. Only when the spring 134 is in an expanded state can the bent spring piece 133 enter the hollow block 131. Before inserting the bent spring piece 133 into the socket 135, the bent spring piece 133 needs to be pressed into a plane first, and then continue to push the bent spring piece 133 to move away from the spring 134, so that the bent spring piece 133 returns to a triangular shape. At this time, release your hand, and the bent spring piece 133 moves toward the socket 135 under the pulling force of the spring 134, and then cooperates with the locking block, so that the disassembly cylinder 12 and the charging gun body 1 are locked;

[0025] Furthermore, a pressing assembly 137 is provided on the top of the hollow block 131; the pressing assembly 131 is used to press the bent spring sheet 133 downward, so that the bent spring sheet 133 is compressed into a plane so that it can be separated from the hollow block 131;

[0026] Specifically, the pressing assembly 137 includes a pressing plate 1371, a connecting rod 1372 inserted into the hollow block 131 is fixed at the bottom of the pressing plate 1371, a push plate 1373 is fixed at the bottom of the connecting rod 1372, and a second spring 1374 is connected between the pressing plate 1371 and the hollow block 131; the pressing plate 1371 is pressed downward, so that the push plate 1373 compresses the bent spring sheet 133 downward, and the second spring 1374 is used to facilitate the reset of the pressing plate 1371 and the push plate 1373;

[0027] Specifically, by providing a locking piece 13 and a disassembly cylinder 12, the disassembly cylinder 12 is used as an anchor point for the guide cylinder 3, so that the guide cylinder 3 is indirectly connected to the charging gun body 1, and by removing the bent spring piece 133 from the hollow block 131, thereby cutting off the connection between the disassembly cylinder 12 and the charging gun body 1, the disassembly cylinder 12 can be removed, and the entire device can be quickly disassembled.

[0028] The outer fixed cover of the disassembly cylinder 12 is provided with a guide cylinder 3, the guide cylinder 3 is closed at one end close to the gun head 2, and the other end is open, and the outer cover of the gun head 2 is provided with a moving cylinder 8 threadedly connected with the guide cylinder 3;

[0029] Furthermore, the two ends of the guide cylinder 3 are fixed with limit plates 11, so that the movable cylinder 8 can only move between the limit plates 11, thereby preventing the movable cylinder 8 from being separated from the guide cylinder 3;

[0030] The movable cylinder 8 is hingedly connected to one end of the gun head 2 with a waterproof cover plate 9 that can be assembled. The waterproof cover plates 9 are all fixed with magnetic sealing strips 10, and the magnetism of adjacent magnetic sealing strips 10 is opposite; the magnetic sealing strip 10 includes a sealing strip fixed on a magnetic block, and the surface of the magnetic block is coated with a magnetic coating, and the magnetism of the magnetic coating on the magnetic blocks of adjacent magnetic sealing strips 10 is opposite;

[0031] Specifically, by setting the guide cylinder 3, the movable cylinder 8, the waterproof cover 9 and the magnetic sealing strip 10, the movable cylinder 8 is used to completely wrap the gun head 2, and then the waterproof cover 9 is used to cover the front of the gun head 2. Combined with the magnetic sealing strip 10, it is not only convenient to assemble the waterproof cover 9, but also can improve the sealing performance of the waterproof cover 9. Compared with the prior art, the gun head 2 is fully protected, which can not only prevent rainwater from entering the connection part between the gun head 2 and the charging gun body 1, but also prevent rainwater from entering the gun head 2, thereby achieving a good waterproof effect. At the same time, the movable cylinder 8 can be rotated to move left and right along the guide cylinder 3, so as to facilitate the adjustment of the position of the movable cylinder 8 for actual use.

[0032] Furthermore, a waterproof cover 4 is fixed to one end of the guide cylinder 3 close to the gun head 2, and downwardly inclined drainage plates 5 are fixed to the bottom of both ends of the waterproof cover 4 to facilitate the downward flow of rainwater. A mounting groove 6 is fixed to the inner wall of the waterproof cover 4, and a water stop strip 7 is installed in the mounting groove 6. The expanded water stop strip 7 is used to block the space between the waterproof cover 4 and the gun head 2, effectively preventing rainwater from entering the connection between the gun head 2 and the charging gun body 1, thereby achieving a good waterproof effect.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
