[0026] When in use, the heat dissipation mechanism works to draw external air into the charging pile through the air inlet shell 8 and the air inlets 7 in sequence, so as to exchange with the air in the charging pile with heat, and the speed of air circulation inside and outside is accelerated through the cooperation of the ventilation openings on both sides, so as to bring the hot air inside to the outside of the charging pile, thereby achieving the purpose of heat dissipation and cooling.

[0027] Symmetrical movable cavities are arranged inside one side of the charging pile 2, the clamping mechanism comprises a sliding plate 9 slidably installed in the movable cavity, slide rods 11 symmetrically arranged on one side of the sliding plate 9, and a pressing plate 10 fixed at one end of the two slide rods 11, a first spring 12 is fixedly connected between the sliding plate 9 and the movable cavity, the two slide rods 11 are both penetrated to the outside of the charging pile 2 and connected with the pressing plate 10, and a pull ring is fixed outside the pressing plate 10.

[0028] When the charging of the charging power line 5 is completed, the pressing plate 10 can be pulled outward through the pull ring, so that the pressing plate 10 moves away from the charging pile 2, at this time the first spring 12 is in a compressed state, so that the charging power line 5 can be inserted into the pressing plate 10, and when the pull ring is released, the pressing plate 10 is clamped outside the charging power line 5 under the elastic force of the first spring 12, so as to fix the charging power line 5 between the pressing plate 10 and the charging pile 2, thereby facilitating the arrangement and storage of the charging power line 5.

[0029] Dust plates are respectively and obliquely installed outside the plurality of ventilation openings 6, which can block dust from entering the inside of the charging pile.

[0030] The dustproof assembly comprises a square frame 13 matched with the air inlet shell 8 and a dustproof filter screen 14 fixed in the square frame 13, and positioning rods 15 are symmetrically and slidingly installed at two ends of the square frame 13, and positioning holes matched with the positioning rods 15 are symmetrically formed in the side wall of the air inlet shell 8.

[0031] Positioning cavities are symmetrically formed in the square frame 13 at the two ends, and a movable rod 16 is fixedly arranged in the middle of the positioning cavities, a second spring 17 and a movable plate 18 are slidingly sleeved on the outer side of the movable rod 16, one end of the second spring 17 is fixedly connected with the movable plate 18, the other end is fixedly connected with the inner wall of the positioning cavity, one end of the positioning rod 15 penetrates into the positioning cavity and is connected with the movable plate 18, and a through slot is formed in one side of the positioning cavity, and a push piece fixedly connected with the movable plate 18 is slidingly installed in the through slot.

In actual use, the buffer oil can be filled below the buffer sleeve 26. When the buffer rod 27 moves downward, the buffer oil in the buffer sleeve 26 flows to the upper side through the through hole, and is buffered by compressing the third spring 30 and the telescopic rod 29.
