[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a leakage protection device for a charging pile, referring to Figure 1-Figure 4 , including a charging pile body 1, a protection box 2 is fixedly installed at both ends of the charging pile body 1, and a charging line 3 is symmetrically fixedly connected to the two ends of the bottom of the charging pile body 1. The upper end of the charging line 3 passes through the protection box 2 and is fixedly connected to a charging head 4. By arranging the protection box 2 at both ends of the charging pile body 1, the charging line 3 is protected during daily placement, which effectively prevents the charging line 3 from being damaged by ultraviolet rays, rain and snow or man-made accidents when not in use, thereby enhancing the protection effect of the charging line 3. A mounting seat 5 is fixedly installed in the middle of the two side surfaces of the charging pile body 1, and the mounting seat 5 is used to fix the wire reel 6. The surface of the mounting seat 5 is rotatably connected to the wire reel 6, and a plurality of wire reel grooves 7 are provided on the outer surface of the wire reel 6. The wire reel groove 7 is spiral and the middle part of the charging line 3 is spirally wound around the outer side of the wire reel 6 through the wire reel groove 7. The charging line 3 can be reeled in the protective box 2 by rotating the wire reel 6 and cooperating with the wire reel groove 7, so that the cable is not stretched and folded at will after use, thereby extending its service life.

[0023] Reference Figure 3-Figure 4 A shell body 9 is fixedly connected to the middle part of the outer side of the protection box 2, and a connecting rod 8 is fixedly installed on one end of the wire take-up reel 6 away from the mounting seat 5. The other end of the connecting rod 8 passes through the protection box 2 and is installed with a linkage gear 10. Under the action of the connecting rod 8, when the wire take-up reel 6 rotates, the linkage gear 10 rotates synchronously. The linkage gear 10 is arranged on the inner side of the shell body 9, and a brake handle 11 is fixedly installed on the outer surface of the linkage gear 10. The brake handle 11 can drive the linkage gear 10 to rotate, thereby driving the wire take-up reel 6 to rotate, so that the charging line 3 can be reeled up after use.

[0024] Reference Figure 4The side of the housing 9 is movably connected to two movable rods 12, and an arc-shaped rack plate 13 is fixedly installed at one end of the two movable rods 12 close to the linkage gear 10. The inner side of the arc-shaped rack plate 13 is meshed and connected with the side of the linkage gear 10. The teeth on the inner side of the arc-shaped rack plate 13 are used to limit the linkage gear 10, which is convenient for fixing the charging cable 3 at the lower limit when it is placed or used in daily life, so that the charging cable 3 will not be stretched at will, ensuring that the charging cable 3 is always at a suitable length for charging or winding, which is more convenient to use. Two return springs 14 are fixedly installed on one end of the rack plate 13 close to the movable rod 12, and the two return springs 14 are respectively sleeved on the outside of the two movable rods 12. The other end of the return spring 14 is fixedly installed on the inner wall of the shell 9. When the limit plate 15 is loosened, the thrust of the two return springs 14 is utilized to make the arc-shaped rack plate 13 tightly connected to the side of the linkage gear 10 to ensure the stability of the take-up reel 6. The limit plate 15 is fixedly installed on one end of the two movable rods 12 away from the arc-shaped rack plate 13, and the limit plate 15 plays a limiting role on the movable rod 12.

[0025] The implementation principle of a leakage protection device for a charging pile in an embodiment of the present application is as follows: when using the device, the limit plate 15 can be pulled first to make the movable rod 12 drive the arc-shaped rack plate 13 to disengage from the linkage gear 10, thereby releasing the lock of the linkage gear 10, and then pulling the charging head 4 to drive the charging cable 3 to charge the vehicle, and then loosening the limit plate 15 so that the arc-shaped rack plate 13 is reconnected to the side of the linkage gear 10 through the thrust of the reset spring 14 to lock the wire reel 6 inside the protection box 2. After use, the limit plate 15 is pulled outward in the same way, and then the brake handle 11 is turned to drive the wire reel 6 to rotate, and the charging cable 3 is wound up and protected, and finally the limit plate 15 is loosened to make the arc-shaped rack plate 13 lock the linkage gear 10 again.
