[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1-4 This utility model discloses a child-proof charger plug self-locking device, comprising a charger body 1. A plug 2 is fixedly connected to the right side of the charger body 1 for convenient charging. A rotating rod 21 is rotatably connected to the front right side of the charger body 1. A protective shell 3 is fixedly connected to the outside of the rotating rod 21, protecting the charger plug 2. Two magnets 6 are fixedly connected to the front of the protective shell 3, which, in conjunction with a metal piece 7, limit the movement of the protective shell 3. Two connecting pieces 16 are fixedly connected to the rear of the protective shell 3, serving a connecting function. Connecting blocks 4 are fixedly connected to the outside of each connecting piece 16, with insertion holes 5 at the bottom of the connecting blocks 4, also serving a limiting function. Two fixing cylinders 8 are fixedly connected to the rear of the charger body 1, positioned below the connecting blocks 4 to facilitate the alignment of telescopic grooves 9 with the insertion holes 5. Both fixed cylinders 8 have telescopic grooves 9 at their tops. A pull rod 10 is slidably connected through the telescopic groove 9. A plug 11 is fixedly connected to the top of the pull rod 10. The pull rod 10 can drive the plug 11 to move. A lever 12 is provided at the bottom of the fixed cylinder 8. A wire harness assembly is connected to the top and bottom of the charger body 1.

[0033] Reference Figure 4 The cable harness assembly includes a mounting post 15, which is fixedly connected to the top and bottom of the charger body 1. A limiting groove 17 is provided on the outer side of the mounting post 15. A bidirectional threaded rod 23 is rotatably connected through the limiting groove 17. Movable posts 19 are threadedly connected to both sides of the outer ring of the bidirectional threaded rod 23. A limiting plate 20 is fixedly connected to the outer side of each of the two movable posts 19. An anti-slip pad 22 is fixedly connected to the adjacent side of the two movable posts 19. A knob 18 is fixedly connected to the left end of the bidirectional threaded rod 23, and the knob 18 is located on the outer side of the mounting post 15. When the bidirectional threaded rod 23 of the cable harness assembly is rotated, it can drive the two movable posts 19 and the limiting plate 20 to move relative to each other, thereby fixing the data cable wrapped around the outside of the charger body 1, preventing the data cable from becoming loose, and making it easy to carry.

[0034] Reference Figure 1 , Figure 2 and Figure 3The protective shell 3 is located on the outside of the plug pin 2, protecting the plug pin 2 from accidental contact by children. Two metal plates 7 are fixedly connected to the front of the charger body 1, and these metal plates 7 are attracted to the magnet 6, allowing the protective shell 3 to be positioned correctly during charging. The plug 11 is located within the telescopic groove 9, and its exterior is slidably connected to the inner wall of the telescopic groove 9, facilitating its extension and retraction within the groove. A rotating shaft 13 is rotatably connected through the center of the lever 12, and its exterior is connected to the bottom of the pull rod 10. The lever 12 and the pull rod 10 are connected via the rotating shaft 13. A spring 14 is sleeved on the outside of the pull rod 10, and the spring 14 is located within the telescopic groove 9. The spring 14's reset mechanism allows the plug 11 to extend from the telescopic groove 9 and insert into the socket 5.

[0035] Working principle: When using the charger, pull down the lever 12, so that the lever 12 rotates 90° and the bottom of the lever 12 is perpendicular to the bottom of the fixed cylinder 8 for limiting. At this time, the lever 12 rotates around the pivot 13, which can pull the lever 10. The lever 10 drives the plug 11 to compress the spring 14 and retract into the telescopic groove 9. At this time, the plug 11 is disengaged from the plug hole 5 of the connecting block 4, and the protective shell 3 can be opened. The magnet 6 on the outside of the protective shell 3 attracts the metal piece 7 on the outside of the charger body 1, thereby limiting the protective shell 3. Charging can be performed through pin 2. When the charger is not in use, the protective shell 3 covers the outside of pin 2 under the connection of the rotating rod 21, which protects the pin 2 and prevents children from accidentally touching it. At the same time, the lever 12 is pulled back, at which time the spring 14 in the telescopic groove 9 is reset, which drives the plug 11 to extend out of the telescopic groove 9 and insert into the plug hole 5 at the bottom of the connecting block 4, thus completing the installation of the protective shell 3. When it is necessary to organize the charging cable, the charging cable is wound between the two moving posts 19 on the outside of the charger body 1. After winding, the knob 18 is turned to drive the bidirectional threaded rod 23 to move relative to each other. The bidirectional threaded rod 23 drives the two moving posts 19 and the limiting plate 20 to move relative to each other, which fixes the wound charging cable to prevent it from loosening and makes it easy to carry.
