Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 As shown, an AC charging pile of an embodiment of the utility model includes a base 1 and a charging pile body 2, an assembly block 20 is fixedly provided at the bottom of the charging pile body 2, and limiting grooves 21 are provided on the front and rear sides of the assembly block 20, an assembly groove 10 is provided at the center of the top surface of the base 1, and an accommodating recess 11 extends from the opening of the assembly groove 10, and a plurality of groups of fixing seats 3 are arranged in pairs at the front and rear sides of the assembly groove 10, and a card block 30 adapted to the limiting groove 21 is movably connected to the fixing seat 3, and an adjustment mechanism for controlling each card block 30 to synchronously extend into or out of the assembly groove 10 is built in the accommodating recess 11.

[0020] During use, when installing the charging pile body 2, align the assembly block 20 at the bottom of the charging pile body 2 with the assembly groove 10 and push it in, and then control the synchronous rotation of each card block 30 through the adjustment mechanism, the card block 30 rotates from the accommodating recess 11 into the assembly groove 10 and enters the limit groove 21, and the installation and fixation of the charging pile is completed through the limit clamping formed by each card block 30 and the limit groove 21. When the charging pile needs to be disassembled, the opposite operation can be performed.

[0021] A pivot 31 is rotatably provided on the fixed seat 3, and one end of the pivot 31 is located below the fixed seat 3 and is fixedly connected to the block 30, and one end of the pivot 31 is located above the fixed seat 3 and is connected to a gear 32; the adjustment mechanism includes a movable part 4 slidably arranged in the accommodating recess 11, the movable part 4 is a U-shaped structure, and the inner sides of the two vertical parts are formed with a meshing part 40 that cooperates with the gear 32, and the meshing part 40 has a plurality of tooth blocks 41 arranged in an array; a plurality of guide seats 12 are arranged in the accommodating recess 11 at the corresponding positions of the two vertical parts of the movable part 4, and the movable part 4 is slidably matched with the guide seats 12; a screw rod 5 is rotatably provided on the inner wall of the left side of the accommodating recess 11, the inner end of the screw rod 5 passes through the transverse part of the movable part 4 and is connected to a supporting seat 50, and a threaded sleeve 51 is fixedly provided on the movable part 4 at the corresponding position of the screw rod 5; a groove 13 is opened at the left side of the base 1 at the corresponding position of the screw rod 5, and the outer end of the screw rod 5 extends through the groove 13 and is connected to a knob 52.

[0022] When in use, the knob 52 is turned forward and the screw rod 5 is driven to rotate. The inner end of the screw rod 5 is rotatably connected to the support seat 50. The screw rod 5 rotates through the threaded connection between the threaded sleeve 51 and the sliding cooperation between the movable member 4 and the guide seat 12, driving the movable member 4 to slide radially to the right along the accommodating recess 11. The movable member 4 slides to the right through the meshing cooperation between its meshing portion 40, the tooth block 41 and the gear 32, driving the pivot 31 to rotate.
