DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1-6 The utility model provides a technical solution: an AC-DC battery charging device, including a charger connection box 10, the lower ends of the left and right sides of the charger connection box 10 are fixedly connected to a slide 1, the front end of the charger connection box 10 is provided with a charger plug 9, the left and right ends of the charger connection box 10 are provided with an AC-DC battery charging head 8, the upper surfaces of the two slides 1 are provided with a fixing component, the fixing component includes a sliding card seat 11, multiple limiting rings 13, multiple springs 15, two support rods 12 and a pressure plate 4, the sliding card seat 11 is slidably connected to the square groove at the upper end of the slide 1, multiple The limiting rings 13 are respectively fixedly connected to the lower end of the sliding seat 11 and the square groove of the slide 1, and multiple springs 15 are respectively slidably connected to the multiple limiting rings 13. The two support rods 12 are fixedly connected to the square groove of the slide 1. The pressure plate 4 is slidably connected to the circumferential surface of the two support rods 12. The left end of the pressure plate 4 is fixedly connected to the right end of the sliding seat 11. This design solves the problem that the original device fixes the charging cable of the AC-DC battery charger and cannot protect the AC-DC battery. When the AC-DC battery is subjected to external collision, the AC-DC battery and the charger will become loose.

[0023] As the first embodiment of the present invention: the front and rear ends of the two slides 1 are fixedly connected with a slide bar 2, and the outer surface of each of the two slide bars 2 is slidably connected with a protective slide cover 5. The slide bars 2 installed at both ends of the slide 1 can make the protective slide cover 5 slide on the surface of the slide 1. The protective slide cover 5 sliding on the surface of the slide 1 can be used to protect the AC-DC battery. The upper ends of both sides of the two slides 1 are fixedly connected with a limit bar 3. The limit bar 3 installed on the slide 1 can make the AC-DC battery slide on the slide 1. The front and rear ends of the charger connection box 10 are rotatably connected to two swing frames 6. The upper circumferential surfaces of the two swing frames 6 are fixedly connected with a pressure tube 7. The swing frames 6 installed on both sides of the charger connection box 10 can drive the pressure tube 7 to swing up and down. The pressure tube 7 installed on the swing frame 6 can assist the sliding card seat 11 to fix the AC-DC battery. Anti-slip pads 14 are fixedly attached to the four corners of the lower end of the slide 1. These are made of rubber and serve to support the slide 1 and the insulated floor. The protective cover 5 is made of a transparent material, and the pressure tube 7 is made of an insulating material. The transparent material of the protective cover 5 allows the user to observe the AC-DC battery from the outside, while the pressure tube 7 is made of an insulating material, which secures the AC-DC battery while preventing it from interfering with the swing frame 6.

[0024] As a second embodiment of the present utility model: first, remove the protective slide cover 5, and then slide the AC-DC battery into the slide 1. The AC-DC battery presses the slide holder 11 so that the slide holder 11 slides into the square groove of the slide 1. However, after the charging part of the AC-DC battery is connected to the AC-DC battery charging head 8, the slide holder 11 is clamped by the elastic force of the spring 15 to fix the AC-DC battery. Then, move the swing frame 6 to fix the AC-DC battery. Finally, slide the protective slide cover 5 on the surface of the limit bar 3 so that the protective slide cover 5 clamps the pressure tube 7, and the AC-DC battery can be fixedly connected to the charger connection box 10. After charging the AC-DC battery, the protective slide cover 5 can be slid out, and then press the pressure plate 4 downward to release the slide holder 11 to release the AC-DC battery, and then the AC-DC battery can be taken out.
