[0027] Reference Figure 1-Figure 7A fully automatic air-conditioning refrigerant charger comprises a mounting frame 1, on which a refrigerant tank 2 is arranged, and a fixed circular plate 3 is fixedly connected to the surface of the mounting frame 1, and further comprises: a turntable 4, which is rotatably connected in the fixed circular plate 3; a rotating drum 5, which is fixedly connected to the bottom of the turntable 4; a connecting plate 6, which is fixedly connected to the fixed circular plate 3, and a circular plate 7 is fixedly connected to the top of the connecting plate 6; a strip plate 8, which is slidably connected in the circular plate 7, and a first spring 9 is sleeved on the surface of the strip plate 8; an L-shaped plate 10, which is fixedly connected to the strip plate 8; a round rod 11, which is fixedly connected to the bottom of the strip plate 8; a driving The rod 12 is slidably connected in the rotating drum 5, and a driving block is fixedly connected to the surface of the driving rod 12. When the refrigerant tank 2 is installed, it contacts the driving rod 12. The driving rod 12 slides downward and contacts the inner wall of the spiral groove of the rotating drum 5 to rotate the rotating drum 5. The rotating drum 5 drives the turntable 4 to rotate. The arc-shaped hole on the surface of the turntable 4 causes the circular rod 11 to slide. The circular rod 11 drives the strip plate 8 to slide toward the inside of the disc 7, thereby driving the L-shaped plate 10 to clamp and support the refrigerant tank 2, thereby completing the installation and fixation of the refrigerant tank 2, which helps to prevent shaking and tipping and improve the stability of the refrigerant tank 2.

[0028] A circular groove is provided on the inner wall of the fixed circular plate 3, and the turntable 4 is rotatably connected to the circular groove of the fixed circular plate 3. When the turntable 4 rotates, the fixed circular plate 3 can support and limit the turntable 4, thereby preventing the turntable 4 from deflecting and making it rotate stably.

[0029] A spiral groove matched with the driving rod 12 is provided on the inner wall of the rotating drum 5. When the driving rod 12 is pressed downward by the refrigerant tank 2, the driving rod 12 enters the rotating drum 5 and contacts with the spiral groove of the rotating drum 5 to rotate the rotating drum 5, thereby driving the turntable 4 to rotate.

[0030] One end of the strip plate 8 away from the disc 7 is fixedly connected to the limit plate 13, one end of the first spring 9 is fixedly connected to the outer wall of the disc 7, and the other end of the first spring 9 is fixedly connected to the limit plate 13. The limit plate 13 can prevent the strip plate 8 from sliding too much into the disc 7, which helps to limit the strip plate 8. When the strip plate 8 slides into the disc 7, the first spring 9 can be compressed. The first spring 9 also helps to automatically reset the strip plate 8.

[0031] An arc-shaped hole is opened on the surface of the turntable 4, and the circular rod 11 passes through the arc-shaped hole of the turntable 4 and is slidably connected with the arc-shaped hole of the turntable 4. When the turntable 4 rotates, the arc-shaped hole can be driven to slide on the circular rod 11, so that the circular rod 11 slides along the arc-shaped hole of the turntable 4, thereby driving the strip plate 8 to slide and clamping and supporting the refrigerant tank 2.

[0032] A vertical plate 14 is fixedly connected to the bottom surface of the mounting frame 1, a horizontal plate 15 is fixedly connected to the left surface of the vertical plate 14, the driving rod 12 passes through the horizontal plate 15 and is slidably connected to the horizontal plate 15, and when the driving rod 12 slides downward, it can be supported by the horizontal plate 15, which helps to guide the driving rod 12.

[0033] A second spring 16 is sleeved on the bottom surface of the driving rod 12, one end of the second spring 16 is fixedly connected to the driving rod 12, and the other end of the second spring 16 is fixedly connected to the cross plate 15. When the driving rod 12 slides down, the second spring 16 can be compressed, and the second spring 16 helps to reset the driving rod 12 upward.

[0034] A slot is provided on the surface of the vertical plate 14, and an insertion rod 17 is passed through the bottom surface of the driving rod 12 and is slidably connected to the driving rod 12. The insertion rod 17 is slidably connected to the slot of the vertical plate 14, and a third spring 18 is sleeved on the surface of the insertion rod 17. One end of the third spring 18 is fixedly connected to the driving rod 12, and the other end of the third spring 18 is fixedly connected to the insertion rod 17. When the refrigerant tank 2 is fixed, the insertion rod 17 can be pulled to the left to disengage from the slot of the vertical plate 14, so that the driving rod 12 slides down. After the refrigerant tank 2 is fixed, the insertion rod 17 is released, and under the action of the third spring 18, the insertion rod 17 enters the slot of the vertical plate 14. The insertion rod 17 can support and limit the driving rod 12 to prevent the driving rod 12 from loosening, which helps to make the fixing effect of the refrigerant tank 2 more stable.

[0035] In the utility model, when the refrigerant tank 2 needs to be fixed, the insertion rod 17 is pulled to the left to disengage from the slot of the vertical plate 14, and the refrigerant tank 2 is placed in the disc 7 and the driving rod 12 is pressed downward. The driving rod 12 drives the driving block on the surface to contact the spiral groove of the rotating drum 5 to rotate the rotating drum 5, and the rotating drum 5 drives the turntable 4 to rotate. The arc-shaped hole on the surface of the turntable 4 is slidably connected with the circular rod 11 so that the circular rod 11 slides along the arc-shaped hole of the turntable 4, thereby driving the strip plate 8 to slide toward the inside of the disc 7, thereby driving the L-shaped plate 10 to clamp and fix the refrigerant tank 2, so that the refrigerant tank 2 is more stable when following the movement of the mounting frame 1, and then the insertion rod 17 is released on the third spring 1 8 enters the slot of the vertical plate 14 to limit the driving rod 12, thereby making the refrigerant tank 2 more stable. When the refrigerant tank 2 needs to be replaced, the insertion rod 17 is disengaged from the slot of the vertical plate 14 by pulling the insertion rod 17, and the driving rod 12 is reset under the action of the second spring 16. The driving block on the driving rod 12 contacts the inner wall of the rotating drum 5 to reverse the rotating drum 5, thereby driving the turntable 4 to reverse, so that the circular rod 11 slides in the opposite direction along the arc-shaped hole of the turntable 4, so that the circular rod 11 drives the strip plate 8 to slide outside the circular disk 7, and under the action of the first spring 9, the auxiliary strip plate 8 drives the L-shaped plate 10 to reset, so that the refrigerant tank 2 is no longer clamped and fixed, thereby facilitating the rapid replacement of the refrigerant tank 2.
