[0023] An embodiment of the present utility model discloses a metal can that is easy to open.

[0024] The present utility model provides a metal can that is easy to open as Figures 1-4 shown, including a tank body 1, a metal cover 2 and a sealing plate 3. A first sealing ring 4 is fixedly installed inside the tank body 1. A sealing groove 5 is provided on the top surface of the tank body 1. A sealing plate 3 is fixedly installed at the bottom of the metal cover 2. The size of the sealing plate 3 matches the size inside the first sealing ring 4. A second sealing ring 6 is fixedly installed at the bottom of the metal cover 2. The size of the second sealing ring 6 matches the size inside the sealing groove 5, and the second sealing ring 6 is slidably connected to the sealing groove 5. The top of the metal cover 2 is hinged with a cover plate 7 through a hinge. An installation groove 8 is provided on the surface of the metal cover 2 at the bottom of the cover plate 7. A rotating disc 9 is fixedly installed inside the installation groove 8, which can make the metal can be better sealed.

[0025] The utility model relates to a metal can which is convenient to open. A rotating shaft 10 is fixedly installed at the bottom of a rotating disc 9. An installation cylinder 11 is slidably installed at the bottom of the rotating shaft 10. Both the installation cylinder 11 and the rotating shaft 10 are rotatably connected to a sealing plate 3. The bottom of the installation cylinder 11 penetrates through the sealing plate 3 and extends out of the bottom of the sealing plate 3. Baffles 12 are fixedly installed on both sides of the bottom of the sealing plate 3. Limiting cylinders 13 are fixedly installed on the surfaces of the sealing plate 3 on both sides of the two baffles 12. Limiting columns 14 are slidably connected inside the two limiting cylinders 13. Pulling ropes 15 are fixedly installed on both sides of the installation cylinder 11. The two pulling ropes 15 are wound around the surface of the installation cylinder 11. The other ends of the two pulling ropes 15 are fixedly connected to one end of one baffle 12 and the limiting column 14 respectively. Return springs 16 are fixedly installed on one side of the two baffles 12. The two return springs 16 are respectively sleeved on the surfaces of the two pulling ropes 15. The other ends of the two return springs 16 are fixedly installed on one side of the two limiting columns 14 respectively. A plurality of clamping grooves 17 are arranged on the inner surface of the first sealing ring 4. The two limiting columns 14 are respectively matched with the sizes of the plurality of clamping grooves 17 and are slidably connected to the plurality of clamping grooves 17, which is convenient for quickly packaging and disassembling the metal can.

[0026] When in use, place the metal cover 2 and the sealing plate 3 on the top of the can body 1, make the sealing plate 3 be clamped with the first sealing ring 4, and at the same time make the second sealing ring 6 be clamped with the sealing groove 5. Then open the cover plate 7, pull the rotating disc 9, pull the rotating disc 9 out of the installation groove 8, and then rotate the rotating disc 9. The rotating disc 9 drives the installation cylinder 11 to rotate through the rotating shaft 10. The installation cylinder 11 will release the pulling ropes 15. The two return springs 16 will push the limiting columns 14 into the clamping grooves 17. Then press the rotating disc 9 into the installation groove 8. If it is necessary to open the metal can, only need to pull out the rotating disc 9 and then reverse the rotating disc 9. The rotating disc 9 will drive the installation cylinder 11 to reverse through the rotating shaft 10. The installation cylinder 11 will retract the pulling ropes 15. The pulling ropes 15 will pull the limiting columns 14 out of the clamping grooves 17. Then the metal cover 2 can be removed.
