[0030] Refer to the attached Figure 1-5 , a metal barrel top cover sealing structure, comprising:

[0031] The first cover plate 2 is located at the top of the barrel body 1 and has a flange plate 3 on its side wall; a plurality of limit plates 4 are provided on the flange plate 3, and a limit block 5 is provided below the side wall of the limit plate 4; a positioning plate 8 is provided on the top of the limit plate 4, and a positioning hole 9 is provided on the positioning plate 8; a limit groove 6 is provided on the top of the side wall of the barrel body 1; a clamping groove 7 that cooperates with the limit block 5 is provided below the side wall of the limit groove 6. When the limit block 5 enters the clamping groove 7, the first cover plate 2 and the barrel body 1 can be limited.

[0032] The second cover plate 10 is located above the flange plate 3 and has a plurality of second limiting plates 11 at its bottom. A second limiting block 12 is provided on one side of the bottom of the second limiting plate 11. The second limiting block 12 is located within the limiting groove 6 and abuts against the side of the limiting plate 4 away from the limiting block 5, thereby preventing the limiting block 5 from moving freely within the limiting groove 6. The spacing between the plurality of second limiting plates 11 corresponds to the position of the top horizontal plate of the limiting plate 4.

[0033] The third cover plate 13 is located on the top of the first cover plate 2, and a plurality of limit plates 3 14 are provided at the bottom of the top plate; a positioning column 15 is provided on one side of the limit plate 3 14 and cooperates with the positioning hole 9 at the corresponding position, which can connect the third cover plate 13 with the first cover plate 2 for limiting, and the bottom of the limit plate 3 14 can also squeeze the upper surface of the second cover plate 10 to prevent the limit block 2 12 from falling out of the limit groove 6.

[0034] In this embodiment, a plurality of avoidance grooves 20 are further provided on the second cover plate 10 , and the positioning plate 8 passes through the avoidance grooves 20 at corresponding positions, and ensures that the height of the positioning hole 9 is higher than the height of the first cover plate 2 , so that the subsequent positioning column 15 can smoothly enter the positioning hole 9 .

[0035] A first sealing rubber ring 16 is provided below flange plate 1 3 , the bottom of which abuts the top of barrel body 1 . Flange plate 2 17 is provided on the inner wall of barrel body 1 , and a second sealing rubber ring 18 is provided above flange plate 2 17 ; second sealing rubber ring 18 abuts the bottom of first cover plate 2 . By placing two sealing rubber rings in two different locations, a double-layer seal is achieved, improving the sealing effect.

[0036] It should be noted that flange plate 1 (3) is provided with multiple notches 19 corresponding in size and position to retaining grooves 6. Retaining plate 1 (4) is positioned within these notches 19, with its top horizontal plate secured to flange plate 1 (3) via bolts. When first cover plate 2 is placed on barrel body 1, the vertical plates of retaining plate 1 (4) pass downward through notches 19 and into the corresponding retaining grooves 6. Rotating first cover plate 2 allows retaining blocks 1 (5) on the lower sidewalls of the retaining plate to enter retaining grooves 7. At this point, retaining blocks 1 (5) engage with retaining grooves 7 to initially retain first cover plate 2, preventing it from separating from barrel body 1.

[0037] When the first cover plate 2 is placed on the flange plate 1 3 of the first cover plate 2, the second stopper 12 below the second stopper 11 enters the stopper groove 6, filling the stopper groove 6 and leaving no room for the first stopper 5 to move. At this point, one side of the second stopper 12 abuts against the side of the stopper groove 6, while the other side abuts against the side of the first stopper 4 away from the first stopper 5. While the first cover plate 2 is now fixed in place, the second cover plate 10 may still be pulled upward away from the barrel body 1 under external force. To this end, the third cover plate 13 further secures the second cover plate 10.

[0038] Two handles 21 are provided on the top of the third cover plate 13, and its side walls are threadedly engaged with the top of the barrel body 1. The third cover plate 13 is placed on top of the first cover plate 2 using the handles 21 and slowly lowered. Threads are provided on the top of the outer wall of the barrel body 1. When the third cover plate 13 is lowered to a specific height and contacts the threads on the barrel body 1, the staff can rotate the third cover plate 13 by holding the handles 21 until the positioning posts 15 on the limiting plate 3 14 inside the third cover plate 13 enter the positioning holes 9 at the corresponding positions. At this time, the bottom of the limiting plate 3 14 rests on the upper surface of the second cover plate 10, preventing the second cover plate 10 from separating from the flange plate 1 3. Since there is a threaded engagement area between the third cover plate 13 and the barrel body 1, and the positioning posts 15 and the positioning holes 9 are limited, the third cover plate 13 can be prevented from separating from the barrel body 1.

[0039] The metal barrel top cover sealing structure of the present invention can completely cover the various components used for sealing and limiting by arranging a first cover plate 2, a second cover plate 10 and a third cover plate 13 that cooperate with each other on the barrel body 1, thereby solving the problem in the prior art that many components are exposed to the outside of the barrel body 1 and the top cover, affecting the appearance and transportation. At the same time, it can also avoid the top cover from falling off due to bumps during transportation, which affects the sealing effect. The utility model is very practical and has good market application prospects.
