[0019] like Figure 1 to Figure 6As shown, a convenient locking structure for a barrel cover of a plastic barrel comprises a plastic barrel body 1, a barrel cover 2, an annular fastener and a locking assembly 3. The barrel cover 2 is arranged at the top of the barrel mouth of the plastic barrel body 1, and the inner side wall of the barrel cover 2 is plugged into and contacted with the outer side wall of the barrel mouth of the plastic barrel body 1 for assembly connection. At least one annular sealing groove 9 is provided at the top of the barrel mouth of the plastic barrel body 1, and an annular sealing ring 10 is embedded in each annular sealing groove 9. An annular boss 11 is fixedly provided on the inner bottom surface of the barrel cover 2 at the position of the annular sealing groove 9, and the annular boss 11 is adapted to the shape of the annular sealing groove 9. When the barrel cover 2 and the plastic barrel body 1 are assembled and connected, the annular boss 11 is inserted into the annular sealing groove 9 and The annular sealing ring 10 is squeezed at the bottom of the annular boss 11. The annular boss 11 is matched with the annular sealing groove 9 and the annular sealing ring 10 arranged therebetween can ensure the sealing between the barrel cover 2 and the barrel mouth of the plastic barrel body 1; an annular receiving groove 4 is opened on the inner side wall of the barrel cover 2 along its circumference, and a circle of sealing cushion 5 is fixedly arranged at the edge of the annular receiving groove 4 close to the inner side wall of the barrel cover 2. The sealing cushion 5 is made of rubber material and can ensure good elastic deformation and sealing performance; an annular fastener is arranged in the annular receiving groove 4, and the annular fastener is a fastening clamp 7. The annular hoop body 71 of the fastening clamp 7 is arranged in the annular receiving groove 4, and the annular receiving groove 4 and the barrel cover 2 are fixedly arranged at the edge of the annular receiving groove 4 close to the inner side wall of the barrel cover 2. A connecting port 6 is provided between the outer walls, a bolt fastening head 72 of a fastening clamp 7 extends from the connecting port 6 to the outside of the barrel cover 2, and an annular fastening groove 8 is provided on the outer wall of the plastic barrel body 1 at the position of the annular accommodating groove 4. When the bolt fastening head 72 of the fastening clamp 7 is tightened, the annular hoop body 71 of the fastening clamp 7 is tightened and squeezed into the annular fastening groove 8, and the sealing gasket 5 is in close contact with the bottom of the annular fastening groove 8, which can further improve the sealing performance between the barrel cover 2 and the barrel mouth of the plastic barrel body 1; the barrel cover 2 and the plastic barrel body 1 are fixedly connected by a locking assembly 3, specifically, the locking assembly 3 includes a hook 31, a hanging ring 32 and a rotating handle 33, and the barrel cover 2 A plurality of hooks 31 are fixedly provided at the outer bottom at uniform intervals along its circumference, a rotating handle 33 is provided on the outer wall of the plastic barrel body 1 at the position corresponding to each hook 31, and each rotating handle 33 is hinged to the outer wall of the plastic barrel body 1 through a fixed support, a hanging ring 32 is rotatably provided on each rotating handle 33, and the rotating point of the hanging ring 32 is located below the hinge point of the rotating handle 33. When the barrel cover 2 and the plastic barrel body 1 are assembled and connected, the positions of the plurality of hooks 31 correspond to the positions of the plurality of hanging rings 32 one by one, the hanging ring 32 is hung on the corresponding hook 31 by lifting the rotating handle 33 upwards, and the rotating handle 33 is pressed downwards so that the hanging ring 32 pulls the hook 31 downwards.

[0020] In summary, it can be seen that by setting the fastening clamp 7 between the barrel cover 2 and the barrel mouth of the plastic barrel body 1 and the setting of the hook 31, the hanging ring 32 and the rotating handle 33 in the locking assembly 3, when the barrel cover 2 is locked with the barrel mouth of the plastic barrel body 1, the barrel cover 2 is placed on the top of the barrel mouth of the plastic barrel body 1, so that the annular boss 11 on the barrel cover 2 is clamped in the annular sealing groove 9 at the barrel mouth of the plastic barrel body 1, and the annular sealing ring 10 is embedded in the annular sealing groove 9. At this time, the hook 31 at the bottom of the barrel cover 2 corresponds to the hanging ring 32 on the outer wall of the plastic barrel body 1, and then the rotating handle 33 is lifted upward to hang the hanging ring 32 on the corresponding hook 31, and the rotating handle is pressed downward. The handle 33 allows the hanging ring 32 to pull the hook 31 downward, thereby driving the annular boss 11 on the barrel cover 2 to press the annular sealing ring 10 in the annular sealing groove 9 to ensure the sealing between the barrel cover 2 and the barrel mouth of the plastic barrel body 1, and then tighten the bolt fastening head 72 of the fastening clamp 7, thereby making the annular hoop body 71 of the fastening clamp 7 tighten and squeeze the sealing gasket 5 into the annular fastening groove 8, so that the sealing gasket 5 is in close contact with the bottom of the annular fastening groove 8, thereby further improving the sealing performance between the barrel cover 2 and the barrel mouth of the plastic barrel body 1, and the combined use of the locking assembly 3 and the fastening clamp 7 can enhance the stability of the axial connection between the barrel cover 2 and the plastic barrel body 1.
