[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] like Figure 1-Figure 2 As shown, the present application provides a pull-ring tear strip cover for a plastic bucket, comprising a bucket body 1, and a handle 11 hinged to the bucket body 1, wherein the handle 11 is adapted to rotate on the bucket body 1 and lift the bucket body 1 by an external force;

[0024] A barrel cover 2 is provided at the top opening of the barrel body 1. The outer ring of the barrel cover 2 is provided with a flange, and a conflicting end 221 is provided on the inner wall of the flange of the barrel cover 2 and a buckling groove 22 is formed. A step 13 is provided on the outer edge of the opening of the barrel body 1, and a locking end 12 is formed on the barrel body 1 at the upper end of the step 13. The locking end 12 is adapted to the buckling groove 22 and forms a fitting structure, wherein the locking end 12 is suitable for being snapped into the buckling groove 22, and the conflicting end 221 conflicts with the step 13, thereby achieving a sealed cover between the barrel cover 2 and the barrel body 1;

[0025] At the same time, the center of the barrel cover 2 sinks toward its bottom and forms a raised end 21, and the raised end 21 is adapted to the opening of the barrel body 1, and a sealing strip 211 is fixed on the outer ring of the raised end 21. The sealing strip 211 is made of rubber material and can conflict with the inner wall of the barrel body 1 to seal the barrel body 1;

[0026] When the barrel cover 2 needs to be closed on the barrel body 1, the barrel cover 2 is first aligned with the opening of the barrel body 1, and then the barrel cover 2 is closed on the barrel body 1. During the process of closing the barrel cover 2 on the barrel body 1, the raised end 21 of the barrel cover 2 is first embedded in the inner barrel body 1, and the sealing strip 211 on the outer ring of the raised end 21 contacts the inner wall of the barrel body 1 to seal the barrel body 1 once, and then the locking end 12 is snapped into the locking groove 22, and the contact end 221 contacts the step 13 to seal the barrel body 1 twice, thereby achieving the purpose of multiple sealing between the barrel body 1 and the barrel cover 2;

[0027] like Figure 1 and Figure 3As shown, a pull rod unit 3 is provided between the barrel cover 2 and the barrel body 1. The pull rod unit 3 is used to fasten the barrel cover 2 to the barrel body 1. The pull rod unit 3 includes a pull ring 31 installed on the barrel cover 2 and a tear ring 33 installed on one side of the pull ring 31. The pull ring 31 is fixedly connected to the barrel cover 2, and the pull ring 31 is suitable for flipping on the barrel cover 2 to pull the barrel cover 2 away from the barrel body 1 through the pull ring 31.

[0028] At the same time, a tear strip 32 is fixedly connected to one side of the tear ring 33. The tear strip 32 is used to fix the barrel cover 2 to the barrel body 1, and the inner ring wall of the tear strip 32 conflicts with the barrel body 1. The tear strip 32 is installed around the bottom end of the barrel cover 2, and a tear seam (not shown in the figure) is provided between the tear strip 32 and the barrel cover 2, so that the tear strip 32 is suitable for tearing from the barrel cover 2. Break blocks 34 are provided between the end of the tear strip 32 and the pull ring 31, and between the pull ring 31 and the tear ring 33. The break blocks 34 are used for convenient separation.

[0029] When the lid 2 needs to be separated from the barrel body 1, a turning force is first applied to the pull ring 31 to separate the pull ring 31 from the tear strip 32 and the tear ring 33. Then, the tear ring 33 is pulled to pull the tear strip 32 along the tear seam, thereby loosening the lid 2 and the barrel body 1. Then, the pull ring 31 is turned over to deform the outer wall of the lid 2, thereby separating the locking end 12 from the buckling groove 22, thereby opening the barrel body 1.

[0030] To sum up, the opening of the barrel body 1 is covered by the raised end 21 on the barrel cover 2, and the barrel body 1 is sealed once with the cooperation of the sealing strip 211 against the inner wall of the barrel body 1. At the same time, the locking end 12 is engaged in the locking groove 22 to cover the barrel cover 2 on the barrel body 1, and under the mutual interference of the step 13 and the interference end 221, the barrel cover 2 and the barrel body 1 are sealed for a second time, thereby achieving the effect of multiple sealing between the barrel body 1 and the barrel cover 2.

[0031] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any improvements and modifications that fall within the spirit and principles of the present application and do not depart from the principles of the present application shall be deemed to be within the scope of protection of the present application.
