[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] This embodiment provides a technical solution, such as Figures 1 to 6 As shown, an easy-tear cover for a milk powder can comprises a can body 1 and a sealing block 11 slidably connected to the can body 1, and a disassembly assembly 2 is arranged on the can body 1;

[0035] The unpacking assembly 2 includes a pressing member 21, a spring 23 is fixedly connected to the bottom of the pressing member 21, a sealing cover 4 is fixedly connected to the side of the spring 23 away from the pressing member 21, a first transmission member 24 is arranged at the bottom of the pressing member 21, a first rotating shaft 25 is fixedly connected to the side of the first transmission member 24 away from the pressing member 21, a second transmission member 26 is rotatably connected to the first rotating shaft 25, a triangular member 29 is fixedly connected to the side of the second transmission member 26 away from the fixed cylinder 22, and a rubber bump 41 is fixedly connected to the bottom of the sealing cover 4;

[0036] like Figure 1 , Figure 2 , Figure 5 As shown, in the utility model, by providing the unsealing assembly 2, the dual optimization of high sealing performance and easy opening is achieved. The pressing member 21, the spring 23, the sealing cover 4 and the interaction of the first transmission member 24 and the second transmission member 26 can start the unsealing assembly 2 by pressing with external force, so that the triangular member 29 is inserted between the rubber protrusion 41 and the can body 1, and the cover can be removed by rotating the fixing cylinder 22, which greatly reduces the force required for opening, making the operation easier and more convenient, and solving the problem that the prior art in the background technology is difficult to successfully tear open at one time;

[0037] A fixing cylinder 22 is slidably connected to the pressing member 21, and the fixing cylinder 22 is rotatably connected to the sealing cover 4. A fixing plate 27 is fixedly connected to the fixing cylinder 22, and the fixing plate 27 is slidably connected to the first transmission member 24. When in use, the pressing member 21 is pressed by external force, so that the first transmission member 24 drives the second transmission member 26 to move, and the first transmission member 24 slides out of the fixing cylinder 22, pushing the second transmission member 26 to rotate on the mounting plate 28, thereby realizing the transmission of the triangular member 29. The triangular member 29 is inserted between the rubber protrusion 41 and the tank body 1, and then the fixing cylinder 22 is rotated by external force to realize the removal of the easy-tear cover.

[0038] The second transmission member 26 is rotatably connected to the third rotating shaft 210, and the third rotating shaft 210 is rotatably connected to the mounting plate 28, which is rotatably connected to the sealing cover 4. By providing the third rotating shaft 210, a lever effect is achieved, so that the second transmission member 26 can drive the triangular member 29 to move, thereby realizing the removal of the easy-tear cover.

[0039] like Figures 1 to 4 As shown, a latch 33 is fixedly connected to the tank body 1, and a sliding groove is provided on the latch 33. A sliding block 32 is slidably connected in the sliding groove on the latch 33. By providing the latch 33, when in use, the pull rope 3 can be stuck by pressing down the sliding block 32, so that the sealing performance of the tank body 1 is better. During transportation, the sliding block 32 can be pulled out to release the pull rope 3, and the user can pull up the device through the pull rope 3, which is convenient for transportation.

[0040] like Figure 6 As shown, the blocking block 11 is fixedly connected with a fourth transmission member 54, a side of the fourth transmission member 54 away from the blocking block 11 is rotatably connected with a fifth shaft 53, a side of the fifth shaft 53 away from the fourth transmission member 54 is rotatably connected with a third transmission member 52, a side of the third transmission member 52 away from the fifth shaft 53 is rotatably connected with a fourth shaft 51, and a fixing member 5 is rotatably connected to the fourth shaft 51, and the fixing member 5 is fixedly connected to the tank body 1. By providing the fixing member 5, the rotatable connection of the blocking block 11 is realized, and the user can rotate the blocking block 11 by external force;

[0041] The above patents also have the problem of poor sealing and low portability of the device. Figure 6 As shown, a pulling rope 3 is provided on the sliding block 32, and both ends of the pulling rope 3 are rotatably connected to the fixed blocks 31, and the fixed block 31 is rotatably connected to the blocking block 11. By providing the fixed block 31 to connect the pulling rope 3 and fixing both ends of the pulling rope 3 on the blocking block 11, the sealing effect of the tank body 1 can be better when it is stationary, and the portable effect can be achieved during transportation.

[0042] Working principle:

[0043] like Figure 1-Figure 6As shown in the figure: when the user applies external force to the pressing member 21, the pressing member 21 is pressed down, and the spring 23 connected to the bottom of the pressing member 21 is compressed, which starts the operation of the entire unpacking assembly 2. As the pressing member 21 is pressed down, the first transmission member 24 pushes the second transmission member 26, and enables it to rotate relative to the fixed cylinder 22 through the first rotating shaft 25; this action drives the triangular member 29 to move and insert it between the rubber protrusion 41 and the can body 1, so that the rubber protrusion 41 is separated from the can body 1;

[0044] Subsequently, by rotating the fixing cylinder 22, complete removal of the cover is achieved;

[0045] The latch 33 and the sliding block 32 on the tank body 1 provide an additional locking function, enhance the sealing performance, and facilitate transportation. The blocking block 11 is connected to the tank body 1 through a complex rotation relationship to ensure flexible response to external forces. The pull rope 3 is designed to take into account both portability and sealing performance, optimizing the user experience. This design achieves a balance between high sealing performance and easy opening performance through sophisticated mechanical transmission and structural interlocking, improves the user experience, and ensures the safety and hygiene of the product.
