[0059] The sealing barrel is further sealed by the arrangement of the first sealing ring 9 and the second sealing ring 10. The sealing ring can be a whole rubber ring or a rubber strip spliced ​​together.

[0060] In one implementation, the second sealing ring 10 is installed on the inside of the through hole by snapping; or, the second sealing ring 10 is installed on the outer edge of the through hole away from the barrel body 3, or, the second sealing ring 10 is snapped on the lower side of the sliding cover 1.

[0061] The second sealing ring 10 is clamped on the inside of the installation through hole to protect the through hole. The second sealing ring 10 can also be glued to the outer edge of the through hole on the side away from the barrel body 3.

[0062] In one implementation, the slide cover 1 is provided with a protruding portion 11, and a protruding or recessed strip structure 12 is provided on the protruding portion 11. In one implementation, the protruding portion 11 can be provided at any position of the head, middle or tail of the slide cover 1.

[0063] The protruding portion 11 is provided to facilitate pushing of the sliding cover 1 , and the protruding or recessed strip structure 12 on the protruding portion 11 is provided to increase the pushing friction of the protruding portion 11 .

[0064] In one implementation, the protrusion 11 may be a raised platform with a certain inclination angle, or the protrusion 11 may be a protruding column.

[0065] In one implementation, the through hole is provided at the first end of the mounting portion, a first slot 13 is provided at the first end of the mounting portion, and a first lug 14 that matches the slot is provided on the head of the sliding cover 1 .

[0066] In one implementation, the lug may be a sheet-like structure or a pin-like structure, and in order to better accommodate the lug, the first slot 13 may be a tapered structure with a gradually decreasing opening. The number of first lugs 14 may be one, two or three.

[0067] In one implementation, there is an extension portion at a position corresponding to the through hole below the slide cover 1, and the second sealing ring 10 is mounted and clamped on the extension portion on the lower side of the slide cover 1 to seal the through hole. The first lug 14 is provided on the extension portion, and the first lug 14 limits the second sealing ring 10 on the upper side of the first lug 14.

[0068] The first clamping groove 13 and the first lug 14 cooperate to limit the position of the head of the sliding cover 1, thereby preventing the sliding cover 1 from tilting and achieving sealing of the through hole.

[0069] In one implementation, a second slot 15 is disposed at the second end of the mounting portion, and a second lug 16 cooperating with the second slot 15 is disposed on the rear end of the sliding cover 1 .

[0070] The second slot 15 and the second lug 16 cooperate to limit the rear of the slide cover 1 and prevent the rear of the slide cover 1 from tilting. Similarly, the second slot 15 can also be a conical structure. The first lug 14 can be one, two or three.

[0071] In one implementation, two locking blocks 17 are relatively arranged on the upper surface of the mounting portion, and a locking column 18 cooperating with the locking blocks 17 is arranged on the lower surface of the sliding cover 1. When the sliding cover 1 slides to the first position, the locking column 18 slides between the locking blocks 17 and is locked by the locking cover.

[0072] In one implementation, the two locking blocks are plastic strips arranged in parallel, and the middle parts of the two plastic strips are recessed outward to form a space for accommodating the locking column 18. There is a certain elastic force between the two plastic strips. When the sliding cover slides closed, the locking column 18 opens the two plastic strips and enters the space in the plastic strips for accommodating the locking column 18, thereby locking the sliding cover.

[0073] The locking block 17 and the locking column 18 are provided to realize the locking and positioning of the sliding cover 1 after sealing, thereby preventing the sliding cover 1 from falling off.

[0074] In one implementation, two recessed portions 19 are symmetrically arranged on the barrel body 3 .

[0077] In one embodiment, the outer diameter of the fixing portion 2 is equal to the inner diameter of the barrel body 3. While preventing the fixing portion 2 from sinking into the barrel body, it also effectively increases the frictional force between the fixing cover 2 and the barrel body 3, facilitating the sealing between the fixing cover and the barrel body.

[0078] By setting the outer diameter of the fixing portion 2 to be less than or equal to the inner diameter of the barrel body 3, the jamming caused by the fixing cover 2 sinking inward is avoided.

[0079] In one implementation, as shown in the figure, the sliding seal barrel includes bumps 20 and spring clasps 21; the bumps are arranged in rows at intervals on the inner side of the lower edge of the sliding cover, and the spring clasps are arranged on the side surfaces where the fixing cover and the sliding cover are fitted and installed, and the spring clasps are used to insert between two adjacent bumps to position the sliding cover.

[0080] In one implementation, there are multiple bumps 20. The bumps 20 are arranged in a row along the sliding direction of the sliding cover on the inner side of the lower edge of the sliding cover. The spring clasp 21 is an elastic rod arranged on the outer side of the fixing cover. The end of the rod is provided with a protruding head. The rod itself has a certain elasticity, so it can drive the protruding head to protrude or retract to adapt to the movement of the sliding cover. When the sliding cover moves into place, the protruding head is stuck between two bumps to position the sliding cover at a specific position on the fixing cover.

[0081] In one implementation, in order to ensure the smooth relative movement between the sliding cover and the fixing cover, both the bumps and the protruding heads are set as arc surfaces or raised surfaces with rounded corners.

[0082] During the specific use process, hold the barrel body 3 firmly by grasping the recessed portion 19. First, open the fixing cover 2, pour the grains to be stored into the barrel body 3, and then install the fixing cover 2 onto the barrel body 3.

[0083] When taking out, by pushing the protruding portion 11 on the sliding cover 1, the locking column 18 is disengaged from the locking block 17, the sliding cover 1 is unlocked, the first lug 14 is withdrawn from the first card slot 13, and the second lug 16 is withdrawn from the second card slot 15. The sliding cover 1 slides relative to the fixing cover 2. The size of the opened through hole is determined by the limiting protrusion 8 on the sliding strip of the sliding cover 1 and the wave structure 7 on the slideway of the fixing cover 2, and then the grains are poured out.

[0084] After considering the specification and practicing the present invention, those skilled in the art will easily think of other implementation schemes of the present invention.
