Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-6The utility model provides a technical solution: a stretchable packaging can, including a can body 1 and a cover body 2, an inner tube 3 is provided inside the can body 1, the inner tube 3 is located in the can body 1 and slides up and down, the outer side of the inner tube 3 is fixedly connected with a threaded limiting plate 4, the outer side of the threaded limiting plate 4 is threadedly connected with a fixing button 5, the outer wall of the can body 1 is provided with a limiting card groove 8, the inner lower end of the threaded limiting plate 4 is fixedly connected with a card strip 9, the card strip 9 is matched with the limiting card groove 8 and is clamped, the upper edge of the can body 1 is provided with a sealing mechanism, and the sealing mechanism is provided between the can body 1 and the threaded limiting plate 4; the can body 1 and the cover The body 2 is arranged in an upper and lower sleeve manner, and an inner tube 3 is arranged in the tank body 1. The inner tube 3 moves up and down inside, and the overall internal space of the tank body 1 can be increased through the inner tube 3. A threaded limiting plate 4 is fixedly connected to the outer end of the inner tube 3. The threaded limiting plate 4 is divided into three parts. The threaded limiting plate 4 itself is tilted to the outside, and under the rotation action of the fixing button 5, it is moved inward and clamped, and then the clip 9 on the inner wall of the lower end of the threaded limiting plate 4 is clamped and fixed with the limiting slot 8 opened on the outside of the tank body 1, so that the inner tube 3 can be stably fixed in the required position, so that the internal space can be stably utilized.
[0021] like Figure 5 The sealing strip 11 is fixedly connected to the upper end of the tank body 1 with a fixing ring 10, and the inner and outer sides of the fixing ring 10 are slidingly opposed to the outer wall of the inner cylinder 3 and the inner wall of the threaded limiting plate 4, and the sealing strip 11 is fixedly connected to the upper end of the fixing ring 10; the gasket 12 is fixedly connected to the outer wall of the fixing ring 10, the gasket 12 is hollow, and the outer wall of the gasket 12 is opposed to the inner wall of the threaded limiting plate 4; the inner cylinder 3 and the threaded limiting plate 4 contact the two side edges of the sealing strip 11 during the up and down movement, and the two side edges of the sealing strip 11 bend as the inner cylinder 3 and the threaded limiting plate 4 move up and down, thereby achieving a sealing effect, and the gasket 12 is opposed to the inner wall of the threaded limiting plate 4, playing a two-layer sealing effect, thereby preventing air leakage at the connection between the inner cylinder 3 and the tank body 1 and preventing dust from entering.
[0022] like Figure 3 As shown, the outer wall of the upper end of the threaded limiting plate 4 is fixedly connected with a retaining ring 6, and the upper end face of the retaining ring 6 is fixedly connected with a sealing gasket, which is set against the lower end face of the cover body 2; the retaining ring 6 limits the fixed position of the cover body 2, and the upper end of the retaining ring 6 fixes the sealing gasket, which is in contact with the lower end face of the cover body 2 through the sealing gasket, thereby achieving a sealing effect.
[0023] like Figure 3As shown in the figure, a handle 7 is fixedly connected to the upper end of the cover body 2. The handle 7 is arranged across the upper end of the cover body 2 and is rectangular. The handle 7 is fixed to the upper end of the cover body 2, so that there is enough space when taking the cover body 2 through the handle 7, and the contact area with the operator's hand can be increased, improving the comfort of use.
[0024] As Figure 6 shown in the figure, the clamping strips 9 are distributed at the upper and lower ends, and the clamping strips 9 are arranged in two adjacent limit clamping grooves 8; the clamping strips 9 are distributed at the upper and lower ends, and through the two clamping strips 9, the threaded limit plate 4 can be stably clamped with the limit clamping groove 8, thereby improving the stability of fixation.
