Description

Technical Field

[0001] This utility model relates to the field of tank dust prevention technology, specifically a dust cover assembly structure for tanks. Background Technology

[0002] Aluminum cans are lightweight, airtight metal packaging containers primarily made of aluminum alloy. Their core value lies in their easy-open design and robust materials, providing excellent portability, shelf-life protection, and pressure resistance for beverages such as beer and carbonated drinks. They not only effectively block light and oxygen to maintain the flavor and freshness of the contents, but their metal material also offers the environmental advantage of efficient recycling and reuse. In addition, their compact stacking design reduces logistics costs, making them one of the mainstream packaging forms in the global beverage industry.

[0003] In the existing technology, once the pull tab of an aluminum can is pulled open, the opening of the can is always exposed to the external environment. When the beverage inside the can cannot be consumed in a short time, dust and other contaminants can easily enter the can, which will not only affect the hygiene and taste of the beverage, but also shorten the shelf life of the remaining beverage.

[0004] Therefore, this utility model provides a dust cover assembly structure for a tank to solve the above problems. Summary of the Invention

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a dust cover assembly structure for a tank, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a base 1, a partition 2 fixedly connected to the top of the base 1, a protective shell 3 fixedly connected to the top of the partition 2, a mounting base 4 fixedly connected to the top of the protective shell 3, a cover 5 fixedly connected to the top of the mounting base 4, a rotating shell 6 rotatably connected to the top of the cover 5, a toothed groove on the bottom of the rotating shell 6, a sliding groove 8 on the mounting base 4, a clamping assembly on the mounting base 4, and a stabilizing assembly on the top of the partition 2 and inside the base 1.

[0019] The clamping assembly includes a slide plate 9, which is slidably connected inside the slide groove 8. A connecting rod 10 is fixedly connected to the bottom of the slide plate 9. The end of the connecting rod 10 away from the slide plate 9 extends into the interior of the protective shell 3 and is fixedly connected to a clamping plate 11. A rotating ring 7 is rotatably connected inside the mounting base 4. A traction groove 13 is provided on the rotating ring 7. A traction column 12 is fixedly connected to the top of the slide plate 9 and is inserted into the interior of the traction groove 13.

[0020] The inner wall of the rotating shell 6 is rotatably attached to the side surfaces of the cover 5 and the mounting base 4 respectively. The side surface of the rotating ring 7 is provided with protrusions. The rotating ring 7 is fixedly connected to the inner wall of the rotating shell 6 through the protrusions. The top of the rotating ring 7 is rotatably attached to the bottom of the cover 5.

[0021] The cover 5 is internally connected to a gasket 22, the outer wall of the rotating shell 6 is provided with a strip groove, the top of the clamping plate 11 slides against the bottom of the mounting base 4, and the bottom of the clamping plate 11 slides against the top of the partition 2.

[0022] The gasket 22 inside the cover 5 is replaceable. When protecting the can, the dust cover can be directly placed on the can. After the cover is placed, the top of the can contacts the gasket 22. Then, the user needs to rotate the rotating shell 6. The groove on the rotating shell 6 can effectively increase the friction between the user and the hand, so that the user can rotate the rotating shell 6. When the rotating shell 6 rotates, it can drive the rotating ring 7 to rotate. When the rotating ring 7 rotates, the inner wall of the traction groove 13 can squeeze the traction column 12. The squeezed traction column 12 can drive the slide plate 9 to move inside the slide groove 8. When the slide plate 9 moves, it can drive the clamp 11 to approach the can through the connecting rod 10. The movement of the clamp 11 makes the dust cover suitable for cans of different sizes. The inner wall of the clamp 11 is provided with an anti-slip pad. When the anti-slip pad on the clamp 11 is in close contact with the can, the rotating shell 6 can be released. At this time, the dust cover forms a stable connection with the can through the clamp 11, effectively reducing the possibility of dust entering the can.

[0023] Furthermore, in order to improve the stability of the rotating shell 6, such as Figure 2 , Figure 4 and Figure 6 As shown, the stabilizing component includes a pressure plate 15, which is slidably connected inside the base 1. A through groove 16 is provided on the base 1, and the pressure plate 15 extends to the outside of the base 1 through the through groove 16. A first spring 14 is fixedly connected to the bottom of the pressure plate 15, and the bottom end of the first spring 14 is fixedly connected to the bottom inner wall of the base 1.

[0024] The stabilizing assembly also includes a connecting post 18, the bottom end of which is fixedly connected to the top of the pressure plate 15. The connecting post 18 passes through the partition 2. A toothed plate 17 is fixedly connected to the top of the connecting post 18, and a second spring 19 is fixedly connected to the bottom of the toothed plate 17.

[0025] The bottom end of the second spring 19 is fixedly connected to the top of the partition 2. The toothed plate 17 engages with the toothed groove. The protective shell 3 is provided with a groove 23. The side surface of the toothed plate 17 slides against the inner wall of the groove 23.

[0026] When the user rotates the rotating shell 6, they need to press the pressure plate 15 first. When the pressure plate 15 slides inside the base 1, it can compress the first spring 14 and simultaneously drive the connecting column 18 to move down. When the connecting column 18 moves down, it can drive the toothed plate 17 to move down. When the toothed plate 17 moves down, it can separate from the toothed groove at the bottom of the rotating shell 6 and simultaneously compress the second spring 19. After the toothed plate 17 separates from the toothed groove, the rotating shell 6 is no longer restricted. At this time, the user can rotate the rotating shell 6. When the rotating shell 6 is rotated to the appropriate position, the pressure plate 15 can be released. Then the first spring 14 and the second spring 19 will release pressure at the same time and push the pressure plate 15 and the toothed plate 17 to reset. After the toothed plate 17 resets, it can re-engage with the toothed groove, thereby fixing the rotating shell 6 and effectively improving the stability of the rotating shell 6.

[0027] In order to improve the stability of the clamping plate 11 during movement, such as Figure 2 , Figure 3 and Figure 5 As shown, a slide cylinder 20 is fixedly connected to the inner wall of the protective shell 3, and a slide rod 21 is slidably connected inside the slide cylinder 20. One end of the slide rod 21 is fixedly connected to the side of the clamping plate 11 near the connecting rod 10.

[0028] When the clamping plate 11 moves under the drive of the connecting rod 10, the sliding rod 21 will slide synchronously inside the sliding cylinder 20. Since the sliding cylinder 20 is fixed on the inner wall of the protective shell 3, the cooperation between the sliding rod 21 and the sliding cylinder 20 can provide a stable guiding effect for the clamping plate 11, ensuring that the clamping plate 11 will not deviate or shake during the movement, thereby improving the stability of the clamping plate 11.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
