[0002] In the process of paint production, as a common storage tool, the design and function of the packaging barrel are crucial for improving construction efficiency, ensuring paint quality, and enhancing user experience. Although the traditional packaging barrel has a simple shape, it is prone to being distorted and deformed by external forces during construction, which limits the use of paint and brings inconvenience to construction.

[0003] In different fields and daily life, packaging barrels not only play an important role in industrial production and construction, but also demonstrate their versatility in aspects such as artistic creation, daily life, and environmental protection and recycling. When selecting and using a packaging barrel, its material, capacity, sealing performance, and applicable occasions should be considered to ensure its safe and efficient use;

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0027] A packaging barrel with high sealing performance, including a barrel body 1, the upper end of the barrel body 1 is movably connected with a barrel cover 2, a circular groove 21 is opened at the upper end of the barrel cover 2, and a clamping assembly 3 is respectively arranged at the upper end of the circular groove 21 and inside the barrel cover 2. The clamping assembly 3 includes a circular cavity 33 opened inside the barrel cover 2. The number of the circular cavities 33 is four. A circular rod 331 is movably connected inside the plurality of circular cavities 33. First sliders 332 are fixedly connected to the mutually remote ends of the circular rod 331. A second spring 333 is movably connected to the outer part of the circular rod 331. Connecting grooves 34 are opened at the lower ends of the plurality of circular cavities 33. The clamping assembly 3 further includes an airbag 31 fixedly connected to the upper end of the circular groove 21. A first spring 311 is movably connected inside the airbag 31. Connecting pipes 32 are fixedly connected between the airbag 31 and the plurality of connecting grooves 34. A caster 11 is fixedly connected to the lower end of the barrel body 1. A groove 12 is opened on the outer part of the caster 11. The width of the groove 12 is greater than the diameter of the circular rod 331. The elastic force of the first spring 311 is greater than the gravity of the airbag 31. The elastic force of the second spring 333 is greater than the sum of the elastic forces of the circular rod 331 and the first slider 332.

[0028] By adopting the above technical solution, after injecting paint into the barrel body 1, the barrel cover 2 is fixed to the upper end of the barrel body 1. When transportation is needed, first place the barrel body 1 at a designated position, and then place other barrel bodies 1 on the airbag 31 at the upper end of the circular groove 21. The airbag 31 and the first spring 311 inside are forced to move downward. As the volume inside the airbag 31 decreases, the gas inside the airbag 31 is continuously compressed and moves through the connecting pipe 32 into the connecting groove 34, and then enters the circular cavity 33 by squeezing the gas inside the connecting groove 34. The gas inside the circular cavity 33 pushes the first slider 332 to move towards the inside of the circular groove 21, thereby compressing the second spring 333 and driving the circular rod 331 to move towards the inside of the circular groove 21, so that the circular rod 331 moves into the groove 12 inside the caster 11, thereby strengthening the upper barrel body 1, so as to achieve the purpose of clamping and fixing the upper packaging barrel by stacking and piling up when stacking and transporting the packaging barrels, to avoid the packaging barrels from toppling due to unstable center of gravity caused by insufficient firmness during transportation, and further ensure the quality of the packaging barrels.

[0029] Specifically, such as Figure 4As shown in the figure, a scraping component 4 is arranged at the lower end of the bucket cover 2. The scraping component 4 includes a connecting plate 41 fixedly connected to the lower end of the bucket cover 2. The number of the connecting plates 41 is two. Slide grooves 411 are formed in the exteriors of the two connecting plates 41. Second sliders 421 are movably connected to the interiors of the two slide grooves 411. Fixed rods 42 are fixedly connected to the front and rear ends of each of the second sliders 421. A scraping plate 43 is fixedly connected to the lower ends of adjacent two of the fixed rods 42. A disc 44 is fixedly connected to the lower ends of the two scraping plates 43. The second sliders 421 are slidably attached to the interiors of the slide grooves 411, and the two scraping plates 43 are slidably attached to the inner wall of the bucket body 1.

[0030] By adopting the above technical solution, after the paint inside the packaging bucket is consumed and there is still paint remaining on the inner wall of the bucket body 1, at this time, the bucket cover 2 is moved upward. The upward movement of the bucket cover 2 drives the two connecting plates 41 at the lower end to move upward together. The upward movement of the connecting plate 41 causes the second slider 421 between the fixed rods 42 to slide inside the slide groove 411. When the second slider 421 reaches the lowermost end inside the slide groove 411, at this time, the bucket cover 2 is rotated. The rotation of the bucket cover 2 drives the connecting plate 41 at the lower end and the fixed rods 42 and the second slider 421 at the lower end to rotate together. The rotation of the fixed rod 42 drives the scraping plate 43 at the lower end to rotate. The scraping plate 43 rotates and continuously scrapes the inner wall of the bucket body 1. The paint remaining on the inner wall of the bucket body 1 falls into the interior of the disc 44 under the influence of gravity through the scraping plate 43. Then, the disc 44 is pulled out upward, and finally the paint inside the disc 44 is used. Thus, after the paint inside the packaging bucket is consumed, the purpose of scraping the inner wall of the bucket by rotating the bucket cover 2 is achieved, thereby avoiding the loss of the paint inside the bucket.

[0031] Working principle: After the paint is injected into the interior of the bucket body 1, the bucket cover 2 is fixed to the upper end of the bucket body 1. When transportation is required, first, the bucket body 1 is placed at a designated position. Secondly, other bucket bodies 1 are placed on the airbag 31 at the upper end of the circular groove 21. The airbag 31 and the first spring 311 inside are forced to move downward. As the volume inside the airbag 31 decreases, the gas inside the airbag 31 is continuously compressed and moves through the connecting pipe 32 into the connecting groove 34, and then the gas inside the connecting groove 34 is squeezed into the circular cavity 33. The gas inside the circular cavity 33 pushes the first slider 332 to move into the circular groove 21, thereby compressing the second spring 333 and driving the round rod 331 to move into the circular groove 21, so that the round rod 331 moves into the groove 12 inside the caster wheel 11, thereby reinforcing the upper bucket body 1. To achieve the purpose of clamping and fixing the upper packaging bucket by stacking and piling up when stacking and transporting the packaging buckets, to avoid the packaging bucket from toppling due to unstable center of gravity during transportation due to insufficient firm packaging, thereby ensuring the quality of the packaging bucket.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
