Description

Technical Field

[0001] This utility model relates to the field of packaging plastic bucket technology, specifically a packaging plastic bucket with variable volume. Background Technology

[0002] Packaging plastic drums are containers made of plastic materials such as polyethylene (PE) and polypropylene (PP), typically used for storing and transporting liquids or solids. They are lightweight, corrosion-resistant, moisture-proof, and have good sealing properties, making them widely used in the chemical, food, and pharmaceutical industries. The capacity of plastic drums ranges from a few liters to tens of liters, and some products can be customized in color, shape, and additional functions (such as UV protection and stacking design). Existing packaging plastic drums mostly consist of a drum body, a lid, and a handle. The lid is threaded to the top of the drum body, providing a certain degree of sealing. The handle is used for moving the drum body. In practical applications, traditional packaging plastic drums have fixed dimensions; the designed volume is the same as the actual volume used, preventing adjustments based on actual conditions and resulting in poor flexibility. Therefore, we propose a packaging plastic drum with variable capacity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multi-volume packaging plastic bucket with a connecting mechanism and a segmented design, which can quickly connect bucket body one, bucket body two, and bucket body three. In practical applications, the volume of the packaging plastic bucket can be changed by increasing or decreasing the number of bucket bodies two, which is highly flexible and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a variable-volume packaging plastic bucket, comprising a bucket body and a connecting mechanism;

[0005] Barrel body one: Barrel body two is provided at its upper end, and barrel body three is provided at the upper end of barrel body two;

[0006] The connecting mechanism includes limiting grooves, limiting heads, limiting posts, and limiting holes. The limiting grooves are all located at the upper ends of barrel one and barrel two, and the limiting heads are all located at the lower ends of barrel two and barrel three. The outer surfaces of the limiting heads on both the front and rear sides are slidably connected to the inner walls of the laterally adjacent limiting grooves. Limiting posts are provided inside the limiting grooves on both the front and rear sides, and limiting holes are provided in the middle of the inner surfaces of the limiting heads on both the front and rear sides. The outer surfaces of the limiting posts are slidably connected to the inner walls of the laterally adjacent limiting holes. This provides a basis for the rapid connection of barrel one, barrel two, and barrel three. The connecting mechanism adopts a segmented design, allowing for the rapid connection of barrel one, barrel two, and barrel three. In practical applications, the volume of the packaging plastic barrel can be changed by increasing or decreasing the number of barrel twos, offering high flexibility.

[0007] Furthermore, the connecting mechanism also includes connecting holes and hexagon socket head cap screws. Connecting holes are provided in the middle of the interior of the limiting heads on both the left and right sides. Hexagon socket head cap screws are threaded to the upper left and right sides of the upper middle of the outer surface of barrel one and barrel two. The middle of the outer surface of the hexagon socket head cap screws are threaded to the inner wall of the connecting holes that are longitudinally adjacent. The limiting of the hexagon socket head cap screws can prevent loosening and misalignment between the barrels.

[0008] Furthermore, the connecting mechanism also includes a sealing assembly, which includes a sealing strip, a slot, and a plug ring. The slots are all located at the inner edge of the upper end of barrel one and barrel two. The sealing strips are all located in the middle of the bottom wall of the slots. The plug rings are all located at the inner edge of the lower end of barrel two and barrel three. The outer surface of the plug rings is inserted into the inner wall of the horizontally adjacent slots. The lower end of the plug rings is abutted against the upper end of the horizontally adjacent sealing strips, providing a basis for sealing between barrels.

[0009] Furthermore, the connecting mechanism also includes a notch, which is opened inside the limiting groove on the side away from the limiting post. The inner wall of the notch is fitted with the inner wall of the laterally adjacent limiting head to facilitate the sliding of the limiting head.

[0010] Furthermore, the outer surfaces of barrel body one, barrel body two and barrel body three are all provided with uniformly distributed reinforcing ribs. The reinforcing ribs and the limiting head are all distributed in a ring and are staggered with each other, which can improve the structural strength of the barrel body.

[0011] Furthermore, it also includes a lid, which is threaded onto the upper part of the outer surface of the barrel body, providing a basis for the barrel body to be quickly closed and opened.

[0012] Furthermore, it also includes handle rings, which are rotatably connected to the front and rear sides of the middle of the three outer surfaces of the barrel, facilitating the movement of the barrel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This variable-capacity packaging plastic bucket has the following advantages:

[0014] Adopting a segmented design, the volume of the packaging plastic bucket can be quickly changed by adding or removing buckets. The insertion effect of the limiting head and limiting post, combined with the limiting head and limiting groove, allows for the quick connection of two adjacent buckets. The connecting holes and internal hex bolts prevent the buckets from loosening or shifting during use. With the sealing component, the volume of the packaging plastic bucket can be flexibly changed, improving the usage effect of the packaging plastic bucket. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a variable volume packaging plastic bucket, including a bucket body 1 and a connecting mechanism 4;

[0022] Barrel body 1: Barrel body 2 is located at its upper end, and barrel body 3 is located at the upper end of barrel body 2. It also includes a lid 6, which is threaded to the upper part of the outer surface of barrel body 3, providing a basis for the barrel to be quickly closed and opened. It also includes a handle 7, which is rotatably connected to the front and rear sides of the middle of the outer surface of barrel body 3, facilitating the movement of the barrel. Barrel body 1, barrel body 2, and barrel body 3 are interconnected and can be combined with lid 6 and handle 7 to form a complete plastic packaging barrel.

[0023] Connecting mechanism 4 includes a limiting groove 41, a limiting head 42, a limiting post 43, and a limiting hole 44. The limiting grooves 41 are all located at the upper ends of barrel body 1 and barrel body 2, with the thickness of the lower part of the limiting groove 41 being greater than the thickness of the lower part of the inner wall. The limiting heads 42 are all located at the lower ends of barrel body 2 and barrel body 3. The outer surfaces of the limiting heads 42 on both the front and rear sides are slidably connected to the inner walls of the laterally adjacent limiting grooves 41. Limiting posts 43 are provided inside the limiting grooves 41 on both the front and rear sides. Limiting holes 44 are opened in the middle of the interior of the limiting heads 42 on both the front and rear sides. The outer surfaces of the limiting posts 43 are slidably connected to the inner walls of the laterally adjacent limiting holes 44. The limiting holes 44 and the limiting posts 43 are all arc-shaped. The lower end of the limiting head 42 on the side furthest from the middle of barrel body 1 protrudes outwards. The limiting head 42 is adapted to the lower part of the limiting groove 41, ensuring that when the limiting head 42 is located on the side of the limiting groove 41 near the limiting post 43, the limiting head 42 can only deflect and cannot move up and down, providing a basis for the quick connection of barrel 1, barrel 2, and barrel 3. The connecting mechanism 4 also includes connecting holes 45 and hexagon socket head cap screws 46. Connecting holes 45 are opened in the middle of the interior of the limiting heads 42 on both the left and right sides. Hexagon socket head cap screws 46 are threaded to the upper left and right sides of the upper middle part of the outer surface of barrel 1 and barrel 2. The hexagon socket head cap screws 46 are threaded to barrel 1 and barrel 2 through bolt holes. The middle part of the outer surface of the hexagon socket head cap screws 46 is threaded to the inner wall of the longitudinally adjacent connecting holes 45. The limiting of the hexagon socket head cap screws 46 can... To prevent loosening or misalignment between the various barrels, the connecting mechanism 4 also includes a sealing assembly 47. The sealing assembly 47 includes a sealing strip 471, slots 472, and insertion rings 473. The slots 472 are all located on the inner edge of the upper end of barrel 1 and barrel 2. The sealing strips 471 are all located in the middle of the bottom wall of the slots 472. The insertion rings 473 are all located on the inner edge of the lower end of barrel 2 and barrel 3. The outer surface of the insertion rings 473 is inserted into the inner wall of the horizontally adjacent slots 472, and the lower end of the insertion rings 473 is abutted against the upper end of the horizontally adjacent sealing strips 471. When the barrels are connected in place, the limiting groove 41, the limiting head 42, and the limiting post 43 limit the movement, and the connecting hole 45 and the internal hex bolt 46 lock in place. The insertion ring 473 fits tightly with the sealing strip 471 to form a seal, providing a basis for sealing between barrels. The connecting mechanism 4 also includes a notch 48, which is located inside the limiting groove 41 on the side away from the limiting post 43. The inner wall of the notch 48 is fitted with the inner wall of the laterally adjacent limiting head 42. The thickness of the notch 48 is greater than the maximum thickness of the limiting head 42, allowing the limiting head 42 to be inserted into the limiting groove 41 from the notch 48, facilitating subsequent deflection and limiting operations. The outer surfaces of barrel 1, barrel 2, and barrel 3 are all provided with evenly distributed reinforcing ribs 5. The reinforcing ribs 5 and the limiting head 42 are arranged in a ring and are staggered, which can improve the structural strength of the barrel.The system includes a connecting mechanism 4, employing a segmented design that allows for quick connection of barrel body 1, barrel body 2, and barrel body 3. In practical applications, the volume of the packaging plastic barrel can be adjusted by increasing or decreasing the number of barrel bodies 2, offering high flexibility.

[0024] The working principle of the variable-capacity packaging plastic bucket provided by this utility model is as follows: When using the packaging plastic bucket, first combine the bucket sections according to the actual situation. If a large volume is needed, use more bucket sections 2; if a small volume is needed, reduce the number of bucket sections 2. For example, if the required volume of the packaging plastic bucket is exactly equal to the volume formed by combining one section of bucket 1, one section of bucket 2, and one section of bucket 3, then take one section of each of bucket 1, bucket 2, and bucket 3. First, place bucket 1 on the ground, pick up bucket 2, and align the limiting head 42 at the lower end of bucket 2 with the notch 48 of the limiting groove 41 at the upper end of bucket 1. Since the thickness of the notch 48 is greater than the diameter of the bucket, the bucket 2 is designed to be more flexible and efficient. The maximum thickness of the limiting head 42 allows the lower end of the second barrel 2 to be inserted into the recess 48 of the upper limiting groove 41 of the first barrel 1. Then, the first barrel 1 is fixed, and the second barrel 2 is rotated clockwise. The lower limiting head 42 of the second barrel 2 moves accordingly until the limiting post 43 inside the first barrel 1 and the limiting hole 44 on the second barrel 2 form an insertion effect. This continues until the side of the limiting head 42 on the front and rear sides of the lower end of the second barrel 2 away from the recess 48 inside the first barrel 1 is in contact with the side of the limiting groove 41 on the front and rear sides of the first barrel 1 near the limiting post 43. At this point, the limiting heads 42 on the left and right sides of the lower end of the second barrel 2 also simultaneously engage with the side of the limiting groove 41 on the left and right sides of the first barrel 1. The inner wall of the limiting groove 41 fits snugly, and the connecting holes 45 on the limiting heads 42 on the left and right sides of the lower end of the barrel 2 are just adjacent to the bolt holes on the barrel 1. Then, the internal hexagonal bolts 46 are screwed into the corresponding bolt holes, so that the middle part of the outer surface of the internal hexagonal bolts 46 is threadedly connected to the inner wall of the corresponding connecting hole 45. At the same time, as the barrel 1 and the barrel 2 are connected, the insertion ring 473 at the bottom of the barrel 2 is also inserted into the slot 472 on the barrel 1. When the limiting post 43 in the barrel 1 and the limiting hole 44 on the barrel 2 form an insertion effect, the middle part of the outer surface of the internal hexagonal bolts 46 is threadedly connected to the inner wall of the corresponding connecting hole 45. After the connection is made, the lower end of the insertion ring 473 also fits against the upper end of the sealing strip 471. The connection between barrel body 1 and barrel body 2 ensures that the insertion ring 473 and the sealing strip 471 are always in close contact, achieving a seal between barrel body 1 and barrel body 2. Then, repeat the above steps to connect barrel body 2 and barrel body 3, completing the connection of the packaging plastic barrel. When it is necessary to change the volume of the packaging plastic barrel again, simply loosen the internal hex bolt 46 on barrel body 2, and then reverse barrel body 3 to quickly separate barrel body 2 and barrel body 3. Then, add or remove barrel body 2 according to the actual situation to change the volume of the packaging plastic barrel.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
