Description

Technical Field

[0001] This utility model relates to the field of modular plastic bucket technology, and in particular to a modular plastic bucket with variable volume. Background Technology

[0002] Modular plastic buckets are plastic containers composed of multiple parts that are typically joined together using specific connection methods, such as snaps, threads, and slots, to form a complete container that can be used to store or transport various liquids and solids. Compared with traditional one-piece molded plastic buckets, modular plastic buckets have advantages such as being easier to clean, maintain, and transport, and are widely used in the food, chemical, and medical industries.

[0003] Existing modular plastic buckets are typically composed of multiple bucket bodies. This means that when the volume of the plastic bucket needs to be changed, the bucket bodies must first be disassembled, and then the number of bucket bodies added or removed to adjust the volume. This is not only cumbersome but also reduces work efficiency. Furthermore, repeated installation and disassembly can cause wear and tear on the connecting structure, easily leading to loosening of the connectors and affecting the sealing of the bucket body, thus affecting the use of the plastic bucket. After searching, it was found that the technical solution provided by the utility model application with application number CN202223610481.7 also has the above-mentioned problems. Utility Model Content

[0008] According to the aforementioned variable-volume modular plastic bucket, a drain outlet is fixedly connected to the outer surface of the bucket bottom, and a drain valve is fixedly connected to the outer surface of the drain outlet to facilitate the discharge of liquid from the plastic bucket.

[0009] According to the aforementioned variable-volume modular plastic bucket, the outer surface of the bidirectional screw is rotatably connected to the bucket body, and the outer surface of the gear is slidably connected to the bucket body, which facilitates the rotation of the gear ring to drive the gear to rotate, thereby driving the bidirectional screw to rotate.

The fixing and releasing of the fixing rod are achieved through the connection relationship between the locking block and the connecting seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The design incorporates a gear ring, gears, a double-acting screw, and an extension cylinder, facilitating volume adjustment of the plastic bucket without disassembling the bucket body.

[0027] Reference Figure 1-6This utility model discloses a variable-volume modular plastic bucket, comprising: a bucket body 1, a bucket lid 2, and a bucket bottom 3. A water inlet 20 is fixedly connected to the upper surface of the bucket lid 2, and a sealing cap 21 is threadedly connected to the outer surface of the water inlet 20. A drain outlet 22 is fixedly connected to the outer surface of the bucket bottom 3, and a drain valve 23 is fixedly connected to the outer surface of the drain outlet 22. A gear ring 4 is slidably connected to the inner surface of the bucket body 1, and a gear 5 is meshed with the inner surface of the gear ring 4. The outer surface of the gear 5 is slidably connected to the bucket body 1. A bidirectional screw 6 is fixedly connected to the inner surface of the gear 5, and the outer surface of the bidirectional screw 6 is rotatably connected to the bucket body 1. An extension tube 7 is threadedly connected to the outer surface of the bidirectional screw 6. The length of the bucket body 1 can be adjusted by adjusting the length of the extension tube 7 extending from the inside of the bucket body 1, thereby adjusting the volume of the plastic bucket. The outer surface of the extension tube 7 is slidably connected to the bucket body 1. A fixing ring 8 is fixedly connected to the upper surface of the extension tube 7, and a sealing gasket 9 is fixedly connected to the upper surface of the fixing ring 8. This facilitates sealing the gap between the fixing ring 8 and the bucket lid 2 and the bucket bottom 3 after the plastic bucket is assembled. A sealing ring 10 is fixedly connected to the inner surface of the bucket body 1, which ensures that the extension tube 7 is always in close contact with the extension tube 7 when it moves, ensuring the sealing between the bucket body 1 and the extension tube 7 and preventing liquid leakage. The inner surface of the extension tube 7 slides with the sealing ring 10.

[0028] Connecting seats 11 are fixedly connected to the outer surfaces of both the barrel body 1 and the barrel bottom 3. First springs 12 are fixedly connected to both sides of the connecting seats 11. Pressing blocks 13 are fixedly connected to the end of the first springs 12 away from the connecting seats 11. A connecting rod 14 is fixedly connected to the side of the pressing block 13 connected to the first springs 12. The outer surface of the connecting rod 14 is slidably connected to the connecting seats 11. A push plate 15 is fixedly connected to the end of the connecting rod 14 away from the pressing block 13, which facilitates pushing the locking block 19 out of the connecting seats 11, thereby removing the fixing rod 17 from the connecting seats 11. The outer surface of the push plate 15 is slidably connected to the connecting seats 11. A fixing seat 16 is fixedly connected to the outer surface of the fixing ring 8. A fixing rod 17 is fixedly connected to the upper surface of the fixing seat 16. The outer surface of the fixing rod 17 is slidably connected to the connecting seats 11. A second spring 18 is fixedly connected to the inner surface of the fixing rod 17. A locking block 19 is fixedly connected to the end of the second spring 18 away from the fixing rod 17. The outer surface of the locking block 19 is slidably connected to the fixing rod 17.

[0029] Working principle: The fixing rod 17 is inserted into the connecting seat 11 on the outside of the bucket lid 2 and the bucket bottom 3. During insertion, the locking block 19 is squeezed into the fixing rod 17 by the connecting seat 11 and compresses the second spring 18. When the fixing rod 17 is inserted to the top of the connecting seat 11, the locking block 19 pops out under the action of the second spring 18 and locks into the connecting seat 11 to fix the fixing rod 17. Thus, the fixing ring 8 is connected and fixed together with the bucket lid 2 and the bucket bottom 3 through the fixing seat 16, and the sealing gasket 9 is compressed. The sealing gasket 9 seals the gaps in the connection. When the volume of the plastic bucket needs to be adjusted, rotate... The gear ring 4 drives the bidirectional screw 6 to rotate through the meshing action of the gear ring 4 and the gear 5. The rotation of the bidirectional screw 6 drives the extension cylinder 7 to move, thereby adjusting the height of the lid 2 and thus the volume of the plastic bucket. During the movement of the extension cylinder 7, the sealing ring 10 and the extension cylinder 7 always remain tightly fitted to achieve a sealing effect and prevent liquid leakage. When it is necessary to remove the plastic bucket, press the pressing blocks 13 on both sides of the connecting seat 11. The connecting rod 14 drives the push plate 15 to move and push the locking block 19 out of the connecting seat 11, thereby removing the fixation of the fixing rod 17 and thus separating the plastic bucket.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
