Description

Technical Field

[0001] This utility model relates to the field of closed-top bucket technology, and in particular to a plastic closed-top bucket that is easy to stack. Background Technology

[0002] A closed-top plastic container is a plastic container with a sealed opening, typically used for storing and transporting various liquids and solids. They are mostly made of plastic materials such as polyethylene, polypropylene, and polyester through blow molding, injection molding, vacuum forming, or rotational molding processes. Closed-top plastic containers are widely used in industries such as chemical, pesticide, pharmaceutical, food, hardware, electronics, and electromechanical. A closed-top container refers to a container with an inlet or vent with a diameter no larger than a certain size. The design feature of this type of container is its airtightness, and it is typically used to store chemicals, solvents, lubricants, adhesives, and other substances.

[0003] To address this, Chinese patent application CN206367697U discloses a novel closed-top plastic bucket with a breathable design. Its structure includes a plastic bucket body, a bucket mouth, a top cover, a vent, a groove, and a lid. The plastic bucket body is fixedly connected to the bucket mouth, and the top cover is also fixedly connected to the bucket mouth. The top cover has a vent, the groove is fixedly connected to the top cover, and the lid is threaded to the vent. The lid consists of a lid body, an ear seat, a cross-shaped through hole, a sealing ring, and a filter hole. This novel closed-top plastic bucket with a breathable design utilizes a recessed area on the lid of a 200L closed-top plastic bucket to install a breathable membrane. A cross-shaped hole is designed in the center of the lid. Gas passes through the breathable membrane and is discharged through the hole in the outer lid, allowing air and gas molecules to pass through the breathable membrane. This continuously balances the pressure, preventing the container from expanding or collapsing. Even when in contact with high-viscosity or low-surface-tension liquids, it maintains breathability and prevents leakage of hazardous liquids.

[0004] The aforementioned novel closed-top plastic bucket with a breathable design incorporates a recessed area on the lid of a 200L closed-top plastic bucket to install a breathable membrane. A cross-shaped hole is designed in the center of the lid, allowing gas to escape through the breathable membrane and the hole in the outer lid. This allows air and gas molecules to pass through the breathable membrane, thereby continuously balancing the pressure and preventing the container from expanding or collapsing. Even when in contact with high-viscosity or low-surface-tension liquids, it can maintain breathability and prevent leakage of hazardous liquids. However, when storing the closed-top buckets, they need to be stacked together, but during stacking, the closed-top buckets may shift or tip over. Utility Model Content

[0005] The purpose of this invention is to provide a plastic closed-top bucket that is easy to stack, in order to solve the problem that existing plastic closed-top buckets are difficult to stack.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic closed-top bucket that is easy to stack, including a base;

[0007] The bottom end of the base is provided with a groove, the top end of the base is provided with a barrel, and the top end of the barrel is provided with a top plate.

[0008] A cover is installed at the top of the top plate, and a positioning structure is installed at the top of the top plate. The positioning structure includes an installation block installed at the top of the top plate.

[0009] The mounting block has a movable groove inside, and a spring is installed inside the movable groove. A buckle is installed on one side of the spring, and a baffle is installed on the top of the buckle.

[0010] In use, one bucket is first stacked on top of another. The base can then be inserted into the mounting block. Once the base is fully inserted, the spring's elasticity causes the buckle to pop out automatically and engage with the groove on the base. The buckle secures the base, allowing the two buckets to be stacked together. The handle and the connecting buckle at the bottom of the buckets form a locking mechanism. The handle can be inserted into the connecting buckle, and the combination of the handle and the connecting buckle connects the two buckets together, preventing them from tipping over.

[0011] Furthermore, an anti-slip structure is installed on the outer side of the bucket body. The anti-slip structure includes a first clamp installed on the top of the bucket body, a second clamp installed on one side of the first clamp, fixing screws installed at both ends of the first clamp, and a nut installed on one side of the fixing screw. An anti-slip pad is installed at the bottom of the first clamp. The anti-slip structure can enhance the friction of the bucket body surface.

[0012] Furthermore, the outer side of the anti-slip mat is provided with anti-slip patterns, which are arranged at equal intervals on the outer side of the anti-slip mat. The anti-slip patterns can enhance the friction of the anti-slip mat.

[0013] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the nut are threadedly connected, and the fixing screw and the nut cooperate to fix the first clamp and the second clamp.

[0014] Furthermore, the spring is helical in shape, and the spring and the buckle form an elastic connection, giving the spring elasticity.

[0015] Furthermore, the outer diameter of the buckle is smaller than the inner diameter of the moving groove, and the buckle and the moving groove form a sliding structure, allowing the buckle to slide inside the moving groove.

[0016] Furthermore, a connecting structure is installed on the outer side of the top plate. The connecting structure includes a fixing plate installed on the outer side of the top plate, and a rotating shaft installed on the inner side of the fixing plate. A handle is installed at the top of the rotating shaft. The connecting structure includes a connecting buckle installed at the bottom of the barrel. The connecting structure can connect multiple barrels.

[0017] Furthermore, the top of the connecting buckle is provided with a slot, and the handle and the connecting buckle form a locking structure, which facilitates disassembly.

[0018] Furthermore, the connecting buckles are arranged at equal intervals and in a ring shape, and the connecting buckles can lock the handle in place.

[0019] Furthermore, the pivot is rotatable and is symmetrically distributed about the central axis of the handle, allowing the handle to rotate.

[0020] The advantages of the easily stackable plastic closed bucket provided by this utility model are: when in use, the buckets can be stacked together, the positioning structure can stably fix the stacked buckets, the connecting structure can prevent the buckets from tipping over when stacked, and the anti-slip structure makes the buckets easier to pick up.

[0021] By installing an installation block at the top of the top plate, the installation block and the base at the bottom of the bucket form an interlocking structure. When stacking, after one bucket is placed on top of another, the base can be inserted into the installation block. The buckle on the inside of the installation block can move inside the moving groove. Due to the inclined surface at the top of the buckle, when the base is inserted into the installation block, the buckle is pushed into the moving groove, allowing the base to be inserted into the installation block. After the base is fully inserted into the installation block, due to the elasticity of the spring, the spring will drive the buckle to automatically pop out and insert into the groove on the base. The buckle can fix the base, so the two buckets can be stacked together. When it is necessary to disassemble the bucket, the buckle can be moved by the baffle to release the buckle from the base, and the bucket can be disassembled. This achieves the purpose of making it easy to stack plastic closed buckets.

[0022] By installing a fixing plate on the outside of the top plate, the handle on the inside of the fixing plate can rotate along the pivot. When carrying, the bucket can be lifted by the handle to make it easy to carry. At the same time, when stacking, the handle and the connecting buckle at the bottom of the bucket form an interlocking structure. The handle can be inserted into the connecting buckle. The handle and the connecting buckle can connect the two buckets together to prevent the bucket from tipping over. This achieves the purpose of preventing the plastic closed bucket from tipping over.

[0029] 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.

[0030] Please see Figures 1-5 One embodiment of this utility model is a plastic closed-top bucket that is easy to stack, including a base 3.

[0031] The bottom of the base 3 is provided with a groove 6, and the top of the base 3 is provided with a barrel 1. The outer side of the barrel 1 is provided with an anti-slip structure 2. The anti-slip structure 2 includes a first clamp 201 installed on the top of the barrel 1, a second clamp 202 installed on one side of the first clamp 201, and fixing screws 206 installed at both ends of the first clamp 201. The outer side wall of the fixing screw 206 is uniformly provided with external threads, and the inner side wall of the nut 205 is uniformly provided with internal threads that cooperate with the external threads. The fixing screw 206 and the nut 205 are threadedly connected.

[0032] A nut 205 is installed on one side of the fixing screw 206, and an anti-slip pad 203 is installed at the bottom of the first clamp 201. Anti-slip patterns 204 are provided on the outer side of the anti-slip pad 203, and the anti-slip patterns 204 are arranged at equal intervals on the outer side of the anti-slip pad 203.

[0033] See attached document Figure 1-2 and attached Figure 5 As shown, the first clamp 201 and the second clamp 202 cooperate with each other. After the first clamp 201 and the second clamp 202 are connected together, they can be wrapped around the barrel 1. The fixing screw 206 and the nut 205 form a threaded connection. Tightening the fixing screw 206 and the nut 205 can fix the first clamp 201 and the second clamp 202 together. This can also fix the anti-slip mat 203 to the surface of the barrel 1. The anti-slip mat 203 can be made of rubber material. The anti-slip texture 204 can enhance the friction of the surface of the anti-slip mat 203, which makes it easier for the user to lift the barrel 1.

[0034] A top plate 7 is installed at the top of the barrel 1. A connecting structure 5 is installed on the outside of the top plate 7. The connecting structure 5 includes a fixing plate 501 installed on the outside of the top plate 7, and a rotating shaft 502 installed on the inside of the fixing plate 501. The rotating shaft 502 can rotate and is symmetrically distributed about the central axis of the handle 503.

[0035] A handle 503 is installed at the top of the rotating shaft 502. The connecting structure 5 includes a connecting buckle 504 installed at the bottom of the barrel 1. The connecting buckles 504 are arranged at equal intervals and distributed in a ring.

[0036] The top of the connecting buckle 504 is provided with a slot, and the handle 503 and the connecting buckle 504 form a locking structure.

[0037] See attached document Figure 1-2 and attached Figure 4 As shown, the handle 503 on the inner side of the fixing plate 501 can rotate along the pivot 502. When carrying, the bucket 1 can be lifted by the handle 503 to make it easy to carry. At the same time, when stacking, the handle 503 and the connecting buckle 504 at the bottom of the bucket 1 form a locking structure. The handle 503 can be inserted into the connecting buckle 504. The handle 503 and the connecting buckle 504 can connect the two buckets 1 together to prevent the buckets 1 from tipping over.

[0038] A cover 8 is installed at the top of the top plate 7, and a positioning structure 4 is installed at the top of the top plate 7. The positioning structure 4 includes an installation block 401 installed at the top of the top plate 7.

[0039] The mounting block 401 has a movable groove 403 inside, and a spring 404 is installed inside the movable groove 403. The spring 404 is spiral in shape, and the spring 404 and the buckle 402 form an elastic connection.

[0040] A buckle 402 is installed on one side of the spring 404. The outer diameter of the buckle 402 is smaller than the inner diameter of the moving groove 403. The buckle 402 and the moving groove 403 form a sliding structure. A baffle 405 is installed on the top of the buckle 402.

[0041] See attached document Figure 1-3 As shown, the mounting block 401 and the base 3 at the bottom of the barrel 1 form a locking structure. When stacking, after one barrel 1 is stacked on top of another barrel 1, the base 3 can be locked into the mounting block 401. The buckle 402 on the inner side of the mounting block 401 can move inside the moving groove 403. Due to the inclined surface at the top of the buckle 402, when the base 3 is locked into the mounting block 401, the buckle 402 will be pushed into the moving groove 403, allowing the base 3 to be locked into the mounting block 401. After the base 3 is fully locked into the mounting block 401, due to the elasticity of the spring 404, the spring 404 will drive the buckle 402 to automatically pop out and lock into the groove on the base 3. The buckle 402 can fix the base 3. In this way, the two barrels 1 can be stacked together. When it is necessary to disassemble the barrel 1, the buckle 402 can be moved by the baffle 405 so that the buckle 402 is no longer locked into the base 3, and the barrel 1 can be disassembled.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
