Description

Technical Field

[0001] This utility model relates to the field of packaging barrel technology, and in particular to a pressure-resistant structure for a high-protection packaging barrel. Background Technology

[0002] Packaging drums are containers used in the packaging industry to hold various liquid products. They typically have a certain capacity and structure to meet the needs of transporting, storing, and protecting products. The classification of packaging drums is based not only on their physical characteristics but also on their materials, functions, and uses to meet the needs of different industries and application scenarios.

[0003] A search revealed Chinese patent application number 202122842883.9, which discloses a shock-absorbing and pressure-resistant plastic packaging barrel, including a packaging barrel body, a shock-absorbing component, and a heat-insulating component. The shock-absorbing component is disposed within the packaging barrel body and includes a protective top cover and a shock-absorbing structure. The protective top cover is disposed on the top of the packaging barrel body, and the shock-absorbing structure is disposed within the packaging barrel body. An outer pressure-resistant plate is compressed by a pressure-resistant spring to press an inner pressure-resistant plate, which in turn compresses the outer wall of the material cavity. Under the action of the pressure-resistant spring, the outer wall returns to its initial state, protecting the raw material in the material cavity and preventing leakage due to compression. The protective top cover is compressed by a protective spring to press a protective bottom cover, which in turn compresses the outer wall of the top of the packaging barrel body. Under the action of the protective spring, the top of the packaging barrel body is protected, preventing damage to the packaging barrel body from the impact of falling objects and causing raw material leakage.

[0004] Although the aforementioned patent can prevent damage to the packaging barrel body due to the impact of falling objects by squeezing the protective bottom cover with a protective spring, and the protective bottom cover squeezing the outer wall of the top of the packaging barrel body, the packaging barrel is generally a single-layer structure, which is prone to breakage after damage, resulting in leakage of the internal materials.

[0005] Therefore, there is an urgent need for a high-protection, pressure-resistant packaging barrel structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing packaging barrels are generally single-layered structures, which are prone to breakage and leakage of internal materials after damage. Therefore, this invention proposes a high-protection, pressure-resistant packaging barrel structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-protection, pressure-resistant packaging barrel structure includes an inner cylinder, an outer shell mounted on the outside of the inner cylinder, a mesh layer fixedly installed on the outside of the inner cylinder between the outer shell and the inner cylinder, a top plate mounted on the top of the outer shell, a barrel lid detachably mounted on the top of the outer shell, a base mounted on the bottom of the outer shell, multiple caster wheels mounted on the base, a bottom plate fixedly mounted on the bottom of the mesh layer, multiple fastening bolts mounted on the bottom of the base, and multiple threaded holes that mate with the fastening bolts on the mesh layer. The outer shell is fixedly connected to the bottom plate by the fastening bolts.

[0009] As a preferred technical solution of this application, a second annular hoop is installed on the top and bottom of the outer side of the outer shell, and two first annular hoops are installed in the middle of the outer side of the outer shell, and the two first annular hoops in the middle are connected by multiple connecting rods.

[0010] As a preferred technical solution of this application, a plurality of reinforcing strips are installed between the first annular hoop and the second annular hoop, and the connection between two adjacent reinforcing strips forms a triangle.

[0011] As a preferred technical solution of this application, the movable wheel assembly includes a screw threadedly connected to the base, and a universal wheel is fixedly installed at the bottom end of the screw.

[0012] As a preferred technical solution of this application, a handle is rotatably mounted on the top of the outer casing, located below the top plate.

[0013] As a preferred technical solution of this application, a sliding groove is provided on the inner side of the top plate, the bottom end of the sliding groove is connected to a slot, the bottom of the slot is connected to a movable plate by a spring, and multiple locking blocks are fixedly installed on the outer bottom of the bucket lid.

[0014] As a preferred technical solution of this application, both the top plate and the bucket lid are equipped with indicator strips.

[0015] As a preferred technical solution of this application, a sealing post is installed at the bottom of the bucket lid, a vertical plate is installed at the top of the inner cylinder, and a slot is provided on the outside of the sealing post on the bucket lid, the slot cooperating with the vertical plate.

[0016] Compared with the prior art, this utility model provides a high-protection, pressure-resistant packaging barrel structure, which has the following beneficial effects:

[0017] 1. The high-protection packaging barrel has a pressure-resistant structure. Through the inner cylinder and the outer shell installed on the outside of the inner cylinder, the outer shell can effectively protect the inner cylinder. The mesh layer installed on the outside of the inner cylinder can improve the pressure resistance, improve the pressure resistance and stability during use, and solve the problem that the packaging barrels in the existing technology are generally single-layer structures, which are prone to breakage after damage, resulting in leakage of the internal materials.

[0018] 2. The high-protection packaging barrel has a pressure-resistant structure. Through multiple movable wheel assemblies set on the base, the position of the casters can be adjusted by rotating the screw. On the one hand, the casters can be moved easily, and on the other hand, the casters can be stored away. The operation is simple and convenient, which solves the problem that the packaging barrel itself is heavy and inconvenient to move and transport in the existing technology.
