Description

Technical Field

[0001] The utility model relates to the technical field of packaging barrels, in particular to an integrated film-molded anti-corrosion packaging barrel. Background Art

[0002] With the development of society, people have placed higher demands on the performance of packaging barrels. The corrosion resistance of existing packaging barrels no longer meets this requirement. After a period of use, they will corrode and break, resulting in a short service life and limiting their application. Industrial production requires the prevention of leakage of corrosive substances such as chemicals, acids and alkalis. These substances are often highly corrosive and can cause serious harm to the environment and human health. Therefore, the development of packaging barrels that can effectively protect these substances and prevent them from leaking is particularly important.

[0003] However, the existing research on packaging barrels is limited and cannot meet the needs of various working conditions. When protecting the raw materials in the barrel, ordinary lids are used for sealing protection, but the sealing effect is poor. The outside air can easily enter the barrel and cause corrosion and pollution to the raw materials, making it impossible to provide effective protection. Therefore, it is necessary to develop more suitable one-piece anti-corrosion packaging barrels.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an integrated film-molded anti-corrosion packaging barrel is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated film-molded anti-corrosion packaging barrel to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated film-molded anti-corrosion packaging barrel, comprising an anti-corrosion plastic barrel, a threaded opening fixedly installed in the middle of the surface of the anti-corrosion plastic barrel, a limiting plate fixedly provided on the lower side of the outer surface of the threaded opening, an anti-corrosion rubber ring fixedly provided on the upper end of the threaded opening, a sealing cover threadedly connected to the outer surface of the threaded opening, a sealing ring fixedly provided on the bottom end of the sealing cover, and an exhaust mechanism provided in the middle of the upper surface of the sealing cover.

[0007] Preferably, the exhaust mechanism includes a fixed cylinder fixedly installed in the middle of the upper surface of the sealing cover, and the interior of the fixed cylinder is communicated with the inner side of the lower side of the sealing cover.

[0008] Preferably, the exhaust mechanism further comprises air holes evenly distributed on the outer surface of the fixing cylinder, and the air holes are located on the upper side of the sealing cover.

[0009] Preferably, the exhaust mechanism further comprises a spring fixedly mounted on the inner surface of the fixed cylinder, a piston is fixedly mounted on the lower end of the spring, and the piston is located below the air hole.

[0010] Preferably, grooves are provided on both left and right sides of the lower end of the outer surface of the anti-corrosion plastic barrel, and handles are fixedly provided on both left and right sides of the upper end of the anti-corrosion plastic barrel.

[0011] Preferably, the position of the handle corresponds to the position of the groove in vertical direction, and the shapes of the handle and the groove match.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a limiting plate, an anti-corrosion rubber ring, a sealing cover and a sealing ring. After the sealing cover is screwed onto the threaded opening to seal the anti-corrosion plastic barrel, the anti-corrosion rubber ring will cling to the upper inner side of the sealing cover to seal the inner seam between the sealing cover and the threaded opening. At the same time, the sealing ring will fit tightly with the upper surface of the limiting plate to seal the outer seam between the sealing cover and the threaded opening. The use of an inner and outer double-layer sealing method can greatly improve the sealing performance of the entire packaging barrel, effectively preventing outside air from easily entering the barrel to corrode and contaminate the raw materials, and greatly improving the sealing protection capability of the raw materials.

[0014] 2. This utility model utilizes an exhaust mechanism, a fixed cylinder, an air hole, a spring, and a piston. The raw materials stored inside the anti-corrosion plastic barrel generate gas. Excess gas pushes the piston to compress the spring upward, thereby connecting the air hole with the interior of the barrel and discharging the excess gas. This prevents the excessive gas released by the raw materials inside from causing the anti-corrosion plastic barrel to expand, deform, or even explode, greatly improving the safety of the anti-corrosion plastic barrel.

[0015] 3. The utility model provides grooves and handles, and the handles are used to facilitate the transportation of the entire anti-corrosion plastic barrel. At the same time, when the anti-corrosion plastic barrels are stacked, the handles of the lower anti-corrosion plastic barrels are inserted into the grooves of the upper anti-corrosion plastic barrels, so that stable stacking can be achieved.
