Description

Technical Field

[0001] The utility model belongs to the technical field of plastic barrels, and particularly relates to a plastic barrel with an exhaust structure. Background Art

[0002] Plastic barrels are mostly used for the storage and transportation of various liquids. They have good properties for special dangerous goods packaging. They are not easy to break, rust-proof, lightweight, and have excellent oil and strong corrosion resistance. They are mostly used for dangerous goods packaging that requires heat preservation, moisture resistance, pressure resistance, and corrosion resistance.

[0003] At present, the Chinese utility model with publication number: CN217228576U discloses a vented plastic barrel, which relates to the field of plastic products, and includes a barrel body and a bottle cap, wherein the barrel body is provided with a liquid inlet, the bottle cap is threadedly connected to the liquid inlet, a vent hole is formed through the bottle cap, and a waterproof and breathable membrane is detachably provided on the inner side of the bottle cap at the vent hole. This application helps prevent the gas from being unable to be discharged for a long time, resulting in the explosion of the plastic barrel, that is, it helps to improve the safety of the plastic barrel.

[0004] The above patent mainly uses a waterproof and breathable membrane to prevent moisture from entering the exhaust holes. Although moisture cannot enter, it will accumulate on the membrane and block the membrane holes, causing gas to be unable to discharge, so its practicality is poor; at the same time, existing plastic barrels are easily deformed by objects, the overall pressure resistance of plastic barrels is poor, and they are easily punctured by sharp objects, causing the internal liquid to flow out, posing certain safety hazards. Utility Model Content

[0005] The utility model aims to provide a plastic barrel with an exhaust structure, which has the advantages of being able to exhaust the inside of the plastic barrel, while preventing moisture from entering and improving the pressure resistance of the plastic barrel.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a plastic barrel with an exhaust structure, comprising a plastic barrel, a barrel cover threadedly connected to the top of the plastic barrel, an exhaust hole opened inside the barrel cover, a threaded barrel threadedly connected to the side of the top of the barrel cover close to the exhaust hole, a sealing cover 1 slidably connected to the top of the threaded barrel, a piston slidably connected to the threaded barrel and the exhaust hole respectively fixedly connected to the bottom of the sealing cover 1, a spring fixedly connected to the threaded barrel on the surface of the top of the piston, a convex ring slidably connected to the sealing cover 1 on the top of the threaded barrel, and a drainage hole opened on the surface of the threaded barrel.

[0007] By adopting the above technical scheme, the gas pressure inside the plastic barrel pushes the spring to contract, thereby opening the piston to exhaust air, and at the same time, the exhaust hole is sealed by a sealing cover, so that when external moisture enters the interior, it is blocked by the convex ring and flows out of the threaded barrel through the drainage hole. The setting inside the threaded barrel makes it possible to exhaust the inside of the plastic barrel while preventing moisture from entering, and moisture will not block the exhaust hole, thereby improving practicality; when the plastic barrel is squeezed, the plastic barrel is supported by reinforcement strips and support grids, and at the same time, the support grid separates the plastic barrel and the inner interlayer into multiple independent spaces. When the plastic barrel is pierced by an object, the internal interlayer can ensure that the liquid will not leak, which not only improves the pressure resistance of the plastic barrel, but also reduces the risk of the plastic barrel being pierced, thereby improving safety.

[0008] The utility model is further configured as follows: an inner interlayer is arranged inside the plastic barrel, a support grid is fixedly connected between the surface of the inner interlayer and the plastic barrel, and a reinforcement strip is fixedly connected to the surface of the plastic barrel.

[0009] The adoption of the above technical solution not only improves the compression resistance of the plastic barrel, but also reduces the risk of the plastic barrel being punctured, thereby improving safety.

[0010] The utility model is further configured as follows: a handle is rotatably connected to the top of the surface of the plastic bucket.

[0011] By adopting the technical solution, the plastic bucket can be easily picked up and carried.

[0012] The utility model is further configured as follows: one side of the top of the barrel cover is opened and slidably connected with a sealing cover 2.

[0013] By adopting the above technical solution, the barrel cover can be opened to quickly pour out the liquid inside the plastic barrel.

[0014] The utility model is further configured as follows: a support bar is fixedly connected to the bottom of the plastic barrel.

[0015] By adopting the technical solution, the stability of the bottom of the plastic barrel is improved to prevent direct contact with the ground.

[0016] The utility model is further configured as follows: sealing rings that cooperate with each other are bonded between the threaded barrel and the barrel cover.

[0017] The above technical solution is adopted to improve the sealing performance and prevent moisture from penetrating into the interior.

[0018] The utility model is further configured as follows: an arc-shaped groove structure is provided on the top of the sealing cover 1.

[0019] The above technical solution is adopted to facilitate the water on the top to be led to both sides, thereby reducing the water entering into the threaded tube.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The gas pressure inside the plastic barrel pushes the spring to contract, thereby opening the piston to exhaust air. At the same time, the exhaust hole is sealed by the sealing cover, so that when external moisture enters the interior, it is blocked by the convex ring and flows out of the threaded barrel through the drainage hole. This makes it possible to exhaust the inside of the plastic barrel and prevent moisture from entering. The moisture will not block the exhaust hole, thereby improving practicality.

[0022] 2. When the plastic barrel is squeezed, the reinforcement strips and support grids are used to support the plastic barrel. At the same time, the support grids separate the plastic barrel and the inner interlayer into multiple independent spaces. When the plastic barrel is punctured by an object, the inner interlayer can ensure that the liquid will not leak, which not only improves the pressure resistance of the plastic barrel, but also reduces the risk of the plastic barrel being punctured, thereby improving safety.
