Description

Technical Field

[0001] This utility model relates to the technical field of double-layer plastic buckets, specifically a double-layer plastic bucket with an anti-corrosion structure. Background Technology

[0002] Double-walled plastic drums, with their structural advantages and excellent corrosion resistance, are widely used in many fields such as chemical, food, and pharmaceutical industries. They effectively protect stored substances from corrosive external environments and prevent leakage that could contaminate the environment. Double-walled plastic drums are used to store and transport various chemical raw materials, intermediates, and finished products, such as paints, dyes, pesticides, and fertilizers. Since most of these substances are corrosive, double-walled plastic drums provide a reliable storage solution, ensuring the safety and stability of chemical production. In food processing and storage, double-walled plastic drums can be used to store edible oils, juices, and condiments. Their non-toxic, odorless, and corrosion-resistant properties ensure food hygiene and safety, preventing food from being contaminated by external pollutants and chemical substances. Double-walled plastic drums should be placed in dry, ventilated, and cool places, avoiding direct sunlight and high temperatures, as high temperatures may accelerate the aging and deformation of the plastic material, affecting its corrosion resistance. They should also be kept away from fire sources and flammable materials to prevent fire accidents. Regular inspections of double-walled plastic drums should be conducted, including visual inspection and leak detection, checking for damage, deformation, aging, etc.

[0003] According to Chinese Patent Publication No. CN210391902U, a low-temperature resistant double-layer plastic bucket includes an outer bucket, an inner bucket, and a cover plate. The outer bucket, inner bucket, and cover plate form a double-layer plastic bucket, with the inner bucket located inside the outer bucket. The cover plate is equipped with a connecting mechanism, which includes a rotating shaft and a threaded rod. The threaded rod is rotatably connected to the left and right ends of the bottom of the cover plate via bearings. The top of the threaded rod penetrates the cover plate and extends to the upper part of the top of the cover plate. A second pulley is fitted onto the upper part of the outer surface of the threaded rod. The rotating shaft is rotatably connected to the middle end of the top of the cover plate via bearings. A first pulley is fitted onto the outer surface of the rotating shaft, and a belt is fitted onto the outer surface of the first pulley. This invention solves the problems of poor sealing performance leading to poor heat preservation in current low-temperature resistant double-layer plastic buckets, and their short service life due to susceptibility to impact and wear, by using a fixing block, a connecting mechanism, and a protective pad in cooperation.

[0004] In the above solution, a threaded rod is rotatably connected to the left and right ends of the bottom of the cover plate via bearings. The top of the threaded rod penetrates the cover plate and extends to the upper part of the top of the cover plate. A second pulley is fitted on the upper part of the outer surface of the threaded rod. This results in the following disadvantages: the outer surface of the existing double-layer plastic bucket is easily dented and twisted by compression and impact. Workers need to spend a lot of time to repair it, which is time-consuming, labor-intensive, and cumbersome. This reduces the overall strength of the bucket and its practicality. Moreover, the liquid inside the plastic bucket will shake during transportation. Continuous shaking may cause the liquid to leak out, reducing flexibility and making it unsuitable for long-term use. Therefore, there is an urgent need for a double-layer plastic bucket with an anti-corrosion structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layered plastic bucket with a corrosion-resistant structure to solve the problem mentioned in the background art that the outer surface of the double-layered plastic bucket is easily dented and twisted when squeezed and impacted, and workers have to spend a lot of time to repair it, which is time-consuming and laborious.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer plastic bucket with an anti-corrosion structure, comprising an outer bucket body, a bucket bottom fixedly connected to the bottom surface of the outer bucket body, an inner bucket body fixedly connected to the inside of the outer bucket body, a plurality of elastic columns arranged in a ring on the outer wall of the inner bucket body, a protective cylinder provided inside the outer bucket body, the protective cylinder being sleeved on the outside of the inner bucket body, a restoring inner core installed on the outer wall of the protective cylinder, the elastic columns being disposed between the protective cylinder and the inner bucket body, the restoring inner core being disposed between the outer bucket body and the outer protective cylinder, and an extension cylinder fixedly connected to the top surface of the inner bucket body.

[0007] Preferably, a turntable is fixedly connected to the bottom surface of the inner barrel, a rotating rod is rotatably connected to one end of the turntable, and two anti-wave plates are fixedly connected to the outer wall of the rotating rod, with multiple round head grooves opened on the anti-wave plates.

[0008] Preferably, the outer barrel is provided with multiple fixing grooves and threaded grooves.

[0009] Preferably, the top surface of the outer barrel is provided with a lid, and the lid has an anti-slip groove.

[0010] Preferably, a reinforcing ring is fixedly connected to the outer wall of the outer barrel, and two handles are installed on the reinforcing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model discloses a double-layer plastic bucket with an anti-corrosion structure. During use, when the outer wall of the outer bucket is squeezed and impacted, the elastic column is squeezed inward by the force. When the external pressure is gone, the elastic column recovers and resists pressure outward. The elastic column has a high-strength buffering and rebound effect, which enhances the impact resistance and deformation resistance. The elastic column absorbs the impact energy through compression deformation, transforming local concentrated stress into dispersed elasticity, thus achieving the anti-compression effect. Then, under the action of the restoring inner core, the anti-compression effect of the outer wall of the outer bucket is increased. When the double-layer plastic bucket is impacted and squeezed, the restoring inner core can absorb most of the impact energy through elastic deformation, reducing damage to the bucket structure, avoiding bucket wall dents or cracks, extending its service life, and improving structural stability and durability.

[0013] 2. This utility model provides a double-layered plastic bucket with an anti-corrosion structure. During use, the anti-sloshing plate can block the sloshing of liquid during the transportation of the plastic bucket, reduce the kinetic energy generated by the sloshing of liquid, divide the liquid into different areas to restrict the flow of liquid, effectively reduce the amplitude of liquid sloshing in the bucket, improve the stability of transportation, enhance flexibility, and improve safety.

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.

[0020] Please see Figure 1-4 This utility model provides a double-layered plastic bucket with an anti-corrosion structure, including an outer bucket body 1, a bucket bottom 2 fixedly connected to the bottom surface of the outer bucket body 1, an inner bucket body 3 fixedly connected to the inside of the outer bucket body 1, a plurality of elastic columns 7 arranged in a ring on the outer wall of the inner bucket body 3, a protective cylinder 6 provided inside the outer bucket body 1, the protective cylinder 6 being sleeved on the outside of the inner bucket body 3, a restorative inner core 5 installed on the outer wall of the protective cylinder 6, the elastic columns 7 being all located between the protective cylinder 6 and the inner bucket body 3, the restorative inner core 5 being located between the outer bucket body 1 and the outer protective cylinder 6, and an extension tube fixedly connected to the top surface of the inner bucket body 3. 4. A turntable 8 is fixedly connected to the bottom surface of the inner barrel 3. A rotating rod 9 is rotatably connected to one end of the turntable 8. Two baffle plates 10 are fixedly connected to the outer wall of the rotating rod 9. Multiple round head grooves 11 are opened on the baffle plates 10. Multiple fixing grooves 12 are installed on the outer barrel 1. Threaded grooves 13 are opened on the outer barrel 1. A cover 14 is provided on the top surface of the outer barrel 1. Anti-slip grooves are opened on the cover 14. A reinforcing ring 15 is fixedly connected to the outer wall of the outer barrel 1. Two handles 16 are installed on the reinforcing ring 15. The outer wall of the outer barrel 1 is coated with a polyolefin modified layer. The inner wall of the inner barrel 3 is coated with a fluorocarbon layer.

[0021] Working Principle: During use, when the outer wall of the outer barrel 1 is subjected to compression and impact, the elastic column 7 is compressed inward under the force. When the external pressure is removed, the elastic column 7 recovers and resists pressure outward. The elastic column 7 has a high-strength buffering and rebound effect, enhancing impact resistance and deformation resistance. The elastic column 7 absorbs impact energy through compression deformation, converting localized concentrated stress into dispersed elasticity, achieving an anti-compression effect and enhancing practicality and flexibility. Then, under the action of the restoring inner core 5, the anti-compression effect of the outer wall of the outer barrel 1 is increased. When the double-layer plastic barrel is impacted and compressed, the restoring inner core 5 can absorb most of the impact energy through elastic deformation, reducing damage to the barrel structure, avoiding barrel wall dents or cracks, extending its service life, improving structural stability and durability, reducing maintenance and replacement costs, and improving overall strength. The baffle 10 can block the sloshing of liquid during the transportation of the plastic barrel, reducing the kinetic energy generated by the sloshing of liquid. The baffle 10 divides the liquid into different areas to restrict the flow of liquid, effectively reducing the amplitude of liquid sloshing in the barrel, improving transportation stability, enhancing flexibility, and improving safety.
