[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1: Please refer to Figure 1-Figure 4 The present invention provides a technical solution: a chemical product packaging barrel, comprising: a barrel body 1 and a barrel cover 5, an inner top ring 4 is provided on the inner wall of the top of the barrel body 1, a barrel cover 5 is provided on the outer side of the inner top ring 4, an outer thread is provided on the outer wall of the inner top ring 4, and an inner thread is provided inside the barrel cover 5 to match the inner top ring 4. Liquid chemical products are often corrosive, flammable or toxic, so it is very important to ensure the sealing of the packaging barrel. The use of internal and external threads ensures a tight connection between the barrel cover and the barrel body, effectively preventing the leakage of liquid chemical products. As the supporting part for the connection between the barrel cover and the barrel body, the design of the inner top ring enhances the stability and sealing of the connection.

[0031] A pressing ring 7 is provided on the top of the barrel cover 5, a buckle hook 8 is provided on the outer wall of the pressing ring 7, and a buckle body 3 is provided on the outer wall of the top of the barrel body 1. The design of the pressing ring and the buckle further enhances the connection strength between the barrel cover and the barrel body, and can maintain a stable connection even under bumpy transportation conditions. The design of the pressing ring 7 and the buckle structure (the buckle hook 8 and the buckle body 3) makes the opening and closing of the barrel cover more convenient and quick, and also improves the sealing and safety of the packaging barrel. The strength of the buckle connection comes from the mechanical internal lock and friction, which ensures the firmness of the barrel cover during transportation and prevents the risk of leakage caused by looseness.

[0032] A conical shell 9 is provided in the center of the inner wall of the barrel cover 5, and a strip groove 10 is provided inside the conical shell 9. During transportation, the packaging barrel may be subjected to bumps and collisions, causing the liquid chemical products inside to shake, or even impact the barrel cover. In order to avoid this situation, the conical shell 9 and the strip groove 10 are designed as wave-breaking plates. The structure of the conical shell 9 and the strip groove 10 can disperse the impact force of the liquid and reduce its direct impact on the barrel cover, thereby maintaining the stability of the packaging barrel during transportation. When the chemical product packaging barrel contains liquid chemical products, sealing is achieved through the threaded connection between the barrel cover 5 and the barrel body 1. When the liquid chemical products are transported, the shaking caused by the bumps is buffered by the conical shell 9 and the strip groove 10 as wave-breaking plates to avoid direct impact on the barrel cover 5.

[0033] The design of the conical shell gives it better fluid dynamics, which can effectively disperse and mitigate the impact force of liquid chemical products caused by bumps during transportation. The strip grooves further increase the internal resistance of the liquid during the shaking process, reduce the direct impact of the liquid, and thus enhance the wave-proof effect. The structural design of the conical shell and the strip grooves gives the entire wave-proof board a higher structural strength, which can withstand greater impact without being easily damaged. This design also increases the overall stability of the packaging barrel, making it more adaptable to various complex transportation environments. The structure of the conical shell and the strip grooves is relatively simple and easy to clean. Even if there are sediments or impurities in the liquid chemical products, they can be removed by simple operations, ensuring the long-term use of the packaging barrel.

[0034] There are eight buckle hooks 8, which are evenly arranged circumferentially on the outer wall of the pressure ring 7. There are eight buckle bodies 3, which are evenly arranged circumferentially on the outer wall of the barrel body 1. When the buckle body 3 is locked with the buckle hooks 8, the pressure ring 7 generates pressure on the rotary cover 6 in the direction of the barrel body 1. The circumferential uniform arrangement of the eight buckle hooks 8 and the eight buckle bodies 3 ensures that when they are locked, the pressure can be evenly distributed between the pressure ring 7 and the barrel body 1. This evenly distributed pressure helps to enhance the sealing between the barrel cover and the barrel body and prevent the leakage of liquid chemical products. The setting of multiple buckle points makes the connection between the barrel cover and the barrel body more stable. Even if there is bumps or vibrations during transportation, the connection between the barrel cover and the barrel body is not easy to loosen or damage because multiple buckle points are subjected to force at the same time, thereby improving the stability of the packaging barrel.

[0035] The number of buckle hooks 8 and buckle bodies 3 is reasonably designed, so that the barrel cover can be quickly and conveniently locked or loosened during operation. This design improves work efficiency and reduces the difficulty of operation. The tight locking of eight buckle hooks 8 and eight buckle bodies 3 ensures the safety of the packaging barrel during transportation and storage. Even in the event of unexpected situations, such as collision or falling, the firm connection between the barrel cover and the barrel body can effectively prevent the leakage of liquid chemical products, thereby reducing safety risks. When the buckle body 3 is locked with the buckle hook 8, the pressure ring 7 will exert pressure on the rotary cover 6 in the direction of the barrel body 1. This pressure not only enhances the sealing between the barrel cover and the barrel body, but also prevents the rotary cover 6 from loosening or falling off due to vibration during transportation.

[0036] A buffer ring 2 is provided on the outer wall of the middle part of the barrel body 1, and the buffer ring 2 is made of rubber. The buffer ring 2 made of rubber has good elasticity and buffering performance. During transportation, the packaging barrel may be subjected to various impacts and vibrations, and the buffer ring 2 can effectively absorb these impact energies, reduce damage to the barrel body, and thus protect the safety of the chemical products in the barrel. The design of the buffer ring 2 increases the friction between the barrel body 1 and other barrel bodies, and improves the stability of the packaging barrel. Even on uneven ground or bumpy transportation conditions, the packaging barrel can remain relatively stable, reducing the risk of leakage of liquid chemical products caused by shaking.

[0037] The rubber material has good sound insulation performance. During transportation, the collision and friction of the packaging barrel will generate noise, and the buffer ring 2 can effectively reduce this noise and reduce the impact on the surrounding environment and personnel. The buffer ring 2 can reduce the damage to the barrel body 1 during transportation and storage, thereby extending the service life of the packaging barrel. At the same time, the rubber material has good corrosion resistance, can resist the erosion of various chemical substances, and maintain the long-term stability of the packaging barrel. By enhancing impact resistance and improving stability, the buffer ring 2 further improves the safety of chemical product packaging barrels. Even under harsh transportation conditions, it can effectively prevent the leakage and damage of liquid chemical products, ensuring the safety of personnel and the environment.

[0038] The end with a larger diameter at the top of the conical shell 9 is connected to the barrel cover 5. The top of the conical shell 9 is provided with an internal thread, the bottom of the barrel cover 5 is provided with a convex ring, and the outer wall of the convex ring is provided with an external thread that matches the conical shell 9. The design of the internal and external threads makes the connection between the conical shell 9 and the barrel cover 5 both tight and easy to operate. The staff can easily install and disassemble it for easy inspection, cleaning and maintenance of the packaging barrel.

[0039] Example 2: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: a chemical product packaging barrel, comprising: a barrel body 1 and a barrel cover 5, an inner top ring 4 is provided on the inner wall of the top of the barrel body 1, a barrel cover 5 is provided on the outer side of the inner top ring 4, an outer thread is provided on the outer wall of the inner top ring 4, and an inner thread is provided inside the barrel cover 5 to match the inner top ring 4. Liquid chemical products are often corrosive, flammable or toxic, so it is very important to ensure the sealing of the packaging barrel. The use of internal and external threads ensures a tight connection between the barrel cover and the barrel body, effectively preventing the leakage of liquid chemical products. As the supporting part for the connection between the barrel cover and the barrel body, the design of the inner top ring enhances the stability and sealing of the connection.

[0040] A pressing ring 7 is provided on the top of the barrel cover 5, a buckle hook 8 is provided on the outer wall of the pressing ring 7, and a buckle body 3 is provided on the outer wall of the top of the barrel body 1. The design of the pressing ring and the buckle further enhances the connection strength between the barrel cover and the barrel body, and can maintain a stable connection even under bumpy transportation conditions. The design of the pressing ring 7 and the buckle structure (the buckle hook 8 and the buckle body 3) makes the opening and closing of the barrel cover more convenient and quick, and also improves the sealing and safety of the packaging barrel. The strength of the buckle connection comes from the mechanical internal lock and friction, which ensures the firmness of the barrel cover during transportation and prevents the risk of leakage caused by looseness.

[0041] A conical shell 9 is provided in the center of the inner wall of the barrel cover 5, and a strip groove 10 is provided inside the conical shell 9. During transportation, the packaging barrel may be subjected to bumps and collisions, causing the liquid chemical products inside to shake, or even impact the barrel cover. In order to avoid this situation, the conical shell 9 and the strip groove 10 are designed as wave-breaking plates. The structure of the conical shell 9 and the strip groove 10 can disperse the impact force of the liquid and reduce its direct impact on the barrel cover, thereby maintaining the stability of the packaging barrel during transportation. When the chemical product packaging barrel contains liquid chemical products, sealing is achieved through the threaded connection between the barrel cover 5 and the barrel body 1. When the liquid chemical products are transported, the shaking caused by the bumps is buffered by the conical shell 9 and the strip groove 10 as wave-breaking plates to avoid direct impact on the barrel cover 5.

[0042] There are eight buckle hooks 8, which are evenly arranged circumferentially on the outer wall of the pressure ring 7. There are eight buckle bodies 3, which are evenly arranged circumferentially on the outer wall of the barrel body 1. When the buckle body 3 is locked with the buckle hooks 8, the pressure ring 7 generates pressure on the rotary cover 6 in the direction of the barrel body 1. The circumferential uniform arrangement of the eight buckle hooks 8 and the eight buckle bodies 3 ensures that when they are locked, the pressure can be evenly distributed between the pressure ring 7 and the barrel body 1. This evenly distributed pressure helps to enhance the sealing between the barrel cover and the barrel body and prevent the leakage of liquid chemical products. The setting of multiple buckle points makes the connection between the barrel cover and the barrel body more stable. Even if there is bumps or vibrations during transportation, the connection between the barrel cover and the barrel body is not easy to loosen or damage because multiple buckle points are subjected to force at the same time, thereby improving the stability of the packaging barrel.

[0043] The number of buckle hooks 8 and buckle bodies 3 is reasonably designed, so that the barrel cover can be quickly and conveniently locked or loosened during operation. This design improves work efficiency and reduces the difficulty of operation. The tight locking of eight buckle hooks 8 and eight buckle bodies 3 ensures the safety of the packaging barrel during transportation and storage. Even in the event of unexpected situations, such as collision or falling, the firm connection between the barrel cover and the barrel body can effectively prevent the leakage of liquid chemical products, thereby reducing safety risks. When the buckle body 3 is locked with the buckle hook 8, the pressure ring 7 will exert pressure on the rotary cover 6 in the direction of the barrel body 1. This pressure not only enhances the sealing between the barrel cover and the barrel body, but also prevents the rotary cover 6 from loosening or falling off due to vibration during transportation.

[0044] A buffer ring 2 is provided on the outer wall of the middle part of the barrel body 1, and the buffer ring 2 is made of rubber. The buffer ring 2 made of rubber has good elasticity and buffering performance. During transportation, the packaging barrel may be subjected to various impacts and vibrations, and the buffer ring 2 can effectively absorb these impact energies, reduce damage to the barrel body, and thus protect the safety of the chemical products in the barrel. The design of the buffer ring 2 increases the friction between the barrel body 1 and other barrel bodies, and improves the stability of the packaging barrel. Even on uneven ground or bumpy transportation conditions, the packaging barrel can remain relatively stable, reducing the risk of leakage of liquid chemical products caused by shaking.

[0045] The rubber material has good sound insulation performance.

The buffer ring 2 can reduce the damage to the barrel body 1 during transportation and storage, thereby extending the service life of the packaging barrel. At the same time, the rubber material has good corrosion resistance, can resist the erosion of various chemical substances, and maintain the long-term stability of the packaging barrel. By enhancing impact resistance and improving stability, the buffer ring 2 further improves the safety of chemical product packaging barrels. Even under harsh transportation conditions, it can effectively prevent the leakage and damage of liquid chemical products, ensuring the safety of personnel and the environment.

[0046] The end with a larger diameter at the top of the conical shell 9 is connected to the barrel cover 5. The top of the conical shell 9 is provided with an internal thread, the bottom of the barrel cover 5 is provided with a convex ring, and the outer wall of the convex ring is provided with an external thread that matches the conical shell 9. The design of the internal and external threads makes the connection between the conical shell 9 and the barrel cover 5 both tight and easy to operate. The staff can easily install and disassemble it for easy inspection, cleaning and maintenance of the packaging barrel.

[0047] In this embodiment, a polygonal column 11 is provided at the center of the bottom of the conical shell 9, a limit block 12 is provided at the bottom of the polygonal column 11, a connecting plate 13 is provided at the top of the polygonal column 11, and a sealing sheet 14 is provided on the outer wall of the connecting plate 13.

[0048] There are multiple strip grooves 10, which are evenly arranged circumferentially inside the conical shell 9, and the strip grooves 10 are arranged vertically. There are multiple sealing sheets 14, which are evenly arranged circumferentially on the outer wall of the connecting plate 13. The number of sealing sheets 14 is the same as the number of strip grooves 10, and the size of the sealing sheet 14 is larger than the size of the strip groove 10. One side of the sealing sheet 14 fits the inner wall of the conical shell 9. When the liquid impacts the conical shell 9, it will impact the sealing sheet 14 on one side of the strip groove 10. The impact force of the liquid will cause the sealing sheet 14 to produce a certain elastic deformation, thereby reducing the impact force of the liquid. In addition, the impact force of the liquid will drive the sealing sheet 14 to generate an upward force, so that the sealing sheet 14 and the connecting plate 13 rise under the guidance of the polygonal column 11, and the impact force is reduced by the displacement of the sealing sheet 14.

[0049] A V-shaped plate 17 is provided on one side of the upper half of the sealing sheet 14, an inner plate 15 is provided between the V-shaped plates 17, and a counterweight 16 is provided on the top of the inner plate 15. There are a plurality of V-shaped plates 17, and the plurality of V-shaped plates 17 are evenly arranged in the circumferential direction on the outer wall of the inner plate 15. The impact force is mitigated by the displacement of the sealing sheet 14. Furthermore, the elastic deformation of the sealing sheet 14 can be adjusted by the elastic force of the V-shaped plates 17 between the upper halves of the sealing sheet 14 in conjunction with the counterweight, so that the sealing sheet 14 can be quickly reset after being deformed by impact, which is convenient for buffering the subsequent impact force, ensuring that the liquid will not cause a large direct impact on the barrel cover 5, and improving the sealing and safety of the entire packaging barrel.

[0050] An outer flange is provided at the bottom end of the inner top ring 4, and the outer flange is fixedly connected to the inner wall of the barrel body 1. The distance between the outer wall of the inner top ring 4 and the inner wall of the barrel body 1 is greater than the thickness of the barrel cover 5. A screw cap 6 is fixed on the top of the barrel cover 5. The screw cap 6 is annular, and the inner and outer rings of the screw cap 6 are provided with anti-slip grooves. A pressure ring 7 is arranged above the screw cap 6.

[0051] When the chemical product packaging barrel contains liquid chemical products, the barrel cover 5 is sealed by threaded connection with the barrel body 1. When the liquid chemical product is transported, the shaking caused by the bumps is buffered by the conical shell 9 and the strip groove 10 as wave-breaking plates to avoid direct impact on the barrel cover 5. In addition, when the liquid impacts the conical shell 9, it will impact the sealing sheet 14 on one side of the strip groove 10. The impact force of the liquid will cause the sealing sheet 14 to produce a certain elastic deformation, thereby slowing down the impact force of the liquid. In addition, the impact force of the liquid will bring The dynamic sealing sheet 14 generates an upward force, so that the sealing sheet 14 and the connecting plate 13 rise under the guidance of the polygonal column 11, and the impact force is mitigated by the displacement of the sealing sheet 14. Furthermore, the elastic force of the V-shaped plate 17 between the upper halves of the sealing sheet 14, in conjunction with the counterweight block, can adjust the elastic deformation of the sealing sheet 14, so that the sealing sheet 14 can be quickly reset after being deformed by an impact, which is convenient for buffering subsequent impact forces, ensuring that the liquid will not cause a large direct impact on the barrel cover 5, thereby improving the sealing and safety of the entire packaging barrel.
