Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to an anti-collision plastic barrel. Background Art

[0002] Plastic barrels are mostly used for the storage and transportation of various liquids and have good properties for the packaging of special hazardous materials. They are not easy to break, rust-proof, and lightweight. They are also oil-resistant and highly corrosion-resistant. They are mostly used for the packaging of hazardous materials that require insulation, moisture-proof, pressure-resistant, and corrosion-resistant. The widely used plastic barrels currently include a barrel body and a barrel cover. The barrel body is a cylindrical structure with one side open. The diameter of the open side of the barrel body is larger than the diameter of the other side of the barrel body, thereby making the barrel body structure more stable. However, the barrel body structure with a thick top and a thin bottom has poor anti-collision effect and is easily damaged due to collision, resulting in poor sealing and easily causing safety accidents. In the prior art, in order to improve safety performance, it is usually necessary to set an anti-collision device on the outside of the plastic barrel. For example, Chinese patent document CN202020747454.6 discloses an anti-collision plastic barrel, including a barrel body and a barrel cover. The barrel body includes an outer barrel body and an inner barrel body. A buffer layer is provided between the inner barrel body and the outer barrel body, and a buffer pad is provided on the lower surface of the outer barrel body. A base is fixedly provided on the lower surface of the buffer pad. An anti-collision component is provided on the outer wall of the outer barrel body, and a plurality of anti-collision particles are provided on the outer wall of the outer barrel body. A copper column with a T-shaped vertical cross-section is provided on the bottom surface of the inner barrel body, an exhaust pipe is provided on the barrel cover, and a pressure relief valve is provided in series in the exhaust pipe. Although the double-layer barrel structure and the buffer layer provided between the inner barrel body and the outer barrel body adopted in the above patent can improve the anti-collision performance of the plastic barrel, its manufacturing difficulty is high, the manufacturing cost is high, and the anti-collision is not targeted.

For a barrel structure that is thick at the top and thin at the bottom, the collision-resistant parts are concentrated on the barrel structure with a larger diameter, so as to specifically improve the collision-resistant performance and reduce the production cost and difficulty.

DETAILED DESCRIPTION

[0019] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0020] Example 1:

[0021] See also Figure 1 、 Figure 2 The present invention provides an anti-collision plastic barrel, including a barrel body 10, which is a conical cylindrical structure with a hollow interior. The diameter of the upper part of the barrel body 10 is larger than the diameter of the lower part. The structure of being wide at the top and narrow at the bottom is used to reduce the impact area; the top of the barrel body 10 is provided with a curved surface 18, which is arranged at the position where the diameter of the barrel body 10 is the largest. The bottom surface of the barrel body 10 is provided with a groove 19, which is disc-shaped and opens inward from the bottom surface of the barrel body 10. The curved surface 18 is used to ensure that when the barrel body 10 is hit, the impact force is distributed more evenly to prevent sharp parts from piercing and damaging it. The groove 19 is used to improve the stability of the barrel body 10 when it is placed.

[0022] Furthermore, the barrel body 10 is provided with a handle 12 and an open mouth 11 at the top. An inner cavity 14 is formed inside the barrel body 10. The open mouth 11 passes through the top wall of the barrel body 10 and is connected to the inner cavity 14. The open mouth 11 is a cylindrical structure, one end of which is higher than the top surface of the barrel body 10. The outer wall of the end of the open mouth 11 is provided with an external thread, and the end of the open mouth 11 is threadedly connected to a sealing cover 13. The sealing cover 13 is sleeved on the end of the open mouth 11, and a first sealing gasket 16 is provided between the inner wall of the sealing cover 13 and the end surface of the open mouth 11. One side of the first sealing gasket 16 abuts the open mouth 11, and the other side of the first sealing gasket 16 can abut the sealing cover 13. At the same time, a second sealing gasket 17 is provided on the outer cover of the open mouth 11. The second sealing gasket 17 is located between the sealing cover 13 and the top wall of the barrel body 10 and can abut the sealing cover 13. The present invention ensures the sealing stability of the barrel body 10 by providing two sealing gaskets inside and outside. During use, first put the second sealing gasket 17 on the outside of the opening mouth 11, then place the first sealing gasket 16 on the end face of the opening mouth 11, put the sealing cover 13 on the opening mouth 11 and tighten it, the inner wall of the sealing cover 13 squeezes the first sealing gasket 16 onto the end face of the opening mouth 11, and the outer wall of the sealing cover 13 squeezes the second sealing gasket 17 onto the top of the barrel body 10, thereby ensuring the sealing effect and improving the stability of use.

[0023] In this embodiment, the first sealing gasket 16 and the second sealing gasket 17 are both made of rubber to ensure sealing stability.

[0024] Furthermore, the inner cavity 14 is divided from top to bottom into an upper inner cavity 141 and a lower inner cavity 142. The upper inner cavity 141 is cylindrical, and the lower inner cavity 142 is conical, wider at the top and narrower at the bottom. The diameter of the upper inner cavity 141 is greater than the diameter of the lower inner cavity 142. As a result, the wall thickness of the barrel body 10 in the upper inner cavity 141 is greater than the wall thickness of the barrel body 10 in the lower inner cavity 142.

[0025] A buffer cavity 15 is provided in the wall of the barrel body 10 at the arc surface 18, and the buffer cavity 15 includes an upper buffer cavity 151 and a lower buffer cavity 152. The upper buffer cavity 151 is arc-shaped and faces the arc surface 18. Part of the upper buffer cavity 151 extends to the top of the barrel body 10, and the other part of the upper buffer cavity 151 extends to the side of the barrel body 10. The curvature of the upper buffer cavity 151 is consistent with the curvature of the arc surface 18. The lower buffer cavity 152 is strip-shaped and is located below the upper buffer cavity 151.

[0026] The upper buffer cavity 151 is located at the part with the largest diameter of the barrel body 10. When in use, the upper buffer cavity 151 is used to improve the impact resistance of the barrel body 10, so that the part most prone to collision can buffer the impact, thereby improving the stability and safety of use. At the same time, a lower buffer cavity 152 is provided below the upper buffer cavity 151 to increase the buffering area and absorb the deformation from the upper buffer cavity 151, thereby further improving the impact resistance of the present invention.

[0027] The present invention provides an anti-collision structure for a plastic barrel that is wide at the top and narrow at the bottom. An upper inner cavity 141 and a lower inner cavity 142 are arranged inside the barrel body 10. By setting the inner diameters of the upper inner cavity 141 and the lower inner cavity 142, the wall thickness of the barrel body 10 in the upper inner cavity 141 is greater than the wall thickness of the barrel body 10 in the lower inner cavity 142. At the same time, a buffer cavity 15 is arranged at the part with the largest thickness and the largest outer diameter of the barrel body 10, so that the part most prone to collision can buffer the impact, thereby improving the stability and safety of use. At the same time, the buffer cavity 15 is placed in the wall of the barrel body 10, effectively ensuring the stability of the overall structure. The present invention divides the buffer cavity 15 into an upper buffer cavity 151 and a lower buffer cavity 152. The lower buffer cavity 152 is located below the upper buffer cavity 151 to increase the buffering area and absorb the deformation from the upper buffer cavity 151, thereby further improving the impact resistance of the present invention.

[0028] Example 2:

[0029] See also Figure 3 The anti-collision plastic barrel of the second embodiment of the present invention is different from the first embodiment in that the second embodiment adds an outer buffer cover 20 on the basis of the first embodiment, thereby changing the position of the buffer cavity 15 located in the wall of the barrel body 10.

[0030] The outer buffer cover 20 is snap-fitted and connected to the outer curved surface 18 of the barrel body 10. A recess is provided on the surface of the outer buffer cover 20 facing the barrel body 10. A buffer cavity 15 with a closed structure is formed between the recess and the outer wall of the barrel body 10. A closed structure is formed between the buffer cavity 15 and the outer wall of the barrel body 10 to protect the maximum diameter of the barrel body 10 and improve the buffering effect. Compared with Example 1, Example 2 adds an outer buffer cover 20 to the outside of the barrel body 10, and forms the buffer cavity 15 in a split manner, thereby reducing the manufacturing difficulty of the barrel body 10. At the same time, the operator can adaptively choose whether to install the outer buffer cover 20, thereby reducing production costs and improving usage flexibility.

[0031] In this embodiment, the outer buffer cover 20 can be snap-fitted and connected to the curved surface 18 of the barrel body 10 in a snap-fit ​​connection manner to ensure the stability of the connection.
