Description

Technical Field

[0001] This utility model relates to the field of open-top barrel technology, and in particular to a reinforced open-top barrel. Background Technology

[0002] Open-top containers are cylindrical or square containers with an openable top, primarily used for the storage and transport of liquids, solids, or hazardous chemicals. Materials include metals (such as iron and galvanized steel) and plastics (such as polyethylene and HDPE). Traditional open-top containers suffer from insufficient structural strength, poor sealing, and susceptibility to deformation. For example, ordinary open-top steel drums are manufactured using a single steel plate rolling process. Due to the lack of targeted reinforcement design in the drum opening area, this area is prone to deformation under transport vibration or drop impacts, directly affecting sealing performance and service life. While some existing technologies attempt to improve strength by forming a ring-shaped reinforcing rib structure on the drum body at the opening through mechanical rolling, the strength is still insufficient. Therefore, a reinforced open-top container is proposed to address the problems existing in the current technology. Utility Model Content

[0003] The purpose of this invention is to provide a reinforced open barrel to solve the problem that the strength of the opening area of ​​steel barrels in the prior art is insufficient, which makes the opening area prone to deformation under transportation vibration or drop impact, directly affecting the sealing performance and service life.

[0004] The technical solution of this utility model is: a reinforced open bucket, comprising: a bucket body and a bucket lid that can be detachably fitted onto the opening of the bucket body; the bucket body is a container with a gradually changing cross-section and an opening at the top.

[0005] The cross-section of the barrel gradually narrows from top to bottom along the axial direction, forming a cone-shaped structure that is wider at the top and narrower at the bottom;

[0006] The upper end of the barrel is provided with a radially outward protruding reinforcing rib, which is integrally formed with the barrel body;

[0007] The upper end of the barrel is fitted with a reinforcing hoop, and the axial positioning range of the reinforcing hoop is 15-25 cm below the barrel opening.

[0008] Preferably, the vertical cross-section of the reinforcing hoop is a continuous curve or broken line configuration with the opening facing the barrel body, including but not limited to any one of C-shape, U-shape, and V-shape, and the reinforcing hoop is fixed to the barrel body by welding process.

[0009] Preferably, there are multiple reinforcing ribs, and the vertical cross-section of each reinforcing rib is V-shaped; the reinforcing hoop is located below the multiple reinforcing ribs.

[0010] Preferably, the barrel body includes a barrel body with a circular cross-section and a cap-shaped barrel bottom, wherein the barrel bottom includes an upwardly protruding central circular boss;

[0011] The reinforcing ribs and reinforcing hoops are all circular.

[0012] Preferably, the bucket lid includes a central conical boss that is narrower at the top and wider at the bottom, and a lip that extends circumferentially from the central conical boss and hangs on the bucket body, wherein the central conical boss has an annular conical surface.

[0013] Preferably, the lower end of the barrel body and the edge of the central circular boss are formed into a multi-layer rolled edge structure by a rolling edge process. The multi-layer rolled edge structure includes multiple layers of barrel body material and barrel bottom material that are alternately stacked. A continuously distributed sealing medium layer is provided between adjacent barrel body material layers and barrel bottom material layers. The sealing medium layer seals the barrel body material layer and barrel bottom material layer by rolling edge pressure.

[0014] Preferably, when the two reinforced open buckets with their lids closed are stacked one on top of the other, the multi-layer rolled edge structure of the upper reinforced open bucket presses against the annular conical surface, and the central conical boss portion is accommodated in the cavity formed by the central circular boss.

[0015] Preferably, the bucket lid is detachably fitted onto the bucket opening via a bucket hoop, and a sealing ring is installed at the contact portion between the bucket lid and the bucket opening.

[0016] Preferably, the barrel hoop includes an open hoop ring and a locking element for locking the hoop ring.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] (1) A reinforced open bucket of the present invention includes a bucket body and a bucket lid that can be detachably fitted to the bucket mouth of the bucket body; the upper end of the bucket body is provided with a radially outward protruding reinforcing rib, which is integrally formed with the bucket body; the upper end of the bucket body is fitted with a reinforcing hoop; the reinforcing hoop wraps around the bucket mouth area through a ring structure to form a closed ring support frame, effectively dispersing the concentrated stress generated when falling or being squeezed, resisting radial deformation, and forming a double layer of protection in conjunction with the reinforcing rib of the bucket body to suppress the risk of bucket mouth deformation.

[0019] (2) In this utility model, when two barrels are nested and stacked, the top of the opening of the lower barrel abuts against the reinforcing hoop of the upper barrel. The reinforcing hoop is set 15-25 cm below the opening of the barrel. This can not only ensure that the strength of the opening of the barrel is improved, but also ensure that the overall height of the nested and stacked barrels is low, thereby improving the space utilization of the container.

[0020] (3) In this utility model, the cross-section of the barrel body gradually narrows from top to bottom along the axial direction to form a cone structure that is wider at the top and narrower at the bottom. This allows the barrels to be stacked inside each other during transportation, saving transportation space. Attached Figure Description

Therefore, they should not be construed as limitations on the utility model.

[0030] like Figure 1 , Figure 2As shown, a reinforced open-top barrel includes: a barrel body and a barrel lid 1 that can be detachably fitted onto the barrel opening; the barrel lid 1 is detachably fitted onto the barrel opening via a barrel hoop, and a sealing ring is installed at the contact portion between the barrel lid 1 and the barrel opening. The barrel hoop includes an open hoop ring 2 and a locking element 3 for locking the hoop ring 2. The barrel body is a container with a gradually changing cross-section and an open top; the cross-section of the barrel body gradually narrows from top to bottom along the axial direction, forming a conical structure that is wider at the top and narrower at the bottom; a radially outwardly protruding reinforcing rib 4 is provided at the upper end of the barrel body, and the reinforcing rib 4 is integrally formed with the barrel body; a reinforcing hoop 5 is fitted at the upper end of the barrel body, and the axial positioning range of the reinforcing hoop 5 is 15-25 cm below the barrel opening. The cross-section of the barrel body gradually narrows from top to bottom along the axial direction, forming a conical structure that is wider at the top and narrower at the bottom, which allows for nested stacking of reinforced open-top barrels during transportation, saving transportation space. In this embodiment, the independently set reinforcing hoop 5 achieves structural reinforcement without changing the yield strength of the material. The reinforcing hoop 5 provides circumferential wrapping support and converts radial expansion stress into circumferential compressive stress through mechanical constraint, thereby improving the deformation resistance of the barrel opening. Together with the reinforcing ribs 4 of the barrel body 6, it forms a double layer of protection to suppress the risk of barrel opening deformation.

[0031] like Figure 4 As shown, in this embodiment, the reinforced open barrel can be stacked nested within each other when transported without the barrel lid 1. When two barrels are stacked nested, the top of the lower barrel's opening rests against the reinforcing hoop 5 of the upper barrel. The reinforcing hoop 5 is located 15-25 cm below the barrel opening, which can both ensure a good increase in the strength of the barrel opening and ensure that the overall height of the nested barrels is low, thereby improving the utilization rate of container space.

[0032] The vertical cross-section of the reinforcing hoop 5 is a continuous curve or broken line configuration with its opening facing the barrel body, including but not limited to any one of C-shape, U-shape, and V-shape. The reinforcing hoop 5 is fixed to the barrel body by welding. There are multiple reinforcing ribs 4, and the vertical cross-section of the reinforcing ribs 4 is V-shaped; the reinforcing hoop 5 is located below the multiple reinforcing ribs 4.

[0033] The barrel body includes a circular cross-section barrel body 6 and a cap-shaped barrel bottom 7, the barrel bottom 7 including an upwardly protruding central circular boss 8; the reinforcing ribs 4 and reinforcing hoops 5 are both annular. The barrel lid 1 includes a central conical boss 9 that is narrower at the top and wider at the bottom, and a lip 10 that extends circumferentially from the central conical boss 9 and hangs on the barrel body 6. The central conical boss 9 has an annular conical surface 11. The lower end of the barrel body 6 and the edge of the central circular boss 8 form a multi-layer rolled edge structure through a rolling edge process. The multi-layer rolled edge structure includes multiple alternating layers of barrel body 6 material and barrel bottom 7 material; a continuously distributed sealing medium layer is provided between adjacent barrel body 6 material layers and barrel bottom 7 material layers, and the sealing medium layer achieves the seal between the barrel body 6 material layers and barrel bottom 7 material layers through the rolling edge pressure. When the two reinforced open buckets with lids 1 are stacked one on top of the other, the multi-layered rolled edge structure of the upper reinforced open bucket presses against the annular conical surface 11, and the central conical protrusion 9 is partially accommodated in the cavity formed by the central circular protrusion 8. In this embodiment, as... Figure 3 , Figure 4 As shown, the structure of the barrel bottom 7 and the barrel lid 1 enables the reinforced open barrels to be stacked after the barrel lid 1 is placed on them. The barrel bottom 7 and the barrel lid 1 have a good fit, which prevents slippage and increases stability, saving space occupied by batch reinforced open barrels.
