Description

Technical Field

[0001] This utility model relates to the field of barrel-shaped container technology, and in particular to a stackable straight-sided open barrel. Background Technology

[0002] Steel drums are standard cylindrical containers made of steel (such as cold-rolled steel plates, tin-plated steel plates, etc.) as the base material, through processes such as rolling, welding, flanging, and sealing. They belong to an important category of metal packaging containers and have the characteristics of high strength and good sealing performance. They are mainly used to hold liquids, semi-solids, or solid materials.

[0003] The stackable design of steel drums has significant value in improving warehousing and logistics efficiency. Unitized stacking can improve space utilization and reduce operating costs. For example, forklifts can transport 4-6 steel drums at a time, avoiding the handling of individual drums and reducing loading and unloading time. Moreover, stacking steel drums reduces the need for additional reinforcement brackets and other protective materials. In existing technologies, steel drums are usually stacked by setting the drum body to a conical shape that is wider at the top and narrower at the bottom, or by making it into a narrow-mouthed drum with a smaller top opening. Both methods can achieve stacking of steel drums. However, making the drum body into an irregular shape is more complex than the production process of straight drums. How to make straight steel drums stackable is an urgent problem to be solved. This paper proposes a stackable straight-mouthed drum to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a stackable straight-sided open drum to solve the problem of existing straight-sided steel drums that cannot be stacked.

[0005] The technical solution of this utility model is: a stackable straight-sided open barrel, comprising: a barrel body in the shape of a straight cylindrical column, a barrel bottom sealed and fixed at the lower end port of the barrel body, and a barrel lid that can be detachably covered at the upper end port of the barrel body by means of a clamp;

[0006] The clamp is wrapped around the outer surface of the axial body of the bucket lid, and its structure includes an open clamp and a locking member for locking the clamp.

[0007] The bottom of the bucket includes a bottom body that is concave and opens downwards;

[0008] When the two straight-sided open barrels with their lids closed are stacked one on top of the other, the hoop of the lower straight-sided open barrel and the bottom of the upper straight-sided open barrel form a nested load-bearing structure.

[0009] Preferably, the hoop includes a clamping ring with an inward opening and a horizontally inverted V-shaped vertical cross-section, and a positioning ring extending upward from the upper edge of the clamping ring as a base point;

[0010] The edges of the bottom body of the bucket and the lower edge of the bucket body are rolled together to form a multi-layer rolled edge structure;

[0011] When the two straight-sided open buckets are stacked together with their lids closed, the multi-layer rolled edge structure of the upper straight-sided open bucket is supported on the clamping ring of the lower straight-sided open bucket, and the positioning ring of the lower straight-sided open bucket is housed inside the bottom body of the upper straight-sided open bucket.

[0012] Preferably, the positioning ring is conical in shape, narrower at the top and wider at the bottom;

[0013] The bottom of the barrel is shaped like a straight, upward-convex cap.

[0014] Preferably, the barrel body includes an upper edge portion and a straight cylindrical barrel body portion connected sequentially from top to bottom.

[0015] Preferably, the upper edge portion is formed by a single-layer rolled edge with a vertical annular cross-section.

[0016] Preferably, the cylindrical barrel portion is symmetrically provided with multiple radially outward protruding reinforcing ribs on its upper and lower sides, and the multiple reinforcing ribs are integrally formed with the cylindrical barrel portion.

[0017] Preferably, the multi-layer rolled edge structure is a seven-layer rolled edge structure, which includes alternating layers of barrel body material and barrel bottom material; a continuously distributed sealing medium layer is provided between adjacent barrel body material layers and barrel bottom material layers, and the sealing medium layer seals the barrel body material layer and barrel bottom material layer through the rolling edge pressure.

[0018] Preferably, the bucket lid includes a concave bucket lid body that is wider at the top and narrower at the bottom, and a V-shaped hanging lug that extends circumferentially from the edge of the bucket lid body and hangs on the rolled edge.

[0019] Preferably, a sealing ring is installed at the contact portion between the hanging ear and the upper rolled edge.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] (1) A stackable straight-sided open bucket of the present invention includes: a straight cylindrical barrel body, a barrel bottom sealed and fixed at the lower end port of the barrel body, and a barrel lid detachably covered at the upper end port of the barrel body by a clamp; the clamp covers the outer surface of the axial body of the barrel lid, and its structure includes an open clamp ring and a locking member for locking the clamp ring; the barrel bottom includes a barrel bottom body with a downward opening and a recessed shape; the clamp ring includes a clamping ring with an inward opening and a horizontal inverted V-shaped vertical cross section, and a positioning ring extending upward from the upper edge of the clamping ring as the base point; in this embodiment, the straight-sided open bucket is stackable through the structure of the clamp ring and the barrel bottom, and the straight cylindrical barrel body of the straight-sided open bucket is simple to produce and has a lower production cost than irregularly shaped buckets. In this embodiment, by setting the positioning ring on the clamp ring, the radial positioning of the upper and lower straight-sided open buckets is achieved through the nesting cooperation between the positioning ring and the barrel bottom body, preventing slippage during stacking.

[0022] (2) A stackable straight open barrel in this utility model has a positioning ring that is narrow at the top and wide at the bottom in the shape of a cone. It has a sloping guiding function. The cone shape allows the upper straight open barrel to be automatically aligned and placed on the clamping ring of the lower straight open barrel even if there is a deviation in the placement position.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] like Figure 1 , Figure 2 As shown, a stackable straight-sided open barrel includes: a barrel body 1 in the shape of a straight cylindrical column, a barrel bottom 2 sealed and fixed at the lower end port of the barrel body 1, and a barrel lid 3 detachably covered at the upper end port of the barrel body 1 by means of a clamp 4; the clamp 4 covers the outer surface of the axial body of the barrel lid 3, and its structure includes an open clamp ring 5 and a locking member 6 for locking the clamp ring 5; the barrel bottom 2 includes a barrel bottom body 7 with a downward opening and recess; when two straight-sided open barrels with the barrel lid 3 closed are stacked one on top of the other, the clamp ring 5 of the lower straight-sided open barrel and the barrel bottom 2 of the upper straight-sided open barrel form a nested load-bearing structure.

[0033] The hoop 5 includes a clamping ring 8 with its opening facing inward and a horizontally inverted V-shaped vertical cross-section, and a positioning ring 9 extending upward from the upper edge of the clamping ring 8; the edge of the barrel bottom body 7 and the lower edge of the barrel body 1 are rolled together to form a multi-layer rolled edge structure; such as Figure 5 As shown, when two straight-sided open-top buckets with lids 3 closed are stacked, the multi-layer rolled edge structure of the upper straight-sided open-top bucket is supported by the clamping ring 8 of the lower straight-sided open-top bucket, and the positioning ring 9 of the lower straight-sided open-top bucket is housed inside the bottom body 7 of the upper straight-sided open-top bucket. The positioning ring 9 is conical in shape, narrow at the top and wide at the bottom, and has a sloping guiding function. The conical shape allows the upper straight-sided open-top bucket to be automatically aligned and placed on the clamping ring 8 of the lower straight-sided open-top bucket even if the placement position is deviated. The bottom body 7 is a straight-sided cap shape with an upward convex shape. In this embodiment, the stackability of straight-sided open-top buckets is achieved through the structure of the clamp 4 and the bottom 2. The straight cylindrical body 1 of the straight-sided open-top bucket is simple to produce and has a lower production cost than irregularly shaped buckets. In this embodiment, by setting the positioning ring 9 on the clamp 5, the radial positioning of the upper and lower straight-sided open-top buckets is achieved through the nesting cooperation between the positioning ring 9 and the bottom body 7, preventing slippage during stacking.

[0034] The barrel body 1 includes, from top to bottom, an upper edge portion and a straight cylindrical barrel body portion 11. For example... Figure 3As shown, the upper edge is formed by a single-layer rolled edge, resulting in an upper rolled edge 10 with a vertical annular cross-section. Multiple radially protruding reinforcing ribs 12 are symmetrically arranged on the upper and lower sides of the cylindrical barrel portion 11, and these reinforcing ribs 12 are integrally formed with the cylindrical barrel portion 11. In this embodiment, the radially protruding reinforcing ribs 12 can improve the deformation resistance of the cylindrical barrel portion 11.

[0035] like Figure 4 As shown, the multi-layer rolled edge structure is a seven-layer rolled edge structure, which includes alternating layers of barrel body material and barrel bottom material. A continuously distributed sealing medium layer is provided between adjacent barrel body material layers and barrel bottom material layers. The sealing medium layer achieves a seal between the barrel body material layer and the barrel bottom material layer through the rolling edge pressure. Figure 3 As shown, the bucket lid 3 includes a concave, cone-shaped lid body 13 that is wider at the top and narrower at the bottom, and a V-shaped hanging lug 14 that extends circumferentially from the edge of the lid body 13 and hangs on the upper rolled edge 10. A sealing ring 15 is installed at the contact portion between the hanging lug 14 and the upper rolled edge.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
