Abstract
Description
Technical Field
[0001] This utility model relates to the field of open-mouth barrel technology, and in particular to a straight-mouth open-mouth barrel with a reinforced structure. Background Technology
[0002] Patent document CN219258252U discloses a lid for an open-top can and an open-top can. This invention includes a lid body with at least one lid opening; a flange assembly located at the lid opening, comprising a first opening flange and a second opening flange. The first opening flange is connected to the lid opening and has a first disc. A second opening flange is threadedly connected to the first opening flange and located inside the first opening flange, and has a second disc opposite to the first disc; and a spacer located on the inner side of the lid body. When the first and second opening flanges are connected, the first and second discs press the spacer tightly against the inner side of the lid body. This invention adds a spacer to the inner side of the lid body of the open-top can, separating the contents of the can from the lid body, preventing direct contact and thus preventing reactions.
[0003] However, this open-top container lacks structural reinforcement, allowing the liquid inside to exert internal pressure. Conventional oil drums generally have poor structural strength, and the lid seal is also ineffective. Therefore, it is necessary to improve this structure to overcome these shortcomings.

[0017] A sealing barrel lid is provided with a fixing part. The shape of the inner side of the fixing part of the sealing barrel lid is adapted to the elastic sealing ring, so that the sealing barrel lid can seal the carrying barrel body.
[0018] The present invention is further configured such that the fastening component includes:
[0019] A fixing clamp is fitted onto the fixing part and the bending part of the sealing barrel lid. The fixing clamp is provided with a connecting hole, and the elastic sealing ring and the sealing barrel lid are fixed to the bearing barrel body by the fixing clamp.
[0020] A fixing bolt is provided in the connection hole of the fixing clamp;
[0021] A fastening nut, which is compatible with a fixing bolt, is used to secure the clamp by cooperating with the fixing bolt.
[0022] The present invention is further configured such that the lifting component includes:

[0025] The present invention is further configured such that the load-bearing strengthening component includes:
[0026] The large reinforcing ribs are provided in pairs and are formed in the middle of the bearing tank. The large reinforcing ribs are triangular in shape, protrude outwards from the bearing tank and extend circumferentially, thereby increasing the bending deformation resistance of the middle part of the bearing tank.
[0027] The present invention is further configured such that the load-bearing strengthening component includes:
[0028] Large reinforcing ribs, a pair of which are formed in the middle of the bearing barrel, are triangular in shape and protrude outward toward the outside of the bearing barrel. The large reinforcing ribs increase the bending deformation resistance of the middle of the bearing barrel.
[0029] Small reinforcing ribs are provided in two sets. The small reinforcing ribs are triangular in shape and are symmetrically formed on the upper and lower sides of the supporting barrel, thereby increasing the structural strength of the supporting oil barrel.

Detailed Implementation
[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0046] like Figure 1-3 As shown, the present invention proposes a straight-mouthed open bucket with a reinforced structure, which further includes a support member, a sealing member, a fastening member, a lifting member, and a load-bearing reinforcement member. The support member is cylindrical in shape and has a storage space. The sealing member is located at the top of the support member and seals the top of the support member. The fastening member is located at the top of the support member and contacts the sealing member to fix the sealing member and the support member. The lifting member is formed at the bottom of the support member and supports the bottom of the support member. Stacking the support members can ensure the stability of the stacked buckets. The load-bearing reinforcement member is formed in the support member and increases the load-bearing capacity of the support member.
[0047] In this embodiment, the support member includes a support barrel 110 and a bending portion 120. The support barrel is cylindrical in shape and has an opening at the top. The bending portion is formed at the top of the support barrel and extends outward toward the outside of the support barrel. The bending portion is arc-shaped and increases the bending resistance of the top of the support barrel.
[0048] In this embodiment, the sealing component includes an elastic sealing ring 210 and a sealing lid 220. The elastic sealing ring is disposed at the top of the bent portion, and its shape is adapted to the bent portion. Adhesive portions 211 are provided on both sides of the elastic sealing ring, extending towards the bottom of the elastic sealing ring. The elastic sealing ring ensures the sealing of the carrying barrel. The sealing lid has a fixing portion, the inner shape of which is adapted to the elastic sealing ring. The sealing lid seals the carrying barrel. When the sealing lid is fixed, it presses the elastic sealing ring downwards. When the elastic sealing ring is subjected to force, the adhesive portion deforms and extends downwards, thereby increasing the contact area between the adhesive portion, the bent portion, and the carrying barrel, effectively increasing the sealing effect. Simultaneously, the adhesive portion, adapted to the shape of the bent portion and the carrying barrel, can limit the sealing ring's position slightly to the left or right, preventing displacement of the sealing ring.
[0049] In this embodiment, the fastening components include a fixing clamp 310, a fixing bolt 320, and a fastening nut 330. The fixing clamp is sleeved on the fixing part and the bent part of the sealing barrel lid. The fixing clamp is provided with a connecting hole, which fixes the elastic sealing ring and the sealing barrel lid to the bearing barrel body. The fixing bolt is set in the connecting hole of the fixing clamp, and the fastening nut is adapted to the fixing bolt. The fastening nut and the fixing bolt cooperate to fix the fixing clamp. It is worth noting that the fixing clamp is made of a metal material with a certain degree of elasticity, which can meet the needs of fixing the sealing barrel lid. The structure and material of the fixing clamp are existing technologies and will not be described in detail here.
[0050] In this embodiment, the lifting component includes a support base 410, which is disposed at the bottom of the oil drum and protrudes toward the bottom of the oil drum.
[0051] In one embodiment of this utility model, a buffer pad 411 is provided at the bottom of the support base to absorb the impact force and prevent the bottom of the oil drum from deforming when the oil drum falls from a height during movement.
[0052] In this embodiment, an anti-bending portion 510 is formed on the inner side of the bend. The anti-bending portion is in the shape of an inwardly curled circle. The anti-bending portion increases the structural strength of the bend. Conventional bends only have one ring and do not have an anti-bending portion. When the bend is impacted, the bend deforms, which can cause the sealing ring to loosen and the stored liquid to leak out. However, in this embodiment, by setting an anti-bending portion in the bend, the anti-bending portion can disperse the impact force when the bend is impacted. At the same time, the circular anti-bending portion can effectively increase the impact resistance.
[0053] In this embodiment, the load-bearing reinforcement component includes a large reinforcing rib 610. There are two pairs of large reinforcing ribs. The large reinforcing ribs are formed in the middle of the load-bearing barrel. The shape of the large reinforcing ribs is triangular. The large reinforcing ribs protrude towards the outside of the load-bearing barrel and extend in the circumferential direction. The large reinforcing ribs increase the bending deformation resistance of the middle of the load-bearing barrel.
[0054] Example 2
[0055] like Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the load-bearing reinforcing component includes a large reinforcing rib 610 and a small reinforcing rib 620. A pair of large reinforcing ribs are provided, formed in the middle of the load-bearing barrel. The large reinforcing ribs are triangular in shape and protrude outwards from the load-bearing barrel, increasing the bending deformation resistance of the middle of the load-bearing barrel. Two sets of small reinforcing ribs are provided, also triangular in shape, symmetrically formed on the upper and lower sides of the load-bearing barrel, increasing the structural strength of the load-bearing barrel. In this embodiment, multiple small reinforcing ribs replace the upper and lower large reinforcing ribs. Because the middle of the barrel bears a larger internal liquid pressure, while the pressure at the top and bottom is relatively smaller, the upper and lower large reinforcing ribs are structurally redundant. By setting small reinforcing ribs, structural redundancy is reduced while ensuring the overall strength of the barrel. Furthermore, because the number of large reinforcing ribs is small, the internal liquid pressure on a single rib is large, making it prone to cracking and deformation after repeated pressure, reducing its service life. Multiple small reinforcing ribs can effectively disperse the pressure, thereby effectively improving the service life of the barrel.
[0056] Comparative test: In tests on oil drums with different reinforcing rib structures, for oil drums of the same material, the lifespan of the drum with differentiated reinforcing rib design is about 20% longer than that of the drum with uniform rib design.
[0057] Example 3
[0058] like Figure 6-7 As shown, the difference between this embodiment and Embodiment 2 is that, in this embodiment, the load-bearing reinforcing member further includes a pair of vertical reinforcing ribs 630. These vertical reinforcing ribs are located inside the load-bearing barrel and are triangular in shape. The vertical reinforcing ribs increase the load-bearing barrel's resistance to bending deformation. When transporting oil drums, they need to be stacked, resulting in significant vertical pressure. The vertical reinforcing ribs can effectively improve the oil drum's resistance to bending. Furthermore, triangular reinforcing ribs have better bending resistance than arc-shaped reinforcing ribs, effectively improving the structural strength of the oil drum and adapting it to different usage scenarios. The vertical reinforcing ribs can be fixed by welding.
[0059] In this embodiment, a corrosion-resistant coating 111 (not shown in the figure) is provided on the inner side of the bearing tank. The corrosion-resistant coating is an aluminum-plated coating. By providing the corrosion-resistant coating, the corrosion resistance of the inner side of the oil tank is increased, thereby increasing the service life of the oil tank.
[0060] In this embodiment, the bottom of the bearing tank is provided with a supporting protrusion 640. By providing the supporting protrusion, the bottom of the bearing tank is supported, preventing it from being suspended due to the lack of a supporting structure at the center of the bearing tank, which would increase the pressure in the central area of the bearing tank and cause it to deform. This effectively increases the structural strength and service life of the oil drum.
[0061] The working principle of this utility model:
[0062] The sealing ring and sealing cap are placed on the bent part of the carrying tank, and the fixing clamp is fastened to the outside of the sealing cap at the bent part. When the fixing clamp is tightened, it compresses the elastic sealing ring, and the contact part of the elastic sealing ring extends downward under force, closely adhering to the bent part and the sealing cap. As the contact part extends, it increases the contact area with the bent part and the sealing cap, thereby improving the sealing effect. At the same time, the fixing clamp is fixed by the fixing bolts and fastening nuts. When transporting liquid, the large reinforcing rib and the small reinforcing rib work together to strengthen the structure of the carrying tank. Meanwhile, the supporting base prevents the carrying tank from directly contacting the ground, avoiding damage to the bottom of the carrying tank and increasing the service life of the oil drum.
