Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding wire storage devices, specifically to a ten-cornered bucket. Background Technology
[0002] After production, welding wire is typically coiled and wound inside a welding wire cassette for easy handling, storage, and transportation. Existing welding wire cassettes are usually made by bonding multiple layers of kraft paper together to form a cardboard of a certain thickness, then rolling it into a cylindrical shape. To ensure the cassette's load-bearing capacity, wooden or iron plates are used to support the lid and bottom. Iron hoops are then used to secure the lid and bottom to the upper and lower sides of the cassette, forming a cylindrical shape. Rivets are used to fix the handle to the cassette. This requires each part of the welding wire cassette's structure and connections to have sufficient strength to support the transport of a full cassette of welding wire, making the manufacturing process cumbersome and complex. Furthermore, welding wire cassettes are relatively large and cannot be compressed or stacked; they can only be transported by stacking, making transportation very difficult. Additionally, existing welding wire cassettes use multiple materials such as cardboard, wooden boards, and iron hoops, and disassembly is difficult, hindering the recycling and reuse of the welding wire cassette materials. Utility Model Content
[0003] The purpose of this utility model is to provide a decagonal bucket that can be folded and stored during transportation, and whose overall structure is simple, making it easy to disassemble and recycle.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A decagonal bucket includes a bucket body with a lid detachably connected to the upper part of the bucket body. The bucket body includes a side wall and a bottom. The side wall has a regular decagonal cross-section and is formed by bending a rectangular plate. The lower side of the rectangular plate is bent towards the bottom of the bucket to form a connecting part, which overlaps with and connects to the bottom of the bucket. The bucket also includes a sling that passes through the lower side of the bottom of the bucket and forms a hanging loop at both ends. The hanging loop protrudes from the outside of the side wall.
[0006] Preferably, the barrel body and the barrel lid are both made of cardboard; the cross-section of the barrel lid and the barrel bottom is conformal to the cross-section of the side wall.
[0007] Preferably, the sidewall includes an inner sidewall and an outer sidewall sleeved on the outside of the inner sidewall; the connecting part includes a first connecting part and a second connecting part, the first connecting part is disposed on the lower side of the outer sidewall and the second connecting part is disposed on the lower side of the inner sidewall, and the bottom of the bucket is disposed between the first connecting part and the second connecting part.
[0008] Preferably, the connecting part is a plurality of trapezoidal plates, each trapezoidal plate corresponding to the side edge of the sidewall; when the connecting part is connected to the bottom of the bucket, the side edges of adjacent trapezoidal plates fit together.
[0009] Preferably, it also includes a moisture-proof bag, which is disposed between the inner and outer side walls, and the bottom of the moisture-proof bag is disposed between the bottom of the bucket and the lifting strap.
[0010] Preferably, it also includes a barrel core, and a boss that mates with the barrel core is provided in the middle of the inner side of the barrel bottom. The barrel core is sleeved and fixed on the boss, and the barrel core is cylindrical.
[0011] Preferably, elongated holes for inserting pressure rods are provided on both sides of the barrel core, and a folding plate is provided on the upper surface of the boss. The folding plate can be bent upwards to stand upright. A fixing hole is provided on the folding plate, and a spring is connected in the fixing hole. The other end of the spring is connected to the pressure rod.
[0012] Preferably, the lid is formed by folding and assembling cardboard.
[0013] Preferably, the edge of the bucket lid has a downwardly extending rim, and the inner side of the rim is tightly joined to the outer side of the outer wall.
[0014] Preferably, the bottom of the barrel and the boss are both formed by overlapping and bonding multiple layers of cardboard.
[0015] Compared with the prior art, the above technical solution has the following beneficial effects:
[0016] 1. Compared with the existing technology that uses cardboard, wood, iron hoops and rivets to connect the welding wire canister to ensure the load-bearing strength of the welding wire canister, this utility model uses a lifting strap that passes through the bottom of the canister and exits through the side wall to form a decagonal canister as a whole. In this way, when the welding wire canister is moved, the lifting strap bears most of the load of the canister. Furthermore, the use of cardboard as the side wall and bottom of the canister in this utility model allows the canister to still store and transport welding wire.
[0017] 2. Compared to the existing technology where a circular welding wire hopper is assembled and then sent to the welding wire factory, this invention uses cardboard for the side walls and bottom. The cardboard is foldable and easy to assemble, significantly reducing the size of the welding wire hopper and improving transportation efficiency. Furthermore, using cardboard to make the welding wire hopper facilitates its recycling and reuse. Attached Figure Description

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings:
[0027] like Figures 1 to 7 As shown, a decagonal bucket includes a bucket body 1, with a lid 2 detachably connected to the upper part of the bucket body 1. Both the bucket body 1 and the lid 2 are made of cardboard, preferably corrugated cardboard with sufficient rigidity. The bucket body 1 includes side walls 3 and a bottom 4. The side walls 3 are formed by bending rectangular plates 7. The lower side of the rectangular plates 7 is bent towards the bottom 4 to form a connecting part 5, which overlaps and connects with the bottom 4. During transportation, the bucket body 1 can be disassembled into the side walls 3 and the bottom 4, and the bucket walls 3 can be further folded into square plates, which greatly reduces the space occupied by the bucket body 1, making it easy to fold and transport. It also includes a lifting strap 6, preferably made of nylon rope. The lifting strap 6 passes through the lower side of the bottom 4, and the two ends of the lifting strap 6 form lifting rings 61. The lifting rings 61 protrude from the outside of the side walls 3, facilitating the movement of the bucket body. At the same time, the lifting strap 6 strengthens the bottom 4, preventing the bottom 4 from being crushed and causing the welding wire to fall from the bottom.
[0028] The cross-section of the sidewall is a regular polygon, preferably a regular decagon. The cross-sections of the lid 2 and the bottom 4 of the bucket follow the shape of the sidewall 3. Multiple longitudinal first bending lines 12 are evenly spaced on the rectangular plate 7. The rectangular plate 7 is bent along the first bending lines 12, and the ends of the rectangular plate 7 are joined together to form a regular polygonal sidewall 3. A transverse second bending line 13 is provided on the lower side of the rectangular plate. The lower side of the rectangular plate 7 is bent towards the bottom 4 along the second bending line 13 to form a connecting part 5. The connecting part 5 is cut and divided into multiple square plates along the first bending lines 12. The edges of the square plates are cut to form isosceles trapezoidal plates 53. Each trapezoidal plate 53 corresponds one-to-one with the side edge of the sidewall 3. When the connecting part 5 is connected to the bottom 4 of the bucket, the sides of adjacent trapezoidal plates 53 are close together or adjacent to each other to avoid overlapping trapezoidal blocks 53, which would cause unevenness at the bottom of the bucket. In this embodiment, the first and last edges of the rectangular plate 7 are fixed together with packing nails, and the connecting part 5 and the bottom of the barrel 4 are fastened together with packing nails. Each trapezoidal plate 53 is connected to the barrel body 4 with packing nails.
[0029] In one embodiment, the sidewall 3 includes an inner sidewall 31 and an outer sidewall 32 fitted outside the inner sidewall 31. Preferably, the outer sidewall 32 is larger than the inner sidewall 31, so that the outer sidewall 31 fits snugly outside the inner sidewall 31. The connecting part 5 includes a first connecting part 51 and a second connecting part 52. The first connecting part 51 is located on the lower side of the outer sidewall 32 and the second connecting part 52 is located on the lower side of the inner sidewall 31. The bottom of the bucket 4 is located between the first connecting part 51 and the second connecting part 52. The sling 6 is located between the inner sidewall 31 and the inner sidewall 31. Through holes 11 are provided on opposite sides of the outer sidewall, and the two ends of the sling 6 pass through the through holes 11.
[0030] In one embodiment, a moisture-proof bag 8 is also included. The moisture-proof bag 8 is disposed between the inner sidewall 31 and the outer sidewall 32, and the bottom of the moisture-proof bag 8 is disposed between the bottom of the bucket 4 and the lifting strap 6. In this way, the moisture-proof bag 8 can provide a relatively dry environment for the welding wire inside the bucket 1. At the same time, the inner sidewall 31 prevents the welding wire from tearing the moisture-proof bag 8, and the outer sidewall 32 prevents external objects from tearing the moisture-proof bag 8. In this embodiment, the perforation formed on the moisture-proof bag 8 when the sealing nail penetrates the bottom of the bucket and is fastened together does not affect the use of the welding wire during the turnover cycle.
[0031] In one embodiment, the device further includes a barrel core 9, with a boss 41 located in the middle of the inner side of the barrel bottom 4 to mate with the barrel core 9. The barrel core 9 is fitted and fixed onto the boss 41. Preferably, the barrel core 9 is cylindrical. The welding wire is wound and coiled around the barrel core 9 inside the barrel body 1 to prevent the welding wire from loosening. Preferably, both the barrel bottom 4 and the boss 41 are formed by overlapping and bonding multiple layers of cardboard.
[0032] The barrel core 9 has elongated holes 91 on both sides for inserting pressure rods. A folding plate 42 is provided on the upper surface of the boss 41. The folding plate 42 can be bent upwards to an upright position. A fixing hole 43 is provided on the folding plate 42, and a spring (not shown in the attached drawing) is connected inside the fixing hole 43. The other end of the spring is connected to the pressure rod. After the welding wire is wound and coiled, both ends of the pressure rod (not shown in the attached drawing) pass through the elongated holes 42 and press against the top of the welding wire. At this time, the spring is in a stretched state. As the spring recovers its deformation, it pulls the pressure rod downwards, thus making the pressure rod firmly press against the welding wire to prevent it from loosening. In this embodiment, the strength of the elongated holes 42 and the fixing holes 43 is sufficient to fix the spring and the pressure rod, or a reinforcing part is provided around the elongated holes 42 and the fixing holes 43. Furthermore, the pressure rod can be a telescopic rod, which facilitates its installation and insertion from inside the barrel core 9.
[0033] In one embodiment, the lid 2 is formed by folding and assembling cardboard, and the edge of the lid 2 is provided with a downwardly extending rim 21, the inner side of which is tightly joined to the outer side of the outer wall 32.
[0034] In the above technical solution, a rectangular plate 7 is used to enclose and form an inner wall 31 and an outer wall 32. After the two ends of the sling 6 are passed through the opening 11, the inner wall 31 and the bottom of the bucket 4 are installed inside the moisture-proof bag 8. Then, the outer wall 32 is fitted onto the outside of the moisture-proof bag 8, and then bent along the second fold line 13 to form a second connecting part 52 and a first connecting part 51. The bottom of the bucket 4 is then placed between the second connecting part 52 and the first connecting part 51, and the sling 6 is placed under the bottom of the bucket 4 and the moisture-proof bag 8. Then, the connecting part 5 and the bottom of the bucket 4 are fixed together with a sealing nail. Finally, the bucket core 9 is fitted onto the protrusion 41, so that the welding wire can be wound and coiled inside the bucket. After the welding wire is used, the sling 6 is pulled out, and the bucket is recycled and reused as a paper product.
[0035] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
