Description

Technical Field

[0001] This utility model relates to the field of plastic bucket technology, and more specifically, to a plastic bucket with a constricted top opening. Background Technology

[0002] The top-neck plastic drum is a special type of oil drum with a top-neck design. The top-neck design is usually used in conjunction with a sealing cap to improve the sealing performance of the oil drum, prevent oil leakage, and maintain the quality and stability of the oil, preventing external factors from contaminating or affecting it.

[0003] Existing top-neck plastic drums experience wear and tear on the sealing cap after prolonged use, leading to a decrease in sealing performance. If the drum tilts and is not detected in time, continuous leakage of oil may occur from the opening. Therefore, a new solution is needed to address the problem of continuous oil leakage when the drum tilts due to the deterioration of the sealing performance after prolonged use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a top-narrowing plastic bucket with a sealing block installed at the opening of the bucket body to seal off the oil leak and reduce the probability of continuous oil leakage.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a top-narrowed plastic bucket, including a bucket body and a bucket lid, wherein the bucket lid is detachably connected to the bucket body, a receiving cavity is formed on the inner top surface of the bucket lid, a sealing component is slidably connected to the inner wall of the receiving cavity, a sliding groove communicating with the receiving cavity is formed in the bucket lid, the sliding groove is L-shaped, a driving component is slidably connected in the sliding groove, the driving component extends out of the sliding groove and its upper surface abuts against the sealing component, a through groove communicating with the sliding groove is formed on the inner side wall of the bucket lid, when the weight of the driving component increases and it slides to the lowest position, the sealing component slides on the inner wall of the receiving cavity and passes through the receiving cavity and extends into the opening of the bucket body.

[0006] The present invention is further configured such that: the driving component includes an oil-absorbing component and a blocking plate slidably connected to the inner wall of the sliding groove; the blocking plate is fixedly connected to the oil-absorbing component by a traction rope; the upper surface of the blocking plate abuts against the sealing component; and the distance between the oil-absorbing component and the ground is less than the distance between the bottom surface of the through groove and the through groove.

[0007] The present invention is further configured such that: the sealing component includes a sealing block and several elastic elements, the cross-sectional area of ​​the sealing block near the blocking plate is the same as the cross-sectional area of ​​the opening of the barrel, the lower surface of the sealing block abuts against the blocking plate, one end of the elastic element is fixedly connected to the upper surface of the sealing block, and the other end of the elastic element is fixedly connected to the top surface of the receiving cavity.

[0008] The present invention is further configured such that: the cross-sectional area of ​​the sealing block on the side near the elastic element is smaller than the cross-sectional area on the other side, and an expansion ring is fixedly connected to the outer peripheral wall of the sealing block on the side near the elastic element.

[0009] The present invention is further configured such that the distance between the oil-absorbing component and the lower surface of the sliding groove is greater than the length of the blocking plate extending out of the sliding groove.

[0010] The present invention is further configured such that the distance between the through groove and the lower surface of the bucket lid is less than the distance between the through groove and the upper surface of the bucket lid.

In the initial state, the sealing block is contained in the receiving cavity by the pressure of the blocking plate. When oil leaks, the oil will come into contact with the oil suction component in the sliding groove. The increased weight of the oil suction component will cause it to move and drive the blocking plate to move, causing the pressure on the sealing block to disappear. The sealing block is pushed out of the receiving cavity by the elastic component and enters the opening of the bucket body to seal the bucket body, reducing the probability of oil continuously leaking out of the bucket body.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A type of plastic bucket with a tapered top, such as Figures 1-2 As shown, the device includes a barrel body 1 and a barrel lid 2. The barrel lid 2 is detachably connected to the barrel body 1 and is a threaded lid. The tight engagement of the threads forms an effective seal, effectively preventing oil leakage from the barrel body 1. A receiving cavity 3 is formed on the top inner surface of the barrel lid 2. A sealing component is slidably connected to the inner wall of the receiving cavity 3. A sliding groove 4 communicating with the receiving cavity 3 is formed inside the barrel lid 2. The sliding groove 4 is L-shaped, and a driving component is slidably connected inside the sliding groove 4. The driving component extends out of the sliding groove 4, and its upper surface abuts against the sealing component. In the initial state, the driving component houses the sealing component within the receiving cavity 3. A through groove 5 communicating with the sliding groove 4 is formed on the inner side wall of the barrel lid 2. The spiral patterns on the lid 2 are misaligned with those on the inner wall of the lid 2 to avoid affecting the original sealing effect of the lid 2 on the barrel 1. After long-term use, wear occurs at the opening between the lid 2 and the barrel 1. When the barrel 1 tilts and oil flows out, the oil comes into contact with the drive component in the sliding groove 4 through the through groove 5, causing the drive component to slide in the sliding groove 4. When the length of the drive component extending out of the sliding groove 4 is zero, the sealing component slides on the inner wall of the receiving cavity 3 and extends out of the receiving cavity 3 into the opening of the barrel 1 to seal the opening of the barrel 1. When the oil in the barrel 1 leaks, the sealing component seals the opening of the barrel 1, reducing the probability of a large amount of oil leakage.

[0019] like Figures 1-3 As shown, the driving assembly includes an oil-absorbing element 6 and a blocking plate 7 slidably connected to the inner wall of the sliding groove 4. The blocking plate 7 is bonded to the oil-absorbing element 6 via a traction rope 8. The blocking plate 7 is located at one end of the sliding groove 4 near the receiving cavity 3 and extends out of the sliding groove 4 to abut against the sealing assembly, so that the sealing assembly in the initial state is contained within the receiving cavity 3 by the blocking plate 7, preventing the sealing assembly from extending out of the receiving cavity 3 under normal conditions and thus causing wear. The distance between the oil-absorbing element 6 and the ground is less than the distance between the bottom surface of the through groove 5 and the ground. After the oil in the barrel 1 leaks, it comes into contact with the oil-absorbing element 6 in the sliding groove 4 through the through groove 5. The material of the oil-absorbing element 6 is activated carbon, and activated carbon has... With its highly developed porous structure and non-polar surface, activated carbon can effectively capture oil molecules through physical adsorption. However, the activated carbon itself does not undergo a significant volume change due to the absorption of oil, thus avoiding the problem of its inability to slide within the sliding groove 4 due to increased volume from absorbing oil. The oil-absorbing component 6 absorbs oil, and its own weight increases, causing it to move downwards. The traction rope 8 causes the blocking plate 7 to move on the inner wall of the sliding groove 4. After the blocking plate 7 completely enters the sliding groove 4, the resistance encountered by the sealing component disappears, and it passes through the receiving cavity 3 and enters the opening of the barrel 1 to seal the opening of the barrel 1, preventing further leakage of oil.

[0020] like Figures 1-3As shown, the sealing assembly includes a sealing block 9 and four elastic elements 10. The elastic elements 10 are springs. The cross-sectional area of ​​the sealing block 9 near the blocking plate 7 is the same as the cross-sectional area of ​​the opening of the barrel 1. When the sealing block 9 passes through the receiving cavity 3, it can completely seal the opening of the barrel 1, and at the same time, it prevents oil from entering the interior of the receiving cavity 3 under normal use. One end of the elastic element 10 is bonded to the upper surface of the sealing block 9, and the other end of the elastic element 10 is bonded to the top surface of the receiving cavity 3. In the initial state, the lower surface of the sealing block 9 abuts against the blocking plate 7, and the sealing block 9 exerts pressure on the elastic element 10, causing the elastic element 10 to be in a fully compressed state. When the blocking plate 7 completely enters the sliding groove 4, the pressure on the elastic element 10 disappears and rebounds, generating a thrust on the sealing block 9, causing the sealing block 9 to slide out of the receiving cavity 3 and enter the opening of the barrel 1 to seal, reducing the probability of oil leakage.

[0021] like Figures 1-3 As shown, the cross-sectional area of ​​the sealing block 9 on the side near the elastic element 10 is smaller than that on the other side. An expansion ring 11 is bonded to the outer peripheral wall of the sealing block 9 on the side near the elastic element 10. The material of the sealing block 9 is polytetrafluoroethylene (PTFE). PTFE has good oil resistance and will not react with oil. The material of the expansion ring 11 is oil-swellable rubber. The expansion ring 11 is set on the side of the sealing block 9 away from the barrel 1. When some oil flows out from the side of the sealing block 9 into the opening of the barrel 1, it will be absorbed by the expansion ring 11, causing the expansion ring 11 to increase in volume and press against the inner wall of the barrel cover 2, thereby further reducing the probability of continued oil leakage.

[0022] like Figures 1-3 As shown, the distance between the oil suction component 6 and the lower surface of the sliding groove 4 is greater than the length of the blocking plate 7 extending out of the sliding groove 4. This ensures that the blocking plate 7 can be completely pulled into the sliding groove 4 during the downward movement of the oil suction component 6, so that the pressure on the sealing block 9 disappears and can pass through the receiving cavity 3 to enter the opening of the barrel 1 to seal the barrel 1. The through groove 5 is set near the lower surface of the barrel cover 2, which reduces the probability that the sealing block 9 will pass through when the oil slightly overflows.

[0023] Working principle: A top-neck plastic bucket, when oil leaks from the lid 2, it comes into contact with the oil-absorbing component 6 through the groove 5. After absorbing the leaked oil, the oil-absorbing component 6 increases in weight and moves downward. The movement is transmitted to the blocking plate 7 through the traction rope 8. The blocking plate 7 moves in the sliding groove 4 and is completely retracted into the sliding groove 4. The pressure on the sealing block 9 disappears, and the elastic component 10 rebounds, generating a pushing force on the sealing block 9, causing the sealing block 9 to pass through the receiving cavity 3 and enter the opening of the bucket body 1 to seal the bucket body 1 and prevent continuous oil leakage. If oil passes through the side of the sealing block 9, it will come into contact with the expansion ring 11, causing the expansion ring 11 to expand and further seal the bucket body 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
