Description

Technical Field

[0001] This utility model belongs to the field of plastic products technology, and specifically relates to a barrel lid structure with high sealing performance. Background Technology

[0002] Plastic products refer to a general term for daily necessities and industrial products made primarily from plastics. This includes products manufactured using all processes such as injection molding and thermoforming. Plastics are a type of plastic synthetic polymer material with natural or synthetic resins as the main components and various additives added. Under certain temperature and pressure conditions, they can be molded into a certain shape and maintain their shape at room temperature. This includes various bucket products made from plastics.

[0003] A review of announcement number CN208278612U reveals a highly leak-proof bottled water cap structure. This technology discloses "a bottle opening and a cap body, wherein the cap body has an outer ring wall that is threadedly adapted to the outer wall of the bottle opening and an inner ring wall that is threadedly adapted to the inner wall of the bottle opening; an annular protrusion is provided on the outer wall of the bottle opening, and the thread on the outer wall of the bottle opening is disposed on the annular protrusion; an annular groove is provided on the outer wall of the bottle opening at a position between the annular protrusion and the end of the bottle opening; an annular elastic sealing ring is installed on the annular groove; the outer wall of the annular elastic sealing ring is a slope extending outward and downward, and the inner surface of the outer ring wall has a corresponding slope that is mutually adapted; when the bottle opening and the cap body are threadedly locked, the slope and the slope are in an interference fit state. This utility model provides a highly leak-proof bottled water cap structure, and the fit between the cap and the bottle opening produces a better sealing effect, ensuring a better leak-proof performance."

[0004] Although the design can produce a better sealing effect between the lid and the opening of the bucket and ensure that there is no leakage, during daily use, the lid and the bucket body may rotate in reverse under the influence of external forces, which will affect the seal between them and cause the contents to leak.

[0005] To address the aforementioned issues, this application proposes a barrel lid structure with high sealing performance. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a highly airtight bucket lid structure. Through the interaction of the slot and the locking block, the lid body and the bucket body can only rotate in one direction, thus forming a tight connection and preventing reverse rotation due to external forces. When it is necessary to open the lid body and the bucket body, the locking block and the slot can be separated by pressing down on the pressure plate, allowing the bucket body and the locking block to be easily removed, thus facilitating the storage and retrieval of items inside the bucket.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing bucket lid structure, comprising a bucket lid body and a bucket body, wherein the bucket lid body and the bucket body are threadedly connected, a slot is provided on one side of the bucket lid body, a bucket neck is provided on the surface of the bucket body, a spring is installed on the inner surface of the bucket neck, one end of the spring is fixedly connected to the surface of the locking block, and the other end of the locking block is connected to the inside of the sliding groove, wherein the sliding groove is provided on the surface of the bucket neck.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] like Figure 1 As shown:

[0023] A high-sealing bucket lid structure includes a bucket lid body 1.

[0024] In this implementation plan: The existing announcement number: CN208278612U discloses a high-sealing barrel lid structure for bottled water. The technical means of this invention will not be described in detail here. For improvements to this prior art, please refer to the following disclosure. To solve the technical problems existing in this prior art, such as the "in the daily use of the device, the lid body 1 and the barrel body 4 may rotate in reverse under the influence of external force, which will affect the sealing between the two and cause leakage of the contents" in the context of use, this problem is obviously real and difficult to solve. Therefore, to solve the above problem, a lid edge 2 and a slot 3 are added on the basis.

[0025] Furthermore:

[0026] like Figure 1 - Figure 4 As shown:

[0027] Based on the above: the lid body 1 and the body 4 are threaded together. A groove 3 is provided on one side of the lid body 1. A neck 5 is provided on the surface of the body 4. A spring 10 is installed on the inner surface of the neck 5. One end of the spring 10 is fixedly connected to the surface of the locking block 11. The other end of the locking block 11 is connected to the inside of the slide groove 9. The slide groove 9 is provided on the surface of the neck 5.

[0028] In this implementation scheme: the action between the slot 3 and the block 11 enables the lid body 1 and the body 4 to rotate in only one direction, which can effectively prevent the lid body 1 and the body 4 from rotating in the opposite direction, and keep the lid body 1 and the body 4 connected at all times. The lifting spring 6 and the pressure plate 7 can drive the block 11 and the slot 3 to separate when the lid body 1 needs to be opened, so that the lid body 1 can be opened when needed.

[0029] Furthermore:

[0030] In an optional embodiment, the lid body 1 and the lid edge 2 form an integrated structure, and the slot 3 is formed at an equal angle on the surface of the lid edge 2.

[0031] In this embodiment, the slots 3 set at equal angles on the surface of the lid body 1 can connect with the block 11 when the lid body 1 and the barrel body 4 rotate, thereby preventing the lid body 1 and the barrel body 4 from rotating in the opposite direction through the engagement between the slots 3 and the block 11.

[0032] Furthermore:

[0033] In an optional embodiment, a lifting spring 6 is also installed on the surface of the barrel body 4, and one side of the lifting spring 6 is fixedly connected to the surface of the pressure plate 7. The pressure plate 7 is sleeved on the surface of the barrel body 4, and one side of the pressure plate 7 is fixedly connected to one end of the connecting rod 8. The surface of the connecting rod 8 extends to the inner surface of the barrel neck 5 and is fixedly connected to one side of the locking block 11.

[0034] In this embodiment, the lifting spring 6 and pressure plate 7 installed on the surface of the barrel body 4 can prevent the locking block 11 from sinking under the action of the pressure plate 7, thereby preventing the locking block 11 from separating from the locking groove 3, and effectively preventing the barrel lid body 1 and the barrel body 4 from rotating in opposite directions, which would cause the connection between the two to be loose.

[0035] Furthermore:

[0036] In an optional embodiment, a spring 10 is also sleeved on the surface of the connecting rod 8, and the two ends of the spring 10 are fixedly connected to the surfaces of the locking block 11 and the slide groove 9, respectively.

[0037] In this embodiment, the spring 10 sleeved on the surface of the connecting rod 8 can accumulate elastic force when the locking block 11 moves, thereby enabling the connection between the locking block 11 and the locking slot 3.

[0038] Furthermore:

[0039] In an optional embodiment, the groove 9 is formed at an equal angle on the surface of the neck 5, and the shape of the groove 9 matches that of the locking block 11.

[0040] In this embodiment, the equally angled grooves 9 allow the locking block 11 to slide inside the grooves 9 when the lid body 1 rotates, thereby stably achieving the retraction function of the locking block 11.

[0041] Furthermore:

[0042] In an optional embodiment, the shape of the card block 11 is composed of a cuboid and a right-angled trapezoidal prism, and the top shape of the card block 11 matches the shape of the card slot 3.

[0043] In this embodiment, the right-angled trapezoidal column structure at the end of the locking block 11 enables the lid body 1 to slide through the locking groove 3 and the inclined surface of the top surface of the locking block 11 when it rotates, thereby allowing the lid body 1 and the bucket body 4 to rotate smoothly.

[0044] The working principle and usage process of this utility model are as follows: When it is necessary to connect the lid body 1 and the barrel body 4, the lid body 1 and the lid edge 2 can be gradually rotated onto the barrel body 4. At this time, the lid edge 2 will drive the slot 3 to gradually move to the position of the locking block 11. Subsequently, the slot 3 and the lid edge 2 will gradually slide with the locking block 11. The locking block 11 will slide in the sliding groove 9 set on the inner surface of the barrel neck 5. At the same time, the locking block 11 will repeatedly compress the spring 10. The bottom of the locking block 11 will also drive the connecting rod 8 and the pressure plate 7 to move up and down. When a tight connection is formed between the lid body 1 and the barrel body 4... After that, the locking block 11 will form a tight connection with the locking groove 3. At this time, it will be difficult for the locking block 11 and the locking groove 3 to move in the opposite direction, and it will also be difficult for the lid body 1 and the barrel body 4 to rotate in the opposite direction again. This ensures the tightness of the connection between the two and prevents them from becoming loose or separating. When it is necessary to open the lid body 1, the pressure plate 7 can be pressed down. At this time, each connecting rod 8 will drive the locking block 11 and the sliding groove 9 to slide and retract into the interior of the sliding groove 9. At this time, the locking groove 3 and the lid body 1 are no longer blocked by the locking block 11, and the lid body 1 can be removed from the barrel body 4.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
