Description

Technical Field

[0001] This utility model relates to the technical field of containers and tanks, and in particular to a container and tank with good sealing performance. Background Technology

[0002] In the fields of food storage, pharmaceutical packaging, and fine chemicals, containers are the core equipment for holding and preserving contents over a long period. Their airtightness directly determines the quality stability, safety, and shelf life of the contents. For example, in the food industry, dried foods such as milk powder, nuts, and dehydrated vegetables have strict requirements for the humidity and oxygen content of the storage environment. If the container is not airtight, external moisture and oxygen can easily seep into the container, causing the food to absorb moisture, clump, oxidize, and spoil. This not only damages the taste but also shortens the shelf life. In the pharmaceutical industry, solid medicines such as capsules and tablets need to be isolated from microorganisms, dust, and external moisture. Failure to seal may cause drug contamination, deliquescence, and deterioration, affecting efficacy and even posing safety risks. In the fine chemical industry, the storage of some corrosive liquids or volatile reagents relies on the reliable sealing of containers. Once a leak occurs, it not only causes material loss but may also corrode equipment, endanger the health of operators, and cause safety accidents.

[0003] Currently, the mainstream sealing structures of containers and tanks on the market are mainly divided into three categories: threaded connection type, snap-fit ​​type, and simple compression type. In order to improve the sealing performance, some existing technologies have tried to add multiple sealing rings or complex sealing protrusions. However, the assembly of multiple sealing rings requires extremely high fitting precision, which not only increases the processing and assembly costs, but may also lead to a decrease in sealing performance due to inconsistent compression of each sealing ring. Complex sealing protrusion structures increase the difficulty of disassembling the top cover and the tank opening, making it inconvenient for ordinary users to operate. Moreover, the protrusions are prone to wear after long-term use, and the sealing reliability still cannot be guaranteed. Therefore, a container and tank with good sealing performance has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a container with good sealing performance to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A container with good sealing performance includes a container, the top of which is snapped onto a top cover, and the bottom edge of the top cover has a sealing ring.

[0007] An outer ring is fixedly connected to the edge of the top of the container. The top of the outer ring has multiple grooves, and a side block is engaged with the groove. A rotating ring is movably fitted on the top of the container. Multiple L-shaped side plates are fixedly connected to the side of the rotating ring. A clamping block is provided between the L-shaped side plate and the side block. A lifting and adjusting mechanism is provided on the top of the clamping block.

[0008] As a preferred embodiment of this utility model, one side of the side block is fixedly connected to the top cover, and the plurality of grooves are distributed in a ring array.

[0009] As a preferred embodiment of this utility model, the top of the container is provided with an annular groove.

[0010] In a preferred embodiment of this invention, the rotating ring is rotatably connected to the top of the container via an annular groove.

[0011] As a preferred embodiment of this utility model, a rubber pad is fixedly connected to the bottom end of the clamping block.

[0012] As a preferred embodiment of this utility model, the lifting adjustment mechanism includes a threaded rod rotatably connected to the top of the pressing block, the top of the threaded rod threaded through the surface of the L-shaped side plate on the same side and extending above it.

[0013] As a preferred embodiment of this utility model, a knob is fixedly connected to the top end of the threaded rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. The top cover achieves initial precise alignment with the container by using a single sealing ring on its edge in conjunction with the engagement of the side block and the outer ring groove. Simultaneously, a rotating ring, stably connected to the container via an annular groove, along with an L-shaped side plate fixed to the side of the rotating ring, a clamping block, and a lifting adjustment mechanism consisting of a threaded rod and a knob, allows the user to precisely control the pressure of the clamping block on the side block simply by rotating the knob. This ensures the sealing ring adheres evenly and tightly to the top of the container, effectively avoiding uneven compression of multiple sealing rings and guaranteeing stable and reliable sealing performance. Furthermore, this structure… The design eliminates complex sealing protrusions. Disassembly is simple: just rotate the knob in the opposite direction to loosen the clamping block, or rotate the rotating ring to detach the L-shaped side plate from the side block. The operation is quick and easy, perfectly suited to the needs of ordinary users, and completely eliminates the risk of protrusion wear, significantly improving the sealing reliability for long-term use. The rubber pad at the bottom of the clamping block prevents the clamping force from directly acting on the side block and causing wear, extending the service life of the components. The overall structural design takes into account sealing effect, ease of use, cost-effectiveness, and long-term durability, making it highly practical and widely applicable to various container and tank scenarios that require sealing performance.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions 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. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, a container with good sealing performance includes a container 1, which contains the contents to be stored and provides an installation base for components such as a top cover 2, an outer ring 3, and a rotating ring 6. The top of the container 1 is snapped with a top cover 2, and the bottom edge of the top cover 2 has a sealing ring 9. An annular groove 11 is provided on the top of the container 1.

[0027] An outer ring 3 is fixedly connected to the edge of the top of the container 1, providing a positioning and assembly structure. Multiple annular array grooves 4 on the top of the outer ring 3 can precisely engage with the side blocks 5 on the side of the top cover 2, restricting the rotation and offset of the top cover 2 in the horizontal direction. Multiple grooves 4 on the top of the outer ring 3 form an engaging and positioning structure with the side blocks 5. The side blocks 5 are engaged and connected at the grooves 4, transmitting pressure and assisting in positioning. One side of the side blocks 5 is fixedly connected to the top cover 2. The multiple grooves 4 are distributed in an annular array. A rotating ring 6 is movably fitted on the top of the container 1, driving the L-shaped side plate 7 to achieve position adjustment. It can rotate smoothly along the annular groove 11. When the top cover 2 needs to be installed, rotating the rotating ring 6 allows the L-shaped side plate 7 to align with the side blocks 5, providing pressure space for the clamping block 8. When the top cover 2 needs to be removed, rotating the rotating ring 6 in the opposite direction allows the L-shaped side plate 7 to disengage from the side blocks 5, eliminating the need for a complex disassembly structure and solving the problem of inconvenient disassembly caused by complex sealing protrusions in existing technologies. To meet the convenient operation needs of ordinary users, the rotating ring 6 is rotatably connected to the top of the container 1 through the annular groove 11. Multiple L-shaped side plates 7 are fixedly connected to the side of the rotating ring 6, serving as the mounting carrier for the lifting and adjusting mechanism 10. A clamping block 8 is provided between the L-shaped side plate 7 and the side block 5. The clamping block 8 can move up and down in the vertical direction by the lifting and lowering of the threaded rod 101. When pressed down, it can apply stable pressure to the side block 5, indirectly causing the sealing ring 9 of the top cover 2 to fit tightly against the top of the container 1. The clamping force can be controlled by adjusting the threaded rod 101 to avoid the sealing ring 9 from being damaged by overpressure or the sealing failure caused by insufficient pressure. Compared with the multi-seal rings of the prior art, this structure uses a single sealing ring in conjunction with the clamping block to apply pressure precisely, effectively solving the problem of uneven compression of multiple sealing rings and improving the stability of sealing performance. A rubber pad 12 is fixedly connected to the bottom of the clamping block 8 to buffer pressure and prevent wear. The lifting and adjusting mechanism 10 is provided on the top of the clamping block 8.

[0028] Preferably, the lifting adjustment mechanism 10 includes a threaded rod 101 rotatably connected to the top of the pressing block 8. The top thread of the threaded rod 101 passes through the surface of the L-shaped side plate 7 on the same side and extends above it. A knob 102 is fixedly connected to the top of the threaded rod 101, which is the core adjustment component for achieving precise pressure control.

[0029] In summary, first align the top cover 2 with the top opening of the container 1, so that the side block 5 fixed on the side of the top cover 2 precisely engages with the grooves 4 arranged in annular array on the outer ring 3 fixed at the top edge of the container 1. The engagement of the outer ring 3 and the side block 5 restricts the horizontal rotation and offset of the top cover 2, achieving initial positioning of the top cover 2. At the same time, the annular groove 11 on the top of the container 1 provides stable rotational support for the rotating ring 6. Then, rotate the rotating ring 6, which is connected to the container 1 through the annular groove 11, to drive the L-shaped side plate 7 fixed on its side to rotate above the side block 5. Then, rotate the knob 102 at the top of the threaded rod 101 in the lifting and adjusting mechanism 10, using the threaded rod... The threaded engagement between 101 and the L-shaped side plate 7 drives the threaded rod 101 to rotate the clamping block 8 at the bottom, causing it to descend vertically. This causes the rubber pad 12 at the bottom of the clamping block 8 to contact the side block 5 and apply pressure. The side block 5 then transmits the pressure to the top cover 2, causing the sealing ring 9 at the bottom of the top cover 2 to fit evenly and tightly against the top of the container 1 to achieve a seal. The clamping force can be adjusted by the knob 102 to prevent the sealing ring 9 from being damaged by overpressure or insufficient pressure. When disassembling, rotate the knob 102 in the opposite direction to raise the clamping block 8 to release the pressure, or rotate the rotating ring 6 to disengage the L-shaped side plate 7 from the side block 5. Then, lift the top cover 2 to disengage the side block 5 from the groove 4 to complete the disassembly.
