Description

Technical Field

[0001] This utility model relates to a sealing can buckle with automatic venting function, belonging to the technical field of sealing can buckles. Background Technology

[0002] A sealed container is a type of container used for storing goods and has excellent airtightness. It is typically made of materials such as glass, plastic, or metal. The latch on a sealed container is one of the core components that enables its sealing function. Its main function is to use mechanical force to tightly fasten the lid to the container body, thereby enhancing the seal and ensuring safe use.

[0003] When storing easily fermentable items, sealed containers need to have an automatic venting function. Current technology usually involves installing an venting valve on the sealed lid. However, the venting valve has a complex structure, often consisting of multiple detachable parts. Dirt can easily get trapped in the gaps, and cleaning requires disassembly one by one, which is inconvenient. Moreover, the venting valve is a consumable part that needs to be replaced frequently, resulting in high operating costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a sealing can buckle with automatic venting function, which does not require the use of an venting valve, is convenient to use, and has low operating cost.

[0005] The sealing can buckle with automatic venting function described in this utility model includes a can body connecting hoop, which is used to fit onto the can body of the sealing can. The rear part of the can body connecting hoop is hinged to the cover connecting hoop, and the front part of the can body connecting hoop is hinged to the snap fastener. The cover connecting hoop is used to fit onto the cover of the sealing can, and the rear part of the cover connecting hoop is provided with an venting spring. A pressure ring is hinged to the snap fastener, which is used to press down on the cover connecting hoop, thereby sealing the can body and the cover body together.

[0006] The technical solution of this utility model is to provide a sealing can buckle with an automatic venting function. When the pressure inside the sealing can is too high, the venting spring can be deformed to open the cover and release the pressure. After the pressure is released, the pressure inside the can is less than the elastic force of the venting spring, and the can and the cover return to a sealed state.

[0007] Preferably, the rear part of the tank connecting hoop has an open structure, and the two open ends of the tank connecting hoop are engaged with the connecting buckle. The tank connecting hoop can be separated from the tank by removing the connecting buckle.

[0008] Preferably, the front part of the cover connecting hoop is provided with a protruding connecting tongue, and the pressure ring cooperates with the connecting tongue to seal the tank body and the cover body.

[0009] Furthermore, the lower part of the snap fastener is provided with a pressure plate for easy pressing.

[0010] Furthermore, the tank body connecting hoop is hinged with a handle for easy lifting.

[0011] The advantages of this utility model compared with the prior art are:

[0012] The sealing can buckle with automatic venting function described in this utility model can cause the venting spring to deform when the pressure inside the sealing can is too high, thus opening the cover and releasing the pressure. After the pressure is released, the pressure inside the can is less than the elastic force of the venting spring, and the can and cover return to a sealed state. This utility model does not require the use of an venting valve, is convenient to use, and has low operating costs. Attached Figure Description

[0019] Example 1

[0020] like Figure 1-4 As shown, this embodiment is achieved through the following technical solution: it includes a tank body connecting hoop 3, which is used to be fitted onto the tank body of the sealed tank. The rear part of the tank body connecting hoop 3 is hinged to the cover connecting hoop 1, and the front part of the tank body connecting hoop 3 is hinged to the snap fastener 2. The cover connecting hoop 1 is used to be fitted onto the cover of the sealed tank. The rear part of the cover connecting hoop 1 is provided with an exhaust spring 12. A pressure ring 5 is hinged on the snap fastener 2. The pressure ring 5 is used to press down the cover connecting hoop 1, thereby sealing the tank body and the cover body together.

[0021] In this embodiment, the rear of the tank connecting clamp 3 is an open structure. The two open ends of the tank connecting clamp 3 are engaged with the connecting buckle 4. Removing the connecting buckle 4 allows the tank connecting clamp 3 to be separated from the tank. The front of the cover connecting clamp 1 has a protruding connecting tongue 11. The pressure ring 5 cooperates with the connecting tongue 11 to seal the tank and the cover. The lower part of the pressure buckle 2 has a pressure plate 21 for easy pressing.

[0022] The method of using this utility model is as follows:

[0023] When the pressure inside the sealed container is too high, the exhaust spring 12 will deform and push the cover open to release the pressure. After the pressure is released, the pressure inside the container is less than the elastic force of the exhaust spring 12, and the container and cover will return to a sealed state.

[0024] Example 2

[0025] like Figure 5 As shown, the tank connecting hoop 3 is hinged with a handle 6 for easy lifting. The other structures of Embodiment 2 are the same as those of Embodiment 1.

[0026] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
