Description

Technical Field

[0001] This utility model relates to the field of sealed can lids, specifically a reusable sealed can lid. Background Technology

[0002] In fields such as food storage and laboratory sample preservation, the airtightness of sealed container lids directly affects the preservation effect and storage safety of the contents. With the deepening of environmental protection concepts and the increasing demand for resource conservation, reusable sealed container lids have become the mainstream in the market.

[0003] Traditional sealed can lids are mostly integrated designs, with the silicone ring glued to the lid body or injection molded, making them impossible to disassemble and replace separately. As the core sealing component, the silicone ring is prone to aging and deformation due to high temperature, oil erosion, or frequent friction during long-term use, resulting in a decline in sealing performance. Users need to replace the entire can lid rather than just the silicone ring, which not only wastes the lid material but also increases usage costs. Therefore, a reusable sealed can lid needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a reusable sealing can lid to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reusable sealing can lid, comprising a lid body, an annular groove being formed on the inner side of the lid body, a plurality of through holes being formed on the top of the annular groove, an annular mounting plate being provided on the inner side of the annular groove, a sealing ring being installed at the bottom of the annular mounting plate, and a plurality of support columns passing through the through holes being installed on the top surface of the sealing ring. The support surface has an abutment groove, the cover has multiple sliding grooves, a slider is slidably installed inside the sliding groove, a connecting rod is installed on the top surface of the slider, an abutment block passing through the abutment groove is fixedly installed at one end of the connecting rod, and an adjustment component connected to the slider is installed on the top surface of the cover.

[0006] Preferably, the adjusting assembly includes a threaded rod, which is rotatably mounted on the top surface of the cover. A threaded sleeve is threadedly connected to the outer side of the threaded rod, and multiple connecting plates are hinged to the outer side of the threaded sleeve. The end of each connecting plate away from the threaded sleeve is hinged to the top surface of the slider.

[0007] Preferably, a knob is fixedly installed on the upper end of the threaded rod.

[0008] Preferably, the cross-section of the abutment block is trapezoidal, and one side of the abutment block is provided with an inclined surface for abutting the support column.

[0009] Preferably, the sealing ring is made of silicone.

[0010] Preferably, the inner side of the lid is provided with threads for connection with a sealed container.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This reusable sealing can lid is used to seal the can by screwing the lid onto it. The sealing ring makes tight contact with the can opening to achieve a sealing effect. When the sealing ring needs to be replaced, first turn the knob to drive the threaded rod to rotate. The threaded rod drives the threaded sleeve to move upward. The threaded sleeve drives the connecting plate to rotate. The connecting plate pulls the slider close to the threaded rod. The slider drives the contact block to disengage from the contact groove through the connecting rod. At this time, the sealing ring, annular mounting plate, and support can be moved downward and removed for easy replacement of the sealing ring.

[0012] 2. This reusable sealing can lid, after replacing the sealing ring, annular mounting plate, and support, places the annular mounting plate into the annular groove, ensuring the support passes through the perforation, and pushes the sealing ring upwards, keeping it against the top inner side of the lid. Then, rotate the knob in the opposite direction, causing the threaded rod to move the threaded sleeve downwards. The threaded sleeve moves the connecting plate and slider, which in turn moves the connecting rod and the abutment block, causing the abutment block to insert into the abutment groove. The inclined surface of the abutment block abuts against the inside of the support, applying an upward force to the support and fixing its position. This completes the installation of the annular mounting plate and sealing ring. It uses a modular sealing ring, allowing for replacement of the sealing ring with reduced sealing performance after prolonged use due to aging and deformation. Attached Figure Description
