AI Technical Summary
Technical Problem
Existing oxygen bomb calorimeters have a long, deep lid, resulting in a large volume, while lift-up lids occupy a lot of overhead space, which cannot meet the needs of certain scenarios.
Method used
Combining lifting and flip-top structures, the device employs an electric push rod and a rotating mechanism. The lid is lifted by the lifting mechanism and then flipped by the rotating mechanism, allowing for flexible opening and closing of the lid.
Benefits of technology
This design achieves a small calorimeter size, making it suitable for scenarios with limited overhead space, thus avoiding the excessive depth of flip-top designs and the space-consuming issues of lift-up designs.

Abstract
This utility model discloses an opening and closing structure for an oxygen bomb calorimeter, including inner and outer barrels and a lid mounted on top of them. A lifting device is installed on one side of the inner and outer barrels, and a rotating device is located above the lifting device. A base plate is provided at the bottom of the inner and outer barrels and the lifting device. The lifting device includes an electric push rod, a fixed shaft, a lifting shaft, and a dust cover; the rotating device includes a rotating shaft, a U-shaped bearing seat, a self-lubricating bearing, a thrust washer, a first bearing fixing seat, and a second bearing fixing seat. When opening the lid, the lid is first lifted by the lifting device, and then the lid is flipped over by the rotating device; when closing the lid, the lid is first flipped in the opposite direction by the rotating device, and then the lid is lowered by the lifting device. This utility model combines lifting and flipping, giving the calorimeter advantages such as small size and suitability for scenarios with limited overhead space.
