AI Technical Summary
Technical Problem
Existing physical adsorption instruments are prone to liquid nitrogen splashing when the sample tube is inserted into the liquid nitrogen cup, which can cause injury to operators or damage to the equipment.
Method used
Design a protective device for a physical adsorption instrument, including a housing, a protective structure, a fixing structure, and a connecting structure. The protective structure is slidably connected to the housing, and blocks liquid nitrogen splashes by sliding, while being hidden inside the housing to avoid obstructing other operations.
Benefits of technology
It effectively prevents liquid nitrogen splashing, protects operators and equipment, avoids damage, reduces equipment costs, and extends service life.

Abstract
The utility model relates to the field of physical adsorption appearance, specifically provide a protective device and physical adsorption appearance for physical adsorption appearance, aims at solving the problem of liquid nitrogen splashing of physical adsorption appearance in prior art, for this purpose, the utility model provides a protective device for physical adsorption appearance, including casing, protection structure, fixed structure and connecting structure, and protection structure and casing sliding connection, fixed structure sets up on the casing, and fixed structure is detachably connected with protection structure, and connecting structure is used for the sliding connection of protection structure and casing. The protection structure is relative to the casing sliding, when the protection structure slides out from the casing, the protection structure shields physical adsorption appearance to prevent liquid nitrogen splashing. When the protection structure is stored in the casing, the fixed structure can fix the protection structure. Connecting structure can slide the connection of protection structure and casing, so that the movement of protection structure is more smooth. Through the scheme, the problem of liquid nitrogen splashing in the use of physical adsorption appearance is solved.
