Description

Technical Field

[0001] The utility model relates to the technical field of fire door production, in particular to a fire door measuring device. Background Art

[0002] Fire doors are doors designed specifically for fire and smoke prevention, as well as personal safety. Their primary function is to prevent the spread of fire, limit the spread of smoke, and provide safe evacuation routes. They are typically located in key areas of a building, such as emergency exits, stairwells, fire escapes, and machine rooms. Fire doors must comply with relevant national or regional fire protection standards and are typically constructed from fire-resistant materials, such as steel and fire-resistant glass. They remain stable in environments with high temperatures, flames, and smoke, resisting deformation or damage. They effectively prevent smoke and flame penetration, minimizing the risk of fire.

[0003] During the production process of fire doors, workers usually use calipers to measure the size of fire doors. When splicing and installing fire doors, they also need to measure the fixing positions of each screw to ensure that the distance between each screw is equal to ensure high fixation of the fire door. However, the calipers currently used are all single rulers. Each time a measurement is taken, horizontal and vertical markings need to be made, and one end of the ruler needs to be aligned to ensure accurate measurement. The operation is cumbersome and affects measurement efficiency.

[0004] Therefore, it is urgent to provide a fire door measuring device to solve the above problems. Utility Model Content
