Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation material testing, in particular to a building thermal insulation material testing device. Background Art

[0002] After searching the patent document with announcement number CN221612606U, the insulation material is limited by four L-shaped limit ribs on the placement plate, and at the same time, the hydraulic telescopic rod is extended to push the placement plate upward, so that the insulation material contacts the bottom surface of the limit plate in the protection box, and then the insulation material is limited and fixed, and at the same time, the servo motor is used to drive the crossbeam to adjust to a suitable height through the lead screw, and then the insulation material is subjected to a free fall impact test by releasing the test ball;

[0003] The patent document requires that the insulation material be limited by four L-shaped limit ribs first, and then the placement plate and the limit plate in the protective box be coordinated to complete the limit fixation. The whole fixation process is cumbersome and not convenient. If the insulation material breaks during the test, large pieces of insulation material can be quickly removed, while small pieces of insulation material will adhere to the inside of the protective box due to static electricity, which is very inconvenient to clean. If the attached small pieces of insulation material are not cleaned, these small pieces of insulation material will rest on the insulation material of the next test. When the test ball is free-falling, the fracture of the insulation material may be aggravated, affecting the test data. Utility Model Content
