Description

Technical Field

[0001] The utility model mainly relates to the field of indoor quality detection, and in particular to an indoor quality detection device. Background Art

[0002] After the building is built and the indoor floor is poured with concrete, it is necessary to test the indoor concrete floor before delivery. The drill cuts a concrete sample with a diameter of 100mm and a height of 100mm on the concrete floor structure and takes it to the laboratory for testing. The core sampling method can relatively directly and accurately reflect the real situation of the concrete components.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] However, when the core is used to take samples of the concrete floor slab for testing, the concrete sample will fit into the inner wall of the sampling tube, and the sampling tube needs to be knocked to remove the floor slab concrete sample from the sampling tube. However, the knocking process will cause the sample in the sampling tube to break, resulting in incomplete sampling of the concrete floor slab, affecting subsequent testing.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
