Description

Technical Field

[0001] The present application relates to the technical field of engineering quality inspection, and more specifically, to a wall sampling device for real estate engineering quality inspection. Background Art

[0002] With the development and progress of society, more and more cities are vigorously developing the real estate industry. Similarly, when the houses in a community are built, special personnel are needed to inspect the quality of the house. It is necessary to drill a hole on any wall of the house in the community and take out the wall sample for inspection. This requires the use of a wall sampling device. Patent No. CN202122603233.9 is a wall sampling device for house inspection. The above-mentioned wall sampling device for house inspection has the following shortcomings: the overall structure is complex, the operation is cumbersome, it does not have a lubrication function, and the drill bit cannot effectively drill into the wall.

[0003] The document with prior art publication number CN 219532533 U provides a wall sampling device for real estate project quality inspection. The device uses a high-speed drilling sampling tube to drill into the wall for sampling, and can completely remove the wall sample. When drilling, it is convenient to spray clean water on the sampling tube to cool it down and lubricate it, thereby improving its drilling efficiency.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, when sampling a thicker wall, a longer sampling tube is required, and since the traditional sampling tube cannot be telescopically adjusted, the sampling depth cannot be adjusted. At the same time, when the device is in use, some dust will be generated during the process of drilling concrete by the sampling tube, which can be easily inhaled by the sampler, causing unnecessary lung damage.

[0005] In view of this, we propose a wall sampling device for real estate project quality inspection. Utility Model Content

The fixed plate 203 is threadedly connected with a plurality of locking screws 205 that abut against the first arc plates 202.

[0032] Reference Figure 2 and Figure 4 and Figure 5 The first curved plate 202 and the second curved plate 204 have the same curvature and inner and outer diameters to ensure that the inner and outer walls can be coplanar after the first curved plate 202 and the second curved plate 204 are adjusted, and the first curved plate 202 is always in a state of connection with the fixed plate 203 through the sliding adjustment of the first curved plate 202 in the arc hole 2031.
