Description
TECHNICAL FIELD

[0002] In the field of building engineering quality supervision, the sampler as a key detection tool, its performance and reliability are directly related to the supervision and control of building engineering quality, however, the sampler on the current market has obvious technical defects in the aspects of standardized design, high adjustment and structural stability, these problems not only affect the standardization of detection work, but also may cause the accuracy of sampling data to be affected.
[0003] The first problem is the lack of unified standard sampling equipment, which seriously affects the standardization of detection work: first, the existing technology lacks unified professional equipment for sampling concrete samples or mortar samples, resulting in non-standard sampling methods; second, different construction units use different sampling methods and tools, resulting in a lack of comparability of sampling results; in addition, the lack of professional sampling equipment may also increase human error during sampling; finally, this low degree of standardization not only affects the reliability of detection data, but also increases the difficulty of quality control.
[0004] Second, the sampling equipment is limited in extension adjustment, and there are major use obstacles: first, although the existing technology adopts the innovative design of combining multiple sampling plates to form a sampling claw, the adjustment range of the overall extension length of the equipment is limited; second, the fixed equipment length is difficult to adapt to sampling requirements of different heights, and the operator may need to take unsafe postures for sampling; third, when different height operators use the same equipment, they may need to use external tools or take improper postures such as bending; in addition, this design limitation increases the labor intensity and safety risk of the operator; finally, the lack of flexible adjustment function design seriously limits the practicality and scope of application of the equipment.
[0005] Especially serious is that the height adjustment structure is unstable, and although some improved products have achieved stepless adjustment function, they have serious defects in structural reliability: first, the simple adjustment structure is easily affected by external force during sampling operation and may be displaced; second, environmental vibration may cause the adjusted height to change; third, the lack of structural stability may affect the accuracy of sampling and the safety of operation, and this design of lack of structural stability directly affects the quality and efficiency of sampling work.
