Abstract

The utility model relates to the technical field of benchmarks, specifically a benchmark for construction, which includes: a bottom box, a measuring tube is installed in the middle of the top of the bottom box, and a fixing mechanism for improving stability is provided in the bottom box. A screw rod is rotatably installed at the bottom of the measuring tube. A standard rod is installed on the outer side wall of the screw rod through thread sliding. The bottom of the screw rod penetrates through the bottom box and is connected to the output end of the lifting motor. The measuring tube The top is equipped with an ash-blocking mechanism to reduce external dust and impurities from entering the measuring tube. The utility model uses the settings of the screw rod and the lifting motor. The lifting motor drives the screw rod to rotate, so that the benchmark rod rises and falls, and the benchmark rod is slidingly connected to the inner wall of the measuring tube. The gap is small, which greatly reduces the dust entering the measuring tube through the gap. At the same time, When there is no need to extend the length, the restoring force of the spring causes the arc-shaped rod to drive the dust shield to block the top of the measuring tube, further reducing the dust entering the measuring tube.
