Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a benchmark for engineering measurement. Background Art

[0002] A surveying pole is a pole used by people when measuring. The surveying poles used in general projects are used for line determination. Generally, when the line of sight is poor or there is no line of sight, the pole line determination method can be used to measure the center line or intersection of the line.

[0003] A new type of engineering measurement benchmark device is proposed in the Chinese utility model patent with application number 201921070700.2, including a rod body, a telescopic rod, a clamping ring, a pull rod, and a support rod. The lower part of the rod body is provided with an annular plate, the lower surface of the annular plate is connected to the ground, the lower part of the annular plate is provided with a pin, the pin is inserted into the ground, the rod body has a telescopic rod hole, the telescopic rod is adapted to the telescopic rod hole, the telescopic rod is inserted into the telescopic rod hole, the telescopic rod slides in the telescopic rod hole, the spring is placed in the telescopic rod hole, the upper part of the spring is connected to the telescopic rod, the clamping ring has an arc groove, the outer side of the rod body is adapted to the arc groove, the outer side of the rod body is connected to the rod body, the clamping ring has a limit plate, the rod body has a limit plate hole, the telescopic rod has a limit plate slide groove, the limit plate hole corresponds to the limit plate slide groove, the limit plate passes through the limit plate hole and is inserted into the limit plate slide groove, the limit plate slides up and down in the limit plate slide groove, the clamping ring is symmetrically arranged on both sides of the rod body, the clamping ring has a convex plate, the screw passes through the symmetrical convex plates, and nuts are connected at both ends of the screw.

[0004] The above device has been improved by setting the benchmark to be retractable. When it needs to be extended, the pull rod can be slid and removed from the hanging rod. Under the action of the spring, the telescopic rod slides upward until the limit plate slides to the bottom of the limit plate slide groove. It is easy to use. However, when in use, the pin and the rod body are an integrated structure and cannot be stored. After use, there is a certain risk in the process of transporting or moving to the next measuring point. For this reason, we proposed a benchmark for engineering measurement. Utility Model Content
