AI Technical Summary

Technical Problem

Existing laser rangefinders are not easy to place stably and vertically on the ground, resulting in unstable placement and affecting the smooth progress of distance measurement operations.

Method used

A construction quality acceptance measuring instrument including a side frame assembly was designed. The side frame assembly consists of a bottom protrusion, a connecting groove, a side frame, a damping shaft, a sponge pad, a magnetic sheet, etc. By unfolding and retracting the side frame, the stability and friction of the equipment are enhanced, ensuring stability when placed vertically.

Benefits of technology

The design of the side frame assembly improves the stability of the rangefinder when placed vertically, reduces the risk of tipping over, and enhances the reliability and convenience of distance measurement.

Abstract

The utility model discloses a construction quality acceptance measuring instrument, which comprises a shell, a display screen arranged on the surface of the shell, and keys arranged below the display screen, the side frame assembly comprises bottom protruding blocks symmetrically fixed to the two sides of the bottom end of the shell, connecting grooves formed in the bottom protruding blocks, and side frames with the bottom ends rotationally connected into the connecting grooves. The side frame assembly further comprises a damping rotating shaft, and the bottom end of the side frame is rotationally connected with the shell through the damping rotating shaft. By means of the designed side frame assembly, the stability of the laser range finder in the vertical placement process can be improved, personnel can open side frames on the two sides to be attached to the ground, after the operation is conducted, on one hand, the overall gravity center of the range finder is lowered, on the other hand, the contact area between the range finder and the ground is also increased, and through the design, the laser range finder is more stable. Stability of the distance measuring instrument in vertical placement can be enhanced, the distance measuring instrument is not prone to toppling over, and smooth proceeding of distance measuring work is facilitated.
