Description

Technical Field

[0001] The utility model relates to the technical field of distance measuring devices, in particular to a portable laser distance measuring device for monitoring bridge construction. Background Art

[0002] Laser distance measurement uses laser as a light source to measure distance. According to the working mode of laser, it can be divided into continuous laser and pulsed laser. The common laser distance measurement device is laser distance meter. When working, laser distance meter emits a very thin laser beam to the target. The laser beam reflected by the target is received by the photoelectric element. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target. Existing laser distance meters are mostly operated manually by hand. When the handheld laser distance meter measures the distance, the laser distance meter is prone to tilt. Because the tilt angle is small, it is usually not easy for the measured person to observe, resulting in errors in the measurement of distance.

[0003] A Chinese patent discloses a portable laser rangefinder (authorization announcement number CN 220040767 U). The patented technology enables the rangefinder body to be held. At this time, the anti-slip strip can increase the friction between the hand and the skateboard, thereby facilitating the sliding of the skateboard. The cover can be pulled by a pull rope to rotate it about the connecting shaft, so that the cover can be opened with one hand during use, which is more convenient. However, common laser rangefinders lack a protective mechanism, and the laser rangefinder is prone to collision and wear with external objects, and is easy to fall when the rangefinder is taken, resulting in a reduced service life of the laser rangefinder.

[0004] Therefore, those skilled in the art provide a portable laser rangefinder device for bridge construction monitoring to solve the problems raised in the above background technology. Utility Model Content
