Description

Technical Field

[0001] The utility model relates to the field of fixing devices, in particular to a fixing device for a laser rangefinder. Background Art

[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. The measurement range of laser rangefinder is 3.5-5000 meters. According to the distance measurement method, it is divided into phase method rangefinder and pulse method rangefinder. Pulse laser rangefinder emits a beam or a series of short pulse laser beams to the target when working. 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. Phase method laser rangefinder detects the distance by detecting the phase difference between the emitted light and the reflected light when propagating in space. Laser rangefinder is light in weight, small in size, simple to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders.

[0003] After searching, a laser rangefinder fixing frame with the publication number of CN201822224273.0 is specifically disclosed, including a workbench, a limit plate, a clamping block, and a spring. The limit plate is arranged above the workbench, a sponge pad is arranged inside the limit plate, the clamping block is arranged on the side of the sponge pad away from the limit plate, the spring is arranged on the side of the clamping block away from the sponge pad, a pull rod is arranged inside the spring, and a hand handle is arranged on the end of the pull rod away from the clamping block, a rotating column is arranged below the workbench, a connector is arranged below the rotating column, a telescopic column is arranged below the connector, and an adjuster is arranged on the side of the telescopic column. The beneficial effect is that the utility model has a simple structure and is very convenient to use. It can be used as a fixing frame for laser rangefinders of various models, which greatly improves the versatility of the laser rangefinder fixing frame and also ensures the measurement accuracy of the laser rangefinder.

[0004] However, the above device still has certain defects. For example, the existing laser rangefinder is often placed directly on the ground when in use. Since there is a lot of dust in construction sites or renovated houses, the laser rangefinder will be stuck with dust when placed on the ground. Some laser rangefinders are made of rubber material on the outside, which is difficult to clean after being stuck with dust. In addition, since the outside of some laser rangefinders has an arc, it is not convenient to place the laser rangefinder stably. Secondly, workers will carry small laser rangefinders with them. If the laser rangefinder falls during the movement of the workers, it will cause damage to the laser rangefinder.

[0005] Therefore, it is necessary to invent a laser rangefinder fixing device to solve the above problems. Utility Model Content
