Abstract
The utility model discloses a laser detecting instrument for the evenness of a wall surface, which relates to a wall surface evenness detecting instrument made by adopting a laser ranging principle. The laser detecting instrument can determine evenness data of the wall surface precisely and rapidly, and automatically record and store the data, thereby being very convenient in use. The laser detecting instrument comprises a laser rangefinder running rule and a light penetrating hole, wherein the light penetrating hole is arranged on the running rule, a laser rangefinder is installed on the running rule, and a laser emitting hole of the laser rangefinder aligns to the light penetrating hole arranged on the running rule. The laser rangefinder adopted in the laser detecting instrument is a micro laser rangefinder, the thickness of the running rule is 7cm, the measurement accuracy of the laser rangefinder is 0.1mm, and the reading time of the laser rangefinder is 2s. The laser rangefinder is installed on the running rule and can move left and right freely on the running rule. In a measuring process, the laser rangefinder emits laser beams towards the wall surface, the laser beams arrive at the wall surface through the light penetrating hole, the laser rangefinder receives reflective beams, and an evenness error can be calculated according to a time difference between light emitting and light receiving and a traveling speed of light, that is, the distance is obtained by multiplying the time by the speed.
Description
Technical field
What the utility model degree of plainness for wall surface laser detecting apparatus related to is a kind of degree of plainness for wall surface detector that adopts laser distance measuring principle to make, and can measure the wall surface levelling degrees of data accurately and fast, and can write down automatically, store, very easy to use.
Technical background
The degree of plainness for wall surface detector that generally uses on producing at present is made up of guiding ruler and wedge shape clearance gauge.Its method of application is that guiding ruler is pressed close to metope, inserts the wedge shape clearance gauge at slit place, on the wedge shape clearance gauge, reads reading, with read-record on handbook.Use very inconvenience, precision is also low.
Summary of the invention
The utility model purpose is to exist the use inconvenience to the degree of plainness for wall surface detector of being made up of guiding ruler and wedge shape clearance gauge that generally adopts in the market; The situation that measuring accuracy is low; Provide a kind of laser distance measuring principle that utilizes to measure the wall surface levelling degrees of data accurately and fast; And can write down automatically, store, very easy to use.
