Embodiment approach 1

[0022] Embodiment 1, distance measurement: directly use the rangefinder module on the instrument body to measure the distance between two points. Two sets of rangefinder modules perpendicular to each other are fixed on the instrument, which can simultaneously measure two perpendicular objects. side length.

Embodiment approach 2

[0023] Embodiment 2, level measurement: place the instrument on the surface of the object or magnetically attract it to the object, and judge the level of the object by observing the position of the level bubble in the horizontal direction. At this time, the instrument acts as a level. For the first measurement, after aligning the end of the instrument with the starting point of the object in any state, measure the distance from the starting point of the object to the other end point, which is the length X1 value of the object, through the rangefinder; for the second measurement, place the instrument After adjusting the level, also measure the length X2 of the vertical projection section from the starting point of the object to the other end point through the rangefinder; compare the second measurement value: when X1≠X2, the object is in a tilted state, and the distance between the object and the horizontal line The angle is α, and the height difference between the starting poi...

Embodiment approach 3

[0024] Embodiment 3, verticality measurement: the detection principle is the same as the horizontal state, first measure the length value Y1 of the object, and then measure the height difference Y2 between the two ends of the object after leveling the instrument, when the measured value Y1=Y2, determine the object It is a vertical state, otherwise it is an inclined state. The angle between the object and the vertical line is α, and the horizontal displacement between the starting point of the object and the other end point is H.

Abstract

The invention discloses a handheld multifunctional laser measuring instrument. An instrument body is provided with three laser emission ports in total, and the laser emission ports are used for emitting laser of a laser tube; two laser emission ports are respectively formed at the left side and the right side along the horizontal direction above the front elevation of the device and can emit alongthe same straight line; a downward laser emission port is also formed in the lower part of the instrument body, the laser beam of the downward laser emission port is in 90-degree orthogonality with the two laser beams at the upper part along the horizontal direction, and a laser distance meter module is fixed inside the instrument body; the instrument body is provided with at least four circularhorizontal bubble meters and at least two columnar horizontal bubble meters which are used for monitoring the leveling of the instrument body in various placement conditions. The handheld multifunctional laser measuring instrument provided by the invention is convenient to carry and handheld, is convenient and fast to operate, does not need to set up a tripod, and can visually display the measureddata in real time. The handheld multifunctional laser measuring instrument has a wider application scope in the fields such as building structures, installation and assembly construction, and can greatly reduce measuring time and cost.

Description

technical field [0001] The invention belongs to the field of building construction engineering measurement, in particular to a hand-held multifunctional laser measuring instrument. Background technique [0002] At present, there are all kinds of measuring instruments in the field of building construction measurement, but each measuring instrument only has one measurement function. If it is necessary to control multiple dimensions of the same building or component construction, it is necessary to use multiple measuring instruments. Finish. The operation is complicated, and the data cannot be displayed quickly and intuitively for analysis. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held multi-functional laser measuring instrument, which is hand-held and easy to carry. It is easy to operate without setting up a tripod, and the measurement data can be displayed intuitively in real time. The instrument d...
