Abstract
The utility model relates to a laser distance meter and belongs to the field of hardware tools. The laser distance meter comprises a base plate, a vertical rod, a laser head, a pointer and a protractor, wherein the base plate is a flat plate, the vertical rod is vertically fixed on the base plate, the laser head is fixedly connected with the pointer, the direction of laser rays emitted by the laser head is collinear and opposite to the pointing direction of the pointer, the laser head and the pointer are arranged on the vertical rod through a shared rotating shaft, and the protractor taking the rotating shaft as the circle center is arranged on the rotating surface of the pointer via the vertical rod. The laser distance meter can be used for conveniently measuring the length under complicated operating conditions.
Description
Affiliated technical field
The utility model relates to the hardware ﹠ tools field, especially, is a kind of chi tool.
Background technology
In the engineering survey field, for more short-range measurement, generally all adopt entity chi tool to measure, however when adopting entity chi tool to measure, need the chi body is straight fixing with terminal along measuring top, this is for some complex working conditions, and its operation is very much inconvenient.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of laser ruler, and this laser ruler can be realized linear measure longimetry easily under complex working condition.
The technical scheme that its technical matters that solves the utility model adopts is: this laser ruler comprises substrate, vertical rod, laser head, pointer, protractor, described substrate is an one flat plate, described vertical rod is vertically fixed on the described substrate, described laser head and described pointer are fixed, and laser rays direction that described laser head sent and described pointed conllinear are reverse, described laser head and described pointer are arranged on the described vertical rod by common rotating shaft, and described vertical rod is provided with one on the face of walking around of described pointer be the protractor in the center of circle with described rotating shaft.
As preferably, described substrate is a rectangular slab.
As preferably, described protractor place plane parallel is in two of described substrate relative sides.
As preferably, the height of the bottom surface of the described substrate of described rotating shaft distance is unit with the millimeter, and is 10 integral multiple, so that calculate.
The beneficial effects of the utility model are: adopt this laser ruler to measure, only need described substrate is positioned over measurement top, make the projection of the described rotating shaft on the described vertical rod fall within measurement top, rotate described laser head and pointer then, make the laser facula of laser head drop on measuring terminals, the length that can calculate tested distance easily then according to the height and the indicated angle of protractor of described rotating shaft, if the indicated angle of the height of described rotating shaft, protractor, testedly be respectively H, θ, L apart from length, L=H*tan θ then.This laser ruler can be realized linear measure longimetry easily under complex working condition.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
In Fig. 1, Fig. 2, embodiment shown in Figure 3, this laser ruler comprises substrate 1, vertical rod 2, laser head 4, pointer 5, protractor 3, described substrate 1 is an one flat plate, described vertical rod 2 is vertically fixed on the described substrate 1, described laser head 4 and described pointer 5 are fixed, and it is reverse that laser rays direction that described laser head 4 is sent and described pointer 5 point to conllinear, described laser head 4 is arranged on the described vertical rod 2 by common rotating shaft with described pointer 5, and described vertical rod 2 is provided with one on the face of walking around of described pointer 5 be the protractor 3 in the center of circle with described rotating shaft.
Above-mentioned laser ruler, described substrate 1 is a rectangular slab.
Above-mentioned laser ruler, described protractor 3 place plane parallel are in two of described substrate 1 relative sides.
Above-mentioned laser ruler, the height of the bottom surface of the described substrate 1 of described rotating shaft distance is unit with the millimeter, and is 10 integral multiple, so that calculate, as, can be designed as 100mm or 200mm.
For above-mentioned substrate 1 and vertical rod 2, be difficult to distortion in order to make it, can adopt alloy to make, and described vertical rod 2 is welded on the described substrate 1.
Adopt above-mentioned laser ruler to measure, only need described substrate 1 is positioned over measurement top, make the projection of the described rotating shaft on the described vertical rod 2 fall within measurement top, rotate described laser head 4 and pointer 5 then, make the laser facula of laser head 4 drop on measuring terminals, the length that can calculate tested distance easily then according to the height and the protractor 3 indicated angles of described rotating shaft, if the angle of the height of described rotating shaft, protractor indication, testedly be respectively H, θ, L apart from length, L=H*tan θ then.This laser ruler can be realized linear measure longimetry easily under complex working condition.
