The utility model content
The deficiency that exists in order to overcome above-mentioned prior art, the utility model provides a kind of becomes with single to survey same easily, the quick and surveying instrument in an angle position still can only be that a cover, quantity do not increase the drop measurement of multi-angle position, also is that cost does not increase relatively substantially, easy a large amount of computer display screen support drop automatic measurement cubings of generally using.
The utility model is to adopt following technical proposals to realize: but a kind of cubing of multi-angle position measurement computer display screen support drop comprises: display screen simulating rod, digital display inclinometer; It is characterized in that: the cylindrical bar that adds parallel this bar on the described display screen simulating rod, weight connects the centering block movable set on cylindrical bar, and can be around the free rotation of this axle, on the weight connection centering block digital display incidence meter is housed, and weight connects centering block take the cylindrical bar axis as reference, and is lower heavy light.
Described cylindrical bar can be contained on the display screen simulating rod by contiguous block.
Thereby this cubing technology make display screen simulating rod weight when the multi-angle position connect centering block because of under heavily go up gently and can remain parallel with the vertical guide of mistake cylindrical bar axis around the relative rotation of cylindrical bar, also just and then this face is parallel all the time relatively for the digital display meter that is installed on it, when just and then the display screen simulating rod is measured in the vertical guide of crossing the cylindrical bar axis pitch angle (drop) is arranged and measured by digital display meter that (also instrument can remain that a direction is constant, guaranteed namely that also the digital display nauropemeter is always the requirement of horizontal positioned in this direction, table is measured) in another perpendicular direction tiltable, therefore it is same quick only to need a cover instrument to get final product, vertical throw when measuring easily display screen arbitrary inclination position, simple structure is compact, have very low cost, and because using instrument few more reliable, the extensive operating conditions of industry spot preferably.
