The invention discloses a
building construction surveying and mapping instrument protection device. The device comprises a tripod, a protection box, a surveying and mapping instrument, driving assemblies, a fixing rod and a trigger
assembly, wherein the fixing rod is arranged on the tripod, the fixing rod is of a hollow structure, open grooves are formed in two sides of the bottom of the fixing rod, the protection box is arranged on the fixing rod, the driving assemblies are symmetrically arranged in the protection box, and the trigger
assembly is arranged on the fixing rod. According to the
building construction surveying and mapping instrument protection device, by means of the trigger
assembly, the driving assemblies and an air bag, the problems that although a triangular supporting frame is good in stability, the triangular supporting frame is prone to toppling over when encountering strong wind or other external factors to cause the damage of an expensive surveying and mapping instrument, and an existing surveying and mapping instrument protection device does not have a protection function after the instrument topples over are solved. An existing surveying and mapping instrument protection device does not have a protection function after an instrument topples over. The invention relates to the technical field of surveying and mapping instruments for
building construction, and particularly provides the building
construction surveying and mapping instrument protection device.
