CASING FOR SCHMIDT HAMMER HAVING WATERPROOF AND DUST PREVENTION STRUCTURE

摘要

A protection device for a Schmidt hammer having a waterproof and dustproof structure is disclosed. The present protection device for a schmidt hammer having a waterproof and dustproof structure has a built-in schmidt hammer having a striking rod that operates forward and backward so that the schmidt hammer can be used in a contaminated construction site or in water. A cylindrical case for accommodating the case; A case head which is coupled to one end of the case while maintaining a watertightness and having a draw-out hole through which the striking rod is inserted; A fixing bushing inserted into the case in a state of being coupled to an outer circumferential surface of the Schmidt hammer to fix the Schmidt hammer inside the case without flowing and integrate with the case; A case cap coupled to the other end of the case while maintaining watertightness; And a handle coupled to the outer surface of the case cap at one end thereof for pressing the case toward the hardness measurement object in a state in which the striking rod of the Schmidt hammer is drawn out and brought into contact with the hardness measurement object . According to the present invention, the handle is directly coupled to the case in which the Schmidt hammer is installed, and the striking rod is exposed by the draw-out hole formed in the case head, so that the Schmidt hammer can be safely and securely held from foreign matters such as dust, It is possible to provide a protective effect.;
