Summary of the invention
The purpose of this utility model is that overcoming current fuse clashes into the above-mentioned technical matters existed in Trigger Function test, provides a kind of fuse simulating impact device.
For realizing this kind of fuse simulating impact device, ram has the profile of fuse, described simulating impact device comprises striker, described striker bottom is equipped with spring one, spring one upper end withstands on the face, convex edge on striker, striker is inserted in a hollow tubular, spring one lower end withstands on hollow tubular oral area, hollow tubular offers radial hole, trigger button is provided with in radial hole, described trigger button comprises a right cylinder wall offering through hole, right cylinder is equipped with spring two, spring two is spacing between trigger button and hollow tubular outer wall, striker is located in cylindrical through hole, the position that striker adapts with through hole arranges a neck, hollow tubular upper port periphery is provided with screw thread, upper contact head is hollow shape, internal thread is provided with in upper contact head lower port, upper contact head upper surface is provided with perforation, striker upper end is through upper contact head, the face, convex edge that upper contact head site of perforation press against on striker is threaded connection on hollow tubular, further, lower contact is threaded connection in hollow tubular lower end, further, top flat is fixedly installed at hollow tubular upper oral part, top flat offers striker hole, the diameter in striker hole is greater than striker diameter and is less than spring outer diameter, spring one lower end withstands on top flat, further, described striker comprises head and striker, be threaded between striker with head, convex edge is positioned at head lower end.
Positive Advantageous Effects of the present utility model is: the utility model structure is simple, with low cost, be easy to make, only need a steel pipe can be completed by simple machining, impact can be taked by changing different spring or the convenient adjustment of alternate manner, before power switch cabinet dispatches from the factory, be applied in the Reliability of Microprocessor that can test out associated mechanical mechanism in fuse simulating impact reliably, ensure the quality of product turnout.
