Abstract
The utility model relates to a heat resisting test appearance is pressed to ball. Including the load body and backup pad, the backup pad is placed on the bottom plate through the stand, load body lower extreme is for falling the centrum, the lower extreme of centrum of falling is equipped with R2.5mm's steel ball, the last end face centre of backup pad has placed the sample, the steel ball is pressed on the sample, the load body radially is equipped with the through -hole, install the connecting rod in the through -hole, the both ends of connecting rod are overlapped respectively and are had the weight, the weight can move on the connecting rod, there is adjusting nut at the both ends of connecting rod through threaded connection, adjusting nut is located the outside of weight. The utility model discloses simple structure, convenient operation is through setting up adjusting nut at connecting rod both ends for the weight at adjust connection pole both ends guarantees that the connecting rod both ends are balanced.
Description
Technical field
The utility model relates to a kind of test instrument, particularly relates to a kind of ball pressure heat resistant test instrument.
Background technology
Ball indentation test is that a kind of of ISO (International Standards Organization) recommendation in electrical safety field measures one of method of plastic hardness and heat resistance of nonmetal material, when testing, by standard defined terms, with certain and so on ball indentation test device in certain temperature, regular hour is pushed down into the surface of nonmetal, non-ceramic material to check the test of electric tool structure material thermal resistance, to ensure that sample is under high temperature operating conditions, has enough support strengths, do not cause electrical safety hidden danger.Existing ball pressure heat resistant test apparatus structure more complicated, inconvenient operation, manufacturing cost is high.
Utility model content
For above-mentioned defect, it is simple, easy to operate that the purpose of this utility model is to provide a kind of structure, a kind of ball pressure heat resistant test instrument of low cost of manufacture.
The technical scheme that the utility model adopts for this reason is:
Comprise load body and back up pad, described back up pad is placed on base plate by column, described load body lower end is vertebral body, the lower surface of described vertebral body is sphere, described spherical radius is R2.5mm, the upper surface of described back up pad is placed with sample, the lower end sphere of described vertebral body is pressed on sample, described load body radial direction is provided with through hole, in described through hole, connecting link is installed, the two ends of described connecting link are overlapped respectively and are had counterweight, described counterweight can move on connecting link, the two ends of described connecting link have been threaded connection adjusting nut, described adjusting nut is positioned at the outside of counterweight.
Further, the bending two ends of described connecting link is downwards and with connecting link Central Symmetry.
Further, described load body upper end is provided with tapped through hole and communicates with through hole, is provided with lock-screw and is used for locking connecting link in described tapped through hole.
The utility model has the advantages that:
The utility model structure is simple, easy to operate, by arranging adjusting nut at connecting link two ends, for adjusting the counterweight at connecting link two ends, ensureing connecting link two ends balance, by setting up lock-screw in load body upper end, being further convenient to the quality of balance adjusting connecting link.
