Description
Technical Field
The invention relates to a tester, in particular to a novel ball pressure heat-resisting tester.
Background
The ball pressure test is one of the methods for measuring the hardness of plastics and the heat resistance of non-metal materials recommended by the international standardization organization in the field of electrical safety, and during the test, a ball pressure tester with a certain shape is pressed into the surface of the non-metal and non-ceramic materials at a certain temperature for a certain time to test the heat resistance of the structural materials of the electric tool according to the conditions specified by the standard, so that the sample has enough supporting strength under the high-temperature working condition and no electrical safety hidden trouble is caused. The existing ball pressure heat-resisting test device has the disadvantages of complex structure, inconvenient operation and high manufacturing cost.
Disclosure of Invention
Aiming at the defects, the invention aims to provide a novel ball pressure heat-resisting tester which is simple in structure, convenient to operate and low in manufacturing cost.
Therefore, the technical scheme adopted by the invention is as follows:
including load body and backup pad, the backup pad is placed on the bottom plate through the stand, load body lower extreme is the centrum that falls, the lower terminal surface of falling the centrum is the sphere, spherical radius is R2.5mm, the sample has been placed to the up end of backup pad, the lower extreme sphere of falling the centrum is pressed on the sample, load body radial is equipped with the through-hole, install the connecting rod in the through-hole, the both ends of connecting rod overlap respectively has 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.
Furthermore, two ends of the connecting rod are bent downwards and are symmetrical with the center of the connecting rod.
Furthermore, the upper end of the load body is provided with a threaded through hole communicated with the through hole, and a locking screw is arranged in the threaded through hole and used for locking the connecting rod.
The invention has the advantages that:
the invention has simple structure and convenient operation, the two ends of the connecting rod are provided with the adjusting nuts for adjusting the weights at the two ends of the connecting rod to ensure the balance of the two ends of the connecting rod, and the locking screw is additionally arranged at the upper end of the load body to further facilitate the adjustment of the balance degree of the connecting rod.
