Description
Technical field
The utility model relates to a kind of test apparatus of shock-testing, particularly a kind of steel ball shock of a fall tester.
Background technology
For fear of safety goggles, the danger that the imitated protection toys such as mask or the space helmet produce injury children eyes due to the damage of manufactured materials, this type toy all must carry out shock of a fall test before dispatching from the factory, each state all works out strict shock of a fall testing standard, as international standard ISO8124 to the requirement of shock of a fall test is: be that 16 ± 0.15 millimeters and weight are that the uniform steel ball of quality of 16.9 ± 0.7 grams is from the appointed part of the free dropping shock test specimens of height of 130 ± 0.5 centimetres by diameter, whether observation be there is dangerous sharpened edge or dangerous pointed tip and the loosening part that can enter eyes by shock-testing sample, with this, judge whether test specimens meets corresponding toys standard.Yet the testing standard of various countries only has less parameter request, do not mention actual testing tool, different toys enters country variant and need to test by different standards.At present, this test mostly assists to have divided the work by two to three testers, and the consistance of test result is unsatisfactory, the consistance of test, and repeatability, repdocutbility all can not be guaranteed.
Utility model content
For solving existing problem in above-mentioned prior art, the utility model provides a kind of test apparatus of shock-testing.
The utility model adopts following technical scheme to realize:
A kind of steel ball shock of a fall tester, it is characterized in that: comprise test board, be fixed on testing jig, conduit, steel ball on test board, described conduit is hollow tube, the internal diameter of described conduit is greater than the diameter of described steel ball, described conduit one end is provided with extension, and the vertical described test board of described conduit is fixedly connected with described testing jig.
Preferably, described conduit is fixedly connected with by screw thread with described extension.
Further, the length of described conduit is 117 centimetres, and the length of described extension is 3 centimetres.
Preferably, described steel ball is a steel ball or No. two steel balls, and the diameter of a described steel ball is that 15.99 millimeters, weight are 16.53 grams, and the diameter of described No. two steel balls is that 15.99 millimeters, weight are 15.54 grams.
Preferably, described testing jig is provided with at least one support rail that is fixedly connected with described conduit, and described support rail one end and described testing jig are fixed by lateral adjustments nut, and the described support rail other end is the metal hoop of fixing described conduit.
Further, described testing jig is provided with two described support rails.
Preferably, also comprise the brace steel post and the sleeve that support testing sample, described brace steel post two is provided with screw thread, and described sleeve is cylindric, described sleeve lower surface is provided with the threaded hole that coordinates described brace steel post, and described test board is provided with the mounting hole of the described brace steel post of a plurality of installations.
The utlity model has following beneficial effect: the steel ball shock of a fall tester the utility model proposes can meet the test request of country variant, and only need a tester just can complete test.Simple to operate, safety, efficiency is high, and the consistance of test, repeatability, repdocutbility is guaranteed effectively.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
