Abstract
An explosive impact sensitivity tester adopts the structure that a base is fixedly connected with a guide pipe, a drop hammer is mounted at the internal upper part of the guide pipe, a hammer stand is mounted at the lower part, the bottom surface of the hammer stand is movably connected with the base, a punch hammer is mounted in the hammer stand and is opposite to the drop hammer, and the inner wall of the guide pipe is connected with the drop hammer in a sliding manner. The explosive impact sensitivity tester is a testing instrument for teaching experiments, and by adopting the tester, the test accuracy is improved through structurally improving a conventional explosive sensitivity test instrument.
Description
Technical field
The explosive impact sensitivity tester that the utility model relates to is the education experiment testing tool.
Background technology
Traditional education experiment explosive impact sensitivity tester, has base, be connected with conduit above the base, the conduit internal upper part is equipped with and drops hammer, block stamp is equipped with in the bottom, the falling gravity of dropping hammer makes the explosive that is contained between block stamp and the hammer seat be subjected to impulsive force and blasts, thus the sensitivity of testing tested explosive.Owing to drop hammer and be suspended in the conduit, drop hammer and conduit between the space big, dropping hammer hard-corely freely falls, and pounds centre-of gravity shift takes place on block stamp sometimes, directly the accuracy of explosive impact sensitivity is tested in influence.
Summary of the invention
The purpose of this utility model provides a kind of explosive impact sensitivity tester, can make impulsive force stable, accurate by the improvement to existing sensitivity test instrument structure, improves measuring accuracy.
The technical solution of the utility model is: explosive impact sensitivity tester, has base, be connected with conduit above the base, the conduit internal upper part is equipped with and drops hammer, the hammer seat is equipped with in the bottom, and hammer seat bottom surface and base flexibly connect, and in the hammer seat block stamp is housed, block stamp with drop hammer relatively, it is characterized in that: pipe inner wall is slidingly connected with dropping hammer.
Present technique is because pipe inner wall is slidingly connected with dropping hammer, and during work, dropping hammer can vertical drop, and the impulsive force of generation is stable, balanced, and center of gravity can accurately drop on above the block stamp, makes tested explosive vertically stressed, thereby has improved the measuring accuracy of tester.
Description of drawings
Fig. 1 is the structural representation of the utility model explosive impact sensitivity tester.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the working state schematic representation of explosive impact sensitivity tester.
1 drop hammer among the figure, 2 pin rods, 3 conduits, 4 block stamps, 5 hammer seats, 6 bases, 7 explosives.
Embodiment
Explosive impact sensitivity tester, have base 6, conduit 3, base 6 upper surfaces and conduit 3 are connected, conduit 3 internal upper parts are equipped with and drop hammer 1, and conduit 3 inwalls 1 are slidingly connected with dropping hammer, and drop hammer 1 to be supported by the pin rod 2 that is contained on conduit 3 walls, hammer seat 5 is equipped with in the bottom of conduit 3, hammer seat 5 bottom surfaces flexibly connect with base 6, in the hammer block stamp 4 are housed, block stamp 4 with drop hammer 1 relative.During work, tested explosive 7 is contained in the hammer seat 5, place block stamp 4 above, outwards shift out pin rod 2 then, make and drop hammer 1 according to the deadweight whereabouts, pound on block stamp 4, the explosive 7 that is clipped between block stamp 4 and the hammer seat 5 is stressed, draws the sensitivity of tested explosive by the number of times of the stressed blast of explosive in the experiment of statistics stipulated number.Present technique is because pipe inner wall is slidingly connected with dropping hammer, and during work, dropping hammer can vertical drop, drops on accurately above the block stamp, makes tested explosive vertically stressed, thereby has improved test accuracy.
