Abstract
The utility model relates to a firework setting off height measuring apparatus that can measure the setting off height and going off area of fireworks and display shells, which consists of a tripod, a horizontal table and a value setting board, wherein, the horizontal table is arranged on the tripod; the value setting board is arranged on the horizontal table; and a value setting gauge is arranged on the value setting board. The measuring apparatus has simple structure, convenient use and reliable measuring precision.
Description
Affiliated technical field
The utility model relates to the surveying instrument of a kind of fireworks, display shell firing altitude and area of burst, and it is a kind of firework display height-gauge that can take into account multiple measurement function.
Background technology
At present, China firework manufacturer is numerous, and the instrument of measuring the fireworks firing altitude is the instrument of other industry, and complicated operation costs an arm and a leg, and especially is difficult to measure fireworks, covering of explosion time of display shell emission penetrated area.
Summary of the invention
Penetrate area in order to overcome the firing altitude that does not have instrumentation measurement fireworks, display shell and to cover, the utility model provides a kind of firework display height-gauge, this measuring instrument can not only be measured the firing altitude of fireworks, display shell and cover and penetrate area, and can take into account other multinomial functions.The technical scheme that its technical matters that solves the utility model adopts is:
Horizontal table top is set on tripod, at the horizontal table top setting definite value plate vertical with horizontal table top, the definite value table is set on the definite value plate, during measurement fireworks are placed on the setting measurement range points, indicate residing definite value by measuring horizon bar, the i.e. firing altitude of fireworks, display shell as can be known, by measure fireworks respectively or simultaneously, display shell covers diameter top and the bottom of penetrating, can draw covering of fireworks, display shell and penetrate area.
At the definite value front edge of board amount transparent hornwork is set, can and cover at the height of measuring fireworks, display shell penetrate area in, the squit angle of going back energy measurement fireworks, display shell.
The beneficial effects of the utility model are: the result is simple, and is easy and simple to handle, is applicable to that detection unit and manufacturer are personal, and producer is improved the quality of products bigger help.
