Detailed Description
The utility model relates to a testing device for measuring the thrust after the action of explosives and powders, which is specifically described below with reference to the accompanying drawings.
The utility model relates to a testing device for measuring thrust after actions of explosives and powders, which is shown in fig. 1 to 7, and comprises a base 1, wherein the lower bottom of the base 1 is of a circular structure, a sensor 7 is arranged at the center of the bottom of the base 1, and the sensor 7 is fastened on the base 1 by 8M 8 screws. A threaded hole is provided in the middle of the sensor 7, and the adjustment sleeve 3 is provided in the threaded hole, so that the height of the adjustment sleeve 3 can be adjusted by rotating the adjustment sleeve 3. An upper plate 2 is arranged on the upper part of the base 1, the bottom surface of the upper plate 2 is of a circular structure, screw holes are formed in the upper plate 2, the upper plate 2 is installed on the base plate 1 through the screw holes by screws, and the centers of the screw holes correspond to each other.
