The invention discloses a device for measuring impact force of a firework or cracker. The device comprises a round table and a glass box, wherein the glass box is arranged on the surface of the round table. The glass box is composed of an opened-and-closed door plate, four transparent glass side walls and a carrying plate, wherein the opened-and-closed door plate is located at the top; the four transparent glass side walls are connected with the opened-and-closed door plate; and the carrying plate is detachably connected with the four glass side walls through buckles. An air cylinder is arranged in the glass box. A spring clamping jaw used for fixing the firework or cracker is arranged at the tail end of a push rod of the air cylinder. An igniter is further arranged inside the glass box. Flames generated by the igniter are located on the extension line of the stroke of the push rod of the air cylinder. A layer of asbestosed wire gauze is laid on the carrying plate. An anti-skid plastic pad is arranged between the asbestosed wire gauze and the carrying plate. By means of the device, the impact force of the firework or cracker can be measured.
Description
technical field [0001] The invention relates to the field of safety protection, in particular to a device for measuring the impact force of fireworks and firecrackers.
