Abstract

The invention relates to a safety helmet impact puncture resistance testing device, and belongs to the field of safety helmet testing equipment. The device comprises a box frame; a cover plate is fixed at the top of the box frame; an electromagnet is fixedly arranged on the side wall, facing the interior of the box frame, of the cover plate; an impact hammer is adsorbed on the electromagnet; a bottom plate is fixed at the bottom of the box frame; the bottom plate is horizontally arranged; a guide rail plate is arranged on the box frame; the guide rail plate is arranged uprightly; a mechanical sensor is arranged on the top face of the bottom plate in a sliding mode, the mechanical sensor horizontally slides in the direction of the connecting line of the center of the bottom plate and the guide rail plate; a head mold is fixedly arranged on the mechanical sensor; the bottom of the guide rail plate is hinged to the bottom of the box frame; a hinge shaft is horizontally arranged; the guide rail plate is in a horizontal state after rotating by 90 degrees with the hinge shaft as a rotating shaft, and at the moment, the top surface of the guide rail plate is flush with the top surface of the bottom plate, and the mechanical sensor slides on the guide rail plate and the bottom plate. According to the device, the test scene of a safety helmet is improved, and the test result of the safety helmet is more real.

Description

technical field [0001] The present application relates to the field of safety helmet testing equipment, in particular to a safety helmet impact resistance puncture test device. Background technique [0002] At present, safety helmets are protective measures that must be worn when entering and leaving the construction site. The hats that protect the human head from injuries caused by falling objects and other specific factors are called safety helmets. [0003] The existing Chinese patent whose notification number can be referred to is CN104251765A discloses a safety helmet testing device for electric power, including a pole, a round pile welded on the top side wall of the pole, an electromagnet and a base, and the bottom of the pole is welded on the On the base, the bottom surface of the base is equipped with four rollers; the electromagnet is fixed on the round pile and faces downward, and is used to absorb auxiliary heavy objects when electrified; a sensor is installed on ...
