SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provide a safety helmet with a spring buffer, which can effectively improve the safety.
The technical solution adopted by the present invention to solve the above problems is as follows:
the safety helmet with the spring buffer comprises a helmet body and a fastening belt, wherein two ends of the fastening belt are fixedly arranged on the helmet body, the safety helmet further comprises a helmet top and a spring buffer mechanism, a longitudinal sliding groove is formed in the periphery of the outer side of the helmet body, the spring buffer mechanism is arranged on the outer side of the helmet body, the helmet top is fixed on the spring buffer mechanism, an elastic arm is arranged on the edge of the helmet top, the end portion of the elastic arm is located in the sliding groove in the periphery of the outer side of the helmet body, the spring buffer mechanism comprises a sleeve, an ejector rod, a force-releasing cap and a spring, the sleeve is of a hollow structure, the lower end of the sleeve is of an open shape, a limiting clamping hole is formed in the upper end of the sleeve, a limiting boss is arranged at the lower end of the ejector rod, the upper end of the ejector rod penetrates through the opening of the lower end of the sleeve, the limiting clamping hole and the limiting boss are matched and slidably arranged in the sleeve, the lower end of the sleeve is fixedly arranged on the outer side of the helmet body, the spring is sleeved outside the sleeve and the ejector rod, the force unloading cap is provided with a through hole, and the force unloading cap is sleeved outside the ejector rod through the through hole and is positioned above the spring.
Preferably, the crown is provided with a hole corresponding to the ejector rod, and the crown is fixedly arranged at the upper end of the ejector rod of the spring buffer mechanism through the hole.
Preferably, the longitudinal sliding grooves formed in the periphery of the outer side of the cap body are annular.
Preferably, the number of the spring buffer mechanisms is at least three, and the spring buffer mechanisms are uniformly distributed on the outer side of the cap body.
The utility model adopts the technical proposal to achieve the following beneficial effects:
1. when the falling object hits the middle cap body, the impact force is absorbed by the spring through the spring buffer mechanism, if the impact force is too large, and the spring is difficult to support, the two walls of the force-releasing cap are involved to absorb the impact force, and when the impact force is transmitted to the top of the head, the spring and the force-releasing cap already absorb most energy, so that the head and the neck of a wearer are protected;
2. through the cooperation of elastic arm and spout, can do a spacing for spring buffer gear's shrink, the elastic arm also intervenes simultaneously and absorbs the impact force.
