Safety helmet for engineering construction entrance

Abstract

The invention relates to the technical field of construction safety, and discloses an engineering construction admission safety helmet which comprises an outer side protector, a mounting groove is formed in the top of the outer surface of the outer side protector, a trigger device is fixedly mounted in the mounting groove, and an air storage device is fixedly mounted in the middle of the top of the outer side protector. When a falling object hits the top of the gas storage bin and hits the position close to the middle of the top of the gas storage bin, due to the fact that the inclination degree is low, the inclined component force borne by the falling object is insufficient, most kinetic energy of the falling object acts on the top of the gas storage device, and the top of the gas storage device is broken down; at the moment, high-pressure gas in the gas storage bin is sprayed out, so that the falling object is slowed down by applying a reverse acting force to the falling object, the kinetic energy of the falling object is reduced as much as possible before the falling object is in contact with the inner-layer protection, the force generated when the falling object collides with the inner-layer protection is reduced, and a wearer is protected to the maximum extent; and the safety performance of the device is improved.

Description

technical field [0001] The invention relates to the technical field of construction safety, in particular to a safety helmet for construction entry. Background technique [0002] A safety helmet is a very common protective device that can protect people's lives at critical moments. It is a device that construction workers must wear on the construction site. In the case of some falling objects, safety helmets can be used. Provides good protection to the head. This helmet is generally semi-circular and is mainly composed of three parts: the shell, the lining and the suspension device. This is also the most widely used safety helmet structure. It has a simple structure and is easy to use. and low cost. [0003] Although the existing safety helmets have the above advantages, there are still some limitations in the actual use process. Since the shape of the helmet is semi-circular, if the high-altitude falling objects are concentrated on the top of the helmet near the center, th...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing safety helmet for engineering construction entrance proposed in the background technology, the present invention provides a safety helmet for engineering construction entrance, which has the advantage of increasing the incident angle of falling objects and solves the problem of falling objects. The problem of greater destructive force when objects are concentrated at the center of the top of the helmet
