Abstract
The utility model relates to an improved construction safety helmet, which effectively solves the problem of incomplete protection effect of the safety helmet; the technical scheme includes that the helmet comprises a helmet main body, wherein an arc-shaped force unloading plate parallel to the helmet main body is installed at the top of the helmet main body, vertical plates extending downwards are arranged on the left side and the right side of the force unloading plate, the lower end of each vertical plate is hinged to the lower side of the outer wall of the helmet main body through a transverse shaft, the transverse shafts on the two sides are coaxial, the force unloading plate can rotate forwards or backwards around the two transverse shafts, and a torsion spring is installed on each transverse shaft, so that the force unloading plate is located at the top of the helmet main body when not stressed; the utility model discloses a protection of the formula of unloading avoids the workman head to bear thereby openly to strike or injure by the shake, than the more effective protection workman head of traditional safety helmet.
Description
Technical Field
The utility model relates to a construction safety field specifically is improved generation construction safety helmet.
Background
The safety helmet is an important protective tool during construction of a construction site, and particularly is an important guarantee for protecting the life safety of workers in high-altitude falling risk construction environments such as high-rise building construction and viaduct beam construction; the existing safety helmet mainly comprises a high-strength shell and an internal buffer net, can bear high-strength impact without breaking, protects the head of a worker from being directly hit by a falling object, and belongs to hard-resisting protection; however, the falling object has a large impact force, and although the safety helmet can greatly reduce the trauma caused by the falling object, the head of a worker still can be greatly oscillated by the strong impact force, so that internal injuries such as concussion and craniocerebral injury are easily caused.
Disclosure of Invention
To above-mentioned condition, for overcoming prior art's defect, the utility model provides an improved generation construction safety helmet, the effectual incomplete problem of safety helmet protective effect of having solved.
The technical scheme of its solution is, improved generation construction safety helmet, including the safety helmet main part, the curved board of unloading rather than parallel is installed at safety helmet main part top, both sides all are equipped with a riser that stretches out downwards about the board of unloading, the lower extreme of every riser all hinges the downside at safety helmet main part outer wall through a cross axle, the cross axle of both sides is coaxial, unload the board and can rotate forward or backward around two cross axles, all install a torsional spring on every cross axle, lie in the top of safety helmet main part when making the board of unloading not atress.
The utility model discloses a protection of the formula of unloading avoids the workman head to bear thereby openly to strike or injure by the shake, than the more effective protection workman head of traditional safety helmet.

Fig. 3 is a right side sectional view of the present invention.
Fig. 4 is a right side view of the utility model when falling object falls.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
By figure 1 to figure 4, the utility model discloses a safety helmet main part 1, 1 top of safety helmet main part is installed rather than parallel curved power board 2 that unloads, unload power board 2 about both sides all be equipped with a riser 3 that stretches out downwards, every riser 3's lower extreme all articulates the downside at 1 outer wall of safety helmet main part through a cross axle 4, the cross axle 4 of both sides is coaxial, unload power board 2 and can wind two cross axles 4 forward or backward rotations, all install a torsional spring 5 on every cross axle 4, make and unload the top that is located safety helmet main part 1 when power board 2 does not receive the force.
The top of the force unloading plate 2 is provided with a guide strip 6 extending from the left ear to the right ear, and the section of the guide strip 6 is in a wedge shape with a backward inclined surface; when the heavy object falls on the top of the force unloading plate 2, the guide strips 6 can enable the heavy object to deviate towards the rear side, impact force is dispersed towards the rear side, and the heavy object is prevented from smashing the force unloading plate 2.
A buffer net 7 is arranged in the safety helmet main body 1, and a gap is formed between the buffer net 7 and the inner wall of the safety helmet main body 1; when the safety helmet main body 1 is impacted, the buffer net 7 buffers the impact, and the head of a worker is protected.
The utility model discloses the theory of operation does: when an overhead falling object falls and smashes on the force-unloading plate 2, if the smashing point is on the front half part of the force-unloading plate 2, the force-unloading plate 2 is stressed to rotate towards the front side around the rotating shaft, so that the falling object falls in front of the body of a worker, similarly, if the smashing point is on the rear half part of the force-unloading plate 2, the force-unloading plate 2 is stressed to rotate towards the rear side around the rotating shaft, so that the falling object falls behind the body of the worker, if the falling object falling position is right opposite to the top of the force-unloading plate 2, the falling object can be smashed on the guide strip 6, the falling object is deviated towards the rear side under the action of the guide groove, so that the falling object rotates towards the rear side, and the falling object falls behind the body of the worker; through the cooperation of the guide strips 6 and the force unloading plates 2, no matter where the force unloading plates 2 are hit by a falling object, the force unloading plates 2 can rotate, the downward impact force of the falling object can be decomposed into forward or backward component force by the rotation of the force unloading plates 2, the forward impact of the falling object on the safety helmet main body 1 is greatly reduced, and the head of a worker is protected from being hit and damaged by shock.
The utility model discloses an unload power effect of unloading of power board 2 and gib block 6, will fall the thing and strike the forward of 1 main part of safety helmet and decompose into forward or backward component, thereby avoid the workman head to bear and openly strike and be hindered or injure by a crashing object by the shake, more effective protection workman head than traditional safety helmet.
