[0002] Safety helmets are essential safety protection equipment in construction projects, mainly used to protect workers from head injuries at construction sites. Safety helmets can protect workers' heads during construction and effectively reduce head injuries caused by falls, collisions, impacts and other accidents. Construction engineering safety helmets are important protective equipment to protect workers' lives. Correctly wearing and using safety helmets can effectively reduce the risk of head injuries at construction sites. In construction projects, workers may face dangers such as falling objects, collisions, and impacts. Wearing safety helmets can reduce the risk of head injuries. Safety helmets have good cushioning properties. When the head is impacted, the safety helmet can disperse the impact force and reduce the degree of injury to the head. The shell and lining of the safety helmet have a certain strength, which can prevent the penetration of sharp objects and avoid serious head injuries.

[0003] If the hard hat is not worn firmly, it may not provide effective protection in the event of an emergency, leading to head injuries. At the construction site, the hard hat may fall off when it is impacted or vibrated, and workers need to always pay attention to whether the hat is still on their heads, which will distract them from their work and increase the risk of accidents. Wearing an unstable hard hat may cause discomfort to workers, which in turn affects work efficiency and productivity. Existing hard hats are generally fixed by binding, that is, the hard hat is fixed to the head with a strap. This fixing method is troublesome and unstable, and it is easy to loosen during work.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-2 As shown, a multi-protection structure of a helmet proposed by the utility model comprises a protective shell 1, a support body 3 located in the protective shell 1, and also comprises: a universal buffer mechanism, which is installed between the protective shell 1 and the support body 3, and the universal buffer mechanism flexibly connects the protective shell 1 with the support body 3, so that the protective shell 1 can rotate at any angle on the support body 3, and the universal buffer mechanism comprises a connecting sleeve 301 fixedly installed on the support body 3, a connecting seat 302 rotatably installed on the connecting sleeve 301, and a plurality of connecting columns 303 rotatably installed on the connecting seat 302, and the other end of the connecting column 303 is rotatably connected to the protective shell 1. When an object hits the helmet, it will cause a large impact force, which will affect the safety of the human body. At the same time, the impact force of the helmet after being hit will be directly transmitted to the head and spine, both of which are important organs of the human body. Once affected If the protective shell 1 is damaged, it will cause irreparable danger. When the protective shell 1 is subjected to a lateral impact, a lateral force will be applied to the protective shell 1, and the applied lateral force will drive the connecting seat 302 to rotate through the transmission of the connecting column 303, thereby causing the protective shell 1 to rotate. When the protective shell 1 is subjected to a force in the vertical direction, a vertical force will be applied to the protective shell, driving the connecting column 303 to rotate, causing the protective shell 1 to shake on the support body 3, thereby causing the protective shell to tilt, and causing the falling objects falling on the protective shell 1 to slide down along the tilted direction of the protective shell 1, thereby generating a force unloading effect on the impact, thereby starting a buffering effect on the impact, and the force in any manner can be unloaded through the rotation and tilting of the protective shell 1, realizing a buffering force unloading effect at any angle, preventing the impact force of the safety helmet after being hit from being directly transmitted to the head and spine.

[0025] like Figure 1-2As shown, a buffer pad 2 is fixedly installed on the support body 3, and the buffer pad 2 is located between the protective shell 1 and the support body 3. The buffer pad 2 buffers the impact. The buffer pad 2 can absorb part of the impact force, reduce the damage to the head caused by the impact force, disperse the impact force, reduce the pressure on the head, reduce the risk of head injury, and can effectively absorb shock when impacted to protect the head and brain from damage.

[0026] like Figure 3-5 As shown, it also includes a locking mechanism, which is installed below the support body 3. The locking mechanism includes a fixing rope 4. The locking mechanism retracts and fixes the fixing rope 4. The fixing rope 4 is fixedly installed at the bottom of the connecting seat 302. The locking mechanism includes a winding column 6 rotatably installed on the fixing rope 4 by a lock box 5, a ratchet 501 fixedly installed on the lock box 5, a swivel 502 rotatably and slidably installed in the lock box 5, a connecting seat 505 fixedly installed on the swivel 502, and a ratchet 503 rotatably installed on the connecting seat 505. A notch 504 is provided on 502, and a torsion spring 506 is fixedly installed on the connecting seat 505. One end of the torsion spring 506 is fixedly connected to the connecting seat 505, and the other end is fixedly connected to the pawl 503. The lock box 5 is slidably connected to the fixed rope 4, and the winding column 6 is fixedly connected to the rotating ring 502. When wearing, the lock box 5 is placed under the chin, and then the rotating handle 7 is turned to drive the rotating ring 502 to rotate, thereby driving the winding column 6 to rotate, so that the fixed rope 4 is rotated and contracted, so that the fixed rope 4 is wound around the winding column 6, so that To achieve the contraction of the fixed rope, when contracting, the swivel 502 drives the pawl 503 to rotate. When the pawl 503 moves with the swivel 502, the ratchet 501 squeezes the pawl 503, causing the pawl 503 to rotate and enter the notch 504. When the ratchet 501 does not squeeze the pawl 503, the pawl 503 is reset under the action of the torsion spring 506. When the swivel 502 moves in the opposite direction, the ratchet 501 will limit the pawl 503, and the pawl 503 will press against the swivel 502. , unable to rotate, and thus the swivel 502 cannot rotate in the opposite direction, and thus the winding post 6 cannot rotate in the opposite direction, thereby preventing the fixing rope 4 from loosening. When you want to take off the helmet, pull the handle 7 outward to drive the swivel 502 to move outward, thereby causing the pawl 503 and the ratchet 501 to be misaligned, and then the swivel 502 can be freely rotated, thereby loosening the fixing rope 4. When wearing it again, you only need to squeeze the handle 7 inward to make the pawl 503 engage with the ratchet 501 to fix the fixing rope 4 again.

[0027] Working principle: when wearing, place the lock box 5 under the chin, then turn the handle 7 to drive the swivel 502 to rotate, and then drive the winding column 6 to rotate, so as to rotate and shrink the fixed rope 4, so that the fixed rope 4 is wound around the winding column 6, so as to shrink the fixed rope. When shrinking, the swivel 502 drives the pawl 503 to rotate. When the pawl 503 moves with the swivel 502, the ratchet 501 squeezes the pawl 503, so that the pawl 503 rotates and enters the notch 504. When the ratchet 501 does not squeeze the pawl 503, the pawl 503 is reset under the action of the torsion spring 506. When the helmet is to be taken off, the handle 7 is pulled outwards to drive the rotating ring 502 to move outwards, so that the pawl 503 and the ratchet 501 are misaligned, and the rotating ring 502 can be freely rotated, thereby loosening the fixing rope 4. When the helmet is to be worn again, the handle 7 is only needed to be pressed inwards so that the pawl 503 and the ratchet 501 are meshed, and the fixing rope 4 can be fixed again.

[0028] When the protective shell 1 is subjected to a lateral impact, a lateral force will be applied to the protective shell 1. The applied lateral force will drive the connecting seat 302 to rotate through the transmission of the connecting column 303, thereby causing the protective shell 1 to rotate. When the protective shell 1 is subjected to a force in the vertical direction, a vertical force will be applied to the protective shell, driving the connecting column 303 to rotate, causing the protective shell 1 to shake on the support body 3, thereby causing the protective shell to tilt, and causing the falling objects falling on the protective shell 1 to slide down along the tilted direction of the protective shell 1, thereby generating a force unloading effect on the impact, thereby starting a buffering effect on the impact, and force in any manner can be unloaded through the rotation and tilting of the protective shell 1, thereby achieving a buffering force unloading effect at any angle, preventing the impact force of the helmet after being hit from being directly transmitted to the head and spine.
