Safety helmets are mainly composed of a helmet shell, a hat lining, a chin strap and other accessories. The helmet shell consists of a shell, a visor, a brim, a top rib, etc. The hat lining is the general term for the internal components of the helmet shell, which consists of a hat hoop, a hat support, a suction strap, a lining strap, etc. The function of a safety helmet is protection.

[0003] As we all know, the construction industry is one of the most dangerous industries. With the increase of high-rise buildings and high scaffolding, accidents caused by falls from heights and objects hitting people are becoming more and more noticeable. Therefore, construction sites require workers to wear safety helmets.

[0004] When working in high temperatures, wearing a safety helmet is very uncomfortable, a lot of sweat will appear on the head, and the air inside the safety helmet is not circulating, which will cause workers to take off the safety helmet frequently during the work process, posing a great threat to the workers' life safety. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that when working at high temperatures, wearing a safety helmet is very uncomfortable, a large amount of sweat will appear on the head, and the air inside the safety helmet is not circulated, which will cause workers to frequently take off the safety helmet during work, posing a great hidden danger to the workers' life safety. A safety helmet for construction workers is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A safety helmet for construction workers comprises an outer shell, and further comprises: an inner shell fixedly connected to the inner wall of the outer shell, wherein the outer shell and the inner shell are spaced apart to form a first channel, a limiting shell fixedly connected to the inner wall of the inner shell, the limiting shell and the inner shell are spaced apart to form a second channel, and the first channel is communicated with the second channel; a heat dissipation box fixedly connected to the outer shell, wherein a boosting assembly is provided in the heat dissipation box, the heat dissipation box is communicated with the first channel, a through hole is provided on the limiting shell, and a shielding adjustment structure is provided in the limiting shell, and when the shielding end of the shielding adjustment structure rotates, the through hole is blocked or unblocked.

[0009] In order to limit the rotating baffle, further, the bottom of the baffle is fixedly connected to a limit plate, a sliding groove is opened on the inner wall of the limit shell, and the limit plate is slidably connected in the sliding groove.

[0010] In order to improve the heat dissipation effect inside the shell, preferably, a sealing plate is fixedly connected to the bottom of the limiting shell, the sealing plate is in contact with the inner wall of the limiting shell, and heat dissipation holes are opened on the sealing plate, and the heat dissipation holes cooperate with the through holes.

[0011] In order to facilitate pressurized air delivery in the heat dissipation box, the boost component further includes blades, a motor is fixedly connected to the heat dissipation box, the blades are fixedly connected to the output end of the motor through a rotating shaft, and the air outlet end of the blades faces the first channel.

[0012] In order to reduce impurities in the air entering the heat dissipation box, preferably, a protective cover is detachably connected to the open end of the heat dissipation box, and a filter is provided on the protective cover.

[0015] Compared with the prior art, the present invention provides a safety helmet for construction workers, which has the following beneficial effects:

[0016] 1. The construction worker uses a hard hat and blows air toward the top of the head through the through-hole. When the head sweats profusely, the unsealed through-hole allows air in the second channel to circulate and blows the air through the through-hole to the top of the head, cooling the worker's head. This keeps the air inside the hard hat in circulation, preventing the worker from taking off the hard hat during work and improving the worker's life safety.

[0017] 2. The construction workers use safety helmets that can block sunlight through the brim, reducing the risk of direct sunlight hitting the workers' eyes and allowing them to see more clearly;

[0018] 3. When the temperature of the construction worker's safety helmet is appropriate, the baffle is rotated to block the through hole. At this time, the gas in the second channel is blown around the head through the heat dissipation holes, blowing air around the worker's head, thereby improving the worker's comfort while working.

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can blow gas through the through hole to the top of the head to cool the top of the worker's head, thereby keeping the air inside the safety helmet in a circulating state, preventing the worker from taking off the safety helmet during the operation, and improving the worker's life safety.

[0027] Example:

[0028] Reference Figures 1-4A safety helmet for construction workers comprises an outer shell 1, and further comprises: an inner shell 4 fixedly connected to the inner wall of the outer shell 1, wherein the outer shell 1 and the inner shell 4 are spaced apart to form a first channel 3, a limiting shell 6 is fixedly connected to the inner wall of the inner shell 4, the limiting shell 6 and the inner shell 4 are spaced apart to form a second channel 5, and the first channel 3 is communicated with the second channel 5; a heat dissipation box 15 fixedly connected to the outer shell 1, wherein a boosting component is provided in the heat dissipation box 15, the heat dissipation box 15 is communicated with the first channel 3, a through hole 7 is opened on the limiting shell 6, and a shielding adjustment structure is provided in the limiting shell 6, and when the shielding end of the shielding adjustment structure rotates, the through hole 7 is blocked or unsealed.

[0029] The air can be delivered to the first channel 3 through the boost component in the heat dissipation box 15, so that the gas in the first channel 3 is in a circulation state, thereby reducing the temperature in the first channel 3 under high temperature direct sunlight. At the same time, the gas will be synchronously delivered to the second channel 5, and the air in the second channel 5 will flow, so that it will be delivered to the bottom of the limit shell 6 through the through hole 7, and when the blocking end of the blocking adjustment structure rotates, the through hole 7 can be blocked or unblocked.

[0030] It should be explained that the inner wall of the outer shell 1 and the outer wall of the inner shell 4 are fixedly connected via a buffer column, which can improve the impact resistance of the outer shell 1 and the inner shell 4.

[0031] A brim 2 is fixedly connected to the bottom of the shell 1, and a limit frame 14 is provided on the brim 2. The brim 2 can block sunlight, reduce the risk of direct sunlight hitting the workers' eyes, and enable the workers to see more clearly.

When the baffle 11 is reset, the through hole 7 can be unsealed. When a large amount of sweat appears on the head, the through hole 7 in the unsealed state will allow the air in the second channel 5 to circulate, and the gas will be blown to the top of the head through the through hole 7, which is used to cool the worker's head, thereby keeping the air inside the safety helmet in a circulating state, preventing the worker from taking off the safety helmet during work, and improving the worker's life safety.

[0036] In addition, a sealing plate 8 is fixedly connected to the bottom of the limiting shell 6 , and the sealing plate 8 is in contact with the inner wall of the limiting shell 6 . The sealing plate 8 is provided with heat dissipation holes 9 , which match the through holes 7 .

[0037] When the temperature is appropriate, the baffle 11 is rotated to block the through hole 7. At this time, the gas in the second channel 5 will be blown around the head through the heat dissipation holes 9, blowing air around the worker's head to improve the worker's comfort while working.
