Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, and more specifically, to a safety helmet with an anti-collision buffer structure. Background Technology

[0002] During construction, management personnel and construction workers must wear safety helmets when entering the construction site. Safety helmets play a significant role in the safety of construction workers, effectively protecting their heads from impacts and reducing injuries from collisions with external objects, thus protecting their lives. However, existing safety helmets are all structures with an inner liner installed inside the outer shell, relying solely on the strength of the outer shell to resist external forces. Consequently, they can easily break when subjected to excessive impact or being smashed, failing to provide complete protection. Therefore, this utility model proposes a safety helmet with an anti-collision buffer structure. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a safety helmet with an anti-collision and buffer structure, which has the advantages of anti-collision and buffer, and solves the problem that existing devices cannot provide good protection when the collision force is too large.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned goal of providing excellent protection even under significant impact, this utility model provides the following technical solution: a safety helmet with an anti-collision buffer structure, comprising a safety helmet and straps mounted on the safety helmet. The safety helmet is provided with a fixing component, an inner ring component, and an outer ring component. The fixing component is provided with a tensioning component. The inner ring component is provided with multiple movable rods, and a return spring is sleeved on the outside of each movable rod. A top block is provided at one end of each movable rod, and a push block is provided directly above the multiple top blocks. Multiple pressure sensors are provided on one side of the outer ring component, and multiple pipes are provided on the other side of the outer ring component. An inflation component is provided at one end of each pipe.

[0007] In an embodiment of this utility model, a fixing block is provided on both the left and right sides of the safety helmet, and an earmuff is provided on the fixing block.

[0008] In an embodiment of this utility model, a baffle is provided on the outside of the movable rod, the two ends of the return spring abut against the baffle and the inner ring member respectively, a top plate is provided on the other end of the movable rod, and the inner ring member is connected to the inner peripheral wall of the safety helmet and located directly above the fixing member.

[0009] In an embodiment of this utility model, the inner ring is provided with a plurality of fixing holes, the number of fixing holes being the same as the number of movable rods, the movable rods being slidably connected to the fixing holes, and the push block being connected to the inner top of the safety helmet.

[0010] In an embodiment of this utility model, the pressure sensor and the top plate are located on the same straight line, and the number of pressure sensors and the number of the top plate are equal.

[0011] In an embodiment of this utility model, a vent pipe is provided between the plurality of pipes, a plurality of air pumps are provided inside the outer ring, and an air delivery pipe is provided at the output end of the air pump.

[0012] In an embodiment of this utility model, the other end of the air supply pipe is connected to the ventilation pipe, and a controller is provided on the safety helmet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model is equipped with a push block, a pressure sensor, an air pump, and an inflation component. When the safety helmet is subjected to a large impact force, the push block squeezes the top block, causing the top plate to contact the pressure sensor. At this time, the pressure sensor transmits a signal to the controller, which controls the air pump to work and inflate the inflation component. This causes the inflation component to quickly fill with gas, thereby wrapping the worker's head and buffering the impact force, thus improving the protection of the head.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4This utility model provides a technical solution: a safety helmet 1 with an anti-collision buffer structure, including a safety helmet 1 and a strap 2 set on the safety helmet 1. The strap 2 is used to fix the safety helmet 1. The fixing method of the strap 2 includes, but is not limited to, Velcro fixing, elastic band binding, or strap fixing with a buckle. A controller 5 is provided on the safety helmet 1. The safety helmet 1 is provided with a fixing member 11, an inner ring member 3, and an outer ring member 4. An elastic member 12 is provided on the fixing member 11. Multiple movable rods 31 are provided on the inner ring member 3. A return spring 32 is sleeved on the outside of the movable rod 31. A top is provided at one end of the movable rod 31. A push block 35 is provided directly above the multiple top blocks 33. Multiple pressure sensors 41 are provided on one side of the outer ring 4. The pressure sensors 41 are electrically connected to the controller 5. The pressure sensors 41 are set with a predetermined value. When the pressure sensor 41 is squeezed and reaches the preset value, the pressure sensor 41 transmits the signal to the controller 5. Multiple pipes 42 are provided on the other side of the outer ring 4. An inflatable component 43 is provided at one end of the pipe 42. The material of the inflatable component 43 includes, but is not limited to, nylon, polyamide fabric, and polyurethane. The material selected for the inflatable component 43 has good tensile strength, elasticity, and wear resistance.

[0025] In this embodiment, the safety helmet 1 is provided with fixing blocks 13 on both the left and right sides, and earmuffs 14 are provided on the fixing blocks 13. The earmuffs 14 can rotate and can be worn when there is a lot of noise at the construction site to reduce the damage of noise to the ears.

[0026] In this embodiment, a baffle is provided on the outside of the movable rod 31, and the two ends of the return spring 32 abut against the baffle and the inner ring 3 respectively. A top plate 34 is provided on the other end of the movable rod 31. The inner ring 3 is connected to the inner peripheral wall of the safety helmet 1 and is located directly above the fixing member 11. When the safety helmet 1 is subjected to a large impact force, the push block 35 moves towards the side closer to the top block 33 and squeezes the top block 33 during the movement. After the top block 33 is squeezed, it pushes the movable rod 31 to move, so that the top plate 34 moves towards the side closer to the pressure sensor 41 and squeezes the pressure sensor 41. When the pressure sensor 41 receives the squeezing action and reaches the preset value, it transmits the signal to the controller 5.

[0027] The inner ring 3 has multiple fixing holes, the number of which is the same as the number of movable rods 31. The movable rods 31 are slidably connected to the fixing holes, and the fixing holes can limit and support the movable rods 31. The push block 35 is connected to the inner top of the safety helmet 1.

[0028] It should be noted that the pressure sensor 41 and the top plate 34 are located on the same straight line, and the number of pressure sensors 41 and the number of top plates 34 are equal.

[0029] In this embodiment, a vent pipe 44 is provided between multiple pipes 42, and multiple air pumps 45 are provided inside the outer ring 4. An air supply pipe 46 is provided at the output end of the air pump 45, and the other end of the air supply pipe 46 is connected to the vent pipe 44. When the controller 5 receives the signal transmitted by the pressure sensor 41, the controller 5 controls the air pump 45 to start and work, and outputs gas into the vent pipe 44 through the air supply pipe 46. The gas in the vent pipe 44 then enters multiple inflatable components 43 through multiple pipes 42, so that the inflatable components 43 can expand rapidly when the safety helmet 1 is subjected to a large impact force. It should be noted that the amount of gas delivered by the air pump 45 is fixed and is not continuously delivered into the inflatable components 43. The amount of gas delivered depends on the specific needs because the size of the inflatable components 43 used in different models of safety helmets 1 is different. The amount of gas delivered is enough to make the inflatable components 43 expand rapidly and leave a certain space for the gas inside the inflatable components 43 to flow without causing the inflatable components 43 to rupture.

[0030] Specifically, the working principle of this safety helmet 1 with an anti-collision buffer structure is as follows:

[0031] In use, the safety helmet 1 can be adjusted according to the head circumference of the construction worker by adjusting the size of the fixing part 11 through the elastic part 12. Then, the safety helmet 1 is put on the head of the construction worker and fixed with the strap 2. If the noise at the construction site is loud, the earmuffs 14 can be rotated to the ears to isolate some noise and protect the hearing of the construction worker. In addition, if the safety helmet 1 is subjected to a large impact force, the push block 35 will move towards the side closer to the top block 33 and squeeze the top block 33 during the movement. After the top block 33 is squeezed, it pushes the movable rod 31 to move, so that the top plate 34 moves closer to the pressure sensor 41. The device moves to the side and exerts a squeezing effect on the pressure sensor 41. When the pressure sensor 41 receives the squeezing effect and reaches a preset value, it transmits the signal to the controller 5. After receiving the signal transmitted by the pressure sensor 41, the controller 5 controls the air pump 45 to start and work, outputting gas into the ventilation pipe 44 through the air supply pipe 46. The gas in the ventilation pipe 44 then enters into multiple inflatable components 43 through multiple pipes 42, so that the inflatable components 43 can expand rapidly when the safety helmet 1 is subjected to a large impact force, thereby buffering the impact force and protecting the head of the construction worker.

[0032] It should be noted that the specific models and specifications of the fastener 11, the elastic element 12, the strap 2, the pressure sensor 41, the air pump 45, and the controller 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principle of the pressure sensor 41, air pump 45, and controller 5 are clear to those skilled in the art and will not be described in detail here.
