Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, and in particular to a fire safety helmet with lighting function. Background Technology

[0002] Fire safety helmets are part of the equipment used by firefighters during firefighting operations, protecting their heads from falling debris inside the fire scene. In addition to protecting the firefighter's head, fire safety helmets are often equipped with headlamps to provide illumination within the fire area.

[0003] However, the headlamps on existing fire helmets are located at the front of the helmet, which can only illuminate the direction the firefighter is facing. When carrying out firefighting missions, multiple firefighters often enter the fire scene together. When carrying out firefighting and rescue missions, the firefighters entering the fire scene need to locate their teammates in time. On the other hand, the visibility inside the fire scene is low, and objects inside the building are prone to collapse and fall due to high temperature burning. Illuminating only the direction the firefighter is facing is not conducive to observing objects that are prone to collapse in advance.

[0004] Furthermore, the headlamp angle on existing safety helmets is adjustable. The friction between the headlamp and the bracket on the safety helmet is used to prevent the headlamp from rotating accidentally. After long-term use, the connection between the headlamp and the bracket will wear down, resulting in a decrease in the friction between the two, and the headlamp will be in a loose state, resulting in a short lifespan for the headlamp. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fire safety helmet with lighting function, which can illuminate the area around the firefighter, making it easier for other team members to observe the situation around their location, detect collapsed objects in advance, and help firefighters locate their teammates in the fire scene.

[0009] The angle adjustment assembly includes a T-shaped cable tray, a floating sleeve, a U-shaped stop block, a first spring, and a second spring. The T-shaped cable tray has a flipping part and a swinging part. Both the flipping part and the swinging part have external teeth on their outer walls. The floating sleeve is slidably disposed in the base. The inner cavity of the floating sleeve has a first internal tooth. The swinging part extends into the inner cavity of the floating sleeve, and the first spring provides elastic force to make the first internal tooth mesh with the external tooth on the swinging part.

[0010] The flipping part is rotatably connected to the searchlight, the U-shaped stop block is located inside the searchlight, the U-shaped stop block is provided with a second internal tooth, and the second spring provides elastic force to make the second internal tooth mesh with the external tooth on the flipping part.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Please see Figure 1 and Figure 2This utility model provides a fire safety helmet 10 with lighting function, which includes: a helmet body 11 and a lighting module 12. The helmet body 11 is used to protect the firefighter's head, and the lighting module 12 is located on the helmet body 11, which can provide lighting for the firefighter and free the firefighter's hands, making it more convenient for them to perform rescue tasks in the fire scene.

[0031] Please see Figure 2 and Figure 3 The lighting module 12 includes a base 100, multiple searchlights 200, and multiple angle adjustment components 300. The angle adjustment components 300 connect the searchlights 200 and the base 100; the searchlights 200 are connected to the base 100 via the angle adjustment components 300. Preferably, the multiple searchlights 200 are arranged in a circular array around the base 100. That is, the lighting module 12 can illuminate not only the direction the firefighter is facing, but also behind and to the sides, thereby illuminating the surrounding environment of the firefighter's location.

[0032] It is understandable that when firefighters enter a fire scene for rescue missions, they need to quickly determine the location of obstacles. However, human vision is limited, and visibility is low in a fire scene. Simultaneously illuminating all areas where a firefighter is located allows their teammates to observe the environment behind and to the side of the firefighter, which is beneficial for firefighters to explore the internal environment of the fire scene, improves rescue efficiency, and increases the safety factor of carrying out missions in a fire scene. Furthermore, it allows firefighters to quickly locate the location of their teammates, which is beneficial for teamwork in carrying out rescue missions.

[0033] Please see Figure 3 and Figure 4 The angle adjustment assembly 300 includes a T-shaped cable tube 310, a floating sleeve 320, a U-shaped stop block 330, a first spring 340, and a second spring 350. The T-shaped cable tube 310 is provided with a flipping part 311 and a swinging part 312. External teeth 31 are provided on the outer walls of both the flipping part 311 and the swinging part 312. The floating sleeve 320 is slidably disposed in the base 100. The inner cavity of the floating sleeve 320 is provided with a first internal tooth 321. The swinging part 312 extends into the inner cavity of the floating sleeve 320, and the first spring 340 provides elastic force to make the first internal tooth 321 mesh with the external tooth 31 on the swinging part 312.

[0034] The flipping part 311 is rotatably connected to the searchlight 200. The U-shaped stop block 330 is located inside the searchlight 200. The U-shaped stop block 330 is provided with a second internal tooth 331. The second spring 350 provides elastic force to make the second internal tooth 331 mesh with the external tooth 31 on the flipping part 311.

[0035] Existing angle adjustment structures mainly rely on the friction between components to maintain the illumination angle of the lamp. However, after adjusting the illumination angle, wear occurs between the components. Over time, this wear reduces the friction between the components, causing the lamp to become loose. The angle adjustment component 300 disclosed in this application can solve the above problems, as follows:

[0036] The T-shaped cable tray 310 and the floating sleeve 320, and the T-shaped cable tray 310 and the U-shaped stop block 330 are engaged by the external teeth 31. Both the floating sleeve 320 and the U-shaped stop block 330 are movable parts. When the searchlight 200 is rotated, the external teeth 31 press against the first internal teeth 321 (or the second internal teeth 331) and push away the floating sleeve 320 (or the U-shaped stop block 330). After rotation to the correct position, the floating sleeve 320 (or the U-shaped stop block 330) can reset under the elastic force provided by the first spring 340 (or the second spring 350), causing the first internal teeth 321 (or the second internal teeth 331) to re-engage with the external teeth 31, thus fixing the searchlight 200 at the current angle. Preferably, the tips of the first internal teeth 321, the second internal teeth 331, and the external teeth 31 are all arc-shaped.

[0037] Please see Figure 5 and Figure 6 For example, when the searchlight 200 is driven to rotate around the flipping part 311, pressure is generated between the second internal tooth 331 and the external tooth 31 on the flipping part 311, and under the action of this pressure, the U-shaped stop block 330 is driven to move away from the flipping part 311, so that the tooth tip of the second internal tooth 331 abuts against the tooth tip of the external tooth 31. Figure 5 As shown, at this point, the two are no longer engaged, and the second spring 350 is compressed; the U-shaped stop block 330 rotates together with the searchlight 200. When the groove on the second inner tooth 331 aligns again with the tooth tip of the outer tooth 31, the second spring 350 provides elastic force to push the U-shaped stop block 330 toward the flipping part 311, and causes the second inner tooth 331 to engage again with the outer tooth 31 on the flipping part 311, as shown. Figure 6 As shown, if the external force applied to the searchlight 200 is removed at this time, the second inner tooth 331 meshes with the outer tooth 31 to prevent the searchlight 200 from rotating around the flipping part 311.

[0038] The searchlight 200 is locked by the resistance generated when the first internal tooth 321, the second internal tooth 331, and the external tooth 31 mesh. The floating sleeve 320 and the U-shaped stop block 330 can slide and reset through the first spring 340 and the second spring 350, instead of simply relying on friction to lock the searchlight 200. This can effectively reduce the amount of wear between parts when adjusting the lighting angle, thereby improving the service life of the product.

[0039] Please see Figure 2In one embodiment, the base 100 has a docking groove 110, and the helmet body 11 has a docking seat 13 that matches the docking groove 110, allowing the lighting module 12 to be detached from the docking seat 13 for charging. The lighting module 12 and the helmet body 11 are connected via the docking seat 13, facilitating assembly and disassembly.

[0040] In one embodiment, the T-shaped conduit 310 has a hollow structure, providing wiring space and allowing the wires to be installed inside, which helps to prevent the wires from being burned or scratched by fire.

[0041] Please see Figure 4 In one embodiment, an anti-deviation ring 332 is provided on the U-shaped stop block 330 at the position where it contacts the flipping part 311.

[0042] In one embodiment, the searchlight 200 includes an LED panel and a laser emitter.

[0043] Please see Figure 4 In one embodiment, the end of the swing part 312 is provided with a stop protrusion 313, and the floating sleeve 320 is provided with two grooves 322 that match the stop protrusion 313. The T-shaped cable conduit 310 is the laying position of the wire. The stop protrusion 313 and the grooves 322 are used to limit the rotation angle of the searchlight 200 and prevent excessive rotation from breaking the wires in the T-shaped cable conduit 310.

[0044] In summary, the fire safety helmet 10 with lighting function can illuminate the area around the firefighter, making it easier for other team members to observe the situation around their location, detect collapsed objects in advance, and help firefighters locate their teammates in the fire scene.
