Description

Technical Field

[0001] The utility model relates to the field of safety helmets, in particular to a labor protection safety helmet for construction sites. Background Art

[0002] A safety helmet is a protective article for preventing impact objects from hurting the head. It consists of a helmet shell, a helmet liner, a lower cheek strap and a rear hoop. When a worker's head is impacted by a falling object, the helmet shell and the helmet liner of the safety helmet first decompose the impact force onto the entire area of the skull in an instant, and then most of the impact force is absorbed by the elastic deformation, plastic deformation and allowable structural damage of each buffer structure of the safety helmet, so that the impact force finally acting on the worker's head is reduced to below 4900 N, thus playing a role in protecting the worker's head. The helmet shell material of the safety helmet plays an important role in the overall impact resistance of the safety helmet.

[0003] After retrieval, a safety helmet with the publication number CN220554402U relates to the technical field of labor protection articles, and is used to provide a warning for relevant workers when they wear the safety helmet incorrectly fastened, so as to reduce or even avoid the situation of the safety helmet falling off during the operation. The safety helmet includes: a helmet shell, a vibration switch, a normally closed microswitch, a helmet strap, a battery, and an alarm. The vibration switch and the normally closed microswitch are arranged on the helmet shell and are connected in series; one end of the helmet strap is connected to the helmet shell, and the other end is connected to the normally closed microswitch; the battery is located inside the helmet shell and is connected in series with the normally closed microswitch; the alarm is located inside the helmet shell and is connected in series between the vibration switch and the battery. The above safety helmet is used to protect the heads of relevant workers during the operation;

[0004] Based on the above patent, by arranging a vibration switch, a normally closed microswitch, a battery and an alarm in the helmet shell, connecting the alarm, the vibration switch, the normally closed microswitch and the battery in series to form a circuit, and connecting the connection end of the normally closed microswitch to the helmet strap, when relevant workers wear the safety helmet but do not fasten the helmet strap correctly, the vibration switch can be used to connect the above circuit, so that the alarm emits a warning message to remind the relevant workers that the helmet strap is not fastened correctly; when relevant workers wear the safety helmet and fasten the helmet strap correctly, the helmet strap will exert a pulling force on the normally closed microswitch to pull the normally closed microswitch, so that the normally closed microswitch changes from the normally closed state to the open state, so as to disconnect the above circuit and make the alarm stop emitting the warning message. In this way, when relevant workers wear the safety helmet, they can fasten the helmet strap correctly in time, avoid the situation of the safety helmet falling off during the operation, improve the correct usage rate and safety performance of the safety helmet, and can effectively protect the heads of workers. However, the anti-impact effect of this safety helmet is not good, and it is easy to hurt the worker's head when impacted, increasing the risk of work-related injuries for workers, and this safety helmet is not convenient to wear and not easy to adapt to workers with different head shapes, and has poor versatility;

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 、 Figure 2 and Figure 4, An embodiment provided by the present utility model: A labor protection safety helmet for construction sites, including a housing 1 forming the main body of the safety helmet. Multiple concavities and convexities 3 for dispersing impact force are provided on the top side of the housing 1. A lining 5 for improving wearing comfort is fixedly connected to the bottom side of the housing 1. A hoop 7 is fixedly connected to the bottom side of the inner wall of the housing 1. A headband 6 for reducing impact force is fixedly connected to the bottom side of the lining 5. Elastic bands 4 are fixedly connected to the left and right sides of the bottom side of the lining 5. An EPS foam layer 14 is fixedly connected inside the lining 5. An air cushion 15 is fixedly connected to the bottom side of the EPS foam layer 14. A lighting lamp 2 is installed on the front side of the top side of the housing 1. The outer wall of the housing 1 is coated with wear-resistant paint;

[0026] Specifically, when the safety helmet is impacted, the multiple concavities and convexities 3 on the top side of the housing 1 can disperse the impact force and reduce the direct impact on the head. When an impact occurs, the EPS foam layer 14 will compress, which can effectively absorb and disperse the impact force, thereby reducing the degree of impact force transmitted to the head. And the air cushion 15 will also play a certain role in absorbing the impact force and provide a certain degree of comfort. The headband 6 is used to further relieve the impact force on the worker's head. Thus, through the cooperation of the multiple concavities and convexities 3, the EPS foam layer 14 and the air cushion 15, the impact caused by the external impact on the safety helmet is reduced, thereby improving the impact resistance of the safety helmet, enabling the safety helmet to provide better protection ability for the worker, and thus reducing the risk of work-related injuries. The lighting lamp 2 enables the safety helmet to provide lighting during night construction, and the wear-resistant paint coating improves the wear resistance effect of the safety helmet.

[0027] Refer to Figure 2 and Figure 3 , A fixing block 10 is fixedly connected between the two elastic bands 4. Three snap rods 12 are fixedly connected to the end of the left fixing block 10. A slot block 11 is fixedly connected to the end of the right fixing block 10. A snap groove is provided in the middle of the slot block 11. Limiting strips 13 are fixedly connected to both the upper and lower sides of the slot block 11. The upper and lower two snap rods 12 are engaged on the limiting strips 13, and the middle snap rod 12 is inserted into the snap groove. An adjusting strap 9 is fixedly connected to the rear side of the bottom side of the hoop 7. An adjusting block 8 is provided in the middle of the adjusting strap 9;

[0028] Specifically, when the worker puts on the safety helmet on the head, the snap rods 12 are engaged on the limiting groove and the limiting strips 13, thereby connecting the two elastic bands 4 together. Then, the tightness of the adjusting strap 9 is adjusted through the adjusting block 8, so that the safety helmet can better fit the worker's head, ensuring that the safety helmet will not lose its protective effect due to movement during work or activities. Thus, the safety helmet is worn on the head through the snap rods 12 and the limiting strips 13, and the adjusting block 8 and the adjusting strap 9 are used to make the safety helmet adaptable to wearers with different head shapes and head circumferences, thereby improving the versatility and wearing convenience of the safety helmet.

[0029] Working principle: After the worker puts on the safety helmet on the head, the buckle rod 12 is snapped onto the limit groove and the limit strip 13, so as to connect the two elastic bands 4 together. Then, the tightness of the adjustment belt 9 is adjusted through the adjustment block 8, so that the safety helmet can better fit the worker's head, ensuring that the safety helmet will not lose its protective effect due to movement during work or activities. When the safety helmet is impacted, the multiple concavities and convexities 3 on the top side of the outer shell 1 can disperse the impact force and reduce the direct impact on the head. The EPS foam layer 14 will compress when impacted, and can effectively absorb and disperse the impact force, thereby reducing the degree of impact force transmitted to the head. Moreover, the air cushion 15 will also play a certain role in absorbing the impact force and provide a certain degree of comfort. The impact force on the worker's head is further relieved through the headband 6. The safety helmet can provide illumination during night construction through the lighting lamp 2. The wear-resistant effect of the safety helmet is improved through the applied wear-resistant coating.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
