Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, and particularly relates to a safety helmet structure. Background Art

[0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. Generally, safety helmets have the functions of buffering and shock absorption, dispersing stress, and have good biomechanical properties, and are widely used in dangerous operation fields such as the construction industry and production workshops.

[0003] After retrieval, Chinese Patent Publication No. CN220545888U discloses a sweat-absorbing structure for a safety helmet, which includes a helmet body. An arc-shaped front lining plate is detachably provided on the front side of the inner wall of the helmet body, and an arc-shaped rear lining plate is detachably provided on the rear side. A front sweat-absorbing cotton sleeve is sleeved on the front lining plate, and a rear sweat-absorbing cotton sleeve is sleeved on the rear lining plate. In the utility model, a front lining plate and a rear lining plate are arranged in the helmet body, and sweat-absorbing cotton sleeves are sleeved on the front lining plate and the rear lining plate. The replacement process of the sweat-absorbing cotton sleeves is simple and rapid. At the same time, the front lining plate and the rear lining plate adopt clamping strips and clamping grooves and are installed on the helmet body, and the installation and disassembly methods are fast; sweat-absorbing cotton strips are arranged on the front lining plate and the rear lining plate to increase the sweat-absorbing amount and improve the sweat-absorbing effect; the structure is simple and the cost is low.

[0004] However, in the above technical solution, the sweat-absorbing effect of the safety helmet is improved by the worker himself / herself replacing the sweat-absorbing cotton sleeve and the sweat-absorbing cotton strip. However, when in the mine, the lighting conditions are not good in some narrow spaces and the replacement cannot be carried out. Moreover, in the mine environment, the soil and coal ash adhered to the worker's body adhere to the surface of the sweat-absorbing cotton strip during the replacement of the sweat-absorbing cotton strip, which will increase the friction and discomfort when the sweat-absorbing cotton strip contacts the human body. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a safety helmet structure for the problems existing in the background art.

[0006] The technical solution of the utility model: A safety helmet structure includes a safety helmet body, which is connected with a cap band, and the cap band is connected with a binding strap; a sweat-absorbing band, which is detachably connected to the cap band; a cleaning component, which is connected to the safety helmet body; in the use state of the cleaning component, the cleaning end of the cleaning component moves vertically along the cap band and scrapes against the sweat-absorbing band.

[0025] Embodiment 2

[0026] As Figures 2-4 shown, a safety helmet structure proposed by the present utility model, compared with Embodiment 1, the detailed structure of the cleaning assembly is described in this embodiment. The cleaning assembly includes a push rod 5, a button 6, a moving frame 7, a sliding assembly 8, a scraper 9, an elastic member 10 and a limiting assembly 11. There are two push rods 5 symmetrically arranged. The push rod 5 is arranged in a through hole opened on the safety helmet body 1, and one end of the push rod 5 is connected to the button 6; the moving frame 7 is connected to the end of the push rod 5 away from the button 6; the cross-sectional shape of the moving frame 7 is n-shaped; the number of the sliding assemblies 8 corresponds to that of the push rods 5, and the sliding assemblies 8 are slidably connected to the safety helmet body 1; in the use state of the sliding assemblies 8, the sliding assemblies 8 move horizontally synchronously with the cap hoop 2; there are two scrapers 9 symmetrically arranged, the scraper 9 is connected to the moving frame 7, and the shape of the scraper 9 fits the cap hoop 2; the scraper 9 is made of the same material as the cap hoop 2, and its thickness is greater than that of the cap hoop 2; the elastic member 10 is sleeved outside the moving rod, and one end of the elastic member 10 is connected to the sliding member; the elastic member 10 is selected but not limited to a spring, and a rubber tube can be sleeved outside the elastic member 10 to prevent hair clamping; the limiting assembly 11 is connected to the moving frame 7; in the use state of the limiting assembly 11, the limiting assembly 11 guides the moving route of the moving frame 7;

[0027] In an alternative embodiment, the limiting component 11 is composed of a guiding strip 12 and a guiding groove 13. The guiding grooves 13 are formed on both sides of the cap hoop 2, and the two guiding strips 12 connected to the moving frame 7 are slidably connected to the guiding grooves 13;

[0028] In an alternative embodiment, the sliding component 8 is composed of a sliding block 14 and a limiting block 15. A through hole for the push rod 5 is formed in the sliding block 14, and the symmetrically arranged limiting blocks 15 are connected to the upper end surface of the sliding block 14. The limiting blocks 15 are slidably connected to the safety helmet body 1; a limiting groove for the sliding of the limiting blocks 15 is formed on the safety helmet body 1;

[0029] In an alternative embodiment, a plurality of convex strips 16 are connected to the opposite sides of the scraping plates 9; the diameters of the convex strips 16 gradually decrease from top to bottom, so that the scraping effect of the scraping plates 9 is better when removing moisture;

[0030] In an alternative embodiment, a plurality of ventilation holes 17 are formed in the safety helmet body 1; the ventilation holes 17 accelerate the air flow speed inside the safety helmet body 1 to reduce the temperature;

[0031] In an alternative embodiment, a plurality of filter meshes 18 are pasted on the safety helmet body 1, and the filter meshes 18 correspond to the ventilation holes 17; the filter meshes 18 are used to filter dust in the air and prevent dust from adhering to the head.

[0032] In summary, when the present utility model is in use, the user can adjust the circumference of the cap hoop 2 through the adjustment knob on the cap hoop 2 to adapt to the head shapes of different people. When adjusting the cap hoop 2, the cap hoop 2 will drive the two moving frames 7 to move synchronously. The moving frame 7 moves with the cap hoop 2 through the engagement of the guiding strip 12 and the guiding groove 13, and keeps the position of the scraping plate 9 in contact with the cap hoop 2. When the staff wears the safety helmet body 1 to work, the sweat-absorbing band 4 connected to the cap hoop 2 can absorb the sweat dripping from the forehead due to sweating. When the sweat-absorbing band 4 is soaked when the sweating amount is large, the staff raises the arm and presses the button 6 with the fingers of both hands to push the push rod 5 to move vertically. The push rod 5 drives the moving frame 7 to move downward and stretch the length of the elastic member 10. The moving frame 7 moves along the guiding groove 13 on the cap hoop 2 through the connected guiding strip 12, so that the two scraping plates 9 move to both sides of the sweat-absorbing band 4. The scraping plates 9 move downward to squeeze the sweat-absorbing band 4 through the smaller gap between them. At the same time, the gap is further reduced by the convex strips 16 on the two scraping plates 9, so as to squeeze out the sweat. After the external force on the elastic member 10 is removed, it rebounds to make part of the structure of the moving frame 7 rise into the notch formed in the safety helmet body 1. Part of the structure of the moving frame 7 still contacts the guiding groove 13 on the cap hoop 2 through the guiding strip 12, so as to always maintain its relative position with the cap hoop 2 and prevent the position of the scraping plate 9 from being deflected due to the adjustment of the cap hoop 2.

[0033] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the relevant technical field, various changes can be made without departing from the gist of the present utility model.
