[0002] On construction sites, in mines, and in factory workshops, safety helmets are a solid line of defense protecting workers' lives. They effectively resist impacts from flying objects and debris, as well as accidental collisions, significantly reducing the risk of head injuries. Their application is not only a mandatory safety procedure for enterprises, but also an essential self-protection awareness that every worker must possess.

[0003] To provide more comprehensive protection for workers' heads, a detachable visor can be installed on the safety helmet. Used in conjunction with the helmet, the visor offers more complete protection against impacts from flying objects and debris, as well as accidental collisions, further reducing the risk of head injuries. In lower-risk areas, the visor can be removed to avoid becoming an obstacle or a burden, thus making the helmet more convenient to use.

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] like Figures 1 to 3 As shown, this is a preferred embodiment of a safety helmet cover according to the present invention. The cover includes a clamp 1 and a fastening member 2. The fastening member 2 is installed at the rear end of the clamp 1. The clamp 1 is snapped onto the front edge of the safety helmet and secured to the safety helmet by the fastening member 2. An angle adjustment seat 11 is integrally formed on the clamp 1. A face mask mounting seat 3 and a pivot shaft 4 are also included. The face mask mounting seat 3 is pivotally connected to the clamp 1 via the pivot shaft 4. An angle adjustment part 31 is integrally formed on the face mask mounting seat 3. The angle adjustment part 31 is engaged with the angle adjustment seat 11 in multiple stages. A transparent face mask 5 is snapped onto the face mask mounting seat 3.

[0023] The protective cover of this utility model consists of only a clamping component 1, a fastening component 2, a face mask mounting base 3, a pivot shaft 4, and a transparent face mask 5. The components are simple and few in number. After each component is manufactured, the face mask mounting base 3 is simply pivotally connected to the clamping component 1 via the pivot shaft 4, the transparent face mask 5 is snapped onto the face mask mounting base 3, and the fastening component 2 is installed at the rear end of the clamping component 1. Its manufacturing process is simple and convenient.

[0024] In use, the clamp 1 is snapped onto the front edge of the safety helmet and secured to it with the fastening member 2, thus installing the protective cover onto the safety helmet. Then, by the multi-stage movable engagement between the angle adjustment part 31 and the angle adjustment seat 11, the transparent face shield 5 can be pushed upwards when grasped, allowing for multi-angle adjustment. This method offers the advantages of convenient assembly and use.

[0025] The key feature of this utility model is that the protective cover of this utility model only includes a clamping part 1, a fastening part 2, a mask mounting base 3, a pivot shaft 4, and a transparent mask 5 in terms of structural composition. The components are simple and few in number, and have the advantages of simple product structure, simple production process, high production efficiency and low production cost.

[0026] The aforementioned angle adjustment seat 11 is provided with multiple angle adjustment ribs 111, and the angle adjustment part 31 is provided with multiple angle adjustment grooves 311. The angle adjustment part 31 and the angle adjustment seat 11 are connected by a multi-stage movable locking mechanism through the cooperation of the angle adjustment grooves 311 and the angle adjustment ribs 111. Thus, whenever the transparent mask 5 is grasped and pushed upward at a certain angle, the various levels of angle adjustment ribs 111 will engage with the various levels of angle adjustment grooves 311, thereby realizing multi-angle adjustment of the transparent mask 5.

[0027] The aforementioned fastening component 2 is a fastening spring 21. The fastening spring 21 has hooks 211 at both ends, and the clamping component 1 has through holes 12 at both ends. The fastening spring 21 is mounted on the through holes 12 via the hooks 211. Thus, by providing hooks 211 on the fastening spring 21 and through holes 12 on the clamping component 1, the product structure and manufacturing process offer advantages such as simple structure, simple manufacturing process, high production efficiency, and low production cost.

[0028] The aforementioned protective cover also includes a rubber sleeve 6, which is fitted onto the fastening member 2. Thus, the rubber sleeve 6 provides an anti-slip effect, making the connection between the protective cover and the safety helmet more stable.

[0029] The aforementioned clamp 1 is provided with a snap-fit ​​groove 13, through which the clamp 1 is snapped onto the front edge of the safety helmet. In this way, the clamp 1 is firmly secured to the front edge of the safety helmet through the snap-fit ​​groove 13, thereby making the connection between the protective cover and the safety helmet more stable.

[0030] The aforementioned transparent face mask 5 is provided with a snap-fit ​​hole 51; the face mask mounting base 3 is provided with a U-shaped plate 32, the inner side of the U-shaped plate 32 is provided with a snap-fit ​​seam 33, the U-shaped plate 32 is provided with a snap-fit ​​block 34, and the snap-fit ​​block 34 is provided with an inclined guide surface 341; the transparent face mask 5 is inserted into the snap-fit ​​seam 33 and snapped onto the snap-fit ​​block 34 through the snap-fit ​​hole 51. In this way, the transparent face mask 5 can be installed on the face mask mounting base 3.

[0031] The aforementioned U-shaped plate 32 is provided with an outwardly inclined pull plate 321, and a snap-fit ​​block 34 is disposed on the pull plate 321. Thus, when it is necessary to remove the transparent face mask 5, the snap-fit ​​block 34 can be pulled out from the snap-fit ​​hole 51 by pulling the pull plate 321 to release the snap, and the transparent face mask 5 can be easily removed from the face mask mounting base 3, which has the advantage of being easy to use.

[0032] The upper end of the aforementioned mask mounting base 3 is also provided with a limiting baffle 35. Thus, when the transparent mask 5 is placed in front of the user, the limiting baffle 35 presses against the clamp 1, thereby limiting the position and effectively placing the mask mounting base 3 on the clamp 1, making the protective mask more stable to wear and more convenient to use.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
