DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1

[0024] like Figure 1-4 The invention discloses a safety helmet with a protective mask, comprising a safety helmet 1, wherein two symmetrical protruding ribs 10 are provided at the center of the top of the safety helmet 1, and the height of the protruding ribs 10 is higher than the height of the outer wall of the top of the safety helmet 1; the above are all prior arts. The present application adds a protective mask 2 to the safety helmet 1 in the prior art to meet the needs of different working occasions.

[0025] like Figure 1As shown, the protective mask 2 in the present application is arranged at the front end of the safety helmet 1, and the protective mask 2 is rotatably connected to the safety helmet 1. The protective mask 2 can be in a vertical state and located at the front end of the safety helmet 1, such as Figure 1 It is shown that in this state, after the person wears the safety helmet 1, the protective mask 2 is located just in front of the person's face to protect the person's face; in addition, the protective mask 2 is provided with a perspective window 20 and a lighting lamp 21, which is convenient for use in a weak light environment; in addition, the lighting lamp 21 in the present application can adopt an emergency high-intensity lighting lamp 21, which has strong light and can provide convenience for night operations.

[0026] In addition, the protective mask 2 can be rotated to a tilted state and located obliquely above the front end of the safety helmet 1, such as Figure 2 In this state, the protective mask 2 is rotated to the upper side of the front end of the helmet 1 and is no longer directly in front of the person's face. When the protective mask 2 is not needed, the protective mask 2 can be rotated as described above so as not to affect the person's vision. In addition, to ensure that the protective mask 2 does not automatically fall off when it is located at the upper side of the front end of the helmet 1, it is fixed at Figure 2 State, the present application sets a clamp beam 5 on the top of the safety helmet 1, such as Figure 3 As shown, the clamping beam 5 is fixedly arranged between the two protruding ribs 10 on the top of the safety helmet 1; and a buckle 4 is provided on the top of the protective mask 2. When the protective mask 2 is in an inclined state and is located obliquely above the front end of the safety helmet 1, the buckle 4 and the clamping beam 5 are engaged with each other, thereby limiting the position of the protective mask 2.

[0027] In the present application, a rotating assembly 3 is provided between the protective mask 2 and the safety helmet 1 to drive the protective mask 2 to rotate. The rotating assembly 3 is provided with two groups, and the two groups of rotating assemblies 3 are symmetrically located on both sides of the safety helmet 1, and the two groups of rotating assemblies 3 are respectively rotatably connected to the two sides of the protective mask 2. Figure 1 As shown, each group of rotating components 3 includes a rotating piece 30, and the two ends of the rotating piece 30 are rotatably provided with a first rotating shaft 31 and a second rotating shaft 32, one end of the first rotating shaft 31 is rotatably connected to the rotating piece 30, and the other end thereof passes through the side wall of the corresponding side of the protective mask 2 and is rotatably connected thereto; one end of the second rotating shaft 32 is rotatably connected to the rotating piece 30, and the other end thereof passes through the side wall of the safety helmet 1 and is rotatably connected thereto; wherein two fixing nuts 33 are respectively provided at both ends of the first rotating shaft 31 for limiting the protective mask 2 and the rotating piece 30; and two fixing nuts 33 are also respectively provided at both ends of the second rotating shaft 32 for limiting the safety helmet 1 and the rotating piece 30. The ends of the first rotating shaft 31 and the second rotating shaft 32 are both fixed with double nuts, thereby ensuring the above-mentioned fixing and tightening, and not easy to loosen. In addition, in the present application, the outside of the fixing nut 33 can be covered with a rubber sleeve of the same color as the safety helmet 1 (not shown in the figure) to make it more beautiful as a whole.

[0028] Such as 3 and Figure 4 As shown, the buckle 4 in the present application includes a crossbeam 40 and a hook 41, the hook 41 is arranged at one end of the crossbeam 40 and is formed integrally with the crossbeam 40; the end of the crossbeam 40 away from the hook 41 is fixed to the center of the top of the protective mask 2 by bolts; the outer edge of the hook 41 forms a convex surface 42, and the inner edge forms a concave hook surface 43. Figure 4 As shown, a small hook 44 is fixedly provided at one end of the hook 41 away from the crossbeam 40. The small hook 44 is integrally formed with the hook 41, and the bending direction of the small hook 44 is opposite to the bending direction of the hook 41. Figure 4 As shown, the small hook 44 is bent upward.

[0029] When the protective mask 2 is rotated to an inclined state and is located obliquely above the front end of the safety helmet 1, Figure 3 As shown, the bumper can pass under the card beam 5, and the protruding surface 42 of the bumper abuts against the card beam 5. Figure 3 The user turns the protective mask 2 clockwise to Figure 3 When the hook 41 passes under the beam 5, the buckle 4 is made of elastic stainless steel and has a certain elasticity. When the hook 41 passes under the beam 40, it will deform to a certain extent and return to its original shape after passing through the beam 5. When the hook 41 passes under the beam 5, the small hook 44 can pass through first, and the protruding surface 42 can pass through with the small hook 44, so that the passing process of the hook 41 is smoother. When the user releases his hand, the side of the protruding surface 42 of the hook 41 close to the beam 40 is connected with the beam 5, as shown in FIG. Figure 3 shown.

[0030] Embodiment 2

[0031] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, only the hook 41 is changed, and the rest of the structure, shape and connection relationship are the same as those of the first embodiment. In this embodiment, the buckle is formed by the cross beam 40 and the hook 41 in one piece, which is the same as the first embodiment, wherein the end of the hook 41 away from the cross beam 40 is provided with an inner buckle 45, and the inner buckle 45 extends to the side close to the cross beam 40, as shown in FIG. Figure 6 Show.

[0032] That is, when the user rotates the protective mask 2 to an inclined state and is located obliquely above the front end of the helmet 1, as shown in FIG. Figure 5 As shown, at this time, the hook 41 passes over the clamping beam 5. When the user releases his hand, the concave hook surface 43 of the hook 41 hooks the clamping beam 5 at one end away from the cross beam 40, wherein the clamping beam 5 is mainly hooked by the inner buckle portion 45 of the concave hook surface 43, thereby fixing the protective mask 2.

[0033] Embodiment 3

[0034] The shape of this embodiment is the same as that of the second embodiment. In this embodiment, the length of the clamping beam 5 is 5 cm, the length of the cross beam 40 in the buckle 4 is 2 cm, and the point 46 on the side of the hook 41 away from the cross beam 40 is the farthest from the straight line distance between the hook 41 and the cross beam 40. The straight line distance between the point 46 and the cross beam 40 is 3 cm. The thickness of the cross beam 40, the hook 41 and the clamping beam 5 in the buckle 4 is 1 cm.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
