Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.

Referring to fig. 1, the embodiment of the safety helmet of the present invention comprises a helmet body 1 and an eye protection device 5.

Referring to fig. 2 and 3, the cap body 1 includes a head cover portion 11, a brim portion 12 connected to a bottom edge of the head cover portion 11, and two mounting portions 13 respectively disposed on left and right sides of the head cover portion 11. Each mounting portion 13 has a through hole 131 extending through the front and rear thereof, and a positioning member 132 disposed in the respective through hole 131.

The eye protection device 5 is mounted on the mounting portion 13, and is provided with two connecting rods 2, two interlocking units 3, and an eyepiece unit 4.

The connecting rods 2 are respectively mounted on the mounting parts 13. Each connecting rod 2 is a through hole 131 which can be adjusted and moved back and forth and is inserted into the corresponding mounting part 13 in a front and back extending manner, and is provided with a pivoting end 21 which is pivoted with the corresponding linkage unit 3 and is provided with a containing groove 211, an avoidance area 23 which is arranged between the pivoting end 21 and the mounting part 13 and is bent outwards and extends back and forth, and a buffer area 24 which is arranged between the avoidance area 23 and the pivoting end 21 and is bent outwards. In addition, each connecting rod 2 is provided with a plurality of clamping pieces 22 which are distributed at intervals in the front-back direction and are used for being detachably clamped and positioned with the corresponding positioning pieces 132 of the mounting part 13. Therefore, each connecting rod 2 can be positioned by the front and rear displacement of the engaging piece 22 in cooperation with the corresponding positioning piece 132 of the mounting portion 13.

In this embodiment, the positioning element 132 is a protrusion, and the engaging element 22 is a concave hole. It should be noted that in other aspects of the present embodiment, the positioning element 132 may be a concave hole, and the engaging element 22 may be a convex block, or other structural combinations that can achieve the same function. In addition, the number of the clamping pieces 22 is not limited, and can be adjusted according to the actual use situation.

The linkage units 3 are respectively pivoted to the connecting rods 2 in the left-right axial direction. Each linkage unit 3 includes a guide arm 31 extending from top to bottom in an inclined manner and pivotally connected to the corresponding pivotal end 211 of the connecting rod 2 in the left-right axial direction at the top end thereof, a connecting arm 33 extending from front to back and pivotally connected to the bottom end of the guide arm 31 and the eyepiece unit 4 in the left-right axial direction at the two ends thereof, and an elastic member 32 mounted on the pivotal end 21 and connected to the guide arm 31.

In this embodiment, each pivoting end 21 further has a first stop 212 located in the accommodating groove 211, the top end portion of each guiding arm 31 further has a second stop 312, and each elastic member 32 is a torsion spring with two ends respectively abutting against the corresponding first stop 212 and the corresponding second stop 312, and constantly has an elastic force for driving the guiding arm 31 to swing back relative to the connecting rod 2. However, in another aspect of the present embodiment, the elastic member 32 is not limited to a torsion spring, and may be a spiral spring. The elastic member 32 may be an extension spring provided between the guide arm 31 and the mounting portion 13. It should be noted that the elastic member 32 for achieving the purpose of the present invention has many types, and the structural design can be adjusted according to the actual use situation.

Referring to fig. 3 and 5, the eyepiece unit 4 includes a lens holder 41 pivotally connected to the front end of the connecting arm 33 at the left and right sides thereof, and a lens 42 disposed on the lens holder 41. The eyepiece unit 4 can be operated to link the link unit 3 to move up and down pivotally relative to the connecting rod 2, and further can change between a storage position (as shown in fig. 5) above the brim 12 and a wearing position (as shown in fig. 3) below the brim 12.

Referring to fig. 2 and 3, when the embodiment of the present invention is used, the head cover portion 11 can be worn on the head of the user, and then the two hands pull the pivoting end 21, so that the connecting rod 2 can be adjusted and positioned to a proper wearing position (see fig. 3). When the connecting rod 2 is adjusted to be positioned, the positioning member 132 of the mounting portion 13 is inserted into the insertion piece 22 corresponding to the connecting rod 2, and temporarily limits the front and back movement of the connecting rod 2 in the through hole 131. The avoidance area 23 can be designed according to the side edge of the different head cover portions 11, so as to prevent the connecting rod 2 from contacting with the side edge of the head cover portion 11 when being adjusted and positioned back and forth. In addition, when the connecting rod 2 is pulled by a user, the buffer area 24 can disperse the stress borne by the avoiding area 23, so that the service life of the connecting rod 2 is prolonged.

In addition, the guide arm 31 and the joint arm 33 are pivotally connected, so that the joint arm 33 can be pivoted to adjust the lens base 41 to a height position most suitable for covering the eyes of the user according to the height difference between the eyes of the user and the head cover part 11.

At this time, the elastic member 32 constantly gives the elastic force to the guide arm 31 to swing backwards, so as to drive the eyepiece unit 4 to approach the face of the user, and the eyepiece unit 4 can be attached to the face of the user more comfortably.

Referring to fig. 3, 4 and 5, when the eyepiece unit 4 needs to be temporarily removed from the face, the lens holder 41 can be pulled forward from the face of the user to the front of the brim 12 (see fig. 4), and then the lens holder 41 can be pulled upward to a position higher than the brim 12 to release the hand, at this time, the backward acting force applied by the elastic member 32 to the guide arm 31 drives the eyepiece unit 4 to move toward the head cover 11, and finally, the eyepiece unit 4 stays at the accommodating position (see fig. 5) attached to the head cover 11.

When the user wants to wear the eyepiece unit 4 again, the lens holder 41 can be pulled forward from the head cover portion 11 to the front of the brim portion 12 by hand (see fig. 4), and the lens holder 41 is pulled downward to a position lower than the brim portion 12 and then the hand is released slowly, at this time, the backward acting force applied by the elastic member 32 to the guide arm 31 drives the eyepiece unit 4 to move toward the face of the user, and finally the eyepiece unit 4 stays at the wearing position (see fig. 3) attached to the face of the user.

To sum up, the utility model discloses safety helmet and eye protector thereof, through the structure of interlock unit 3 can let the user in wearing the safety helmet during convenient with eyepiece unit 4 provides the protection of eye, also can will when not needing to use eyepiece unit 4 accomodate in 12 tops of brim of a hat portion accomodate the position, make the safety helmet has more the protectiveness, also can reach simultaneously conveniently to wear and simply accomodate the effect.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
