[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: a helmet with a magnetic lens, including: a helmet body 1 and a rotating lens 2. The helmet body 1 and the rotating lens 2 are rotatably connected. Magnet positive poles 13 are symmetrically arranged on both sides of the helmet body 1, and magnet negative poles 22 are arranged on both sides of the rotating lens 2. When the rotating lens 2 is completely covered with the helmet body 1, the magnet positive poles 13 and the magnet negative poles 22 are automatically adsorbed to relatively fix the rotating lens 2 and the helmet body 1.

[0028] Hanging grooves 12 are opened on both sides of the helmet body 1, and a rotary button assembly 3 is fixedly installed in the hanging grooves 12.

[0029] Hanging ears 21 are provided on both sides of the rotating lens 2, and the hanging ears 21 are sleeved on the rotary button assembly 3, so that the rotating lens 2 rotates around the rotary button assembly 3 as an axis.

[0030] Specifically, an I-shaped movable groove 121 is provided in the middle of the hanging groove 12, positioning holes 122 are arranged above and below the I-shaped movable groove 121, and an insertion hole 123 is arranged through the middle of the I-shaped movable groove 121;

[0031] The rotary button assembly 3 includes a decorative cover 31, a clamping cover 32 and an elastic retaining piece 33. The elastic retaining piece 33 is pressed on the hanging groove 12. A positioning post 334 is arranged on the inner surface of the elastic retaining piece 33, and the positioning post 334 is inserted into the positioning hole 122 to realize the radial fixation of the elastic retaining piece 33 and the hanging groove 12;

[0032] The elastic retaining piece 33 is symmetrically provided with retaining tooth grooves 331. A raised hole 332 is opened in the middle of the retaining tooth grooves 331, and a deformation groove 336 is opened between the raised hole 332 and the retaining tooth grooves 331. The deformation groove 336 provides space for the deformation of the retaining tooth grooves 331. A limiting protrusion 333 is integrally and symmetrically arranged in the middle of the raised hole 332;

[0033] Fixed retaining posts 211 are integrally and symmetrically arranged on the inner side surface of the hanging ear 21. The fixed retaining posts 211 are slidably connected with the retaining tooth grooves 331 and are limited and retained when passing through the teeth of the retaining tooth grooves 331, so as to realize the relative fixation of the rotating lens 2 and the helmet body 1, and the flipping angle of the rotating lens 2 is adjusted according to different gears;

[0034] A circular hole 212 is formed in the middle of the ear hook 21, and the circular hole 212 is sleeved on the convex hole 332, so that the ear hook 21 rotates around the axes of the circular hole 212 and the convex hole 332;

[0035] An insertion card convex ring 321 is provided on the inner side surface of the card cover 32. The insertion card convex ring 321 passes through the circular hole 212 and then is inserted into the convex hole 332 and positioned by the limit convex 333, so that the card cover 32 is fixed.

[0036] The decorative cover 31 is inserted and connected to the outer side surface of the card cover 32.

[0037] Working principle: Elastic gear position pieces 33 are installed on both sides of the helmet main body 1. Then, the fixed gear columns 211 of the ear hooks 21 are inserted into the gear teeth grooves 331. The ear hooks 21 rotate clockwise. The left fixed gear column 211 slides upward clockwise from the bottom gear position, and the right fixed gear column 211 slides downward clockwise from the top gear position, and the rotating lens 2 is opened. The ear hooks 21 rotate counterclockwise. The left fixed gear column 211 slides downward counterclockwise from the top gear position, and the right fixed gear column 211 slides upward counterclockwise from the bottom gear position, and the rotating lens 2 is closed. Through the action of the double gear teeth grooves 331, the support of the rotating lens 2 is more stable when it is suspended. After the rotating lens 2 is completely closed, the negative pole 22 of the magnet and the positive pole 13 of the magnet are adsorbed, so as to limit and fix the lens.
