References herein to "left", "right", etc., are defined in terms of those skilled in the art's customary viewing angles for helmets in the deployed state.

Fig. 1 to 5 show a helmet of the present embodiment. As shown in fig. 1 to 5, the helmet includes a helmet body 1, a visor 2, and connectors 21 connected to left and right ends of the visor 2, respectively. The helmet further comprises an adjusting mechanism 3 for adjusting the position of the visor 2, and each of the connectors 21 is movably connected to the left and right sides of the helmet body 1 through one of the adjusting mechanisms 3, respectively.

As shown in fig. 3 and 4, each adjustment mechanism 3 includes a first tooth 31 and a second tooth 32, respectively, which can mesh with each other. The first tooth 31 is disposed on the helmet body 1 and extends outward from the helmet body 1, and the second tooth 32 is disposed on the connecting member 21 and extends inward from the connecting member 21. The terms of orientation "inner" and "outer" as referred to herein are defined with reference to the center of the helmet body, with the side closer to the center of the helmet body being the inner side and vice versa. The adjustment mechanism 3 further comprises a resilient member 33 for urging the second teeth 32 inwardly. The adjusting mechanism 3 has a locking state and an adjusting state, when the adjusting mechanism 3 is in the locking state, the first tooth 31 and the second tooth 32 are engaged, and the elastic element 33 is in an initial state; when the adjusting mechanism 3 is in the adjusting state, the first tooth 31 and the second tooth 32 are released, and the elastic member 33 has an elastic deformation for urging the second tooth 32 to move inward to engage with the first tooth 31.

The helmet body 1 is provided with a mounting post 34, and the mounting post 34 extends outwards from the helmet body 1. In this embodiment, the left side of the helmet main body 1 is provided with a mounting column 34, and the mounting column 34 extends horizontally to the left from the outer side surface of the helmet main body 1; the right side of the helmet main body 1 is provided with a mounting column 34, and the mounting column 34 horizontally extends to the right from the outer side surface of the helmet main body; the center line of the left mounting post 34 coincides with the center line of the right mounting post 34, and the center line is the rotation axis of the goggles 2. The connecting pieces 21 on the two sides are respectively sleeved on the mounting posts 34 on the corresponding sides, and the connecting pieces 21 are allowed to rotate around the mounting posts 34 and can also slightly move for a short distance along the mounting posts 34, so that the second teeth 32 and the first teeth 31 can be allowed to be mutually loosened or meshed.

The left and right sides of the helmet main body 1 are respectively and fixedly provided with a toothholder 30, the toothholder 30 is sleeved on the mounting column 34 and is positioned between the helmet main body 1 and the connecting piece 21, the first tooth 31 is formed on one side of the toothholder 30 facing the connecting piece 21, and the second tooth 32 is formed on one side of the connecting piece 21 facing the helmet main body 1. A first plurality of teeth 31 are disposed on the carrier 30 around the mounting post 34 and a second plurality of teeth 32 are disposed on the link 21 around the mounting post 34. It is also noted that: unlike the prior art, in which the first tooth 31 is formed on the outer end surface of the tooth holder 30 instead of the circumferential surface, the second tooth 32 can slightly move inside and outside the mounting post 34 to engage or disengage with the first tooth 31.
