[0019] As Figures 1-2 Indicated, a helmet, including helmet main body 10, easily dismantle helmet lens holder combination structure, easily dismantle helmet lens holder combination structure includes lens holder 20 and lens 30, lens holder 20 and helmet main body 10 fixedly connected.The lens holder 20 and lens 30 are arranged in the helmet main body 10.The outward face of the lens 30 is provided with a stand 31, and the stand 31 is arranged between the lens 30 and the inner wall of the helmet main body 10, which can prevent the lens 30 and the helmet main body 10 from rubbing to cause the lens 30 to wear.

[0020] As Figures 2-5 Indicated, the both ends of the lens 30 are provided with connecting holes 32, the connecting holes 32 are provided with openings 33 and clamping lugs 34, the lens holder 20 is provided with rotating shafts 21 matched with the connecting holes 32, and the connecting holes 32 are clamped with the rotating shafts 21 through the clamping lugs 34.The lens 30 and the lens holder 20 are clamped, and the lens 30 can be disassembled manually without tools, so that the structure is simple and the assembly is convenient.

[0021] The lens holder 20 is provided with guide grooves 22, the lens 30 is provided with sliding blocks 35, and the sliding blocks 35 slide in the guide grooves 22 when the lens 30 rotates.

[0022] The lens holder 20 is provided with limiting grooves 23, the both ends of the limiting grooves 23 are provided with limiting recesses 24, the lens 30 is provided with limiting rods 36, the limiting rods 36 slide in the limiting grooves 23, and when the limiting rods 36 are clamped into the limiting recesses 24, the rotation of the lens 30 is limited.

[0023] The rotating shafts 21 are provided with bosses 25, and the connecting holes 32 are located between the bosses 25 and the lens holder 20.Because the lens 30 is injection molded, the radii of the lens 30 and the lens holder 20 are different, and by clamping the both ends of the lens 30 between the bosses 25 and the lens holder 20, the lens 30 is shaped.

[0024] The lens 30 is provided with a convenient to pull push-pull part 37. The lens holder 30 upper end is provided with a blocking strip 26. The blocking strip 26 can prevent the lens 30 from being pushed through the head when pushing the lens 30 upward.

[0025] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, simple changes and substitutions by those skilled in the art are within the protection scope of the present application.
