The guide column 110 can be configured as a stepped cylindrical structure, and one end of the guide column 110 can be fixedly installed coaxially with the bottom of the base 100 by welding or integral forming connection, which facilitates the stability of the guide column 110. The construction material of the guide column 110 can also be consistent with the base 100, which facilitates the cost saving of the control assembly. The containing cavity and the guide column 110 can ensure the movement trajectory and spatial layout of the entire control assembly, and ensure the accuracy and stability of the helmet sight locking or unlocking action.

[0053] The limiting mechanism 200 can be arranged in the accommodating cavity of the base 100, and the limiting mechanism 200 can be movably sleeved with the guide column 110 in a coaxial manner.

In this way, the user can easily rotate the knob 400 and other operations, and the external shape of the knob 400 can also be provided with a texture or structure for anti-skid and increasing the grip feeling, so as to improve the convenience and comfort of the user's operation.

[0056] The bottom of the knob 400 can be configured with a knob protrusion 410, which can abut against the limiting mechanism 200 and the connecting plate 300. By rotating the knob 400, the relative position between the knob protrusion 410 and the limiting mechanism 200 changes, and the knob protrusion 410 can drive the connecting plate 300 to rotate to the locked position or the unlocked position, thereby driving the helmet sight to the locked position or the unlocked position.

[0057] ​The user can control the position of the helmet sight by rotating the knob 400, so that the helmet sight can be switched between the locked position and the unlocked position. When the knob 400 is rotated to different positions, the linkage action of the connecting plate 300 and the limiting mechanism 200 can make the helmet sight stably stay in the corresponding locked position or unlocked position, so that the user can quickly and accurately adjust the position of the helmet sight according to the actual demand, thereby ensuring the safety and convenience of the helmet use.

The bottom end of the spring 210 can abut against the inner bottom wall of the accommodating cavity, so that the base 100 provides support for the spring 210, and the spring 210 can be easily repaired and replaced later. The structural material of the spring 210 can be stainless steel, which has high strength and corrosion resistance, so that the spring 210 can maintain stable working state in harsh environment and greatly improve the service life of the spring 210.

[0061] The limiting plate 220 can be constructed as an irregular cylindrical structure with an inner cavity. The cross-sectional area of the limiting plate 220 should match the accommodating cavity, so that the limiting plate 220 can be stably installed inside the accommodating cavity. The limiting plate 220 can be movably sleeved outside the guide column 110 by coaxial sleeve connection. One side of the limiting plate 220 can abut against the top end of the spring 210. In this way, under the elastic force of the spring 210, the limiting plate 220 can be away from the base 100. When the user rotates the knob 400, the knob protrusion 410 can press down the limiting plate 220 under the action of the spring 210, so that the unlocking of the connecting plate 300 can be completed, and the unlocking of the helmet sight glass can be completed.
