One end of the spring 157 is sleeved on the positioning column 156 and abuts against the lens switch 150, and the other end abuts against the lens base 130. When the second cavity wall 154 is embedded in the notch 148, the spring 157 may be in a normal state without elastic force, or may have a certain elastic force to press the lens switch 150 against the state. When the lens switch 150 is rotated and the second chamber wall 154 is away from the notch 148, the spring 157 is compressed to generate an elastic force or further compressed to generate a larger elastic force, and the elastic force can help the lens switch 150 to reset, so that the second chamber wall 154 is kept in a state of being embedded in the notch 148.
The use of the present invention is to mount the lens locking mechanism 120 to the helmet body. When the goggles 101 are attached, the switch lever 151 is manually or by a tool pulled to hold the switch lever in the unlocked state, the attachment post 102 on the goggles 101 is inserted into the lumen 146, and the fourth blocking wall 103 moves axially along the lumen 146 from within the notch 148 until it passes over the first blocking wall 149. Releasing switch lever 151, spring 157 rotates lens switch 150 to the locked state. At this time, the fourth blocking wall 103 is located in the lumen 146, and the first blocking wall 149 and the second blocking wall 155 axially block the lumen 146 and block the fourth blocking wall 103 from exiting from the lumen 146. The goggles 101 cover the accommodating groove 131, and the limit posts 104 are transversely arranged on the guide rails 133 and can move along the guide rails 133. The attachment post 102 is rotatable within the lumen 146 to allow the visor 101 to rotate. This allows the visor 101 to be connected to the lens locking mechanism 120, and the visor 101 can be rotatably mounted to the helmet body.
When the angle of the goggles 101 needs to be adjusted, as shown in fig. 12 to 14, the lens locking mechanism 120 is in a locked state in the state shown in fig. 12. The goggles 101 are rotated anticlockwise, and the limit posts 104 of the goggles 101 can move on the guide rails 133 and can be kept at corresponding positions, as shown in fig. 13, because the guide rails 133 are formed by a plurality of grooves, the limit posts 104 can be kept at the positions when embedded in the grooves, and can continue to move along the guide rails 133 when being acted by external force until anticlockwise rotating at the top points of the guide rails 133. As shown in fig. 14, when the goggles 101 are rotated to the maximum angle, the switch lever 151 is exposed. At this time, the lens locking mechanism 120 can be changed into an unlocked state by the fluctuation switch lever 151, the connecting post 102 can be withdrawn from the lumen 146 by pulling the lens outwards, and the goggles 101 can be detached by releasing the connection between the goggles 101 and the lens locking mechanism 120.
