Description

Technical Field

[0001] The utility model relates to the technical field of helmet goggles, in particular to a helmet goggles base buckle. Background Art

[0002] Helmet goggles are part of motorcycle and electric vehicle helmets. Their main function is to protect the rider's eyes from wind, sand, flying insects, branches, flying stones and other objects when riding. Goggles are generally designed to be transparent or translucent so that the rider can clearly see the road conditions ahead. At the same time, some goggles also have anti-fog, anti-scratch, UV protection and other properties to improve the rider's comfort and safety. When riding in the mountains, the rider may need to adjust the goggles upwards to better observe the uphill road conditions, and when riding in the desert, in order to prevent wind and sand from blowing directly into the eyes, the goggles may need to be adjusted downwards, so helmet goggles usually have angle adjustment.

[0003] Publication number CN204120320U is a quick-install helmet lens base assembly that can quickly disassemble and assemble the lens. However, the elastic push handle and the base are fixed by a buckle, which makes it easy to become loose during use, causing the lens to fall off due to loose fixation, seriously affecting the fixation and use of the lens, prone to safety accidents, and with few adjustment gears.

[0031] like Figure 1-Figure 7 As shown, a helmet goggles base buckle comprises:

[0032] The mirror buckle base 1 comprises a receiving groove 11, wherein a shaft hole 13 is provided in the receiving groove 11, wherein the shaft hole 13 is a long waist-shaped hole, and two second spring clamping grooves 14 are provided at both ends of the receiving groove 11 in mirror symmetry;

[0033] An elastic push handle 2 is slidably connected in the accommodating groove 11, and the sliding direction of the elastic push handle 2 is parallel to the length direction of the long waist-shaped hole. A rotating shaft 21 is fixedly connected to one side of the elastic push handle 2, and the rotating shaft 21 is slidably matched with the length direction of the rotating shaft hole 13. A positioning hole 22 is also provided on the rotating shaft 21, and a nut 23 is provided in the positioning hole 22. The elastic push handle 2 is also provided with two first spring slots 24 corresponding to the second spring slots 14, and each of the first spring slots 24 is provided with a compression spring 25, and both ends of each compression spring 25 are in contact between the first spring slot 24 and the second spring slot 14;

[0034] The gear slide groove 3 is arranged on the mirror buckle base 1, and the gear slide groove 3 includes a clamping portion 31 and a disengaging portion 32, and the clamping portion 31 and the disengaging portion 32 are fixedly connected;

[0035] The lens 4 is provided with a first fixing hole 41, and the first fixing hole 41 is concentrically provided with a first groove 42.
