[0028] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0029] like Figures 1-7 As shown, this embodiment provides a mirror mount, including a lens 1, a base 2, a mirror buckle 3, a first elastic body 4, a slider 5, and a second elastic body 6.

[0030] The lens 1 has a first locking block 11, a second locking block 12 and a third locking block 13 formed on the inward side of both ends, and a toggle block 14 is also provided at the lower end of the middle part of the lens 1.

[0031] A horizontally arranged mounting notch 21 is formed on the base 2, and a pressing notch 22 is formed below the mounting notch 21. The mounting notch 21 extends outward through the side wall of the base 2, and a first abutting block 23 and a second abutting block 24 are formed on the bottom surface of the mounting notch 21.

[0032] The mirror buckle 3 and the slider 5 are positioned horizontally within the mounting notch 21. A limiting protrusion 32 is formed on the side of the mirror buckle 3 facing the slider 5. An adaptation notch 54 is formed on the side of the slider 5 facing the mirror buckle 3. The limiting protrusion 32 is installed within the adaptation notch 54, which extends through to the second arc-shaped notch 53. The thickness of the pressing plate 31 is equal to or less than the length of the vertical portion of the second arc-shaped notch 53. A pressing plate 31 is formed below the mirror buckle 3, located within the mounting notch 21 and movable horizontally. A first clearance notch 33 is formed on the mirror buckle 3. A first abutting block 23 is formed on the bottom surface of the mounting notch 21, located within the first clearance notch 33 and with a thickness less than the first clearance notch 33. A first elastic body 4 is laterally arranged between the sidewalls of the first abutting block 23 and the first clearance notch 33. A first protrusion 4 is formed on the sidewalls of the first abutting block 23 and the first clearance notch 33 facing each other. Platform 231, the two ends of the first elastic body 4 are respectively fitted into the two first protrusions 231. In this scheme, the first elastic body 4 is a spring. Specifically, the first locking block 11 is locked between the first clearance notch 33 and the first abutment block 23. The vertical cross-section of the first locking block 11 is L-shaped. The bottom of the first clearance notch 33 near the first locking block 11 has a first locking notch 331 extending along the upper opening side of the first clearance notch 33. The horizontal part of the first locking block 11 is locked in the first locking notch 331.

[0033] Preferably, a pressing chamfer is formed on the side of the upper end of the first clearance notch 33. When installing the lens 1, the bottom surface of the first locking block 11 on the lens 1 is aligned with the pressing chamfer and pressed. Under the action of the pressing chamfer, the lens buckle 3 will move forward and then be inserted into the first clearance notch 33. Then the lens buckle 3 will be reset under the action of the first elastic body 4.

[0034] Preferably, such as Figure 3 As shown, the first abutment block 23 has an outward-facing arc surface, which is composed of multiple arc surfaces. The central arc surface 232 protrudes outward, so that when the lens 1 is flipped upward, during the flipping process, when the first locking block 11 passes through the central arc surface 232, the lens buckle 3 and the lens 1 will move outward a certain distance, so that the viewing area of ​​the lens 1 avoids the sealing strip on the helmet and prevents the viewing area from being scratched.

[0035] Preferably, such as Figure 3 As shown, a pointed protrusion is formed at the lower end of the central arc surface 232. When the first locking block 11 passes the pointed protrusion 233, it can be locked at the position of the pointed protrusion 233. At this time, the bottom of the lens is in a slightly open state, which can enhance ventilation and relieve stuffiness while being protected by the lens.

[0036] In another embodiment of the tip protrusion, the tip protrusion 233 can be set on the side of the lens buckle facing outward, and then the lens can be slightly opened by setting a corresponding protrusion block on the inside of the lens and adapting it to the tip protrusion 233.

[0037] Preferably, the bottom surface of the pressing notch 22 has a horizontally arranged guide strip, and the bottom surface of the pressing plate 31 has a guide groove adapted to the guide strip.

[0038] The slider 5 has a second clearance notch 51, and the bottom surface of the mounting notch 21 has a second abutment block 24. The second abutment block 24 is located inside the second clearance notch 51 and its lateral length is less than the lateral length of the second clearance notch 51. A second elastic body 6 is arranged laterally between the sidewalls of the second abutment block 24 and the second clearance notch 51. A second boss 241 is formed on the side of the sidewalls of the second abutment block 24 and the second clearance notch 51 facing each other. The two ends of the second elastic body 6 are respectively sleeved in the two second bosses 241. In this embodiment, the second elastic body 6 is a spring.

[0039] The first elastic body 4 and the second elastic body 6 are respectively arranged to tighten the buckle 3 and the slider 5 to the rear, thereby pulling the lens installed on the outer surface of the buckle 3 and the slider 5 to tighten to the rear, so that the lens can fit tightly with the sealing strip on the helmet and improve the sealing performance.

[0040] The slider 5 has a first arc-shaped notch 52 and a second arc-shaped notch 53. The first arc-shaped notch 52 is located above the slider 5, and the second arc-shaped notch 53 is located on the side of the slider 5 near the mirror buckle 3. The second locking block 12 is locked in the first arc-shaped notch 52. Specifically, the vertical cross-section of the second locking block 12 is L-shaped, and the vertical cross-section of the first arc-shaped notch 52 is L-shaped and matches the first locking block 11. A first insertion hole 521 is formed at one end of the upper surface of the first arc-shaped notch 52. The shape of the first insertion hole 521 is the same as the shape of the horizontal part of the second locking block 12. The third locking block 13 is locked inside the second arc-shaped notch 53. The first locking block 11, the second locking block 12 and the third locking block 13 rotate up and down around the same center. The vertical cross-section of the second arc-shaped notch 53 is L-shaped and matches the third locking block 13. When the third locking block 13 is slid to the uppermost end of the second arc-shaped notch 53, the mirror buckle 3 moves outward, causing the limiting protrusion 32 to disengage from the matching notch 54, so that the horizontal part of the third locking block 13 is disengaged from the bottom surface of the limiting protrusion 32.

[0041] Working principle: When lens 1 is installed and in the closed state, the first locking block 11, the second locking block 12, and the third locking block 13 of lens 1 are respectively located at the bottom of the first clearance notch 33, the first arc-shaped notch 52, and the second arc-shaped notch 53 (that is, the extreme position of counterclockwise movement). When disassembly is required, lens 1 is flipped upwards. The first locking block 11 moves against the side of the first abutment block 23 inside the first clearance notch 33. When the first locking block 11 passes the middle arc surface 232 of the first abutment block 23, the lens buckle 3 and lens 1 will move outwards a certain distance, so that the viewing area of ​​lens 1 avoids the dense cover on the helmet. The seal prevents scratches on the viewing area. After passing through the viewing area, the lens buckle 3 will reset, and then the lens 1 will continue to flip upward to its limit. At this time, the second locking block 12 is located at the first insertion hole 521 of the first arc-shaped notch 52. Then, push the lens 1 outward or move the pressing plate 31 on the lens buckle 3. The lens buckle 3 will move outward, so that the lateral part of the first locking block 11 will disengage from the first clearance notch 33. The lateral part of the third locking block 13 is offset from the limiting protrusion 32. Moreover, when moving the pressing plate 31 on the lens buckle 3, it will only be subjected to the elastic force of the first elastic body 4 and not the elastic force of the second elastic body 6, making it easier to remove.

[0042] In another embodiment, the bottom of the mirror buckle 3 may not have a pressing plate 31.

[0043] In another embodiment, the third card block 13 and the second arc-shaped notch 53 are not provided.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
