Technical Field

[0001] The invention relates to the technical field of optical lenses, and in particular to an anti-glare optical lens. Background Art

[0002] An optical lens is an optical element made of transparent material that can focus or disperse light.

[0016] The working principle and beneficial effects of the present invention are:

[0017] 1.

Compared with directly realizing the shading function through the shading assembly, by first performing partial shading, the glare problem can be more accurately located and solved, avoiding unnecessary all-round shading that affects the integrity of the field of vision.

[0019] 3. By providing the rubber bushing, inner ring and support assembly, when the support assembly is pulled forward, the docking hole in the first rubber belt can be tightened, so that the first rubber belt moves to the left relative to the second rubber belt, and then the clamping ring presses the rotatable inner ring in the rubber bushing, so that the optical lens can remain fixed after leveling. After loosening the clamping ring, the inner ring and the lens body can be removed from the rubber bushing, thereby realizing the function of convenient removal and leveling of the lens.

[0020] 4. By setting four groups of first ball axes and second ball axes distributed at equal angles, when the third connecting ring moves, the third connecting ring and the first connecting ring always remain parallel, and the third connecting ring can use its own offset relative to the position of the first connecting ring to make targeted adjustments to the shading position, and make the third connecting ring gradually approach the shading assembly, so as to better realize the function of multi-stage shading adjustment.

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figure 1-Figure 9 As shown, the present embodiment proposes an anti-glare optical lens, including a rubber bushing 1, a connecting groove 2 is provided on the rubber bushing 1, a clamping ring 17 is installed in the connecting groove 2, the first and second rubber belts 18 and 19 are connected to the clamping ring 17 at both ends, the first and second rubber belts 18 and 19 are provided with docking holes 20, a supporting assembly 21 is installed in the docking hole 20, the supporting assembly 21 can tighten the inner wall of the docking hole 20 on the first rubber belt 18, so that the supporting assembly 21 can tighten the clamping ring 17, and the inner ring 4 is fitted inside the rubber bushing 1. The ring 4 is connected with a bracket 3, and the top of the bracket 3 is connected with a lens body 5. The clamping ring 17 in the clamping state can clamp the inner ring 4 after the inner ring 4 in the rubber bushing 1 is installed, so that the angle of the lens body 5 remains fixed after leveling, and after the clamping ring 17 is relaxed, the inner ring 4 and the lens body 5 can be removed from the rubber bushing 1. The outer side of the lens body 5 is fixedly connected with a first connecting ring 6, and a shading component 8 is arranged on the outer side of the first connecting ring 6. A support ring 9 is connected below the shading component 8, and a connecting component 7 (combined with Figure 1 , Figure 2 and Figure 7It can be seen that the third connecting ring 22 is connected to the bottom of the connection component 7. When the device is in use, the third connecting ring 22 can be manually adjusted to change the position of the third connecting ring 22, so as to adjust the position of the third connecting ring 22 used for shading around the lens body 5 in a targeted manner according to the position of the glare, thereby ensuring the shading effect of the device. And when the light is too strong, the device can also use the third connecting ring 22 to resist the support ring 9, so that the support ring 9 pushes the shading component 8 to achieve a full range of shading function. Compared with conventional direct shading, the device can first perform partial shading according to the glare position before shading. When the partial shading cannot achieve the anti-glare function, it will perform full range of shading. The partial shading can ensure that the lens retains more field of view when in use.

[0035] Example 2

[0036] like Figure 1-Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an anti-glare optical lens.

[0037] In this embodiment, the connecting component 7 includes a first ball shaft 701 rotatably installed around the first connecting ring 6, a connecting rod 702 is fixedly connected to the bottom of the first ball shaft 701, and a second ball shaft 703 is fixedly connected to the bottom of the connecting rod 702. A cut surface 704 is provided on the first ball shaft 701 and the second ball shaft 703, and the second ball shaft 703 and the third connecting ring 22 are rotatably connected. The first ball shaft 701 and the second ball shaft 703 on the connecting component 7 can rotate as the position of the third connecting ring 22 changes, and keep the third connecting ring 22 always parallel to the first connecting ring 6, so as to achieve a progressive shading effect later. The distance between the third connecting ring 22 and the first connecting ring 6 can be understood later based on the inclination angle of the cut surface 704.

[0038] In this embodiment, the first ball shaft 701, the connecting rod 702 and the second ball shaft 703 are integrally formed, and the first ball shaft 701 is evenly distributed along the circumference of the first connecting ring 6. The upper and lower sides of the first ball shaft 701 are both protruding on the first connecting ring 6. The protruding first ball shaft 701 cooperates with the connecting rod 702 to ensure that the second ball shaft 703 can rotate within a certain range and keep the first connecting ring 6 always level.

[0039] In this embodiment, the shading assembly 8 includes a first shading cover 801 which is slidably fixedly connected to the outer side of the first connecting ring 6, a second shading cover 802 is slidably installed on the outer side of the first shading cover 801, a third shading cover 803 is slidably installed on the outer side of the second shading cover 802, a second connecting ring 804 is fixedly connected to the bottom of the third shading cover 803, the second connecting ring 804 and the support ring 9 are fixedly connected, the third shading cover 803 can slide on the second shading cover 802, and the second shading cover 802 can slide on the first shading cover 801, so that the device can adjust the shading range.

[0040] In this embodiment, the third light shield 803 is fixedly connected to the first slider 11, the second light shield 802 is provided with a first movable groove 12 for the first slider 11 to move, the second light shield 802 is fixedly connected to the second slider 14, the first light shield 801 is provided with a second movable groove 13 for the second slider 14 to move, the second slider 14 and the first slider 11 cooperate with the first movable groove 12 and the second movable groove 13 to prevent the second light shield 802 and the third light shield 803 from detaching from the device.

[0041] In the present embodiment, the first light shield 801, the second light shield 802, the third light shield 803, the first slider 11 and the second slider 14 are all made of rubber. The bottom of the first light shield 801 is provided with a first through hole 15 which is interconnected with the second movable groove 13. The bottom of the second light shield 802 is provided with a second through hole 16 which is interconnected with the first movable groove 12. The first slider 11 and the second slider 14 made of rubber can compress the air in the first movable groove 12 and the second movable groove 13 during the sliding process, so as to subsequently reset the second light shield 802 and the third light shield 803, thereby enhancing the stability of the device during operation.

[0042] In this embodiment, a notch 10 is provided on the support ring 9, and the position and number of the notch 10 correspond one-to-one to the position and number of the connecting components 7. The lower surface of the support ring 9 is parallel to the upper surface of the third connecting ring 22, and the third connecting ring 22 always remains parallel to the support ring 9 when it moves. Subsequently, the support ring 9 can be pressed by the third connecting ring 22, so that all-round shading can be automatically performed after partial shading.

[0043] In this embodiment, the support assembly 21 includes a first pressure rod 2101 placed in the docking hole 20, and the first pressure rod 2101 is fixedly connected to a first fixed plate 2102 and a second pressure rod 2103, and the second pressure rod 2103 is fixedly connected to a second fixed plate 2104. When the first pressure rod 2101 moves forward, it can resist the inner wall of the docking hole 20, so as to subsequently tighten and fix the leveled lens to ensure the stability of the device during operation.

[0044] In this embodiment, the first pressure rod 2101, the first fixed plate 2102, the second pressure rod 2103 and the second fixed plate 2104 are a whole, ensuring that the device can stably realize the tightening function. The diameter of the second pressure rod 2103 increases gradually from the side close to the docking hole 20 to the side away from the docking hole 20. The second pressure rod 2103 with increasing diameter can gradually tighten the docking hole 20 when the first pressure rod 2101 moves forward, so that the rotational resistance of the lens can gradually increase during leveling until it is tightened and fixed.

[0045] In this embodiment, the diameters of the first fixed plate 2102 and the second fixed plate 2104 are both larger than the aperture of the docking hole 20, so as to prevent the first fixed plate 2102 and the second fixed plate 2104 from being separated from the docking hole 20 when adjusting their own positions. The docking holes 20 on the first rubber belt 18 and the docking holes 20 on the second rubber belt 19 are staggered. The first rubber belt 18 is suitable for moving to the left behind the second rubber belt 19 when the first pressure rod 2101 moves forward. When the first pressure rod 2101 tightens the first rubber belt 18, it can drive the first rubber belt 18 to move to the left, so that the first rubber belt 18 can maintain a tightened state.

[0046] Specifically, the present invention is an anti-glare optical lens, first, as Figure 1-Figure 6 and Fig. 9 As shown, when the device is in use, the inner ring 4 is installed into the rubber bushing 1. Since the inner wall of the rubber bushing 1 and the outer wall of the inner ring 4 fit each other, the bracket 3, the inner ring 4 and the lens body 5 can rotate in the rubber bushing 1, so as to level the lens body 5. After the leveling is completed, as shown in FIG. Figure 1 , Figure 5 and Figure 7-Figure 9 As shown, the first pressure rod 2101 is pulled forward, and the second pressure rod 2103 can tighten the inner wall of the docking hole 20 on the first rubber belt 18, so that the first rubber belt 18 moves to the left relative to the second rubber belt 19. When the second rubber belt 19 remains stationary, the first rubber belt 18 moves, which will cause the clamping ring 17 to press the rubber bushing 1 and make the rubber bushing 1 press the inner ring 4 and the lens body 5 after the angle adjustment is completed, so that the lens body 5 is fixed after the lens body 5 is leveled. The lens body 5 and the inner ring 4 can be disassembled and replaced in the opposite way of the above-mentioned clamping of the inner ring 4. Since the diameters of the first fixed plate 2102 and the second fixed plate 2104 are both larger than the aperture of the docking hole 20, the first fixed plate 2102 and the second fixed plate 2104 can be prevented from detaching from the docking hole 20 during the forward and backward movement of the first pressure rod 2101.

[0047] like Figure 1-Figure 6As shown, when the device generates glare, the position of the third connecting ring 22 can be adjusted according to the position of the glare, so that the distance between the third connecting ring 22 and the first connecting ring 6 changes, and because the connecting components 7 are evenly distributed along the circumference of the first connecting ring 6 and the third connecting ring 22, the device can move the third connecting ring 22 when working, and make the four groups of connecting rods 702 rotate synchronously through the first ball shaft 701 and the second ball shaft 703, so as to keep the third connecting ring 22 always parallel to the first connecting ring 6, and increase the shading area of ​​the third connecting ring 22 in the corresponding area of ​​the lens body 5 according to the glare position, so as to reduce the light entering. When the connection ring 22 still has glare, the third connecting ring 22 can be used to abut the support ring 9, and the support ring 9 can abut the second connecting ring 804 on the shading component 8, thereby pushing the third shading cover 803 to move. During the movement of the third shading cover 803, the second shading cover 802 can also be pushed to move on the first shading cover 801. The first slider 11 moves in the first moving groove 12, and the second moving groove 13 moves in the second slider 14. The first through hole 15 and the second through hole 16 ensure that the air pressure of the moving groove below the slider is stable, and the air pressure of the moving groove below the slider increases, which is convenient for resetting the second shading cover 802 and the third shading cover 803 outside the first shading cover 801. Therefore, when the device still has glare problems in partial shading, the shading component 8 is enabled to perform all-round shading. Compared with the conventional direct full shading, partial shading can ensure that the lens retains more field of view when in use.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
