DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figures 1 to 6The utility model provides a technical solution: an assembled filter holder, including a filter holder installed on a lens A, including a sleeve ring 11 sleeved on the outside of the lens A, a sleeve 12 sleeved on the outside of one end of the sleeve ring 11, a filter support plate 13 fitted and connected to one end of the sleeve 12, and a filter lens 14 installed at the center of the filter support plate 13. The sleeve ring 11 is sleeved on the outside of the lens A and is kept stable by the friction resistance between the sleeve ring 11 and the outer surface of the lens A. However, when removing the filter support plate 13, there is no need to continuously remove the sleeve ring 11. The sleeve 12 and the filter support plate 13 are manufactured by conventional methods (such as injection molding). The sleeve 12 is sleeved on the outside of one end of the sleeve ring 11. The sleeve 12 does not directly contact the lens A. The removal of the sleeve 12 and the filter support plate 13 will not be affected by the lens A. The integrated sleeve 12 and the filter support plate 13 are assembled with the sleeve ring 11; the limited component includes a sliding sleeve on the outside of the sleeve ring 11. The pulling ring 21, a block 23 of which one end is connected to the inner surface of one end of the sleeve ring 11 by a pin, and a first pull rope 22 that slides through the sleeve ring 11 and is connected to the block 23 and the pulling ring 21 at both ends. The pulling ring 21 is limited by the "T"-shaped end of the sleeve ring 11. When the pulling ring 21 is pulled to one side, the pulling ring 21 pulls the first pull rope 22, and the first pull rope 22 drives the block 23 to rotate, and the block 23 leaves the sleeve 12, so that the sleeve 12 and the sleeve ring 11 can be separated. When assembling the filter support plate 13, a return spring 111 is provided on the surface of the sleeve ring 11 near the block 23. When the first pull rope 22 pulls the block 23 to rotate, the block 23 squeezes the return spring 111. The return spring 111 generates an elastic force to reset the block 23. When reinstalling the filter support plate 13, the sleeve 12 is placed on the outside of one end of the sleeve ring 11, and the pull ring 21 is released. Under the action of the return spring 111, the block 23 presses against the sleeve 12, which can conveniently limit the sleeve 12 in position.

[0029] In this embodiment, the end of the connecting ring 11 away from the sleeve 12 is a "T"-shaped structure, and the outer surface of the "T"-shaped connecting ring 11 is provided with a first ring groove for the pulling ring 21 to move, which is conducive to the movement of the pulling ring 21, so that the first pull rope 22 drives the clamping block 23 to rotate. The inner surface of the sleeve 12 is provided with a second ring groove that cooperates with one end of the clamping block 23. One end of the clamping block 23 is located in the second ring groove of the sleeve 12. The clamping block 23 is against the sleeve 12, which can conveniently limit the sleeve 12.

[0030] In this embodiment, an adjustment component is provided on the outer surface of the sleeve ring 11, and the adjustment component includes a fixed cylinder 31 sleeved on the outside of the sleeve ring 11 and a spiral cylinder 32 screwed together with the fixed cylinder 31 by a thread. The fixed cylinder 31 and the sleeve ring 11 are firmly fixed by friction resistance. A symmetrically distributed "L"-shaped limiting rod 321 is provided on the side of the spiral cylinder 32. The end of the limiting rod 321 away from the spiral cylinder 32 is spherical. When the spiral cylinder 32 spirals and moves along the axial direction of the fixed cylinder 31, the limiting rod 321 drives the movable ring 35 to move, thereby changing the position of the movable ring 35.

[0031] The second pull rope 33 is connected to the outer surface of the filter support plate 13 at one end, and the sun visor 34 is rotatably connected to the surface of the filter support plate 13. The sun visor 34 has the effect of blocking sunlight and adjusting light. The other end of the second pull rope 33 is connected to the outer surface of the sun visor 34. The outer surface of the movable ring 35 is provided with a third ring groove that cooperates with the limiting rod 321. One end of the limiting rod 321 is embedded in the third ring groove. When the limiting rod 321 drives the movable ring 35 to move, the second pull rope 33 pulls the sun visor 34 to flip, which can change the sunshade angle and range. The inner surface of the movable ring 35 is provided with a protrusion 351, and the outer surface of one end of the fixed cylinder 31 is provided with a groove for the sliding of the protrusion 351. The protrusion 351 is limited, so that the movable ring 35 does not deflect during the movement, thereby ensuring that it slides linearly in a predetermined direction.

[0032] In this embodiment, a guide rod 131 for the second pull rope 33 to pass around is provided on the outer surface of the filter support plate 13 . The guide rod 131 serves to change the direction of the second pull rope 33 .

[0033] Steps for assembling the filter support plate 13:

[0034] When removing the filter support plate 13, pull the pull ring 21 to one side, the pull ring 21 pulls the first pull rope 22, and the first pull rope 22 drives the clamping block 23 to rotate;

[0035] At this time, the clamping block 23 leaves the sleeve 12, so that the sleeve 12 and the sleeve ring 11 can be separated, making it easier to assemble the filter support plate 13;

[0036] At the same time, the block 23 presses the return spring 111, and the return spring 111 generates an elastic force to return the block 23 to its original position.

[0037] When reinstalling the filter support plate 13, the sleeve 12 is placed on the outside of one end of the sleeve ring 11;

[0038] Release the pull ring 21, and under the elastic force of the return spring 111, the block 23 presses against the sleeve 12, which can conveniently limit the position of the sleeve 12;

[0039] To sum up: the filter support plate 13 is designed for convenient assembly and disassembly on the lens. The integrated sleeve 12 and the filter support plate 13 are assembled with the sleeve ring 11. The clamping block 23 is against the sleeve 12, which can conveniently limit the sleeve 12 and achieve the purpose of assembling the filter support plate 13. Similarly, by pulling the pull ring 21, the first pull rope 22 drives the clamping block 23 to rotate, and the clamping block 23 leaves the sleeve 12, which can realize the separation of the sleeve 12 and the sleeve ring 11, and the filter support plate 13 can be conveniently disassembled.

[0040] Example 2

[0041] See also Figures 1 to 7 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. In order to facilitate the disassembly and assembly of the filter lens 14 on the filter support plate 13 and the replacement of filters with the same outer diameter and different thicknesses, a clamping assembly is provided on the inner surface of the filter support plate 13. The clamping assembly includes a stabilizing ring 41 connected to the inner surface of the filter support plate 13 and a rotating ring 42 rotatably sleeved on the outer side of the stabilizing ring 41. The stabilizing ring 41 is combined with the filter support plate 13 by a conventional method (such as screwing and fixing). A connecting piece is provided inside the stabilizing ring 41 and the rotating ring 42. The connecting piece includes one end A pressing piece 43 is rotatably connected to the inside of the stabilizing ring 41 via a pin, and a connecting rod 44 at one end is rotatably connected to the inner surface of the rotating ring 42 via a pin. The connecting rod 44 passes through the stabilizing ring 41, and the connecting rod 44 and the pressing piece 43 are rotatably connected via a pin. When the rotating ring 42 rotates, the connecting rod 44 drives one end of the pressing piece 43 to rotate, thereby causing the pressing piece 43 to leave the side position of the filter lens 14, so that the filter lens 14 and the filter support plate 13 are in a loose state, and the filter lens 14 can be easily disassembled and replaced. The transmission structure of the connecting rod 44 driving the pressing piece 43 can be adjusted according to actual conditions.

[0042] In summary, the filter lens 14 and the filter support plate 13 are a combined structure. By rotating the rotating ring 42, the position of the pressing plate 43 can be adjusted, thereby loosening the filter lens 14 and the filter support plate 13, and the filter lens 14 can be easily disassembled and replaced.
