Description

Technical Field

[0001] The utility model belongs to the technical field of optical lenses, and in particular relates to a dust-proof linkage protective cover for an optical lens. Background Art

[0002] In the field of photography, as people's demands for visual experience continue to rise, traditional fixed-angle shooting methods are no longer able to meet diverse shooting needs. Especially in scenes such as tourism, architecture, landscapes, and sports, capturing all-around, multi-angle images has become a goal for photographers. Therefore, the panoramic rotating shooting system has emerged. Through a series of sophisticated mechanical and optical designs, it achieves continuous horizontal rotation of the lens, thereby capturing a wider and more three-dimensional image.

[0003] For panoramic shots, special angles, or certain creative photography fields, the lens needs to be able to rotate 180 degrees horizontally to capture a wider scene or capture shots from a unique angle. In existing technology, the front imaging lens can rotate 180 degrees through the coordination of multiple gears and prisms. However, the gears and prisms are exposed and unprotected during 180-degree rotation, and using a fixed housing would limit the rotation angle. Utility Model Content

[0026] like Figure 1-3As shown, a linked dustproof protective cover for an optical lens includes a lens stacked protective cover, a left extendable stacked protective cover group, and a right extendable stacked protective cover group. The lens stacked protective cover is mounted outside the left and right extendable stacked protective cover groups. The left extendable stacked protective cover group is composed of a plurality of first stacked protective covers 1 stacked together, while the right extendable stacked protective cover group is composed of a plurality of second stacked protective covers 2 stacked together. When the lens stacked protective cover is rotated to the left, the left extendable stacked protective cover retracts, the plurality of first stacked protective covers 1 stacked together, the right extendable stacked protective cover group expands, and the plurality of second stacked protective covers 2 expand to form an arc-shaped protective cover structure. When the lens stacked protective cover is rotated to the right, the right extendable stacked protective cover retracts, the plurality of second stacked protective covers 2 stacked together, the left extendable stacked protective cover group expands, and the plurality of first stacked protective covers 1 expand to form an arc-shaped protective cover structure.

[0027] Combine Figure 4 The lens stacked protective cover includes an outer cover plate 3, a lens through hole 4 is provided in the middle of the outer cover plate 3, a lens protective plate 5 and a lens linkage protective plate 6 are respectively provided on both sides of the outer cover plate 3, and a first axial hole 7 is provided at the bottom of the lens linkage protective plate 6. The lens through hole 4 is used to extend the optical lens. When the angle of the optical lens needs to be adjusted, it is only necessary to adjust the angle of the lens stacked protective cover to drive the optical lens to rotate and adjust the corresponding angle. The lens protective plate 5 plays a side protection role, and the lens linkage protective plate 6 is connected to the corresponding shaft through the first axial hole 7 to achieve the rotation effect. At the same time, a first active raised linkage part 20 is provided on the inner side of the lens protective plate 5, and a second active raised linkage part 21 is provided on the inner side of the lens linkage protective plate 6. The two active raised linkage parts are respectively used to cooperate with the adjacent first stacked protective cover 1 and the second stacked protective cover 2, and the corresponding stacked protective cover layers are pulled to expand and contract through the two active raised linkage parts.

[0028] Combine Figure 5The sizes of the multiple first-layered protective covers 1 gradually increase. Specifically, the first-layered protective covers 1 include a first cover plate 8, with a first protective plate 9 and a first linkage protective plate 10 provided on either side of the first cover plate 8. After deployment, the closer the first-layered protective covers 1 are to the lens-mounted protective cover, the longer the first cover plate 8 is, while the farther the first-layered protective covers 1 are from the lens-mounted protective cover, the shorter the first-layered protective covers 1 are. Furthermore, the closer the first linkage protective plates 10 and the first protective plates 9 are to the lens-mounted protective cover, the longer their lengths should be, while the farther the first linkage protective plates 10 and the first protective plates 9 are from the lens-mounted protective cover, the shorter their lengths should be. In this way, the multiple first-layered protective covers 1 can be retracted together when retracted. A first inner protruding linkage portion 11 is provided on the inner side of the first linkage protective plate 10, a first outer protruding linkage portion 12 is provided on the outer side of the first linkage protective plate 10, and a second axial hole 13 is provided on the bottom of the first linkage protective plate 10. The second axial hole 13 is also convenient for the first linkage protective plate 10 to be rotatably connected with the corresponding shaft to realize the first linkage protective plate 10. The first inner protruding linkage portion 11 on the inner side of the first linkage protective plate 10 is used to drive the adjacent inner first stacked protective cover 1 to unfold. When rotating, the first inner protruding linkage portion 11 on the inner side of the first linkage protective plate 10 contacts the first outer protruding linkage portion 12 on the outer side of the first linkage protective plate 10 on the adjacent inner first stacked protective cover 1, thereby achieving the effect of pulling it to rotate and unfold, and the remaining first stacked protective covers 1 can be unfolded in sequence according to the above method.

[0029] Combine Figure 6 The sizes of the first stacked protective covers 1 also gradually increase. The second stacked protective cover 2 includes a second cover plate 14, with second protective plates 15 and second linkage protective plates 16 respectively located on either side of the second cover plate 14. The structure of the second stacked protective cover 2 is identical to that of the first stacked protective cover 1. The only difference is that the second protective plates 15 and second linkage protective plates 16 on either side of the second cover plate 14 are positioned opposite to the first protective plates 9 and first linkage protective plates 10 on either side of the first cover plate 8. The second linkage protective plates 16 are pivotally connected to the other side of the entire assembly to avoid conflict with the first linkage protective plates 10 during rotation.

[0030] A second inner protruding linkage portion 17 is provided on the inner side of the second linkage protective plate 16, a second outer protruding linkage portion 18 is provided on the outer side of the second linkage protective plate 16, and a third axial hole 19 is provided on the bottom of the second linkage protective plate 16. The functions of the corresponding protruding linkage portion and the third axial hole 19 refer to the previous paragraph. The first axial hole 7, the second axial hole 13 and the third axial hole 19 are coaxially arranged.

[0031] The first outer raised linkage part 12 is a first outer raised strip linkage block arranged on the outer side of the first linkage protective plate 10, the first inner raised strip linkage block 11 is a first inner raised strip linkage block arranged on the inner side of the first linkage protective plate 10 away from the first outer raised strip linkage block, the structure of the second outer raised linkage part 18 is the same as that of the first outer raised linkage part 12, and the structure of the second inner raised linkage part 17 is the same as that of the first inner raised linkage part 11. In this embodiment, the lens linkage protective plate 6 is rotatably arranged on the same side as several second linkage protective plates 16. When the lens stacked protective cover is driven to rotate counterclockwise, the second active protrusion linkage portion 21 on the lens linkage protective plate 6 cooperates with the second outer protrusion linkage portion 18 on the adjacent second linkage protective plate 16 to drive the adjacent second stacked protective cover 2 to rotate. Then, the second linkage protective plate 16 then drives the adjacent second stacked protective cover 2 to rotate through the second inner protrusion linkage portion 17 thereon in cooperation with the second outer protrusion linkage portion 18 on the adjacent second linkage protective plate 16. The remaining second stacked protective covers 2 are similarly driven, thereby realizing the deployment protection of the right-extending stacked protective cover group. The principle of deployment of the left-extending stacked protective cover group is the same. The first active protrusion linkage portion 20 and the second active protrusion linkage portion 21 can be strips, triangles, squares, circles, etc., as long as they can be protruded to achieve the pushing effect.

[0032] The left and right extended laminated protective cover assemblies are internally provided with a rotating bracket, which houses the lens and transmission components such as gears. The rotating bracket includes a first curved plate 22 and a second curved plate 23, which are connected at their bottoms. A first rotating shaft is provided on the side of the first curved plate 22, and a second rotating shaft is provided on the side of the second curved plate 23. The first rotating shaft is used to rotatably connect with the lens linkage protective plate 6 and the plurality of second linkage protective plates 16, while the second rotating shaft is used to rotatably connect with the plurality of first linkage protective plates 10.

[0033] The bottoms of the first protective plate 9 and the second protective plate 15 are both provided with arc grooves 24, and the bottoms of the first linkage protective plate 10 and the second linkage protective plate 16 are both circular structures. The first protective plate 9 is located on the same side as the second linkage protective plate 16, and the second protective plate 15 is located on the same side as the first linkage protective plate 10. Such a structure can avoid the two relative influences during rotation.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
