Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to an optical lens assembly of an optical filter which is easy to disassemble and assemble. Background Art

[0002] Filters are a type of optical element that selectively selects spectral wavelengths for transmission, reflection, cutoff, and attenuation. Optical filters are formed by coating one or more layers of dielectric or metal films on optical elements or independent substrates to change the characteristics of light wave transmission. The characteristics of light waves produced during transmission in these thin films, such as transmission, absorption, scattering, reflection, polarization, phase change, etc., are used to design and manufacture various filter products to achieve scientific and engineering application purposes.

[0003] For example, the patent with publication number CN214384622U discloses an optical lens assembly with a replaceable optical filter, including a lens fixing seat, a filter support frame movably connected inside the lens fixing seat, an optical filter overlapped at one end of the filter support frame, a filter positioning plate overlapped at one end of the optical filter, a slot hole matched with the filter support frame is formed inside the lens fixing seat, and a positioning slot matched with the filter positioning plate is formed at the top of the lens fixing seat.

[0004] Through the above arrangement, the prior art places the optical filter on the filter support frame, so that the filter support frame supports the optical filter, and through the action of gravity, the filter support frame drives the optical filter to move to the middle of the lens fixing seat, so that the filter positioning plate and the top surface of the lens fixing seat are parallel, and the optical filter is pressed by the filter positioning plate, so that the optical filter can be effectively disassembled and assembled, avoiding the disassembly and assembly of screws, and the structure is simple, which is convenient for rapid replacement and maintenance of the optical filter. However, the optical lens assembly with replaceable optical filters in the prior art solution has the following defects during operation:

[0005] In the above technical solution, when the optical filter needs to be replaced, the filter positioning plate is rotated to release the pressure of the filter positioning plate on the optical filter, so that the optical filter is displaced upward along with the filter support frame, and the optical filter is moved out of the lens fixing seat to replace the optical filter. The optical filter can be replaced quickly. However, when the device reinstalls the optical filter, it is necessary to rotate the filter positioning plates at both ends at the same time to install the two ends of the optical filter between the support seats, and the filter positioning plate also needs to be perpendicular to the top of the lens fixing seat, otherwise the optical filter will not be able to be installed, resulting in a long installation time and affecting work efficiency. Utility Model Content

[0006] The utility model aims to provide an optical lens assembly with an optical filter that is easy to disassemble and assemble, and is mainly used to solve the technical problem of the complicated replacement of optical filters in the prior art.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] An optical lens assembly for an optical filter that is easy to disassemble and assemble comprises a lens fixing seat, a ring block is fixedly connected to the top of the lens fixing seat, a first arc groove is provided on the side wall of the ring block, a fixed pressure ring is rotatably connected to the top of the ring block, a second arc groove is provided on the side wall of the fixed pressure ring, the first arc groove and the second arc groove match each other, the optical filter is movably connected to the inner side wall of the lens fixing seat, a plurality of mounting grooves are provided on the inner side wall of the lens fixing seat, a lifting plate is slidably connected to the inner side wall of the mounting groove, a rotating component is provided on the top of the lifting plate, and an engaging component is provided on the side wall in the mounting groove.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: The optical lens assembly structure of the optical filter that is easy to disassemble and assemble in the utility model is similar to the optical lens assembly structure of the existing replaceable optical filter. For example, the patent with publication number CN214384622U discloses an optical lens assembly with replaceable optical filter. The main improvement of the utility model is that when the device needs to install the optical filter, the fixed pressure ring is removed from the upper end of the lens fixing seat by rotating the fixed pressure ring. After the fixed pressure ring is removed, the engaging component is adjusted. When the engaging component works, it drives the rotating component to work in the opposite direction, so that the lifting plate slides upward on the inner side wall of the installation groove, and the lifting plate is used to drive the old optical filter to move upward, so that the old optical filter is taken out for replacement of the new optical filter. The new optical filter is placed on the top of the lifting plate, and then the optical filter is pressed. In this process, the rotating component works, and the rotating group drives the engaging component to work while working. When the optical filter moves to the installation position, the engaging component limits the optical filter, thereby completing the replacement of the optical filter.

[0011] 2. Beneficial effects:

[0012] The prior art solves the technical problem of setting up replaceable optical filters. However, it is cumbersome to replace optical filters in the existing optical lens assembly. The present solution solves the technical problem of quickly replacing the optical filter by setting up a lifting plate. During installation, a new optical filter is placed on the top of the lifting plate, and then the optical filter is pressed to slide the lifting plate downward along the inner wall of the installation groove. During this process, the rotating assembly works, and the rotating group drives the engaging assembly to work at the same time. When the optical filter moves to the installation position, the engaging assembly limits the optical filter, thereby completing the technical problem of quickly replacing the optical filter.

[0013] Preferably, the rotating assembly includes a mounting hole that passes through the top of the lifting plate, the inner side wall of the mounting hole is slidably connected with a rotating rod, the bottom of the rotating rod is rotatably connected to the bottom of the mounting groove, the outer side wall of the rotating rod is provided with an arc-shaped sliding groove, the bottom of the lifting plate is fixedly connected with a mounting seat, the inner side wall of the mounting seat is fixedly connected with a connecting rod, the end of the connecting rod away from the mounting seat is fixedly connected with a sliding block, and the sliding block is slidably connected to the inner side wall of the arc-shaped sliding groove. When a new optical filter needs to be installed, it is only necessary to place the optical filter on the top of the lifting plate, and then press the optical filter to make the lifting plate slide downward along the inner side wall of the mounting groove. During this process, the lifting plate drives the mounting seat and the connecting rod to move downward at the same time, and the sliding block slides along the inner side wall of the arc-shaped sliding groove. Under the mutual cooperation of the sliding block and the arc-shaped sliding groove, the rotating rod rotates along the inner side wall of the mounting hole until the optical filter moves to the installation position, and then the meshing assembly is driven to work during the rotation of the rotating rod, thereby limiting the optical filter, thereby quickly completing the installation of the optical filter without fixing them one by one.

[0014] Preferably: the meshing assembly includes a rectangular slide groove opened on the inner side wall of the mounting groove, the inner side wall of the rectangular slide groove is slidably connected with a toothed plate, the top of the rotating rod is fixedly connected with a gear adapted to the toothed plate, the gear and the toothed plate are meshed with each other, when the rotating rod rotates, the rotating rod drives the gear to rotate, and the gear drives the toothed plate to move, so that the toothed plate slides outward along the inner side wall of the rectangular slide groove, thereby fixing the optical filter inside the lens fixing seat through the toothed plate, thereby completing the rapid replacement of the optical filter.

[0015] Preferably: a spring is sleeved on the outer wall of the rotating rod, the upper end of the spring is fixedly connected to the bottom of the lifting plate, and the other end of the spring is fixedly connected to the bottom of the mounting groove; when the lifting plate moves downward, the spring is compressed, and when the tooth plate is clamped on the top of the optical filter, the pressing on the optical filter is stopped, and the lifting plate is pushed by the compressed spring, so that the optical filter is clamped between the lifting plate and the tooth plate, thereby preventing the optical filter from loosening.

[0016] Preferably: a plurality of L-shaped pressing blocks are fixedly connected to the inner side wall of the fixed pressing ring, and the end of the L-shaped pressing block contacts the top of the optical filter. When a new optical filter needs to be fixed, it is only necessary to place the optical filter on the top of the lifting plate, and then clamp the fixed pressing ring and the annular block. During the clamping process, the L-shaped pressing block contacts the lifting plate, thereby giving the lifting plate a downward force, completing the automatic and quick clamping work, and the operation is relatively simple.

[0017] Preferably, the length of the lifting plate is much larger than the bottom of the mounting groove, and the end of the lifting plate extends to the inside of the lens fixing seat, so that the optical filter is placed on the top of the lifting plate, and then the lifting plate moves downward by pressing the optical filter without affecting the rotation of the shaft.

[0018] Preferably: the rotating rod and the mounting hole can rotate, the length of the tooth plate is greater than the moving range of the lifting plate, the rotating rod and the mounting hole can rotate, so that the rotating rod can rotate on the inner wall of the mounting hole, and the tooth plate is driven by the gear, thereby limiting the optical filter.

When the optical filter 2 needs to be installed, the optical filter 2 is placed on the top of the lifting plate 10, and then the fixing pressure ring 1 is connected to the fixing pressure ring 1. The annular block 4 is clamped, and during the clamping process, the L-shaped pressure block 5 contacts the lifting plate 10, thereby giving the lifting plate 10 a downward force, so that the lifting plate 10 slides downward along the inner wall of the mounting groove 11. During this process, the spring 19 is compressed. During the descent of the lifting plate 10, the lifting plate 10 drives the mounting seat 15 and the connecting rod 16 to move downward at the same time, and the slider 17 slides along the inner wall of the arc-shaped slide groove 9. Under the mutual cooperation of the slider 17 and the arc-shaped slide groove 9, the rotating rod 8 rotates along the inner wall of the mounting hole 18. The side wall in the mounting groove 11 is provided with an engaging component, and the engaging component The component includes a rectangular slide groove 12 opened on the inner wall of the installation groove 11, and the inner wall of the rectangular slide groove 12 is slidably connected with a tooth plate 13. The top of the rotating rod 8 is fixedly connected with a gear 14 adapted to the tooth plate 13, and the gear 14 and the tooth plate 13 are meshed with each other. When the rotating rod 8 rotates, the rotating rod 8 drives the gear 14 to rotate, and the gear 14 drives the tooth plate 13 to move, so that the tooth plate 13 slides outward along the inner wall of the rectangular slide groove 12, so that the optical filter 2 is clamped between the lifting plate 10 and the tooth plate 13 to prevent the optical filter 2 from loosening, thereby completing the installation of the optical filter.

[0027] From the above, it can be seen that the specific implementation of the utility model is as follows:

Under the action of the compression spring 19, the lifting plate 10 drives the optical filter 2 to move upward. When the lifting plate 10 rises, the tooth plate 13 shrinks to the inside of the rectangular slide groove 12, so that the optical filter 2 is not restricted and can be easily taken out.
