Description

Technical Field

[0001] The present invention relates to the field of photographic and video equipment, and particularly to a filter mounting structure. Background Art

[0002] During the process of taking photos and videos, a filter is added in front of the lens to obtain a better shooting effect. As users' requirements for shooting effects are getting higher and higher, a single filter can no longer meet the shooting needs of users, and users often need to install two or more filters in front of the lens for shooting.

[0003] Currently, there are two types of mounting structures for two filters on the market, which are respectively:

[0004] 1: The first filter is fixedly connected to the lens, and the second filter is movably connected to the first filter. The first filter cannot rotate relative to the lens, and the user can only rotate the second filter, which cannot meet the user's need to rotate the first filter.

[0005] 2: The first filter is movably connected to the lens, and the first filter can rotate relative to the lens. The second filter is movably connected to the first filter, but when the second filter rotates, it will drive the first lens to rotate, which cannot meet the user's need to independently control the rotation of the first filter or the second filter. Summary of the Invention

[0006] In order to solve the above problems, the present invention proposes a filter mounting structure that can freely rotate the filter.

[0007] The present invention is achieved through the following technical solutions:

[0008] The present invention proposes a filter mounting structure, which includes a lens connection disk and a first filter frame. The lens connection disk is provided with a rotation adjustment ring and a mounting ring. A fastening connection is formed between the mounting ring and the rotation adjustment ring. The mounting ring is provided with a limiting groove, and the first filter frame is provided with a limiting block. The first filter frame is adsorbed on the mounting ring, and the limiting block is received in the limiting groove. The rotation of the rotation adjustment ring drives the rotation of the mounting ring, and the rotation of the mounting ring drives the rotation of the first filter frame.

[0009] Furthermore, the mounting ring is further provided with a mounting portion, and the mounting portion is received in the rotation adjustment ring and is threadedly connected to the rotation adjustment ring.

[0010] Furthermore, the first filter frame is further provided with a first positioning ring, and the first positioning ring is received in the mounting ring and abuts against the mounting ring.

[0011] Further, the lens connection plate further includes a housing, and a first mounting groove is provided on the housing. The rotation adjustment ring and the mounting ring are both movably received in the first mounting groove, and the rotation adjustment ring is located between the housing and the mounting ring.

[0012] Further, at least one adjustment groove is provided on the housing, and the adjustment groove communicates with the first mounting groove, so that a part of the rotation adjustment ring is exposed from the housing.

[0013] Further, the filter mounting structure further includes a limiting plate. A second mounting groove communicating with the first mounting groove is also provided on the housing. The limiting plate is partially received in the second mounting groove and is movably connected to the housing. By rotating the limiting plate, the limiting plate abuts against the rotation adjustment ring to limit the rotation of the rotation adjustment ring.

[0014] Further, the limiting plate includes a first part, a second part and a limiting part; when the limiting plate rotates until the first part is received in the second mounting groove, the second part protrudes out of the second mounting groove, and the limiting part abuts against the rotation adjustment ring.

[0015] Further, a first magnetic element is provided on the second part, and the housing further includes a second magnetic element which is fixedly installed in the second mounting groove; when the limiting plate rotates until the second part is received in the second mounting groove, the first magnetic element and the second magnetic element are attracted to each other.

[0016] Further, the housing further includes a retaining ring. A third mounting groove is also provided on the housing. The retaining ring is partially received in the third mounting groove and is fixedly connected to the housing. The retaining ring abuts against the mounting ring.

[0017] Further, the filter mounting structure further includes a second filter frame, and the second filter frame is movably adsorbed on one end of the first filter frame away from the mounting ring, and the second filter frame can rotate relative to the first filter frame.

[0018] Advantages of the present invention:

[0019] In the filter mounting structure proposed by the present invention, the first filter frame can be rotated by rotating the rotation adjustment ring. When it is necessary to rotate the second filter frame, rotate the limiting plate so that the limiting part abuts against the rotation adjustment ring. The rotation adjustment ring is limited and cannot rotate. At this time, rotating the second filter frame will not cause the first filter frame to rotate. Description of the Drawings

[0030] In this embodiment, the rotation adjustment ring 11 can rotate relative to the lens connection disk 10, a fastening connection is formed between the mounting ring 12 and the rotation adjustment ring 11, and the rotation of the rotation adjustment ring 11 drives the rotation of the mounting ring 12; magnets are provided in the first filter frame 20, the mounting ring 12 is made of iron material, the first filter frame 20 is adsorbed on the mounting ring 12 by magnetic attraction, at this time the limiting block 21 is received in the limiting groove 121, and the first filter frame 20 is limited and cannot rotate relative to the mounting ring 12.

[0031] Further, an installation part 122 is also provided on the installation ring 12. The installation part 122 is received in the rotation adjustment ring 11 and is threadedly connected to the rotation adjustment ring 11.

[0032] In this embodiment, the installation part 122 is threadedly connected to the rotation adjustment ring 11. During assembly, the installation part 122 is screwed into the rotation adjustment ring 11 to form a firm connection between the installation ring 12 and the rotation adjustment ring 11.

[0033] Further, a first positioning ring 22 is also provided on the first filter frame 20. The first positioning ring 22 is received in the installation ring 12 and abuts against the installation ring 12.

[0034] In this embodiment, the first positioning ring 22 is received in the installation ring 12 and abuts against the installation ring 12, and the first filter frame 20 is limited from sliding relative to the installation ring 12.

[0035] Further, the lens connection disk 10 further includes a housing 13. A first installation groove 131 is provided on the housing 13. The rotation adjustment ring 11 and the installation ring 12 are both movably received in the first installation groove 131, and the rotation adjustment ring 11 is located between the housing 13 and the installation ring 12.

[0036] In this embodiment, the rotation adjustment ring 11 and the installation ring 12 are both movably received in the first installation groove 131, and both the rotation adjustment ring 11 and the installation ring 12 can rotate relative to the housing 13. An annular positioning plate 137 is also provided on the housing 13, and the lens connection disk 10 can be installed on an external lens through the annular positioning plate 137.

[0037] Further, at least one adjustment groove 132 is also provided on the housing 13. The adjustment groove 132 communicates with the first installation groove 131 to expose a part of the rotation adjustment ring 11 out of the housing 13.

[0038] In this embodiment, the number of the adjustment grooves 132 is 2, and the rotation adjustment ring 11 can be rotated through the adjustment grooves 132.

[0039] Further, the filter mounting structure further includes a limiting plate 30. The outer shell 13 is further provided with a second mounting groove 133 communicating with the first mounting groove 131. The limiting plate 30 is partially received in the second mounting groove 133 and is movably connected to the outer shell 13. Rotating the limiting plate 30 causes the limiting plate 30 to abut against the rotary adjustment ring 11, thereby restricting the rotation of the rotary adjustment ring 11. The limiting plate 30 includes a first portion 31, a second portion 32, and a limiting portion 33. When the limiting plate 30 rotates until the first portion 31 is received in the second mounting groove 133, the second portion 32 protrudes out of the second mounting groove 133, and the limiting portion 33 abuts against the rotary adjustment ring 11.

[0040] In this embodiment, the limiting plate 30 is movably connected to the outer shell 13 by a screw passing through the outer shell 13 and the limiting plate 30. When it is necessary to restrict the rotation of the rotary adjustment ring 11, press the first portion 31 to rotate the limiting plate 30 until the first portion 31 is received in the second mounting groove 133. At this time, the groove wall of the second mounting groove 133 clamps the first portion 31 to restrict the first portion 31 from rotating out of the second mounting groove 133. The limiting portion 33 abuts against the rotary adjustment ring 11, and the rotary adjustment ring 11 is limited and cannot rotate.

[0041] Further, a first magnetic element 321 is provided on the second portion 32. The outer shell 13 further includes a second magnetic element 134, and the second magnetic element 134 is fixedly installed in the second mounting groove 133. When the limiting plate 30 rotates until the second portion 32 is received in the second mounting groove 133, the first magnetic element 321 and the second magnetic element 134 are attracted to each other.

[0042] In this embodiment, press the second portion 32 to rotate the limiting plate 30 until the second portion 32 is received in the second mounting groove 133. At this time, the first magnetic element 321 and the second magnetic element 134 are attracted to each other to restrict the second portion 32 from rotating out of the second mounting groove 133. The limiting portion 33 is spaced from the rotary adjustment ring 11, and the rotary adjustment ring 11 can rotate relative to the outer shell 13.

[0043] Further, the outer shell 13 further includes a retaining ring 135. The outer shell 13 is further provided with a third mounting groove 136. The retaining ring 135 is partially received in the third mounting groove 136 and is fixedly connected to the outer shell 13. The retaining ring 135 abuts against the mounting ring 12.

[0044] In this embodiment, the retaining ring 135 abuts against the mounting ring 12, thereby restricting the position of the mounting ring 12 and preventing the mounting ring 12 from disengaging from the first mounting groove 131.

[0045] Further, the filter mounting structure further includes a second filter frame 40. The second filter frame 40 is movably adsorbed on one end of the first filter frame 20 away from the mounting ring 12, and the second filter frame 40 can rotate relative to the first filter frame 20.

[0046] In this embodiment, lenses can be installed in both the first filter frame 20 and the second filter frame 40. Magnets are provided in the second filter frame 40, and magnets are also provided in the first filter frame 20. The second filter frame 40 is movably adsorbed on one end of the first filter frame 20 away from the mounting ring 12 by magnetic force. During use, if it is necessary to rotate the first filter frame 20, press the second part 32 to rotate the limiting plate 30 until the second part 32 is received in the second mounting groove 133, and drive the first filter frame 20 to rotate by rotating the rotary adjustment ring 11. If it is necessary to rotate the second filter frame 40 without rotating the first filter frame 20, press the first part 31 to rotate the limiting plate 30 until the first part 31 is received in the second mounting groove 133. At this time, rotate the second filter frame 40. Since the rotary adjustment ring 11 is restricted from rotating, the first filter frame 20 is also restricted from rotating.
