Embodiment 1

[0033] Embodiment 1, a kind of lens filter adapter ring assembly, refer to figure 1 , including filter end moving ring 1, rotating ring 2 and lens end fixed ring 3 arranged concentrically from the outside to the inside, the filter end moving ring 1 and lens end fixed ring 3 are provided with a universal Thread, the filter M is connected to the lens N through the lens filter adapter ring assembly (the fixed ring at the lens end is connected with the camera lens thread, the moving ring at the filter end is connected with the filter thread, and the connection method is a universal thread connection, which improves the lens filter. The scope of application of the mirror adapter ring assembly, easy assembly and installation); figure 2 In its exploded view, the filter end moving ring 1 and the rotating ring 2 are provided with a corresponding connecting hole 11, and a connecting shaft 12 is arranged in the connecting hole 11, and the filter end moving ring 1 and the rotating ring 2...

Embodiment 2

[0038] Embodiment 2, the difference between this embodiment and embodiment 1 is that, refer to Figure 12 , the fixed member includes a U-shaped bayonet pin 5, the distance between the inner side walls of the two ends of the U-shaped bayonet pin 5 is equal to the thickness of the rotating ring 2 and the filter end moving ring 1, and one end of the U-shaped bayonet pin 5 Fixed on the rotating ring 2 by screws 52, a semicircular groove 51 is provided on the inner wall of the other end of the U-shaped bayonet 5, and a semicircular groove 51 is correspondingly provided on the moving ring 1 of the filter end. Matching semicircular protrusions 53 .

[0039] Specifically, in the process of use, when the filter is from the inactive state to the active state, the rotating ring 1 on the end of the filter is concentric with the rotating ring 2, and the semicircular groove 51 is engaged with the semicircular protrusion 53, because the U-shaped The distance between the bayonet pins 5 is e...

Embodiment 3

[0040] Embodiment 3. The difference between this embodiment and Embodiment 1 is that the fixed member adopts a clamping shaft 6 to connect the rotating ring 2 with the moving ring 1 at the end of the filter. Refer to Figure 13 , one end of the clamping shaft 6 is hingedly connected to the rotating ring 2 (the articulation technology is relatively mature, and will not be described in detail here), that is, the clamping shaft can rotate around the hinged end, and the rotating ring 2 and the filter end move the ring 1 is provided with a card slot engaged with the card connection shaft 6 ( Figure 13 The schematic diagram shown in is snapped together, the location of the snap-in shaft is the slot), the opening diameter of the slot is slightly smaller than the diameter of the snap-in shaft, which is convenient for fixing the rotating ring 2 and the filter end moving ring 1 To prevent the clamping shaft from disengaging, in order to prevent the clamping effect from loosening after ...

Abstract

The invention discloses an adapter ring assembly of a lens and a filter. The adapter ring assembly comprises a filter end movable ring, a rotary ring and a lens end fixed ring, wherein corresponding connecting holes are formed in the filter end movable ring and the rotary ring; a connecting shaft is arranged in the connecting holes; the filter end movable ring can rotate around the connecting shaft; the rotary ring and the lens end fixed ring are clamped and the rotary ring and the lens end fixed ring can rotate oppositely on the axis around the circle center; fixing parts for fixing the filter end movable ring and the rotary ring are arranged at opposite positions, corresponding to the connecting holes, on the filter end movable ring and the rotary ring; when the filter is used, optical axes of the filter and the lens are fixed on the same axis; when the filter is not used, the filter end movable ring and the rotary ring are disconnected; the filter end movable ring rotates around the connecting shaft under the action of self-gravity of the filter and the filter automatically keeps below the lens. The filter can be rapidly selectively utilized or not utilized by a user without the need of a detaching and mounting the lens; the adapter ring assembly has wide commonality and a novel structural design and has wide popularization and application value.

Description

technical field [0001] The invention relates to the field of manufacturing auxiliary camera accessories, in particular to a lens filter adapter ring assembly. Background technique [0002] In photography, in order to obtain special effects, various filters for the front of the lens are often used, such as close-up lenses, polarizers, gradient filters, ND lenses, color temperature filters, soft focus lenses, star filters, etc. Most of these filters are round and threaded, and are threaded onto the lens when used. During use, the deactivation and use switching of the filter is relatively frequent, and because of the threaded connection, the disassembly and assembly are relatively slow, and it is possible to miss the fleeting picture. [0003] The authorized announcement number is [CN2112846U], and the utility model titled "camera color filter adapter ring" discloses a magnetic adapter ring. The structure reliability of the magnetic attraction type is low, and it is difficult ...
