Detailed implementation manners
[0016] The following further explains the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] As Figures 1-4 shown, a combined adapter ring capable of switching different lenses and camera bayonets includes a lens mounting base 11. On one side of the lens mounting base 1, there is a lens fixing ring 2, and on the other side, there is a detachable camera bayonet assembly. The camera bayonet assembly includes a camera connecting piece 3 and a locking piece. One end of the camera connecting piece 3 is sleeved on the lens mounting base 1 through a bayonet positioning structure, and the camera connecting piece 3, the locking piece, and the lens mounting base 1 are locked and connected through a locking structure. Below the lens mounting base 1, there is a tripod mounting base 4. The locking piece is a bayonet lock ring 5. The bayonet positioning mechanism includes a positioning post 7 and a positioning bayonet 305. The locking structure includes a first clamping block 501, a second clamping block 303, a first notch 502, and a second notch 304 with the same shape. On the side of the lens mounting base 1 facing the camera connecting piece 3, there are successively formed a first mounting platform 102 and a second mounting platform 102. A limit groove 103 is provided on the second mounting platform 102. A limit post 6 passes through the bayonet lock ring 5, and one end of the limit post 6 is movable within the limit groove 103. The positioning post 7 is provided on the outer side surface of the second mounting platform 102. At the ring mouth position of the bayonet lock ring 5 facing the camera connecting piece 3, the first clamping blocks 501 are arranged at intervals, and a first notch 502 is formed between two adjacent first clamping blocks 501. On one side of the camera connecting piece 3, there is a camera end bayonet 301, and on the other side, there is a sliding groove 302 for the first clamping block 501 to slide. On the outer side wall of the sliding groove 302, the second clamping blocks 303 are arranged at intervals, and a second notch 304 is formed between two adjacent second clamping blocks 303. The positioning bayonet 305 is provided on one of the second clamping blocks 303.
[0018] When installing and using, select the appropriate camera connector 3 according to the required camera. The camera end bayonet 301 on the camera connector 3 has different bayonet modes, but the structure on the side for connecting the lens mount 1 is standard. That is to say, the chute 302, the second latch 303, the second notch 304 and the positioning bayonet 305 are standard structures, which are matched with the structures on the bayonet lock ring 5 and the positioning post 7 (the design of the first latch 501 and the first notch 502 on the bayonet lock ring 5 is to match the standard structure of the camera connector 3). First, align the first notch 502 on the bayonet lock ring 5 with the second latch 303 on the camera connector 3, so that the bayonet lock ring 5 is sleeved on the camera connector 3. Then, align the positioning bayonet 305 on the camera connector 3 with the positioning post 7 for connection. Then, hold the limit post 6 on the bayonet lock ring 5 and rotate the bayonet lock ring 5 to fix it, so that the first latch 501 and the second latch 303 are in alignment. When it is necessary to replace the camera connector 3, rotate the bayonet lock ring 5 in the opposite direction. The limit post 6 slides between the two ends in the limit groove 103. Finally, install and connect the required lens and camera respectively, and then install it on the required tripod through the tripod mount 4 for use.
[0019] For the adapter ring of the present utility model, through the design of the replaceable camera bayonet assembly, only by replacing the camera bayonet assembly can different bayonet cameras be flexibly adapted. Similarly, the same camera bayonet assembly combined with different lens mounts 1 can also adapt different lenses. The structure is simple and the operation is convenient. Different cameras can be used with the same lens to improve the utilization rate of the lens; or the same camera can be adapted to different lenses to improve the applicability flexibility of the adapter ring. At the same time, the overall appearance of the combined adapter ring is more compact and has a certain aesthetic property.
[0020] Specifically, a pineapple tooth-shaped ring 8 is formed on the outer wall of the bayonet lock ring 5. With the above design, the design of the pineapple tooth-shaped ring 8 can improve the overall aesthetic property of the adapter ring. At the same time, the operation feel of the bayonet lock ring 5 is more comfortable and stable.
[0021] Specifically, the limit post 6 sequentially includes a tapered head 601, a first cylindrical section 602, a second cylindrical section 603 and a third cylindrical section 604, and the outer diameters decrease sequentially. A limit post connection groove 503 is provided at the pineapple tooth-shaped ring 8 of the bayonet lock ring 5. A through hole 504 for passing through the second cylindrical section 603 is formed below the limit post connection groove 503, and a notch is formed at the lower port of the through hole 504. The third cylindrical section 604 is located in the limit groove 103. With the above design, the structure of the limit post 6 is simple and compact, and it can be better squeezed into the through hole 504 for tight connection, which is convenient for the turning operation of the bayonet lock ring 5 and improves the convenience and stability of the operation.
[0022] Specifically, on the side of the lens mount 1 facing the lens fixing ring 2, an installation groove 104 is formed. A groove 105 is provided on the installation groove 104. A lens release button 9 is arranged in the groove 105, and the lens release button 9 is exposed from the installation groove 104 through a notch. The lens fixing ring 2 is connected to the installation groove 104. With the above design, it is convenient to install the lens through the lens release button 9, and the lens fixing ring 2 can strengthen the installation effect of the lens.
[0023] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included within the protection scope of the present invention.
