When using, main support 100 is installed to the shell of photographic instrument, multiple optical assemblies are installed to multiple conversion frame 200 respectively, and the optical assembly required currently is adjusted to the shooting window on the shell. When other optical assembly needs to be replaced to the shooting window, the conversion frame 200 corresponding to the optical assembly currently is adjusted, the optical assembly currently is transferred away from the shooting window, and the required conversion frame 200 and the required optical assembly are transferred to the target position, without needing to remove the optical assembly currently and install the required optical assembly, which can facilitate the consumer to operate and use, can avoid optical assembly loss, and can avoid causing economic loss.

[0027] It needs to be explained that the photographic instrument in the utility model can be photographic equipment such as mobile phone or camera, or photographic auxiliary equipment such as mobile phone waterproof diving shell. Some existing photographic instruments such as mobile phone diving waterproof shell are provided with a support for installing optical assembly, so the shell itself has a position or structure for installing the support. The main support 100 in the application is provided with a screw hole 130, and can be directly installed on the position of the original support on the shell by screw, so the shell structure of the photographic instrument does not need to be improved. In other words, the optical assembly conversion structure in the application can be directly installed on the shell of some existing photographic instruments, and the photographic instruments do not need to be provided with new photographic instruments.

[0028] When the optical assembly conversion structure in the utility model is used, the optical assembly does not need to be removed from the conversion frame 200, and the conversion frame 200 does not need to be removed from the main support 100, but the relative position between the conversion frame 200 and the main support 100 can be directly adjusted. The optical assembly in the utility model refers to optical imaging structure such as lens or lens, for example, wide-angle lens, macro lens or filter lens.

[0029] The "conversion frame 200 movably connected with main support 100" in the utility model can be slidably connected with the main support 100, or rotatably connected with the main support 100, as long as the position can be adjusted.

[0030] The plurality of conversion frames 200 in the utility model can be two, three or other number, and can be specifically designed to adapt to the size of the shell of the photographic instrument, for example, two conversion frames 200 can be selected and arranged when applied in a waterproof diving shell, and two different optical assemblies are equipped for use. Of course, the plurality of conversion frames 200 can be integrally formed into one support or can be designed into a plurality of supports in a split type.

[0031] The embodiments of the utility model will be described in detail below:

[0032] Embodiment one

[0033] With reference to Figures 1 to 3 Embodiment one of the utility model provides an optical assembly conversion structure, including main support 100 and two conversion frames 200, the positioning hole 210 is set up on each conversion frame 200, for positioning installation optical assembly, and the optical assembly can be positioned and installed in the positioning hole 210 through the buckle or threaded connection mode. Further, two conversion frames 200 are fixed as a whole, and form an integral type adjusting support 400, when adjusting support 400 is active relative to main support 100, one of conversion frames 200 gradually moves away from the target position on the shooting window, and simultaneously, the other conversion frame 200 gradually approaches the target position on the shooting window.

[0034] Further, adjusting support 400 can be slidably and / or rotatably connected with main support 100, for example, adjusting support 400 can be slidably connected with main support 100, at this time, two conversion frames 200 can be arranged side by side. When sliding adjusting support 400 along the first direction, the first conversion frame 200 can gradually move away from the target position on the shooting window, and simultaneously, the second conversion frame 200 can gradually approach the target position on the shooting window. When sliding adjusting support 400 along the second direction, the first conversion frame 200 can gradually approach the target position on the shooting window, and simultaneously, the second conversion frame 200 can gradually move away from the target position on the shooting window. For another example, adjusting support 400 can be rotatably connected with main support 100, at this time, two conversion frames 200 can be arranged in an angle type. When rotating adjusting support 400, the first conversion frame 200 can gradually move away from the target position on the shooting window, and simultaneously, the second conversion frame 200 can gradually approach the target position on the shooting window. When continuing to rotate adjusting support 400 along the same direction or along the opposite direction, the first conversion frame 200 can gradually approach the target position on the shooting window, and simultaneously, the second conversion frame 200 can gradually move away from the target position on the shooting window. Of course, in order to better adjust the position of the optical assembly, in the embodiment, adjusting support 400 can slide relative to main support 100 and can also rotate relative to main support 100.

[0035] Further, the main support 100 and the adjusting support 400 are connected through the lock structure 300. When the lock structure 300 is adjusted to the first position, the main support 100 and the adjusting support 400 can be loosened, and at this time, the required optical assembly can be adjusted to the target position. When the lock structure 300 is adjusted to the second position, the main support 100 and the adjusting support 400 can be locked, and the required optical assembly can be kept in the current position for shooting. Further, the adjusting support 400 includes two conversion supports 200, and the two conversion supports 200 are distributed in a "V" shape. When the adjusting support 400 is rotated, one of the conversion supports 200 will inevitably protrude below the shell. When shooting at a low position, the conversion support 200 may touch the bottom of the water or the ground. In the embodiment, the two conversion supports 200 are distributed in a "V" shape, so that the conversion support 200 can be kept from being located directly below the shell, thereby facilitating shooting at a lower position.

[0036] Further, the lock structure 300 includes a lock seat 310 and an adjusting piece 320. The first end of the lock seat 310 is provided with a limiting part 311, and the lock seat 310 is sequentially inserted into the main support 100 and the adjusting support 400. The second end of the lock seat 310 is movably connected with the adjusting piece 320. When the adjusting piece 320 is moved to the first position relative to the lock seat 310, the main support 100 and the adjusting support 400 can be loosened. When the adjusting piece 320 is moved to the second position relative to the lock seat 310, the adjusting piece 320 can be matched with the limiting part 311 to lock the main support 100 and the adjusting support 400. The movable connection between the adjusting piece 320 and the lock seat 310 can be rotary connection or sliding connection. Of course, it can be understood that the first position and the second position of the adjusting piece 320 are not the exact positions. The first position and the second position correspond to the state of the adjusting piece 320. As long as the adjusting piece 320 is moved to the position where the main support 100 and the adjusting support 400 are loosened, it can be considered as the first position. As long as the adjusting piece 320 is moved to the position where the main support 100 and the adjusting support 400 are locked, it can be considered as the second position.

[0037] Further, referring to Figure 4 and Figure 5The adjusting member 320 comprises a movable connecting portion 321 and a handle 322, the movable connecting portion 321 is rotatably connected to the lock seat 310, and the handle 322 is fixedly connected to the movable connecting portion 321. When the movable connecting portion 321 rotates relative to the lock seat 310, it can be pressed towards the main support 100 and the adjusting support 400 to lock the main support 100 and the adjusting support 400, or it can be moved away from the main support 100 and the adjusting support 400 to unlock the main support 100 and the adjusting support 400. Further, the lock structure 300 further comprises an elastic pad 330 and a movable piece 340, the elastic pad 330 is sleeved on the lock seat 310 and located between the main support 100 and the adjusting support 400, and the movable piece 340 is located between the adjusting support 400 and the movable connecting portion 321. The second end of the lock seat 310 is provided with a rotating pin 312, and the extending direction of the rotating pin 312 is perpendicular to the extending direction of the lock seat 310, and the movable connecting portion 321 is rotatably connected to the rotating pin 312; the movable connecting portion 321 has a first pressing surface 3211 and a second pressing surface 3212, and the distance from the first pressing surface 3211 to the rotating pin 312 is smaller than the distance from the second pressing surface 3212 to the rotating pin 312. When the adjusting member 320 moves relative to the lock seat 310 to the first position, the first pressing surface 3211 faces the main support 100 and the adjusting support 400, but does not exert force on the main support 100 and the adjusting support 400, so it will not cause the main support 100 and the adjusting support 400 to be locked, at this time the adjusting support 400 can be greatly slid to quickly convert the required optical components to the position. When the adjusting member 320 moves relative to the lock seat 310 to the second position, the second pressing surface 3212 faces the main support 100 and the adjusting support 400, and since the distance from the second pressing surface 3212 to the rotating pin 312 is larger, at this time the second pressing surface 3212 will exert force on the main support 100 and the adjusting support 400, thereby locking the main support 100 and the adjusting support 400, but since the elastic pad 330 exists, the main support 100 and the adjusting support 400 are not completely locked, and the deformable ability of the elastic pad 330 can provide a fine adjustment gap for the main support 100 and the adjusting support 400, at this time the adjusting support 400 can be finely adjusted to adjust the required optical components to a better position. Further, the first pressing surface 3211 and the second pressing surface 3212 are connected by a transition arc surface 3213, so that when the consumer exerts force on the handle 322, the movable connecting portion 321 can smoothly switch between the unlocked state and the locked state.

[0038] In some other embodiments, the elastic pad 330 can also be arranged between the limiting part 311 and the main support 100, and between the adjusting support 400 and the adjusting part 320, as long as the elastic pad 330 is not pressed when the adjusting part 320 is moved to the first position relative to the lock seat 310, so that the adjusting support 400 can be moved greatly, and the elastic pad 330 is pressed when the adjusting part 320 is moved to the second position relative to the lock seat 310, but still has an adjusting allowance, so that the adjusting support 400 can be finely adjusted when subjected to an external force.

[0039] Further, referring to Figure 3 , the main support 100 is provided with a first sliding groove 110, the adjusting support 400 is provided with a mounting hole, the lock seat 310 is sequentially connected to the first sliding groove 110 and the mounting hole, and the lock seat 310 can slide along the first sliding groove 110 to drive the adjusting support 400 connected with the lock seat 310 to slide along the main support 100. The main support 100 is also provided with a second sliding groove 120, the first sliding groove 110 penetrates into the second sliding groove 120, the limiting part 311 is circular, and the limiting part 311 is slidably and rotatably connected to the second sliding groove 120. When the lock seat 310 slides along the first sliding groove 110, the limiting part 311 also slides along the second sliding groove 120, and when the adjusting support 400 is rotated, the circular limiting part 311 can also rotate in the second sliding groove 120, so as to better adjust the position between the main support 100 and the adjusting support 400.
