Description

Technical Field

[0001] The utility model relates to the technical field of camera accessories, in particular to a digital camera back adapter plate. Background Art

[0002] A digital back adapter plate is a device used to connect a digital back to a conventional camera body, allowing photographers to shoot with the digital back without changing the camera body. Digital back adapter plates come in a variety of designs to accommodate different brands and models of cameras and digital backs. They typically include an interface and mounting structure to ensure the digital back is securely attached to the camera body and transmit image data. Using a digital back adapter plate can expand camera functionality, improving shooting quality and flexibility.

[0003] After searching, the patent with authorization announcement number CN 204203609 U is a digital back adapter plate, which is installed between the digital back and the camera body to fix the digital back to the camera body. It includes a rectangular base plate with a square hole in the middle. A clamping device that can be connected to the camera body is provided on the front side of the rectangular base plate, and a fixing device that can be connected to the digital back is provided on the rear side. The clamping device includes a clamping plate, and the four corners where the clamping plate is connected to the rectangular base plate are respectively provided with clamping grooves. A square hole is provided in the middle of the clamping plate, and the shape of the square hole is larger than the square hole; the fixing device includes a hook plate arranged on the upper part of the rectangular base plate and a support plate arranged on the lower part of the rectangular base plate. The hook plate and the support plate respectively cooperate with the connecting device of the camera body.

[0004] The above-mentioned patent only uses two hook-shaped claws to connect with the connecting device of the digital back. Although this structure can play a good fixing role, the hook-shaped claws are a protruding structure and are easily squeezed during storage, resulting in deformation, etc., and have low strength and are prone to damage. Therefore, in order to solve the above-mentioned problems, we propose a digital back adapter plate. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0025] Reference Figure 1-5 A digital back adapter plate includes a base plate 3, a connecting plate 1 is fixedly installed on the front of the base plate 3, screw holes 2 are opened at the four ends and left and right sides of the connecting plate 1 and the base plate 3, and a light-shielding groove 6 is opened on the back of the base plate 3; the light-shielding groove 6 is used to match the light-shielding device on the body to prevent light leakage and ensure the normal operation of the photosensitive chip.

[0026] The base plate 3 can be installed on the camera body (not shown in the figure) by screwing into the screw hole 2, the connecting plate 1 can be installed on the front of the base plate 3 by screwing into the screw hole 2, and the digital back (not shown in the figure) can be installed on the front of the connecting plate 1.

[0027] A rectangular convex ring 12 is fixedly mounted on the front side of the base plate 3 . The rectangular convex ring 12 is located at the front end of the photosensitive chip window inside the base plate 3 . The inner diameter of the rectangular convex ring 12 is the same as that of the photosensitive chip window.

[0028] The setting of the rectangular convex ring 12 can realize the connection of the two photosensitive chip windows, effectively block the gap between the base plate 3 and the connecting plate 1, and reduce the refraction and reflection of light.

[0029] A receiving slot is defined on the front of the base plate 3, within which a connecting assembly is slidably mounted. Corresponding photosensitive chip windows are defined within both the base plate 3 and the connecting plate 1. The connecting assembly comprises a movable frame 9, the inner diameter of which is greater than that of the rectangular protruding ring 12. The length and width of the movable frame 9 are both smaller than those of the receiving slot. Gourd-shaped holes 8 are defined at each of the four ends of the movable frame 9, while the connecting plate 1 has four through-holes corresponding to the gourd-shaped holes 8.

[0030] The digital back can be inserted into the gourd hole 8 through the protrusion structure adapted to the gourd hole 8. After the movable frame 9 moves, it can drive the gourd hole 8 to move, so that the protrusion cannot escape from the gourd hole 8, thereby realizing the connection between the digital back and the connecting plate.

[0031] A movable bar 4 is fixedly installed on one side of the top of the movable frame 9, a groove 10 is provided on the upper side of the front of the base plate 3, the top of the movable bar 4 passes through the groove 10 and is fixedly installed with a dial plate 5, a through groove 7 is provided inside the movable bar 4, a spring 11 is fixedly installed at the bottom inside the groove 10, and the top of the spring 11 is fixedly connected to the top inside the through groove 7.

[0032] The user can move the movable bar 4 through the dial plate 5, and the movable bar 4 can drive the movable frame 9 to move, thereby realizing the movement of the gourd hole 8 and achieving rapid installation and removal of the digital back; the spring 11 can push the movable bar 4 to move away from the base plate 3, and realize the automatic reset of the movable frame 9.

[0033] The top of the movable frame 9 and the top of the inner side of the receiving groove are both fixedly embedded with corresponding magnets 15 that can attract each other.

[0034] The top of the movable frame 9 can be adsorbed on the top of the inner side of the receiving groove by the magnet 15, so that the movable frame 9 is fixed, which can improve the stability of the digital back after being connected to the connecting plate 1.

[0035] Limiting blocks 14 are fixedly installed on both the left and right sides of the back of the movable frame 9 . A limiting groove 13 is provided inside the accommodating groove, and the limiting blocks 14 are located inside the limiting groove 13 .

[0036] The limiting block 14 and the limiting slot 13 are used to limit the movement range of the movable frame and increase the stability of the movable frame 9.
