Description

Technical Field

[0001] The utility model relates to the technical field of camera components, in particular to a high-precision camera sheet metal structure. Background Art

[0002] A camera is an instrument used to record dynamic images. Its working principle is to record images by converting optical image signals into electrical signals, and then storing or transmitting the electrical signals. During the production process of cameras, it is usually necessary to use sheet metal components to assemble the camera housing and wrap the camera parts to achieve structural support for the camera.

[0003] A Chinese patent, publication number CN210112103U, discloses a sheet metal housing for a camera movement. The key technical features of this solution include a front cover, a rear cover, and a rotary adjustment mechanism. The front cover is connected to the rear cover via screws, and the movement is housed within the front cover. This rotary adjustment mechanism, combined with a strip of springs punched into the front cover, enhances stability and improves shooting quality in shaky environments. A notch on one side of the front cover allows the movement to be rotated using the rotary adjustment mechanism in the event of a problem, making maintenance more convenient and saving labor costs.

[0004] The existing related technologies often have the following defects: when installing the camera core into the camera sheet metal structure in the existing technology, the connecting plate and the camera core need to be connected by a connecting rod. Since the movement of the connecting plate and the connecting rod needs to be controlled by adjusting the screw during the process of inserting the connecting rod into the camera core, the accuracy of inserting the connecting rod into the camera core is poor, thereby reducing the efficiency of installing the camera core.

[0005] Therefore, the utility model provides a high-precision camera sheet metal structure. Utility Model Content

[0030] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a high-precision camera sheet metal structure, including a front shell 1, a sealing plate 3 is detachably installed on one side of the front shell 1, a camera core 2 is installed inside the front shell 1, and an adjustment mechanism 4 is provided on the side of the sealing plate 3 close to the camera core 2. The adjustment mechanism 4 includes an adjusting screw 41, and the adjusting screw 41 is threadedly inserted into the inner wall of the sealing plate 3. The surface of the adjusting screw 41 is fixedly connected to a fixing plate 42, and the surface of the adjusting screw 41 is sleeved with a connecting plate 43. Four connecting rods 44 are fixedly connected to the side of the connecting plate 43 close to the camera core 2, and one end of the adjusting screw 41 close to the camera core 2 is fixedly connected to a limiting block 45. A connecting device 5 is provided on the side of the connecting plate 43 close to the camera core 2, and a limiting device 6 is provided on the side of the fixing plate 42.

[0031] The specific configuration and function of the connecting device 5 and the limiting device 6 will be described in detail below.

[0032] Reference Figure 1-Figure 4As shown, in this embodiment, the connecting device 5 includes four pressing blocks 51, each mounted on the side of the connecting plate 43 near the camera core 2. Each of the four pressing blocks 51 is fixedly connected to an arc-shaped block 52 on the side away from the stop block 45. Four vertical plates 55 are fixedly connected to the side of the connecting plate 43 near the pressing blocks 51. The pressing blocks 51 can cooperate with the stop block 45 and the fixed plate 42 to restrict the movement of the connecting plate 43. The arc-shaped blocks 52 can be used to adjust the position of the pressing blocks 51 using the stop block 45 when connecting the adjusting screw 41 to the connecting plate 43. Slide grooves are formed on the sides of the four vertical plates 55 near the stop block 45. Sliders 56 are slidably connected to the surfaces of the slide grooves on the four vertical plates 55. Slide rods 53 are fixedly connected to the sides of the sliders 56 near the pressing blocks 51. The slide rods 53 are slidably connected to the inner wall of the pressing block 51. The slider 56 slidably connected to the sliding groove surface of the vertical plate 55 can move. By providing the slider 56 , the sliding rod 53 and the pressing block 51 can be connected to the vertical plate 55 while ensuring that the sliding rod 53 and the pressing block 51 can move.

[0033] The surface of the slide bar 53 is covered with a first spring 54, and the two ends of the first spring 54 are fixedly connected to the slider 56 and the pressure block 51, respectively. By providing the first spring 54, a stable connection between the slide bar 53 and the pressure block 51 can be ensured, and the position of the pressure block 51 can be restricted. The inner wall of the slider 56 is slidably connected to a fixed rod 57, which is fixedly connected to the surface of the slide groove on the vertical plate 55. The surface of the fixed rod 57 is covered with a second spring 58, and the two ends of the second spring 58 are fixedly connected to the slider 56 and the vertical plate 55, respectively. By providing the fixed rod 57, the position of the second spring 58 can be restricted, and by providing the second spring 58, the position of the slider 56 can be restricted.

[0034] Reference Figure 2 and Figure 5 As shown, specifically, the limiting device 6 includes a gear 61 fixedly connected to the surface of the connecting plate 43. A curved plate 62 is fixedly connected to the side of the fixed plate 42. A limiting rod 63 is threadedly inserted into the inner wall of the curved plate 62. The curved plate 62 allows the limiting rod 63 to be connected to the fixed plate 42. By providing the limiting rod 63 and the gear 61, the connecting plate 43 can be restricted, thereby ensuring that it can rotate with the rotation of the fixed plate 42.

[0035] The limiting rod 63 is sheathed with a sleeve rod 65. A handle 66 is fixedly connected to the end of the sleeve rod 65 away from the curved plate 62. The handle 66 facilitates the movement of the sleeve rod 65, and by controlling the rotation of the sleeve rod 65, the rotation of the limiting rod 63 can be easily controlled. A third spring 64 is fixedly connected to the end of the limiting rod 63 near the sleeve rod 65. The other end of the third spring 64 is fixedly connected to the sleeve rod 65. The third spring 64 ensures a stable connection between the sleeve rod 65 and the limiting rod 63, while ensuring that the rotation of the sleeve rod 65 drives the rotation of the limiting rod 63.

[0036] Working principle: when installing the camera core 2 into the front shell 1, first move the camera core 2 to the inside of the front shell 1, then move the connecting plate 43 so that the connecting rod 44 is stuck in the camera core 2, and then move the sealing plate 3 so that the adjusting screw 41 of the adjusting mechanism 4 passes through the connecting plate 43. During this process, the limit block 45 pushes the arc block 52 to make the pressure block 51 move closer to the camera core 2. When the arc block 52 moves away from the connecting plate 43, the limit block 45 pushes the arc block 52 to make the pressure block 51 slide on the surface of the slide rod 53. At the same time, the slide rod 53 drives the slider 56 to slide on the surface of the fixed rod 57. When the limit block 45 moves away from the pressure block 51, under the action of the elastic force of the second spring 58, the slider 56 moves close to the connecting plate 43. At the same time, under the action of the elastic force of the first spring 54, the pressure block 51 moves away from the vertical plate 55, completing the connection between the adjusting screw 41 and the connecting plate 43. By setting the connecting device 5, in the process of installing the camera core 2 into the front shell 1, the connecting plate 43 and the camera core 2 can be connected first through the connecting rod 44, thereby ensuring the accuracy of installing the connecting rod 44 into the camera core 2 as much as possible and improving the efficiency of installing the camera core 2.

[0037] When installing the closing plate 3, first move the sleeve rod 65 to make it slide on the surface of the limit rod 63, so as to control the sleeve rod 65 to pass through the closing plate 3, grab the handle 66, and then install the closing plate 3. After completing the installation of the closing plate 3, turn the handle 66 to drive the sleeve rod 65 and the limit rod 63 to rotate. At this time, the limit rod 63 rotates on the inner wall of the arc plate 62, so that the limit rod 63 moves close to the gear 61, thereby limiting the rotation of the connecting plate 43, and then release the handle 66. At this time, under the action of the elastic force of the third spring 64, the sleeve rod 65 moves close to the fixed plate 42, completing the rotation restriction of the connecting plate 43. By setting the limit device 6, after the adjusting screw 41 passes through the connecting plate 43, the rotation of the connecting plate 43 can be conveniently restricted, thereby reducing the complexity of restricting the rotation of the connecting plate 43 as much as possible, and facilitating the installation of the camera core 2.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
