Description

Technical Field

[0001] This utility model relates to the field of camera pivot technology, and more specifically, to a pivot for multi-angle positioning of digital camera screens. Background Technology

[0002] Cameras have gradually become an indispensable item in people's lives for recording life. People use cameras to take pictures of landscapes or selfies. Traditionally, the camera lens and image display screen are located on opposite sides of the camera, and the screen can be flipped relative to the camera body. A pivot structure is required when flipping.

[0003] In modern photography, shooting scenarios are becoming increasingly diverse. For example, when shooting details inside buildings, the internal structure of industrial products, or micro-ecosystems in the natural environment, the space is often very small. In such cases, the camera body needs to be as close as possible to the subject to obtain a clear and complete image. However, traditional camera screens have fixed positions or limited adjustment ranges, making it difficult for photographers to view the screen for composition, focusing, and parameter adjustments. Furthermore, when shooting in crowded places or on rugged terrain, the surrounding crowds may obstruct the view of the screen. In rugged terrain, maintaining balance and placing the camera are also difficult, which greatly restricts the photographer's position and posture, forcing the photographer to adopt uncomfortable shooting postures, making it difficult to complete the shooting task.

[0004] Therefore, a pivot for multi-angle positioning of digital camera screens is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pivot for multi-angle positioning of digital camera screens to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pivot for multi-angle positioning of a digital camera screen, comprising a fixed support, a slide rail, an adjusting slide plate, and a rotating connecting ear. A primary support is provided on the right side of the fixed support, and a first damping rotating shaft is installed at both ends of the connection between the fixed support and the primary support. A secondary support is provided on the right side of the primary support. The slide rail is installed at both ends of the inner cavity of the primary support, and a baffle is provided at one end of the slide rail. A sliding cavity is opened in the inner cavity of the slide rail. The adjusting slide plate is installed at both ends of the inner cavity of the secondary support, and a limit slider is installed on the surface of the adjusting slide plate away from the secondary support.

[0007] A tertiary support is provided on the right side of the secondary support. The rotating connecting ears are respectively located on the opposite sides of the bottom of the secondary support and the tertiary support. A second damping shaft is installed in the inner cavity of the two sets of rotating connecting ears. A rotating support is provided on the right side of the tertiary support. A third damping shaft is installed at both ends of the connection between the tertiary support and the rotating support.

[0008] Preferably, the limiting slider is connected to the adjusting slide plate by bolts, and the end of the adjusting slide plate away from the secondary bracket is inserted into the inner cavity of the slide rail and locked into the slide cavity to achieve limiting. The inner cavity of the slide cavity forms a plurality of holes for the limiting slider to be locked into.

[0009] Preferably, when the adjusting slide plate is engaged in the inner cavity of the sliding cavity, the adjusting slide plate and the limiting slider abut against one side of the baffle.

[0010] Preferably, the two sets of rotating connecting ears are movably connected by the second damping shaft, and the third-level bracket is movably connected to the rotating support frame by the third damping shaft.

[0011] Preferably, rotating the rotating support changes the angle of the third-level support, thus adjusting the rotation angle between the second-level support and the third-level support.

[0012] Preferably, the opposing surfaces of the primary, secondary, and tertiary supports are provided with gaps for adjustment, and the surfaces of the primary, secondary, and tertiary supports are provided with round holes for bolt installation.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with existing technologies, the pivot for multi-angle positioning of digital camera screens uses a slide rail structure composed of a slide rail, an adjustment slide plate, and a limit slider. This allows the pivot structure to achieve extended telescopic function, further extending the adjustment range of the distance between the screen and the camera body. This allows the camera to penetrate into confined spaces and get as close as possible to the shooting scene, making it easier for photographers to view the screen from the outside in confined spaces and complete the shooting better.

[0015] 2. Compared with existing technologies, this pivot for multi-angle positioning of digital camera screens allows users to flexibly adjust the screen angle according to their shooting posture and perspective needs through the 360-degree rotation function of the rotating connecting ear. Users can observe the shooting scene from different angles. In narrow spaces, crowds, or rugged mountainous areas, users can rotate the screen to a suitable and easy-to-view angle, making it convenient for users to operate the camera and view the shooting scene.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 5 The pivot shown is used for multi-angle positioning of a digital camera screen. It includes a fixed support 1, a slide rail 5, an adjusting slide plate 7 and a rotating connecting ear 11. A primary support 3 is provided on the right side of the fixed support 1. A first damping rotating shaft 2 is installed at both ends of the connection between the fixed support 1 and the primary support 3. A secondary support 4 is provided on the right side of the primary support 3. The slide rail 5 is installed at both ends of the inner cavity of the primary support 3. A baffle 51 is provided at one end of the slide rail 5. A sliding cavity 6 is opened in the inner cavity of the slide rail 5. The adjusting slide plate 7 is installed at both ends of the inner cavity of the secondary support 4. A limit slider 8 is installed on the surface of the adjusting slide plate 7 away from the secondary support 4.

[0025] A tertiary support 9 is provided on the right side of the secondary support 4. Rotary connecting ears 11 are respectively provided on the opposite sides of the bottom of the secondary support 4 and the tertiary support 9. The inner cavity of the two sets of rotating connecting ears 11 is equipped with a second damping shaft 10. A rotating support 12 is provided on the right side of the tertiary support 9. A third damping shaft 13 is installed at both ends of the connection between the tertiary support 9 and the rotating support 12.

[0026] Among them: the fixed support 1 is installed on the camera and serves as the foundation of the entire pivot structure. The fixed support 1 is responsible for firmly installing the pivot system inside the digital camera, ensuring that other components have a stable and reliable support point when making various angle adjustments and movements. The first damping pivot 2 itself has good damping performance. Its internal structure design enables stable and uniform resistance to be generated during rotation, providing a comfortable feel for user operation. It can also effectively prevent the screen from rotating rapidly due to accidental collisions or excessive force. It can accurately control the stopping position of the first-level bracket 3 at any angle. As the intermediate link connecting the fixed support 1 and the second-level bracket 4, the first-level bracket 3 undertakes the role of transmitting and converting motion. It must not only ensure its own stable rotation relative to the fixed support 1, but also provide reliable support and guidance for the telescopic movement of the second-level bracket 4.

[0027] The sliding cavity 6, serving as the internal cavity of the slide rail 5, provides precise housing and guiding space for the adjusting slide plate 7 and the limiting slider 8. Its dimensional accuracy and surface quality are controlled. By adjusting the sliding of the slide plate 7 within the sliding cavity 6, the extension or retraction length of the secondary support 4 can be precisely controlled, meeting the screen position requirements in various confined spaces. The limiting slider 8, through its internal spring pin and the limiting engagement within the sliding cavity 6, effectively prevents the adjusting slide plate 7 from moving accidentally due to gravity. The baffle 51 prevents the adjusting slide plate 7 from protruding from the sliding cavity 6. The secondary support 4 can achieve telescopic movement via the slide rail 5 of the primary support 3, and can also achieve horizontal screen positioning via a rotatable connection with the tertiary support 9. The multi-angle rotation further enriches the screen's positioning methods. It is connected to the third-level bracket 9 through the rotating connecting ear 11 and the second damping shaft 10, allowing the third-level bracket 9 to rotate flexibly based on the second-level bracket 4. The coordinated work of the two can realize the screen's all-round rotation on the horizontal plane, making it convenient for users to observe the shooting scene from different angles. The rotating connecting ear 11 is designed with high-strength materials and a reasonable structural shape, which can withstand various torques generated by the second-level bracket 4 and the third-level bracket 9 during rotation. During the rotation of the second-level bracket 4 and the third-level bracket 9, the second damping shaft 10 can provide a smooth rotation feel and prevent the screen from shaking or losing control due to rapid rotation.

[0028] As the last adjustment component in the pivot structure, the third-level bracket 9 provides greater flexibility for screen angle adjustment. Through its rotatable connection with the second-level bracket 4 and its connection with the third damping shaft 13 of the rotating support 12, it can achieve multi-angle adjustment of the screen in the vertical and horizontal directions, allowing users to adjust the screen to almost any desired position. The third damping shaft 13 is mainly responsible for controlling the vertical angle adjustment of the rotating support 12 relative to the third-level bracket 9.

[0029] Example 2

[0030] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0031] In a preferred embodiment, the limiting slider 8 is connected to the adjusting slide plate 7 by bolts. The end of the adjusting slide plate 7 away from the secondary support 4 is inserted into the inner cavity of the slide rail 5 and locked into the slide cavity 6 to achieve limiting. The inner cavity of the slide cavity 6 forms several holes for the limiting slider 8 to be locked in. Furthermore, the bolt connection can ensure that there will be no loosening or displacement between the limiting slider 8 and the adjusting slide plate 7. The user can extend and retract the adjusting slide plate 7 to different positions according to actual needs, and fix it by precisely locking the limiting slider 8 into the corresponding holes. When the adjusting slide plate 7 and the limiting slider 8 are pushed out, the pin on the limiting slider 8 will move along the slide cavity 6. When the pin reaches the next hole position, under the action of the spring, the pin will automatically lock into the hole, thereby realizing the step-by-step locking and positioning of the blade. When the blade is retracted, the reaction force of the spring will push it back into the retracted position.

[0032] In a preferred embodiment, when the adjusting slide plate 7 is inserted into the inner cavity of the slide cavity 6, the adjusting slide plate 7 and the limiting slider 8 abut against one side of the baffle 51; furthermore, the baffle 51 forms a physical blocking mechanism to prevent the adjusting slide plate 7 from excessively extending or retracting from the slide rail 5 due to unexpected circumstances during the extension and retraction process.

[0033] In a preferred embodiment, the two sets of rotating connecting ears 11 are movably connected by a second damping pivot 10, and the tertiary support 9 is movably connected to the rotating support 12 via a third damping pivot 13. Furthermore, the movable connection of the two sets of rotating connecting ears 11 via the second damping pivot 10 provides precise control over the rotation between the secondary support 4 and the tertiary support 9, allowing the user to feel appropriate resistance when adjusting the horizontal angle of the screen, enabling the user to precisely control the speed and angle of rotation. The third damping pivot 13 connects the tertiary support 9 and the rotating support 12, allowing precise control over the vertical angle adjustment of the screen as well. When shooting objects at high or low angles, the user can finely adjust this pivot to vertically adjust the screen to the ideal angle.

[0034] In a preferred embodiment, rotating the rotating support 12 changes the angle of the third-level support 9 and adjusts the rotation angle between the second-level support 4 and the third-level support 9. Furthermore, by rotating the rotating support 12 to change the angle of the third-level support 9 and adjusting the rotation angle between the second-level support 4 and the third-level support 9, the screen can be flexibly adjusted at multiple angles to adapt to different narrow spaces.

[0035] In a preferred embodiment, the opposing surfaces of the primary support 3, the secondary support 4, and the tertiary support 9 are provided with clearances for adjustment, and the surfaces of the primary support 3, the secondary support 4, and the tertiary support 9 are provided with round holes for bolt installation. Furthermore, the clearances for adjustment between the opposing surfaces of the primary support 3, the secondary support 4, and the tertiary support 9 provide sufficient space for movement between the supports, avoiding interference between components during angle adjustment and extension / retraction operations. The round holes for bolt installation allow bolts to be used to precisely fix the various components together during the production process.

[0036] The working process of this utility model is as follows: First, when the camera screen needs to be opened, it is fixed inside the camera based on the fixed support 1. The first damping shaft 2 begins to function. The damping structure formed by the spring on the shaft and the fixed plate abuts against the first-stage support 3 and the fixed support 1. The first-stage support 3 can rotate outward relative to the fixed support 1 at a smooth and controllable speed. Then, the second-stage support 4 begins to extend through the cooperation of the slide rail 5 and the adjusting slide plate 7. The adjusting slide plate 7 slides in the slide cavity 6, and the linkage limit slider 8 moves along the trajectory of the slide cavity 6 and supports the pin by spring at the predetermined cavity position. The system locks in place, allowing for precise extension and retraction of the secondary support 4. The baffle 51 ensures that the adjusting slide plate 7 and the limiting slider 8 do not overextend. Then, the tertiary support 9 rotates relative to the secondary support 4 via the second damping shaft 10 within two sets of rotating connecting ears 11. The resistance provided by the second damping shaft 10 makes the rotation of the tertiary support 9 both flexible and stable. Users can rotate the tertiary support 9 to a suitable horizontal angle according to actual shooting needs to adjust the screen's orientation to fit confined spaces. Finally, the rotating bracket 12 adjusts its vertical angle relative to the tertiary support 9 via the third damping shaft 13. Users can rotate the rotating bracket 12; the damping characteristics of the third damping shaft 13 allow for precise control of the screen's vertical tilt angle, enabling the screen to be precisely positioned at the optimal viewing angle. Simultaneously, due to the pre-reserved adjustment gaps between the primary support 3, secondary support 4, and tertiary support 9, the angle adjustments of each support will not interfere with each other.

[0037] When the screen angle needs to be adjusted, the angle of the primary support 3 can be adjusted via the first damping pivot 2, changing the overall tilt of the screen. The second damping pivot 10 allows the tertiary support 9 to be precisely adjusted in the horizontal direction to adapt to changes in confined spaces or user viewing angles. The third damping pivot 13 allows for fine adjustment of the screen's vertical angle. When the camera screen needs to be closed, the entire process is the reverse of the unfolding process. The rotating support 12 returns to its initial vertical angle via the third damping pivot 13. Then, the tertiary support 9 rotates in the opposite direction via the second damping pivot 10, gradually approaching the secondary support 4. The secondary support 4 retracts by adjusting the sliding plate 7 in the reverse sliding within the sliding cavity 6. The limiting slider 8 retracts from its current cavity position until the adjusting plate 7 is fully retracted. The secondary support 4 returns to its initial state of close contact with the primary support 3. The primary support 3 rotates in the opposite direction via the first damping pivot 2, folding back to one side of the fixed support 1, completing the camera screen closing process. The above describes the working principle of this pivot for multi-angle positioning of digital camera screens.
