Description

Technical Field

[0001] This application relates to the technical field of shooting focus, and in particular to a dual-axis sliding rail focus device. Background Technology

[0002] In daily shooting, it is necessary to focus on moving people or objects. To facilitate shooting, the camera equipment is fixed on a gimbal, and the focus on moving people or objects is achieved by driving the gimbal to move.

[0003] The existing patent application number CN202320828590.1 is a flywheel electric focus slider device, which includes a slider assembly, a movable slider, a gimbal scale, a rotating linkage, an angle adjustment rod, and a scale adjustment knob. The movable slider slides on the slider assembly, the gimbal scale is rotatably connected to the movable slider, the scale adjustment knob is located at both ends of the angle adjustment rod and slides at both ends of the slider assembly, the rotating linkage is slidably connected to the angle adjustment rod, and the rotating linkage can drive the gimbal scale to rotate. When the movable slider moves on the slider assembly, the photographic equipment on the movable slider slides accordingly. By adjusting the position of the scale adjustment knob, the position of the angle adjustment rod is adjusted, thereby adjusting the angle of the rotating gimbal scale on the movable slider, realizing the function of adjusting the shooting angle.

[0004] In this patent, the angle of the gimbal dial can only be adjusted in advance, and then the shooting angle is continuously moved to follow the focus. If the person or object rotates during the shooting and focusing process, the shooting angle also needs to rotate accordingly, which this patent cannot do. Therefore, the existing technology cannot meet the shooting and focusing requirements of moving and rotating at the same time. Utility Model Content

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application provides a dual-axis sliding rail focusing device, which can solve the problem in related technologies that cannot meet the requirements of simultaneous moving and rotating shooting and focusing.

[0020] Please see Figures 1 to 7 A dual-axis slide rail focusing device includes: a frame 1, a first component 2, a second component 3, and a translation carrier 4. The first component 2 includes a first slide rail 21, which is fixedly connected to the frame 1. The second component 3 includes a second slide rail 31, with its two ends slidably connected to opposite ends of the frame 1. Both the first slide rail 21 and the second slide rail 31 extend from one end of the frame 1 to the opposite end of the frame 1. The translation carrier 4 is slidably connected to the first slide rail 21. A rotating carrier 5 is provided on the translation carrier 4. The rotating carrier 5 includes a gimbal 51 and a rotating component 52. The gimbal 51 is rotatably connected to the translation carrier 4. One end of the rotating component 52 is fixedly connected to the gimbal 51, and the other end of the rotating component 52 is slidably connected to the second slide rail 31. In this embodiment, the frame 1 includes a mounting component 11 and a control component 12, such as... Figure 1 As shown, the mounting component 11 is located on the left and right sides of the control component 12. The two ends of the first slide rail 21 extend to the two ends of the control component 12, and the first slide rail 21 is located on the upper and lower sides of the control component 12 respectively. While ensuring that the translation carrier 4 moves along the first slide rail 21, the space of the frame 1 is effectively utilized. One end of the second slide rail 31 is located on one of the mounting components 11, and the other end of the second slide rail 31 is located on the control component 12 away from the mounting component 11 on which the second slide rail 31 is mounted. The two ends of the second slide rail 31 rise and fall, so that the second slide rail 31 tilts relative to the first slide rail 21. When the translation carrier 4 moves along the first slide rail 21, the rotating component 52 will also move along the second slide rail 31. The tilt of the second slide rail 31 causes the rotating component 52 to rotate relative to the translation carrier 4, thereby driving the gimbal 51 to rotate on the translation carrier 4. This realizes that when the translation carrier 4 moves, the gimbal 51 rotates on it, which meets the requirements of shooting and focusing while moving and rotating.

[0021] Furthermore, in this embodiment, the second component 3 also includes a first limiting frame 32, a second limiting frame 33, and a hinge 34. The first limiting frame 32, the second limiting frame 33, and the hinge 34 are all fixedly connected to the frame 1, and the hinge 34 is located between the first limiting frame 32 and the second limiting frame 33. The second slide rail 31 is rotatably connected to the hinge 34. One end of the second slide rail 31 is located inside the first limiting frame 32, and the other end of the second slide rail 31 is located inside the second limiting frame 33. The first limiting frame 32 consists of two protrusions and a horizontal plate. The protrusions are integrally set with the mounting piece 11 on one side. One end of the second slide rail 31 moves between the two protrusions, the horizontal plate, and the mounting piece 11. When the second slide rail 31 rotates on the hinge 34, the movement paths of both ends of the second slide rail 31 are arc-shaped, such as... Figure 7 As shown, the second limiting frame 33 is fixedly connected to the control component 12. The second limiting frame 33 has an arc-shaped hole in the middle, which facilitates the installation of one end of the second slide rail 31 on the arc-shaped hole, thereby limiting the rotation angle of the second slide rail 31.

[0022] Furthermore, in this embodiment, the second component 3 also includes a handle 35 and a boss 36. The handle 35 is eccentrically hinged to one end of the second slide rail 31, and the boss 36 is fixedly connected to the frame 1. The handle 35 has a fixed position. When the handle 35 is in the fixed position, the handle 35 abuts against the boss 36. When the handle 35 is not in a fixed position, the handle 35 does not contact the boss 36. At this time, the second slide rail 31 can freely adjust the rotation angle. After the adjustment is completed, rotate the handle 35, and the handle 35 abuts against the boss 36. The friction force restricts the rotation of the second slide rail 31. In order to better restrict the rotation of the second slide rail 31, it is necessary to increase the friction force between the handle 35 and the boss 36. Therefore, the handle 35 can be made of rubber.

[0023] To facilitate the installation of camera equipment on the gimbal 51, the gimbal 51 and the rotating component 52 are slidably connected to one end of the second slide rail 31 and are respectively located on opposite sides of the translation carrier 4.

[0024] Specifically, in this embodiment, the second component 3 further includes a first magnetic element 37 and a second magnetic element 38. The first magnetic element 37 is fixedly connected to the frame 1, and the second magnetic element 38 is fixedly connected to the second slide rail 31. The second slide rail 31 has a parallel position. When the second slide rail 31 is in the parallel position, the second slide rail 31 is parallel to the first slide rail 21, and the first magnetic element 37 is attracted to the second magnetic element 38. When the second slide rail 31 and the first slide rail 21 are parallel to each other, since the position of the rotating component 52 relative to the translation carrier 4 remains unchanged, the gimbal 51 will not rotate, thus realizing the two functions of this application: allowing the gimbal 51 to rotate or preventing the gimbal 51 from rotating. It is important to know that if the angle of the second slide rail 31 is adjusted manually, it is easy to cause deviation, which may cause the camera to rotate during the shooting and focusing process. In order to make it easier to adjust the second slide rail 31 to be parallel to the first slide rail 21, a first magnetic component 37 and a second magnetic component 38 are provided. When the second slide rail 31 approaches the first slide rail 21, the first magnetic component 37 and the second magnetic component 38 attract each other, and the second slide rail 31 will automatically move closer to the parallel position until the first magnetic component 37 is directly above the second magnetic component 38. At this time, the second slide rail 31 is parallel to the first slide rail 21.

[0025] More specifically, in this embodiment, the translation carrier 4 includes a movable plate 41 and a mating wheel 42. The mating wheel 42 is disposed on the movable plate 41 and is slidably connected to the first slide rail 21. The movable plate 41 is a square plate, and the mating wheels 42 are installed at the four corners of the movable plate 41, such as... Figure 2 As shown, the two wheels located on the upper or lower side slide on the first slide rail 21 on the same side, ensuring the smooth movement of the moving plate 41.

[0026] The translation carrier 4 also includes a spring 43 and a mounting block 44. The mating wheel 42 is rotatably connected to the mounting block 44. The mounting block 44 is set on the moving plate 41. The spring 43 is located between the mounting block 44 and the moving plate 41. The two ends of the spring 43 abut against the mounting block 44 and the moving plate 41 respectively. The structure of mounting block 44 is as follows: Figure 2 As shown, a movable groove is provided on the mounting block 44, and a bolt is provided on the movable plate 41. The bolt passes through the movable plate 41 to install the mounting block 44 onto the movable plate 41. At the same time, the mounting block 44 can be finely adjusted on the movable plate 41, that is, the mating wheel 42 can move to both sides of the movable plate 41. The spring 43 will continuously provide force to the mounting plate, which will cause the mating wheel 42 to press against the first slide rail 21, ensuring that the mating wheel 42 can move normally on the first slide rail 21. At the same time, when installing the mating wheel 42 onto the first slide rail 21, the operator can bend the mating wheel 42. When the mating wheel 42 is on the first slide rail 21, the mating wheel 42 can be released, and the mating wheel 42 will rest on the first slide rail 21. Compared with the rigid connection between the mating wheel 42 and the movable plate 41, the mating wheel 42 resting on the first slide rail 21 through the spring 43 can make the mating wheel 42 fit the first slide rail 21 more closely, and the installation is more convenient. It should be noted that the gimbal 51 is rotatably connected to the movable plate 41, and one end of the rotating part 52 passes through one side of the movable plate 41 to the other end and is fixedly connected to the gimbal 51.

[0027] In a preferred embodiment, the first component 2 further includes a track 22 and a clamping member 23. The clamping member 23 is fixedly connected to the translation carrier 4, and the track 22 is rotatably connected to the frame 1. The track 22 and the clamping member 23 are detachably connected. Rollers are provided in the mounting members 11 on both sides. The track 22 is sleeved on the two rollers. The track 22 is moved by rotating the rollers, and at the same time, the moving plate 41 and the gimbal 51 on it are moved.
