Technical Field

[0001] The utility model relates to the technical field of fasteners for camera pan-tilts, in particular to a high-reliability fastener. Background Art

[0002] A camera pan-tilt is a device used to support and control a camera. It can provide more flexible shooting angles and fields of view. Camera pan-tilts play an important role in modern monitoring and shooting. Selecting a suitable pan-tilt can significantly improve the shooting effect and monitoring quality.

[0003] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: Existing fasteners for camera pan-tilts generally can only fix one type of camera. In working scenarios where cameras need to be frequently replaced, such as professional photography studios or film and television shooting sites, the pan-tilt cannot quickly adapt to cameras of different sizes. Each time a camera is replaced, a large amount of time is required to adjust or replace the pan-tilt, which will seriously affect the continuity of shooting and work efficiency.

[0004] Therefore, the utility model provides a high-reliability fastener. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect in the prior art that in working scenarios where cameras need to be frequently replaced, the pan-tilt cannot quickly adapt to cameras of different sizes, and each time a camera is replaced, a large amount of time is required to adjust or replace the pan-tilt, thus seriously affecting the shooting work efficiency, and to propose a high-reliability fastener.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A high-reliability fastener includes a first connector. A second connector is rotatably connected inside the first connector. Two rotating shafts are rotatably connected inside the second connector. Fixing structures are provided on the surfaces of the two rotating shafts. The fixing structures include two grooves respectively opened on the surfaces of the two rotating shafts. A lifting block is slidably connected to the inner wall of the groove. A round rod is slidably inserted into the interior of the lifting block. A limiting block is fixedly installed on the surface of the round rod. The surface of the limiting block is fixedly connected to the second connector. A connecting rod is fixedly inserted into the interior of the rotating shaft. An extrusion block is threadedly connected to the arc surface of the connecting rod.

[0007] The effects achieved by the above components are: By setting the fixing structure, cameras of different sizes can be clamped on the camera pan-tilt, which not only improves the adaptability of the camera pan-tilt but also improves the stability of the camera on the camera pan-tilt.

[0008] Preferably, springs are sleeved on the arc surfaces of the two round rods. The two ends of each spring are respectively fixedly connected to the limiting block and the lifting block.

[0009] The effects achieved by the above components are as follows: Under the action of the spring elastic force, the lifting block can slide away from the limiting block, achieving the effect of driving the sliding of the lifting block.

[0010] Preferably, two contact frames are rotatably connected to the surfaces of the two lifting blocks, and the cross-section of the contact frame is in an "L" shape.

[0011] The effects achieved by the above components are as follows: The contact frame can fix the lifting block, making the lifting block unable to slide, achieving the effect of restricting the sliding of the lifting block.

[0012] Preferably, four connecting plates are fixedly installed on the surfaces of the two pressing blocks, and anti-slip patterns are provided on the surfaces of the connecting plates.

[0017] The effects achieved by the above components are as follows: With the help of the bearing frame, the square plate can slide up and down, and the mounting rod can prevent the square plate from sliding out of the surface of the guiding frame downward.

[0018] In summary:

[0019] 1. In the present utility model, when it is necessary to fix the camera on the camera pan-tilt, first place the camera between the two pressing blocks, and then rotate the pressing blocks with the help of the connecting plates. The pressing blocks move toward the camera pan-tilt by means of the thread.

The bolt moves in the direction close to the square plate by means of the thread. After the bolt moves a certain distance, the surface of the bolt presses the balance plate. At this time, the camera pan-tilt is fixed. By setting the lifting structure, the height of the fixed camera pan-tilt can be adjusted so that the camera can adjust its height as needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Referring to Figure 1 as shown, the present utility model provides a technical solution: a highly reliable fastener, including a first connecting piece 1. A second connecting piece 2 is rotatably connected inside the first connecting piece 1. Two rotating shafts 3 are rotatably connected inside the second connecting piece 2. A fixing structure 4 is provided on the surfaces of the two rotating shafts 3. By setting the fixing structure 4, cameras of different sizes can be clamped on the camera pan-tilt, which not only improves the adaptability of the camera pan-tilt but also improves the stability of the camera on the camera pan-tilt. A lifting structure 5 is provided on the surface of the first connecting piece 1. By setting the lifting structure 5, the height of the fixed camera pan-tilt can be adjusted so that the camera can adjust its height as needed.

[0027] Next, the specific settings and functions of its fixing structure 4 and lifting structure 5 will be specifically described.

[0028] Referring to Figure 2 andFigure 3 As shown in the figure, in this embodiment: The fixing structure 4 includes two grooves 44, which are respectively opened on the surfaces of the two rotating shafts 3. A lifting block 45 is slidably connected to the inner wall of the groove 44. A round rod 47 is slidably inserted into the lifting block 45. A limiting block 46 is fixedly installed on the surface of the round rod 47. The surface of the limiting block 46 is fixedly connected to the second connecting member 2. A connecting rod 41 is fixedly inserted into the rotating shaft 3. An extrusion block 42 is threadedly connected to the arc surface of the connecting rod 41. Springs 48 are sleeved on the arc surfaces of the two round rods 47. The two ends of the spring 48 are respectively fixedly connected to the limiting block 46 and the lifting block 45. Under the elastic force of the spring 48, the lifting block 45 can slide in a direction away from the limiting block 46, achieving the effect of driving the lifting block 45 to slide. Two contact frames 49 are rotatably connected to the surfaces of the two lifting blocks 45. The cross-section of the contact frame 49 is in an "L" shape. The contact frame 49 can fix the lifting block 45, making the lifting block 45 unable to slide, achieving the effect of restricting the sliding of the lifting block 45. Four connecting plates 43 are fixedly installed on the surfaces of the two extrusion blocks 42. Anti-slip patterns are provided on the surfaces of the connecting plates 43. The connecting plates 43 can assist in rotating the extrusion blocks 42.

[0029] Referring to Figure 2 and Figure 4 As shown in the figure, specifically, the lifting structure 5 includes a square plate 53. The surface of the square plate 53 is fixedly connected to the first connecting member 1. Two guiding frames 52 are slidably connected to the surface of the square plate 53. A balance plate 51 is fixedly installed on the surfaces of the two guiding frames 52. Two bolts 54 are threadedly connected to the inside of the square plate 53. A bearing frame 55 is fixedly installed on the surface of the square plate 53. An installation rod 56 is fixedly inserted into the two guiding frames 52. With the help of the bearing frame 55, the square plate 53 can slide up and down. The installation rod 56 can prevent the square plate 53 from sliding out of the surface of the guiding frame 52.

[0030] Working principle: When it is necessary to fix the camera on the camera pan / tilt head, first place the camera between the two extrusion blocks 42. Then, rotate the extrusion blocks 42 with the help of the connecting plates 43. The extrusion blocks 42 move in the direction close to the camera pan / tilt head by means of the thread. After the extrusion blocks 42 move a certain distance, the surfaces of the extrusion blocks 42 squeeze into the slots of the camera pan / tilt head. At this time, the camera is fixed on the second connecting member 2. Then, slide the lifting block 45 upward. After the lifting block 45 slides a certain distance, the lifting block 45 slides out of the inner wall of the groove 44. At this time, the rotating shaft 3 can rotate. Then, rotate the contact frame 49. After the contact frame 49 rotates a certain angle, the surface of the contact frame 49 contacts the limiting block 46. At this time, the lifting block 45 cannot slide. By setting the fixing structure 4, cameras of different sizes can be clamped on the camera pan / tilt head, which not only improves the adaptability of the camera pan / tilt head but also improves the stability of the camera on the camera pan / tilt head.

[0031] After the camera pan-tilt is fixed on the wall, slide the square plate 53 with the help of the carrier 55. While the square plate 53 slides, it drives the first connecting piece 1 to slide. While the first connecting piece 1 slides, it drives the second connecting piece 2 to slide. After the second connecting piece 2 slides to the required height, stop sliding the square plate 53. Then rotate the bolt 54. The bolt 54 moves in the direction close to the square plate 53 by means of the thread. After the bolt 54 moves a certain distance, the surface of the bolt 54 presses the balance plate 51. At this time, the camera pan-tilt is fixed. By setting the lifting structure 5, the height of the fixed camera pan-tilt can be adjusted so that the camera can adjust its height as needed.
