[0002] In the installation and use of fixed cameras (such as in security monitoring applications), precise adjustment of the camera's tilt and rotation angles is crucial to ensuring optimal coverage of the shooting angle. Current technologies primarily rely on pan-tilt mechanisms or simple brackets for camera angle adjustment, but these have significant drawbacks in practical use.
[0003] Traditional gimbals or simple stands can adjust the horizontal rotation and pitch angles, but the adjustment range is limited. The horizontal rotation and pitch angles can only be adjusted within a specific range of 90 degrees. Beyond the 90-degree range, the angles cannot be adjusted. Moreover, existing gimbals or simple stands lack limiting measures after angle adjustment. After the angle is adjusted, it is easily affected by vibration or other factors, which can cause the preset angle to loosen and change. Utility Model Content

[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0034] like Figures 1-10 The illustrated dual-degree-of-freedom lockable camera device adjustment and fixing device includes: a camera device 1, a mounting arm 5, and a mounting base 6. The mounting arm 5 and the mounting base 6 are fixedly connected by welding. The mounting base 6 has paired threaded holes, which are used to connect the entire device to the designated monitoring position via bolts. The mounting arm 5 has a base 4, a horizontal adjustment seat 3, and a pitch adjustment frame 2 arranged longitudinally. The mounting arm 5 and the base 4 are fixedly connected by bolts. The horizontal adjustment seat 3 is rotatably connected to the base 4. The base 4 has evenly spaced base adjustment and fixing holes 1 in the circumferential direction. 6. Horizontal adjustment holes 14 are evenly provided in the circumferential direction of the horizontal adjustment seat 3. The base adjustment fixing hole 16 is connected to the horizontal adjustment hole 14 by bolts. A pitch ear plate 8 is welded on the horizontal adjustment seat 3. The pitch adjustment frame 2 is hinged on the pitch ear plate 8. Pitch guide adjustment holes 11 are also evenly provided in a 180-degree pattern on the pitch adjustment frame 2. The pitch guide adjustment holes 11 are distributed in a semi-circular arc shape. A guide fixing hole 13 is also provided on the pitch ear plate 8. The pitch guide adjustment hole 11 and the guide fixing hole 13 are connected by bolts. The camera equipment 1 is fixedly connected to the pitch adjustment frame 2.
[0035] The aforementioned dual-degree-of-freedom lockable camera adjustment and fixing device is rotatably connected to the horizontal adjustment seat 3 via the base 4. It also features a horizontal adjustment hole 14 and a base adjustment fixing hole 16, allowing the camera 1 to adjust a specific horizontal camera angle within a 360-degree range. The base adjustment fixing hole 16 and the horizontal adjustment hole 14 are connected by bolts to form a limit, preventing loosening and angle changes. The pitch adjustment frame 2 is hinged to the pitch ear plate 8, and pitch guide adjustment holes 11 are evenly spaced at 180-degree intervals on the pitch adjustment frame 2, ensuring that the camera 1 can adjust a specific pitch camera angle within a 180-degree range. The pitch guide adjustment hole 11 and the guide fixing hole 13 are connected by bolts to form a limit, preventing loosening and angle changes.
[0036] like Figures 1-5As shown, in this embodiment, the pitch adjustment frame 2 is provided with camera equipment mounting holes 9, and the camera equipment 1 is connected to the pitch adjustment frame 2 through the camera equipment mounting holes 9. The camera equipment mounting holes 9 are provided in pairs, and the camera equipment 1 is fixedly installed on the pitch adjustment frame 2 by bolts or anti-loosening stainless steel screws, so as to achieve a stable installation of the camera equipment 1.
[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in this embodiment, the pitch ear plate 8 has a pitch connection hole 12, and the pitch adjustment frame 2 has a pitch center hole 10. The pitch center hole 10 and the pitch connection hole 12 are connected by bolts. The bolts can be column bolts or rod bolts. The hinged installation is achieved by simultaneously passing through the pitch center hole 10 and the pitch connection hole 12. By connecting the pitch center hole 10 and the pitch connection hole 12 with bolts, the pitch adjustment frame 2 can rotate and adjust its pitch angle relative to the pitch ear plate 8, thereby adjusting the pitch angle of the camera device 1 and improving the camera's position. The viewing angle range is defined, and the pitch guide adjustment hole 11 and the guide fixing hole 13 are also fixedly connected by bolts to form a limit to prevent loosening and angle changes. Since multiple pitch guide adjustment holes 11 are evenly opened at 180 degrees, each pitch guide adjustment hole 11 corresponds to a specific pitch angle within the 180-degree range, that is, the pitch angle can be adjusted within ±90 degrees. Therefore, the corresponding pitch guide adjustment hole 11 can be selected during the adjustment process. In addition, the number of pitch guide adjustment holes 11 can be opened according to the actual angle adjustment requirements.
[0038] like Figure 1 , Figure 6 , Figure 8 and Figure 10As shown, in this embodiment, both the base adjustment fixing hole 16 and the horizontal adjustment hole 14 are oblong holes. The horizontal adjustment seat 3 and the base 4 are rotatably connected, allowing them to rotate relative to each other within a 360-degree range. At the same time, the base adjustment fixing hole 16 and the horizontal adjustment hole 14 are aligned vertically. The oblong hole design facilitates vertical alignment and allows for the installation of anti-loosening bolts to limit and lock the horizontal rotation angle. Due to the presence of the base adjustment fixing hole 16 and the horizontal adjustment hole 14, the camera device 1 can be fixed and adjusted at a specific angle within a 360-degree range. Each pair of base adjustment fixing holes 16 and the horizontal adjustment hole 14 corresponds to a specific horizontal rotation angle. Therefore, during the adjustment process, the corresponding base adjustment fixing hole 16 and the horizontal adjustment hole 14 can be selected. In this embodiment, twelve pairs of base adjustment fixing holes 16 and the horizontal adjustment hole 14 are provided. In addition, the number can be adjusted according to the actual angle adjustment needs.
[0039] like Figure 1 , Figure 6 , Figure 8 and Figure 10 As shown, in this embodiment, the horizontal adjustment seat 3 is provided with a horizontal adjustment fixing hole 7, and the base 4 is provided with a base fixing hole 15. The horizontal adjustment fixing hole 7 and the base fixing hole 15 are connected by bolts. Anti-loosening bolts are selected to fix the horizontal adjustment seat 3 and the base 4, thereby ensuring the stable installation of the camera equipment 1.
[0040] like Figures 1-10 As shown, in this embodiment, the diameters of the horizontal adjustment fixing hole 7 and the base fixing hole 15 are both 5mm. The horizontal adjustment fixing hole 7 and the base fixing hole 15 can be adjusted according to the size of the anti-loosening bolt. The cross-sectional diameters of the horizontal adjustment seat 3 and the base 4 are both 60mm, and the cross-sectional dimensions of the horizontal adjustment seat 3 and the base 4 are the same, thereby ensuring that they can completely overlap and that the base adjustment fixing hole 16 and the horizontal adjustment hole 14 can be aligned to achieve the purpose of locking and limiting after angle adjustment. The thickness of the horizontal adjustment seat 3 is 1mm. The thickness of the horizontal adjustment seat 3 can be adjusted according to the actual situation. Adjustments are made accordingly, but since the pitch ear plate 8 is welded to the horizontal adjustment seat 3, the thickness of the horizontal adjustment seat 3 must meet the welding requirements. The diameter of the pitch guide adjustment hole 11 is 4mm, and the length of the pitch adjustment frame 2 is 70mm. The device is small in size, so it occupies less space and can be installed in some places with limited space, which improves the flexibility of the device. It is suitable for video surveillance, security and credit collateral supervision and other fields. At the same time, the base 4 is made of precision die-cast zinc alloy matrix, which is lightweight, thus improving the lightweight design of the entire device.
[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, in this embodiment, the camera device 1 is first fixedly installed onto the pitch adjustment frame 2 using bolts or anti-loosening stainless steel screws. The pitch center hole 10 and the pitch connection hole 12 are then connected using column or rod bolts. Next, the pitch adjustment frame 2 is adjusted to a specific angle, and the pitch guide adjustment hole 11 and guide fixing hole 13 are fixedly connected using bolts to lock the angle. Then, the horizontal rotation angle of the camera device 1 is adjusted, and the horizontal adjustment seat 3 is connected to the base 4. The base adjustment fixing hole 16 is aligned with the horizontal adjustment hole 14 and fixed using anti-loosening bolts to achieve limit locking. This installation method effectively ensures reliable positioning and overall rigidity between the components of the device. By using the pitch angle... The dual adjustment mechanism of angle adjustment and horizontal rotation angle adjustment enables dual-degree-of-freedom adjustment. Moreover, the modular design of each component allows for independent replacement and disassembly, facilitating later maintenance and upgrades. All fasteners are made of stainless steel to ensure long-term stability, improve connection strength and service life, making the device suitable for security monitoring. It is not only easy to adjust but also has a firm connection and angle locking, achieving a high-stability locking mechanism with anti-human interference characteristics. The adjustment range is 40% larger than that of traditional pan-tilt structures, avoiding the existence of blind spots in narrow corridors or panoramic monitoring scenarios. It is also unaffected by long-term exposure to vibration environments, such as wind loads, equipment vibration causing loosening, and angle changes.
[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
