[0002] Bullet cameras are a type of camera suitable for areas with insufficient light or where lighting equipment cannot be installed at night. They are currently widely used in the security field. With the development of applications, various brackets have been developed for bullet cameras. Depending on the application scenario, the bracket can be manually adjusted to support 360° installation of the camera. Current equipment brackets generally use a screw-loosening method for manual adjustment. Due to mold opening limitations, most common bracket structures on the market use... Figure 1 The four structural components shown in Figures AD, when fixed to the bolt housing, achieve 360-degree angle adjustment, but these components are costly. During assembly, structural components B and C on the left and right sides need to be fixed to structural component A using two extended screws. Because wiring is involved, one of the fastening screws must be avoided, making assembly cumbersome. Furthermore, when adjusting the angle by loosening the fastening screws, structural components B and C separate too much, making adjustment inconvenient. Utility Model Content

[0027] 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 scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] Reference Figures 2-3 This utility model provides a camera 9 adjustment device, including a base 1, a rotating cylinder 2, a first rotating shaft, a first fixing member, and an angle adjustment bracket 3. One end of the rotating cylinder 2 is rotatably mounted on the base 1. The first rotating shaft passes through the side wall of the rotating cylinder 2 and is inserted into the rotating cylinder 2. The angle adjustment bracket 3 is mounted on the end of the rotating cylinder 2 away from the base 1 and is rotatably connected to the first rotating shaft. The rotating cylinder 2 has an clearance opening on the rotation path of the angle adjustment bracket 3. The first fixing member is used to fix the relative position of the angle adjustment bracket 3 and the rotating cylinder 2. In use, the camera 9 is mounted on the angle adjustment bracket 3, and the horizontal position is adjusted by rotating the rotating cylinder 2, causing the angle adjustment bracket 3 to rotate around the first rotating shaft, changing the angle of the camera 9. The first fixing member is used to achieve arbitrary angle suspension adjustment of the camera 9.

[0031] Specifically, the first rotating shaft includes a first screw 4; the rotating cylinder 2 has a first threaded hole 201; the angle adjusting bracket 3 has a first mounting hole 301, and the diameter of the first mounting hole 301 is larger than the diameter of the first screw 4; the first screw 4 is threadedly connected to the first threaded hole 201 and inserted into the first mounting hole 301. The first screw 4 is fixed to the rotating cylinder 2 through the first threaded hole 201. Since the first mounting hole 301 has no threads and its diameter is larger than that of the first screw 4, the portion of the first screw 4 inserted into the first mounting hole 301 can serve as a rotating shaft, allowing the angle adjusting bracket 3 to rotate around it. During adjustment, the first fixing member is first released, allowing the angle adjusting bracket 3 to rotate around the first rotating shaft to a suitable position, and then the first fixing member is used to lock it in that position.

[0032] To better control the adjustment angle of the angle adjustment bracket 3, refer to Figures 5-6As shown, a first annular tooth 303 is provided on the outer wall of the angle adjustment bracket 3 around the first mounting hole 301; the inner wall of the rotating cylinder 2 is provided with a limiting tooth 203 that matches the first annular tooth 303, which can prevent the angle adjustment bracket 3 from coming off. Generally, only one matching limiting tooth 203 is designed on the rotating cylinder 2 to facilitate the overall demolding of the rotating cylinder 2. When the limiting tooth 203 is set, there is a certain gap between the angle adjustment bracket 3 and the inner wall of the rotating cylinder 2. When adjustment is required, the fixing effect of the first fixing member is first released, so that the angle adjustment bracket 3 can move relative to the axis of the first screw 4. When the movement exceeds the height of the limiting tooth 203, the angle adjustment bracket 3 can be rotated to a suitable angle. Then, the angle adjustment bracket 3 is moved in the opposite direction so that the limiting tooth 203 is engaged with the corresponding tooth slot of the first annular tooth 303, and the first fixing member is locked to complete the adjustment. In one embodiment, the first annular tooth 303 can be provided with 60 teeth in one circle, and each tooth is an adjustment of 6°, so that the bolt can achieve vertical rotation.

[0033] Furthermore, the first fixing component includes a second screw 5; the rotating drum 2 is provided with a second mounting hole 202; the angle adjusting bracket 3 is provided with a second threaded hole 302; the second screw 5 passes through the second mounting hole 202 and is threadedly connected to the second threaded hole 302. In one embodiment, the second mounting hole 202 can also be a threaded hole, and the rotating drum 2 and the angle adjusting bracket 3 are fixed by the cooperation of the second screw 5, the second mounting hole 202, and the second threaded hole 302. In another embodiment, a limiting protrusion that cooperates with the head of the second screw 5 is provided in the second mounting hole 202 to prevent the rotating drum 2 from rotating relative to the second screw 5. When the angle needs to be adjusted, the second screw 5 is loosened, so that the angle adjusting bracket 3 rotates around the first rotating axis to a suitable position, and the second screw 5 is tightened again to lock the relative position of the angle adjusting bracket 3 and the rotating drum 2. The second threaded hole 302 and the second mounting hole 202 are both opened on the rotation axis of the angle adjusting bracket 3 to avoid the second threaded hole 302 and the second mounting hole 202 being misaligned during adjustment, making it difficult to tighten the second screw 5.

[0034] A first annular tooth 303 can also be provided on the outer wall of the angle adjustment bracket 3 around the second threaded hole 302 to improve the rotational stability of the angle adjustment bracket 3.

[0035] The design of the first screw 4 and the second screw 5 eliminates the need to lengthen a single screw to tighten the structural components, thus avoiding the impact of internal compression on the power cord 10. This allows for more relaxed and convenient internal routing of the power cord 10, resulting in higher reliability. Adjusting the angle also facilitates reassembly, improving efficiency.

[0036] In one detailed embodiment, a second rotating shaft 6 is provided on the base 1; the rotating cylinder 2 is rotatably sleeved on the second rotating shaft 6 and is detachably connected to the second rotating shaft 6 by a second fixing member 7. During adjustment, the restriction of the second fixing member 7 is released, the rotating cylinder 2 is rotated to a suitable position, and the relative position of the rotating cylinder 2 and the rotating shaft is locked by the second fixing member 7.

[0037] Specifically, the second rotating shaft 6 has a groove; the rotating cylinder 2 has a third threaded hole 205; the second fixing member 7 includes a set screw (flat-end tightening screw); the set screw passes through the third threaded hole 205 and abuts against the groove, locking the rotating cylinder 2 and the base 1. When the position needs to be adjusted, loosen the set screw, rotate the rotating cylinder 2 around the second rotating shaft 6 to the appropriate position, and then tighten the set screw again.

[0038] To better control the rotation angle of drum 2, such as Figures 4-5 As shown, a second annular tooth 101 is provided on the base 1 around the second rotating shaft 6; the end of the rotating cylinder 2 connected to the base 1 is provided with a third annular tooth 204 that matches the second annular tooth 101; the second annular tooth 101 and the third annular tooth 204 are toothed together. The number of teeth in the second annular tooth 101 and the third annular tooth 204 is generally between 30 and 60, which can precisely adjust the angle of the rotating cylinder 2. During adjustment, the restriction of the second fixing member 7 is released, and the relative position of the second annular tooth 101 and the third annular tooth 204 is changed according to the required angle. After adjusting to the required position, the second fixing member 7 is locked.

[0039] In one embodiment, a through-channel is formed within the angle adjustment bracket 3, the rotating cylinder 2, and the base 1, through which the power cable 10 of the camera 9 is managed. (See reference...) Figure 9 As shown, when rotating, installing, and removing the bracket, the internal wires remain unobstructed and will not be squeezed on the sides by the screws.

[0040] Preferably, the base 1 has an opening on its side that connects to the wiring channel, making it convenient for the wires to pass through the side of the base 1 and avoiding affecting the installation of the base 1.

[0041] In one optimized embodiment, the base 1 is provided with a third fixing member 8 for connection with an external structure. The third fixing member 8 may be an expansion screw, which is used to mount the camera 9 adjustment device to a wall or other location.

[0042] Reference Figures 7-9 This utility model also provides a gun-type camera, including a camera 9 and the aforementioned camera 9 adjustment bracket; the housing of the camera 9 is mounted on the angle adjustment bracket 3 of the camera 9 adjustment device, and the camera 9 is rotated by the angle adjustment bracket 3 to realize the adjustment of the camera 9.

[0043] In a more detailed embodiment, a groove can also be provided at the end of the angle adjustment bracket 3 away from the rotating cylinder 2. The housing of the camera 9 has a threaded hole, and the threaded hole of the set screw abuts against the groove, pressing the angle adjustment bracket 3 and the housing of the camera 9 together. The groove allows the angle adjustment bracket 3 and the housing to rotate horizontally without angular limitation.
