Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a spherical camera for rail transit locomotives. Background Technology

[0002] With the continuous development of electronic surveillance technology and the advancement of science and technology, cameras are used in various places to protect people's safety and interests. Dome cameras are the most common type of camera. Dome cameras are usually installed on walls and ceilings, and their monitoring angle is adjustable.

[0003] A typical dome camera consists of a base, a top cover, and the dome camera itself. The top cover is usually fixed to the base with three screws, and the dome camera itself is pressed between the base and the top cover. When the monitoring angle needs to be adjusted, the three screws must be loosened, and then the dome camera itself must be turned. Once it is adjusted to the appropriate position, the three screws are tightened again. The adjustment is rather cumbersome and needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a spherical camera for rail transit locomotives.

[0005] This utility model is implemented as follows: A spherical camera for rail transit locomotives includes a base, an upper cover, and a spherical camera body. The base is provided with multiple support blocks to support the spherical camera body. The upper cover fixes the spherical camera body to the base from top to bottom. The base is provided with a recessed platform, and the lower part of the upper cover is inserted into the recessed platform. The lower side of the upper cover is provided with an annular groove. A pressure plate is fixed to the base by screws. One end of the pressure plate extends into the annular groove to press the upper cover tightly onto the base. A rubber sleeve is also fitted on the support block to increase the surface friction between it and the spherical camera body.

[0006] The base has a groove for accommodating the pressing sheet, so that the outer surface of the pressing sheet is flush with the outer surface of the base.

[0007] The pressure plate is provided with a waist-shaped hole, and the pressure plate can move inside and outside the waist-shaped hole when the screw is not tightened.

[0008] The upper surface of the tablet is provided with strip-shaped anti-slip texture.

[0009] The base has three support blocks, which are arranged in a ring.

[0010] The inner wall of the settling platform is provided with a protrusion, which is located on the opposite side of the pressing plate and extends into the annular groove from the side.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] As an embodiment of the spherical camera for rail transit locomotives described in this utility model, such as Figures 1 to 6 As shown, the device includes a base 1, an upper pressure cover 2, and a ball-head camera body 3. The base 1 is provided with multiple support blocks 11 to support the ball-head camera body 3. The upper pressure cover 2 fixes the ball-head camera body 3 to the base 1 from top to bottom. The base 1 is provided with a recessed platform 12. The lower part of the upper pressure cover 2 is inserted into the recessed platform 12. The lower side of the upper pressure cover 2 is provided with an annular groove 21. A pressure plate 4 is fixed to the base 1 by screws 5. One end of the pressure plate 4 extends into the annular groove 21 to press the upper pressure cover 2 tightly onto the base 1. A rubber sleeve 6 is also fitted on the support block 11 to increase the surface friction between it and the ball-head camera body 3.

[0024] In this embodiment, the base 1 has three support blocks 11, which are evenly arranged in a ring. This provides multi-point uniform support for the ball-head camera body 3, ensuring the positional stability of the ball-head camera body 3.

[0025] The spherical camera of this application has a recessed platform 12 on its base 1. The lower part of the upper pressure cover 2 is inserted into the recessed platform 12, thereby achieving radial positioning of the upper pressure cover 2. Then, the pressure plate 4 is used to press the upper pressure cover 2 to achieve axial positioning of the upper pressure cover 2. Only one screw 5 is needed to completely fix the upper pressure cover 2. The spherical camera body 3 is pressed between the base 1 and the upper pressure cover 2. When it is necessary to adjust the monitoring angle, the screw 5 is loosened, and the spherical camera body 3 can be rotated. After adjustment, the screw 5 is tightened again, making adjustment more convenient. An annular groove 21 is provided on the lower side of the upper pressure cover 2. One end of the pressure plate 4 extends into the annular groove 21 to prevent the upper pressure cover 2 from coming out and pressing against the base 1. In addition, a rubber sleeve 6 is also fitted on the support block 11 to increase the surface friction between it and the spherical camera body 3. After the screw 5 is tightened, it is not easy to twist the spherical camera body 3 with external force, ensuring the stability of the monitoring angle.

[0026] In this embodiment, refer to Figure 4 The base 1 is provided with a groove 13 for accommodating the pressure plate 4, so that the outer surface of the pressure plate 4 is flush with the outer surface of the base 1, thus ensuring the aesthetic appearance of the entire surveillance camera.

[0027] In this embodiment, refer to Figure 5 The pressure plate 4 has an oblong hole 41, allowing it to move in and out along the oblong hole 41 when the screw 5 is not tightened. The pressure plate 4 can be pulled outwards without fully unscrewing the screw 5, without affecting the adjustment of the upper pressure cover 2 or even its removal, thus preventing the pressure plate 4 from being lost. The upper surface of the pressure plate 4 has striped anti-slip texture 42, allowing users to easily push the pressure plate 4 outwards with their fingers without the need for tools.

[0028] In this embodiment, refer to Figure 4 The inner wall of the sinking platform 12 is also provided with two protrusions 14. The protrusions 14 are located on the other side opposite to the pressure plate 4. The protrusions 14 extend into the annular groove 21 from the side, which can further prevent the other side of the upper pressure cover 2 from tilting up.

[0029] In this embodiment, refer to Figure 6The ball-head camera body 3 includes a front housing 31, a rear housing 32, a camera assembly 33, a fill light plate 34, and a transparent window 35. The camera assembly 33 is disposed between the front housing 31 and the rear housing 32. A partition 311 is provided in the middle of the front housing 31, the fill light plate 34 is disposed outside the partition 311, and the transparent window 35 is disposed on the front housing 31. Since both the fill light plate 34 and the camera assembly 33 generate a large amount of heat, the partition 311 is used to separate them to avoid heat accumulation and to facilitate the rapid transfer of heat from the fill light plate 34 to the front housing 31, from which it is dissipated. Furthermore, the camera assembly 33 includes a camera body 331, an image processing chip 332, a first circuit board 333, and a second circuit board 334. The camera body 331 is disposed on the first circuit board 333, which is fixed to the front housing 31. The image processing chip 332 is disposed on the second circuit board 334, which is disposed on the rear housing 32. The image processing chip 332, which generates the most heat in the camera assembly 33, is configured in this way so that the heat generated by the image processing chip 332 can be quickly transferred to the rear housing 32 and dissipated from the surface of the rear housing 32, thereby improving the heat dissipation effect and reducing the impact of high temperature on the camera body 331.

[0030] In this embodiment, refer to Figure 2 The front housing 31 is also equipped with a microphone 7 for picking up ambient sounds. The microphone 7 is electrically connected to the camera assembly 33 via a cable.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
