Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway auxiliary equipment technology, specifically a subway monitoring device. Background Technology
[0002] Surveillance equipment mainly consists of two parts: front-end equipment and back-end equipment. The front-end typically comprises cameras, manual or motorized lenses, pan-tilt units, protective housings, alarm detectors, and multi-functional decoders. Although these devices may not be used simultaneously in a real surveillance system, cameras and lenses are essential for capturing images of the monitored area. With increasing emphasis on security in public places, surveillance equipment is almost always required. Subways, in particular, are indispensable due to their high passenger volume and stringent security requirements. However, the complex underground structure and high passenger volume of subways make the installation environment for surveillance devices complex, requiring a large number of units and presenting installation challenges. It is impossible to adjust the installation location of surveillance devices to suit various environments. Utility Model Content

[0018] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a subway monitoring device, including a mounting base 1, a bracket 2 rotatably connected to the mounting base 1, a locking member 3 for fixing the bracket 2 and the mounting base 1 at the connection between the bracket 2 and the mounting base 1, a mounting shell 4 rotatably connected to the bracket 2, a limiting member 5 for fixing the bracket 2 and the mounting shell 4 at the connection between the bracket 2 and the mounting shell 4, the rotatable connecting shafts of the bracket 2 and the mounting base 1 and the bracket 2 and the mounting shell 4 are perpendicular or can be arranged at an angle, the mounting shell 4 has mounting holes 6, the mounting shell 4 is detachably fixed to a camera 7 through one of the mounting holes 6, the position of the camera 7 can be adjusted by rotating the bracket 2 and the mounting shell 4 to suit different installation environments, after the bracket 2 rotates, the locking member 3 fixes the bracket 2 to the mounting base 1, after the mounting shell 4 rotates, the limiting member 5 fixes the bracket 2 to the mounting shell 4.
[0020] In one embodiment, the limiting member 5 and the locking member 3 are bolts. The limiting member 5 is threadedly connected to the bracket 2. The bracket 2 is fixed to the mounting shell 4 by the pressing contact between the limiting member 5 and the mounting shell 4. Loosening the limiting member 5 allows the mounting shell 4 to rotate relative to the bracket 2. The locking member 3 is threadedly connected to the bracket 2. The bracket 2 is fixed to the mounting base 1 by the pressing contact between the locking member 3 and the mounting base 1. Loosening the locking member 3 allows the bracket 2 to rotate relative to the mounting base 1. The number of limiting members 5 and locking members 3 can be a suitable number, such as two or four.
[0021] In one embodiment, a portion of each mounting hole 6 is located at both ends of the mounting shell 4. The difference between the rotation axis of the mounting shell 4 relative to the bracket 2 and the distance between the two ends of the mounting shell 4 is greater than zero. The distance between the rotation axis of the mounting shell 4 relative to the bracket 2 and the left end of the mounting shell 4 is much smaller than the distance between the rotation axis of the mounting shell 4 and the right end of the mounting shell 4. Mounting holes 6 are provided on the side of the mounting shell 4. The number of mounting holes 6 is a suitable number, such as three, with two located at both ends of the mounting shell 4 and one located on the side of the mounting shell 4. The mounting position of the camera 7 is increased through each mounting hole 6.
[0022] In one embodiment, the camera 7 is bolted to the connecting rod 8. A protruding block 9 is welded to the circumferential side of one end of the connecting rod 8. The number of protruding blocks 9 is suitable, such as two. Each mounting hole 6 includes a circular hole 6.1 for engaging with one end of the connecting rod 8. A through groove 6.2 is formed on the circumferential side of the circular hole 6.1 for each protruding block 9 to pass through. The number of through grooves 6.2 is the same as the number of protruding blocks 9. A groove 10 is formed on the inner side of the mounting shell 4 to engage with each protruding block 9. The number of grooves 10 is the same as the number of protruding blocks 9, or may be greater. The connecting rod 8 is threaded to an end cover 11. The end cover 11 is press-fitted with the outer side of the mounting shell 4. In use, one end of the connecting rod 8 passes through... After mounting hole 6, rotate it by a certain angle, such as 90°, and then pull the connecting rod 8 outward so that the protrusion 9 and the groove 10 cooperate. By rotating the end cover 11 relative to the connecting rod 8, the end cover 11 moves towards the mounting shell 4 until the end cover 11 applies a certain pressure to the mounting shell 4. At this time, a part of the mounting shell 4 is located between the end cover 11 and the protrusion 9. Through the cooperation of the end cover 11, the protrusion 9 and the mounting shell 4, the connecting rod 8 is fixedly connected to the mounting shell 4. The above process is reversed so that the connecting rod 8 can be removed from the mounting shell 4, so that the connecting rod 8 and the mounting shell 4 are detachably fixedly connected. This makes it easy to install and remove the camera 7.
[0023] In one embodiment, the end cover 11 covers the mounting hole 6, and a sealing ring 12 is installed at the connection between the end cover 11 and the mounting shell 4. The sealing ring 12 is bonded and fixed to the end cover 11, and the sealing ring 12 facilitates the sealing of the mounting hole 6 connected to the connecting rod 8.
[0024] In one embodiment, an annular block 13 is provided on the outer side of the mounting shell 4. The annular block 13 and the mounting shell 4 are integral structures. Each mounting hole 6 is located in each annular block 13. Each annular block 13 is threadedly connected to an end cap 14. When the connecting rod 8 contacts one mounting hole 6, the threaded end cap 14 of each annular block 13 located at the remaining mounting holes 6 is connected to facilitate the sealing of each mounting hole 6 on the shell.
[0025] In one embodiment, through holes 15 are provided on the mounting base 1. The number of through holes 15 is a suitable number, such as six. The through holes 15 are evenly distributed in a ring on the mounting base 1, and the mounting base 1 is easily fixed through the through holes 15.
[0026] In one embodiment, the mounting base 1 includes a base plate on which a disc is bolted. The disc is formed by two coaxial cylindrical blocks with different inner diameters. A through hole 15 is provided on the base plate, and the disc is rotatably connected to the bracket 2.
[0027] In one embodiment, the bracket 2 includes an annular sleeve, which is rotatably connected to the mounting base 1. Support plates are installed on both sides of the annular sleeve, and the mounting shell 4 is located between the two support plates and rotatably connected to the support plates. All parts of the bracket 2 are integral structures.
[0028] In one embodiment, the mounting shell 4 is a box-shaped structure such as a cuboid, and the box-shaped structure has a cavity inside.
[0029] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the present invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the present invention, and these should also be considered within the scope of protection of the present invention.
