[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a video monitoring device for trains which is easy to adjust, such as Figure 1-Figure 4 As shown, it includes a shell 1, a mounting plate 2 is arranged on the back of the shell 1, a hanging plate 21 is arranged on the top of the mounting plate 2, the mounting plate 2 is connected to the shell 1 through a connecting piece 22, the shell 1 is rotated relative to the mounting plate 2 to adjust the angle through the connecting piece 22, and is guided by an adjusting piece 23, the adjusting piece 23 and the connecting piece 22 can be rotated to lock and fix the shell 1 relative to the mounting plate 2, and a lens 11 is installed on the front of the shell 1 for shooting operations.

[0024] In this embodiment, a plurality of hanging holes 211 are provided on the surface of the hanging plate 21 , and the hanging plate 21 and the mounting plate 2 are an integrally formed structure, thereby improving the strength of the entire hanging plate 21 .

[0025] Specifically, the mounting plate 2 is a U-shaped structure and is disposed on the back of the housing 1 to facilitate positioning and protection of the housing 1 .

[0026] Furthermore, one end of the connecting member 22 is provided with an external thread, the outer wall of the mounting plate 2 is provided with a locking hole 13 near the connecting member 22, the inner wall of the locking hole 13 is provided with an internal thread, the connecting member 22 is threadedly connected to the locking hole 13, and the outer end of the connecting member 22 is connected to a pressure plate, which abuts against the outer wall of the mounting plate 2.

[0027] Furthermore, an adjusting groove 12 is provided on the outer wall of the shell 1 near the adjusting member 23. The adjusting groove 12 is an arc-shaped structure. The node 23 slides with the adjusting groove 12. The adjusting member 23 includes a threaded rod 231. A threaded hole 25 is provided on the mounting plate 2 near the threaded rod 231. The threaded rod 231 is threadedly connected with the threaded hole 25. An extrusion head 232 is installed at the end of the threaded rod 231. An elastic gasket 24 is sleeved on the outer side of the extrusion head 232.

[0028] Furthermore, a handle 233 is installed at the outer end of the threaded rod 231 to facilitate the screwing operation of the threaded rod 231 .

[0029] Furthermore, the extrusion head 232 is a truncated cone structure with an inclined outer wall. The inner wall of the elastic gasket 24 is a truncated cone cavity structure close to the extrusion head 232 and its size is adapted to the extrusion head 232. The inner wall of the elastic gasket 24 is a cylindrical cavity structure away from the extrusion head 232. The elastic gasket 24 squeezes the inner wall of the adjusting groove 12 to fix the outer shell 1 and the mounting plate 2, thereby ensuring the locking of the outer shell 1 so that its angle does not change.

[0030] Furthermore, a plurality of interfaces 14 are provided on the back of the housing 1 to facilitate connection of power supply and data transmission.

[0031] When the conveniently adjustable train video surveillance device of the utility model is used, the device is first installed at a suitable position in the train by hoisting or fixing through the hoisting hole 211 on the hanging plate 21. Since the hanging plate 21 and the mounting plate 2 are an integrally formed structure, the strength of the overall structure is improved, ensuring the stability and safety of the installation.

[0032] After installation, the angle of the housing 1 relative to the mounting plate 2 is preliminarily adjusted so that the lens 11 is aimed at the area to be monitored. At this time, the housing 1 can rotate freely within a certain range under the action of the connecting piece 22, which is convenient for flexible adjustment. When the angle of the housing 1 is adjusted to a suitable position, the adjusting piece 23 is used to fix and lock it. By rotating the threaded rod 231 (with a handle 233), the extrusion head 232 slides along the adjustment chute 12 (arc structure) and gradually approaches the inner wall of the adjustment chute 12. The truncated cone structure of the extrusion head 232 and the inclined surface design of its outer wall, combined with the truncated cone cavity structure of the elastic washer 24, enables the extrusion head 232 to gradually compress the elastic washer 24 when the threaded rod 231 rotates, thereby making the cylindrical cavity structure part of the elastic washer 24 fit tightly on the inner wall of the adjustment chute 12, thereby achieving a firm fixation between the housing 1 and the mounting plate 2. The connecting piece 22 is threadedly connected to the locking hole 13 (with internal threads) on the outer wall of the mounting plate 2 through its external threads, further strengthening the connection strength between the housing 1 and the mounting plate 2, ensuring that the angle of the housing 1 does not change after being fixed.

[0033] After the fixing and locking are completed, the lens 11 can be used for shooting and transmit the video data to the monitoring center or other receiving equipment in the train. The interface 14 on the back of the housing 1 is convenient for connecting the power supply and transmitting the data, ensuring the continuous operation of the device and the real-time transmission of the data. If the angle of the housing 1 needs to be adjusted again, it is only necessary to rotate the threaded rod 231 in the opposite direction so that the extrusion head 232 and the elastic washer 24 gradually release the extrusion on the adjustment slide 12, and then readjust the angle of the housing 1 and repeat the above fixing and locking process.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
