DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 3The utility model provides a technical solution: a subway car media device, including a display screen 1, a positioning block 5 fixed to the rear side wall of the display screen 1, and a bottom shell 6 located below the positioning block 5. A groove 601 is opened on the top of the bottom shell 6. The lower end of the positioning block 5 is rotatably inserted into the bottom wall of the groove 601. A turntable 9 is fixedly connected to the rotating shaft 8. The circumferential surface of the turntable 9 is provided with arc-shaped grooves 901 distributed at equal distances. A clamping assembly 10 matching the arc-shaped grooves 901 is arranged inside the groove 601. The clamping assembly 10 locks the angle of the turntable 9.

[0022] Since the rotating shaft 8 is rotatably inserted inside the bottom shell 6, the user can rotate the display screen 1, which is convenient for passengers to observe when they are located at the side and improves the visibility of the display screen 1; and the angle of the turntable 9 can be locked through the snap-fit ​​assembly 10, thereby locking the angle of the display screen 1.

[0023] Specifically, the clamping assembly 10 includes a base block 1002 fixed to the inner wall of the groove 601, and two pins 1004 are movably inserted inside the base block 1002. The pins 1004 realize the purpose of linear guidance of the arc-shaped clamping block 1001. The other end of the pins 1004 is fixedly connected with the arc-shaped clamping block 1001. The arc-shaped clamping block 1001 is clamped in the arc-shaped slot 901, and a spring 1003 is fixedly connected between the end of the pin 1004 and the base block 1002.

[0024] The latch pin 1004 is in the shape of a round rod, and the spring 1003 is sleeved on the latch pin 1004 .

[0025] During the process of rotating the display screen 1, the rotating shaft 8 and the turntable 9 rotate synchronously. When the arc-shaped end of the arc-shaped clamping block 1001 corresponds to the position of the arc-shaped clamping groove 901, the spring 1003 releases its elastic force, pushing the latch 1004 and the arc-shaped clamping block 1001 to move, and finally the arc-shaped clamping block 1001 is clamped in the arc-shaped clamping groove 901, thereby locking the turntable 9.

[0026] The rear end of the bottom shell 6 is fixedly connected with a baffle 7, which is provided with rectangular mounting holes 701. Fasteners are arranged inside the mounting holes 701 so that the baffle 7 is fixedly mounted to the inner wall of the subway car through the fasteners.

[0027] In addition, side guard plates 2 are fixedly installed on both sides of the display screen 1 by first bolts 4. The side guard plates 2 are L-shaped as a whole. Rubber pads 3 are fixedly connected to the surface of the side guard plates 2. The rubber pads 3 are used to reduce wear when in contact with the subway car.

[0028] The edge of the display screen 1 can be protected by the side guard plate 2 and the rubber pad 3. When the display screen 1 is rotating, the edge of the display screen 1 may come into contact with the subway car, and the rubber pad 3 directly contacts the inner wall of the car. The rubber pad 3 can reduce the wear on the inner wall of the car and the outer shell of the display screen 1.

[0029] 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.
