DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figures 1 to 4The utility model provides a technical solution: a train voice intercom device, comprising an intercom 1, a button 101 and a speaker 102 arranged on the front side of the intercom 1, a frame 2 is arranged on the front side of the intercom 1, an opening 201 is opened at the bottom of the frame 2, and a transparent observation plate 3 is fixedly embedded in the frame 2. The transparent material allows passengers to still see the position of the button 101 and plays a protective role at the same time; two symmetrically distributed elastic guide components 5 are fixedly connected to the front side wall of the intercom 1, and the elastic guide components 5 are used to guide the frame 2 in a straight line so that the frame 2 can only move in the vertical direction.

[0023] The frame 2 and the transparent observation plate 3 can protect the horn 102 and the button 101, thereby preventing passengers from touching the button 101 and causing unnecessary interference and false alarms.

[0024] Specifically, the elastic guide assembly 5 includes two support blocks 501 fixed to the front side wall of the intercom 1, and a guide rod 502 fixed between the two support blocks 501. Two symmetrically distributed through holes 202 are opened on the top of the frame 2. The upper end of the guide rod 502 passes through the through holes 202. A spring 503 is fixedly connected between the support block 501 located above and the top of the frame 2. The spring 503 is sleeved on the guide rod 502. The through hole 202 is a circular hole shape, and the guide rod 502 is a round rod shape.

[0025] A limit groove 203 is provided on the side wall of the frame 2, and a support block 6 is fixedly connected to the front side wall of the intercom 1. A limit block 8 is rotatably arranged on the top of the support block 6 through a rotating shaft 7. The rotating shaft 7 is rotatably inserted on the support block 6, and the end of the rotating shaft 7 is fixedly connected to the limit block 8. When the frame 2 is locked, one end of the limit block 8 is clamped in the limit groove 203, so that the frame 2 and the transparent observation panel 3 can protect the button 101.

[0026] When it is needed, it is only necessary to rotate the limit block 8 to separate the limit block 8 from the limit groove 203. At this time, the spring 503 will pull the frame 2 to move upward, and the frame 2 will move vertically upward along the guide rod 502. At this time, the transparent observation plate 3 will no longer block the button 101, and the button 101 and the speaker 102 will be exposed, thereby facilitating the operation of the button 101 and direct voice calls with the train staff.

[0027] In addition, the limiting groove 203 is a rectangular groove. When the thickness of the limiting block 8 is slightly smaller than the height of the rectangular groove, it is ensured that the limiting block 8 can be smoothly rotated into the limiting groove 203 .

[0028] A pull block 4 is fixedly connected to the lower edge of the frame 2, which can conveniently pull the frame 2 downward to move the limit groove 203 of the frame 2 to the position of the limit block 8. By rotating the limit block 8, the limit block 8 enters the limit groove 203 to lock the position of the frame 2. At this time, the frame 2 and the transparent observation panel 3 protect the button 101.

[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.
