The outer surfaces of the first rectangular rod 103 and the second rectangular rod 105 are provided with sockets 106, and handles 107 are installed on the outer surfaces of both sides of the mounting base 100. Two inner grooves 108 are provided at both ends of the handle 107 in the length direction. The inner grooves 108 are provided with fixing mechanisms 200 that are plugged with the sockets 106. Since the handle 107 is installed on the radio body 101, when the fixing mechanism 200 on the handle 107 is plugged with the sockets 106 on the first rectangular rod 103 and the second rectangular rod 105, the purpose of installing the radio body 101 on the mounting base 100 and installing the top cover 104 on the radio body 101 can be achieved, making them a whole.

[0022] Mounting blocks 600 are installed on both outer surfaces of the mounting seat 100, and mounting holes 601 are opened inside the mounting blocks 600. Through the setting of the mounting blocks 600 and the mounting holes 601, the mounting seat 100 can be fixed in the car with bolts to provide an installation position for the mounting seat 100.

[0023] The fixing mechanism 200 includes a rod 201 slidably mounted inside the inner groove 108, and the end of the rod 201 is plugged into the socket 106. A first spring 202 is arranged inside the inner groove 108, and the two ends of the first spring 202 are respectively in contact with the inner wall of the inner groove 108 and the rod 201. A through groove 203 is provided on the outer surface of the handle 107 along its length direction. A push rod 204 is installed on the outer surface of the rod 201, and the end of the push rod 204 passes through the through groove 203 and extends to the outside of the handle 107. When the rectangular hollow tube 102 is sleeved on the outside of the first rectangular rod 103 or the second rectangular rod 105 is inserted into the rectangular hollow tube 102, the first spring 202 is in contact with the inner wall of the inner groove 108 and the rod 201. When inserting the rod 201 into the inside of the hollow tube 102, the rod 201 can be directly inserted into the socket 106 on the surface thereof, so as to fix the first rectangular rod 103 or the second rectangular rod 105, and under the thrust of the first spring 202, the rod 201 can be stably inserted into the inside of the socket 106, thereby preventing the rod 201 from being separated from the inside of the socket 106 due to vibration during the running of the train. When the radio body 101 or the top cover 104 needs to be removed, the push rod 204 can be pushed to drive the rod 201 to be pulled out from the inside of the socket 106, and then the radio body 101 or the top cover 104 can be directly lifted up.

A second spring 303 is sleeved on the outer surface of the positioning rod 301, and the two ends of the second spring 303 are respectively abutted against the inner wall of the fixing tube 300 and the shoulder 302. A positioning hole 304 is opened on the outer surface of the insertion rod 201, and the positioning hole 304 is plugged into the positioning rod 301. When the push rod 204 is pushed to drive the insertion rod 201 to be pulled out from the inside of the insertion hole 106, the insertion rod 201 will compress the first spring 202. When the end of the insertion rod 201 is retracted into the inner groove 108 and the positioning hole 304 is in When the positioning rod 301 is directly below the positioning rod 301, under the action of the shoulder 302, it can push the positioning rod 301 to automatically insert into the positioning hole 304, so as to fix the insertion rod 201. At this time, the push rod 204 can be loosened to lift the radio body 101 or the top cover 104 to complete the disassembly. When installing the radio body 101 or the top cover 104, the rectangular empty tube 102 is sleeved on the outside of the first rectangular rod 103 or the second rectangular rod 105 is inserted into the inside of the rectangular empty tube 102, and then the positioning rod 301 is lifted upward to drive its end to be pulled out of the positioning hole 304.

Then, when the positioning hole 304 moves to the position corresponding to the positioning rod 301, under the elastic force of the second spring 303, the positioning rod 301 can be pushed to be inserted into the positioning hole 304 to fix the plug rod 201. Then, the radio body 101 is lifted upward to pull the rectangular empty tube 102 out of the first rectangular rod 103, thereby completing the rapid removal of the radio body 101. Then, the radio body 101 is placed on the maintenance platform, and then the push rod 204 located on the upper side is pushed to drive the plug rod 201 to be pulled out from the socket 106 on the second rectangular rod 105. Then, the positioning rod 301 is inserted into the positioning hole 304 to fix the position of the plug rod 201. Then, the top cover 104 is lifted upward to complete the top cover The quick removal of 104 makes it easy for maintenance personnel to quickly perform maintenance work on the interior of the radio body 101. When the maintenance is completed, the top cover 104 is first covered on the top of the radio body 101, and the second rectangular rod 105 is inserted into the interior of the rectangular empty tube 102. Then, the positioning rod 301 is pulled upward to drive its end to be pulled out from the positioning hole 304. The compressed first spring 202 releases the elastic force to push the insertion rod 201 into the insertion hole 106 on the second rectangular rod 105, thereby completing the quick installation of the top cover 104. Then, the radio body 101 is placed on the upper surface of the mounting seat 100, and the rectangular empty tube 102 is sleeved on the outer side of the first rectangular rod 103. The positioning rod 301 is then pulled downward to automatically insert the insertion rod 201 into the insertion hole 106 on the first rectangular rod 103, thereby completing the quick installation of the radio body 101, reducing the inconvenience during the maintenance of the radio body 101 and improving the maintenance efficiency.
