[0022] The utility model provides Figures 1 to 3 The device for freely adjusting the angle of a locomotive end coupling shown includes a coupling body 1 , one end of which is rotatably connected to an angle adjustment mechanism 3 , which can be used for adjusting the angle of one end of the coupling body 1 .

[0023] Specifically, the angle adjustment mechanism 3 includes a rotating sleeve 4, and a protruding end 5 is fixed to the end of the rotating sleeve 4 away from the coupling body 1. The other end of the coupling body 1 is connected to the flexible pipe 2, and the protruding end 5 is connected to the air supply component of the locomotive. One end of the flexible pipe 2 can be connected to other equipment on the locomotive to supply air to other equipment. The air supply component generates wind power, and the wind power passes through the protruding end 5, the rotating sleeve 4, the coupling body 1 and the flexible pipe 2 in sequence, and finally reaches other equipment on the locomotive.

[0024] One end of the interior of the rotating sleeve 4 is communicated with the interior of the coupling body 1 , and the other end of the interior of the rotating sleeve 4 is communicated with the interior of the protruding end 5 .

[0025] A first annular slider 8 and a second annular slider 9 are fixed to the inner wall of the rotating sleeve 4, with a gap between the first annular slider 8 and the second annular slider 9. Two annular grooves 10 are provided on the outside of the connecting pipe body 1 for rotating the first annular slider 8 and the second annular slider 9, respectively, and an external thread 6 is provided on the outside of the protruding end 5.

[0026] In the actual operation of the present invention, the protruding end 5 is fixedly connected to the air supply assembly of the locomotive through the external thread 6. When the angle of the coupling body 1 needs to be changed, the angle between the coupling body 1 and the rotating sleeve 4 is changed by rotating the rotating sleeve 4, thereby adapting to the installation requirements of different angles of the coupling body 1.

[0027] The first annular slider 8 and the second annular slider 9 protruding from the inside of the rotating sleeve 4 serve to connect the rotating sleeve 4 and the coupling body 1, thereby preventing the rotating sleeve 4 and the coupling body 1 from separating when they rotate relative to each other. When wind passes through, the first annular slider 8 and the second annular slider 9 and the corresponding annular slide groove 10 cooperate to make the coupling body 1 and the protruding end 5 parallel to each other, thereby reducing the loss of wind force.

[0028] A conical cylinder 11 is fixed on the inner wall of the protruding end 5. The two ends of the conical cylinder 11 are connected to each other, and the radius of the end of the conical cylinder 11 close to the rotating sleeve 4 is smaller than the radius of the end away from the rotating sleeve 4. When the wind passes through the conical cylinder 11, the path of the wind becomes smaller, so that the air pressure becomes larger, causing the first annular slider 8 and the second annular slider 9 to contact the corresponding annular slide groove 10, which plays a stabilizing role.

[0029] A connecting hole is provided on the outside of the rotating sleeve 4, and a fixing screw 7 is fitted into the inner thread of the connecting hole. One end of the fixing screw 7 extends into the rotating sleeve 4, and the inserted end of the fixing screw 7 is pressed tightly against the outside of the connecting pipe body 1. The inserted end of the fixing screw 7 is arranged between the first annular slider 8 and the second annular slider 9.

[0030] By tightening the fixing screw 7 , the angles of the rotating sleeve 4 and the coupling body 1 can be fixed.

[0031] Sealing gaskets are fixed inside the two annular chutes 10 .
