[0037] Compared with the prior art, the multistage interlocking operator provided by the utility model has the following advantages:

[0038] The multi-stage interlocking operator provided by the utility model, through the connecting rod 12 included by the first locking assembly, and one end of the connecting rod 12 is connected with the unlocking mechanism, so that when the unlocking mechanism rotates, the connecting rod 12 can be driven to move. The reversing mechanism in the application is located at the other end of the connecting rod 12, and the reversing mechanism is formed with a jack at the position corresponding to the connecting rod 12, so that when the connecting rod 12 moves with the unlocking mechanism, the end of the connecting rod 12 away from the unlocking mechanism can move towards or away from the reversing mechanism, and then the jack is inserted or pulled out, so that the unlocking of the reversing mechanism is realized.

[0039] That is, when the unlocking mechanism is in the locked state, the end of the connecting rod 12 away from the unlocking mechanism is inserted into the jack, so that the locking of the reversing mechanism is realized. When the unlocking mechanism is unlocked and rotates, the connecting rod 12 can be driven to move, so that the end of the connecting rod 12 away from the unlocking mechanism is pulled out of the jack, the unlocking of the reversing mechanism is realized, and then the reversing mechanism can rotate to adjust the direction.

[0040] Further, the second locking assembly in the application includes the first rotating disc 3 arranged on the first rotating shaft 11 and the second rotating disc 4 arranged on the second rotating shaft 17, the first rotating disc 3 is formed with the first groove 301 and the second groove 302, the position between the first groove 301 and the second groove 302 is formed with the clamping part 303, and the second rotating disc 4 is formed with the third groove 401. Therefore, when the reversing mechanism is locked, the third groove 401 is aligned with the clamping part 303, so that the third rotating disc 5 cannot rotate, and then the second rotating shaft 17 cannot rotate, so that the locking of the traction mechanism is realized.

[0041] When the unlocking mechanism unlocks the reversing mechanism, and the reversing mechanism drives the first rotating disc 3 to rotate to the first groove 301 or the second groove 302, the second rotating disc 4 can be unlocked, so that the second rotating shaft 17 can rotate, and then the unlocking of the traction mechanism is realized.

[0042] When the traction mechanism rotates and drives the second rotating shaft 17 to rotate, the second rotating disc 4 rotates relative to the first rotating disc 3, the third groove 401 is misaligned with the first groove 301 or the second groove 302, so that the first rotating disc 3 cannot rotate, that is, when the traction mechanism is controlled, the reversing mechanism cannot move, so that the reversing of the train during speed change is avoided, the smoothness of the train is affected, and the safety problem is avoided.

[0043] Only when the traction mechanism returns to the initial position, i.e., the third groove 401 is aligned with the first groove 301 or the second groove 302, can the reversing action be performed, but when reversing, such as switching from the first groove 301 to the second groove 302, the clamping portion 303 needs to be passed through, so before reaching the second groove 302, the third groove 401 is always aligned with the clamping portion 303, thereby ensuring that when reversing, the gear shifting operation cannot be performed, achieving interlocking between the unlocking mechanism, the reversing mechanism, and the traction mechanism.

[0044] Optionally, as shown in Figure 1 Combined with Figure 2 The unlocking mechanism in the application includes an unlocking assembly and a third turntable 5; the unlocking assembly is connected with the third turntable 5 and can drive the third turntable 5 to rotate, the third turntable 5 is formed with a connecting column 504, the connecting column 504 is connected with a rotating shaft piece 505, the rotating shaft piece 505 is rotationally connected with the connecting column 504, and one end of the connecting rod 12 is connected with the rotating shaft piece 505.

[0045] Since the connecting rod 12 needs to be movable relative to the insertion hole, and the unlocking process of the unlocking assembly needs to be rotated, by forming the connecting column 504 on the third turntable 5 and the rotating shaft piece 505 rotationally connected with the connecting column 504, on the one hand, the connecting column 504 can be driven to move when the third turntable 5 rotates, thereby realizing the synchronous movement of the connecting rod 12 following the connecting column 504, and on the other hand, the connecting rod 12 can rotate relative to the connecting column 504 during the movement, thereby avoiding the problem that the connecting rod 12 cannot be smoothly unlocked due to jamming during the pulling process, and setting the problem of the connecting rod 12 being damaged.

[0046] Optionally, as shown in Figure 1 Combined with Figure 2 The unlocking assembly in the application includes a lock cylinder 2 and a lock shell; the lock cylinder 2 is connected with the third turntable 5, the lock shell covers the outside of the lock cylinder 2, and the lock cylinder 2 can rotate relative to the lock shell.

[0047] The lock shell in the application covers the outside of the lock cylinder 2, the lock cylinder 2 can rotate relative to the lock shell, the lock shell can provide a stable mounting space for the lock cylinder 2, and by connecting the lock cylinder 2 with the third turntable 5, when the lock cylinder 2 rotates, the third turntable 5 can be driven to rotate, thereby realizing the driving of the connecting rod 12 and the unlocking of the reversing mechanism.

[0048] Optionally, as shown in Figure 2 The third turntable 5 in the application is formed with a limiting gap 501, and the lock shell is formed with a limiting column 6 at a position corresponding to the limiting gap 501 to limit the rotation angle of the third turntable 5.

[0049] Since the lock shell is fixed, by connecting the limiting column 6 with the lock shell, the limiting of the third turntable 5 can be ensured.

[0050] Correspondingly, the application can limit the rotation angle of the third rotating disc 5 by forming a limiting notch 501 on the third rotating disc 5, which cooperates with the limiting column 6. Preferably, the limiting notch 501 in the application can make the third rotating disc 5 rotate by 45°, that is, the included angle between the two contact end faces of the limiting notch 501 is 45°, thereby realizing the limitation of the rotation angle of the third rotating disc 5.

[0051] Optionally, as Figure 1 Combining Figure 2 shown, the third rotating disc 5 in the application is formed with a first recess 502 and a second positioning recess 503, and the lock shell is formed with a positioning assembly at a position corresponding to the first recess 502. The positioning assembly can be embedded in the first recess 502 or the second positioning recess 503.

[0052] Through the first recess 502 and the second positioning recess 503 formed on the third rotating disc 5 and the further connected positioning assembly on the lock shell, the third rotating disc 5 can be kept in the unlocked and locked states by the cooperation of the positioning assembly and the first recess 502 or the second positioning recess 503, that is, when the positioning assembly is located in the first recess 502, the unlocking mechanism is in the locked state. If the lock cylinder 2 does not produce rotation, the positioning assembly is always located in the first recess 502, so that the lock cylinder 2 will not be activated due to vibration and the like.

[0053] Correspondingly, when the lock cylinder 2 rotates and the positioning assembly enters the second recess, under the action of the second recess, the lock cylinder 2 can also be kept in the unlocked state without the operation of the driver, thereby improving the reliability of the unlocking mechanism.

[0054] Preferably, as Figure 1 Combining Figure 2 shown, the positioning assembly in the application includes a positioning column 7 and a rotating wheel 8. The positioning column 7 is connected with the lock shell, and the rotating wheel 8 is arranged on the positioning column 7 and can rotate relative to the positioning column 7.

[0055] The positioning column 7 can be fixedly connected with the lock shell and provide a mounting position for the rotating wheel 8. Correspondingly, since the third rotating disc 5 needs to be able to rotate relative to the positioning assembly, the sliding friction between the third rotating disc 5 and the positioning assembly can be converted into rolling friction by the rotating wheel 8 arranged on the positioning column 7, so that the rotation process is smoother, and the wear degree of the third rotating disc 5 can be reduced to a certain extent, thereby improving the service life of the overall device.

[0056] Optionally, as Figure 1 Combining Figure 2 shown, the unlocking assembly in the application further includes an unlocking piece 1. The lock cylinder 2 is formed with an unlocking hole and a slot communicating with the unlocking hole. The unlocking piece 1 is formed with an insertion part and a matching part. The insertion part corresponds to being inserted into the unlocking hole, and the matching part corresponds to being inserted into the slot.

[0057] The plug-in part of the unlocking piece 1 in the application is in a column structure, preferably, two insertion slots are provided in the application, and the axes of the two insertion slots are collinear. Correspondingly, the matching parts formed on the plug-in part are oppositely arranged, so as to correspond to the insertion slots. When the plug-in part is inserted into the unlocking hole, the matching parts can be accurately inserted into the insertion slots, and then the unlocking piece 1 can drive the lock cylinder 2 to rotate, so as to realize the unlocking of the unlocking mechanism.

[0058] Optionally, as shown in Figure 1 Combined with Figure 2 It is shown that the reversing mechanism in the application further includes a reversing handle 9 and a shell 10. The reversing handle 9 is connected with the first rotating shaft 11 and drives the first rotating shaft 11 to rotate. The shell 10 covers the reversing handle 9, and the reversing handle 9 can rotate relative to the shell 10.

[0059] The shell 10 in the application can provide a mounting basis for the reversing handle 9 and the first rotating shaft 11. Correspondingly, the reversing handle 9 in the application is in rotational connection with the shell 10, so that when it is necessary to adjust the direction, the reversing handle 9 can be controlled to realize the adjustment.

[0060] Optionally, as shown in Figure 1 Combined with Figure 2 It is shown that the first locking assembly in the application further includes a spring 13, a limiting ring 1201 and a guide block 14. The guide block 14 is connected with the shell 10 and is formed with a guide hole. The spring 13 is sleeved on the connecting rod 12. The limiting ring 1201 is arranged on the connecting rod 12, and the outer diameter of the limiting ring 1201 is greater than the outer diameter of the spring 13, so as to limit one end of the spring 13. The connecting rod 12 penetrates through the guide hole and can be plugged into the insertion hole. The other end of the spring 13 is located in the guide hole and is fixedly connected with the guide block 14.

[0061] The spring 13 is sleeved on the connecting rod 12, and in order to ensure the stable connection of the spring 13, the limiting ring 1201 is further arranged on the connecting rod 12 in the application, so as to stably limit one end of the spring 13. The other end of the spring 13 is arranged in the guide hole, so that both ends of the spring 13 are positioned.

[0062] Correspondingly, by arranging the guide hole, support and guidance can be provided for the end of the connecting rod 12 away from the unlocking mechanism, so that the unlocking and locking processes are more stable, and the problem that the connecting rod 12 cannot be smoothly inserted into the insertion hole due to the influence of gravity caused by the excessive length of the connecting rod 12 is avoided.

[0063] The spring 13 sleeved on the connecting rod 12 can be stretched when the lock cylinder 2 is unlocked, and when the driver operates the unlocking piece 1 from unlocking to locking, the smooth return of the lock cylinder 2 to the locked state can be ensured, and the stability and reliability of the locked state can be ensured.

[0064] Optionally, as shown inFigure 1 In combination Figure 2 As shown in the drawings, the traction mechanism in the application further comprises an adjusting handle 15 and an adjusting disc 16, the adjusting handle 15 is connected with the adjusting disc 16, and one end of a second rotating shaft 17 is connected with the adjusting disc 16.
