[0022] The above and other technical features and advantages of the utility model will be described in more detail below with reference to the drawings.

[0023] Embodiment one

[0024] As Figure 1 , Figure 2and Figure 3 as shown, Figure 1 It is the structure front view of the mechanical car coupler trigger device of the motor train unit; Figure 2 It is the structure plan view of the impact rod; Figure 3 It is the structure view of the impact block.

[0026] By the one end of impact rod 1 corresponding top in car coupler trigger, impact block 2 is first away from impact disc 3, and the impact of impact block 2 is made to impact block 2 hit impact disc 3, so that the end of impact rod 1 can realize the impact of car coupler trigger, thereby realizing the activation of car coupler trigger, and spacing disc 4 is used for limiting the moving distance of impact block 2 to the direction away from impact disc 3.

[0027] Preferably, the weight of the impact block 2 is not less than 2 kg, so as to ensure that the impact force is sufficient to activate the car coupler trigger.

[0028] Generally, the impact rod 1 is provided as a stainless steel hollow rod to ensure the lightweight of the motor train unit mechanical car coupler trigger device.

[0029] The impact disc 3 and the spacing disc 4 separate the impact rod 1 into a hand-held section, an impact section and an abutting section arranged in sequence, the impact section is between the impact disc 3 and the spacing disc 4, the impact section and the abutting section are on both sides of the impact disc 3, the abutting section is provided with a clamping frame 5 at the end away from the impact disc 3, the clamping frame 5 is used for clamping and fixing with the car coupler trigger to ensure the directional conduction of the impact force of the impact rod 1.

[0030] Generally, the hand-held section is provided as 150 mm, which is used for the operator to hold and fix the position of the impact rod 1, and at the same time, a safe operation distance is reserved.

[0031] The side close to the impact block 2 of the spacing disc 4 is provided with a buffer pad layer 6, the buffer pad layer 6 is made of rubber material, and the impact of the impact block 2 on the spacing disc 4 is reduced.

[0032] Preferably, the side away from the impact block 2 of the spacing disc 4 is provided with a hand guard plate 7, the hand guard plate 7 is provided as a disc, and the hand guard plate 7 is fixedly sleeved on the impact rod 1, which is used for protecting the operator holding the hand-held section and ensuring the safety of operation.

[0034] The impact force when activating the coupler trigger is approximately 80N. Through multiple simulated impact tests, this invention uses a 2Kg impact block 2 impacting the impact plate 3 at a speed of 10m / s to generate a transient impact force.
