Technical Field

[0001] The utility model relates to the field of rail transit trains, and particularly to a novel disconnector device. Background Art

[0002] The traditional disconnector used for rail transit vehicle doors is composed of a switch box, a cam, a torsion spring, a mounting plate, a switch box cover, a micro switch, etc. The existing isolation lock switch assembly occupies a large installation space of the vertical cover plate in the vehicle length direction and has a high cost. For the reed type isolation lock switch, the lock tongue is prone to accidentally trigger the switch, and the reliability is low.

[0003] Therefore, it is necessary to specifically develop a novel disconnector device to overcome the above problems. Summary of the Utility Model

[0004] Purpose of the utility model: Aiming at the deficiencies and defects of the prior art, the utility model provides a novel disconnector device, which has the beneficial effects of small occupied space in the vehicle width direction, small requirement for the space of the side vertical mounting cover plate of the vehicle body, low cost and high reliability.

[0006] Wherein, a slot hole is formed on the mounting plate.

[0007] Wherein, the retaining pin is matched with the slot hole for limiting.

[0008] Wherein, the trigger block corresponds to the lock tongue of the external isolation lock.

[0009] Wherein, the mounting plate is mounted on a rail transit train.

[0010] Wherein, the mounting plate is mounted on the vehicle door of a rail transit train.

[0011] Beneficial effects: Compared with the prior art, the utility model has the following remarkable advantages: The novel disconnector device of the utility model occupies a small space in the vehicle width direction and has a small requirement for the space of the side vertical mounting cover plate of the vehicle body; it adopts a novel triggering method, the trigger block drives the rotating rod to rotate under the constraint of the retaining pin, and the mechanical cooperation between the retaining pin and the slot hole on the mounting plate plays a limiting role; the self-resetting function can be realized through the torsion spring. It has the beneficial effects of small occupied space in the vehicle width direction, small requirement for the space of the side vertical mounting cover plate of the vehicle body, low cost and high reliability.

[0019] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] The novel disconnector device of the present utility model includes a switch 1 and a mounting plate 2. The mounting plate 2 is provided with a trigger block 4, a rotating rod 5 and a stop pin 6 connected in sequence. The rotating rod 5 is connected to a torsion spring 3 for resetting. Among them, the mounting plate 2 is provided with a slot hole. The stop pin 6 cooperates with the slot hole for limiting. The trigger block 4 corresponds to the locking tongue 7 of the external isolation lock 8. The mounting plate 2 is installed on a rail transit train. The mounting plate 2 is installed on the vehicle door of a rail transit train.

[0021] During use, by rotating the lock core of the external isolation lock 8 with a key, the locking tongue 7 of the isolation lock extends out. The locking tongue 7 pushes the trigger block 4. The trigger block 4 is connected to the rotating rod 5. The rotating rod 5 rotates counterclockwise under the constraint of the stop pin 6, thereby triggering the switch 1, and the disconnector device sends a signal to unlock; at the same time, the disconnector device can be self-reset through the torsion spring 3; at the same time, through the mechanical cooperation between the stop pin 6 and the slot hole at the corresponding position of the mounting plate 2, a limiting effect can be achieved.

[0022] The novel disconnector device of the present utility model occupies little space in the vehicle width direction and has little requirement for the space of the side standing cover plate of the vehicle body; it adopts a novel triggering method, and the trigger block drives the rotating rod to rotate under the constraint of the stop pin, and the stop pin and the slot hole of the mounting plate are mechanically matched to play a limiting role; the self-reset function can be realized through the torsion spring. It has the beneficial effects of occupying little space in the vehicle width direction, having little requirement for the space of the side standing cover plate of the vehicle body, low cost and high reliability.
