Description

Technical Field

[0001] The utility model relates to the field of rail transit trains, in particular to a trigger device for an isolating switch. Background Art

[0002] The traditional isolating switch used in rail transit vehicle doors is composed of a switch box, a cam, a torsion spring, a mounting plate, a switch box cover and a micro switch. The principle is: the swivel arm is rotated by a square key, and the rotation of the swivel arm drives the lock tongue to extend, thereby triggering the isolating lock switch assembly. The original isolating lock switch assembly occupies a large installation space on the vertical cover plate in the direction of the vehicle length and has a high cost. The reed-type isolating lock switch is easy to trigger the switch by mistake, and the reliability is low.

[0003] Therefore, it is necessary to develop a new type of trigger device for the isolating switch to overcome the above problems. Utility Model Content

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The trigger device of the isolating switch of the utility model comprises an isolating baffle 4, which is connected to a rotating shaft 1, a torsion spring 2 is sleeved on the rotating shaft 1, and a limiting pin 3 and a pin 2 5 are arranged on both sides of the rotating shaft 1; the isolating baffle 4 is provided with a cam-shaped structure for triggering a switch 6, and the switch 6 is located on a bottom plate 7. Among them, the isolating baffle 4 contacts the lock core of the external isolating lock. The rotating shaft 1 is located between the pin 1 3 and the pin 2 5, and the limiting of the isolation state and the non-isolation state is achieved by the pin. The pin 1 3 and the pin 2 5 are located on the bottom plate 7. The bottom plate 7 is provided with a plurality of mounting holes.

[0021] When in use, the lock core is rotated by a specific key, and the lock core extends to push the isolation baffle 4. The isolation baffle 4 rotates, and the switch 6 is triggered by the specific cam shape on the isolation baffle 4. The isolation baffle 4 moves between the pins to achieve the limit of the isolation state and the non-isolation state by the pins. After the lock core is retracted, the isolation baffle 4 is reset under the action of the torsion spring 2.
