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

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The trigger device of the isolating switch of the utility model comprises an isolating baffle 3, the isolating baffle 3 is provided with a rotating shaft 1 and a positioning pin 5 for limiting, a torsion spring 2 is wound around the rotating shaft 1; the isolating baffle 3 is provided with a cam-shaped structure for triggering a switch 4, and the switch 4 is located on a bottom plate 6. Among them, the isolating baffle 3 contacts the lock core of the external isolating lock. The bottom plate 6 is provided with a waist-shaped hole. The positioning pin 5 is located in the waist-shaped hole of the bottom plate 6 to achieve the limiting of the isolation state and the non-isolation state. The bottom plate 6 is provided with a plurality of mounting holes.

[0022] When in use, the lock core is rotated by a specific key, and the lock core extends to push the isolation baffle 3. The isolation baffle 3 rotates, and the switch 4 is triggered by the specific cam shape on the isolation baffle 3. The positioning pin 5 installed on the isolation baffle 3 realizes the limit of the isolation state and the non-isolation state in the waist-shaped hole of the bottom plate 6. After the lock core is retracted, the isolation baffle 3 is reset under the action of the torsion spring 2.
