Vibration isolator displacement signal indication device

The invention discloses a vibration isolator displacement signal indication device, which comprises a cover plate, an outer sleeve inner stop ring, a lock plate and an insulated spring sheet. The device also comprises a contact disc (8) arranged on the outer sleeve inner stop ring, a contact point (7) arranged on the insulated spring sheet, a light-emitting diode (4) arranged on the cover plate, and a power supply (6) arranged on the contact disc. The two ends of the insulated spring sheet are contacted with the contact disc and the lock plate respectively; one end of the power supply is connected with the contact point, and the other end of the power supply is connected with one end of the light-emitting diode; and the other end of the light-emitting diode is connected with the contact disc. When the vibration isolator is damaged internally, the lock plate moves downwards, the contact point makes contact with the contact disc, and the light-emitting diode is powered on and emits light, and sends a signal, an
