A button waterproof device

Abstract

The invention discloses a waterproof device for a button. The waterproof device comprises a rain cover, a connecting steel plate, a PVC rainproof base, a PVC connecting pipe, a fixing screw, a PVC rainproof cover, connecting equipment holes, an emergency stop button, connecting screws, a threading hole, a PVC short pipe, a first PVC pipe plug, a second PVC pipe plug, a lightning arrester, an upright post pull rod, a moving contact, a fixed contact, a reset spring and an emergency stop button installation hole. Antiskid threads are arranged on the surface of the button, so that the probability of a safety accident caused by slipping of the button in an emergency can be effectively reduced; a short circuit of an electric appliance caused by splashing of rain or other water can be effectively avoided by the PVC rainproof base, the PVC connecting pipe, the PVC rainproof cover and a PVC special adhesive for connecting the PVC short pipe and the PVC pipe plugs in the waterproof device for the button; the phenomenon of a lightning stroke on the waterproof device for the button in cloudy and rainy weather can be prevented by the lightning arrester; and the waterproof device for the button is safe and economic and has very high practicability.
