The invention discloses a subway third-rail insulating bracket. The subway third-rail insulating bracket comprises an insulating fastener (1), an insulating carrier frame (2) and a base (3), wherein the insulating bracket (2) comprises a top beam (2.1), a lower supporting plate (2.2) and an inclined arm (2.3); the rear end of the top beam (2.1) and the rear end of the lower supporting plate (2.2) are fixed on the front end surface of the inclined arm (2.3); the insulating fastener (1) is composed of a vertical plate (1.1) and an inclined supporting plate (1.2); the upper end surface of the vertical plate (1.1) is a lower inclined surface (1.3); the front end of the bottom surface of the top beam (2.1) is an upper inclined surface (2.4); the insulating fastener (1) is in threaded connection with the top beam (2.1) through a bolt (4) perpendicular to the upper inclined surface (2.4); and the lower supporting plate (2.2), the inclined arm (2.3), the top beam (2.1) and the insulating fastener (1) form a chamber for accommodating the upper part of a third rail (5). The bracket is good in stability and firmness, and can avoid potential safety hazards.
