Low-melting-point alloy sliding block and sliding rail combination for temperature control window closer

The utility model discloses a low-melting-point alloy sliding block and sliding rail combination for a temperature control window closer, the sliding rail comprises an outer groove body and an inner groove body, the inner groove body is fixedly connected in the outer groove body through a rivet in a Stokes riveting mode, the sliding block comprises a positioning structure made of low-melting-point alloy materials, under normal conditions, a fireproof window sash is opened, and the sliding rail is fixed to the outer groove body. A connecting rod of the window closer is limited, clamped and supported between the fireproof window sash and the window frame through a positioning structure, so that the window sash is kept in a normally open state; when a fire disaster occurs, the positioning structure is continuously burnt by flames, the temperature controller of the positioning structure is melted and loosened when the temperature rises to the melting point of the low-melting-point alloy material, the sliding end
