Abstract

The utility model relates to a water-proof device for a Christmas lamp base, which is a concave ring part formed at the outside of the open end of a lamp base. Two ends of the concave ring part are respectively formed into an end flange and a side flange. The utility model is also provided with the water-proof sleeve of a ring cylinder which is made from rubber. A cross section is formed into an outer ring wall which is arranged at the lower end of the lamp base. The upper end of the external ring wall is connected with an inclined lower end part which is formed from the lower end of an arc end piece body, and the inner side is inwards extended with an inner flange. The lower side of the inner flange is extended with a short inner ring wall. The inner ring wall and the outer ring wall constitute an inner concave edge. The inner concave edge of the water-proof sleeve is sheathed in the flange of the end of the lamp base. A lower end part pushes the edge flange of the lamp base. When a lamp is screwed in the lamp base, the end piece body of the water-proof sleeve is upwards and elastically attached to the surface of a lamp bulb and a flange in the water-proof sleeve is downwards pushed and attached to the surface of the lamp bulb, which reaches the water-proof effect.
