A door locker latch receptacle buried in a floor is provided to fix the latch receptacle at a latch groove of the floor without using silicon or wood pieces and prevent surrounding contamination by preventing a dust guard member from being separated through an upper opening of the latch receptacle body. A door locker latch receptacle buried in a floor comprises a latch receptacle body(10), a wedge member(20), a dust guard member(30), a separation preventing unit, and an elastic member(40). The latch receptacle body is shaped like a cylinder having a latch groove(11), is divided by a plurality of radial slits(12), and has a plurality of wedge working pieces(13) which are formed as taper wedge surfaces(14). The wedge member is formed with wedge working surfaces(21) corresponding to the tapered wedge surfaces. The dust guard member, which is inserted in the latch receptacle body, opens and closes an upper opening of the latch receptacle body. The separation preventing unit prevents the dust guard member from being separated through the upper opening. The latch receptacle body includes an upper body(10A) having a male thread(19a), and a lower body(10B) having a female thread(19b) corresponding to the male thread. An inclined surface(15) is formed at a lower end of the wedge piece. The separation preventing unit has a catching protrusion and a catching pin.
