The door lock body is internally provided with a bolt mechanism, a first latch mechanism and a latch mechanism. The bolt mechanism is provided with at least one first pusher, and the first latch mechanism is provided with a first bump and a first joint portion, the latch mechanism is provided with a latching portion and a card slot, and the latching portion forms an interference state with the first protrusion of the first latching mechanism; the first rotating shaft is used for an external preset handle Rotating in combination, each of which is provided with at least a sixth urging portion, a second arranging portion and an eighth urging portion, and the sixth urging portion forms an interference state with the first urging portion of the bolt mechanism; The first linkage mechanism has a rotatable mechanism, and is provided with a ninth pushing portion and a second joint portion. The ninth pushing portion is located between the two seventh pushing portions of the first rotating shaft and the seventh pushing portion. Forming an interference state, the second joint portion is combined with the first joint portion of the first latch mechanism to form an interlocking mechanism; the second linkage mechanism includes a rotating member and a push piece, and the rotating member is provided with a tenth shift Department and an eleventh moving part, the tenth moving part and the first The eighth pushing portion of the rotating shaft forms an interference state, and the pushing piece is provided with a twelfth pushing portion and a second protruding block, and the twelfth pushing portion and the eleventh moving portion form an interference state, and the second protruding block and the lock are The card slot of the latch mechanism forms an interference state.

The technical feature of the present invention is that the first rotating shaft is used to push the locking tongue mechanism inside the door locking body, the first latching mechanism and the latching mechanism to simultaneously generate an interlocking interlocking mechanism; thus, when the first latching mechanism is A latching column protrudes from the outside of the door lock body and is in a locked state, and when the first rotating shaft is rotated through the handle, the seventh pushing portion pushes the ninth pushing portion, and then the second joint portion pushes the first joint portion to the door lock The inside of the seat moves so that the first latch post can move toward the inside of the door lock body, and at the same time, the eighth shifting portion pushes the tenth pushing portion, and the eleventh pushing portion pushes the twelfth pushing portion, so that the pushing piece can be pushed toward Displacement, and then the second bump pushes the card slot upward to disengage the latch portion from the first bump, so that the first latch post moves toward the inside of the door lock body to be unlocked, thereby providing the user It is only necessary to open the door step (that is, by turning the handle), the first latch mechanism of the door lock body can be unlocked quickly and easily, and the conventional multi-segment door lock must be rotated multiple times to unlock the knob. Segmental door lock Lock status.

The twelfth pushing portion 421 allows the pushing piece 42 to move upward; when the pushing piece 42 is displaced upward, the second protrusion 422 of the pushing piece 42 can push the locking groove 142 of the latch mechanism 14 upward (ie, lock The latch mechanism 14 is displaced upwardly. At this time, the latching portion 141 of the latch mechanism 14 can be disengaged from the first protrusion 122 of the first latch mechanism 12, so that the first latch post 121 of the first latch mechanism 12 can be oriented. The door lock body 1 is moved (retracted) to be unlocked.

Moreover, when the pushing piece 42 is displaced upward, the third protrusion 423 of the pushing piece 42 can push the fifth pushing part 136 of the first linking rod 135, and the first linking rod 135 is used to rotate the second rotating shaft 133. Finally, the third pushing portion 132 of the second latching mechanism 13 is pushed by the fourth pushing portion 134 of the second rotating shaft 133, so that the second latching post 131 of the second latching mechanism 13 can move toward the inside of the door lock body 1 In) and unlocked.

Therefore, the technical feature of the present invention is that the first rotating shaft 2 is used to push the tongue mechanism 11 inside the door lock body 1, the first latch mechanism 12, the second latch mechanism 13 and the latch mechanism 14 simultaneously. The interlocking mechanism for unlocking; thus, the user can quickly and easily perform the first latch mechanism 12 and the second latch mechanism 13 of the door lock body 1 by simply opening the door step (ie, by rotating the handle). Unlock, to avoid the conventional multi-segment door lock must be rotated multiple times to unlock the knob, in order to make the traditional multi-stage door lock unlocked.
