Example 1

Referring to fig. 1 to 7, the latch bolt reversing structure of the present invention is schematically shown, including a latch bolt 30, a connecting rod 40, a guide 20, and a lock body 10. The lock body 10 is provided with a mounting hole 11, and the latch 30 can be retracted into the mounting hole 11 or extended out of the mounting hole 11.

The connecting rod 40 is cylindrical, one end of the connecting rod 40 is connected to the latch bolt 30, the other end of the connecting rod 40 is slidably connected to the guide 20, and the latch bolt 30 can move toward or away from the guide 20 along the axial direction of the connecting rod 40 through the connection and guidance of the connecting rod 40. Meanwhile, the connecting rod 40 is rotatably connected to the guide device 20 around the axis thereof, the latch bolt 30 is rotated by applying force, and the latch bolt 30 drives the connecting rod 40 to rotate relative to the guide device 20, so that the direction change of the latch bolt 30 can be realized, and the door can be adapted to the inward opening door or the outward opening door in different consumer homes.

The lock body 10 is provided with a groove 14 arranged in parallel with the connecting rod 40, the guide device 20 is provided with a slide block 23, the slide block 23 is slidably connected with the groove 14, so that the guide device 20 can slide relative to the lock body 10 along the groove 14, when the guide device 20 can freely slide relative to the lock body 10, force is applied to draw the oblique tongue 30 out of the lock body 10 along the axial direction of the connecting rod 40, the oblique tongue 30 completely extends out of the mounting hole 11 of the lock body 10, and a lock assembling person can change the direction of the oblique tongue 30. The structure can be used without disassembling the lock body 10, when a locking person applies force to draw the oblique tongue 30 out of the mounting hole 11 of the lock body 10, the guide device 20 can slide relative to the lock body 10 through the sliding block 23 and the groove 14, after the oblique tongue 30 is completely drawn out of the mounting hole 11, the locking person applies force to rotate the oblique tongue 30 to change the direction, then the oblique tongue 30 is pushed into the mounting hole 11, the change of the oblique tongue 30 can be completed, and the change of the oblique tongue 30 is very convenient.

In order to prevent the latch bolt 30 from being accidentally separated from the mounting hole 11 when the consumer normally uses the door lock, a locking mechanism for preventing the guide device 20 and the lock body 10 from sliding relatively is arranged between the guide device 20 and the lock body 10, when a lock installer reverses the latch bolt 30, the locking mechanism is unlocked to allow the guide device 20 and the lock body 10 to slide relatively, and when the lock installer finishes reversing the latch bolt 30, the locking mechanism is locked to prevent the guide device 20 and the lock body 10 from sliding relatively.

Referring to fig. 3, 4 and 7, the locking mechanism includes a locking member 50, and a sliding slot 12 and a limiting hole 13 which are disposed on the lock body 10, the sliding slot 12 is a linear slot, the limiting hole 13 is located at one end of the sliding slot 12, and the sliding slot 12 penetrates through an inner side wall of the limiting hole 13, wherein a diameter of the limiting hole 13 is greater than a width of the sliding slot 12. The locking part 50 comprises a connecting piece 51 and a locking piece 52 which are connected, one end of the connecting piece 51 is connected to the locking piece 52, the other end of the connecting piece 51 penetrates through the limiting hole 13 and is movably connected to the guide device 20, the connecting piece 51 moves relative to the guide device 20 to enable the locking piece 52 to move close to or far away from the guide device 20, the locking piece 52 is embedded in the limiting hole 13, at the moment, the locking piece 52 cannot directly move from the limiting hole 13 into the sliding groove 12 to lock the guide device 20 and the lock body 10, when an external force presses the oblique tongue 30, the oblique tongue 30 is close to the guide device 20 under the connection and guiding of the connecting rod 40, namely, the oblique tongue 30 is contracted into the mounting hole 11; when the oblique tongue 30 needs to be drawn out of the mounting hole 11 for reversing, the connecting member 51 is driven to move relative to the guide device 20 by applying force to force the locking member 52 to exit from the limiting hole 13, the connecting member 51 can directly move into the sliding groove 12 from the limiting hole 13 and move in the sliding groove 12, the guide device 20 can slide relative to the lock body 10, and the oblique tongue 30 is drawn out of the mounting hole 11 by applying force to reverse.

Further, the locking member 50 may be preferably a screw, wherein the connecting member 51 is a threaded section of the screw, and the locking member 52 is a head of the screw. Correspondingly, the limiting hole 13 is a circular hole, and the shape of the locking piece 52 is matched with the shape of the limiting hole 13. The guide device 20 includes a first guide 21 and a second guide 22 which are perpendicular to each other and connected to each other, the first guide 21 and the second guide 22 are both plate-shaped, a connecting member 51 is movably connected to the first guide 21, and a connecting rod 40 is slidably connected to the second guide 22.
