When the latch bolt 210 is reversed, the driving device can be operated from the outside of the lock body 100, so that the limiting member 500 moves away from the blocking piece 400, and the limiting member 500 no longer interferes with the blocking piece 400, so that the latch bolt 210 can automatically slide to the outside of the lock body 100 under the action of the first elastic member 300, at this time, the latch bolt 210 is separated from the limitation of the bolt hole 120, then the latch bolt 210 can be rotated outside the lock body 100 to complete the reversal, and the latch bolt 210 and the limiting member 500 are reset after the reversal is completed, compared with the existing door lock with a reversing type latch bolt 210 inside, the latch bolt 210 can be rotated outside the lock body 100 more conveniently and easily; when the door lock is in use, the limiting piece 500 is in fit abutment with the blocking piece 400, so that the distance that the latch bolt 210 extends out of the lock body 100 can be limited, the latch bolt 210 is prevented from rotating due to the fact that the latch bolt is separated from the limit of the bolt hole 120, and the door lock can be used normally.

It can be understood that, referring to fig. 2 to 4, a second elastic member 600 is disposed in the mounting cavity 110, and the second elastic member 600 is used for resetting the limiting member 500. Specifically, one end of the second elastic member 600 is connected to the lock body 100, and the other end of the second elastic member 600 abuts against one side of the limiting member 500 away from the blocking plate 400, or the other end of the second elastic member 600 is connected to the limiting member 500, and after the limiting member 500 moves away from the blocking plate 400, the second elastic member 600 can generate an elastic force for driving the limiting member 500 to move close to the blocking plate 400. In the reversing process of the latch bolt 210, the limiting member 500 is moved away from the catch 400 by operating the driving device, then the latch bolt 210 automatically extends out of the lock body 100 under the action of the first elastic member 300 and is separated from the limitation of the bolt hole 120, so that the latch bolt 210 can be rotated outside the lock body 100 to complete the reversing, after the reversing is completed, the latch bolt 210 is pushed back into the lock body 100 to complete the resetting of the latch bolt 210, at this time, the elastic force of the second elastic member 600 can automatically move the limiting member 500 close to the catch 400 to complete the resetting of the limiting member 500, so that the limiting member 500 can be matched and abutted with the catch 400 again.

The second elastic member 600 may be disposed in various manners, for example, the second elastic member 600 may be disposed as a torsion spring or a compression spring.

It can be understood that, referring to fig. 2 to 4, the driving device includes a sliding slot 130 and a dial plate 510, the sliding slot 130 is disposed on an outer side wall of the lock body 100, the sliding slot 130 is disposed along a moving direction of the limiting member 500, the dial plate 510 is movably disposed through the sliding slot 130, and the dial plate 510 is connected to the limiting member 500. During the reversing process of the latch bolt 210, the driver plate 510 can be pushed along the sliding slot 130 outside the lock body 100, so that the position-limiting member 500 moves away from the blocking member 400. Specifically, as shown in fig. 2 and 3, the installation rod 220 moves in the left-right direction, the limiting member 500 moves in the up-down direction, and an included angle between the moving direction of the limiting member 500 and the moving direction of the installation rod 220 is 90 degrees, so that the first elastic member 300 can be prevented from pushing the limiting member 500 to move.

It can be understood that, in the specific implementation process, the driving device may also adopt other arrangement modes, for example, the driving device may include a knob and a transmission rod, the knob is rotatably disposed on the lock body 100, and at least a portion of the knob is located outside the lock body 100, the knob is provided with a threaded hole, the transmission rod may be disposed along the moving direction of the limiting member 500, one end of the transmission rod is connected to the limiting member 500, the other end of the transmission rod is inserted into the threaded hole, and the other end of the transmission rod is screwed to the inner wall of the threaded hole, so that the transmission rod can be moved by rotating the knob, and the limiting member 500 is further driven to move by the transmission rod, because the knob and the transmission rod can be self-locked, the moving direction of the limiting member 500 and the moving direction of the installation rod 220 may be the same or different.

Specifically, referring to fig. 4 and 5, the tongue hole 120 is located on the right side wall of the installation cavity 110, the installation rod 220 can move left and right, two sliding grooves 130 are provided, the two sliding grooves 130 are respectively disposed on the front and rear side walls of the installation cavity 110, two toggle pieces 510 are provided, the two toggle pieces 510 are connected to the front and rear side surfaces of the limiting member 500 in a one-to-one correspondence manner, the two toggle pieces 510 correspond to the two sliding grooves 130 in a one-to-one correspondence manner, and when in use, the limiting member 500 can move by simultaneously toggling the two toggle pieces 510.

It is conceivable that, referring to fig. 4 and 5, considering that the cooperation between the tumbler 510 and the sliding slot 130 may not effectively guide the movement of the tumbler 510, in some embodiments, the lock body 100 is provided with the first guide slot 140, the limiting member is provided with the first guide protrusion 520, the first guide protrusion 520 is slidably inserted into the guide slot 140, and the limiting member 500 can be ensured to accurately move by additionally providing the first guide protrusion 520 and the first guide slot 140. Of course, it is conceivable that the first guide groove 140 may be disposed on the limiting member 500 and the first guide protrusion 520 may be disposed on the lock body 100.

It is envisioned that a gap exists between the front or rear side of the retainer 500 and the corresponding inner wall of the mounting cavity 110. Due to the existence of the gap, when one of the toggle pieces 510 is toggled, the limiting piece 500 tilts forwards or backwards, and at the moment, the limiting piece 500 cannot move smoothly; when the two dialing pieces 510 are dialed simultaneously, the limiting piece 500 can move smoothly; therefore, the situation that one of the dialing pieces 510 is stressed to cause the limiting piece 500 to move away from the blocking piece 400 due to an unexpected factor can be reduced, and the situation that the latch bolt 210 accidentally and automatically extends out of the lock body 100 in the use process of the door lock is reduced or avoided.

In addition, the support plate 700 and the stop piece 400 can also be in fit abutment, so that the whole latch bolt 210 assembly can be prevented from being separated from the lock body 100.

It is conceivable that, referring to fig. 2 and 3, a side surface of the supporting piece 700 is disposed along a moving direction of the limiting member 500 and abuts against the limiting member 500, so that a side surface of the supporting piece 700 can also play a guiding role, and the limiting member 500 can move along a side surface of the supporting piece 700, thus ensuring smooth movement of the limiting member 500.

It is conceivable that, referring to fig. 2 to 4, a limiting block 150 is disposed in the mounting cavity 110, and the limiting block 150 can limit a distance that the latch bolt 210 retracts into the lock body 100, specifically, when the latch bolt 210 retracts into the lock body 100, and the latch bolt 210 is abutted against the limiting block 150 in a matching manner, the latch bolt 210 is not fully retracted into the lock body 100, that is, a part of the latch bolt 210 is still located in the bolt hole 120, so that it is avoided that the latch bolt 210 is completely retracted into the lock body 100, which causes difficulty or even incapability of extending the latch bolt 210 to the outside of the lock body 100 again, and it is ensured that the door lock can be normally used.

As can be imagined, referring to fig. 3 and 4, the lock body 100 includes a first casing 100a, a second casing 100b and a lining plate 100c, the first casing 100a is covered on the front end of the second casing 100b, the lining plate 100c is connected with the left end of the first casing 100a and the left end of the second casing 100b, the first casing 100a, the second casing 100b and the lining plate 100c enclose a mounting cavity 110, and a tongue hole 120 is disposed on the lining plate 100 c.
