When the door is closed, the two-way tongue is pressed to retract into the housing 11. After the extrusion force disappears, the two-way bolt can extend into the bolt hole in the door frame. It should be noted that, when the bidirectional bolt is inserted into the bolt hole, the bidirectional bolt is also retracted into the housing 11 by an external force, and at the same time, the position of the lock body 10 is shifted, so that the situation that the main bolt 123 cannot be matched with the bolt hole occurs, and even if the driving motor 142 rotates, the main bolt 123 is not driven to extend, so that the driving motor 142 is locked, and the power consumption of the driving motor 142 is too high, therefore, the inventor proposes to perform the anti-insertion treatment on the latch bolt assembly 19 after the latch bolt 191 is inserted into the bolt hole, so as to reduce the power consumption of the driving motor 142 and achieve energy saving.

The triangular tongue 231 is connected to the triangular tongue connecting member 233, the triangular tongue connecting member 233 is movably disposed on the bottom housing 112 to drive the triangular tongue 231 to extend out of the housing 11 or retract from the housing 11, and the triangular tongue elastic member 235 is disposed around the triangular tongue connecting member 233 to provide a force for the triangular tongue 231 to extend out of the housing 11.

The triangular tongue 231 has a substantially triangular plate-like structure, and when the triangular tongue 231 is pressed in the direction opposite to the direction X, for example, by the door frame, the triangular tongue 231 retracts from the housing 11, and when the force disappears, the triangular tongue 231 is forced out of the housing 11 by the triangular tongue elastic member 235. It should be noted that, the door frame is not provided with a latch hole corresponding to the triangular latch 231, so that when the door is closed, the triangular latch 231 retracts into the housing 11 and drives the triangular latch connecting member 233 to move.

The third unlocking member 24 is provided in the moving path of the triangular tongue connecting member 233. When the triangular tongue connecting piece 233 extends out, the third unlocking piece 24 is driven to rotate clockwise, the rotation of the third unlocking piece 24 drives the second connecting part 2134 to move in the direction opposite to the direction Y, so that the anti-insertion connecting piece 213 drives the anti-insertion rotating piece 211 to separate from the inclined tongue connecting piece 193, the effect of extending out and removing the anti-insertion of the triangular tongue 231 is realized, the triangular tongue 231 extends out when the door is opened, and the phenomenon that the inclined tongue 191 collides the door frame due to the anti-insertion of the inclined tongue assembly 19 when the door is closed can be avoided. When the triangular tongue connecting member 233 retracts, the third unlocking member 24 can rotate counterclockwise under the action of the torsion spring to separate from the second connecting portion 2134, and the anti-insertion rotation member 211 abuts against the inclined tongue connecting member 193 under the action of the anti-insertion torsion spring 215, so that the anti-insertion of the inclined tongue assembly 19 is realized.

The locking and unlocking processes of the lock body 10 according to the present invention are described below, wherein the locking process is divided into an electric locking process and a manual locking process, and the unlocking process is divided into an electric unlocking process and a manual unlocking process.

1. Locking process

Referring to fig. 8, after the door is closed, the latch tongue 191 retracts into the housing 11, extends out of the housing 11, and extends into the latch tongue hole, the triangular latch tongue 231 retracts into the housing 11, so that the triangular latch tongue connecting member 233 retracts, the triangular latch tongue connecting member 233 is separated from the third unlocking member 24, and the anti-insertion rotating member 211 abuts against the latch tongue connecting member 193 under the action of the anti-insertion torsion spring 215, thereby achieving the anti-insertion of the latch tongue assembly 19.

During the electronic locking, driving motor 142 (fig. 2) starts and drives first driving piece 144 (fig. 2) and rotates, and first driving piece 144 drives first driving piece 133 and rotates, and first driving piece 133 drives stirring piece 131 again and rotates, stirs and moves the piece 131 and directly drives main spring bolt subassembly 12 (fig. 1) and stretches out outside casing 11, has promoted the drive efficiency of drive assembly 14 (fig. 1), has reduced the consumption of drive assembly 14, realizes energy-conservation. After the oblique bolt 191 extends into the bolt hole, the anti-plugging of the oblique bolt assembly 19 is realized, the oblique bolt connecting piece 193 cannot move, so that the oblique bolt 191 cannot retract into the shell 11 even under the action of external force after extending into the bolt hole, the main bolt 123 is always matched with the bolt hole, the rotation of the driving motor 142 can drive the main bolt 123 to extend out, the probability of the stalling of the driving motor 142 is reduced, and the power consumption of the driving motor 142 is reduced.

Referring to fig. 1 and fig. 2, during manual locking, rotation of the key drives the lock cylinder 18 to abut against the second linkage member 17 and push the second linkage member 17 to move along the Y direction, so as to push the second driving member 15 to rotate counterclockwise, the second driving member 15 rotates counterclockwise to drive the second transmission member 135 to rotate clockwise, and the toggle member 131 also rotates clockwise, so as to drive the main bolt assembly 12 to extend out of the housing 11, thereby achieving manual locking of the lock body 10.

2. Unlocking process

Referring to fig. 9, during electric unlocking, the driving motor 142 (fig. 2) controls the driving motor 142 to start according to the opening signal, the driving motor 142 starts and drives the first driving member 144 (fig. 2) to rotate, the first driving member 144 drives the first driving member 133 to rotate, the first driving member 133 drives the first unlocking member 137 to rotate, and the first unlocking member 137 drives the anti-insertion rotating member 211 to separate from the latch bolt connecting member 193, so that the effect of electric unlocking is achieved. When the first transmission member 133 continues to rotate, the toggle member 131 is driven to rotate, and the toggle member 131 directly drives the main bolt assembly 12 (shown in fig. 1) to retract from the outside of the housing 11, so that the power consumption of the driving assembly 14 is reduced, and the electric unlocking is realized.

Referring to fig. 10, during manual unlocking, rotation of the key drives the lock cylinder 18 to abut against the first linkage 16 and push the first linkage 16 to move along the Y direction, the first linkage 16 pushes the second unlocking piece 22 to rotate counterclockwise, and the second unlocking piece 22 rotates counterclockwise to drive the anti-insertion connecting piece 213 to move along a direction opposite to the Y direction, so that the anti-insertion connecting piece 213 drives the anti-insertion rotating piece 211 to separate from the latch bolt connecting piece 193, thereby achieving the effect of manual unlocking. In addition, the movement of the first linkage member 16 along the Y direction will also push the second driving member 15 to rotate clockwise, the clockwise rotation of the second driving member 15 will drive the second transmission member 135 to rotate counterclockwise, and the toggle member 131 will also rotate counterclockwise, so as to drive the main bolt assembly 12 (fig. 1) to retract from the housing 11, thereby realizing the manual unlocking of the lock body 10.

After the door is opened, the triangular tongue connecting piece 233 extends out to drive the third unlocking piece 24 to rotate clockwise, the rotation of the third unlocking piece 24 drives the second connecting part 2134 (fig. 8) to move in the direction opposite to the direction Y, so that the anti-insertion connecting piece 213 drives the anti-insertion rotating piece 211 to separate from the inclined tongue connecting piece 193, the effect of extending out the triangular tongue 231 to remove the anti-insertion is realized, the phenomenon that the inclined tongue 191 collides the door frame due to the anti-insertion of the inclined tongue component 19 when the door is closed is avoided, and the state diagram of the lock body after the door is opened is shown in fig. 6.
