[0042] It can be understood that when unlocking, the knob 500 drives the rotating of the first rotating shaft 410, thereby driving the rotating of the driving member 400, so as to drive the driving part 420 to push the abutting part 230, thereby driving the rotating of the transmission member, and further driving the retraction of the bolt 300, so as to realize the unlocking. After the knob 500 is released, the driving member 400 is reset under the elastic action of the first torsion spring 430.

[0043] Further, according to some embodiments of the utility model, Figures 2 to 3According to some embodiments of the utility model, the unlocking mechanism further comprises a transmission rod 600, the transmission rod 600 is vertically arranged in the inner cavity, the abutting portion 230 and the abutting portion 230 respectively abut the two sides of the transmission rod 600, when the driving part 400 rotates, the abutting portion 420 can push the transmission rod 600, so that the transmission rod 600 pushes the abutting portion 230, when the transmission part 200 moves upwards, the abutting portion 230 keeps in contact with the transmission rod 600.

[0044] It can be understood that, in actual use, because the abutting portion 230 moves upwards while rotating with the transmission part 200, the abutting portion 230 and the abutting portion 420 may be separated, which affects the use performance, therefore, the utility model embodiment drives through the transmission rod 600 arranged between the abutting portion 420 and the abutting portion 230, and the abutting portion 230 keeps in contact with the transmission rod 600, which ensures the continuity and reliability of the transmission in the whole unlocking process.

[0045] Further, referring to Figure 2 According to some embodiments of the utility model, the end of the abutting portion 230 in contact with the transmission rod 600 is provided with a notch, the notch is adapted to the shape of the transmission rod 600, so that the transmission rod 600 is not easy to be separated from the abutting portion 230, which ensures the continuity and reliability of the transmission, and can reduce friction and wear.

[0047] Further, referring to Figures 2 to 5 According to some embodiments of the utility model, the door lock device further comprises a safety mechanism, the safety mechanism comprises a blocking part 700 and a driving part, the blocking part 700 is arranged in the lock tongue 300 and can move up and down, the upper part of the blocking part 700 is provided with an upwardly extending blocking rod 710, the upper part of the lock tongue 300 is provided with a first through hole 320, the blocking rod 710 passes through the first through hole 320, and the blocking rod 710 abuts the first rotating part 210 close to one side of the lock tongue 300, the driving part is arranged in the lock tongue 300, when the lock tongue 300 retracts, the driving part can drive the blocking part 700 to move downwards to make the blocking rod 710 retract.

[0048] It can be understood that by setting the blocking piece 700 movable up and down in the lock tongue 300, without triggering the unlocking mechanism, the blocking piece 700 extends the blocking rod 710 out of the first through hole 320 and abuts against the side of the first rotating part 210 close to the lock tongue 300, so that as long as the first rotating part 210 remains stationary, the lock tongue 300 cannot be retracted. When the unlocking mechanism is triggered, the transmission member 200 rotates to drive the first rotating part 210 to rotate, the first rotating part 210 pushes the driven part 310 to retract the lock tongue 300, and in this process, the driving member moves the blocking piece 700 downward to retract the blocking rod 710, so that the lock tongue 300 is no longer blocked during retraction and can be fully retracted, thereby achieving reliable security function through simple structure principle, simplifying the process and reducing the manufacturing cost.

[0049] Further, referring to Figure 4 and Figure 5 According to some embodiments of the present application, the lower part of the blocking piece 700 is provided with a downwardly extending guide rod 720, and the lower part of the lock tongue 300 is provided with a corresponding second through hole 330, and the guide rod 720 is slidingly arranged in the second through hole 330.

[0050] It can be understood that the guide rod 720 can limit and guide the blocking piece 700, avoiding the blocking piece 700 from shaking left and right, so that the up and down movement of the blocking piece 700 is more stable and smooth.

[0051] Further, referring to Figure 4 and Figure 5 According to some embodiments of the present application, the blocking piece 700 is provided with a sliding groove, and in a direction away from the first rotating part 210, the sliding groove comprises a first extension section 730 and a second extension section 740 connected in sequence, the width of the first extension section 730 in the up and down direction is constant, the width of the second extension section 740 in the up and down direction gradually increases in a direction away from the first extension section 730, the driving member comprises a lever 800, one end of the lever 800 is connected to the main lock body 100, the other end of the lever 800 is provided in the sliding groove, and when the lock tongue 300 is retracted, the lever 800 can move from the first extension section 730 to the second extension section 740.

[0052] It can be understood that the initial state of the push rod 800 is located in the first extension section 730 and remains stationary, and the actual position can be determined according to actual conditions, which is not limited here. When the first rotating part 210 pushes the driven part 310 to retract the lock tongue 300, the blocking rod 710 will also move with the first rotating part 210 during this process, and will retract the first through hole 320 under the driving of the push rod 800 at the same time, until the first through hole 320 is completely retracted, so that the lock tongue 300 can be completely retracted. By setting the first extension section 730 with a constant width, when the push rod 800 moves inward relative to the lock tongue 300 along the first extension section 730, the blocking piece 700 remains stationary relative to the lock tongue 300, so that the blocking rod 710 does not gradually retract the first through hole 320, but moves a certain distance with the first rotating part 210, until the push rod 800 enters the second extension section 740 relative to the lock tongue 300 from the first extension section 730. Since the width of the second extension section 740 gradually increases, the blocking piece 700 gradually descends under the action of its own gravity, so that the blocking rod 710 gradually retracts the first through hole 320 and finally completely retracts the first through hole 320 to leave the first rotating part 210, so that the lock tongue 300 can be completely retracted. The above structure can provide a buffer time for the lock tongue 300, so that the lock tongue 300 does not have a loose feeling when unlocking due to the too fast retraction of the blocking rod 710, thereby improving the user's experience. On the other hand, by providing a buffer time, if the unlocking mechanism is interrupted within the buffer time, the lock tongue 300 can be quickly reset under the elastic action of the second torsional spring 360, reducing the movement of the parts, thereby reducing the friction between the parts, increasing the service life by reducing the loss.

During maintenance, the user can also manually push the part of the push rod 800 extending out of the guide groove 340, thereby releasing the connection between the blocking rod 710 and the first rotating part 210.

[0057] Further, referring to Figure 5 According to some embodiments of the present application, the locking tongue 300 is provided with a limiting groove 350 away from the inner wall of the inner cavity, and the blocking piece 700 is inserted into the limiting groove 350 away from the inner cavity, thereby playing a limiting and fixing role, which can avoid the shaking or offset of the blocking piece 700 during use, improve the structural reliability, and ensure the use performance.
