The door lock is an indispensable device in daily life. It is installed on the door panel of the building entrance and exit. Generally speaking, the opening and closing action of the door panel at the door frame is performed through the door lock bolt. The door frame is achieved by the expansion and contraction of the mouth piece; even if the door lock is to be further locked so that the door panel cannot be easily opened by the outdoor intruder, the lock tongue must be reliably abutted to ensure the lock tongue. The locking state can be formed after the door lock is extended, thereby achieving the security that the lock should have and the effect of being forcibly invaded.

The groove is inclined at an angle to the longitudinal direction of the door lock, and the two ends of the groove respectively form an upper locking portion and a lower locking portion, and the guiding pin of the locking tongue is disposed in the groove Inside the slot, the guiding pin is moved inside the groove by the upper and lower displacement of the transmission member. When the guiding pin is located at the upper locking portion, the locking tongue is driven to extend the door lock and remains locked. If the guide pin is located in the lower locking portion, the locking tongue will be driven to retract the unlocking lock, and the unlocking state is released; another prior art US Patent No. 7,431,354 B2 discloses a guide locking door lock, Controlling a guiding transmission member through a matching of an auxiliary sensing tongue and a stopping member, the groove of the guiding transmission member being sleeved on a pin of a locking tongue, by the guiding transmission member Moving up and down to drive the locking tongue to actuate and maintain the locking, and the specific driving of the guiding transmission member 7 is performed by a spring to convey the force of the auxiliary sensing tongue to the starting lock to the stopping member, so that the stopping member When the recess of the guiding transmission member is disengaged, the guiding transmission member is displaced downward due to the loss of the stopping member, thereby driving the locking tongue to act, and the other spring is used for resetting the auxiliary sensing tongue, and the spring is used for resetting the auxiliary sensing tongue It is installed in the same axial direction inside the spring.

After the flap is received, the tongue block 31 sequentially abuts against the sleeve 32, the inductive tongue linkage piece 40 and the convex ring portion 331 of the tongue post 33 to overcome the elastic force of the return spring 34, thereby making the induction tilt The tongue 30 can be retracted into the interior of the lock case 10, and when the door panel is closed to the position, the tongue 20 is affected by the elastic force of the return spring 34, And the lock case 10 is extended to the corresponding portion of the mouth piece of the door frame.

In addition, when the tongue piece 31 and the tongue piece 22 can be retracted into the interior of the plate member 12 at the same time, if the tongue piece 22 has not entered the corresponding portion of the mouth piece of the door frame due to the force of the first torsion spring 13 The protrusion 211 is caused to be locked in the recess 61. As shown in FIG. 4, the present invention still fails to enter the locked state, so that even if the tongue piece 22 and the tongue piece 31 are simultaneously retracted into the plate member 12, It is still necessary to wait for the tongue piece 22, and the tongue piece 31 which is acted upon by the return spring 33 to enter the corresponding position of the mouthpiece piece to enter the locked state.

Referring to FIG. 6 , if the straight tongue 50 enters the corresponding position of the mouth piece of the door frame, and the straight tongue 50 cannot be fully extended due to external factors, the creation can still enter the quasi-locking state. Since the second lock rivet 112 abuts against the top abutment groove 65, even if the drive post 52 is located in the middle of the travel of the drive groove 64 and does not reach the position of the lock, the straight tongue 50 can still remain extended. The state does not retreat into the interior of the lock case 10, so that the author performs the first forced lock function of the door lock.

Since the straight tongue 50 is on the moving line of the first straight straight tongue rivet 811 of the round straight tongue 80, as shown in FIG. 8, therefore, only when the creation is in the locked state of the straight tongue 50, Straight tongue 50 does not hinder the movement of the first round straight tongue rivet 811, please refer to FIG. 6 and FIG. 7 at the same time, the user can rotate the lock button in the room, or insert the lock head to rotate outside, thereby driving The push rod 71 of the lock shaft 70 is pushed against the third straight tongue rivet 813 to displace the body piece 81, and the cylinder 82 can extend out of the lock case 10 to achieve the locking of the round tongue 80 of the present invention. status.

On the other hand, if the user wants to release the locked state of the creation, the user can unlock the lock shaft 70 by using the rotation of the lock shaft 70. Referring to FIG. 8, the push column 71 is pushed against the abutment portion 66.
