Description

Door lock

This creation is about a lock, especially about the mouth of a door lock.

The door lock is provided with a lock head on the door panel, and the lock head is embedded in an edge of the door panel. The lock head has a latch that can be extended from the lock head by a user and extends in a direction parallel to the door panel. A receiving port is formed on the door frame corresponding to the position of the locking head, and the locking bolt can be received in the receiving mouth when the locking bolt protrudes from the locking head. At this time, the door panel is fastened to the door frame, and if locked, the lock bolt cannot be retracted into the lock head. In other words, unless the lock can be retracted into the lock head, the lock bolt cannot be disengaged from the mouthpiece, so that the door panel is fixed and cannot be disengaged from the door frame, thereby achieving the purpose of locking the door.

Generally, the shape and size of the mouthpiece correspond to the shape and size of the bolt, so that the lock bolt can be tightly engaged in the mouth when the door panel is locked, so as to prevent the door panel from being slightly shaken after being locked. . However, since the latch and the mouth are tightly engaged, after being locked and unlocked multiple times, a gap may be gradually formed between the two due to wear. After a gap is formed between the lock bolt and the mouthpiece, as long as a slight airflow is generated indoors or outdoors, the door panel may be shaken, and the lock bolt and the mouthpiece are accelerated to wear. In addition, when the door panel is shaken, it is easy for the lock bolt to collide with the mouth to generate noise, which is unbearable for residents who like quiet or luxury houses.

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

Please refer to Figure 1 to Figure 4 first. The present invention proposes a mouthpiece for a door lock that is fixed to a door frame. The mouthpiece has a locking piece 10, a displacement seat 20, a fixing member 30, a screwing seat 40, a rod body 50 and an operating member 60.

The locking piece 10 is fixed on the door frame and is formed with a recessed portion 11. The lock bolt of the lock on the door panel can selectively accommodate the inside of the recessed portion 11. The locking piece 10 has a fixing portion 12 (shown in FIG. 4) which is fixed to the inner surface of the recess portion 11. In this embodiment, the fixing portion 12 is a screw hole.

The position of the displacement seat 20 is adjustably received in the recess 11. Specifically, the displacement base 20 is formed with two shielding portions 21, two side wall portions 22, and a bottom wall portion 23, respectively, from the outside to the inside.

The two shielding portions 21 are parallel to the bottom wall of the recessed portion 11 of the locking piece 10 and are respectively located at two ends of the displacement seat 20 and are respectively connected to the two side wall portions 22 and abut against the edge of the recess portion 11. The two side wall portions 22 are respectively parallel to the left and right side walls of the recess portion 11, and the spacing between the two side wall portions 22 is smaller than the spacing of the side walls of the recess portion 11. Therefore, after adjusting the position of the displacement seat 20, the side wall portion 22 and the side wall of the recess portion 11 can be 111 phases are abutted or spaced apart. The bottom wall portion 23 is parallel to the bottom wall of the recess 11 and is located between the two side wall portions 22. The bottom wall portion 23 is formed with an opening 231 and an adjustment groove 232. The adjustment groove 232 extends left and right, and the position of the adjustment groove 232 corresponds to the fixing portion 12 of the locking piece 10.

The fixing member 30 is disposed through the adjusting groove 232 of the displacement seat 20 and fixed to the fixing portion 12 of the locking piece 10 to selectively fix the position of the displacement seat 20. Specifically, in the embodiment, the fixing member 30 is a screw, and the screw body of the fixing member 30 can be screwed with the fixing portion 12 of the locking piece 10 after the screw body of the fixing member 30 passes through the adjusting groove 232, and the fixing member 30 and the locking piece After the screwing of 10, the screw head of the fixing member 30 can abut against the bottom wall portion 23 of the displacement seat 20 and abut against the displacement seat 20 to fix the position of the displacement seat 20.

The screw seat 40 is received in the recessed portion 11 of the locking piece 10 and is fixed to the rear side surface of the bottom wall portion 23 of the displacement seat 20. In the present embodiment, the screw seat 40 has two seat portions 41 which are respectively fixed to the left and right sides of the opening 231 of the displacement seat 20 . Both of the seat portions 41 may be formed with internal threads, but only one of them may be formed with internal threads.

The rod 50 is rotatably disposed in the recess 11 and penetrates and is screwed to the screw seat 40. The two ends of the rod 50 abut against the left and right side walls in the recess 11 respectively. Thereby, when the position of the displacement seat 20 is adjusted, the screw seat 40 can be restricted by the rod body 50 and moved relative to the rod body 50 to prevent the displacement seat 20 from coming off. In the present embodiment, the rod body 50 may have a threaded section extending from the one end of the rod body 50 toward the middle of the rod body 50 and screwed into the seat portion 41 formed with the internal thread. The cross-section of the portion of the rod 50 that is not threaded may be polygonal. In other embodiments, the rod body 50 can have two thread segments extending from the two ends of the rod body to the middle of the rod body 50 and screwed to the two seat portions 41 respectively.

The operating member 60 is formed with a through hole 61 so as to be sleeved on the rod 50; in other words, the operating member 60 is located on the rear side of the bottom wall portion 23 of the displacement seat 20. The shape of the through hole 61 is a polygon corresponding to the cross section of the rod body 50, so that the through hole 61 can be engaged with the rod body 50 to be pivoted in conjunction with the rod body 50. Further, the inner diameter of the through hole 61 is slightly larger than the rod 50, in other words, the operating member 60 is not tightly fitted over the rod 50, and thus can be moved in the longitudinal direction of the rod 50. In the present embodiment, the operating member 60 is located between the two seats 41, and the edge of the operating member 60 is serrated and exposed from the opening 231 of the displacement seat 20.

Through the above configuration, when the mouthpiece is attached, the position of the displacement seat 20 relative to the rod body 50 can be adjusted by rotating the operating member 60, and then the displacement seat 20 is placed in the recessed portion 11 of the locking piece 10. Next, the fixing member 30 is passed through the adjusting groove 232 of the displacement seat 20 and locked to the fixing portion 12 of the locking piece 10. At this time, the fixing member 30 abuts against the displacement seat 20, so that the position of the displacement seat 20 is fixed, and the door lock of the present invention is installed.

Next, please refer to FIG. 5 and FIG. 6 for a period of time. If the lock bolt of the lock or the displacement seat 20 of the mouth is worn or deformed, and the gap between the side wall portion 22 of the displacement seat 20 and the bolt is formed, The fixing member 30 is loosened rather than abutting against the displacement seat 20, and the position of the displacement seat 20 can be adjusted by rotating the operating member 60 until the side wall portion 22 of the displacement seat 20 can be brought into contact with the lock bolt when locked. In addition, adjustment can be made without removing the fixing member 30 during adjustment.

When the operating member 60 is rotated, the rod body 50 also rotates, but since the both ends of the rod body 50 abut against the two side walls of the recessed portion 11, the rod body 50 does not move. In contrast, since the screwing seat 40 is screwed with the rod body 50, the relative position of the screwing seat 40 and the rod body 50 changes after the rod body 50 rotates; and the displacement seat 20 and the screwing seat 40 are fixed. Therefore, the relative position of the displacement base 20 and the rod 50 also changes. In other words, the position of the displacement base 20 can be adjusted by rotating the operating member 60.

In other embodiments, if the operating member 60 is not provided, the user can use the tool with a tip (such as a small screw, a needle-nosed pliers, etc.) or a household item (such as a pen, a paper clip, etc.) to extend into the displacement seat 20. The opening 231 directly rotates the rod body 50, and the position of the displacement seat 20 can also be adjusted.

In summary, the present invention can adjust the position of the side wall portion 22 of the displacement seat 20 to the left and right to correspond to the position of the bolt by adjusting the displacement seat 20 of the recessed portion 11 of the locking piece 10, so that the displacement seat 20 can Fitted to the lock bolt. In addition, even after a period of use, the lock bolt or the displacement seat 20 is deformed, and a gap is formed between the lock bolt and the displacement seat 20, and the lock bolt can be reattached by adjusting the displacement seat 20. Therefore, through the implementation of this creation, it is possible to avoid the sway of the locked rear door panel and the noise generated by the collision with the door frame after the door panel is shaken.
