[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in the description of the present application are only for the purpose of describing specific embodiments and are not used to limit the present application.

[0031] Such as Figure 1-2As shown in the figure, an embodiment of the present utility model is: The door lock device includes a locking component 1 and a control component 2 which are connected to each other. The locking component 1 and the control component 2 are both installed inside the door panel, and the lock opening is arranged on the door frame. Handles are arranged on both the front and back sides of the control component 2, and the two handles are respectively located on the inner and outer sides of the door, and the control component 2 can be operated from both sides. The locking component 1 includes: a locking seat 11, a pull rod 12, a lock tongue seat 13, a locking arm 14, a connecting rod 15 and a spring 16. The locking seat 11 is arranged on the right side of the control component 2; the pull rod 12 is horizontally slidably arranged inside the locking seat 11 and is connected to the control component 2; the lock tongue seat 13 is arranged at the left end inside the locking seat 11; the left end of the locking arm 14 is rotatably arranged inside the lock tongue seat 13, and its right end extends out of the lock tongue seat 13 for cooperating with the lock opening to lock the door. The upper end of the connecting rod 15 is rotatably connected to the right end of the locking arm 14, and its lower end is rotatably connected to the left end of the pull rod 12. The spring 16 is sleeved on the pull rod 12 for keeping the pull rod 12 moving towards the lock tongue seat 13. In this embodiment, both the locking arm 14 and the connecting rod 15 are two and are symmetrically arranged on the upper and lower sides of the axis of the pull rod, and can be locked up and down through the lock opening.

[0032] When locking is required, push the door panel to move leftward so that the locking arm 14 is inserted into the lock opening. The right end of the locking arm 14 moves downward under the constraint of the lock opening, pushes the pull rod 12 to move rightward through the connecting rod 15, and simultaneously compresses the spring 16. When the locking arm 14 enters the inner cavity of the lock opening, the locking arm 14 loses the constraint, the spring 16 resets, the right end of the locking arm 14 extends out and cooperates with the lock opening to lock; when unlocking, drive the control component 2 to move by pulling the handle. The control component 2 drives the pull rod 12 to slide horizontally rightward. The pull rod 12 drives the bottom end of the connecting rod 15 to move rightward. The connecting rod 15 drives the right end of the locking arm 14 to move downward and separates from the lock opening to achieve unlocking.

[0033] In this application, the control component 2 drives the pull rod 12 to move, the pull rod 12 drives the locking arm 14 to move through the connecting rod 15, and by restricting the first end of the locking arm 14 to rotate inside the lock tongue seat 13, the connecting rod 15 drives the second end of the locking arm 14 to retract or extend out of the lock tongue seat 13, so as to achieve locking or unlocking between the sliding door and the door frame. By installing handles on both sides of the control component 2, the unlocking method of this lock is the same as that of the traditional revolving door, and it can be operated on both sides of the door, and the structure is simple and reliable, which is very convenient.

[0034] In one embodiment, as Figure 2-3As shown in the figure, the control component 2 includes: a housing 21, a driving disk 22, and a swing arm 23. The housing 21 is arranged at the right end of the locking seat 11. The driving disk 22 is rotatably arranged inside the housing 21. The right end of the swing arm 23 is rotatably arranged on the disk surface of the driving disk 22 and is not concentric with the driving disk 22. The left end of the swing arm 23 is rotatably connected to the right end of the pull rod 12. When the driving disk 22 rotates, the pull rod 12 is pulled to move rightward through the swing arm 23. The position of the swing arm on the driving disk can be set as required, and different positions can make the movement range of the pull rod different. According to the rotation direction of the driving disk, the handle can be limited, such as only being able to rotate upward or downward.

[0035] In one embodiment, as Figure 2 shown, a sliding seat 17 is arranged at the right end inside the locking seat 11. The pull rod 12 is slidably connected to the sliding seat 17, and the sliding seat 17 restricts the pull rod 12 to move along the horizontal direction.

[0036] In one embodiment, as Figure 4 shown, a spring seat 18 is arranged on the left side of the pull rod 12. The spring 16 is sleeved on the pull rod 12 between the sliding seat 17 and the spring seat 18. When the pull rod 12 moves rightward, the spring seat 18 moves rightward and cooperates with the sliding seat 17 to compress the spring 16.

[0037] In one embodiment, as Figure 2 shown, a limiting platform 19 is arranged on the right side of the lock tongue seat 13. The limiting platform 19 abuts against the left end of the pull rod 12 to limit the leftward movement range of the pull rod 12.

[0038] In one embodiment, as Figure 2 shown, a driving hole 221 runs through the center of the driving disk 22 in the front - rear direction. The driving hole 221 is used to dock with the handle. The handle is installed on the door panel, and the rotating shaft of the handle matches the driving hole 221 to drive the driving disk 22 to rotate.

[0039] In one embodiment, as Figure 3 shown, a through - hole 211 is opened on one side of the housing 21 close to the locking seat 11. The through - hole 211 is used for the right end of the pull rod 12 and the left end of the swing arm 23 to pass through, facilitating the docking during their installation.

[0040] In one embodiment, as Figure 3 shown, a shaft seat 212 is arranged inside the housing 21. The rotating shaft of the driving disk 22 is rotatably connected to the shaft seat 212, and the driving hole 221 runs through the middle of the rotating shaft.

[0041] In one embodiment, as Figure 1-2As shown in the figure, sliding grooves 111 are respectively formed on the front and rear sides of the locking seat 11. The pull rod 12 and the connecting rod 15 are rotationally connected through a pin shaft 20. The pin shaft 20 is slidably connected with the sliding groove 111, which is used to limit the left end of the pull rod 12 and cooperate with the sliding seat 17 to restrict the movement direction of the pull rod 12.

[0042] It should be noted that the above technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope described in the description of the present utility model; moreover, for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
