The housing 1 may be in a cuboid shape. The first accommodation slot 3 and the second accommodation slot 4 may be symmetrically disposed within the housing 1. The first accommodation slot 3 and the second accommodation slot 4 may be in a cuboid shape. In actual applications, the housing 1 may be disposed at a position at the center line of the doorframe of the sliding door, may be an upper frame of the doorframe, or may be a lower frame of the doorframe. A size of the housing 1, a size of the first accommodation slot 3, and a size of the second accommodation slot 4 may be designed according to actual use. The housing 1, being fixed at a position at the center line of the doorframe, may be configured to detect whether a position where two slideable door leaves of the sliding door are joined stays at a position at the center line.
The first primary lock catch 5 is rotatablely disposed within the first accommodation slot 3. The second primary lock catch 6 is rotatablely disposed within the second accommodation slot 4. Refer to FIG. 4, FIG. 4 is a schematic structural diagram of a first primary lock catch 5 and a second primary lock catch 6 according to the application.
It may be learned from FIG. 4 that the first primary lock catch 5 may include a first rotating shaft 51 and a first locking component 52. The first rotating shaft 51 and the first locking component 52 may be respectively disposed at two ends of the first primary lock catch 5. The first primary lock catch 5 may further include a first locking groove 53. The first locking groove 53 may be disposed at one end of the first primary lock catch 5 that is close to the first locking component 52. The first rotating shaft 51 may be fixed within the first accommodation slot 3. By using the first rotating shaft 51, the first primary lock catch 5 may be rotated out from the first accommodation slot 3.

The second locking groove 63 may be disposed at one end of the second primary lock catch 6 that is close to the second locking component 62. The second rotating shaft 61 may be fixed within the second accommodation slot 4. By using the second rotating shaft 61, the second primary lock catch 6 may be rotated out from the second accommodation slot 4. When locking is not required, the first primary lock catch 5 and the second primary lock catch 6 are rotatable, which makes the first primary lock catch 5 be able to be disposed within the first accommodation slot 3, and makes the second primary lock catch 6 be able to be disposed within the second accommodation slot 4.

The first secondary lock catch 7 is connected to the first primary lock catch 5 in an attractable manner, and the second secondary lock catch 8 is connected to the second primary lock catch 6 in an attractable manner. In actual applications, the housing 1 is disposed at a position at the center line of the doorframe of the sliding door. The first secondary lock catch 7 and the second secondary lock catch 8 may be respectively disposed on two slideable door leaves. The first primary lock catch 5 and the first secondary lock catch 7 attract each other, and the second primary lock catch 6 and the second secondary lock catch 8 attract each other. In this way, two movable door leaves are locked at a position at the center line of the doorframe. A manner in which the first primary lock catch 5 and the first secondary lock catch 7 attract each other, and a manner in which the second primary lock catch 6 and the second secondary lock catch 8 attract each other are not specifically defined in the application. The middle seam scanning mechanism 2 may include a transmitting end 21, a first sensing end 22, and a second sensing end 23. The transmitting end 21 may be disposed on the housing 1 at a center position. The first sensing end 22 may be disposed on the first secondary lock catch
7. The second sensing end 23 may be disposed on the second secondary lock catch 8. In actual applications, a distance from the transmitting end 21 to the first sensing end 22 and a distance from the transmitting end 21 to the second sensing end 23 are obtained to calculate a distance difference between the two distances. When the distance difference is zero, it indicates that the position where the two slideable door leaves are joined coincides with the center line of the doorframe, which avoids a case that a gap exists between the slideable door leaf and a fixed door leaf during a process of sliding the slideable door leaf in actual applications. A method for obtaining the distance may be selected according to actual requirements. For example, the transmitting end 21 may emit infrared rays, and the first sensing end 22 and the second sensing end 23 may receive the infrared rays. The distance is measured through the infrared rays. A specific manner is not defined in the application.
The automatic calibration and locking device for a sliding door may further include an indicator 14. The indicator 14 may be electrically connected to the transmitting end 21. When the distance difference is zero, the indicator 14 may be lighted, to indicate that the slideable door leaf has been calibrated and a locking operation may be continued.

It may be learned from the foregoing technical solutions that the automatic calibration and locking device for a sliding door provided in the application includes a housing 1, a middle seam scanning mechanism 2, a first accommodation slot 3, a second accommodation slot 4, a first primary lock catch 5, a second primary lock catch 6, a first secondary lock catch 7, a second secondary lock catch 8, a slider 9, a linkage mechanism 10, a first ejection mechanism 11, a second ejection mechanism 12, and an indicator
14. The first accommodation slot 3 and the second accommodation slot 4 are respectively disposed within the housing 1. The middle seam scanning mechanism 2 includes a transmitting end 21, a first sensing end 22, and a second sensing end 23. The first primary lock catch 5 and the first ejection mechanism 11 are disposed within the first accommodation slot 3. The first primary lock catch 5 is separably connected to the first ejection mechanism
11. The second primary lock catch 6 and the second ejection mechanism 12 are disposed within the second accommodation slot 4. The second primary lock catch 6 is separably connected to the second ejection mechanism 12. In actual applications, the distance from the transmitting end 21 to the first sensing end 22 and the distance from the transmitting end 21 to the second sensing end 23 are obtained to calculate a distance difference between the two distances.
When the distance difference is zero, the indicator 14 is lighted.
The slider 9 is slid to enable the linkage mechanism 10 to drive the first primary lock catch 5 to be detached from the first ejection mechanism 11, and drive the second primary lock catch 6 to be detached from the second ejection mechanism 12. The detached first primary lock catch 5 and second primary lock catch 6 respectively attract the first secondary lock catch 7 and the second secondary lock catch 8. The automatic calibration and locking device for a sliding door provided in the application can enable the position where the two slideable door leaves of the sliding door are joined to coincide with the center line of the doorframe.
In this way, the sliding door is automatically calibrated, and meanwhile, the sliding door is locked, being convenient and practical.
For similar parts between the embodiments provided in the application, reference may be made to each other.
The specific implementations described above are merely some examples under a general concept of the application, and do not constitute any limitation to the protection scope of the application.
For a person skilled in the art, any other implementations derived according to the solutions of the application without an effective effort all fall within the protection scope of the application.
