Further, as shown in fig. 3, 4, 5 and 6, the cable controller 20 includes two or more pull rods 25 axially arranged along the rotating shaft 24; the rotating shaft 24 comprises a cylindrical rotating shaft main body 241, and clamping grooves 242 are spirally distributed on the surface of the rotating shaft main body 241 along the axial direction; the spiral distribution angle of the clamping grooves 242 is less than 360 degrees, the number of the clamping grooves 242 is larger than or equal to the number of the pull rods 25, and the axial distance of the clamping grooves 242 is equal to the distance of the pull rods 25;
the pull rod 25 is provided with a rotating shaft hole 252 which is in clearance fit with the rotating shaft 24, one side of the rotating shaft hole 252 is provided with a tenon 251 which can be meshed with the clamping groove 242, and the tenon 251 enables the pull rod 25 to rotate relative to the rotating shaft 24 in a single direction.
In this embodiment, an eight-way cable controller (eight lock bodies can be controlled by one cable controller) is taken as an example, and a fourth-way cable is taken to control the opening and closing of the lock bodies for explanation:
in this example, the number of the pulling cables 18 is eight, each of the locking slots 242 on the rotating shaft 24 rotates clockwise by 45 degrees and is uniformly distributed, the locking slot 242 corresponding to the first pulling cable 18 is set to be 0 degree, that is, the angle of the fourth locking slot 242 corresponding to the fourth pulling cable 18 is 135 degrees.
The fourth way of stay cable controls the unlocking of the lock body as follows:
1. the rotating shaft 24 rotates counterclockwise by 225 degrees (360 minus 135 degrees), so that the fourth pull rod 25 corresponding to the fourth pull cable 18 is aligned with the fourth engaging groove 242, and at this time, the engaging tenon 251 of the fourth pull rod 25 is engaged with the fourth engaging groove 242. Since the latch 251 allows the pull rod 25 to rotate only in one direction relative to the rotation shaft 24 (in this case, the rotation shaft rotates clockwise in one direction, and in other embodiments, different rotation directions can be set), when the rotation shaft 24 rotates counterclockwise, any one of the pull rod 25 and the cable 18 will not be driven to move.
2. The rotating shaft 25 rotates clockwise by 5 degrees, the pull rod 25 rotates to drive the pull cable 18 to rotate the corresponding lock hook 11, and unlocking is achieved.
Further, as shown in fig. 1, 3 and 4, a second spring 26 and a position sensor are disposed between the pull rod 25 and the bracket 22. The second spring 26 stabilizes the cable 18 in the unlocked state of the shackle 11, and the position sensor is used to monitor the position of the pull rod 25.
In the unlocked state, the latch hook 11 is lifted up, and the pull rod 25 is pulled up by the second tension spring 26. When the cabinet door is locked, the lock hook 11 resets and hooks the retaining ring 17, the pull rod 25 is pulled down by the inhaul cable 18, and whether the cabinet door is closed or not can be known through the position sensor.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the protective scope of the present patent claims.
