Abstract:
Steel cable lock structure with internal multidirectional locking effect, comprising a housing, a cable winding device, a locking device and a steel cable clutch controller, wherein:an interior space is defined in the housing, an upper end of the space forming a first chamber, a lower end of the space forming a second chamber, a cable head home hole and a cable head latch hole being formed through the housing; the cable winding device including a reel pivotally disposed in the second chamber of the housing, an outer circumference of the reel being formed with multiple ratchets, the steel cable being wound on the reel, after wound, the steel cable extending through the cable head home hole out of the housing, whereby the steel cable can be drawn out and then inserted into the cable head latch hole of the housing, an outer extending end of the steel cable being connected with an engaging head; the locking device is fitted in the first chamber of the housing for controlling unlocking/locking operation, whereby when the engaging head is inserted into the cable head latch hole, the locking device locks or unlocks the engaging head; and the steel cable clutch controller is disposed in the second chamber of the housing between the locking device and the cable winding device, said steel cable lock structure being characterized in that the steel cable clutch controller includes a lower end press button, a two-way abutting bar, a button bar and a dog, the lower end press button being disposed in the housing corresponding to a lower end press button hole thereof, the lower end press button being formed with a recessed wall, a front end of the lower end press button extending out of the housing, a rear end of the lower end press button extending into the housing to pivotally connect with the dog, a rear end of the button bar being pivotally connected with the lower end press button, an upper end of the two-way abutting bar being fitted in the cable head latch hole of the housing, whereby when the engaging head is inserted, the upper end of the two-way abutting bar is pressed by the engaging head to slide in the latch hole, an inner end of the two-way abutting bar being pivotally connected with the front end of the button bar, the front end of the dog being formed with claws and pivotally disposed at rear end of the lower end press button, an oblique slot being formed on at least one of the pivotally connecting sections of the dog and the lower end press button, the rear end of the dog being pivotally connected in the second chamber of the housing near a position where the cable winding device releasing and retracting the steel cable, whereby when the two-way abutting bar is pressed by the inserted engaging head, the two-way abutting bar cooperates with the button bar to engage in the recessed wall of the lower end press button so as to stop the lower end press button from further moving into the housing and at the same time, the oblique slot drives and guides the dog to make the claws of the dog stop the cable winding device from rotating so that the steel cable cannot be moved out of or into the housing, whereby when the engaging head is inserted and locked, the press button, cable winding device and steel cable are synchronously effectively locked.
