Thus, the locking protrusion 41 of the first locking seat 40 presses the first movable member 51 of the cable 50 when the number lock mechanism 20 is disposed at a locked state to lock the first movable member 51 of the cable 50, and the locking protrusion 83 of the second locking seat 80 presses the second movable member 52 of the cable 50 when the key lock mechanism 60 is disposed at a locked state to lock the second movable member 52 of the cable 50.
The housing 10 has a first side formed with a first chamber 11 connected to the slideway 15 to receive the number lock mechanism 20 and the first locking seat 40 and a second side formed with a second chamber 13 connected to the slideway 15 to receive the key lock mechanism 60 and the second locking seat 80. The first chamber 11 of the housing 10 has a lower portion formed with a mounting hole 12 for mounting a press button 30 which is located under the number lock mechanism 20, so that when the number lock mechanism 20 is disposed at an unlocked state, the press button 30 can be pressed to adjust the code of the number lock mechanism 20. The second chamber 13 of the housing 10 has an upper portion formed with a limit flange 14.
The slideway 15 of the housing 10 has a first end formed with a first locking hole 16 for locking the first movable member 51 of the cable 50 and a second end formed with a second locking hole 17 for locking the second movable member 52 of the cable 50. The first locking hole 16 of the housing 10 has a side formed with an arc-shaped recessed limit portion 160 to limit the first movable member 51 of the cable 50 by a push force of the locking protrusion 41 of the first locking seat 40, and the second locking hole 17 of the housing 10 has a side formed with an arc-shaped recessed limit portion 170 to limit the second movable member 52 of the cable 50 by a push force of the locking protrusion 83 of the second locking seat 80. The passage 18 of the housing 10 is located at a mediate portion of the slideway 15 between the first locking hole 16 and the second locking hole 17. Thus, each of the first movable member 51 and the second movable member 52 of the cable 50 is extended into and outwardly from the slideway 15 of the housing 10 through the passage 18 of the housing 10.
The number lock mechanism 20 includes a number lock core 21, a mandrel 22 movably mounted on the number lock core 21, and an elastic member 24 mounted on the mandrel 22 and biased between the number lock core 21 and the first locking seat 40 to push the locking protrusion 41 of the first locking seat 40 toward the first movable member 51 of the cable 50.
The first locking seat 40 is located above the number lock mechanism 20 and mounted on the mandrel 22 of the number lock mechanism 20. Thus, when the number lock mechanism 20 is disposed at an unlocked state, the mandrel 22 of the number lock mechanism 20 is movable relative to the number lock core 21, so that the first locking seat 40 is movable relative to the number lock mechanism 20 between a first position as shown in
The second locking seat 80 is rotatably mounted in the second chamber 13 of the housing 10 and located above the limit flange 14 of the housing 10. The second locking seat 80 has a side formed with a flattened face 82. Thus, the second locking seat 80 is rotatable relative to the housing 10 between a first position as shown in
The cable lock further comprises a drive member 70 rotatably mounted in the second chamber 13 of the housing 10 and having a first end connected to the second locking seat 80 to rotate the second locking seat 80 and a second end connected to and rotated by the key lock mechanism 60, and an elastic member 72 biased between the second locking seat 80 and the drive member 70 to push the locking protrusion 83 of the second locking seat 80 toward the second movable member 52 of the cable 50. The second locking seat 80 has a bottom formed with a fixing hole 81. The first end of the drive member 70 is provided with a drive post 71 inserted into the fixing hole 81 of the second locking seat 80 so that the second locking seat 80 is rotatable by the drive member 70. The second end of the drive member 70 is formed with a fixing bore 72. The key lock mechanism 60 includes a key lock core 62 inserted into the fixing bore 72 of the drive member 70 so that the drive member 70 is rotatable by the key lock core 62 of the key lock mechanism 60. Thus, when the key lock core 62 of the key lock mechanism 60 is rotated by a specific key, the drive member 70 is rotated by the key lock core 62 of the key lock mechanism 60 to rotate the second locking seat 80.
As shown in
As shown in
Accordingly, the cable 50 of the cable lock is locked and unlocked by the number lock mechanism 20 and the key lock mechanism 60 respectively, so that a user can lock and unlock the number lock mechanism 20 to open and close the cable lock, and the inspector of the customs can use a specific key to lock and unlock the key lock mechanism 60 to open and close the cable lock, thereby facilitating the user and the inspector of the customs operating the cable lock. In addition, the specified key is held by the inspector of the customs, so that the inspector can directly unlock the key lock mechanism 60 of the cable lock by the specified key so as to open and check the luggage locked by the cable lock without having to break the cable lock for checking the luggage.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
