DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Referring to FIGS. 1 to 3, the combination lock of the present invention comprises a body 10 and a shackle 14, wherein the shackle 14 has the first end pivotably and movably connected to the body 10, and the second end of the shackle 14 is removably inserted into the body 10. A keybox 15 is located in the body 10 and includes a room 152 for receiving keys or the like therein. A cover 151 is pivotably connected to the body 10 and is able to close the room 152 for safety reason by any known methods.

[0027] The combination lock has a combination device connected to the body 10 and includes a first control panel 11, a second control panel 12 and a switch button 13. The first control panel 11 has multiple digit wheels 111 rotatably connected thereto. The second control panel 12 has multiple number buttons 121 and multiple function buttons 122. The number buttons 121 has 0 to 9 respectively marked thereon. The first control panel 11 and the second control panel 12 control the shackle 14 and the cover 151. The switch button 13 can be switched to a first position P1 to activate the first control panel 11, and the switch button 13 can be switched to a second position P2 to activate the second control panel 12.

[0028] As shown in FIG. 4, the first method for operating the combination lock comprises:

[0029] a step of setting combinations: a first combination being set to the first control panel 11, a second combination being set to the second control panel 12, the second combination being a spare combination; and

[0030] a step of switching the switch button 13: when switching the switch button 13 to the first position P1, the shackle 14 is operated and the cover 151 is opened relative to the keybox 15 by inputting the first combination or the second combination from the first control panel 11, when switching the switch button 13 to the second position P2, the shackle 14 is operated and the cover 151 is opened relative to the keybox 15 by inputting the first combination or the second combination from the second control panel 12.

[0031] The second method is that the first control panels 11 includes a first combination, and the second control panel 12 includes a second combination. The second combination is a spare combination in case the first combination is forgotten. As shown in FIG. 5, when the switch button 13 is switched to the first position P1, the shackle 14 is operated and the cover 151 is opened relative to the keybox 15 by inputting the first combination from the first control panel 11. If the first control panel 11 is out of order or the first combination is forgotten, the switch button 13 is switched to the second position P2, the shackle 14 is operated and the cover 151 is opened relative to the keybox 15 by inputting the second combination from the second control panel 12. The first combination can be used as a primary combination and the second combination can be used as a secondary combination.

[0032] As shown in FIG. 6, the third method for operating the combination lock as described above comprises:

[0033] a step of setting combination: a first combination and a second combination being respectively set to the first control panel 11, and

[0034] a step of switching the switch button 13: when switching the switch button 13 to the first position P1, the shackle is operated by inputting the first combination from the first control panel 11, when switching the switch button 13 to the second position P2, the cover 151 is opened relative to the keybox 15 by inputting the second combination from the first control panel 11.

[0035] As shown in FIG. 7 which shows the fourth method, wherein the first control panel 11 in the third method can be replaced by the second control panel 12. That is to say, a first combination and a second combination are respectively set to the second control panel 12. When switching the switch button 13 to the first position P1, the shackle 14 is operated by inputting the first combination from the second control panel 12. When switching the switch button 13 to the second position P2, the cover 151 is opened relative to the keybox 15 by inputting the second combination from the second control panel 12.

[0036] FIG. 8 shows the fifth method, wherein a first combination is set to the first control panel 11, and a second combination is set to the second control panel 12. A first combined combination is defined by a combination of the first combination and the second combination. Similarly, a third combination is further set to the first control panel 11, and a fourth combination is further set to the second control panel 12. A second combined combination is defined by a combination of the third combination and the fourth combination.

[0037] When the switch button 13 is switched to the first position P1, the shackle 14 is operated by inputting the first combined combination from the first control panel 11 and the second control panel 12 respectively. When the switch button 13 is switched to the second position P2, the cover 151 is opened relative to the keybox 15 by inputting the second combined combination from the first control panel 11 and the second control panel 12 respectively. The first combined combination may be set to control the cover 151, and the second combined combination may be set to control the shackle 14.

[0038] As shown in FIG. 9, the sixth method for operating the combination lock as described above comprises:

[0039] a step of connection: connecting the second control panel 12 to an application (APP) of a smart phone, and

[0040] a step of setting a combination: setting a combination to the second control panel 12 by operating the application from the smart phone, the shackle 14 being operated and/or the cover 151 being opened relative to the keybox 15 by inputting the combination to the second control panel 12.

[0041] As shown in FIG. 10, the shackle 14 can also be operated and/or the cover 151 is opened relative to the keybox 15 by inputting the combination from the smart phone.

[0042] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
