Abstract

A strap lock comprises a female fastener, a male fastener, a key-unlocked unit and a numeral unlocking unit. The female fastener includes a first seat body and a second seat body movably mounted on the first seat body. The male fastener is detachably attached to the first seat body of the female fastener. Both the key-unlocked unit and the numeral unlocking unit are disposed on the second seat body. The strap lock can be unlocked by either one of the key-unlocked unit and the numeral unlocking unit.

Claims

1. A lock comprising:

a first seat body;

a second seat body movably mounted on the first seat body; and

a lock assembly disposed on the second seat body, and including a key-unlocked unit configured to control movement of the second seat body via a key, and a numeral unlocking unit configured to control the movement of the second seat body via a code; and

a fastener having an end detachably attached to one end of the first seat body;

wherein the fastener is allowed to be detached from the first seat body only when the second seat body is allowed to move by either one of the key-unlocked unit and the numeral unlocking unit.

2. The lock of claim 1, further comprising a strap;

the strap having one end connected with the other end of the first seat body;

the other end of the strap being adjustably attached to the fastener.

3. A strap lock having both a key-unlocked unit and a numeral unlocking unit that can be unlocked by either one of the key-unlocked unit and the numeral unlocking unit, comprising a female fastener and a male fastener;

the female fastener including a first seat body and a second seat body movably mounted on the first seat body;

the male fastener detachably attached to the first seat body of the female fastener; and

both the key-unlocked unit and the numeral unlocking unit being disposed on the second seat body.

4. A strap lock comprising:

a female fastener including a first seat body and a second seat body movably mounted on the first seat body;

a strap connected to the first seat body of the female fastener;

a male fastener having one end connected with the strap and the other end detachably connected to the first seat body of the female fastener; and

a lock assembly disposed on the second seat body and comprising a key-unlocked unit configured to control the movement of the second seat body via a key; and

a numeral unlocking unit configured to control the movement of the second seat body via a code.

5. The strap lock of claim 4, wherein the second seat body of the female fastener is allowed to teeter on the first seat body to release the male fastener from the female fastener when the code for the numeral unlocking unit is entered.

6. The strap lock of claim 4, wherein the strap is adjustably mounted on the male fastener to adjust a loop size defined by the strap.

7. The strap lock of claim 4, wherein the first seat body of the female fastener includes an insertion opening corresponding to an insertion tongue of the male fastener;

the insertion tongue is formed with a latch hook edge corresponding to an engaging edge of the second seat body of the female fastener;

the engaging edge of the second seat body is allowed to move in a first direction away from the latch hook edge so as to release the insertion tongue of the male fastener from the insertion opening of the female fastener when the code for the numeral unlocking unit is entered; and

the engaging edge moves in a second direction away from the latch hook edge so as to release the insertion tongue from the insertion opening when the key-unlocked unit is operated by the key.
