Abstract

A woven strap lock structure including a male fastener and a female fastener. One end of the male fastener has an insertion tongue formed with a latch hook edge. The female fastener is composed of a seat body and a teeterboard type latch plate pivotally connected with the seat body. A key-unlocked unit is disposed in a non-insertion end of the seat body for controlling a push button. The other end of the seat body is formed with an insertion opening corresponding to the insertion tongue. The seat body is formed with an operation room communicating with the insertion opening, in which the latch plate is mounted. A numeral unlocking unit is disposed on the latch plate. One end of the latch plate is formed with an engaging edge corresponding to the latch hook edge of the insertion tongue for latching with the latch hook edge. The other end of the latch plate is a press end which can be pressed into the seat body to make the end of the latch plate with the engaging edge turned upward. The push button is disposed at the press end and controlled by the numeral unlocking unit. In a natural state, one end of the push button is resiliently engaged on a support section of the support member. When the numeral unlocking unit is unlocked or the key-unlocked unit is operated by a key, the support section releases the push button, permitting the latch plate to be pressed and unlatched.

Claims

1. A woven strap lock comprising:

a first snapping member;

a strap connected with the first snapping member;

a second snapping member connected with the strap and detachably connected to the first snapping member;

a key-unlocked unit disposed on the first snapping member and being capable of locking or unlocking the second snapping member via a key; and

a numeral unlocking unit disposed on the first snapping member and being capable of locking or unlocking the second snapping member via a code.

2. The woven strap lock of claim 1, wherein the key-unlocked unit comprises a lock core operable by the key, and a support member which can be driven by the lock core to abut against or depart from the numeral unlocking unit.

3. The woven strap lock of claim 2, wherein the numeral unlocking unit comprises a controlling member that can be driven to abut against or depart from the key-unlocked unit when the code of the numeral unlocking unit is entered.

4. The woven strap lock of claim 1, wherein the first snapping member comprises:

a first seat body; and

a second seat body movably mounted on the first seat body wherein movement of the second seat body is controlled by either one of the key-unlocked unit and the numeral unlocking unit.

5. The woven strap lock of claim 4, wherein the key-unlocked unit is disposed on the first seat body and the numeral unlocking unit is disposed on the second seat body.

6. The woven strap lock of claim 5, wherein the key-unlocked unit comprises a lock core operable by the key, and a support member driven by the lock core to abut against or depart from the numeral unlocking unit.

7. The woven strap lock of claim 6, wherein the numeral unlocking unit comprises a controlling member which can be driven to abut against or depart from the key-unlocked unit when the code of the numeral unlocking unit is entered.

8. A lock comprising:

a first seat body;

a snapping member detachably connected with the first seat body;

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

a numeral unlocking unit disposed on the second seat body and including a controlling member;

a key-unlocked unit disposed on the first seat body and including a support member and a lock core operable by a key;

wherein the support member of the key-unlocked unit is configured to be driven by the lock core to abut against or depart from the numeral unlocking unit;

the controlling member of the numeral unlocking unit is configured to be driven to abut against or depart from the key-unlocked unit when a code of the numeral unlocking unit is entered; and

thereby movement of the second seat body is controlled by either one of the key-unlocked unit and the numeral unlocking unit.

9. The lock of the claim 8 comprising a number-changing rod defined with a front section disposed in a hole of the first seat body, and a rear section connected to the numeral unlocking unit for changing a code of the numeral unlocking unit.
