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.
