Document Type and Number:
WIPO Patent Application WO/2020/024990
Kind Code:
A1
Abstract:
A keyless blind-opening mechanical combination lock, relating to the technical field of mechanical combination locks. A rotating disc (6) and an inserting disc (7) are coaxially sleeved on a rotating wheel shaft (5), a password rotating wheel (3) is rotatably sleeved on one end of the rotating wheel shaft (5), and the inner end part of the password rotating wheel (3) passes through a vertical plate (1) and is connected to the rotating disc (6); a bolt (12) arranged horizontally is provided on the rotating disc (6), and a plurality of forward inserting grooves (703) and backward inserting grooves (701) is correspondingly provided on the inserting disc (7); a rotating disc positioning mechanism (11) is provided on one side of the rotating disc (6), and marking clamping grooves (601) in butt joint with the inner side of the positioning mechanism are provided on the outer circumferential end surface of the rotating disc (6). According to the present invention, a form that a rotating disc and an inserting disc overlapped coaxially are inserted to each other is used, inserting grooves comprise forward inserting grooves and backward inserting grooves, and a bolt enters the inserting grooves to drive the inserting disc to rotate forwards or backwards, so that the difficulty in arbitrarily opening a combination lock is increased; by means of cooperation of a positioning mechanism, the safety and anti-theft performance of the combination lock can be further improved.
