Abstract

A mechanical vehicle lock allowing a password to be changed comprises a ring-shaped lock main body. The ring-shaped lock main body is provided with a first end and a second end that can be opened and closed. In a locked state, the first end and the second end of the ring-shaped lock main body are fixed with each other by means of a lock catch. In an unlocked state, the first end and the second end are separated from each other in a released manner. The first end is provided with an insertion rod portion (20). One end of the insertion rod portion (20) is provided with a first clip portion (21), and the second end is provided with a lock case (10). The lock case (10) is provided with a hollow portion. A push button (50), a locking clip block (40) and a locking clip block return elastic element (401) are sequentially disposed on the lock case (10) from the top to the bottom in a manner of corresponding to the hollow portion. The push button (50) is connected to a password-type lock cylinder structure used for controlling the push button (50) to be free of being pushed at will. By means of a password-type lock cylinder structure (60), after unlocking is carried out by the password wheel set, the password is automatically, mechanically and regularly changed, so that loss of a vehicle due to a fixed password is avoided. Also provided are an unlocking control system and an unlocking method supporting the mechanical vehicle lock allowing a password to be changed.

Abstract

A mechanical combination lock allowing a password to be automatically changed comprises a lock case (10), a movable shaft (61) disposed in the lock case (10) and capable of performing axial reciprocation, and more than one password wheel set (62) mounted on the movable shaft (61). The movable shaft (61) is disposed in a manner of extending along the direction of an umbrella shaft (20). The password wheel set (62) comprises a shifting wheel (621), rotary wheels (622), password wheels (623), and a first elastic element (624). A second elastic element (67) is disposed on the movable shaft (61). A third elastic element is connected to the front side of the rotary wheel (622). A first skewed tooth (6211) of the shifting wheel (621) is in linkage with a second skewed tooth (6221), so as to control the rotary wheels (622) to rotate. An unlocking stop block (1202) extending along the direction of the movable shaft (61) is disposed in the lock case (10). When a lock needs to be unlocked, a correct password is obtained by means of rotations, and the password wheels (621) are linked with the rotary wheels (622) to rotate until unlocking grooves (6223) thereof right face unlocking stop blocks (1202), so that the movable shaft (61) can be pulled to move. Also provided are an unlocking control system and an unlocking control method for the mechanical combination lock allowing a password to be automatically changed. By means of the structure of the mechanical combination lock, after unlocking is carried out based on the password wheel set, the password is automatically, mechanically and regularly changed.

Abstract

An antitheft umbrella allowing a password to be automatically changed, and an unlocking control system thereof and a method therefor. The antitheft umbrella comprises an umbrella handle (10), an umbrella shaft (20), and an umbrella stand (30). A first clip portion (31) is disposed at one end of the umbrella stand (30). The umbrella handle (10) is provided with a hollow portion. A push button (50), an umbrella stand clip block (40) and an umbrella stand clip block return elastic element (401) are sequentially disposed on the umbrella handle (10) from the top to the bottom in a manner of corresponding to the hollow portion. The push button (50) is connected to a password-type lock cylinder structure (60) used for controlling the push button (50) to be free of being pushed at will. The password-type lock cylinder structure (60) comprises a movable shaft (61) and more than one password wheel set (62) mounted on the movable shaft (61). When the umbrella needs to be opened, a correct password is obtained by means of rotations, and the password wheels (623) are linked with rotary wheels (622) to rotate until unlocking grooves (6223) thereof right face unlocking stop blocks (1202). By means of the ingenious design of the password-type lock cylinder structure (60), the password is automatically, mechanically and regularly changed after the umbrella is opened by means of the password wheel set (62), and accordingly, undesirable phenomena such as umbrella losing and theft caused by a fixed password are avoided, thereby facilitating umbrella management and maintenance. In addition, the push button slide control structure for opening and closing the umbrella is ingenious and reasonable in design, the linkage is stable, and the using reliability is good.
