High-strength U-shaped combination lock

Abstract

The invention relates to a high-strength U-shaped combination lock, which includes a U-shaped lock bar and a lock body, the lock body includes a metal tubular lock body shell, a combination lock assembly and a lock gate assembly, and the combination lock assembly includes several groups of combination wheels Components, mandrel, the combination lock component is arranged in the lock body shell. In the present invention, the lock body and the lock block are arranged separately, and the lock block is slidably arranged in the groove on the lock body in the radial direction. When the U-shaped lock is damaged by external force prying, Driven by the U-shaped lock rod, the lock block moves slightly in the radial direction and leans against the inner wall of the lock housing to transmit the external force to the lock housing, and the lock housing is usually made of high-strength metal materials , so the overall tensile strength is greatly enhanced.

Description

technical field [0001] The invention relates to the field of locks, more specifically, it relates to a high-strength U-shaped combination lock. Background technique [0002] A U-shaped combination lock is a common lockset, which is often used on non-motor vehicles such as bicycles and two-wheeled electric vehicles. U-shaped coded locks usually include a U-shaped lock bar and a lock body. The lock body includes a coded lock assembly, a lock gate and a lock body shell. The coded lock assembly includes several groups of coded wheel assemblies and mandrels. It includes an annular password wheel and an annular positioning wheel, and the annular password wheel and the annular positioning wheel form a slidable and circumferential linkage connection. The annular combination lock component is axially positioned and rotatably arranged on the mandrel, and when the combination is correct, the mandrel can move axially to unlock. Because in the existing U-shaped locks, the lock gate par...

Problems solved by technology

Because in the existing U-shaped locks, the lock gate part matched with the bayonet on the U-shaped lock rod is usually integrated with other parts of the lock gate body, and most of them are castings, when the U-shaped lock is pried and pulled by an external force When it is destroyed, the force will be concentrated on the small part of the lock that matches the bayonet, resulting in damage; in addition, the existing U-shaped lock middle lock housing has a window that allows all the combination wheels to be exposed at the position corresponding to the combination lock assembly , also reduces the mechanical strength of the U-shaped lock, so it is difficult to meet the requirements of higher anti-theft strength
