Portable fingerprint lock

Abstract

The invention discloses a portable fingerprint lock. The portable fingerprint lock comprises a face shell, a bottom shell, a steel wire and a fingerprint identifier, wherein LED indicator lamps and atransparent lampshade are arranged on the periphery of the fingerprint identifier. A circuit board assembly is arranged inside the fingerprint identifier, and a lithium battery is arranged between thecircuit board assembly and the bottom shell. The circuit board assembly is provided with an MCU processor and a buzzer. A speed reducing motor is arranged on one side of the face shell, a cam is arranged on a shaft of the speed reducing motor, the speed reducing motor is internally provided with a lock clamp which can rotate from the lock hole in a rotating mode, and the lower part of the lock clamp is provided with a torsion spring. One end of a lock hole is a round hole, the other end of the lock hole is a slightly-narrow flat hole, and the flat hole communicates with the round hole. One end of the steel wire is fixed on the surface shell and the bottom shell, the other end of the steel wire is fixedly connected with a spherical head, the spherical head is inserted into the lock hole, and the spherical head is clamped into the semi-arc end of the lock hole. A sliding block is arranged on the upper portion of one side of the lock clamp, and the two ends of the sliding block are of anarch structure, the front end of the sliding block abuts against the lock clamp, and the rear end of the sliding block abuts against a stop block arranged in a fixing seat groove. The portable fingerprint lock is novel and unique in structure, simple, convenient and practical, low in cost and high in reliability.

Description

technical field [0001] The invention relates to the field of locks, in particular to a portable fingerprint lock. Background technique [0002] There are many types of existing portable locks, which can be summarized as follows: tumbler locks, code disc locks, and electronic locks. Among them, electronic locks include: remote control locks, induction locks, combination locks, and fingerprint locks. [0003] Although the traditional tumbler lock has many users, it has the disadvantages that the key is easy to lose, and it is easy to be copied and has a low safety factor. Though code disc lock has exempted from the trouble of carrying key, there is the defect that number is easy to see through, unsafe. Although the remote control lock does not have the defects of the tumbler lock and the dial lock, it has the defects of requiring a remote control or a smart phone to install an APP and relying on wireless networks including WIFI, mobile networks, and Bluetooth. Although indu...
