A handle mechanism with fingerprint recognition function

Abstract

The invention provides a lever handle mechanism with a fingerprint recognition function. The lever handle mechanism comprises a shell plate and a lever handle body. The lever handle body comprises a holding segment and an inserted connection segment with a cavity formed inside. The first end of the inserted connection segment is connected with the holding segment, the second end of the inserted connection segment stretches into the shell plate and is connected with square steel through a steering assembly, and the first end of the inserted connection segment is provided with fingerprint collection module. A pressure spring connected with the square steel and a wire used for transmitting fingerprint information are arranged in the cavity, the pressure spring is arranged in the middle, and the wire is eccentrically arranged. Based on the above structure, on one hand, the square steel can be matched with most door thicknesses by means of the telescopic characteristic of the pressure spring, and universality of the lever handle mechanism is improved; and on the other hand, the pressure spring and the wire are arranged in the cavity of the inserted connection segment, the pressure spring is arranged in the middle, the wire is eccentrically arranged, by means of the design, the space of the cavity is fully utilized, meanwhile, the problem that the wire freely rotates along with the lever handle body, and consequently the wire is twisted and damaged is avoided, and the service life of the lever handle mechanism is prolonged.

Description

technical field [0001] The invention relates to the technical field of fingerprint locks, in particular to a handle mechanism with a fingerprint identification function. Background technique [0002] With the development of science and technology, many locks with fingerprint unlocking function have appeared on the market. The handle mechanism of this lock is usually equipped with a fingerprint identification area for fingerprint input, and the inside of the handle mechanism is equipped with a wire for transmitting fingerprint information. . [0003] At present, there are generally two types and arrangements of wires: [0004] One is the wire in the form of an RVV cable. This type of wire is cylindrical in shape and arranged on the center line inside the handle mechanism. Therefore, when the handle is rotated arbitrarily, it will not drive the wire to rotate, making it difficult for the wire to rotate. damage and have a longer service life. However, this arrangement of wir...

Problems solved by technology

However, this arrangement of wires will take up too much internal space of the handle mechanism, resulting in the short length of the square steel also arranged inside the handle mechanism, which cannot adapt to various door thicknesses, thereby reducing the weight of the handle mechanism. Versatility

[0005] The other is a wire in the form of an FPC circuit board. This wire is in the shape of a sheet and is arranged on one side of the handle mechanism. Therefore, when the handle is rotated arbitrarily, the wire will be driven, and because the sheet-shaped wire Not resistant to folding, therefore, the form and arrangement of the wires are easily damaged and the service life is short
