Description

A fingerprint lock that is easy to use at night

technical field

The utility model relates to the technical field of fingerprint locks, in particular to a fingerprint lock that is convenient to use at night.

Background technique

Fingerprint lock is an intelligent lock, which is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology.

Fingerprint authentication is convenient, fast and accurate. With the popularization of technology and the development of smart homes, more and more people have begun to choose fingerprint locks. The existing fingerprint locks do not have the night light function. Difficulty opening doors.

Utility model content

The purpose of the utility model is to solve the disadvantage that the fingerprint lock in the prior art does not have the function of night light and cannot easily open the door in the dark, and proposes a fingerprint lock that is easy to use at night.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A fingerprint lock that is easy to use at night, comprising a lock body, a handle is arranged on the lock body, a side wall of the lock body is slidably fitted with a sliding cover, and a groove is formed in the lock body along the side wall, and the groove of the groove is provided with a groove. A fingerprint screen is arranged on the bottom, and light-emitting diodes are respectively arranged on the side walls of the two sides of the groove of the lock body.

Preferably, the sliding cover is located outside the fingerprint screen, and the groove is covered by the sliding cover.

Preferably, the bottom of the sliding cover is provided with a point contact, and the groove bottom of the groove is provided with a point contact at a position corresponding to the point contact.

Preferably, the sliding cover is a light-transmitting plate.

Preferably, the light emitting diode is electrically connected to a power source.

Preferably, the electrical contacts and the electrical contacts are located on the connection circuit between the light-emitting diode and the power supply.

The beneficial effect of the utility model is that: the fingerprint lock proposed by this solution solves the problem that the fingerprint lock does not have the function of night light, and the door cannot be easily opened in the dark. When the fingerprint lock is used, under normal circumstances, the sliding cover At the bottom, the point contact piece is connected with the point contact head, which can ensure that the light-emitting diodes are energized and keep the lights on, which is convenient for opening the door at night, with novel design and good practicability.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

In this embodiment, referring to Figures 1-2, a fingerprint lock for nighttime use includes a lock body 1, a handle 2 is provided on the lock body 1, and a sliding cover 3 is slidably fitted on the side wall of the lock body 1. The sliding cover 3 is a The light-transmitting plate, the lock body 1 is provided with a groove inward along the side wall, the bottom of the groove is provided with a fingerprint screen 4, the sliding cover 3 is located on the fingerprint screen 4, and the groove is covered by the sliding cover 3, and the lock body 1 is located on the fingerprint screen 4. The side walls on both sides of the groove are respectively provided with light-emitting diodes 5, the light-emitting diodes 5 are electrically connected to the power supply, the bottom of the sliding cover 3 is provided with a point contact 6, and the bottom of the groove is at a position corresponding to the point contact 6 A point contact piece 7 is provided, and the point contact head 6 and the point contact piece 7 are located on the connection circuit between the light emitting diode 5 and the power supply.

Specific working principle: Under normal circumstances, the slide cover 3 covers the fingerprint lock 4. In this state, the point contact 6 is connected to the point contact piece 7, and the light-emitting diode 5 is connected to the power supply. In the power-on state, the light-emitting diode 5 keeps At the same time, since the sliding cover 3 is light-transmissive, even in the dark, the human eye can easily see the specific position of the fingerprint lock, and then open the sliding cover 3, the fingerprint lock can be used. The door is opened, even if the point contact 6 and the point contact piece 7 are disconnected at this time, the light-emitting diode 5 is in a power-off state, and does not hinder the door. 6 is connected to the point contact piece 7, and the light-emitting diode 5 is connected to the power supply, where the lighting state is maintained.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
