Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an electronic lock. Background Art

[0002] An electronic password lock is an electronic product that controls the circuit or chip operation (access control system) through password input, thereby controlling the closing of a mechanical switch to complete the task of unlocking and locking. There are many types of electronic password locks, including simple circuit products and cost-effective products based on chips. The most widely used electronic password locks are based on chips and are implemented through programming. In the field of security technology prevention, electronic password locks with anti-theft alarm functions replace traditional mechanical password locks, overcoming the shortcomings of mechanical password locks with fewer passwords and poor security performance, greatly improving the password locks in both technology and performance.

[0003] However, the commonly used electronic locks on the market have a large exposed part of the lock body after installation, which is not beautiful and easy to be damaged, and has low security. In addition, the electronic locks on the market use button batteries installed inside, but due to the small capacity of button batteries, they need to be replaced frequently, and it is often inconvenient to replace them.

[0004] Therefore we propose an electronic lock to solve the above problems. Utility Model Content

[0008] As a preferred technical solution of the utility model, the lock bottom cover and the battery frame are installed by means of an inner shell spring.

[0009] As a preferred technical solution of the utility model, a nut is provided on the upper surface of the fixing sleeve and the nut is installed in cooperation with the lock head, and the scraper and the nut are installed in cooperation with each other through screws and spring washers.

[0010] As a preferred technical solution of the present utility model, the battery in the battery frame is a cylindrical battery.

[0011] As a preferred technical solution of the utility model, the electronic lock has a virtual password input function. You can enter garbled characters before and after the correct password to cover up the real password. A total of 15 digits can be entered. If there is a continuous password that is the same as the set password, the password verification is passed.

[0012] The beneficial effects of the utility model are as follows: the utility model is equipped with an installation bushing, which can hide most of the lock body into the door panel, and has better concealment. After the lock body is installed, the lock body is smaller from the outside, and the appearance is more concise and beautiful. The protruding part of the lock body is smaller, and it is relatively safer in case of malicious damage. Since the battery frame is installed inside the lock body, the lock body can remain integrated without the need for an additional battery box, and the overall volume can be kept small; and the cylindrical battery has more power than ordinary button batteries, which makes the electronic lock have a longer service life and reduces the frequency of battery replacement. The battery frame cooperates with the flip-up battery cover, and the battery can be installed, replaced and repaired simply by flipping it open, which improves the convenience of the user. By setting a virtual password, the electronic lock can be made safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS
