Description
技术领域 Technical field
本发明涉及一种组合钥匙，特别是一种无轴连接的可变组合加密机械钥匙。 The present invention relates to a combination key, and more particularly to a variable combination encryption mechanical key without a shaft connection.
背景技术 Background technique
近几年，许多锁具制造商越来越重视防盗锁具的安全性和防盗性的研发，如机械防盗锁、电子智能防盗锁。但是几乎所有的机械防盗锁都是配备有一套应急开启的机械钥匙，也就是说，锁具的防盗性能就算是非常高，只要拿到对应的开启钥匙，那这个锁具的安全性能实际上就是零。这就带来一个新的问题，如果避免机械钥匙被偷走或被复制。在如今的科技条件下，钥匙的复制轻而易举。因此，提供一款无法复制的机械钥匙对于钥匙丢失或被盗带来的安全隐患具有非常重要的意义。
In recent years, many lock manufacturers have paid more and more attention to the development of anti-theft locks for security and anti-theft, such as mechanical anti-theft locks and electronic intelligent anti-theft locks. However, almost all mechanical anti-theft locks are equipped with a set of mechanical keys that are opened in an emergency. That is to say, the anti-theft performance of the locks is very high. As long as the corresponding opening key is obtained, the safety performance of the lock is actually zero. This brings up a new problem if you avoid the mechanical key being stolen or copied. In today's technological conditions, the copying of keys is a breeze. Therefore, providing a mechanical key that cannot be copied is very important for the safety risks caused by lost or stolen keys.
申请人烟台三环科技有限公司于2014年2月19日递交的一项发明专利申请，其专利名称为可变组合机械钥匙，申请号为201410055233.1，现已公布并进入实审程序。该发明专利提供了一种组合机械钥匙，具体结构是由轴串接能够形成匙牙的多个匙型零件。后续阶段继续研发过程中，发现轴接的结构存在结构相对复杂的问题。继而想设计一种不用轴接的组合加密钥匙。因此，在本申请中，又针对该技术研发了另一种无轴连接的组合结构。
Applicant Yantai Sanhuan Technology Co., Ltd. submitted an invention patent application on February 19, 2014. The patent name is a variable combination mechanical key, the application number is 201410055233.1, which has been published and entered the actual trial procedure. The invention patent provides a combined mechanical key, the specific structure being a plurality of spoon-shaped parts that can form a key by a shaft. In the subsequent stage of the development process, it was found that the structure of the shaft joint has a relatively complicated structure. Then I want to design a combined encryption key that does not need to be connected. Therefore, in the present application, another combined structure without a shaft connection has been developed for this technology.
