Description

Dragon lock

Technical Field

The invention belongs to a lockset, and particularly relates to a spring lock, a blade lock and a mechanical coded lock. On the basis of spring lock, blade lock and mechanical cipher lock, the main elements of them are organically combined together to form a new anti-theft lock which can not be opened technically, is suitable for modern lock industry development and can be combined with electronic lock.

Background

The lockset is a reliable anti-theft tool in the mind of people. However, few people who are not in the locking industry or the unlocking industry know that a security door can be opened silently and in seconds. This is not a problem with locks, but the lock design has not yet reached a level at which it is impossible to open it. Standards for the lock industry worldwide; a-level lock: opening as qualified, class B lock within 1 minute: opening within 5 minutes is acceptable, not in the super class B lock industry standard, but only a brand for some businesses. Advanced bank vault door mechanical combination lock, someone can open in 5 minutes 17 seconds, what key lock can exceed financial combination lock?

However, it is known that technical opening of a key lock requires the use of an unlocking tool. The key lock can not be technically opened by a technical unlocking master without an unlocking tool. The development of a lockset capable of preventing any unlocking tool from being technically unlocked is a great problem in the lockset industry. The dragon lock solves the world problem in the lock industry.

Disclosure of Invention

The invention aims to provide a method; the novel anti-theft door lock completely prevents technical unlocking, has stronger destructive resistance, can realize electric unlocking.

The technical scheme adopted for realizing the invention is as follows; it adopts main blade and auxiliary blade. The main blade is pushed by a strong spring, and the auxiliary blade is pushed by a weak spring. When locking, the main blade is pushed by the strong spring, so that the auxiliary blade is driven to lean to one side. In the process of unlocking by the key, the main blade is compressed and retracted by the key unlocking working surface, and the auxiliary blade extends out of the key unlocking working surface. This is different from the way in which the tumbler or blade moves during the unlocking process of the tumbler lock and blade lock currently in use. One is a combination of compression and extension of the blades from the origin; one is pure compression. The anti-theft performance is greatly improved relatively; more importantly, the blades are self-pinning. The principle of realizing the self-latching of the blade is to utilize a concave key slot. The blade is in the locking state, has occupied a part of concave groove, and at this moment, the unlocking means gets into from the other parts of concave groove, can't stir the blade, can only stir the blade when the blade occupies leave 0.3mm 1.2 mm's tip entering. We define the working space of the key within 3/5 of the recess groove, just the edge of the protruding part of the keyhole of the lock body, thus confirming that the blade moves beyond the protruding part of the keyhole of the lock body and the blade is in the locking state. Therefore, the unlocking tool can only enter from the closed frame formed by the blade and the key hole bulge on the lock body, and can only effectively stir the blade. The closed frame formed by the lock body keyhole and the blade is only 1.2mm by 3 mm. This 1.2mm by 3mm closed frame forms the primary blade self-locking. We reset the width of the first main blade which is accessed by the key to be 0.1-0.15mm wider than the width of the other main blades and the other auxiliary blades, and limit the opening position of the first main blade to be within one third of the closed frame, namely, the variable edge of the closed frame can reach 1 mm. I.e. 1.2mm by 1mm-1.2 by 0.6 mm. This is a further embodiment of the blade self-bolting. When the first main blade is not at the opening position, the first main blade is 0.1-0.15mm wider than other main and auxiliary blades, so that only the first main blade is in contact with the code block and cannot be in contact with other main and auxiliary blades, and the opening position cannot be found by shifting other main and auxiliary blades. Within the closed frame there are also 7-11 vanes, each of which in the following can restrict the frame even less, and can even cross close the frame. This makes any technical unlocking tool invalid except the curved bar formed by the key, and achieves the ultimate goal of preventing technical unlocking in the lock design.
