CN2509294Y - Composite key of electronic lock - Google Patents

Abstract

The utility model relates to a compound key for the electronic lock which comprises a key which comprises a key handle and a key body; the key handle is provided with a code circuit; the key body comprises two metal conductors separated by the insulating layer; and the two metal conductors are connected with the code circuit. The utility model is characterized in that the key has the function as a mechanical lock; as the key handle is provided with a code circuit and has no power, the metal conductor gets through the code circuit with the power in the lock body; therefore the utility model is durable, saves electricity, consumes no electricity when unlocking, has a low mutual opening ratio, is not easy to be decoded, and is convenient to be made and arranged compared with the prior electronic code lock.

Description

The complex key of electronic lock

Technical field

The utility model relates to lock, particularly relates to a kind of complex key of electronic lock.

Background technology

Lock is very close with people's daily life, work, when you pass in and out door (dwellings and office), steering vehicle (automobile and motorcycle etc.), and open and close safety cabinet, drawer, wardrobe etc., all from not come into contacts with lock, therefore kind, the pattern of lock are very many.Existing machinery lock mutual opening rate is opened by master key easily than higher.And also there are following shortcoming in existing cipher remote control formula motorcycle or automotive lock: the one, because environment for use is poor, mechanical shock causes frequency departure and out of control especially greatly easily; The 2nd, need frequently to change battery in the key; The 3rd, burglar's available electron device intercepts signal reaches the password purpose; The 4th, trouble is installed.

Summary of the invention

The utility model is in order to overcome the defective of prior art, provides a kind of key to contain cryptochannel and the complex key in charged source not.The technical scheme of the complex key of described electronic lock is: the key of being made up of the shank of the key and key body, cryptochannel is installed in the shank of the key, it is characterized in that described key body is made up of two isolated metallic conductors of insulating layer, two metallic conductors and cryptochannel link.A kind of concrete combination form of its described key body is cylindrical or the inner core of the metallic conductor of rectangle, and inner core has insulating layer outward, and the outside of insulating layer is again the skin of metallic conductor, and the inner core of metallic conductor and skin link with cryptochannel.The another kind of pattern of key body is conductor metal sheet, insulating layer, conductor metal sheet, and promptly the centre of two outside conductor metal sheets is separated by insulating layer, and two conductor metal sheets and cryptochannel link.It is prior art that cryptochannel is installed in key, and the kind pattern of cryptochannel can be a lot, but prior art charged source simultaneously all.The utility model has cryptochannel but not charged source, and do not have the loop, and by key body as the power circuit conducting in positive and negative electrode conductor and the lock body, so key is to open mechanical lock to use, as circuit electrode conducting usefulness, decoding circuit is the same with prior art still to be installed in the lock body again.Compared with the prior art advantage is that key does not contain power supply, and is durable in use; The power consumptive province, not power consumption when not unblanking; Mutual opening rate is low, and theftproof performance is good, the intercept signal difficulty; Make, install laborsaving.

The specific embodiment

The utility model relates to field of lockset, particularly relate to key, the key that had both possessed mechanical lock, again as the parts of electronic password lock, so by the shank of the key and key that key body is formed, cryptochannel is installed in the shank of the key, main feature is that key body is by the insulating layer of being separated by between two metallic conductors, two metallic conductors and cryptochannel link, and cryptochannel is a class prior art.The combination form of metallic conductor and insulating layer is a lot, can be inside and outside, about (about comprising, front and back) etc.As Fig. 1, Fig. 3 and shown in Figure 5 be inside and outside metallic conductor, and be cylindrical structural (can adopt rectangle in actual product is cuboid), the inner core 1,22 that metallic conductor is arranged, inner core has insulating layer 2,18 outward, the outside of insulating layer is again the skin 3,17 of metallic conductor, and the inner core of metallic conductor and skin can link by lug plate 6,24 and cryptochannel 4,25.Fig. 2, Fig. 4 be about or deserve to be called down metallic conductor, be insulating layer 32 in the middle of its conductor metal sheet 31,33, the conductor metal sheet links through lug plate 34 and cryptochannel, this conductor metal sheet also can be made half round post.Fig. 5 is a key and a kind of pattern that cooperates of lock core, be the inner core 22 outer front and back insulator caps 16,20 that insulating layer 18 and two are arranged, preceding insulator cap 16 is chewed 15 with signal and is linked to each other, signal is chewed through prap 13 to power supply, and key drive insulated connecting piece 12 and eccentric shaft 11 and lock core body 14, mechanical lock is opened.Back insulator cap 20 provides separates the contact chip 19,21 that inside and outside metallic conductor is installed.In actual product, key is a lot of with the pattern that cooperates of lock core.
