Description

J type key double flute anti-theft lock

Technical field:

The utility model is a kind of door lock that relates to, lock field, the theftproof lock that is made of J type key and double flute lock core.

Background technology:

For a long time, the structure and the shape of most of lock adopt traditional mode always, promptly are single groove lock cores, the yi word pattern key, and the key glossal canal exposes.The too simple lock core structure of this kind; can see very intuitively from the key glossal canal that exposes and the billiards structure of groove in-core portion to adopt some simple means, simple tools just can be opened and be destroyed; theftproof performance completely loses, and does not have due safeguard protection effect.Such as the tool used in crime of reporting in the news or capture up, be exactly that some simply make instrument by hand.So simple tools just can cause great damage to property to constituting a serious threat with the main body of lockset as safety device, the visible importance that improves the theftproof performance of lock.

Summary of the invention:

Goal of the invention of the present utility model is exactly the deficiency that overcomes existing theftproof lock, provides a kind of rational in infrastructure, can obviously improve the theftproof performance of lock, the theftproof lock that can effectively stop artificial means to be destroyed again.

Goal of the invention of the present utility model mainly is achieved by following technical proposals, and described theftproof lock is to be made of J type key and double flute lock core two parts.Wherein said J type key is changed the yi word pattern outward appearance of traditional key, is designed to the J type key of being made up of key mobile jib and key tongue that is J type structure.It is elongated that its performance is embodied in the key mobile jib, and key tongue and key mobile jib angulation make the arm of force elongated, and arm of force bending is not with supporting J type key when unblanking, and is difficult to balance and firmly unblanks with the judgement key, thereby effectively improved the theftproof performance of locking.Described double flute lock core is broken through existing single impression die formula, has designed the double flute pattern of straight cutting key and key glossal canal, wherein, only sees that in appearance the straight cutting key can't see the key glossal canal, makes the key glossal canal have hidden function.The billiards structure of key glossal canal inside just is hidden in the inboard and can't see, and can't see and does not just know with which type of instrument of which type of method just can open, and has also fundamentally effectively improved the theftproof performance of lock.In other words, bypass destructive means of destruction, have only the supporting J type key of use just can open.And no matter this theftproof lock is to compare with existing theftproof lock on volume or the weight not have much differences, is not also having much differences with traditional marble mechanical lock core aspect making and controlling.Therefore, the utility model great advantage is the visual determination ability that hidden function that built-in key glossal canal and key tongue have has effectively stoped the people, and J type key makes the arm of force elongated, arm of force bending, instrument beyond the key is good at finding strong point balance firmly to unblank, thereby has improved theftproof performance.J type key double flute lock core is made up of J type key mobile jib and key tongue, and mobile jib is the J type with the key tongue and directly links together into an integral body.The double flute lock core contains straight cutting key and built-in stealthy key glossal canal, and J type key inserts key after rotate into built-in stealthy key.

Description of drawings:

Accompanying drawing 1 is the product form schematic diagram of the utility model J type key; Accompanying drawing 2 is that the utility model double flute lock core is with outer volume morphing schematic diagram; Accompanying drawing 3 are Fig. 2 E-E to sectional view.The built-in key glossal canal of 10-mobile jib 11-key tongue 12-straight cutting key 13-

The specific embodiment:

Below by embodiment, and in conjunction with the accompanying drawings, structure of the present utility model is done to describe further.

Specific embodiments: key and lock core are produced J type shape and double flute pattern by special equipment, from only seeing the straight cutting notch in appearance.J type key enters from lock core straight cutting key when unblanking, and key rotates to built-in key glossal canal more then, and key is up carried, and twists and unblanks.Thereby make the utility model technology effectively reach aforementioned goal of the invention.
