Tapered end also can be positioned at after the back veneer, or on the doorframe in being positioned at.Tapered end can be in the hole or the either direction up and down of recess install in vertical state with door.Protector can be positioned at before the tapered end or be connect with the couplet on the door and form by one or more anti-drilling headkerchieves and/or one or more anti-drilling sheet on the hole.Hole on the door, hole or recess all can have different geometries, all can porosely go up protector.Convex cover can be stretched out by the panel of door to protrude and forms, and also can fixedly get in addition or connects with door is movable.Convex cover can be had an anti-drilling function.Can rotate with key with the movable convex cover that connects of door, have the anti-drilling sheet effect concurrently.

Secondly, tapered end self-protection.At the tapered end front end, there are one or more tapered end circles to connect, or are fixedly connected with the tapered end that anti-drilling headkerchief and/or anti-drilling sheet are housed with one or more anti-drilling headkerchieves and/or the combination of one or more anti-drilling sheet; Perhaps, anti-drilling headkerchief the interior hypotenuse that connects with tapered end is arranged fasten breach or spinning limit or helicitic texture or external diameter greater than sleeve diameter or internal diameter less than the tapered end external diameter or with tapered end between filler is arranged or has movable with it anti-drilling sheet and the tapered end that connects and be fixedly connected; Perhaps, the anti-drilling sheet or the anti-drilling headkerchief of band draw bail connect with tapered end separately; Perhaps, tapered end circle, anti-drilling headkerchief, anti-drilling sheet alone or in combination, with the tapered end bushing pipe, sheath protects frame and connects.

The tapered end circle can be flat sheet type, cup type, dish-type, ring-like, can be made up of two parts or many parts; Anti-drilling headkerchief can be flat sheet type, cup type, dish-type, can be made up of two parts or many parts; Anti-drilling sheet can be a glass type, screw bolt-type, to tearing " U " font that forms open, can form by two parts or many parts; Anti-drilling sheet, anti-drilling headkerchief and tapered end circle all can have higher hardness, possess anti-drilling function (heat treatment HRC35-55).

The 3rd, tapered end connects firm.The tapered end bushing pipe that can be " several ", " U " font, on draw bail can be arranged, one connects with tapered end and/or tapered end circle and/or anti-drilling headkerchief, other end and lock housing lid are fixedly connected; Perhaps, one of tapered end bushing pipe replaces the tapered end sleeve directly to connect with the tapered end inner body, and other end and lock housing lid are fixedly connected; Perhaps, be connected with sheath on the door, protect frame or their similar device.

The tapered end lining pipe side of being, tubular type, sealing cast; Sheath can the side of being, tubular type; Protect frame and can be " several ", " U " font, the sheath of band closed head or tapered end lining pipe are with beyond the panel that stretches out door; Sheath, protect frame and all can have anti-drilling performance.

The architectural feature that above-mentioned three aspects have been arranged, a kind of high-insurance security door and corresponding lock thereof just have been born, and it comprises whole features of aforementioned three aspects.It not only is used for the present invention, also can be widely used in the security door and the lock of the vehicles such as car, ship or objects such as strongbox, cabinet.

Compared with the prior art the present invention has following beneficial effect.

1. lock is positioned at after the panel of door, and under the protection of the panel of door, its exposed parts seldom even does not expose fully.Prior art tapered end end face exposes, and each position of tapered end end face all can be encroached on, and bores, prizes, pounds, beats all very convenient.The present invention hides the hole that is locked on the door can have only the key piece cross-sectional sizes, makes means of destruction, and tool used in crime all is very limited, and almost can't set about at the various destructions of lock.Can't resemble and dial tapered end being drawn from door the prior art, how because do not reach tapered end, to draw? tapered end leaves the panel certain distance, and the front has anti-drilling sheet to stop, makes to draw to dial also quite difficulty.On the door convex cover is arranged, add tapered end and vertically install, just extremely difficult especially.

2. the present invention's tapered end circle has increased function, has enlarged the scope of application, and not only the anti-drilling function of tool also can be fixedly connected with tapered end, becomes the strength member of protection tapered end.Can do not removed from tapered end, make the tapered end expose portion become the stress point of infringement action as prior art.Tapered end circle, anti-drilling headkerchief and anti-drilling sheet be the anti-drilling function of tool all, before the three firmly is connected in tapered end, has protected tapered end effectively.Even panel is torn, but also self-defense of tapered end.Anti-drilling sheet can be with panel, anti-drilling headkerchief, tapered end bushing pipe and sheath, protect that frame is movable to be connected, and has enlarged the scope of application of anti-drilling sheet, is convenient to form the multilayer proofing device, more effective protection tapered end.Anti-drilling sheet connects earlier with anti-drilling headkerchief, and the method for after-baking can connect anti-drilling sheet with anti-drilling headkerchief is movable, has improved protection effect.

3. the tapered end bushing pipe is fixedly connected with tapered end and lock housing lid respectively, and connecting mode can connect by tapered end bushing pipe self structure, and is more solid and reliable than two screw attachment of prior art.The various abilities of dialling and shaking sled of drawing of resisting have been improved.

4. will hide firm three aspects that connect of lock, tapered end self-protection and tapered end in conjunction with utilization, solve the problem of security door tapered end security protection more all sidedly.Overcome and only solved tapered end self-protection problem on the one hand, the drawback of attending to one thing and lose sight of another in the prior art.Rethink destruction, by no means easy, make door lock, thereby also make security door reach the requirement of high insurance, meet or exceed the pertinent regulations standard.

5. simple in structure, be convenient to make, provide cost savings.As " several " font tapered end bushing pipe, not only effective with the tapered end bushing pipe of various draw bails than the bushing pipe connection of prior art, and also cost is low, has saved material, has simplified technology.Plain film formula tapered end circle had both been saved material for another example, had simplified technology, the more important thing is to be convenient to select for use suitable anti-drilling material." U " shape anti-drilling sheet has not only solved the activity articulation issues of anti-drilling sheet and anti-drilling headkerchief or door, and simple in structure, cost is lower.Anti-drilling headkerchief connects with tapered end, is difficult problem always, because of anti-drilling headkerchief behind Overheating Treatment and incrustation, the one, hardness is very high, is difficult for processing, the 2nd, destroy decorative layer easily.Mostly prior art is to use the pin joint method, is subjected to structural limitations, and pin can be very not thick, and such one is unreliable, and the 2nd, not attractive in appearance.Anti-drilling headkerchief attached method of the present invention, multiple structure, as the breach docking structure, over-surplus fit structure, interior hypotenuse structure etc., not only performance is good, and simple in structure, and cost is low.The tapered end bushing pipe replaces sleeve directly to become tapered end, connects more firmly, and cost is cheaper.

6. the various structures of the present invention not only can be used for the present invention, and can be used for other class locksets.As tapered end, also can be used for tapered end and be exposed to lock structure outside the panel with the self-protection device.For the door and the lock of other structures provides new technology.
