The utility model content
The technical problems to be solved in the utility model is that a kind of keyhole protection device flexible and convenient to use will be provided.
The scheme that solves the problems of the technologies described above is: a kind of keyhole protection device; comprise housing, thread escutcheon and locking mechanism; thread escutcheon is installed on the housing; locking mechanism comprises self-locking magnetic tongue, tongue hole, lid key hole and the key of uncapping that matches with lid key hole; self-locking magnetic tongue and tongue hole are installed in respectively on housing and the thread escutcheon; lid key hole is installed on housing or the thread escutcheon; the self-locking magnetic tongue matches with the tongue hole; the key of uncapping comprises uncap key body and the lid key magnet of establishing thereon, and lid key magnet matches with the self-locking magnetic tongue.
Scheme to above-mentioned technical solution problem describes below:
Thread escutcheon is the part (or parts) that can cover and can decontrol keyhole.It has different planforms and motion mode, adopts diverse ways to be installed on the housing according to its different motion mode, just cooperates by axis hole when rotating as it to be installed on the housing.Locking mechanism is thread escutcheon can be locked in fastening position can decontrol its mechanism again.Housing is that protection lock eye-cap and locking mechanism are installed, and the part that can directly or indirectly be connected with lock.When keyhole protection device with the lock be connected after, thread escutcheon just can cover and decontrol keyhole.Housing can be special, and also door or the environment division installed of the part of the lock of protection or lock can be as housing as the handle shell of lock, door etc.Housing can be one, and also several sections is formed.
Self-locking magnetic tongue and tongue hole are installed in respectively on housing and the thread escutcheon and are meant, the tongue hole just was installed on the thread escutcheon when self-locking magnetic tongue was installed on the housing, and the self-locking magnetic tongue just was installed on the thread escutcheon when tongue hole was installed on the housing.The self-locking magnetic tongue is installed on housing or the thread escutcheon, can be directly to be installed on it, and also is installed on it indirectly by other part.It can be to install or be made on housing or the thread escutcheon directly, indirectly that the tongue hole is installed on housing or the thread escutcheon.It also can be to install or be made on housing or the thread escutcheon directly, indirectly that lid key hole is installed on housing or the thread escutcheon.
The self-locking magnetic tongue is to cooperate the part (or parts) that thread escutcheon can be locked in fastening position with the tongue hole.Because self-locking magnetic tongue and tongue hole are installed in respectively on housing and the thread escutcheon, so self-locking magnetic tongue and tongue hole cooperate can be locked in fastening position with thread escutcheon.It is exactly that the self-locking magnetic tongue injects in the tongue hole and thread escutcheon can be locked in fastening position that the self-locking magnetic tongue matches with the tongue hole, and the self-locking magnetic tongue withdraws from the tongue hole can decontrol thread escutcheon.The self-locking magnetic tongue is the part that will move, and in order to narrate conveniently, we cooperate the position that thread escutcheon can be locked in fastening position to be called the latched position of self-locking magnetic tongue on one side of range of movement the self-locking magnetic tongue with the tongue hole.We can not cooperate the pinning thread escutcheon to be called the release position of self-locking magnetic tongue in the position of fastening position with the tongue hole at the another side of range of movement the self-locking magnetic tongue.The self-locking magnetic tongue has the magnetic self-locking magnetic tongue of being made by magnet by magnet (permanent magnet) or part.The iron self-locking magnetic tongue of being made by ferromagnet by ferromagnet (ferromagnetic material is done adult) or part is arranged.Iron self-locking magnetic tongue is simple, but the safety difference is used less.The self-locking magnetic tongue is to have the self-lock force interaction energy to get back to the magnetic tongue of latched position automatically.With elastic component (as spring) elastic force is that the elastic force self-locking magnetic tongue of self-lock force is complicated, and to adopt a kind of be the gravity self-locking magnetic tongue of self-lock force with the own wt so also special here.The gravity self-locking magnetic tongue is simple and reliable for structure, is installed on the keyhole protection device that risers (as door) locks but only be suitable for protection, and for this reason, special again here, and to adopt a kind of be the magnetic self-locking magnetic tongue of self-lock force with magnetic force.The self-locking magnetic force of magnetic self-locking magnetic tongue is produced by the ferromagnet of self-locking magnetic tongue and adapted or magnet, and the ferromagnet of this adapted or magnet can be special-purpose also dual-purposes, and what adopted dual-purpose here just can make the magnetic self-locking magnetic tongue simpler than elastic force self-locking magnetic tongue.The planform of self-locking magnetic tongue and motion mode have multiple.The self-locking magnetic tongue is an integral body, also several assemblys.The self-locking magnetic tongue can moving linearly, also can rotate or other motion.Usually we make little axle shape (or substantially little axle shape) with the self-locking magnetic tongue, it are installed in allow it make axial linear movement in the duct.The tongue hole is to cooperate the structure that thread escutcheon can be locked in fastening position with the self-locking magnetic tongue, and it can be hole, groove, rank, breach etc.
Lid key hole is the place, location of key of uncapping, and it can be a hole, a recess, the face that sign is arranged, but how it is made a square hole.It is stifled that lid key hole and keyhole are not afraid of than the no moving parts in big and shallow inside, also draws out stifled thing easily even be blocked.Lid key hole generally with in the housing does not communicate.Lid key hole and self-locking magnetic tongue install back self-locking magnetic tongue near lid key hole, or thread escutcheon when closing the self-locking magnetic tongue near lid key hole.The self-locking magnetic tongue near lid key hole be the magnet body of the magnet of magnetic self-locking magnetic tongue or iron self-locking magnetic tongue near lid key hole, near and outside the hole.When the key of will uncapping injects when cover location, tegmentum key hole, key hole, its lid key magnet magnetic pole is just relative close every the ferromagnet of magnet magnetic pole that covers key hole shell and magnetic self-locking magnetic tongue or iron self-locking magnetic tongue, or thread escutcheon is close relatively when closing.Above-mentioned can have certain deviation relatively.Since the magnet magnetic pole of lid key magnet magnetic pole and magnetic self-locking magnetic tongue or the ferromagnet of iron self-locking magnetic tongue relative close they will pass through magnetic interaction.Lid key magnet and cooperating of self-locking magnetic tongue are exactly ferromagnetic cooperation of covering key magnet and the magnet or the iron self-locking magnetic tongue of magnetic self-locking magnetic tongue, be exactly that their self-lock forces that can overcome the self-locking magnetic tongue by magneticaction draw (or pushing away) to the release position from latched position the self-locking magnetic tongue their close (comprising when thread escutcheon is closed close relatively) the relatively when key of uncapping exactly injects and cover in the key hole.They produce and attract magnetic force when lid key magnet and iron self-locking magnetic tongue ferromagnet relative engagement.They also produce attraction magnetic force when lid key magnet and magnetic self-locking magnetic tongue magnet opposite pole relative engagement.They produce and repel magnetic force when lid key magnet and magnetic self-locking magnetic tongue magnet like pole relative engagement.Lid key magnet and magnetic self-locking magnetic tongue magnet like pole relative engagement can prevent that the burglar from covering release in the key hole with the iron plate insertion but magnet is had demagnetizing effect, so, here their opposite pole relative engagement that adopt when lid key magnet cooperates with magnetic self-locking magnetic tongue magnet more, the while we regulate the self-lock force of self-locking magnetic tongue and latched position to the distance of release position make iron plate in covering the key hole with the attraction of self-locking magnetic tongue is little can not release.The planform of key of uncapping has multiple, usually our the square sheet made with a nonferromagnetic material (or basic square sheet) is established (normally being packed with) thereon as the key body of uncapping and is covered key magnet, (establish and allow its two poles of the earth when covering key magnet outside the key body sheet of uncapping) done one again and worn annular distance and just make the key of uncapping.Certainly it will do to such an extent that just in time can cooperate with lid key hole.
Key eye protective device allows its thread escutcheon cover with lock and can decontrol keyhole when being connected.When keyhole protection device protection is installed in lock on the door, how is installed in and allows thread escutcheon cover on the door and can decontrol keyhole by housing.Our key of will uncapping injects and cover in the key hole when uncapping, and at this moment draws (or pushing away) to the release position from latched position the self-locking magnetic tongue by lid key magnet with just cooperating of self-locking magnetic tongue, and soon the self-locking magnetic tongue draws (or pushing away) to go out from the tongue hole.At this moment we push thread escutcheon aside with regard to available hand or the key of uncapping and expose keyhole.We inject in the keyhole with regard to available lock key and have unblanked like this.Close when cover, need only and shift thread escutcheon onto fastening position and extract the key of uncapping again out, the self-locking magnetic tongue is just got back to latched position and is entered in the tongue hole thread escutcheon is locked in fastening position under the self-lock force effect.
The utility model is compared with aforementioned prior art, and the self-locking magnetic tongue that is equivalent to pellet shot from a slingshot can directly pin thread escutcheon, and this just can save lock core makes more simple in structurely, and this has also saved switch cover those inflexible transmission links of when operation makes flexible and convenient to use.The utility model just provides a kind of keyhole protection device flexible and convenient to use like this.
For making the utility model improve the following optimization measure that remakes more:
1, it will be stuck in the self-locking magnetic tongue outside the tongue hole when key closed thread escutcheon again to have the extraction of a kind of tongue hole to uncap, and we claim that this tongue hole is block tongue tongue hole.Our key of will uncapping inserts cover and just the self-locking magnetic tongue can be drawn (or pushing away) to the release position in the key hole during for block tongue tongue hole operation, then thread escutcheon is closed, and then the extraction key self-locking magnetic tongue of uncapping just can enter the tongue hole thread escutcheon has been pinned.For making the pass thread escutcheon make things convenient for us outside block tongue tongue hole, to set into the hole deviation face, when closing thread escutcheon, just can not block like this, just needn't be again with having uncapped key, the self-locking magnetic tongue has pinned thread escutcheon through the tongue hole that the guiding of hand-hole inclined-plane just can enter oneself automatically.
2, we make a plurality of groups that (comprise two) more than two with the tongue hole and the lid key magnet of self-locking magnetic tongue and cooperation thereof, and this each group is called the locking group of locking mechanism.Locking mechanism had after a plurality of locking groups must each locking group the self-locking magnetic tongue all to withdraw from the tongue hole be release, thread escutcheon could be opened, this just can strengthen theftproof.We make a plurality of locking groups of locking mechanism all a plurality of locking groups of release of a magnet again.Magnet all a plurality of locking groups of release is that one two magnetic pole inserts towards opposite substantially magnet and covers a plurality of locking groups that can not make each locking organize all releases in the key hole.Such magnet inserts and covers in the key hole otherwise make each locking organize all releases, the self-locking magnetic tongue that locking group more than two must be arranged is a magnetic self-locking magnetic tongue, so, magnet all a plurality of locking groups of release just to comprise the self-locking magnetic tongue that plural locking group is arranged in a plurality of locking groups be magnetic self-locking magnetic tongue.Usually we with a magnet all the self-locking magnetic tongue of a plurality of locking groups of release all make magnetic self-locking magnetic tongue.Locking mechanism had a magnet all after a plurality of locking groups of release the burglar just can not thread escutcheon have been opened with the easiest above-mentioned magnet of making, this has just more improved theftproof.We make a plurality of locking groups of a plurality of keyhole protection device locking mechanisms all a plurality of locking groups of release of a different magnet again, and the key of uncapping of these a plurality of keyhole protection devices can not be opened mutually, have just further improved theftproof again.Lid key magnet cooperates with magnetic self-locking magnetic tongue, covers cooperating of key magnet and magnetic self-locking magnetic tongue magnet exactly.The like pole relative engagement mode that is combined with of this two magnet and opposite pole relative engagement mode.Two kinds of the arctic and arctic relative engagement mode and the South Pole and South Pole relative engagement modes are arranged again in the like pole relative engagement mode.Two kinds of the north and south magnetic pole relative engagement modes that the South Pole of the northern south magnetic pole relative engagement mode of covering the key magnet arctic and the self-locking magnetic tongue magnet South Pole and lid key magnet and the self-locking magnetic tongue magnet arctic are arranged in the opposite pole relative engagement mode.We organize two magnet magnetic pole relative engagement modes and just can make all a plurality of locking groups of release of a magnet by adjusting each locking.We again by adjust a magnet all a plurality of lockings of release organize the position of each locking group or two magnet magnetic pole relative engagement modes and just can make a plurality of keyhole protection device locking mechanisms all a plurality of locking groups of release of a different magnet are arranged.
3, we the lid key hole of a plurality of keyhole protection device locking mechanisms with uncap make on the key different cooperate concavo-convex just can bigger reduction with opening rate enhancing theftproof.Recessed is groove recess etc., and protruding is raised line projection etc.Cover on the key hole when recessed being made in, protruding just being made in uncapped on the key, when the recessed key epirelief of uncapping that is made in just is made in and covers on the key hole.We can not open with concavo-convex their key of uncapping that just can make of making different cooperations on the key of uncapping mutually in the lid key hole of a plurality of keyhole protection device locking mechanisms.It is different that to cooperate the concavo-convex shape that is meant them, size, position, quantity etc. that difference arranged be exactly difference.Because the lid key hole and the key of uncapping are all bigger, so we just can and uncap and make the concavo-convex of different cooperations on the key in the lid key hole of a plurality of keyhole protection device locking mechanisms of thousand ten thousand, this just can reduce greatly opens rate enhancing theftproof together.Illustrate a bit, do recessedly or protruding on the key uncapping, usually on the key body of uncapping, make recessed or protruding exactly.
4, the uncap lid key magnet of key and magnetic self-locking magnetic tongue magnet or the ferromagnetic relative engagement of iron self-locking magnetic tongue is the relative engagement that will cover key hole shell across a part, and we claim that it is a functional hole shell part this part lid key hole shell.Functional hole shell part must be made with nonferromagnetic material.We are called iron hole shell part with partly or entirely making with ferromagnetic material of non-functional hole shell part.There has been iron hole shell part burglar to sound out release in the key hole and uncapped with regard to being difficult to put into to cover with fritter magnet, this is just to inhale in the key hole on iron hole shell part because fritter magnet enters to cover, be not easy to move, also be not easy to lean out the position and the polarity of self-locking magnetic tongue, just be difficult to resolve lock and uncap, this has just strengthened theftproof performance.
5, for the lock key that we just will have magnet easy to use as uncapping key, its key body as the key body of uncapping, as covering key magnet, perhaps, is established its magnet loam cake key magnet with key the shank of the key sheet as the key body of uncapping and is made the key of uncapping.We just make key the shank of the key sheet the key body of uncapping that meets the key requirement of uncapping and establish (as being packed with) lid key magnet more thereon and just can make the key of uncapping when doing lock key.Allow when covering key magnet its two magnetic poles outside the key body sheet of uncapping establishing.Above-mentioned two kinds of keys of uncapping can both combine together with lock key well, and it is all very convenient to make key carry, uncap, unblank.In addition no matter be independent uncap key or with the uncap key of lock key as one, we will covers key magnet and cannot see outside being embedded on the key body of uncapping and just have more confidentiality and theftproof.
6, the eye-cap of unblanking certainly that (self-locking magnetic tongue withdraw from the tongue hole after) just can be opened automatically after we made release with thread escutcheon.Have under the deadweight effect from the gravity of opening from unblanking eye-cap from the eye-cap of unblanking; Certainly the elastic force of opening under the elastic force effect is arranged from unblanking eye-cap; Also has the magnetic force of opening certainly under the magneticaction from unblanking eye-cap.These several eye-caps of unblanking certainly can also be used in combination.There has been the eye-cap of unblanking the certainly key of uncapping to insert and cover in the key thread escutcheon and just opened automatically, made operation more flexible.We also can make thread escutcheon from closing thread escutcheon, particularly make under the deadweight effect simple and reliable for structure from closing thread escutcheon from the gravity that closes.Had and closed our back of unblanking of thread escutcheon certainly and extract the lock key thread escutcheon out and just can shut automatically, this also makes operation more flexible.Here explanation a bit will have the hand-hole inclined-plane to shut automatically if meet block tongue tongue hole.
The utility model keyhole protection device is simple in structure, reliable operation, take above-mentioned optimization measure after, more improved anti-blocking theftproof performance, more combine together with lock, use operation more flexible.It with lock just be used to the user provide need not two locks money but obtain the protection of two locks, but to be equivalent to two locks more convenient than two latching operations, particularly it also has the unexistent dustproof choke preventing function of lock.This is a kind of very practical keyhole protection device.

The specific embodiment
The keyhole protection device of embodiment 1 is shown in Fig. 1～5.Keyhole protection device comprises housing 1, thread escutcheon 2 and locking mechanism.Housing 1 is that a square mount structure is formed from steel substantially.Thread escutcheon 2 basic square bulks are made by nonferromagnetic material.Two ends, the left and right sides, thread escutcheon 2 lower end have that Fig. 3 dotted line represents about at the two-semiaxle of a straight line, this two-semiaxle is installed in respectively to seal in the groove of back, edge bottom, housing 1 left and right sides and by card article 3 and forms the hole, and thread escutcheon 2 just cooperates by axis hole and is installed on the housing 1 like this.Thereby thread escutcheon 2 two-semiaxles rotate flexibly at the Kong Zhongneng of housing 1 groove and card article 3 formation thread escutcheon 2 is rotated flexibly around its two-semiaxle.The position (position among the figure) that thread escutcheon 2 can be sealed the frame hole in its two-semiaxle forwards housing 1 frame to is exactly the fastening position of thread escutcheon 2.Thread escutcheon 2 also can produce outside the housing 1 frame hole lid is opened.
Locking mechanism comprises self-locking magnetic tongue 4, tongue hole 5, lid key hole 6 and the key 7 of uncapping that matches with lid key hole 6, and the key 7 of uncapping comprises uncap key body 8 and the lid key magnet of establishing thereon 9.This routine locking mechanism has three locking groups.
Do three last lower through-holes that mutually same row is equidistant in the tongue shell 10, these through hole lower end diameter diminish suddenly and become aperture.Self-locking magnetic tongue 4 is a shape, and its lower end diameter diminishes suddenly becomes little axle.Self-locking magnetic tongue 4 is made by magnet by magnet or little axle place, and its upper and lower side is a magnetic pole, so this self-locking magnetic tongue is a magnetic self-locking magnetic tongue 4.These three same self-locking magnetic tongues 4 (can only see the self-locking magnetic tongue 4 that is contained in tongue shell 10 interstitial holes among the figure) are installed in the middle and lower part, three holes of tongue shell 10 respectively, and the little axle in its lower end can pass outside the aperture of lower end, hole.Self-locking magnetic tongue 4 can move up and down in tongue shell 10 holes neatly.Three same springs 11 are installed in middle and upper part, 10 3 holes of tongue shell respectively, and it is the spring that self-lock force is provided for self-locking magnetic tongue 4, so this self-locking magnetic tongue 4 is again an elastic force self-locking magnetic tongue.Tongue shell 10 is installed on housing 1 top, and self-locking magnetic tongue 4 just is installed on the housing 1 indirectly by tongue shell 10 like this.Spring 11 upper ends withstand on the housing 1 below the edge, the lower end withstands on self-locking magnetic tongue 4 upper ends, self-locking magnetic tongue 4 a size rank are leaned against on the tongue shell 10 big aperture rank, at this moment the latched position (position among the figure) of little of the self-locking magnetic tongue 4 lower ends self-locking magnetic tongue 4 that just passes that Here it is outside tongue shell 10 holes.
Three tongue holes 5 (can only see the tongue hole 5 that is made in the middle of the back projection 12 among the figure) are made on the back projection 12 of thread escutcheon 2 upper ends corresponding with three self-locking magnetic tongues 4.When thread escutcheon 2 in fastening position, self-locking magnetic tongue 4 when latched position (i.e. position among the figure), the little axle in self-locking magnetic tongue 4 lower ends just in its corresponding tongue hole 5 with thread escutcheon 2 pinnings.This tongue hole 5 is block tongue tongue holes 5, so, on the projection 12 of back, be provided with hand-hole inclined-plane 14 outside the tongue hole 5.Lid key hole 6 also is made on the back projection 12 of thread escutcheon 2, and its upper wall is against each tongue hole 5, and self-locking magnetic tongue 4 lower end magnetic poles are just near lid key hole 6 when thread escutcheon 2 is closed.Lid key hole 6 is shallow and big square holes, but its lower wall has been done protruding (raised line) 15.Uncap key 7 and lock key 13 as one, the figure middle and upper part of lock key 13 handle sheets make can with the square block-shaped chip of lid key hole 6 couplings as uncapping key body 8, on this uncaps key body 8, be packed with three short cylindrical shapes corresponding and cover key magnet 9 and just make the key 7 of uncapping with self-locking magnetic tongue 4.Lid key magnet 9 at two magnetic poles on the key body 8 of uncapping outside the key body 8 of uncapping is unilateral.On the key body 8 of uncapping of this key 7 of uncapping, also do recessed (groove) 16 that matches with lid key hole protruding 15.Also has the individual annular distance 23 of wearing on the key.
Usual self-locking magnetic tongue 4 stops at latched position under spring 11 elastic force effects, little axle in self-locking magnetic tongue 4 lower ends and magnetic pole are just in the tongue hole 5 of correspondence when thread escutcheon 2 is closed.When key 7 reeves of uncapping were covered in the key hole 6, three lid key magnet 9 on the key 7 of uncapping were just relative close with self-locking magnetic tongue 4 magnet like poles in the tongue hole 5 every the hole shell, and their just repel mutually.Repel under the magneticaction at this, self-locking magnetic tongue 4 just moves to the release position from latched position, promptly withdraws from tongue hole 5, i.e. release.The result of Here it is lid key magnet 9 and 4 mating reactions of self-locking magnetic tongue.Just thread escutcheon 2 can have been opened after the release.The key 7 of uncapping leaves self-locking magnetic tongue 4, and self-locking magnetic tongue 4 just resets to latched position.Each self-locking magnetic tongue enters not only in separately the tongue hole 5 but also with thread escutcheon 2 through 14 guiding of hand-hole inclined-plane and pins when closing thread escutcheon 2.
This routine locking mechanism has three locking groups, and the self-locking magnetic tongue of three locking groups all is a magnetic self-locking magnetic tongue, and we can organize two magnet relative engagement modes by each locking and make three locking groups that a magnet can not release.The locking group lid key magnet that we will have adopts the South Pole and South Pole relative engagement mode with cooperating of self-locking magnetic tongue magnet, and the employing arctic that has and arctic relative engagement mode just can be made these three locking groups all three locking groups of release of a magnet.The burglar just can not unblank eye-cap with an aforesaid magnet.Even we do not change the position of each locking group, only change locking and organize two magnet magnetic pole relative engagement modes, (as original certain locking group is the arctic and arctic relative engagement mode, becomes the South Pole and South Pole relative engagement mode) can make all three locking groups of release of six kinds of different magnet.That is to say that we do six keyhole protection devices and can accomplish that their key of uncapping can not open mutually.We make different cooperate concavo-convex again on the lid key hole 6 of thousand ten thousand these routine keyhole protection devices and the key 7 of uncapping, the key 7 of uncapping of thousand ten thousand these routine keyhole protection devices can not be opened mutually, have just more strengthened theftproof.
Four screws 17 have been done in housing 1 frame back, just cooperate and can directly or indirectly keyhole protection device be connected with lock with screw and this screw.Thread escutcheon 2 is closed to cover keyhole, open and to expose keyhole.Keyhole protection device is connected afterwards tongue shell 10 and card article 3 and just compresses and be installed on the housing 1 with lock.When we protect door lock with this routine keyhole protection device, can allow it be connected by door, and forward be installed as shown in Figure 1 with lock.When we have the door lock of this routine keyhole protection device, the key 7 of uncapping on the lock key injected cover in the key hole 6, extract when uncapping key thread escutcheon 2 and just follow oneself and opened (this is outward-dipping because of thread escutcheon 2) with regard to release.Inject in the keyhole with regard to available lock key 13 then and unblanked.Shifting thread escutcheon 2 onto fastening position after lock and door are opened has pinned with regard to closing again.
This routine keyhole protection device can be effectively to locking dustproof anti-blocking and certain anti-theft feature being arranged.Because this routine thread escutcheon 2 can rotate flexibly, the switch cover operation does not have the intermediate transfer link again, and this thread escutcheon its is exactly that gravity is from uncapping, so this keyhole protection device is flexible and convenient to use when the protection door lock.
Locking mechanism comprises self-locking magnetic tongue 4, tongue hole 5, lid key hole 6 and the key 7 of uncapping that matches with lid key hole 6, the key 7 of uncapping comprises uncap key body 8 and the lid key magnet of establishing thereon 9, tongue hole 5 is made on the housing 1, and lid key hole 6 is made on the thread escutcheon 2, and self-locking magnetic tongue 4 is installed on the thread escutcheon 2.This routine locking mechanism has four locking groups.
Lid key hole 6 is made in the middle of the thread escutcheon 2, and it is a square hole, but left wall has been done protruding (raised line) 15.Lid key hole 6 is shallow and be not afraid of stifled greatly.6 both sides, thread escutcheon 2 loam cake key holes respectively do two vertical with lid key hole 6 near the identical circular holes of specification, four identical axle shape self-locking magnetic tongues 4 just are installed in these four holes respectively, thus self-locking magnetic tongue 4 just is installed on the thread escutcheon 2.Self-locking magnetic tongue 4 close lid key hole 6 those ends in the circular hole of thread escutcheon 2 are its heads, away from lid key hole 6 those ends are its afterbodys, it is subjected to circular hole constraint but can moves axially, and its tail end entered outward with regard to extensible this circular hole and is made on housing 1 frame in each self-corresponding tongue hole 5 when thread escutcheon 2 was closed.Self-locking magnetic tongue 4 main bodys are made by the ferromagnetic material steel, and its head is embedded with magnet 22, and the magnetic pole of magnet 22 is towards self-locking magnetic tongue 4 two ends end to end, so this self-locking magnetic tongue 4 is magnetic self-locking magnetic tongues.The position that self-locking magnetic tongue 4 tail ends enter tongue hole 5 is exactly its latched position, and it is exactly its release position that tail end withdraws from the position that tongue hole 5 heads head at the bottom of the circular hole of place.After self-locking magnetic tongue 4 main body steel are embedded in 22 magnetization of the interior magnet of head, the tail end of self-locking magnetic tongue 4 also has more weak magnetic, but the steel wall interaction energy in magnetic that this is more weak and tongue hole 5 is moved self-locking magnetic tongue 4 to latched position from the release position, even self-locking magnetic tongue tail end enters in the tongue hole 5, so this self-locking magnetic tongue 4 is magnetic self-locking magnetic tongues, so thread escutcheon 2 just enters in the tongue hole 5 at fastening position self-locking magnetic tongue 4 tail ends thread escutcheon 2 is locked in fastening position.Those following in four tongue holes 5 on housing 1 left and right side frame two tongue holes are block tongue tongue holes, therefore outside it, be provided with hand-hole inclined-plane 14, when 2 times fastening positions of thread escutcheon, hand-hole inclined-plane following two the self-locking magnetic tongues 4 of 14 guiding enter the tongue hole 5 of oneself, can not be stuck in the top tongue hole 5.
What Figure 10 drew is and the uncap key 7 of lock key 13 as one, and it is packed with as the key body 8 of uncapping with the nonferromagnetic material handle sheet of lock key 13, and four lid key magnet 9 corresponding with self-locking magnetic tongue 4 make.What Figure 11 drew is the independent key 7 of uncapping, and it is to be packed with four to make with self-locking magnetic tongue 4 corresponding lid key magnet 9 on the key body 8 of uncapping of nonferromagnetic material.Uncap separately only see on the key 7 two lid key magnet 9 be because lid key magnet 9 not embedding wear, two lid key magnet 9 just can be seen in the back in addition.Certainly lid key magnet 9 usefulness nonferrous materials be cannot see better outside sealing, and could improve confidentiality.Uncap separately to have done on the key 7 and wear annular distance 23, be through on the ring by it and lock key and use still easily, adopt certainly and use just more convenient as the key 7 of uncapping of one with lock key.All do on two kinds of keys 7 of uncapping with lid key hole 6 on protruding 15 recessed (grooves) 16 that match.Lid key magnet 9 magnetic poles on two kinds of keys 7 of uncapping are all outside the key body 8 of uncapping is unilateral.Two kinds of keys 7 of uncapping can both match with lid key hole 6 well.
The key 7 of uncapping inserts when covering in the key hole 6, it is just relative close every the hole shell with the magnet 22 of each self-corresponding self-locking magnetic tongue 4 head that each covers key magnet 9, they are that opposite pole is close relatively, they just attract each other, because lid key magnet 9 magnetic are strong, their the attraction just attraction than self-locking magnetic tongue 4 tail ends and tongue hole 5 iron walls is big, thereby moves self-locking magnetic tongue 4 to release position from latched position, be that self-locking magnetic tongue 4 tail ends withdraw from tongue hole, i.e. release.We just can up push away the key 7 of uncapping with thread escutcheon 2 after the release, directly shift onto and head on edge on the housing 1, the magnet 24 of thread escutcheon 2 upper end embeddings is at this moment just inhaled and on edge on the housing 1 thread escutcheon 2 is stopped at open mode surely, at this moment just can extract the key 7 of uncapping out, at this moment be inserted in the keyhole in the base plate circular hole 21 and unblanked with regard to available lock key 13.Close when cover us and just can shift thread escutcheon 2 pressures onto fastening position with pointing from the housing 1 edge nock 25.Thread escutcheon 2 is shifted after the fastening position each self-locking magnetic tongue 4 onto and is got back to latched position enter in the tongue hole 5 and again thread escutcheon 2 is pinned under the effect of magnetic self-lock force.
This routine keyhole protection device has four locking groups, and it is just more difficult that the key of not uncapping wants thread escutcheon is opened.The self-locking magnetic tongue of these four locking groups all is a magnetic self-locking magnetic tongue, and we can organize two magnet fit systems by locking these four locking groups are made all four locking groups of release of a magnet.Two locking groups to covering 6 left sides, key hole when us are made northern south magnetic pole relative engagement mode, two locking groups on the right are made north and south magnetic pole relative engagement mode, perhaps two of the left side locking groups are made north and south magnetic pole relative engagement mode, two locking groups on the right are made northern south magnetic pole relative engagement mode, and four such locking groups all are all four locking groups of release of a magnet.But, just become all four locking groups of release of a magnet as long as we change the two magnet fit systems (is that northern south magnetic pole relative engagement mode becomes north and south magnetic pole relative engagement mode as former certain locking group) of a locking group.This just can prevent that the burglar from having unblanked eye-cap with a piece magnet.We can make a plurality of keyhole protection device locking mechanisms all four locking groups of release of a different magnet, and the key of uncapping of these a plurality of keyhole protection devices can not be opened mutually, strengthens theftproof.We make different cooperate concavo-convex again on the lid key hole 6 of thousand ten thousand keyhole protection devices and the key 7 of uncapping, the key 7 of uncapping of thousand ten thousand keyhole protection devices can not be opened mutually, have just more strengthened theftproof.In addition, the burglar covers that release is impossible in the key hole 6 if want to insert with iron plate, this is because we are when manufacturing and designing, and just by regulating distance and the self-lock force of self-locking magnetic tongue 4 from the fastening position to the release position, makes the attraction of iron plate and self-locking magnetic tongue 4 can not release.
This routine keyhole protection device can be effectively dustproof to locking, anti-blocking as can be known from the above, and anti-theft feature is also better, uses flexible and convenient operation.
Locking mechanism comprises self-locking magnetic tongue 4, tongue hole 5, lid key hole 6 and the key 7 of uncapping that matches with lid key hole 6, and the key 7 of uncapping comprises uncap key body 8 and the lid key magnet of establishing thereon 9.This routine locking mechanism has only a locking group.Self-locking magnetic tongue 4 is installed on the housing 1 indirectly, and tongue hole 5 is made on the thread escutcheon, and lid key hole 6 is installed on the housing 1.
Self-locking magnetic tongue 4 be one upper coarse and lower fine, last short long concentric ladder cylinder down, it is made by the ferromagnetic material steel, it is an iron self-locking magnetic tongue 4 by gravity self-locking.Tongue shell 10 is made by nonferromagnetic material, it have one upper coarse and lower fine, last short long ladder circular concentric through hole down, self-locking magnetic tongue 4 just is installed in this hole just rightly.The dome 30 that nonferromagnetic material is made is embedded in the thick part of going up of tongue shell 10 ladder circular concentric through holes, just self-locking magnetic tongue 4 is encapsulated in the hole of tongue shell 10.Be welded with two rearward extending bolts 31 that dot on the housing 1, logical hole 32, two front and back is arranged on the tongue shell 10, this two hole 32 is enclosed within respectively on two bolts 31 and just tongue shell 10 is installed on the housing 1 with nut tightening, thereby self-locking magnetic tongue 4 just is installed on the housing 1 indirectly by tongue shell 10.Have above tongue shell 10 shoulder holes one with concordant horizontal planes 33 above the lid 30, also have left surface 34, back 35.After tongue shell 10 is installed on the housing 1, horizontal plane 33 is just concordant with 27 square subordinate limits, circle square hole on the housing 1, left surface 34 is just concordant with the 27 square portion left sides, circle square hole, and three faces of the round like this 27 square portion left sides, square hole and above-mentioned tongue shell 10 just formation cover key hole 6, covers key hole 6 like this and has been made on the housing 1 with regard to dress.These lid 6 the right, key hole are not sealed, and it can lead to round square hole 27 circle portions.

Locking mechanism comprises self-locking magnetic tongue 4, tongue hole 5, lid key hole 6 and the key 7 of uncapping that matches with lid key hole 6, and the key 7 of uncapping comprises uncap key body 8 and the lid key magnet of establishing thereon 9.Self-locking magnetic tongue 4 is installed on the housing 1 indirectly, and tongue hole 5 is made on the thread escutcheon, and lid key hole 6 is installed on the housing 1.This routine locking mechanism has five locking groups.
Five self-locking magnetic tongues 4 are by main body and be embedded in main body internal magnet 22 and make, and its magnetic pole is towards self-locking magnetic tongue two ends.Self-locking magnetic tongue 4 main bodys can also can be made by nonferromagnetic material by ferromagnetic material.Whole self-locking magnetic tongue 4 is the upper coarse and lower fine weak point long ladder concentric cylinders down of going up.Tongue shell 10 is made by nonferromagnetic material, is the square bulk substantially, and the arc end is arranged down.Do five through holes arranging like that just like lid key magnet 9 in the tongue shell 10, these five through holes are the up big and down small short long ladder concentric circles through holes down of, and five self-locking magnetic tongues 4 are installed in respectively in these five holes with regard to just right ground.Five the self-locking magnetic tongues 4 and the hole of being installed except that the short slightly point of middle that group all the other four groups identical.Figure 16 can only see the hole that install the self-locking magnetic tongue 4 corresponding with that lid key magnet of lower left 9 and it.
Hole shell 44 is made by nonferromagnetic material, and its upper end has been done and covered key hole 6.The hole shell is to embed the iron hole shell part 45 that iron plate is made on the lid key hole 6.Also do on this iron hole shell part 45 two with the key body 8 of uncapping on two recessed two protruding (raised lines) 15 that match.Lid key hole 6 is a rectangular opening except that two protruding (raised lines) 15, and it can cooperate with the key 7 of uncapping suitably, it is big and shallow be not afraid of stifled.Be that a π shape is recessed substantially below the lid key hole 6 of hole shell 44, its both sides also have little recessed, tongue shell 10 just be installed in this π shape recessed in, the small tappet of its both sides the recessed both sides of π shape little recessed in.Tongue shell 10 is installed in that the front is concordant on the hole shell 44.Housing 1 front do one with lid key hole 6 shapes identical through hole, also be welded with two rearward extending bolts 31 that dot, front and back through hole 32 on 44 liang of ears of hole shell is enclosed within respectively on two bolts 31 and just hole shell 44 and tongue shell 10 is installed on the housing 1 with nut tightening, self-locking magnetic tongue 4 just is installed on the housing 1 by tongue shell 10 and hole shell 44, and lid key hole 6 also is installed on the housing 1 with hole shell 44.Hole shell 44 is installed on the housing 1 hole identical with it, housing 1 front of just in time aliging, the lid key hole 6 of back on it, and this hole also becomes a part of covering key hole 6.The center line of circular shaft 29, circular hole 43, tongue shell 10 and hole shell 44 is all on the center line (face) of housing 1.
Five the tongue holes 5 corresponding with five self-locking magnetic tongues 4 are made in above the thread escutcheon 2 arc limits 40, and front-seat two tongue holes 5 and two tongue holes of row, back are actual to be a rank, and the left side, outside, tongue hole on front and rear row the right also is provided with hand-hole inclined-plane 14, and middle tongue hole is only a hole.Self-locking magnetic tongue 4 moves up and down at the Kong Zhongneng of tongue shell 10, and when they the time just can move downward under the deadweight effect in the upper end, hole, they all are that gravity self-locking magnetic tongue 4 also all is a magnetic self-locking magnetic tongue 4.The position that the rank of self-locking magnetic tongue 4 lean against on the rank, tongue shell 10 hole is exactly the latched position of self-locking magnetic tongue 4.Self-locking magnetic tongue 4 its lower end when latched position passes outside the hole, if at this moment thread escutcheon just enters in its lower end of fastening position in the tongue hole 5 thread escutcheon 2 pinnings.What Figure 16 was represented is exactly the situation that the self-locking magnetic tongue is locked in thread escutcheon 2 in latched position fastening position.Uncapping, it is just relative close every hole shell opposite pole with each self-locking magnetic tongue 4 magnet 22 respectively to cover key magnet 9 when key 7 reeves are covered in the key hole 6, they just attract each other by magnetic force, each self-locking magnetic tongue 4 just withstands on latched position moves upward to it and covers below the 6 times hole shells in key hole under the attraction magneticaction, the release position of Here it is self-locking magnetic tongue, at this moment each self-locking magnetic tongue 4 lower ends release with regard to withdrawing from tongue hole 5, at this moment thread escutcheon 2 just forwards open position clockwise under the deadweight effect, at this moment just exposes keyhole 36 in the circular hole 43 of housing 1.Thread escutcheon 2 is opened the back, and we will uncap till key 7 extracts when covering key hole 6 each self-locking magnetic tongue 4 out and just move downward its lower end rest above 40 left parts of thread escutcheon 2 arc limits under the deadweight effect.Thread escutcheon 2 is opened the back, and we have unblanked with regard to available lock key 13 insertion keyholes 36.
This routine keyhole protection device locking mechanism has five locking groups, and its theftproof is good.The self-locking magnetic tongue of these five locking groups all is a magnetic self-locking magnetic tongue, so we can organize two magnet fit systems by each locking these five locking groups are made all five locking groups of release of a magnet.We are when each locking group lid key magnet 9 and the cooperation of self-locking magnetic tongue 4 magnet, the employing north and south magnetic pole relative engagement mode that has, the employing north south magnetic pole relative engagement mode that has, just these five locking groups are made all five locking groups of release of a magnet, the burglar just can not unblank eye-cap with a magnet.Even do not change the position of each locking group, only changing each locking organizes two magnet fit systems (as original certain locking group is north and south magnetic pole relative engagement mode, becomes northern south magnetic pole relative engagement mode) and can make all five locking groups of release of 30 kinds of different magnet.We do 30 keyhole protection devices in other words, can accomplish that their key of uncapping can not be opened mutually, and this just can strengthen theftproof.Make the concavo-convex of different cooperations again on thousand ten thousand keyhole protection devices lid key holes 6 and the key 7 of uncapping, this just makes the key 7 of uncapping of ten million keyhole protection device not open mutually, has just more strengthened theftproof.
This routine keyhole protection device can be effectively dustproof to locking, anti-blocking and good theftproof performance is arranged.As long as will just open automatically as the key 7 mortise lock eye-cap 2 in the lid key hole 6 of uncapping of one with lock key when uncapping, extract the just available lock key 13 of the key 7 of uncapping then out and inject in the keyholes 36 and unblanked.Close when covering as long as pushing block 47 has up been pinned thread escutcheon 2 passes once pushing up with finger.So this routine keyhole protection device uses very flexible.
The keyhole protection device of embodiment 5 is shown in Figure 20～26.Embodiment 5 keyhole protection devices comprise housing 1, thread escutcheon 2 and locking mechanism.Housing 1 hot investment casting is made.Semiaxis at a straight line is arranged about thread escutcheon 2 lower ends, its right axle shaft 49 is contained in the circular hole of housing 1 right lower quadrant half slot and the formation of fixture block 50 right-hand member half slots, its left half axle is also installed in the same way, so just thread escutcheon 2 is cooperated by axis hole to be installed on the housing 1.Thread escutcheon 2 can rotate flexibly around its two-semiaxle, and changeing when sealing housing 1 lower frame hole when its is exactly its fastening position, and thread escutcheon 2 is just in fastening position among the figure.Housing 1 back has four screws 17 directly or indirectly to realize being connected with lock by it.When it with the lock be connected after keyhole just in housing 1 lower frame hole, can be covered and decontrol by thread escutcheon 2.We design two kinds of eye-caps of unblanking certainly for selecting for use this routine keyhole protection device.A kind of is that as shown in figure 21 magnetic force is from the eye-cap 2 of unblanking.Be embedded with magnet 51 on fixture block 50, thread escutcheon 2 bottoms are embedded with magnet 52, and this two magnet like pole repelled relatively mutually when thread escutcheon 2 was closed.This repels magneticaction on thread escutcheon 2, just can open automatically after making thread escutcheon 2 releases, but this magnetic force is little, thread escutcheon 2 was just opened under the deadweight effect fully after as long as it pushed thread escutcheon 2 to outer incline, so this thread escutcheon 2 also can be said so magnetic gravitation from unblanking eye-cap 2.Another kind is that elastic force shown in Figure 22 is from unblanking eye-cap 2.On fixture block 50, done concentric step round tube hole, concentric step cylinder push shaft 53 has been housed in this through hole right part, spring 54 has been housed in the left part.Keyhole protection device is connected rear spring 54 1 ends with lock and heads on the keyhole protection device installation place, and the other end heads on push shaft 53.When thread escutcheon 2 was closed, spring 54 elastic force acted on thread escutcheon 2 bottoms by push shaft 53 little axle heads.Thread escutcheon 2 is just opened under the elastic force effect automatically after the release, and this elastic force is also little, it if with thread escutcheon 2 be pushed into outward-dipping after, thread escutcheon 2 is just opened under the deadweight effect fully, so, can say that also this thread escutcheon 2 is oneself eye-caps 2 of unblanking of elastic force gravity.
Locking mechanism comprises self-locking magnetic tongue 4, tongue hole 5, lid key hole 6 and the key 7 of uncapping that matches with lid key hole 6, and the key 7 of uncapping comprises uncap key body 8 and the lid key magnet of establishing thereon 9.Self-locking magnetic tongue 4 is installed on the housing 1 indirectly, and tongue hole 5 is made on the thread escutcheon 2, and lid key hole 6 is installed on the housing 1.This routine locking mechanism has three locking groups.
Self-locking magnetic tongue 4 among the structure of three self-locking magnetic tongues 4, shape and material and the embodiment 4 is identical, also is embedded with magnet in its upper end, and they also are magnetic self-locking magnetic tongues 4, also are the gravity self-locking magnetic tongues.Tongue shell 10 is made by nonferromagnetic material, and it is such that key magnet 9 is for example covered in row of being in it, and planform is as three holes of embodiment 4, and three self-locking magnetic tongues 4 just are installed in these three holes respectively.Hole shell 44 is made by nonferromagnetic material, has done on it and has covered key hole 6.The last hole shell in lid key hole 6 is to embed the iron hole shell part 45 that iron plate is made, and also does protruding (raised line) 15 that matches with key 7 fovea superiors 16 of uncapping on this iron hole shell part 45.The cross sectional shape in lid key hole 6 is identical with key 7 cross sectional shapes of uncapping, and they can cooperate well.Tongue shell 10 cards are installed in the recurve of hole shell 44, and hole shell 44 is installed in the upper ledge of housing 1, and self-locking magnetic tongue 4 just is installed on the housing 1 by tongue shell 10 and hole shell 44 like this, and lid key hole 6 also is installed on the housing 1 by hole shell 44.
Three tongue holes 5 corresponding with self-locking magnetic tongue 4 are made in behind thread escutcheon 2 upper ends on the projection 12, and they all are block tongue tongue holes, have done hand-hole inclined-plane 14 on their back projection 12.Three self-locking magnetic tongues 4 can both move up and down in the hole of tongue shell 10 flexibly, and the position that it stops under action of gravity in the drawings is exactly its latched position.Just stretch out outside tongue shell 10 holes self-locking magnetic tongue 4 its lower end when latched position, if at this moment thread escutcheon 2 is when fastening position, pin thread escutcheon 2 with regard to entering respectively in the tongue hole separately their lower end.What see among Figure 21 is the situation of in the tongue hole 5 thread escutcheon 2 being pinned in the middle of middle that self-locking magnetic tongue 4 injects.
The key 7 of uncapping inserts to cover and respectively covers key magnet 9 in the key hole 6 just self-locking magnetic tongue 4 magnet opposite poles are relative close respectively with separately every the hole shell, they just attract each other by magneticaction, under this attracted magneticaction, self-locking magnetic tongue 4 just withstood on the release position of covering below 6 shells of key hole on latched position moves upward to it separately.When self-locking magnetic tongue 4 arrives the release position, the release of its lower end with regard to withdrawing from tongue hole 5.Thread escutcheon 2 has just been opened automatically after the release.Thread escutcheon 2 is opened the back, and we just can extract out in the keyhole that key 7 usefulness lock keys 13 insertions of uncapping expose and have unblanked.Each self-locking magnetic tongue 4 was got back to latched position when key 7 was uncapped in extraction under deadweight, but at this moment thread escutcheon 2 has been opened and it can not have been pinned.Close when cover as long as we shift thread escutcheon 2 onto fastening position each self-locking magnetic tongue 4 and just under hand-hole inclined-plane 14 guides, enter in separately the tongue hole 5 thread escutcheon 2 pinnings.
This example also can resemble embodiment 4 key 7 of uncapping of making a plurality of keyhole protection devices described and can not open mutually; also the reason iron plate inserts that cover in the key hole 6 can not release as described above, and lid key hole 6 also is provided with iron hole shell part 45 and can disturbs the burglar with fritter magnet exploration release.This routine keyhole protection device can be effectively dustproof to locking, anti-blocking and theftproof performance is preferably arranged, and uses flexible and convenient operation, also thread escutcheon 2 can be made handle especially and use.
Above we have enumerated five embodiment, but the utility model this and more.The keyhole protection device of embodiment 1～2 can be used to protect door lock, also can be used for protecting being installed in the lock that uses on the miscellaneous equipment.The keyhole protection device of embodiment 3～5 is mainly used in the protection door lock, the lock that also available its protection equipment that is installed on is erect and do not used on the risers of malleable upright state.
