Its vestibule of the lock core hole of tapered end is narrow and small relatively, and when checking blade groove, not only measurer discrepancy inconvenience also is difficult to the applying situation that arrives measurer amount face and workpiece soon, to its observation inconvenience.
The tip of Arc-key is placed in the middle, if stir because of foreign matter behind the tapered end locking or reason such as vibrations makes the blade internal orifice cross the lock core axis, when inserting Arc-key again, need rock Arc-key, inserts while shaking and could insert, and the flexibility ratio when this makes insertion is affected.
In addition, only frictionally generation interlocking motion between the blade makes whole blades be pulled out to the probability of tapered end enable possition big comparatively speaking simultaneously by foreign matter; Tapered end blade groove rear end is the go side, and this stays the space to disclosing backward to unplug to lock along blade groove with foreign matters such as steel wires, and this all influences secrecy.
The present invention is directed to the above-mentioned problems in the prior art, a kind of Arc-key tapered end is provided, its main purpose is: rotate a circle by Arc-key drive lock core and just can extract, be in correct fastening position when making the Arc-key tapered end extract key, thereby improve the secrecy of Arc-key tapered end.
A further object of the invention is the problem that solves tapered end blade groove observation inconvenience.
The objective of the invention is by providing a kind of Arc-key tapered end to realize with following structure, it comprises Arc-key, lock core, tapered end and the blade that has internal orifice, several blades are parallel in the blade groove of lock core, lock core is positioned at the lock core hole of tapered end, when the both sides of blade head faces the blade groove of tapered end, blade can follow moving radially of lock core along the blade groove of lock core, the middle part of Arc-key can be followed moving axially of lock core along the internal orifice of blade, the circumferential position of tapered end radial section blade groove is eccentric the setting with respect to lock core hole, and eccentric throw is slightly larger than lock core and the lock core hole radial clearance adds the blade groove width of blade and lock core to the gap sum.
As another embodiment of the present invention, the both sides of blade can have a wing, and a wing is with respect to the excircle eccentricity setting of lock core, and eccentric throw and eccentric direction are identical with the respective leaves film trap of tapered end.
As a kind of improvement of the present invention, have on the tapered end and give drilling, give middle cover is housed in the drilling, in put lock core hole and identical lock core hole and the blade groove of blade groove that has with described tapered end, the outer surface of this blade groove and middle cover connects, and lock core is arranged in the lock core hole of cover.
As a further improvement on the present invention, the summit of Arc-key tip can be arranged in relative Arc-key center line limit far away one side.
Further improve as of the present invention, blade has the side mouth, and elasticity thing together is housed in the side mouth.
The present invention also has a kind of improvement, and tapered end blade groove rear end is cecum.
Adopt said structure, because when insertion Arc-key drive lock core is near the tapered end fastening position rotates to 180 °, the outside steric hindrance retaining of tapered end blade groove lateral margin or lock core hole slot blade follows lock core motion radially, Arc-key can not be extracted by leaf baffle, only rotate a circle, Arc-key just can be extracted when dead bolt reached lock-out state, there be not mark, not remembering lock core corner and light all can make the Arc-key tapered end be in correct fastening position when bad, thereby improve the secrecy of Arc-key tapered end, middle cover can give first making outside tapered end, the cover blade groove was not subjected to the lock core hole restriction and can be convenient to observation with soon to the applying situation of measurer amount face and workpiece during measurer was come in and gone out.When the blade internal orifice ran off the lock core axis, still in facing toward the scope of blade internal orifice, Arc-key did not rock and can insert smoothly on the summit of Arc-key tip, had improved the flexibility ratio when inserting.The elasticity chain motion of thing reinforced blade together, making whole blades is cecum by probability reduction and the tapered end blade groove rear end that foreign matter is allocated to the tapered end enable possition simultaneously, shutoff foreign matter disclose the space that unplugs lock backward along blade groove, all strengthened the secrecy of Arc-key tapered end of the present invention.

Shown in Figure 36 is its tapered end and lock core radial section assembling schematic diagram.Have blade groove 5 on lock core hole 22 walls of its tapered end 3,5 two of blade grooves are a pair of, symmetrical, not eccentric mutually, lock core 2 has the blade groove 5 corresponding blade grooves 17 with tapered end 3, several blades 4 that have internal orifice 20 are parallel in the blade groove 17 of lock core 2, and lock core 2 is positioned at the lock core hole 22 of tapered end 3.The Arc-key tapered end is at the fastening position place, and promptly the both sides head 24 of blade 4 faces the blade groove 5 of tapered end 3.At this moment plug Arc-key 1, blade 4 can follow moving radially of lock core 2 along the blade groove 17 of lock core 2, and the middle part 6 of Arc-key 1 can be followed moving axially of lock core 2 along the internal orifice of blade 4; When driving lock core 2 Rotate 180s ° with Arc-key 1, Arc-key 1 can be extracted.Though at this moment the dead bolt (not shown) is stretched out, extension elongation is not necessarily enough, and dead bolt does not reach lock-out state as yet, and this moment, Arc-key 1 can be extracted, and caused the fastening position mistake easily as preceding having stated.
In the present invention, as shown in Figure 2, the wide of blade 4 and blade groove 5 is shown vertically among the figure, the dark of the length of blade 4 and blade groove 5 laterally is shown, Fig. 1 and Figure 12 vertically illustrate the length of blade groove 5.The circumferential position of tapered end 3 radial section blade grooves 5 is eccentric settings with respect to lock core hole 22, and blade groove 5 center lines are parallel with the horizontal center line of lock core hole 22.It is wide to the gap sum with the blade groove 17 that lock core hole 22 radial clearances add blade 4 and lock core 2 that its eccentric throw is slightly larger than lock core 2.Figure 14 laterally illustrates blade groove 17 wide of lock core 2.Observed its eccentric throw and suited for 0.2 millimeter to 2 millimeters greater than above-mentioned gap sum, under the enough condition of lock core hole 22 diameters, can be big 3 millimeters or more than.The shape of blade groove 5 on tapered end 3 radial sections can be buttress shape or arcuation, also can be arciform; Front end and rear end can be the go side, also can be cecum, and processing is convenient in the go side, and cecum is beneficial to tamper-proof, and visual applicable situation is decided.The profile of tapered end 3 can depend on the needs, and column only is shown in the accompanying drawing; Lock core hole 22 can be concentric with tapered end 3, also can be eccentric, only illustrates concentric in the accompanying drawing.Lock core 2 has the blade groove 5 corresponding blade grooves 17 with tapered end 3, and promptly lock core 2 radial section blade grooves 17 are eccentric settings with respect to the outer fenestra of lock core 2, and its eccentric direction is identical with the blade groove 5 of tapered end 3 at tapered end fastening position place with eccentric throw.As shown in figure 16, the front end of lock core 2 leaves key mouth 18, and as Fig. 1, Figure 14 and shown in Figure 15, the rear end of lock core 2 is left spoon and passed mouth 8.Spoon passes mouthfuls 8 and is the passage shape, and the tip 9 of section shape and Arc-key 1 is corresponding, is matched in clearance with the tip 9 of Arc-key 1, and its tip 9 can pass mouth 8 along spoon and follow lock core 2 and move axially during plug Arc-key 1.That can avoid like this that the tip 9 of Arc-key 1 produces the out-of-size scopes follows lock core 2 play radially.As shown in figure 31, blade 4 is the frame shape, has internal orifice 20, and for ease of punching press, blade 4 also can be improved to the doorframe shape of making as shown in figure 37 that does not have door.As depicted in figs. 1 and 2,6 at the middle part of internal orifice 20 and Arc-key 1 is and is slidingly matched.Illustrated in figures 1 and 2 is tapered end place in the closed position, then is in closed condition in extracting Arc-key 1 tapered end herein.Other structure of Arc-key tapered end and assembling are identical with aforementioned documents.
When inserting Arc-key 1 and drive lock core 2 from the tapered end fastening position Rotate 180 ° left and right sides, as shown in figure 10, blade groove 17 eccentric directions of lock core 2 are opposite with leaf groove 5 eccentric directions of tapered end 3, each part of the both sides head 24 of blade 4 is stopped by the position beyond blade groove 5 sides of tapered end 3 or the blade groove 5 respectively, can not insert blade groove 5, be that blade 4 can not follow lock core 2 slip radially, the middle part 6 of Arc-key 1 is stopped that by blade 4 Arc-key 1 can not be extracted.Above-mentioned when rotating to 360 °, blade groove 17 eccentric directions of lock core 2 just restore to the original state, and Arc-key 1 just can be extracted, and this moment, dead bolt (not shown) extension elongation was enough, and the correct fastening position of tapered end is guaranteed thus.Mark, lock core corner and light quality all seem inessential.
Another embodiment of the present invention such as Fig. 3, Fig. 4, Fig. 5 and shown in Figure 32, blade 4 are different from outside first embodiment, other structure of Arc-key tapered end, and assembling and use are identical.The both sides of blade 4 have a wing 10, and a wing 10 is with respect to the excircle eccentricity setting of lock core 2, and eccentric throw and eccentric direction are identical with the respective leaves film trap 5 of tapered end 3.Lock core 2 radial section blade grooves 17 can occupy the center with respect to the cylindrical of lock core 2, also eccentric setting (not shown eccentric setting of section).The blade groove 5 of vertical bubble head wing 10 and tapered end 3 is wide among the figure, and laterally the blade groove 5 of the length of the bubble head wing 10 and tapered end 3 is dark.When tapered end was in the closed position, a wing 10 was slidingly matched to being with blade groove 5 positions of tapered end 3 are corresponding, wide, and the length of a wing 10 is slightly larger than the dark of blade groove 5.When Arc-key 1 plug, a wing 10 stretches into or withdraws from the blade groove 5 of tapered end 3, blocks or discharge the rotation of lock core 2.With first embodiment in like manner, when inserting Arc-key 1 and driving lock core 2 from the tapered end fastening position Rotate 180 ° left and right sides, each part of two wing 10 of blade 4 is stopped by the part beyond blade groove 5 sides of tapered end 3 or the blade groove 5 respectively, can not insert blade groove 5, Arc-key 1 can not be extracted, and Arc-key 1 just can be extracted when only rotating to 360 °.Wherein Fig. 4 blade 4 shown in Figure 5 leaves two and has respective number blade groove 5 with the higher authorities' wing 10, tapered end 3, and the moment of torsion that a wing 10 can bear when this was under the closed condition with foreign matter rotational lock core 2 at tapered end strengthens, and strengthens the tapered end reliability.Tapered end 3 shown in Figure 5 has the blade groove 5 of a side and a wing 10 to be one, and it comes down to, and two blade grooves 5 interpenetrate, the two stature wings, 10 mutual fusions present, and with aforementioned its off-centre not contradiction are set.The width of each stature wing 10 and corresponding blade groove 5 thereof or eccentric throw be difference to some extent, in order to avoid can borrow groove extract Arc-key 1 when lock core 2 Rotate 180s °.
As a kind of improvement of the present invention, as Figure 27 and shown in Figure 28, have on the tapered end 3 and give drilling 19, give drilling 19 and can be positioned at the center with respect to tapered end 3, also can be partial to a certain side.Give be equipped with between the cylindrical of drilling 19 and lock core 2 in cover 12, other structure of Arc-key tapered end is identical.To shown in Figure 26, middle cover 12 has the lock core hole 22 of tapered end 3 in shape, position and size and aforementioned two embodiments and leaf groove 5 identical lock core hole 14 and blade groove 13, the lock core hole 22 and the blade groove 5 of replacement tapered end 3 as Figure 17 to Figure 20 and Figure 23.Blade groove 13 connects with the outer surface of middle cover 12, and an end is cecum or two ends all are cecum.In the giving the drilling diameter and can be interference or interference fits of cover 12 outside diameter and tapered end 3, lock core hole 14 diameters match with lock core 2 outside diameters.As Fig. 8 and shown in Figure 9, what middle cover 12 was packed tapered end 3 into gives drilling 19, and available pin 23, screw or spot welding (not shown) are fixed together.As shown in Figure 6 and Figure 7, lock core 2 is arranged in the lock core hole 14 of cover 12.The radial section shape of giving drilling 19 also can adopt shapes such as ellipticity and quadrangle or polygon, get final product suitable with it of middle cover outer surface of making except that the diagram circle.With aforementioned two embodiments in like manner, have only lock core 2 to rotate a circle, Arc-key 1 just can be extracted.When Figure 11 illustrates lock core 2 from tapered end fastening position Rotate 180 °, the situation that a wing 10 is blocked.Because giving in tapered end 3 outsides, makes earlier and its blade groove 13 and middle cover 12 outer surfaces perforation by middle cover 12, when checking blade groove 13, not only the measurer easy access also can be used the applying situation that arrives measurer amount face and workpiece soon, positive heart groove is like this, and eccentric grove is all the more so.Certainly, also tapered end 3 can be disconnected vertically, be connected as one again behind the making blade groove 5.
As a further improvement on the present invention, as Figure 21 and shown in Figure 22, the summit of the tip 9 of Arc-key 1 is arranged in relative Arc-key 1 center line limit far away one side, among the figure Arc-key 1 center line below, promptly middle part 6 be closely middle limit apart from that nearer limit of center line, the another side at middle part 6 is middle limit far away, vertically shows the wide of Arc-key among the figure.Other structure of Arc-key tapered end is essentially identical.Variation along with the middle part 6 both sides line styles of Arc-key 1, the position of the internal orifice 20 of respective vanes 4 is close to a side head 24 or a wing 10 of blade 4 thereupon, and size of key is high more under the same lock core diameter prerequisite leans on closely more, this be configured in extract Arc-key 1 after, blade 4 can be stirred or reason such as vibrations slides to internal orifice 20 along the blade groove 17 of lock core 2 and runs off lock core 2 axis places because of foreign matter, when inserting Arc-key 1 again, consult shown in Figure 29, Arc-key 1 then certainly will will be rocked between two parties in 9 summits, tip of Arc-key 1, its tip 9 is swung along blade 4 length directions, allow the summit of tip 9 to last internal orifice 20, insert and to pass through while shaking, this is affected the insertion flexibility ratio of Arc-key 1, guarantees that with the way that reduces size of key flexibility ratio is passive.At this situation, consult shown in Figure 30, the summit of Arc-key 1 tip 9 is arranged in relative center line limit far away one side, ignoring each gap apart from the distance of center line is: the degree of depth more than or equal to limit homonymy blade groove 5 in far away deducts the absolute value of the nearest mid point on nearly middle limit to the difference of the distance of Arc-key 1 center line, be less than or equal near in the degree of depth of limit homonymy blade groove 5 deduct far away in the nearest mid point on limit to the absolute value of the difference of the distance of Arc-key 1 center line, and previous absolute value is greater than zero, less than a back absolute value.If adopted middle cover 12, above-mentioned blade groove 5 be the dark of blade groove 13 deeply.Two guide angle β d of the tip 9 of Arc-key 1 can equate, as shown in figure 21; Also can one greater than another, consult shown in Figure 22.Like this, when the internal orifice 20 of blade 4 ran off lock core 2 axis places, the summit of the tip 9 of Arc-key 1 was in the scope facing to internal orifice 20 all the time, neither influences size of key, needn't rock also and can insert smoothly when inserting Arc-key 1.The Arc-key tapered end of prior art also can adopt.
Further improve as of the present invention, as Fig. 3 to Fig. 5, Figure 31, Figure 32 and shown in Figure 37, blade 4 has side mouth 21, and elasticity thing 11 together is housed in the side mouth 21, and other structure of Arc-key tapered end is identical.Side mouth 21 is positioned near blade 4 and the limit that the blade groove 17 of lock core 2 matches, can be arcuation, circle or nick shaped on the positive apparent direction of blade 4, and elasticity together 11 of things leave movement clearance.Same elasticity is the identical blade 4 of thing adapted side mouth 21 shapes together.Elasticity thing 11 together can be that spring steel, alloyed copper or plastics are made cross section for circular, rectangle or square straight filiform, two blunt, also can be the helical spring that spring steel wire or alloyed copper filament winding become.As shown in figure 34, several side mouths 21 are common to constitute a cavity, and two of cavity is cut off by the blade 4 with side mouth 21 not, and elasticity thing 11 together is arranged in this cavity, and tapered end is in closed condition, and Arc-key 1 has been extracted, this moment elasticity together thing 11 be straight.When the internal orifice 20 that stretches into blade 4 through key mouth 18 with foreign matter is stirred blade 4, between blade 4, exist the friction, also flexible thing together 11 is cascaded blade 4 to interlock and moves, make foreign matter that whole blades 4 are allocated to two heads 24 simultaneously or two wing 10 is concordant with the cylindrical of lock core 2, be that the difficulty of tapered end open position strengthens, the probability that tapered end is pushed aside descends.And middle part 6 both sides driven vane, 4 elasticities of flexure of Arc-key 1 thing 11 together just places two heads 24 or two wing 10 of whole blades 4 simultaneously with the concordant place of the cylindrical of lock core 2, is the tapered end open position as shown in figure 33, thus rotational lock core 2.This improvement can be adopted with the Arc-key tapered end combination of prior art.
The present invention also has a kind of improvement, and as shown in figure 13, blade groove 5 rear ends of tapered end 3 are cecum, and other structure of Arc-key tapered end is identical.Make the rear end of blade groove 5 be cecum and can give for when die casting tapered end 3 blade groove 5 rear ends to leave sprue 16, methods such as also can be after tapered end 3 is made sprue 16 usefulness being welded, rivet or be spirally connected be fixedly linked in the rear end of blade groove 5.On tapered end 3 radial sections, sprue 16 is identical with blade groove 5 section shapes.On tapered end 3 axial sections, sprue 16 rear ends are concordant with tapered end 3 rear end faces, and the sprue front end can be consulted shown in Figure 1, are positioned at the rear of tapered end assembling rear blade 4, do not influence blade 4 motions and get final product.When disclosing backward when dialling along blade groove 5 with foreign matters such as steel wires, sprue 16 stops foreign matter, constitutes the defence line one, strengthens the secrecy of Arc-key tapered end of the present invention.
Other structure of each part of the present invention, the assembling of tapered end and use are all with prior art that documents is addressed.The present invention each to have the position of relative motion all should leave movement clearance be conspicuous.The present invention can use metal and alloy or plastics manufacturings such as iron and steel, zinc, aluminium, copper, chromium, nickel.In a word, under the prerequisite that does not break away from the principle of the invention, some modification that persons skilled in the art can be made or improvement all belong to protection scope of the present invention.
