The specific embodiment
Embodiment 1
As Fig. 1, Fig. 3 and Fig. 4, first embodiment, one dental-floss device mainly comprises the lever body of rod 1, a ripping bar 2 and a rotor 3.The lever body of rod 1 at one end forms the support arm 16 of a pair of bifurcated, forms elongated hollow lever 11 at the other end, is supplying ripping bar 2 to be installed near triangular form pedestals of central cervical region 13 formation 14 and is becoming its fulcrum.An eyelet 161 is respectively opened at the tip of two bifurcated support arms 16, and the support arm base portion is then opened big eyelet 15.Hollow lever 11 is being opened a notch 12 towards the veutro of ripping bar 2, for the ripping bar body of rod 21 when depressing fully, can slightly increase the ripping bar body of rod 21 that extra work angle scope such as Fig. 4 dotted line represent '.
As Fig. 1, Fig. 3, shown in Figure 4 and see also shown in Figure 2ly in addition, ripping bar 2 comprises a ripping bar body of rod 21, padlock piece 22 and two linked blocks 23,24.The ripping bar body of rod 21 at one end bifurcated and holds padlock piece 22 and is placed in one so that be installed on the triangular form pedestal 14, and the bifurcated end points then forms camber pawl 215 again, as the usefulness of support rotor 3.Ripping bar fulcrum axis hole 212 can make the ripping bar body of rod 21 and triangular form pedestal 14 link via axis hole 141 for inserting for the tip 25.The padlock piece is stirred tip axis hole 213 and is inserted to stir padlock piece 22 for the tip 27.Linked block is pulled tip axis hole 214 and is inserted to pull linked block 23,24 for the tip 26.The non-proper circle of the shape of axis hole 214, but the slotted eye of a camber allow to postpone to start interlocking gear with an of short duration spinning movement.
It is that fulcrum rotates that padlock piece 22 inserts the tip 26 with its axis hole 224, and inserts axis hole 223 by the tip 27 and stir.One end of padlock piece 22 forms padlock pawl 225 and makes it and can't rotate in order to padlock rotor 3.
Linked block 23,24 is set to a pair of mainly providing by ripping bar body 21 and passes on the equilibrated strength of pulling to rotor 3.It is hinge that this two linked block inserts axis hole 232,242 with the tip 25, and inserts axis hole 234,244 by the tip 26 and pull it.Camber pawl 235,245 is for being used for pulling rotor 3, and with ripping bar body 21 on camber pawl 215 common support rotors 3 at fixed position internal rotation.
The central part circumferential surface of rotor block 31 forms a chain gear 37, and the gear both sides form two road matrix groove faces 38 and can be stretched into by camber pawl 235,245, and blocking rotor block 31 must not have axial moving; Two outside again sides of two road matrix groove faces have then respectively formed the winding roll 36 of a surface depression, and trend was overlapped when its surperficial depression can make dental floss roll be around in, and helped fastening of dental floss tail end.Rotor block 31 outermost two ends respectively have the knob 33 of a trilobal cross to move the line of growing permanent teeth for the user rotary rotor.The blade root portion groove of SANYE knob is dental floss is led to the clamp bolt by winding roll a passage.The clamp bolt then is made up of ring-like elastomer 32, Luo silk 35, pad 34.
The compound mode of rotor-ripping bar mechanism is: earlier padlock piece 22 is placed in the ripping bar body of rod 21 of bifurcated, align axis hole 213,223 backs and insert the tip 27; The rotor 3 that to install the clamp bolt more places on the camber pawl 215, then linked block 23,24 is placed on the rotor 3 and snaps in the matrix groove face 38 of rotor block with the camber pawl 235,245 of linked block; Align axis hole 214,224,234,244 backs and insert pin 26; Last with hot melt or gluing the two ends of the tip 26 are fixed among the axis hole 234,244 again.
Then rotor-ripping bar mechanism can be installed on the lever body of rod, behind the axis hole 141 on 212,232,242 pairs of triangular pedestals 14 of axis hole, insert the tip 25, reuse hot melt or gluing are fixed on the two ends of the tip 25 among the axis hole 232,242.
To shown in Figure 7, interlocking gear is made up of ripping bar body 21, padlock piece 22, linked block 23,24, the relevant tip 25,26,27 and epitrochanterian chain gear 37 as Fig. 5.The purpose that this interlocking gear is set particularly runs into the adjacent slot of tooth closely for when the dental floss tension imports slot with the action of saw thing, and available padlock rotor must not make it and rotated that to prevent that dental floss from producing on slot horizontal mobile.
After dental-floss device has been laid dental floss preparation use, when user is depressed ripping bar, ripping bar body 21 can be stirred padlock piece 22 earlier and make it the chain gear 37 of snapping, just pulls linked block 23,24 then and pull rotor 3 by linked block to make it to leave the lever body of rod and come tensioning dental floss.This be because of ripping bar when beginning to pull, being wound on epitrochanterian dental floss can hold rotor and make it to keep original position, thereby holding linked block 23,24 makes it keep original position, and axis hole 214 is a camber slotted eye, can not touch the tip 26 when initial, have only when edge is conflicted the tip 26 thereon, linked block 23,24 just can be pulled, thereby pulls rotor.This of short duration action postpones to allow ripping bar body 21 to pull padlock piece 22 with the tip 27 to stretch among the chain gear 37 for the padlock pawl 225 of naming a person for a particular job with the tip 26.Still it is noted that in this: the tip 27 is along with ripping bar body 21 is the fulcrum operation with the central point of the tip 25, and to pull padlock piece 22 be the fulcrum operation with the central point of the tip 26, for holding this two different operation camber line track, axis hole 223 also must not be proper circle, Yi Bian must dig the gap in response to it.
In addition, the ripping bar body can be pulled for 21 times and be propped up the lever body of rod, or push rotor 3 to the ripping bar body and finish and take off lock to hold ripping bar body 21 conversely for making rotor disengaging padlock.After rotor can rotate freely, user turning knob 33 in the desired direction moved the line of growing permanent teeth.
Fig. 8 extremely dental floss shown in Figure 11 can pass two bifurcated support arm tips, then dental floss two ends are crossed over the lever body of rod two sides from lower to upper through big eyelet respectively, two winding rolls lead respectively, be prepared for furling two circles of reeling on the winding roll of using dental floss, reel in the opposite direction on the winding roll of clean dental floss more than six circles being prepared for supplying with, again dental floss two tail ends are fastened respectively on two clamp bolts at last.If dental floss once uses 50 centimeters, then the dental floss tail end of supply side will be left about 20 centimeters.Exhausted dental floss and clean dental floss are separated mutually with specified path, though the two standoff distance is nearer when passing through big eyelet 15, also foot applies required sanitary condition.Dental floss is wound on two winding rolls with opposite direction, and when with knob during toward required direction rotary rotor, a winding roll can furl exhausted dental floss, and another winding roll then disengages clean dental floss.Must be frequent when using dental-floss device move the line of growing permanent teeth, change the back if remaining less than two circles of supply side moving for several times, or dental floss is too lax when surpassing ripping bar stay bolt scope, user can be taken off dental floss and reel more than six circles recovery operation more again from supply side.
The mode of dental floss of reeling in the opposite direction still can be when user be pulled ripping bar and is lifted rotor stay bolt dental floss, and the moment that dental floss is produced on two winding rolls is repealed by implication and allowed the unlikely rotation of rotor.Even if it is a lot of and make diameter that tangible difference be arranged that the dental floss roll pitch of the laps is counted difference on two winding rolls, the winding roll of the less number of turns can make two moments be able to balance with more strength stay bolt dental floss.
The formation of clamp bolt is the sidewall that is made it to prop up knob blade face wall projection 331 by Luo silk 35 through the ring-like elastomer 32 of pad 34 extruding.Dental floss can slip into by being fastened in ring-like elastomer 32 and the knob sidewall 331 formed cracks.Fig. 8 indicates symbol 32 ' the be represented by dotted lines profile of ring-like elastomer before not being squeezed, be squeezed after do a contrast.Elastomer can produce a constant resilient pressure and prop up the raised line surface of knob sidewall 331 after being squeezed, thereby forms a clamp bolt of holding dental floss with the friction folder.The appearance of half cone type knob sidewall adds the appearance of ring-like elastomer tubular type, can make therebetween the crack of slipping into of dental floss quickly and easily.
To shown in Figure 14, an existing ripping bar and a rotor of simplifying of simplifying with embodiment 2 usefulness one done explanation as Figure 12.Ripping bar 2 replaces with the second embodiment ripping bar 4 and rotor 5 with rotor 3 among the embodiment 1.The ripping bar lever arm 41 front end bifurcateds of ripping bar 4 respectively are provided with an axis hole 42 on divergent ends 43, divergent ends 43 terminations are installed with a drum type support chamber 44 and rotate freely on wherein with support rotor 5.
For making rotor 5 rotation installings and support on drum type support chamber 44, this rotor can be divided into two 1/2 rotors.Wherein left 1/2 rotor 51 has a socket 512 its outsides and is axle journal 511, and its inside is three dowels 513, and another 52 of right half way around has a connecting axle 522 and Yu Qiduan place to offer three locating slots 523.These two 1/2 rotors are inserted by two side shaft holders 441 of support chamber 44, and connecting axle 522 is further passed dividing wall 441 insert sockets 512 and locating slot 523 and dowel 513 are meshing with each other, be an assembly with a long Luo silk 55, pad 34, Luo medicated cap 56 and with respectively a ring-like elastomer 32 is affixed at two ends then.Axle journal 511 on 1/2 rotor 51 of a left side and the axle journal 521 on right 1/2 rotor 52 respectively place the bearing block 441 of both sides, support chamber, and the internal diameter of bearing block 441 is greater than the external diameter of axle journal 511 and 521, so that this two axle journal can respectively put an elastomer axle sleeve 53.When user imports dental floss in the slot with saw thing action, similar but replace the interlocking gear function of first embodiment, with the rotation of enough friction impedance rotors.The external diameter of elastomer axle sleeve 53 has a little gap for allowing it in bearing block, among no external force situation lower rotor part can rotate freely on support chamber 44, but when user levers up rotor stay bolt dental floss, the axle journal 511,521 of rotor can be pulled to and bear against elastomer axle sleeve 53 and prop up bearing block 441, elastomer axle sleeve 53 is filled up stressed side clearance to increase this side contacts area with distortion, and with the existing higher coefficient of friction of elastomer, will be according to required enhancing friction impedance rotor rotation, thereby the impedance dental floss is laterally mobile, particularly runs into closely adjacent tooth slot.The dental-floss device cleaning teeth space that is explained orally with this second embodiment, can omitting the rotor that move before the line of growing permanent teeth than the dental-floss device that first embodiment is explained orally, to take off lock-step rapid, and all the other operations then can be said so identical.
