The specific embodiment
The controlling pull force of the improvement that this utility model provides and the thread-changing dental-floss device that can move forward, in the present embodiment, the making that all is formed in one of each assembly, its material all can be plastics except annular elastomer 15.
See also Fig. 1, this utility model dental-floss device comprises a lever body of rod 1 and a rotor 2.
See also Fig. 1 to Fig. 4, an end of the lever body of rod 1 forms bifurcated support arm 4, and the other end forms handle 8, and central part forms the flat hollow framework parallel with the lever body of rod 6.
Respectively there is an eyelet 3 at the tip of bifurcated support arm 4, and the bifurcated base portion forms a larger eyelet 5.These eyelets are guiding dental floss 24 use.
Vertical two sides of framework 6 respectively have the identical horizontal slotted eye 7 of a shape size, can vertically and only limit to vertically be free to slide between the arc front and rear edge at its two ends for rotor 2.
See also Fig. 5 and Fig. 6, rotor is for to be combined by a rotating shaft 9, two identical winding rolls 10, two identical annular elastomeric 15 pin buckles 16 identical with two.Two ends of rotating shaft 9 respectively form one group of clasp 17 than the arranged outside axial blind hole, and with one group of pin stake 18 of outermost, each can connect each end and winding roll 10 of padlock.
See also Fig. 7, pin stake 18 is extended with diameter and the rotating shaft one less than the described axial blind hole in rotating shaft for rotating shaft 9, form four race diameter protruding pins identical with rotating shaft 9 in the outermost end of stretching out axial blind hole and consist of spline 19, can with the interior mother rib lateral rotundum of winding roll 10 shown in Figure 8 in the corresponding combination of spline 21 that consists of of four grooves, make rotating shaft 9 and the circumferential padlock of winding roll 10, both must rotate together when rotating.
Please continue to consult Fig. 7, clasp 17 forms for the bulge loop 20 that is formed the quartering by the circular shell of quartering outer ring, can bend along modification reinstatement after pressure is removed during pressurized.Have the modification space between clasp 17 shell internal diameters and pin stake 18 small diameters, clasp 17 is in radially curved under changeable type during pressurized from outside to inside.
During an end when suit one winding roll 10 inboards in rotating shaft 9, first spline 21 is aimed at spline 19, exert pressure again and push winding roll 10, this moment, clasp 17 axial compressions changed radially pressurized into and curved under modification gradually along bulge loop 20 circular arc external forms, until bulge loop 20 embeds the rear reinstatement of annular groove 22 fully, reach axial padlock winding roll 10 in the purpose of an end of rotating shaft 9.
See also Fig. 5, Fig. 6 and Fig. 8, winding roll 10 forms the SANYE flap knob 11 that diameter is larger than the outside, is beneficial to the end user and is pinching rotary rotor with finger.Knob 11 leaf flap recess also can be beneficial to dental floss to be passed through.The outermost of winding roll 10 forms the sidewall 12 of a knob, and the sidewall appearance forms a plurality of radial fins 14.There is circular hole at the sidewall center, and circular hole has shoulder hole 23 than the depths, can for pin buckle 16 extruding one annular elastomeric 15 be glued with radial fin 14 knob sidewall 12 the surface and be fixedly installed in.
See also Fig. 6, pin buckle 16 main bodys are oval of two branches, and an end is that larger diameter circle cap is in order to suppress annular elastomeric 15; Other end outermost diameter is less inwardly cumulative, form the flange clasp greater than main body circle bar diameter, to change gradually axial compressive force after pressurized enters in knob sidewall 12 circular holes is radial pressure, can make two branch's main body circle inside modification of bar and restore to the original state when clasp passes through knob sidewall 12 interior shoulder hole 23, squeeze buckle lock ring shape elastomer 15 is in the outside of knob sidewall 12.
By above-mentioned pin buckle 16 extruding annular elastomeric 15, make annular elastomeric 15 apply pressure to knob sidewall 12 surfaces because of bounce pressure, and produce the larger elasticity crack of a friction between annular elastomeric 15 and knob sidewall 12 interfaces, and further increase friction by radial fin 14 increase friction areas and pressure, form a clamp bolt seam 13, for bolt folder dental floss end.
The circumference of knob sidewall 12 diminishes from inside to outside gradually, jointly forms the large inwardly crack of convergent of an opening with annular elastomeric 15 circular arc appearances, and it is clamping fixed that the end user can be easy to smoothly with bolt in dental floss end importing clamp bolt seam 13.
Being combined as in the slotted eye 7 that first rotating shaft 9 is placed in the lever body of rod 1 framework 6 of this utility model dental-floss device, rotating shaft 9 two ends stretch out outside framework 6, put respectively and block an interior mother rib lateral rotundum of winding roll 10, these two winding rolls, 10 outermost fixedly mount annular elastomeric 15 in upper with pin buckle 16 extruding respectively again, complete the combination of rotor 2, also complete the combination of this utility model dental-floss device.
