Abstract
The utility model discloses an abrasive wheel group structure for a lighter, which is composed of two side wheels 20 positioned on both sides of an abrasive wheel 10 and two middle wheels 30 clamped between the side wheels 20 and an abrasive wheel frame 7. The outside diameter surface of the abrasive wheel 10 is provided with rolling stripes 11 with high a friction coefficient, and the inner parts of the end surfaces on both sides are provided with shaft seats 12. The inner circles of the annular side wheels 20 are provided with conical holes 21; the embedded ends 31 of the middle wheels 30 are fixed in the shaft seats 12; the conical ends 32 and the conical holes 21 are matched with each other in a loosening way; shaft ends 33 are positioned on the abrasive wheel frame 7. In the utility model, the side wheels 20 drive the abrasive wheel 10 to rotate and rub a flint 6 to produce sparks, and young children with small strength can not rotate the abrasive wheel 10, so the utility model is safe.
Description
The utility model relates to a kind of lighter emery wheel group structure.
Daily employed lighter, its emery wheel contact with firestone well, and the easy turn of emery wheel makes firestone splash spark.If do not noted, lighter falls into children's hand and plays the utmost point possibility of bringing out fire is arranged.
The purpose of this utility model is to provide a kind of lighter emery wheel group structure, to overcome above-mentioned deficiency.
The technical solution of the utility model is:
The outer diametric plane of emery wheel 10 is the concavo-convex roller line 11 of high coefficient of friction, is provided with the axle bed 12 of fixing middle wheel 30 in the end face of both sides; Two ring-type cinctures 20 place emery wheel 10 both sides, and its inner ring is provided with taper hole 21, and taper hole 21 than the major diameter limit laterally during installation; Wheel 30 is provided with built-in end 31, tapering end 32 and axle head 33 successively by erection sequence in two, built-in end 31 is inserted in the axle bed 12 fixing, 21 one-tenth loose fits of tapering end 32 and taper hole, axle head 33 places on the wheel stand, and wheel 30 is clamped in the wheel stand 7.
The axial line of emery wheel 10, cincture 20, middle wheel 30 becomes same straight line, and the external diameter of emery wheel 10 is less than the external diameter of cincture 20.
The rotation friction of emery wheel 10 of the present utility model and firestone 6 is to keep to the side to take turns 20 drive, and children are difficult for turn emery wheel 10 and rotate, thereby have played the safety precaution effect.
Fig. 1 is the utility model embodiment 1 main body schematic diagram;
Fig. 2 is the utility model embodiment 1 main cutaway view;
Fig. 3 implements side 2 main cutaway views for the utility model;
Fig. 4 is the utility model embodiment 3 main cutaway views;
Fig. 5 is the utility model embodiment 4 main cutaway views.
Now in conjunction with the accompanying drawings 1 to 5 and embodiment be further described below:
Embodiment 1: by shown in Figure 2 emery wheel 10, cincture 20 and middle wheel 30 are assembled on the wheel stand 7.When finger presses emery wheel group is rotated, the original parallel angle of cincture 20 deflections of the left and right sides makes cincture 20 sides 23 clamp emery wheel 10 end faces 14, and the tapering end 32 of adding taper hole 21 and middle wheel 30 takes turns 30 in rubbing and driving, thereby emery wheel 10 is rotated, friction firestone 6 percussion sparks.When if children use, because finger pressure is little, can't makes cincture 20 produce skew and clamp emery wheel 10 end faces 14, taper hole 21 can not produce effectively friction with middle wheel 30, and cincture 20 only dallies, and can not drive emery wheel 10 and rotate the firestone 6 percussion sparks that rub.
Following examples modes that wheel 30 rotates in cincture 20 drives and embodiment 1 were different, all the other all were same as embodiment 1.The mode that wheel 30 rotated during cincture 20 drove is respectively:
Embodiment 2: make step 24 in the cincture 20,30 on middle wheel is formed on the step 34 that step 24 matches, and step 24 is loose fit with step 34;
Embodiment 3: middle wheel 30 is made wheel track 35, is connected across on the rail chair 25 of cincture 20;
Embodiment 4: emery wheel 10 both ends of the surface 14 are shaped on the circular groove 15 of depression, and the protruding ring piece 26 that matches with circular groove 15 is established in cincture 20 sides 23.
Claims (2)
1, a kind of lighter emery wheel group structure, by two cinctures (20) that place emery wheel (10) both sides and be clamped in wheel stand (7) and cincture (20) between two wheels (30) form, it is characterized in that: the outer diametric plane of emery wheel (10) is the concavo-convex roller line (11) of high coefficient of friction, is provided with the axle bed (12) of fixing middle wheel (30) in the end face of both sides; Ring-type cincture (20) places emery wheel (10) both sides, and its inner ring is provided with taper hole (21), and taper hole during installation (21) than the major diameter limit laterally; Wheel (30) is provided with built-in end (31), tapering end (32) and axle head (33) successively by erection sequence in two, built-in end (31) is fixed in the axle bed (12), tapering end (32) becomes loose fit with taper hole (21), axle head (33) places on the wheel stand (7), thereby emery wheel (10), cincture (20) and middle wheel (30) are clamped between the wheel stand (7).
2, lighter emery wheel group structure according to claim 1, it is characterized in that: the axial line of emery wheel (10), cincture (20), middle wheel (30) becomes same straight line, and the external diameter of emery wheel (10) is less than the external diameter of cincture (20).
