Abstract
The utility model is a wheel shaft structure for rotary shaft type friction wheel lighter, which comprises a shaft, a spark-producing roller on the shaft and two shaft-side wheels which are beside the spark-producing roller. The outside diameters of the two shaft-side wheels are bigger than that of the spark-producing wheel. The two shaft-side wheels are respectively fixed at two end of the shaft. The utility model is characterized in that the spark-producing roller is equipped on the shaft to revolve. Because the utility model adopts the structure above, it needs a rather big downward revolving force on the two shaft-side wheels and on the spark-producing wheel to make the light make a fire. But for a child whose strength is small and harmony of action is bad, he/she always turns only the shaft-side wheels and finds it hard to turn the spark-producing roller to make a fire. Moreover, the utility model is an improvement of the combination of the original part without adding new structures or new part and the production cost is not raised under the proposition of the realization of safety requirements, so as to ensure the competitive power of the product in the market.
Description
Technical field
The utility model relates to a kind of lighter, particularly a kind of wheel shaft structure of rotary shaft friction wheel lighter.
Background technology
Traditional friction wheel lighter obtains the extensive approval in market with the reliable of its simple and practical structure and use, continuous aggravation and international safety requirements along with domestic and international lighter market competition, each manufacturer has also released the product after improving accordingly, wherein, Chinese patent CN1434249A discloses a kind of " lighter of anti-child's sparking is wiped wheel ", its project organization main points are that " outboard wheel and a nearside wheel are housed respectively in the breast wheel both sides; outboard wheel and nearside wheel are notconnect state when outboard wheel is not subjected to side direction external force, the opposite sides of two-wheeled is provided with the engaging structure that can make both be meshing with each other and rotate when outboard wheel is subjected to side direction external force." its objective is and prevent that child from striking sparks, improve security.No matter the wheeled lighter of well-known friction is market or in the international market at home, the advantage of its competition is mainly reflected in that it is simple in structure, manufacturing cost and price are lower, though and the structure after the above-mentioned improvement has realized the requirement of security, but also, influence its competitiveness in market because its complicated structure causes the rising of manufacturing cost.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of structure of both having signed an undertaking simple, can make the child be difficult to beat the wheel shaft structure of the rotary shaft friction wheel lighter that catches fire again.
The technical solution of the utility model is: a kind of wheel shaft structure of rotary shaft friction wheel lighter, comprise rotating shaft, be installed on the flint wheel in the rotating shaft and be positioned at the diaxon side wheel of flint wheel both sides, the external diameter of described diaxon side wheel is greater than the external diameter of flint wheel, described diaxon side wheel is fixed in the two ends of rotating shaft respectively, is characterized in that described flint wheel is rotating to be installed in the rotating shaft.
Catching fire for guaranteeing that the adult applies downwards to beat after certain dynamics, is matched in clearance between above-mentioned flint wheel and rotating shaft, and its gap can be controlled between 0.05～0.1mm usually.
The utility model is owing to adopted the rotating version that is installed in the rotating shaft of flint wheel, when sparking, needing simultaneously diaxon side wheel, flint wheel to be applied the bigger power that is rotated down can make lighter beat, and relative child, because the coherent harmony of less its action in addition of its dynamics is relatively poor, when sparking, the diaxon side wheel is rotated, and difficulty is rotated flint wheel, catches fire so be difficult to beat.In addition, the utility model is only improved on the fit structure of former part, and not relating to increases new structure and part, under the prerequisite of realization security requirement relatively, does not improve production cost, thereby has guaranteed the competitiveness in market.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation after the utility model assembling.
The specific embodiment
The utility model as shown in Figure 1 and Figure 2, a kind of wheel shaft structure of rotary shaft friction wheel lighter, comprise rotating shaft 1, be installed on the flint wheel 2 in the rotating shaft 1 and be positioned at the diaxon side wheel 3 of flint wheel 2 both sides, the external diameter of described diaxon side wheel 3 is greater than the external diameter of flint wheel 2, described diaxon side wheel 3 is fixed in the two ends of rotating shaft 1 respectively, is characterized in described flint wheel 2 rotating being installed in the rotating shaft 1.
1 matched in clearance that is of above-mentioned flint wheel 2 and rotating shaft.The gap that above-mentioned flint wheel 2 and rotating shaft are 1 is 0.05～0.1mm.Above-mentioned wherein side wheel 3 and rotating shaft 1 one-body molded making, another side wheel 3 is the other end that tight fit is assemblied in rotating shaft 1, also is provided with respectively the shaft shoulder 1a that plugs with head both sides support plate 4 at the two ends of rotating shaft 1.The external diameter of above-mentioned flint wheel 2 is than the little 0.6 ± 0.1mm of diaxon side wheel 3 external diameters.
