Abstract

The utility model relates to a lighter capable of preventing children from lighting, wherein, a grinding wheel is composed of an axle, a side wheel, and a middle wheel. The axle can support on a bracket in rotation. The side wheel and the middle wheel are arranged on the axle. The middle wheel contacts to a flint hole under the bracket below the middle wheel. The middle wheel and the axle are fixedly connected. A central circular hole is arranged on the side wheel. A plurality of arced slots which are parallel to an axle line are evenly distributed on a wall of the hole along the circumference. Arced teeth are evenly arranged on an axle corresponding to the arced slots along the circumference. When the lighter capable of preventing children from lighting is used, the rotation is even and smooth; when children play the lighter and use small finger force to rotate the side wheel, the utility model has good sliding effect, and the lighter capable of preventing children from lighting can effectively prevent the children from lighting.

Description

The lighter that a kind of children of preventing strike sparks

The utility model relates to a kind of lighter, the lighter that especially a kind of children of preventing strike sparks.

At present, along with popularizing that lighter uses, this instrument of getting fire easily is seen everywhere in people's life, as long as gently rotate its emery wheel with have gentle hands, presses the valve opening pressing plate simultaneously, just can make and light lighter.This lighter just exists very big dangerous hidden danger to the very strong children of curiosity.At an easy rate, if the lighter that does not just need great finger strength just can light allows child take and lights, breed disaster probably.The patent No. provides a technical scheme for 96215836.4 utility model, with system one polygonal hole on the cincture of lighter or the middle wheel, the cross section of the shape that system one is identical with the shape in described hole on its corresponding axle, the minimum diameter in hole greater than the corresponding section spool maximum gauge.Such structure make lighter when sparking cincture or middle wheel rotate not steadily, simultaneously, when children used, its sliding was bad, security is relatively poor.

The purpose of this utility model is to improve the deficiencies in the prior art, and a kind of rotation uniform and stable is provided, and good the prevented children of the sliding effect lighter of striking sparks.

For achieving the above object, the utility model is taked following design:

Lighter includes gas tank and top assembly and the support and the emery wheel that are fixed on the gas tank, emery wheel wherein is made up of axle, cincture and middle wheel, the rotatable twelve Earthly Branches of described axle are on support, cincture and middle wheel are located on the described axle, take turns in described on the flint hole under the described support that is against its below, described middle wheel connects firmly with described, establishes a center hole on the described cincture, circumference is evenly distributed with some deep-slotted chip breakers parallel with axis in described hole wall upper edge, and described deep-slotted chip breaker can be an arc groove.Corresponding with it axle upper edge circumference is shaped on the arc tooth equably, and described arc tooth also can be a circle-arc tooth.Difference 〉=the 0.1mm of maximum gauge of the axle of the minimum diameter in described hole and corresponding position, the number of described deep-slotted chip breaker can 3-8, and the number of teeth of the arc tooth on the axle is greater than the number of the deep-slotted chip breaker of correspondence, and generally the number of arc tooth is greater than 7.

In actual applications, system one on the cincture can be distributed with the circular hole of arc-shaped slot, be provided with described round-arced tooth on the described axle at corresponding cincture place, cincture can rotate on axle, and middle wheel then is fixed on the axle.

In use, if rotate described cincture gently with finger, because cincture dallies on axle, wheel rotates in can not driving, so can not make this lighter.If finger strength is enough big, the deep-slotted chip breaker effect that then makes the arc tooth on the axle place the cincture hole can make axle rotate, and wheel pivoting friction firestone is being made lighter in driving by axle.

The lighter that the utility model provides uses the rotation uniform and stable, and when children played, when promptly rotating its cincture with little finger strength, sliding effect was good, can prevent effectively that children from making lighter.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment:

Shown in Fig. 3,4, be shaped on a circular hole 2 at the center of cincture 1, evenly be distributed with 6 arc grooves 3 on the hole wall in circular hole.Shown in Fig. 5,6, cincture 1 join with it connection the axle 4 corresponding positions the axle periphery on be laid with 12 circle-arc teeth 5.The aperture of the minimum of cincture 1 is 0.2mm with the difference of the maximum gauge of the diameter of axle of the axle 4 that is provided with circle-arc tooth 5 places.

Shown in Fig. 5,6, middle wheel 6 is fixed on the axle 4, on the axle 4 of the both sides of middle wheel 6, be provided with cincture 1, be provided with axial positioning structure (this structure is expression on figure) in the outside of cincture 1.
