Combined wheel and lighter using same

Technical Field

The invention relates to the field of lighters, in particular to a combined wheel and a lighter using the combined wheel.

Background

The existing lighter comprises a shell with a fuel cavity arranged inside and an ignition assembly for ignition, wherein the ignition assembly can adopt an electronic ignition mode or a grinding wheel ignition mode. The ignition assembly of current emery wheel mode of striking sparks includes rotatable combination wheel and with the flint that combination wheel cooperation friction struck sparks, the steel wheel and the coaxial limit wheel that sets up at the steel wheel both ends are seted up to the lateral wall including the lateral wall to the combination wheel, and when using, the user drives the steel wheel rotation through dialling the commentaries on classics limit wheel, and the steel wheel is scraped the flint through the edge and is produced the ignition and use the spark.

During production, the steel wheel is cylindric, and its both ends terminal surface is the planomum, the perforation that link up is seted up along its axial to the steel wheel, the limit wheel is equipped with the grafting post on towards the interior terminal surface of steel wheel, is equipped with the pivot on the outer terminal surface, and the limit wheel is planted the rigid coupling at the steel wheel both ends through the grafting post to make and change coaxial setting. The lighter is provided with a switching hole for the rotary connection of the combined wheel, so that the combined wheel can be conveniently and rotatably assembled on the lighter through a rotating shaft.

When the lighter is produced, the knife edge has a uniform direction, and only when the direction of the knife edge is consistent with the rotating direction of the combined wheel, the knife edge can generate sparks by scraping and rubbing the flint, so that the use stability of the lighter is ensured. However, in order to ensure the mounting posture accuracy of the combination wheel, the assembler needs to observe the direction of the knife edge in a direct-viewing manner, and since the knife edge is small in size, the error judgment probability is increased due to long-time direct-viewing observation of the eye pattern, the rework workload is increased, the assembly efficiency is reduced, the eye health is affected due to long-time direct-viewing observation of the assembler, and occupational diseases such as myopia are easily caused. Therefore, in order to improve the assembly efficiency and reduce the production cost, the combined wheel with the large shaft and the small shaft arranged at two ends is arranged on the market, the combined wheel can be assembled rapidly on a large scale in a turnover plate assembly mode, specifically, the two ends of the combined wheel form differentiated outlines by arranging the large shaft and the small shaft, the turnover plate is provided with a true embedding groove for the combined wheel to be embedded in a unique posture, during machining, the combined wheel is embedded in the embedding groove in a preset posture, and then the multiple combined wheels are assembled to the corresponding lighters in a unified mode through the turnover plate, so that large-scale assembly and machining are realized. Specifically, the combined wheel is embedded in the embedding groove from top to bottom in an axis horizontal mode, and two ends of the embedding groove are respectively provided with a groove cavity matched with the profiles of the large shaft and the small shaft, so that the combined wheel is embedded in a unique posture. However, this structure has the following drawbacks: 1. because the diameter difference between the large shaft and the small shaft is small, the contour difference between the large shaft and the small shaft is small, and after the flap is used for a long time, the groove cavity corresponding to the small shaft cannot be distinguished and prevents the large shaft from being inserted due to abrasion, so that the flap loses the function of distinguishing the direction of the combination wheel, the rejection rate is increased, and rework is needed; 2. because the profile difference of major axis and staff is less, the assembly quality can't be through the direct-view observation difference for assembly quality can't examine to the combination wheel of accomplishing to turn over the board embedding and correct, only can match the installation and produce mars steadily through observing and verify the judgement with the lighter, because can't verify the combination wheel installation gesture accuracy in the assembly process of the preceding stage, make the degree of difficulty of doing over again the dismouting increase, both reduced production efficiency, still lead to manufacturing cost and rejection rate to increase because of taking place the part damage easily when the dismouting returns.

In addition, when the diameter difference between the large shaft and the small shaft is large, the diameter of the small shaft is small, the structural strength of the small shaft is affected, and the use stability is affected due to the fact that the small shaft is easily broken due to the action of external force.
