Description

本考案は、エア工具の付属品に関し、具体的には、スリーブ構造である。 The present invention relates to an accessory of an air tool, and specifically has a sleeve structure.

リムを自動車に取り付けたり、自動車から取り外したりする場合、一般的に、エア工具を動力源として使用し、対応するスリーブと突き合わせることにより、ナットを締め付けたり緩めたりする。 When attaching or removing a rim from an automobile, an air tool is typically used as a power source to tighten or loosen the nut by matching it with the corresponding sleeve.

しかしながら、通常、エア工具と突き合わせるスリーブは、変形を防止するために一定の剛性を有しなければならないため、いずれも金属で製造され、スリーブがナットを締め付けたり緩めたりする際に、又は作動前後の作業中に、スリーブがリムと衝突することが非常に発生しやすく、リムに傷をつける場合があり、この状況は、要求の高い車の所有者又はこのリム(アルミ合金リム)の価格が非常に高い車の所有者にとって、受け入れにくく、自動車の修理工場(タイヤショップ)と車の所有者との間のトラブルが多発する。 However, since the sleeves that are usually abutted against the air tool must have a certain degree of rigidity to prevent deformation, they are all made of metal and work when the sleeve tightens or loosens the nut. During front and back work, the sleeve is very likely to collide with the rim and can scratch the rim, a situation where demanding car owners or the price of this rim (aluminum alloy rim) It is unacceptable for car owners who are very expensive, and there are many troubles between the car repair shop (tire shop) and the car owner.

従って、ある自動車の修理工場(タイヤショップ)は、リムに傷をつけることを防止するように、他の柔らかいもの(例えば布地)でスリーブの外周を覆うが、使用上不便であるだけでなく、リムのスリーブが入り込む孔に入りにくく、それにより適用が難しい。従って、ある業者は、スリーブにブラスチックスリーブを嵌着する方式を開発したが、ブラスチックスリーブが薄すぎると保護の効果がなく、ブラスチックスリーブが厚すぎるとリムの孔に入り込むことができないだけでなく、逆にスリーブの元の外径を削減し、その全体の剛性が不十分になり、そして、ブラスチックスリーブはスリーブに嵌合接合する過程に強く面接触し、組み立てにくい。 Therefore, one car repair shop (tire shop) covers the outer circumference of the sleeve with another soft material (eg fabric) to prevent scratching the rim, which is not only inconvenient to use, but also It is difficult to get into the hole where the rim sleeve enters, which makes it difficult to apply. Therefore, one vendor has developed a method of fitting a plastic sleeve to the sleeve, but if the plastic sleeve is too thin, there is no protective effect, and if the plastic sleeve is too thick, it cannot enter the hole in the rim. On the contrary, the original outer diameter of the sleeve is reduced, its overall rigidity becomes insufficient, and the plastic sleeve is in strong surface contact during the process of fitting and joining to the sleeve, making it difficult to assemble.

これに鑑みて、従来技術におけるスリーブがリムに傷をつけやすく、スリーブに他のものを嵌着することにより使用が不便であり、保護性がよくなく、リムに入り込みにくく、全体の剛性が不十分になり、組み立てにくい等の周知の問題を解決する。そのため、本考案は、スリーブ構造を提供し、スリーブ本体、Oリング、及び炭素繊維管を備え、該スリーブ本体は、駆動部及び該駆動部と同軸に接続された作用部を有し、該駆動部の外径が該作用部の外径よりも大きく、該駆動部と該作用部の外周面との接合箇所に段差部が形成され、該駆動部の自由端面には、内部へ軸方向に駆動孔が凹設され、該作用部の自由端面には、内部へ軸方向に作用孔が凹設され、該作用部の外周面にはリング溝が周設され、該Oリングは該スリーブ本体のリング溝に嵌着され、該炭素繊維管は、該スリーブ本体の作用部の外周面に嵌着され、その一端が該段差部に当接し、内周面が該Oリングに当接し、それにより、リムに損傷を与えることを回避し、使用の利便性を高め、保護を強化し、既存のリムに適用し、全体の剛性を維持し、容易に組み立てることができるという効果を達成する。 In view of this, the sleeve in the prior art is prone to scratching the rim, is inconvenient to use by fitting something else to the sleeve, is not well protected, is difficult to get into the rim, and has poor overall rigidity. It will be sufficient and solve well-known problems such as difficulty in assembling. Therefore, the present invention provides a sleeve structure, including a sleeve body, an O-ring, and a carbon fiber tube, the sleeve body having a drive unit and an action unit coaxially connected to the drive unit, and the drive unit. The outer diameter of the portion is larger than the outer diameter of the working portion, a step portion is formed at the joint between the driving portion and the outer peripheral surface of the acting portion, and the free end surface of the driving portion is inward in the axial direction. A drive hole is recessed, a working hole is recessed inward in the free end surface of the working part, a ring groove is provided around the outer peripheral surface of the working part, and the O-ring is the sleeve main body. The carbon fiber tube is fitted into the ring groove of the sleeve body, the carbon fiber tube is fitted to the outer peripheral surface of the working portion of the sleeve body, one end thereof abuts the step portion, and the inner peripheral surface abuts the O-ring. This avoids damaging the rim, enhances convenience of use, enhances protection, applies to existing rims, maintains overall rigidity and achieves the effect of being easy to assemble.

審査官が本考案の特徴及び特点をより良好に理解して認めることができるために、以下、実施例を挙げて図面を参照しながら説明する。 In order for the examiner to better understand and recognize the features and features of the present invention, examples will be described below with reference to the drawings.

図1〜図3に示すように、本考案の好ましい実施例に係るスリーブ構造100は、主にスリーブ本体10、Oリング20、及び炭素繊維管30を備える。 As shown in FIGS. 1 to 3, the sleeve structure 100 according to the preferred embodiment of the present invention mainly includes a sleeve body 10, an O-ring 20, and a carbon fiber tube 30.

図1〜図3を参照し、該スリーブ本体10は、一体に製造された円筒状の筒体である。該スリーブ本体10は、駆動部11及び該駆動部11と同軸に一体に接続された作用部12を有し、且つ該駆動部11の外径が該作用部12の外径よりも大きいので、該駆動部11と該作用部12の外周面との接合箇所には段差部13が形成され、該駆動部11の自由端面には、軸心位置から内部へ軸方向に駆動孔111が凹んで延設され、本実施例において該駆動孔111は四角孔であり、該駆動部11の外周面には、径方向に円の中心を貫通する位置決め孔112が形成され、該作用部12の自由端面には、軸心位置から内部へ軸方向に作用孔121が凹んで延設され、本実施例において該作用孔121は六角孔であり、該作用部12の外周面にはリング溝122が周設される。 With reference to FIGS. 1 to 3, the sleeve body 10 is a cylindrical cylinder manufactured integrally. Since the sleeve body 10 has a drive unit 11 and an action unit 12 coaxially and integrally connected to the drive unit 11, and the outer diameter of the drive unit 11 is larger than the outer diameter of the action unit 12. A step portion 13 is formed at a joint portion between the drive portion 11 and the outer peripheral surface of the action portion 12, and a drive hole 111 is recessed in the free end surface of the drive portion 11 in the axial direction from the axial center position. The drive hole 111 is a square hole in the extension, and a positioning hole 112 that penetrates the center of the circle in the radial direction is formed on the outer peripheral surface of the drive unit 11, and the action unit 12 is free. An action hole 121 is recessed and extended in the axial direction from the axial center position on the end surface, the action hole 121 is a hexagonal hole in this embodiment, and a ring groove 122 is formed on the outer peripheral surface of the action portion 12. It will be installed around.

図1〜図3に示すように、該Oリング20は、ゴム又は他の弾性材料で一体に製造された円形リング体である。該Oリング20は、該スリーブ本体10のリング溝122に嵌着され、該リング溝122から僅かに部分的に突出している。 As shown in FIGS. 1 to 3, the O-ring 20 is a circular ring body integrally manufactured of rubber or other elastic material. The O-ring 20 is fitted in the ring groove 122 of the sleeve body 10 and slightly partially protrudes from the ring groove 122.

図1〜図3を参照して、該炭素繊維管30は、炭素繊維で製造された軸方向の中空管体である。該炭素繊維管30は、該スリーブ本体10の作用部12の外周面に嵌着され、その一端が該段差部13に当接し、内周面が該Oリング20に当接し、該炭素繊維管30の外周面と該駆動部11の外周面とを面一にするが、該炭素繊維管30の内周面と該作用部12の外周面との間に隙間がある。該炭素繊維管30の管壁の厚さは0.3mm〜0.8mmの間である。 With reference to FIGS. 1 to 3, the carbon fiber tube 30 is an axially hollow tube made of carbon fiber. The carbon fiber tube 30 is fitted to the outer peripheral surface of the working portion 12 of the sleeve body 10, one end thereof abuts on the step portion 13, and the inner peripheral surface abuts on the O-ring 20. The outer peripheral surface of the driving unit 11 and the outer peripheral surface of the driving unit 11 are flush with each other, but there is a gap between the inner peripheral surface of the carbon fiber tube 30 and the outer peripheral surface of the working portion 12. The thickness of the tube wall of the carbon fiber tube 30 is between 0.3 mm and 0.8 mm.

従って、上記の内容は、本考案の好ましい実施例に係るスリーブ構造100の各部材及びその組合せ方式の説明であり、次に、その使用の効果を以下のように説明する。 Therefore, the above content is a description of each member of the sleeve structure 100 and a combination method thereof according to a preferred embodiment of the present invention, and then the effect of its use will be described as follows.

先ず、炭素繊維管30は、極めて薄い管壁を製造することができ、且つ管壁が極めて薄い状態で一定の硬度を有する(その硬度は依然として金属の硬度よりも低い)。従って、管壁が極めて薄い炭素繊維管30が該スリーブ本体10に嵌着された後、その全体の外径はあまり大きくすることなく、既存のリムに適用でき、全体の外径があまり大きくすることなく、スリーブ本体10の元の外径を減らす必要がなく、全体の剛性を保持でき、且つ炭素繊維管30自体の硬度は、耐摩耗効果を増加させ、耐用年数を増加させることができ、それにより、本考案は、リムに損傷を与えることを回避することができるだけでなく、使用が便利であり、保護性に優れ、既存のリムに適用でき、且つ全体の剛性を維持できる等の効果を有する。 First, the carbon fiber tube 30 can produce an extremely thin tube wall and has a certain hardness in a state where the tube wall is extremely thin (the hardness is still lower than the hardness of the metal). Therefore, after the carbon fiber tube 30 having an extremely thin tube wall is fitted to the sleeve body 10, it can be applied to an existing rim without increasing the overall outer diameter so much, and the overall outer diameter becomes too large. Without having to reduce the original outer diameter of the sleeve body 10, the overall rigidity can be maintained, and the hardness of the carbon fiber tube 30 itself can increase the wear resistance effect and increase the service life. As a result, the present invention not only avoids damage to the rim, but also has effects such as convenience in use, excellent protection, applicability to existing rims, and maintenance of overall rigidity. Has.

次に、該炭素繊維管30は、該スリーブ本体10に嵌着されるとき、スリーブ本体10と向かい合って接触せず、Oリング20とのみ接触する。従って、組み立てやすい効果を達成できるだけでなく、炭素繊維管30とOリング20等の消耗品を容易に交換することができる。 Next, when the carbon fiber tube 30 is fitted to the sleeve body 10, it does not face the sleeve body 10 but contacts only the O-ring 20. Therefore, not only the effect of easy assembly can be achieved, but also consumables such as the carbon fiber tube 30 and the O-ring 20 can be easily replaced.

さらに、上記の実施例では、本考案のリング溝122とOリング20の数はそれぞれ1つであるが、スリーブ本体10と炭素繊維管30をより強固に嵌着するために、必要に応じてリング溝122とOリング20の数を適切に増加することができる。 Further, in the above embodiment, the number of the ring groove 122 and the O-ring 20 of the present invention is one, respectively, but in order to more firmly fit the sleeve body 10 and the carbon fiber tube 30, if necessary. The number of ring grooves 122 and O-rings 20 can be increased appropriately.

また、上記の実施例では、該駆動孔は四角孔であり、該作用孔は六角孔である。しかしながら、実際には、該駆動孔と該作用孔は、四角孔、六角孔、八角孔、十二角孔又は六角星状孔のいずれかであってもい。 Further, in the above embodiment, the drive hole is a square hole, and the action hole is a hexagonal hole. However, in practice, the drive hole and the action hole may be any of a square hole, a hexagonal hole, an octagonal hole, a dodecagram hole, or a hexagonal star hole.

以上の内容は、本考案に係る好ましい実施例に過ぎず、本考案の実施範囲を限定するものではなく、当業者が本考案に基づき行った同等変更は、いずれも本考案の範囲に属すべきである。 The above contents are merely preferable examples according to the present invention, and do not limit the scope of implementation of the present invention, and any equivalent changes made by those skilled in the art based on the present invention should belong to the scope of the present invention.
