Abstract
Description
本創作係與氣動工具之配件有關,更詳而言之係指一種套筒結構。This creation is related to the accessories of pneumatic tools, and more specifically refers to a sleeve structure.
按,在欲將輪圈裝到汽車上或將輪圈自汽車上拆下時,一般會使用氣動工具作為動力源,並透過與對應套筒之對接,而對螺帽進行旋緊或旋鬆。 然,一般與氣動工具對接之套筒,由於需具備一定之剛性以防變形,因此皆係以金屬製成,而套筒在對螺帽進行旋緊或旋鬆之當下,或在作動之前後作業過程中,極容易發生套筒與輪圈產生碰撞之情形,導致輪圈會有刮痕產生,此一情形對於高要求之車主或此輪圈(鋁合金輪圈)為價格極貴之車主而言,極難以接受,使得汽車維修廠(輪胎行)與車主間之糾紛常有耳聞。 是以,有汽車維修廠(輪胎行)會將其他稍軟之物品(如布料)包覆在套筒外周上,以防止刮傷輪圈,但其不僅在使用上不夠便利,且難以伸入輪圈供套筒伸入之孔中,而難以適用。因此,又有業者開發出在套筒上套置一塑膠套之方式,但太薄之塑膠套不具保護作用,而太厚之塑膠套則會無法伸入輪圈上之孔,而反而去削減原有套筒之外徑,使之整體的剛性不足,且塑膠套在與套筒套接之過程係呈緊迫之面接觸,而有組裝上之困難。Press, when you want to install the rim on the car or remove the rim from the car, generally use pneumatic tools as the power source, and through the docking with the corresponding sleeve to tighten or loosen the nut . However, the sleeves that are generally mated with pneumatic tools need to have a certain degree of rigidity to prevent deformation, so they are all made of metal. During the operation, it is very easy to collide between the sleeve and the rim, resulting in scratches on the rim. This situation is for high-demand car owners or this rim (aluminum alloy rim) is very expensive for car owners. In other words, it is extremely difficult to accept, so that disputes between car repair shops (tire dealers) and car owners are often heard. Therefore, some automobile repair shops (tire shops) will wrap other softer items (such as cloth) on the outer circumference of the sleeve to prevent scratching the rim, but it is not only inconvenient in use, and difficult to penetrate The rim is difficult to apply to the hole into which the sleeve extends. Therefore, some manufacturers have developed a way to put a plastic sleeve on the sleeve, but a plastic sleeve that is too thin has no protective effect, and a plastic sleeve that is too thick will not be able to extend into the hole on the rim and cut it instead. The outer diameter of the original sleeve makes the overall rigidity insufficient, and the plastic sleeve is in tight contact with the sleeve during the process of socketing, which makes it difficult to assemble.
有鑑於此,為改善先前技術中,習知套筒容易對輪圈產生刮痕,及在套筒上套置外物會有使用上不夠便利、保護性不佳、難以伸入輪圈內、整體剛性不足及組裝上困難等問題。緣此,本創作乃提供一種套筒結構,包含有一套筒本體、一O形環及一碳纖維管;該套筒本體具有一驅動部及一與該驅動部同軸連接之作用部,該驅動部之外徑大於該作用部之外徑,該驅動部與該作用部之外周面交接處形成有一階部,該驅動部之自由端面往內軸向凹陷有一驅動孔,該作用部之自由端面往內軸向凹陷有一作用孔,該作用部之外周面上環繞有一環槽;該O形環係圈套在該套筒本體之環槽內;該碳纖維管係套置在該套筒本體之作用部外周面上,其一端與該階部抵接,而其內周面與該O形環抵接;藉以達到避免對輪圈產生刮痕、增進使用便利度、加強保護性、適用現有輪圈、維持整體剛性及容易組裝功效。In view of this, in order to improve the prior art, the conventional sleeve is prone to scratches on the rim, and the use of foreign objects on the sleeve will be inconvenient in use, poor protection, and difficult to extend into the rim. Problems such as insufficient overall rigidity and difficulty in assembly. For this reason, this creation provides a sleeve structure that includes a sleeve body, an O-ring and a carbon fiber tube; the sleeve body has a driving part and an action part coaxially connected with the driving part. The driving part The outer diameter is greater than the outer diameter of the acting part. The driving part and the outer peripheral surface of the acting part form a stepped part. An action hole is recessed in the inner axial direction, and a ring groove is surrounded on the outer circumference of the action portion; the O-ring is sleeved in the ring groove of the sleeve body; the carbon fiber tube is sleeved on the action portion of the sleeve body One end of the outer peripheral surface abuts against the step, and its inner peripheral surface abuts against the O-ring; in order to avoid scratches on the rim, improve convenience, enhance protection, and adapt to existing rims, Maintain the overall rigidity and easy assembly function.
為使貴審查委員能對本創作之特徵與其特點有更進一步之了解與認同,茲列舉以下之實施例並配合圖式說明如下:
請參閱第一圖至第三圖,係本創作一較佳實施例所提供之一種套筒結構100,主要包含有一套筒本體10、一O形環20及一碳纖維管30,其中:
請參閱第一圖至第三圖,該套筒本體10,係為一體製成之圓柱形筒體。該套筒本體10具有一驅動部11及一與該驅動部11一體同軸連接之作用部12,且該驅動部11之外徑大於該作用部12之外徑,使於該驅動部11與該作用部12之外周面交接處形成有一階部13,該驅動部11之自由端面上自軸心位置往內軸向凹陷延伸有一驅動孔111,於本實施例中該驅動孔111為四角孔,該驅動部11之外周面上形成有一徑向貫穿圓心之定位孔112,該作用部12之自由端面上自軸心位置往內軸向凹陷延伸有一作用孔121,於本實施例中該作用孔121為六角孔,該作用部12之外周面上環繞形成有一環槽122。
請參閱第一圖至第三圖,該O形環20,係由橡膠或其他具彈性之材料所一體製成之圓形環體。該O形環20係圈套在該套筒本體10之環槽122內,僅稍微地局部凸出於該環槽122外。
請參閱第一圖至第三圖,該碳纖維管30,係由碳纖維所製成之軸向中空管體。該碳纖維管30係套置在該套筒本體10之作用部12外周面上,並由其一端與該階部13抵接,而由其內周面與該O形環20抵接,使該碳纖維管30之外周面與該驅動部11之外周面呈平齊,而該碳纖維管30之內周面則與該作用部12之外周面距一間隙。該碳纖維管30之管壁厚度係位在0.3mm~0.8mm之間。
是以,上述即為本創作一較佳實施例所提供套筒結構100之各部構件及其組合方式之介紹,接著再將其使用特點介紹如下:
首先,由於碳纖維管30能製出極薄之管壁,且在管壁極薄之狀態下仍保有一定之硬度(其硬度仍低於金屬之硬度)。因此,極薄管壁之碳纖維管30在套置在該套筒本體10上後,其整體之外徑並不會增加太多,使能適用在現有之輪圈上,而整體外徑並未增加太多,便無須削減原有套筒本體10之外徑,而能保持整體之剛性,且碳纖維管30自身之硬度亦能增加抗摩擦損耗效果,以增加使用壽命,以讓本創作不僅能避免對輪圈所造成之損傷,更能具備使用便利、保護性佳、能適用現有輪圈及維持整體剛性等功效。
其次,由於該碳纖維管30在套置於該套筒本體10上時,並不會與套筒本體10產生面對面之接觸,而僅係與O形環20接觸。因此,不僅能達到便於組裝之功效,亦能便於更換碳纖維管30與O形環20等耗材。
再者,雖然上述實施例中,本創作之環槽122及O形環20之數量各為一個,但為讓套筒本體10與碳纖維管30能更緊固套置,可依實際需求適量增加環槽122及O形環20之數量。
另外,雖然上述實施例中,該驅動孔為四角孔,而該作用孔為六角孔。但實際上,該驅動孔與該作用孔皆可為四角孔、六角孔、八角孔、十二角孔或六角星形孔中之任何一種。
以上所揭,僅為本創作所提供之較佳實施例而已,並非用以限制本創作之實施範圍,凡本技術領域內之相關技藝者根據本創作所為之均等變化,皆應屬本創作所涵蓋之範圍。In order to enable your reviewer to have a better understanding and recognition of the features and characteristics of this creation, the following examples are listed below in conjunction with the schematic descriptions:
