Abstract
Description
本發明係與自行車有關;特別是指一種可快速拆解以取下車輪的自行車快拆結構。The invention relates to bicycles; in particular, it refers to a bicycle quick disassembly structure that can be quickly disassembled to remove wheels.
自行車種類眾多,其用於穿過車輪花轂並結合在車架前叉或是後叉上的軸桿式快拆結構亦不相同。其中,登山車或是下坡車相對公路車在騎乘時因承受騎乘中較大的衝擊力,相對地需要使用抗衝擊力較高的軸桿,此類軸桿的一端通常設置有外螺紋段,利用外螺紋段鎖入車架前叉或是後叉上的螺孔以強化結合的穩固性並增加抗衝擊力。軸桿的另一端為結合扳手的操作端,扳轉扳手時可帶動軸桿轉動,以驅使軸桿的外螺紋段相對於車架上的螺孔而旋緊或是旋鬆,據以實現車輪可快速拆離或固定於車架上的目的。然而,上述軸桿之操作端以扳手方式操作,在於車輪穩固地安裝於車架後,其扳手的位置經常被旋轉至不恰當的位置,易與周遭零組件產生干擾,導致騎乘上安全問題。There are many types of bicycles, and the axle-type quick-release structure used to pass through the wheel hub and connect to the front fork or rear fork of the frame is also different. Among them, mountain bikes or downhill bikes bear greater impact during riding than road bikes, and relatively need to use shafts with higher impact resistance. One end of this type of shaft is usually provided with an outer shaft. The threaded section uses the external threaded section to lock into the screw holes on the front fork or rear fork of the frame to strengthen the stability of the combination and increase the impact resistance. The other end of the shaft is the operating end of the combination wrench. When the wrench is turned, the shaft can be driven to rotate to drive the external threaded section of the shaft to tighten or loosen relative to the screw hole on the frame, so as to realize the wheel It can be quickly detached or fixed on the frame. However, the operating end of the above-mentioned shaft is operated by a wrench. After the wheel is firmly installed on the frame, the position of the wrench is often rotated to an improper position, which easily interferes with surrounding components and causes safety problems during riding. .
為改善前述問題,業者開發出一種改良後的快拆結構,請參閱TWI622515號揭示的「可隱藏驅動柄之快拆結構」,該案之驅動柄的兩側設置可供容置卡摯件的導槽,而使該驅動柄可在該導槽前、後兩端的長度範圍內滑移,且該導槽後端受卡摯件限制而使該驅動柄無法脫離,同時該驅動柄可以該卡摯件的鋼珠為轉軸,使軸桿可以左右偏轉而控制旋緊或旋鬆於車架前叉或是後叉上的螺孔。In order to improve the aforementioned problems, the industry has developed an improved quick release structure. Please refer to the "Quick release structure capable of concealing the drive handle" disclosed in TWI622515. In this case, there are two sides of the drive handle that can accommodate the card holder. Guide groove, so that the drive handle can slide within the length range of the front and rear ends of the guide groove, and the rear end of the guide groove is restricted by the catch so that the drive handle cannot be separated, and the drive handle can The steel ball of the stopper is the rotating shaft, so that the shaft can be deflected left and right to control the screw hole on the front fork or the rear fork of the frame.
藉由上述結構,雖可改善扳手式快拆結構所產生的安全問題,卻也有著零件過多、製造成本高且組裝困難等問題。With the above structure, although the safety problem caused by the wrench-type quick release structure can be improved, it also has the problems of excessive parts, high manufacturing cost, and difficulty in assembly.
有鑑於此,本發明之目的在於提供一種自行車快拆結構,不僅減少零件,更可降低製造成本以及讓組裝更為簡易。In view of this, the purpose of the present invention is to provide a bicycle quick-release structure, which not only reduces parts, but also reduces manufacturing costs and makes assembly easier.
緣以達成上述目的,本發明提供的一種自行車快拆結構包括有一快拆桿、一軸柄及一銷。該快拆桿具有一桿身及一端蓋,該桿身沿著軸向設置一軸孔,該端蓋具有一剖槽及一連通該剖槽之穿孔,該剖槽係與該軸孔的一端相連通;該軸柄具有一貫穿一柄身的長槽孔,該柄身穿經該剖槽而容置於該軸孔中;該銷,係穿設於該穿孔及該長槽孔;藉此,當該軸柄向外拉出時,該長槽孔可抵於該銷,使該軸柄不脫出於該剖槽,且可扳轉該軸柄。In order to achieve the above-mentioned objective, a bicycle quick-release structure provided by the present invention includes a quick-release lever, a shaft handle and a pin. The quick release rod has a shaft and an end cover, the shaft is provided with a shaft hole along the axial direction, and the end cover has a slit and a through hole communicating with the slit, and the slit is connected with one end of the shaft hole The shaft has a long slot through a shaft, the shaft passes through the slit and is accommodated in the shaft hole; the pin is drilled through the perforation and the long slot; thereby When the shaft handle is pulled out, the long slot hole can abut the pin, so that the shaft handle does not fall out of the cut groove, and the shaft handle can be turned.
本發明之效果在於向外拉出該軸柄時,該軸柄以該銷為支點作扳轉,俾使該軸柄以輕易地被驅使而帶動該快拆桿旋轉,以快速地將車輪自車架拆離,或是組裝至車架上。The effect of the present invention is that when the axle is pulled out, the axle is turned with the pin as a fulcrum, so that the axle can be easily driven to drive the quick release lever to rotate, so as to quickly turn the wheel from The frame is detached or assembled to the frame.
為能更清楚地說明本發明,茲舉較佳實施例並配合圖式詳細說明如後。請參閱圖1至圖3所示,為本發明第一較佳實施例之自行車快拆結構100包括:一快拆桿10、一軸柄20、一銷30、一卡摯件40及一定位結構50。該快拆桿10具有一桿身12及一端蓋14,該快拆桿10具有沿著該桿身12的長軸向設置的一軸孔16,該桿身12表面於一端形成一外螺紋段122,該桿身12表面於另一端以可拆離的方式與車架的前叉或後叉結合,在本實施例中,實現桿身12以可拆離的方式與車架的前叉或後叉結合的結構包括在桿身12相對於該外螺紋段122的另一端形成一螺紋段124,車架的前叉或後叉設有螺孔,請配合圖4所示,於本實施例係以後叉60具有螺孔62與該螺紋段124螺合為例。In order to explain the present invention more clearly, the preferred embodiments are described in detail in conjunction with the drawings. Please refer to Figures 1 to 3, which is a bicycle
該快拆桿10之端蓋14在其軸向上分別自頂面及底面向內設有一剖槽141及一螺孔142,且透過一通孔143連通該剖槽141及該螺孔142;該桿身12一端的外螺紋段122即鎖入該螺孔142中而與端蓋14連結成一體。該端蓋14並且具有呈徑向設置的一螺孔144及一穿孔145,其中螺孔144位於該剖槽141的下方處並連通該螺孔142,穿孔145則是連通該剖槽141,在該桿身12與該端蓋14連結成一體時,透過以螺栓為例的卡摯件40鎖入螺孔144且卡摯件40一端抵接該桿身12的外螺紋段122時可確保該桿身12與端蓋14穩固連結。The
上述實施例之快拆桿10是由桿身12及端蓋14兩個部件組合而成,然於其他實務中,桿身及端蓋可以是一體成形的結構。The
該軸柄20可移動地穿設於該桿身12之軸孔16中,其具有一柄身22及一連接於該柄身22一端的柄頭24。該柄身22具有沿著長軸向設置並且貫穿柄身身部的長槽孔222,該柄身22***該快拆桿10的軸孔16中,該銷30穿過該端蓋14的穿孔145同時穿過長槽孔222,使得該軸柄20只能在長槽孔222兩端之間的距離移動,前述銷30與穿孔145之間可以是採緊配合方式搭配,以防銷30的不慎脫落,當然亦可選擇以螺合方式配置,另外亦可採用黏著方式配置。The
該定位結構50在本實施例中是由至少一定位孔52及至少一定位塊54組成,其中,定位孔52及定位塊54的數量以二個為例,且定位孔52係設置在該柄頭22,定位塊54是以可受壓變形的材料製成,例如但不限於橡膠。定位塊54係塞設於定位孔52中,且定位塊54的兩端凸露於定位孔52外,當軸柄20***軸孔16中,且軸柄20的柄頭24對應位於該剖槽141內時,定位塊54凸露的兩端將抵接剖槽141的內壁,並因為受到擠壓而變形,藉以產生較大的摩擦阻力,以使軸柄20不至於相對快拆桿10而鬆脫。In this embodiment, the
以上為本發明較佳實施例之自行車快拆結構100的結構說明,接著說明其使用方式如後。The above is the structural description of the bicycle
圖4係表示自行車快拆結構100處於常態,所述常態是指自行車的車輪透過該自行車快拆結構100而穩固地結合於自行車的車架上,在此狀態下,軸柄20之柄身22***軸孔16,軸柄20之柄頭24對應位於該剖槽141內,銷30的位置恰位於該長槽孔222靠近柄頭24的一端。Fig. 4 shows that the bicycle
圖5揭示使用者將軸柄20相對快拆桿10向外拉出,在移動至其長槽孔222遠離柄頭22的一端抵接該銷30時,使該軸柄20無法相對該快拆桿10脫離。接著,使用者以該銷30為支點,剖槽141為活動空間,將軸柄20往上或是往下搬動至如圖6所示的狀態,使得軸柄20與快拆桿10的軸線之間形成有夾角,之後使用者以順時針或是逆時針方向扳轉軸柄20,透過軸柄20的柄身24抵靠剖槽141的內壁而推動快拆桿10旋轉,使得快拆桿10之桿身12的外螺紋段122能自後叉60的螺孔62鬆脫,至此即可取下自行車快拆結構100以續行車輪的卸下作業。Figure 5 shows that the user pulls the
綜上所述,本創作透過軸柄的長槽孔,在拉出軸柄時可抵靠於銷的設計,驅使轉動軸柄而達到車輪快速拆離或固定於車架,不僅簡化組裝的零組件,亦可讓組裝過程更為簡便,且在製造成本上也更為節省,讓產品更具競爭優勢。To sum up, this creation uses the long slotted hole of the shaft handle to abut the pin when the shaft handle is pulled out, driving the shaft handle to quickly detach or fix the wheel to the frame, which not only simplifies the assembly Components can also make the assembly process easier and save more on manufacturing costs, giving products a more competitive advantage.
