Description
本發明係有關於一種拆卸工具，尤指一種適用於無牙式頭碗之自行車頭碗拆卸工具。 The invention relates to a disassembly tool, in particular to a bicycle head bowl dismounting tool suitable for a toothless head bowl.
按，頭碗係用於藉由使用者轉動車頭而帶動前輪轉向的交通工具。以自行車為例，其前叉豎管係透過二頭碗而可相對轉動地穿設於車身之前管，且前叉與把手及前輪固定，因此使用者可藉由控制把手帶動前輪相對車身左右偏轉，目前自行車頭碗主要有兩種類型：有牙式頭碗及無牙式頭碗，並且由於無牙式頭碗係利用強迫塞結方式固定於前管之上端及下端內，因為當該無牙式頭碗欲拆卸時，需使用特殊的拆卸工具，本創作即是針對無牙式頭碗拆卸工具所存在的問題加以探討。 Press, the head bowl is used to drive the front wheel to turn the vehicle by turning the front of the vehicle. Taking a bicycle as an example, the front fork standpipe is rotatably disposed in the front tube of the vehicle body through the two-head bowl, and the front fork is fixed with the handle and the front wheel, so that the user can drive the front wheel to deflect left and right relative to the vehicle body by controlling the handle. At present, there are two main types of bicycle head bowls: a toothed head bowl and a toothless head bowl, and because the toothless head bowl is fixed in the upper end and the lower end of the front tube by forced plugging, because when there is no When the toothed head bowl is to be disassembled, a special disassembly tool is required. This creation is to discuss the problems existing in the toothless head bowl removal tool.
如第九圖所示，即為一種習知自行車頭碗拆卸工具，其係一中空圓棒10，該中空圓棒10具有一抵推端101及一受力端102，該抵推端101往受力端102方向間隔剖設有複數切溝103，形成複數具有彈性之抵推片體104，該複數抵推片體104往抵推端101逐漸向外擴張，使抵推端10的口徑大於中空圓棒101之直徑。 As shown in the ninth figure, it is a conventional bicycle head bowl dismounting tool, which is a hollow round bar 10 having a pushing end 101 and a receiving end 102, and the pushing end 101 is The plurality of grooving grooves 103 are formed in the direction of the force receiving end 102, and a plurality of elastic urging pieces 104 are formed. The plurality of urging pieces 104 are gradually expanded outward toward the pushing end 101, so that the diameter of the abutting end 10 is larger than The diameter of the hollow round bar 101.
使用時，如第十圖及第十一圖所示，將該複數抵推片體104往中心壓縮，使中空圓棒10的抵推端10口徑縮小，以便穿過自行車前管20上端或下端組設之頭碗30內孔伸入前管20中，當中空圓棒10的複數抵推片 體104伸入前管20中後，該複數抵推片體104便藉由本身的彈性回復原狀，使抵推端101的口徑回復原本大小，以該抵推端101抵於自行車前管20上端或下端組設之頭碗30內端面，利用器具敲擊中空圓棒10的受力端102，即可將該頭碗30敲下，於不傷害前管20的情形下使該頭碗30與前管20分離。 In use, as shown in the tenth and eleventh figures, the plurality of pressing pieces 104 are compressed toward the center, so that the abutting end 10 of the hollow round bar 10 is reduced in diameter so as to pass through the upper or lower end of the bicycle front tube 20. The inner hole of the set head 30 extends into the front tube 20, and when the hollow round bar 10 is plural, the push piece is pushed. After the body 104 is inserted into the front tube 20, the plurality of urging pieces 104 are restored to their original shape by the elasticity of the body 104, and the diameter of the pushing end 101 is restored to the original size, so that the pushing end 101 abuts the upper end of the front tube 20 of the bicycle. Or the inner end surface of the head bowl 30 set at the lower end, and the force receiving end 102 of the hollow round rod 10 is tapped by the instrument, the head bowl 30 can be knocked down, and the head bowl 30 can be made without damaging the front tube 20 The front tube 20 is separated.
惟，該習知自車頭碗拆卸工具，其抵推端101的口徑為固定式，然而頭碗30卻有多種尺寸規格，因而需準備多把不同口徑的自行車頭碗拆卸工具，方可適用於各種規格的頭碗30，如此不但成本高，收納佔用空間，並且使用時需依照頭碗30規格選用合適的口徑的自行車頭碗拆卸工具，相當麻煩不便。 However, the conventional self-bowl bowl removing tool has a fixed diameter of the pushing end 101. However, the head bowl 30 has various sizes and specifications, so it is necessary to prepare a plurality of bicycle head bowl dismounting tools of different calibers. The head bowl 30 of various specifications is not only costly, but also requires a space for storage, and it is necessary to use a bicycle head bowl dismounting tool of a suitable caliber according to the size of the head bowl 30, which is quite troublesome and inconvenient.
本發明人有鑑於習知自行車頭碗拆卸工具，其抵推端的口徑為固定式，以致需準備多把方足以應付各種規格的頭碗，成本高，且使用上具有諸多的不便，是以乃思及創作的意念，經多方探討與試作樣品試驗，及多次修正改良後，終推出本發明。 The present inventors have in view of the conventional bicycle head bowl dismounting tool, the diameter of the pushing end is fixed, so that it is necessary to prepare a plurality of heads sufficient for various specifications, the cost is high, and the use has many inconveniences. After thinking about the idea of creation, after many discussions and trial sample tests, and many corrections and improvements, the invention was finally introduced.
