Description

Catheters for vehicles

本發明係有關於一種車輛用導管。The invention relates to a catheter for a vehicle.

一般自行車之煞車裝置及變速裝置係藉由一導線以牽引控制，該導線包括一內線及一套設於該內線外周之導管。該導管供該內線穿設使該內線可於該導管之內部空間滑動，並提供防潮及抗衝擊等效果以保護該內線。Generally, the brake device and the speed change device of a bicycle are traction controlled by a wire. The wire includes an inner wire and a set of conduits arranged on the outer periphery of the inner wire. The catheter is used for the inner wire to pass through, so that the inner wire can slide in the inner space of the catheter, and provides moisture-proof and impact-resistant effects to protect the inner wire.

習知之導管包括一內管，該內管通常係以塑膠材料製成以提供平滑之內周面，利於該內線於該內管中滑移致動。然，該內管亦具有平滑之外周面而不利於與其他層體結合，導致該內管與設於其外周之層體易於使用時相錯位，結構穩定度不佳。The conventional catheter includes an inner tube, and the inner tube is usually made of a plastic material to provide a smooth inner peripheral surface, which facilitates the sliding and actuation of the inner wire in the inner tube. However, the inner tube also has a smooth outer peripheral surface, which is not conducive to combining with other layer bodies, causing the inner tube and the layer body provided on the outer circumference to be easily misaligned during use, and the structural stability is not good.

因此，有必要提供一種新穎且具有進步性之車輛用導管，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive vehicle catheter to solve the above-mentioned problems.

本發明之主要目的在於提供一種車輛用導管，其內管可供與其他層體穩定接合。The main purpose of the present invention is to provide a catheter for a vehicle, the inner tube of which can be stably joined with other layers.

為達成上述目的，本發明提供一種車輛用導管，包括：一內管，包括複數螺旋地延伸凸設於該內管之外周面之旋凸部，該複數旋凸部相間隔設置，且該複數旋凸部之相鄰二者之間界定一旋凹部。In order to achieve the above object, the present invention provides a catheter for a vehicle, including: an inner tube, including a plurality of spiral convex portions extending spirally and protruding from the outer peripheral surface of the inner tube, the plurality of spiral convex portions are arranged at intervals, and the plurality of spiral convex portions are arranged at intervals. A spiral concave portion is defined between adjacent two of the spiral convex portion.

以下僅以實施例說明本發明可能之實施態樣，然並非用以限制本發明所欲保護之範疇，合先敘明。The following examples are only used to illustrate the possible implementation aspects of the present invention, but they are not intended to limit the scope of protection of the present invention, and are described first.

請參考圖1至4，其顯示本發明之一較佳實施例，本發明之車輛用導管1包括一內管10，該內管10包括複數螺旋地延伸凸設於該內管10之外周面之旋凸部11，該複數旋凸部11相間隔設置，且該複數旋凸部11之相鄰二者之間界定一旋凹部12。其中，該複數旋凸部11可為一連續延伸凸起之多個區段，亦可分別地設於該內管10之外周面。於使用時，該內管10可供容置一內線2，該內管10之外周面可與其他層體較穩定地相接合。Please refer to FIGS. 1 to 4, which show a preferred embodiment of the present invention. The vehicle catheter 1 of the present invention includes an inner tube 10, and the inner tube 10 includes a plurality of spirally extending and projecting on the outer circumference of the inner tube 10 In the convoluted part 11, the plurality of convoluted parts 11 are spaced apart, and a convoluted part 12 is defined between the two adjacent ones of the plurality of convoluted parts 11. Wherein, the plurality of spiral protrusions 11 can be a plurality of segments continuously extending and protruding, or they can be separately provided on the outer peripheral surface of the inner tube 10. When in use, the inner tube 10 can accommodate an inner wire 2, and the outer peripheral surface of the inner tube 10 can be more stably joined with other layers.

該導管1另包括一金屬層20，該金屬層20包括至少一沿該內管10之一軸向繞設於該內管10外周之線材21，各該線材21部分地容設於一該旋凹部12，可避免該至少一線材21與該內管10相互錯位。該金屬層20之厚度較佳大於該內管10之厚度，增加該導管1之機械強度。The catheter 1 further includes a metal layer 20. The metal layer 20 includes at least one wire 21 wound around the outer circumference of the inner tube 10 along an axial direction of the inner tube 10, and each of the wires 21 is partially accommodated in a spiral The recess 12 can prevent the at least one wire 21 and the inner tube 10 from being misaligned with each other. The thickness of the metal layer 20 is preferably greater than the thickness of the inner tube 10 to increase the mechanical strength of the catheter 1.

詳細說，該至少一線材21包括複數節段211，各該節段211分別對應於一該旋凹部12；該複數節段211之相鄰二者之間具有一間隙212，各該旋凸部11為脊狀且至少部分嵌設於一該間隙212，使該至少一線材21可與該內管10穩定結合。於本實施例中，該至少一線材21為一扁金屬線，該複數節段211之相鄰二者相抵接以較全面地包覆該內管10，增加結構強度且便於彎折配置。於其他實施例中，該至少一線材亦可依需求選用圓形、橢圓形或方形等其他形狀之金屬線或包括複數條金屬線；該複數節段亦可相間隔設置；各該旋凸部亦可依配置需求而呈梯形、矩形或弧形凸出。In detail, the at least one wire 21 includes a plurality of segments 211, and each of the segments 211 corresponds to a spiral concave portion 12; there is a gap 212 between adjacent two of the plurality of segments 211, and each spiral convex portion 11 is a ridge and is at least partially embedded in a gap 212 so that the at least one wire 21 can be stably combined with the inner tube 10. In this embodiment, the at least one wire 21 is a flat metal wire, and adjacent two of the plurality of segments 211 abut to cover the inner tube 10 more comprehensively, increasing the structural strength and facilitating bending configuration. In other embodiments, the at least one wire can also be made of metal wires of other shapes such as round, oval, or square, or include a plurality of metal wires; the plurality of segments can also be arranged at intervals; each of the spiral protrusions It can also protrude in a trapezoidal, rectangular or arc shape according to the configuration requirements.

該導管1另包括一包覆於該金屬層20外之外層30，可固定該金屬層20並避免磨耗、鏽蝕。較佳地，該至少一線材21徑向嵌入該外層30，該至少一線材21嵌入該外層30之深度不小於該旋凹部12之深度，可增加各層之間結合的穩定度以避免相互錯動。該金屬層20之厚度大於該外層30之厚度，避免該外層30厚度過大而使該導管1不易彎撓、安裝。The catheter 1 further includes an outer layer 30 covering the metal layer 20, which can fix the metal layer 20 and avoid abrasion and corrosion. Preferably, the at least one wire 21 is embedded in the outer layer 30 radially, and the depth of the at least one wire 21 embedded in the outer layer 30 is not less than the depth of the convoluted portion 12, which can increase the stability of the bonding between the layers to avoid mutual misalignment . The thickness of the metal layer 20 is greater than the thickness of the outer layer 30 to prevent the outer layer 30 from being too thick and making the catheter 1 difficult to bend and install.
