Description

自行車胎用之轉接加壓氣嘴結構Transfer pressurizing air nozzle structure for bicycle tire

本創作係有關於一種轉接氣嘴，尤指一種自行車胎用之轉接加壓氣嘴結構。This creation is about a kind of transfer valve, especially a kind of transfer pressure nozzle structure for bicycle tires.

按，目前自行車輪胎之種類概可區分為『有內胎』及『自行車胎』兩種，不論車體係採用『有內胎』或『無內胎』形式，皆需透過氣嘴達到氣體填充灌入之目的。By the way, the current types of bicycle tires can be divided into two types: "inner tube" and "bicycle tire". Regardless of whether the bicycle system adopts the form of "inner tube" or "tubeless", it needs to be filled with gas through the air nozzle. .

前述無內胎輪組的結構設計上，因無需裝設內胎，故其氣嘴係直接裝設於雙層輪圈上，該雙層輪圈設有相應的內裝配孔與外裝配孔，該氣嘴包含有一氣嘴本體及一設於該氣嘴本體尾端的氣密體，該氣嘴本體外周面設有螺紋部，該氣密體的外徑大於該外裝配孔的孔徑。裝設時該氣嘴本體依序穿過該外裝配孔與該內裝配孔，再以一螺帽與該氣嘴本體外周面的螺紋部螺設鎖固，使該氣密體緊靠於該外裝配孔外側，藉以封閉該外裝配孔，達到止密效果。In the structural design of the aforementioned tubeless wheel set, because there is no need to install an inner tube, its air nozzle is directly installed on the double-layer rim. The double-layer rim is provided with corresponding inner and outer assembly holes. The nozzle includes an air nozzle body and an airtight body arranged at the tail end of the air nozzle body. The outer circumference of the air nozzle body is provided with a threaded part. The outer diameter of the airtight body is larger than the aperture of the outer assembly hole. During installation, the air nozzle body passes through the outer assembly hole and the inner assembly hole in sequence, and then a nut and the threaded part of the outer circumference of the air nozzle body are screwed and locked to make the airtight body abut against the The outer side of the outer assembling hole is used to close the outer assembling hole to achieve the sealing effect.

惟，一般無內胎輪組之氣嘴所能承受的氣壓有限，因而當無內胎輪胎為高壓胎時，常造成無法將胎壓打氣至預定的高壓，亦即不適用於高壓胎，造成騎車者的困擾及影響自行車行駛的安全性。However, the air nozzle of the general tubeless wheel set can withstand limited air pressure. Therefore, when the tubeless tire is a high-pressure tire, it is often impossible to inflate the tire pressure to a predetermined high pressure, that is, it is not suitable for high-pressure tires, causing cycling People’s troubles and affect the safety of bicycle driving.

本創作人有鑑於一般無內胎氣嘴具有上述缺點，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，遂推出本創作。In view of the above-mentioned shortcomings of general tubeless air nozzles, the creator of this creation is based on the idea of thinking and creation.
