Description
本發明係關於一種氣動工具快速接頭之組接氣密結構,主要是針對氣動工具與空壓設備之輸氣管的連接需求而設計,透過其快速接頭與氣動工具本體鎖接結合之接合槽內部的斜錐環塞部設計,使其在快速接頭鎖接於氣動工具本體時,可輕易取得氣密組接關係,免除習知額外密止環之使用,據以賦予更佳之產業利用價值者。 The invention relates to a combined airtight structure of a pneumatic tool quick joint, which is mainly designed for the connection requirement of a pneumatic tool and a gas pipe of a pneumatic device, and the inside of the joint groove which is coupled with the pneumatic tool body through the quick joint thereof The tapered cone plug is designed to make it easy to obtain a hermetic connection when the quick connector is locked to the pneumatic tool body, thereby eliminating the use of the conventional extra-closed ring and thereby giving better industrial value.
按,噴漆槍、氣動起子等氣動工具,顧名思義,即是以空壓設備所輸送的氣流作為動力,藉以驅動其功能構件而達成預期的操作功能,而為了方便氣動工具與空壓設備的連接結合,通常將其連接部位採快速接頭設計,藉以提供快速插結與拔離之便利性。 According to the pneumatic tools such as spray guns and pneumatic screwdrivers, as the name suggests, the airflow sent by the air compressors is used as the power to drive the functional components to achieve the desired operational functions, and the connection between the pneumatic tools and the air compressors is facilitated. The joints are usually designed with a quick joint to provide quick insertion and removal.
而此類快速接頭,因經常會面臨與空壓設備之輸氣管的反覆插拔動作,所以在一段時間後,難免會有結構磨損現象,影響其插結的氣密性,為了避免影響其動力傳輸,此類快速接頭通常並不會與氣動工具採一體式結構設計,而是將快速接頭採分離式獨立製造後,再加以鎖接結合於氣動工具本體所預製的進氣管端,並在兩者的鎖接部位利用密止環來取得氣密關係,使其得以透過快速接頭與空壓設備的插接而取得理想的供氣驅動關係,同時可賦予快速接頭磨損時之可替換性者。 Such quick joints often face the reverse insertion and removal of the gas pipelines of the air compressors, so after a period of time, structural wear and tear will inevitably occur, affecting the airtightness of the plugging, in order to avoid affecting its power. Transmission, such quick couplings usually do not have a one-piece design with pneumatic tools, but the quick joints are separately manufactured separately, and then locked and coupled to the intake pipe end prefabricated by the pneumatic tool body, and The locking part of the two uses a tight ring to obtain a gas-tight relationship, so that the quick connection and the air pressure device can be inserted to obtain an ideal air supply driving relationship, and at the same time, the replacement of the quick joint wear can be imparted. .
惟,前述快速接頭與氣動工具本體的進氣管在組接上,必須 利用密止環作為止密構件,在鎖合過程中若施力不當,可能影響其氣密效果,甚至損及密止環的結構,不但增加成本與組配的麻煩外,更因該等密止環容易有磨損及質變問題,導致有使用壽命的限制,實不利於產業上之利用性與實用價值,有必要再設法加以解決改善者。 However, the aforementioned quick joint and the intake pipe of the pneumatic tool body are connected, The use of a dense ring as a stop member, if improperly applied during the locking process, may affect its airtight effect, or even damage the structure of the tight ring, which not only increases the cost and the trouble of assembly, but also because of the density. The ring is prone to wear and quality problems, resulting in a limitation of service life, which is not conducive to industrial utilization and practical value, and it is necessary to try to solve the improvement.
有鑑於習知氣動工具本體之進氣管與快速接頭的組接結合上,必須利用密止環等構件取得氣密效果所衍生之問題與缺失,發明人特著手進行研究解決之道,基於其從事相關產業之多年經驗與技術,進而研發出本發明之組接氣密結構。 In view of the combination of the intake pipe and the quick joint of the conventional pneumatic tool body, it is necessary to use the components such as the seal ring to obtain the problems and lack of the airtight effect, and the inventor specially studies and solves the problem based on the Engaged in years of experience and technology in related industries, and then developed the airtight structure of the present invention.
為解決習知氣動工具有快速接頭組接必須採密止環取得氣密效果所可能衍生之問題與缺失,本發明乃利用於快速接頭接合槽內部通孔週緣所一體成型之斜錐狀環塞部設計,使其將快速接頭鎖接於氣動工具本體的進氣管時,得以該環塞部塞抵於進氣管的內壁,據以取得絕佳之氣密關係,免除額外之密止環使用者。 In order to solve the problems and disadvantages that the conventional pneumatic tools have the quick joint assembly, it is necessary to obtain the airtight effect of the sealing ring. The present invention is a tapered tapered ring plug which is integrally formed on the periphery of the through hole of the quick joint engaging groove. The design is such that when the quick connector is locked to the intake pipe of the pneumatic tool body, the ring plug is inserted against the inner wall of the intake pipe, thereby obtaining an excellent airtight relationship and eliminating the extra tightness. Ring user.
