The utility model is a kind of pipe clamp structure for having closing function of related what,Its structure mainly includes an at least thread tube body,And thread inboard wall of tube body face define at least one be in cambered surface aspect taper face,And thread tube body system and interior tube body are in the aspect of thread locking,And be defining a pipe clamp element between thread tube body and interior tube body,Wherein,One is then defined on the pipe clamp element to be arranged in parallel angle with taper face to form the interface of face contact and one in corresponding and to clamping interior tube body curved surface,Thereby,When the parallel angle area in taper face increases,The abrasion loss of interface and taper face on pipe clamp element can be effectively reduced,To improve life of product,Simultaneously via pipe clamp element surface curved design,It is able to that interior tube body is allowed to be transformed into face contact by line contact by when packing,Stress suffered by interior tube body is effectively reduced,To promote the service life of interior tube body.本新型為有關於一種具封閉功能之管夾結構，其結構主要包括至少一螺牙管體，而螺牙管體內壁面界定有至少一呈弧面態樣的錐度面，且螺牙管體係與內管體呈螺紋鎖固之態樣，而螺牙管體及內管體間乃界定一管夾元件，其中，所述之管夾元件上則界定有一與錐度面呈平行角度設置以形成面接觸的對接面及一呈相對應且用以夾固內管體的曲面，藉此，當錐度面上的平行角度面積增加時，能有效降低管夾元件上對接面與錐度面的磨耗量，以提高產品壽命，同時經由管夾元件內側的曲面設計，得以讓內管體受迫緊時由線接觸轉變成面接觸，以有效降低內管體所受之應力，來提升內管體的使用壽命。
