    • PURPOSE: A pressure balance-type expansion joint is provided to prevent non-uniform deformation and damage of first and second and third bellows units because displacement caused by the extension force of a hot blast pipe is uniformly actuated on each portion of first and second sleeves. CONSTITUTION: A pressure balance-type expansion joint(10) comprises first and second sleeves(20,30) and first and second and third bellows units(40,50,60). The first and second sleeves respectively comprises first and second projected portions(21) and first and second guide grooves(22). The first projected portions are formed at a predetermined distance to a circumferential direction. The first guide groove is formed in between the first projected portions. The second projected portions are inserted into the first guide groove between the first projected portions to the circumferential direction. The second guide groove is formed between the second projected portions and the first projected portions are inserted into the second guide groove.
    • 目的:提供一种压力平衡型膨胀接头,以防止第一和第二和第三波纹管单元的不均匀变形和损坏,因为由热风管的延伸力引起的位移在第一和第二套筒的每个部分上被均匀地致动 。 构成:压力平衡型膨胀接头(10)包括第一和第二套筒(20,30)以及第一和第二和第三波纹管单元(40,50,60)。 第一和第二套筒分别包括第一和第二突出部分(21)和第一和第二引导槽(22)。 第一突出部形成在与周向的预定距离处。 第一引导槽形成在第一突出部之间。 第二突出部分在第一突出部分之间沿圆周方向插入第一引导槽中。 第二引导槽形成在第二突出部分之间,并且第一突出部分插入到第二引导槽中。

    • PURPOSE: A flexible tube for a car exhaust tube is provided to prevent the danger such as the leakage of exhaust gas and the like by preventing the abrasion damage of a bellows member with repeatedly contacting by the vibration caused by the traveling. CONSTITUTION: The flexible tube for a car exhaust tube contains:a metal bellows member(10); a spiral groove(21) placed inside of the bellows member(10) in a state of maintaining a specific gap and rolled as a spiral shape; an interlock member(20); a braid member(30); a cap(40) combined by being inserted into the edge of the braid member(30); an annular medium member(50) having its edge fixed to the bellows member(10) and its other edge fixed by being piled up one on another to the inside facing the interlock member(20); and a separation member(60) for interrupting the contact of the bellows member(10) with the interlock member(20).
    • 目的:提供一种用于汽车排气管的柔性管,以通过防止由于行驶引起的振动而反复接触的波纹管构件的磨损而防止诸如排气等的泄漏的危险。 构成:用于汽车排气管的柔性管包括:金属波纹管构件(10); 在保持特定间隙并卷成螺旋形状的状态下放置在波纹管构件(10)的内部的螺旋槽(21) 互锁构件(20); 编织件(30); 通过插入所述编织构件(30)的边缘而组合的盖(40); 环形介质构件(50),其边缘固定到波纹管构件(10),并且其另一边缘通过彼此堆叠固定到面向互锁构件(20)的内侧; 以及用于中断波纹管构件(10)与互锁构件(20)的接触的分离构件(60)。
