    • The present invention discloses a pipefitting and a corresponding assembling structure thereof. The pipefitting has male threads and the corresponding assembling structure has female threads located in positions corresponding to the male threads of the pipefitting such that the pipefitting and the corresponding assembling structure can be assembled together. The improvement of the present invention comprises a first O-ring sleeved onto a front end of the male threads of the pipefitting; a circular section formed on a back end of the male threads; a second O-ring sleeved onto the circular section; and an inner section formed in the corresponding assembling structure in a position corresponding to the circular section of the pipefitting for tightly touching the second O-ring, thereby preventing leakage caused by hydraulic burst pressure inside the corresponding assembling structure.
    • 本发明公开了一种管件及其相应的组装结构。 管接头具有阳螺纹,并且相应的组装结构具有位于对应于管接头的阳螺纹的位置的阴螺纹,使得管接头和相应的组装结构可以组装在一起。 本发明的改进包括套在管接头的阳螺纹的前端上的第一O形环; 形成在阳螺纹的后端的圆形部分; 第二个O形圈套在圆形部分上; 以及在对应的组装结构中形成在与管件的圆形部分相对应的位置以紧紧接触第二O形环的内部部分,从而防止由相应的组装结构内的液压爆破压力引起的泄漏。
