Connection device and connection method for axial connection for two rod elements
The invention provides a connection device and a connection method for axial connection for two rod elements. The connection device for axial connection for the two rod elements comprises a hollow sleeve, a first rod element and a second rod element, wherein the hollow sleeve is provided with an axially-penetrating through hole, and a left internal thread and a right internal thread are formed onthe inner-diameter surfaces of two opposite ends separately; a left external thread is formed at one end of the first rod element; a right external thread is formed at one end of the second rod element; the left external thread and the right external thread are spirally combined onto the left internal thread and the right internal thread correspondingly; according to the device, an unthreaded section can be formed in the hollow sleeve, or a gasket can be provided and axially arranged in the through hole of the hollow sleeve, and the hollow sleeve is rotated to drive the first rod element and the second rod element to move towards the mutually opposite directions simultaneously until the end parts of the first rod element and the second rod element are abutted against the gasket; or, an unthreaded projection end is formed on the end part of one of the first rod element and the second rod element, and the hollow sleeve is rotated until the projection end is abutted against the end part of the other rod element.
本发明提供一种将两杆件轴向连接的连接装置及其连接方法，包括：中空套筒，其具有轴向贯通的通孔，且相对两端的内径表面分别具有左内螺纹与右内螺纹；第一杆件，其一端形成有左外螺纹；第二杆件，其一端形成有右外螺纹；将左、右外螺纹分别螺旋组合于左、右内螺纹；其中，所述装置可以在中空套筒中形成一无螺纹段，或者可以提供一垫片，将其轴向地置入中空套筒的通孔中，并旋转中空套筒以同时带动第一、二杆件往彼此相对的方向移动，直到第一、二杆件的端部抵触于垫片；或者，第一与第二杆件其一的端部形成有不具螺纹的突出端，并旋转中空套筒直到所述突出端与另一杆件的端部彼此抵触。
