Seamless connecting piece
The invention relates to a seamless connecting piece, which comprises a small sleeve; a first internal thread is formed in the base; an insertion cavity is formed in the large sleeve, and an internal thread is formed in the insertion cavity close to one end of the small sleeve; one axial end of the insertion rod is provided with an external thread connecting end in threaded connection with the small sleeve, and the other end of the insertion rod forms an insertion end capable of extending into the insertion cavity; the middle sleeve is provided with an external thread in threaded connection with the internal thread of the large sleeve and axially abuts against the small sleeve; the elastic part is arranged in the large sleeve and is used for locking the inserting end; the elastic abutting piece is assembled with the elastic part in a matched mode and arranged in the limiting sleeve. The limiting sleeve is connected with the middle sleeve in a matched and clamped mode; the inner sleeve is arranged in the large sleeve; the device is simple in structure, the middle sleeve and the limiting sleeve are improved, assembly can be simplified, cost can be reduced, and the device is a pre-assembly part and convenient to manage.
本发明涉及一种无缝式连接件，包括：小套筒；其内部形成有第一内螺纹；大套筒，其内部形成有插接腔，靠近小套筒一端的插接腔内形成有内螺纹；插杆，其轴向一端具有与所述小套筒螺接的外螺纹连接端，另一端形成可伸入所述插接腔中的插接端；中间套筒，具有与大套筒的内螺纹螺接的外螺纹且轴向抵接小套筒；弹性部，内置于所述大套筒内用以锁止插接端；弹性抵接件，与弹性部配合装配，内置于限位套筒内；限位套筒，与中间套筒相适配卡接；内置于大套筒内；本发明结构简单，对中间套筒和限位套筒的改进，可简化装配，降低成本，且为预组装件，方便管理。
