Self-locking type connector and connection pile

Abstract

The utility model relates to a self-locking type connector and a connection pile. The self-locking type connector includes a minor sleeve, wherein a first internal thread is formed in the minor sleeve; a major sleeve, wherein an inserting cavity is formed in the major sleeve, and a second internal thread is formed in the inserting cavity at one end of the major sleeve that is proximal to the minor sleeve; an inserted link, wherein a first externally threaded connection end in threaded connection with the first internal thread of the minor sleeve is arranged at an axial end of the inserted link, and an inserted end capable of extending into the inserting cavity is formed at the other end of the inserted link; and a locking portion, arranged in the inserting cavity of the major sleeve and used for locking the inserted end. The utility model is ingenious in design, the provided self-locking type connector can rapidly connect an upper connection pile and a lower connection pile, construction time is saved, and the connected upper connection pile and lower connection pile are high in firmness, and especially are good in tensile performance.
