Detailed Description

The invention will be elucidated below on the basis of an embodiment shown in the drawing. The embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is not limited by the following description of the embodiments, but is defined only by the scope of the claims, and includes all modifications that have the same meaning as the scope of the claims and are within the scope of the claims.

A mechanical connecting joint device of the embodiment is used for connecting concrete piles. The structure of the device is shown in figures 1 and 2 and comprises an upper barrel 1, a lower barrel 2, a plunger 3, an upper cutting sleeve 4, a lower cutting sleeve 5, a snap ring 6 and an elastic ring 7. The outer parts of the upper cutting sleeve 4 and the lower cutting sleeve 5 are provided with threads 10, the inner wall of the lower barrel 2 is also provided with threads 10, and the upper cutting sleeve 4 and the lower cutting sleeve 5 are arranged in the lower barrel 2 through the threads 10. The upper cutting sleeve 4 and the lower cutting sleeve 5 are both provided with a clamping groove 11 for placing a clamping table 12 of the clamping ring 6. The upper end surfaces of the upper cutting sleeve 4 and the lower cutting sleeve 5 are both provided with mounting holes 13, and the mounting holes 13 are preferably arranged at positions corresponding to the clamping platforms 12. The number of the mounting holes 13 of the present embodiment is two or more.
