Abstract

The invention relates to mechanical engineering, to locking threaded connections. The goal is to enhance operational capabilities. The threaded connection includes a pin 3 mounted in the diametrical groove of the threaded rod 1 and the diametral opening of the nut 2 aligned with it. At the end of the nut 2, diametrical slots are made connected to the diametrical holes. In the hole, aligned with the groove of the rod, the sleeves 5 are mounted on the linch pin 3. This allows the linch pin 3 to be installed from the end face of the threaded joint, followed by the linchpin moving along its axis and provides ease of installation in a hard-to-reach place. 2 Il.

The invention relates to mechanical engineering and can be used for locking nuts on fasteners in hard-to-reach places of nodes.

The aim of the invention is to enhance the operational capabilities by providing a clevis mounting in places with limited access.

FIG. 1 shows a threaded connection; in fig. 2 is a view A of FIG. 1. i The threaded connection contains a threaded rod I with a nut 2 screwed on it, and also a cotter pin 3 with a ring and two bend ends, mounted in the diametric groove of the threaded rod 1 and combined with There are 12 diametrically located slots 4 connected to twelve circular holes, in which cylindrical sleeves 5 are fitted on | This outer diameter of the sleeves 5 is greater than the width of the PA and on the threaded rod 1 and the slots 4 on the end of the nut 2. The groove width of the threaded rod 1 and the cuts on the end surface of the nut 2 is jneHbi not less than the diameter of the linch pin 3. The axes of the protrusion coincide with the axes of the holes on the nut K 2

The device works as follows; ZOM.

 The threaded rod 1 is screwed up; the nut 2 is so that after tightening the groove on the rod;

linch pin 3. Pin 3 with bushing 5 is installed from the end of the nut 2 in its slot on the end surface and the groove of the threaded rod 1. The sleeve 5 is inserted into the diametral hole on the side surface of the nut 2, and the pin 3 is moved as far as it will go along its axis . After that, the bend ends of the pin 3 put on the second sleeve 5 and enter into the bore on the other side. After installing the second

sleeve 5 the ends of the pin 3 bend.

Thus, the possibility of locking the nut on the threaded rod under conditions of limited access is achieved, since the pin can be inserted into the combined

the groove on the rod and diametrically slotted in the nut from the end of the threaded connection and fixed with sleeves when accessing one face of the nut.
