The utility model provides an anti-falling clamping sleeve structure based on the fact that only nuts are needed to be loosened when pipelines are replaced in actual work, and a clamping sleeve group is not needed to be disassembled
As shown in fig. 1-3, in one embodiment of the present utility model, an anti-falling ferrule structure is provided, including: the connector comprises a connector body 1, a nut 2 and a clamping sleeve group, wherein the nut 2 is in threaded connection with the connector body 1, an axial gap is formed between the connector body 1 and the nut 2, and the clamping sleeve group is arranged in the axial gap; one side of the nut 2, which is far away from the end face of the connector body 1, is provided with a mounting ring 21, the mounting ring 21 is provided with a limiting piece, the limiting piece penetrates through the single-side annular wall of the mounting ring 21, and the distance from the inner end face of the screwed limiting piece to the axis of the connector body 1 is smaller than half of the major diameter of the external thread of the connector body 1.
When the nut 2 is used, the nut 2 and the connector body 1 are screwed up, then the limiting piece is arranged on the mounting ring 21, and the moving position of the nut 2 is limited by the limiting piece, so that the clamping sleeve is prevented from falling off. It will be appreciated of course that when changing the ferrule set, the stop member must be removed and the nut 2 loosened for replacement.
According to the nut 2 with the original clamping sleeve structure, the mounting ring 21 is extended, the limiting piece is arranged on the mounting ring 21, and after the limiting piece is screwed down, the bottommost surface of the limiting piece is lower than the outer diameter of the external thread, so that the loosening position of the nut 2 is limited, as shown in fig. 3, the clamping sleeve nut 2 is prevented from falling off, the problem that the nut 2 is not tightly connected with the connector body 1 before a pipeline 5 is not arranged in the clamping sleeve structure is solved, and the problem of loss of parts caused by the separation of the nut 2 is avoided.
In this embodiment, as shown in fig. 2, the external shape of the nut 2 is shown, the nut 2 includes a mounting ring 21, a rotating portion 22 and a stop ring 23 sequentially arranged from left to right, and the inner diameter of the mounting ring 21 is larger than the outer diameter of the external thread of the connector body 1, so that the mounting ring 21 can be sleeved on the rear side of the external thread of the connector body 1. The outer wall of the rotating part 22 is a regular hexagon so as to facilitate the rotation of the nut 2, an inner side surface is provided with an inner thread matched with the outer thread of the connector body 1, and the inner diameter of the baffle ring 23 is matched with the pipeline 5.
A threaded hole is provided in the mounting ring 21, the axis of which intersects the axis of the mounting ring 21, i.e. the threaded hole is arranged in the radial direction of the mounting ring 21 in order to achieve a limiting function of the axis.

The inner diameter of the right end of the first clamping sleeve 31 is provided with a second inner conical surface, and the second inner conical surface abuts against the first step of the second clamping sleeve 32. Meanwhile, the right end face of the second step abuts against the left side face of the nut 2 baffle ring 23.
Through the screw tightening force between the connector body 1 and the nut 2, the nut 2 snap ring applies a leftward acting force to the second clamping sleeve 32, the left end of the second clamping sleeve 32 is extruded on the second inner conical surface of the first clamping sleeve 31, so that the outer conical surface on the left side of the clamping sleeve is combined with the first inner conical surface of the connector body 1, and the inner edge uniformly bites into the pipeline 5 to form sealing.
When the nut 2 is loosened under the vibrating environment, the bottom surface of the limit screw 4 is lower than the outer diameter of the external thread, so that when the limit screw 4 moves to a certain position along with the nut 2, the limit screw 4 is in contact with the thread, the nut 2 can not move continuously, and the problem of part loss caused by the separation of the nut 2 is avoided. The line 5 is only pressed by 1.5 times the lead, and the replacement condition of the line 5 can be satisfied.
