Specific embodiment
It elaborates with reference to the accompanying drawing to specific embodiment of the present utility model.
As shown in Figure 1-Figure 3, a kind of telescopic joint convenient for fixing with dismantling includes shell 1, central spindle 2 and locking nut 3；Institute
Stating central spindle 2 is hollow circular tube, the central spindle 2 and 1 grafting of shell；Screw thread, the shell are provided on the locking nut 3
1 includes fixing end 11 and inserted terminal 12, and connecting column 15 is arranged on the inserted terminal 12, is provided with spiral shell on the side wall of the connecting column 15
Hole 16 is provided with the internal screw thread to match with the locking nut 3, the locking nut 3 and the screw hole on the screw hole 16
16 are threadedly coupled；Threaded connection can make connection it is more firm, will not because of external force influence and burst apart out.The locking screw
Mother 3 includes nut cap 31 and nut cylinder 32, is provided with rotating gravure 23, the nut cylinder 32 on the outer wall of the central spindle 2
Bottom end be plugged in the rotating gravure 23.
Further, the width of the rotating gravure 23 is equal to the outer diameter of 32 bottom end of nut cylinder, herein nut cylinder 32
Bottom end and rotating gravure 23 exactly match, the two with the use of can reach two effects: one, after fixed good position, outside
Under the impact of power, because there is the dual restriction of the rotating gravure 23 and locking nut 3, therefore connection will not be made to burst apart out；Two, institute
State rotating gravure 23 rotates how many distance, the nut cylinder 32 can may be implemented any with 23 perfect matching of rotating gravure
The adjusting of small compensation rate, use are more convenient.
Further, the internal diameter of the fixing end 11 is equal to the internal diameter of the central spindle 2, and the internal diameter of the inserted terminal 12 is equal to
The outer diameter of the central spindle 2；At its internal diameter variation, as the maximum value of compensation rate adjusting, this setting can slow down hydraulic pressure to pipe
It is damaged caused by wall.
Further, connector 1, the fixation are provided at port of the fixing end 11 far from the inserted terminal 12
Shell fixed column 14 is additionally provided on end 11, the section of the shell fixed column 14 is in regular hexagon；When connection too fastens,
It can use the light instruments such as spanner occlusion shell fixed column 14 to disassemble shell 1.
Further, one end far from the shell 1 of the central spindle 2 is provided with connector 2 21, also sets in the central spindle 2
It is equipped with central spindle fixed column 22, the section of the central spindle fixed column 22 is in regular hexagon；When connection too fastens, it can use and pull
The light instruments such as hand occlusion central spindle fixed column 22 disassembles central spindle 2.
Further, the shell 1, central spindle 2 and locking nut are made of 304 stainless steels, can both bear certain
Pressure, also will not because of by fluid corrode or get rusty, can be used for a long time.
As shown in figure 4, connector one is passed through ready-packaged joint and pipeline first for the schematic diagram after the utility model assembling
One end connection, then crosses ready-packaged joint for connector two-way and connect with one end of other pipeline, sealing ring is inserted on the outside of central spindle, will
Sealing ring moves on to beside central spindle fixed column, and central spindle is inserted into shell, the distance of needs is gradually adjusted, when distance has adjusted
Finish, locking nut rotation is connected to bottom end and the rotating gravure perfection grafting for making its nut cylinder into screw hole, hereafter in pipeline
It is passed through liquid, normal use, because the outer diameter of central spindle and the internal diameter of inserted terminal are identical, therefore it seals, and secondly seals
The presence of circle can do further encapsulation process to telescopic joint, not will lead to leak.In use, if because external device (ED)
Needs the micro length of telescopic joint is adjusted, central spindle fixed column can be engaged by tools such as spanners and carry out micro rotation
It can be realized.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
