Detailed description of the invention
The structural representation of the hydraulic pipeline connecting device that Fig. 1 provides for the embodiment of the present invention；Fig. 2 is this
The front view of the connector that inventive embodiments provides；Fig. 3 is the left view of connector shown in Fig. 2.
As Figure 1-3, the hydraulic pipeline connecting device that the present embodiment provides, including pressure input adapter
1, pressure out splice going splice 2 and connector 3.
There is in pressure input adapter 1 the first horizontal cylinder cavity 11, pressure input adapter 1 has
Longitudinal slot 12；Pressure out splice going splice 2 is embedded in the first cylinder cavity 11, pressure out splice going splice 2
The second cylinder cavity 21 that interior tool is horizontal, the outer wall of pressure out splice going splice 21 has annular groove 22.
Specifically, the outline of pressure input adapter 1 can be cylindrical structure, outside pressure out splice going splice 2
Profile can also be cylindrical structure, and the first cylinder cavity 11 can be straight wall cylindrical cavity, it is also possible to for rank
Ladder cylindrical cavity, accordingly, the outline of pressure out splice going splice 2 can be straight wall cylindrical structure, it is possible to
Think stepped cylindrical body structure.The outer wall of pressure out splice going splice 2 and the inwall of the first cylinder cavity 11 match
Closing, pressure out splice going splice 2 can slide in the first cylinder cavity 11.
As shown in Figures 2 and 3, connector 3 can be U-shaped structure, and the side of connector 3 has circular arc
Shape draw-in groove 31；In connector 3 is plugged in the slot 12 of pressure input adapter 1 and be fastened on pressure output
In the annular groove 22 of joint 2；The diameter of circular arc draw-in groove 31 is more than the external diameter of pressure out splice going splice 2.
Specifically, connector 3 can be U-shaped sheet, and be arranged on U-shaped sheet two stretch circular arc draw-in groove 31
Go out on arm.Between circular arc draw-in groove 31 and two cantilever arms of U-shaped sheet, space forms circular space, is used for
Card sets pressure out splice going splice 2.The width of the annular groove 22 of pressure out splice going splice 2 is more than connector 3
Thickness, so that connector 3 can be fastened in annular groove 22, and can guarantee that pressure out splice going splice
Can axially slide relative to connector 3 in 2.
The hydraulic pipeline connecting device that the present embodiment provides in actual applications, is used for being connected to hydraulic system
Line connection, pressure input adapter 1 is connected with the pressure input of fluid pressure line, pressure output connect
2 are connected with the pressure output end of fluid pressure line, and the highly pressurised liquid in fluid pressure line is from pressure input adapter
The first cylinder cavity 11 of 1 enters, and the second cylinder cavity 21 of hydraulic pressure out splice going splice 2 of going forward side by side exports,
This hydraulic pipeline connecting device can realize the connection to an even fluid pressure line.
As it is shown in figure 1, when the highly pressurised liquid in fluid pressure line leads to from the first cylinder of pressure input adapter 1
When chamber 11 enters, highly pressurised liquid acts on the end face of pressure out splice going splice 2 so that pressure out splice going splice
2 move right, and pressure out splice going splice 2 is embedded in the circular arc draw-in groove 31 of connector 3, therefore, when
When hydraulic system is in duty with pressure, circular arc draw-in groove 31 and the pressure out splice going splice 2 of connector 3
Being in fastening state, by connector 3 locking, will not be extracted easily, the vibration of machinery itself simultaneously is also
Connector 3 will not be made to come off, highly pressurised liquid moment can be avoided to flow out and hurt sb.'s feelings, reduce potential safety hazard.
When after the liquid pressure release in liquid line, can manually promote pressure out splice going splice 2 to left movement,
So that pressure out splice going splice 2 from the circular arc draw-in groove 31 of connector 3 from abjection, at this point it is possible to will
Connector 3 is extracted from the slot 12 of pressure discrepancy joint 1, convenient dismounting fluid pressure line.
On the basis of the hydraulic pipeline connecting device technical scheme that above-described embodiment provides, further, the
It is provided with sealing ring 4 between one cylinder cavity 11 inwall and the outer wall of pressure out splice going splice 2.Can improve
This hydraulic pipeline connecting device sealing.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, rather than right
It limits；Although the present invention being described in detail with reference to foregoing embodiments, this area common
Skilled artisans appreciate that the technical scheme described in foregoing embodiments still can be modified by it,
Or the most some or all of technical characteristic is carried out equivalent；And these amendments or replacement, and
The essence not making appropriate technical solution departs from the scope of various embodiments of the present invention technical scheme.
