In a preferred embodiment, described hydraulic pressure joint pilot hole and/or described electronics joint pilot hole are set for the eccentric.
In a preferred embodiment, the outer wall connecing end in described hydraulic pressure joint shutoff joint axially offers sealed groove.
In a preferred embodiment, the outer wall of the external connection end of described hydraulic pressure joint shutoff joint axially offers sealed groove.
In a preferred embodiment, be stepped hole in the endoporus of described external connection end, described electric combination hub is fixedly connected with the step place of described stepped hole.
In a preferred embodiment, also comprise, electric combination hub sealing mat; On described electric combination hub and described stepped hole correspondence position, offer groove at the inwall of described stepped hole, described electric combination hub sealing mat is fixedly connected with described groove, assembling sealing ring in described groove.
In a preferred embodiment, also comprise, electric plug sealing mat; Save on the correspondence position on the endoporus of pilot hole at described electric plug and described electronics, offer groove at the inwall of described endoporus, described electric plug sealing mat is fixedly connected with this groove, assembling sealing ring in described groove.
In a preferred embodiment, the endoporus of described electronics joint pilot hole is that chamfering is connected with exit orifice.
In a preferred embodiment, the edge of opening of the exit orifice of described electronics joint pilot hole comprises chamfering.
In a preferred embodiment, described hydraulic pressure joint shutoff joint is stainless steel material.
Therefore compared with prior art, save with electronics the adapter assembly be connected according to drilling hydraulic joint provided by the utility model to have the following advantages: the joint that the utility model proposes, relative to the form of end face seal, the utility model adopts twice radial seal, ensure that the reliability of sealing, ensure that the convenience of electrical connection, reliable.
Accompanying drawing explanation
Fig. 1 is in a kind of embodiment of the present utility model, and drilling hydraulic joint and electronics save the composition schematic diagram of the adapter assembly joint be connected.
Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described in further detail.
In a kind of preferred embodiment of the present utility model, drilling hydraulic joint saves with electronics the adapter assembly be connected, and comprising: hydraulic pressure joint shutoff joint 10, electric plug 20 and electric combination hub 30.The link end face of hydraulic pressure joint comprises the hydraulic pressure joint pilot hole 40 offered vertically.Connect end 11 in hydraulic pressure joint shutoff joint 10 to save pilot hole 40 with hydraulic pressure and be fixedly connected with, external connection end 12 stretches out the end face that hydraulic pressure saves link.Electric combination hub 30 is fixed in the endoporus of external connection end 12.The end face of electronics joint link offers electronics joint pilot hole 50 vertically.Fix electric plug 20 in the endoporus of electronics joint pilot hole 50, exit orifice is corresponding to external part, is tightly connected with external part, thus electric plug 20 is electrically connected with electric combination hub 30.For ease of from axially installing, above-mentioned
Hydraulic pressure joint pilot hole 40 and/or electronics joint pilot hole 50 are set for the eccentric.Hydraulic pressure joint shutoff joint 10 is stainless steel material.
More tight for making hydraulic pressure save the sealing saving shutoff joint 10 with hydraulic pressure, in a kind of embodiment of the present utility model, as shown in Figure 1, the outer wall connecing end 11 in hydraulic pressure joint shutoff joint 10 axially offers sealed groove 13.Axially sealed groove 14 is offered at the outer wall of the external connection end 12 of hydraulic pressure joint shutoff joint 10.And in above-mentioned groove, assemble O RunddichtringO, to ensure better sealing effectiveness.
