SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is that the surface of the joint is easily polluted and damaged when the existing stainless steel oil pipe joint device is used for a long time; and the hydraulic pressure is very easy to be infected with impurities to block the pipeline in the transportation process.

In order to solve the technical problem, the utility model discloses a technical scheme be:

the stainless steel oil pipe joint device comprises a first joint and a second joint, wherein the end face of the first joint is fixedly connected with an outer shell, a gasket is arranged on the outer side wall of an external thread column of the outer shell, the end face, far away from the first joint, of the outer shell is fixedly connected with an external thread column, the external thread column is in threaded connection with the internal thread column by arranging the outer shell, the connecting position of the internal thread column and the external thread column is protected by the outer shell, a filter screen plate is fixed by the external thread column and the internal thread column, passing hydraulic oil is filtered, and then the gasket is fixed by the internal thread column and the outer shell to prevent the hydraulic oil from leaking and improve the sealing performance of the device;

the end face of the second connecting head is fixedly connected with an internal thread column, and a filter screen plate is arranged between the external thread column and the outer shell.

Preferably, the internal threaded column is in threaded connection with the external threaded column, so that the first connector and the second connector are fixed.

Preferably, the gasket is located at the position of the end face of the internally threaded column, and the device is prevented from leaking through the gasket.

Preferably, the filter screen plate is positioned at the end face of the external thread column.

Preferably, the filter screen plate consists of a rubber plate and a filter screen arranged in the rubber plate.

Preferably, the first connector and the second connector are arranged in a circular truncated cone shape.

The utility model has the advantages as follows:

the utility model provides a stainless steel oil pipe joint device, through setting up the shell body for the internal thread post carries out threaded connection with the external screw thread post, through the hookup location of shell body protection internal thread post and external screw thread post, fixes the filter plate board through external screw thread post and internal thread post, filters the hydraulic oil of process, fixes the gasket through internal thread post and shell body afterwards, prevents that hydraulic oil from spilling, hoisting device's seal.
