Specific implementation mode
The technology of the present invention is described further below：
As shown in Figures 1 to 3, the anti-rotational piecing devices of a kind of lube oil cooler, including：Copper pipe 1, gasket seal 2, four directions
Shape limited block 3, oil tank bottom plate 4, round nut 5 and connector 6；1 lower end of the copper pipe is plugged in the through-hole of 6 upper surface of connector and full
Weldering connection, 1 lower face of copper pipe are bonded with 6 upper surface of connector, and 6 upper end surrounding of connector is cased with square limited block 3, the connector 6
Upper end is arranged on 4 upper surface of oil tank bottom plate, and 6 lower end of connector is inserted in the circular through hole being arranged concentrically with oil tank bottom plate 4；It connects
Gasket seal 2 is placed between first 6 and oil tank bottom plate 4；Round nut 5 is threaded on the screw thread of connector 6.
The whole connector 6 is in hollow T-shaped structure, and upper end is cube structure, and 6 upper surface centre of connector is provided with
Circular through hole；
6 lower end of the connector is cylindrical structure, and outer surface is provided with screw thread, the setting of 6 top and bottom junction of connector
There is round boss structure.
The whole square limited block 3 is in frame-shaped construction, and 3 center of square limited block is provided with square groove, rectangular
Groove size and the cube structure of 6 upper end of connector coordinate.
The circular through hole aperture of the oil tank bottom plate 4 is matched with the lower end outer diameter of connector 6, on the oil tank bottom plate 4
