Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The first embodiment,

The structure of the quick coupling for oil transporting pipes of the present embodiment, as shown in fig. 1 to 6, includes: male head 1 and female head 2;

the outer circumference of the contact end of the male head 1 and the female head 2 is provided with an outer inclined surface 12, the inner circumference of the contact end of the female head 2 and the male head 1 is provided with an inner inclined surface 25, the outer inclined surface 12 and the inner inclined surface 25 have the same taper, and after the male head 1 and the female head 2 are spliced, the outer inclined surface 12 and the inner inclined surface 25 are mutually attached, so that oil can be effectively prevented from leaking from the joint of the male head 1 and the female head 2;

the male head 1 is provided with a snap ring 11; a support lug 21 is arranged on the female head 2, a bolt 22 is arranged on the support lug 21, a connecting rod 24 is arranged at the outer end of the bolt 22, a spring 23 is sleeved on the connecting rod 24, and a pull ring 241 is arranged at the outer end of the connecting rod 24;

spring 23 can push bolt 22 to slide on support lug 21, and when male head 1 is inserted into female head 2, male head 1 can push bolt 22 to slide reversely on support lug 21;

when the male head 1 is inserted into the female head 2, the male head 1 extrudes the lock tongue 22, the lock tongue 22 is contracted in the support lug 21, when the male head 1 is inserted into the female head 2 to a position where the snap ring 11 corresponds to the lock tongue 22, the male head 1 does not extrude the lock tongue 22, the lock tongue 22 enters the snap ring 11 under the pushing of the spring 23, and the connection between the male head 1 and the female head 2 is completed;
