Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The embodiment is as follows:

referring to fig. 1-4, the utility model provides a high-pressure oil pipe sleeve, including overcoat 1, inner tube 2 and slip section of thick bamboo piece 3, fixed mounting inner tube 2 on overcoat 1 is equipped with the internal thread on the inner wall of overcoat 1, leaves the interval between internal thread and the inner tube 2, the inboard slidable mounting slip section of thick bamboo piece 3 of inner tube 2, and the body of slip section of thick bamboo piece 3 runs through and sets up movable through groove 6, the inboard movable mounting operating tube 7 of slip section of thick bamboo piece 3.

Specifically, as shown in fig. 3 and 4, the inner tube 2 is symmetrically provided with sliding grooves 4, the outer side of the sliding tube 3 is symmetrically provided with sliding strips 5, and the sliding grooves 4 are in sliding connection with the sliding strips 5, so that the drawing is convenient.

Specifically, as shown in fig. 1, the sliding cylindrical member 3 is provided with a screw hole, so that the sliding cylindrical member 3 can be easily pulled out.

Specifically, the length of the operating pipe 7 is smaller than the opening height of the movable through groove 6, so that the operating pipe 7 is prevented from being clamped when rotating.

The working principle is as follows:

a groove is arranged at the end part of the shaft part, and the size of the groove is matched with that of the inner pipe 2;

during installation, the sliding barrel part 3 is pushed out of the inner pipe 2 in a sliding mode, the operating pipe 7 is turned out, the sliding barrel part 3 is pushed into the inner pipe 2 in a sliding mode until the operating pipe 7 is clamped on the inner pipe 2, a long rod penetrates through the operating pipe 7, the operating pipe 7 is rotated, the whole sleeve can be operated, installed and fixed, the long rod is taken down, the sliding barrel part 3 is pulled outwards, the operating pipe 7 is placed back in a rotating mode, and then the sliding barrel part 3 is pushed back into the inner pipe 2 in a sliding mode;

when the sleeve is disassembled, a screw is slightly screwed into the screw hole of the sliding barrel part 3, the sliding barrel part 3 is drawn out by the screw, the operating pipe 7 is screwed out, and the whole sleeve is rotationally disassembled as above.
