1. A cleaning device for the inner and outer walls of a steel pipe comprises a main pipe body, wherein the rear end of the main pipe body is a liquid inlet end, the front end of the main pipe body is provided with a spray head which is coaxial with the axis, and the front end of the spray head is provided with a liquid outlet which can be communicated with the liquid inlet end to form a spray nozzle;

  • the middle part of the front end of the spray head is coaxially provided with a frustum body which protrudes forwards and the small-diameter end of which is forward, the peripheral position of the front end of the spray head is coaxially provided with a circle of annular sleeve body which extends forwards to the periphery of the frustum body, a circle of positioning groove which is only used for inserting the end part of the steel pipe to be cleaned and can be positioned on the frustum body is formed between the frustum body and the annular sleeve body in a clamping way, and the outer diameter of a ring formed by the intersection of the plane of the frustum body in a cross section circle vertical to the axial lead direction and the positioning groove, wherein the cross section circle is the same as the inner diameter of the steel pipe to be cleaned;

    an inner wall cleaning liquid outlet is formed in the middle of the front end of the frustum body, and a circle of outer wall cleaning liquid outlet is formed at the bottom of the positioning groove;

    when the device is used, after one end of the steel pipe to be cleaned is inserted into the positioning groove for positioning, the liquid can be discharged through the inner wall cleaning liquid outlet to clean the inner wall of the steel pipe, and meanwhile, the liquid can be discharged through the outer wall cleaning liquid outlet to clean the outer wall of the steel pipe;

    the inner cavity at the front end of the inner wall cleaning liquid outlet is in a frustum shape with a large diameter end facing outwards;

    an instant switch mechanism is also arranged in the main pipe body;

    the instant switch mechanism comprises the spray head and a switch spring, wherein the switch spring is positioned in a switch spring installation cavity communicated with the liquid inlet end, the rear end of the switch spring is abutted to the rear end of the switch spring installation cavity, the front end of the switch spring is connected with a spherical plug and enables the front end of the spherical plug to be abutted to the rear end of the spray head, and an inlet of a liquid channel where a liquid outlet is positioned on the spray head is positioned on the side surface of the spray head and can be exposed out of the switch spring installation cavity after the switch spring is compressed.
