The arc notch 2 is recessed towards the inside of the body from the lower wall of the body 1, the body is penetrated in the thickness direction of the body 1, the cross section is arc-shaped, the central axis of the arc notch 2 is a straight line passing through an O point in the figure 2 and perpendicular to the paper surface, and an included angle from two end points of the arc-shaped cross section to the central axis is a central angle A of the arc notch 2. The butt joint auxiliary part only plays an auxiliary role in the installation process of the wire outlet device pressure equalizing pipe, and needs to be taken down after the auxiliary is completed, and in order to be taken down, the central angle A of the arc notch 2 is not more than 180 degrees. The arc bulge 3 extends from the front wall surface of the body 1 to the outside in a vertical mode, is a part of a cylinder, has a circular ring-shaped cross section, is a straight line passing through a point O in a graph 2 and perpendicular to the paper surface, and is collinear with the central axis of the arc notch 2 and the arc bulge 3. The front wall surface of the body 1 is the surface of the body 1 facing the reader in fig. 2, and is one of the planes with the largest area of the body 1. The body 1 is provided with a blocking part 4, the blocking part 4 is arranged on the outer side of the arc protrusion part 3, the arc notch 2 is arranged on the inner side of the arc protrusion part 3, and the arc notch 2 and the blocking part 4 are respectively arranged on the inner side and the outer side of the arc protrusion part 3.
The body 1 is provided with three mounting holes 11 which are communicated in the thickness direction, when the butt joint auxiliary part is mounted or dismounted, fingers can stretch into the mounting holes 11, so that mounting personnel can grab the butt joint auxiliary part conveniently, the mounting personnel can apply force conveniently, and the mounting and dismounting are convenient and labor-saving. The body 1 is equipped with two lug parts 5, and lug part 5 is from the radial outside protrusion of the outward flange edge circular arc breach 2 of body 1, in the outside of circular arc bulge 3 and barrier portion 4. After the butt joint auxiliary part is installed on the lifting seat iron cylinder (see fig. 4 and 5), the lug parts 5 are arranged outside the lifting seat iron cylinder, so that when the butt joint auxiliary part is detached, force is applied to the butt joint auxiliary part from the outside of the lifting seat iron cylinder, and the detachment is more convenient and more labor-saving.
Referring to fig. 4 and 5, the method for butting the butting auxiliary member of the equalizing pipe of the wire outlet device comprises the following steps.
