The invention relates to a door-plate processing apparatus and particularly relates to an internal pipe for a building wall. The internal pipe comprises an installing seat made of rubber and a woody installing cover, wherein the installing seat comprises an upper conical platform and a lower support which are integrally formed; a ring-shaped groove is arranged at the connecting position of the lower support and the upper conical platform; an upper opened groove and a lower opened groove are formed in the installing seat, are communicated and are coaxial; the aperture of the upper opened groove is consistent to the outer diameter of a nail head; the aperture of the lower opened groove is consistent to the outer diameter of a nail rod; the upper end surface of the upper conical platform is provided with a spring cushion; the lower end of the inner side surface of the installing cover is provided with an inner inclined surface which has consistent slope and corresponding position with the outer conical surface of the upper conical platform; and the middle part of the inner side surface of the installing cover is provided with an inner ring groove for containing the upper conical platform. The internal pipe has the advantages that the defect of exposure of the existing nail head is overcome and the nail head can be shielded.
