Detailed Description
As shown in fig. 1 to 3, a metal buckling-pressing type connecting assembly for connecting a pipe body comprises a lining metal connecting piece 1, a reinforcing sleeve 2, a buckling-pressing locking sleeve 3 and a connecting sleeve 4. To ensure a certain strength, the lining metal connector 1, the reinforcing sleeve 2, the crimping locking sleeve 3 and the connecting sleeve 4 may be made of stainless steel (e.g. martensitic stainless steel) or other steel materials. The end parts of the two pipe bodies 5 to be connected are processed into horn-shaped structures 6. The lining metal connecting piece 1 is a double-conical-surface tubular structure with small outer diameters at two ends and large outer diameter at the middle part, as shown in fig. 2. The inner surface of the lining metal connecting piece 1 is smooth, so that the resistance of fluid flowing through is reduced during pipeline transportation; the outer surface is processed with sealed tongue and groove 7, and sealed tongue and groove 7 is formed by processing a plurality of groove rings 11 on the inside lining metal connecting piece surface, and the axial lead of groove ring 11 and the axial lead of inside lining metal connecting piece 1 coincide, and each groove ring is arranged along the axial lead extending direction of inside lining metal connecting piece. Inside lining metal connecting piece 1's surface can laminate with loudspeaker column structure 6's internal surface, takes place certain extrusion deformation when loudspeaker column structure 6 compresses tightly sealed tongue and groove 7, plays fine sealed effect, prevents that the fluid from oozing from body and inside lining metal connecting piece 1 seam crossing. The exterior of the trumpet-like structure 6 is fitted with a reinforcing sleeve 2. One section of the reinforcing sleeve 2 is coated with the horn-shaped structure 6, and the other section is coated on the pipe body 5. The inner surface of one section of the reinforcing sleeve 2 which covers the pipe body is provided with anti-skid inverted teeth 12. The connecting sleeve 4 covers the connecting part of the end parts of the two pipes to be connected, internal threads are processed on the inner surface of the connecting sleeve, and in order to improve the convenience in installation, the cross section of the outer surface of the connecting sleeve is of a hexagonal structure, so that the spanner is convenient to exert force. Withhold locking sleeve 3 suit in the outside of strengthening sleeve 2, contain cylindrical sleeve section 8 and hexagonal sleeve section 9, cylindrical sleeve section 8 and hexagonal sleeve section 9 structure as an organic whole. The surface processing of cylindrical sleeve section 8 has positive and negative external screw thread to make withhold locking sleeve can be through screw-thread fit in connecting sleeve 4, and the internal surface of cylindrical sleeve section 8 is conical surface 10, and the cooperation of withholding locking sleeve 3 makes conical surface 10 sticiss on reinforcement sleeve 2 when connecting sleeve 4.
When in connection, the horn-shaped structure 6 at the end part of the pipe body 5 to be connected at one side is firstly attached to the outer surface of the lining metal connecting piece 1; then sleeving the reinforcing sleeve 2 on the end part of the pipe body 5, so that the reinforcing sleeve 2 is attached to one section of the pipe body and one section of the horn-shaped structure 6; one section of the reinforcing sleeve 2 covering the pipe body is pressed by a press machine to enable the reinforcing sleeve to tightly hold the pipe body, and the anti-skid inverted teeth 12 tightly hold the pipe body; sleeving the buckling locking sleeve 3 on the reinforcing sleeve 2 to enable the conical surface 10 to be attached to the reinforcing sleeve; then the connecting sleeve 4 is screwed on the buckling locking sleeve 3; similarly, respectively sleeving a reinforcing sleeve 2 and a buckling locking sleeve 3 on the pipe body 5 to be connected on the other side, tightly pressing the reinforcing sleeve to tightly hold the pipe body, tightly attaching a horn-shaped structure 6 of the pipe body 5 to be connected to the outer surface of the other side of the lining metal connecting piece 1, and screwing the buckling locking sleeve 3 into the connecting sleeve 4; along with the withholding of both sides locks the sleeve 3 and screws up, conical surface 10 compresses tightly gradually and consolidates the sleeve, and then makes 6 compresses tightly inside lining metal connecting piece 1 of tubaeform structure, and 6 internal surface pressings of tubaeform structure are sealed tongue and groove 7 and are taken place certain extrusion deformation, play fine sealed effect, prevent that the fluid from oozing from body and 1 seam crossing of inside lining metal connecting piece. When the pipe body is greatly deformed after long-time use or expansion with heat and contraction with cold, the buckling and locking sleeves 3 on the two sides can be continuously screwed, the pressing force of the horn-shaped structure 6 and the lining metal connecting piece 1 is increased, and the long-time sealing performance and the tensile resistance are ensured.
