Embodiment Construction
[0026] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0027] Such as Figure 1-7 As shown, a quick-connect type axial connection assembly includes a male head 1 and a female head 2;
[0028] The tail of the female head 2 is provided with pull nails, the head of the female head is provided with a connecting part 21, and the side of the connecting part 21 is provided with a notch.
[0029] The connecting part 21 is provided with a cavity in which an expansion tube 22, a limiting ring 23, a spring 24 and a retaining ring 25 are sequentially arranged in the cavity; the right end of the retaining ring abuts against the left end of the cavity Top; The material of the expansion tube 22 is spring steel.

The invention discloses a quick-connecting axial connection assembly. The quick-connecting axial connection assembly comprises a male head and a female head, wherein a pull nail is arranged at the tail of the female head, a connection part is arranged at the head of the female head, an expansion pipe, a limitation ring, a spring and a baffle ring are sequentially arranged in the connection part, the expansion pipe comprises a tail annular part and a head sheet-shaped part, the tail of the sheet-shaped part is connected with the annular part, a through hole is formed in a middle part of the limitation ring, anti-slip thread is arranged on an outer surface of the tail of the male head, and a jacking rod is connected with the head of the male head. Compared with an existing connection mode, the device has the advantages of rapid connection speed and high connection strength; and under an effect of the spring, no gap can be generated between the male head and the female head even the quick-connecting axial connection assembly is used for a long time, and the stability of the whole mechanism can be ensured.
Description
Technical field [0001] The invention relates to a quick connection type axial connection assembly. Background technique [0002] At present, the existing shield tunnels are generally formed by splicing several prefabricated segments. When this type of segment is prefabricated, it is necessary to locate the connecting bolt holes on the template in advance so that the prefabricated segments can be installed in the shield. In the tunnel, special connecting bolts are used for circular and longitudinal connection and assembly and fastening, thereby forming a complete concrete pipeline. However, it is necessary to solve the problem of circumferential and longitudinal splicing between segments in the specific use process. The present invention solves the problem of connection between adjacent segments in the longitudinal direction. The existing segment assembly has slow construction speed and labor intensity. Large, the connection strength is not high, the shear resistance is not stron...
