Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Referring to fig. 1 to 2, the embodiment discloses a three-way pipe connecting member, including a connecting body 1, three spliced pole 2 is equipped with on the connecting body 1, two liang of different faces of three spliced pole 2, every spliced pole 2 appearance is rectangle post or circular post, spliced pole 2 is the hollow post that open at the center has the perforation, be used for penetrating bolt 3 in the perforation, the one end that the spliced pole 2 kept away from the connecting body 1 is terminal, the end of spliced pole 2 is equipped with inflation piece 4, inflation piece 4 comprises a plurality of inflation pieces 5 along the terminal circumference equipartition of spliced pole 2, 5 head ends of inflation pieces are connected with spliced pole 2 end through the elastic component, the elastic component can be designed to the shell fragment structure that the wall thickness is very thin, in order to satisfy the expansion of inflation piece 5 or the demand of contracting. In a natural state, the shape of the expansion piece 4 is matched with that of the connecting column 2; the pole portion of bolt 3 is worn out outside the terminal of spliced pole 2 and with 6 threaded connection of inflation core, and 6 lateral walls of inflation core comprise a plurality of outer wall 7 of slopes, and the outer wall 7 of a plurality of slopes of inflation core 6 is the inclined plane of head end shrink inwards, and the outer wall 7 of a plurality of slopes of inflation core 6 is the inclined plane cooperation with the inside wall face one-to-one of a plurality of inflation pieces 5.

The expansion piece 4 is composed of four expansion blocks 5 uniformly distributed along the circumferential direction of the tail end of the connecting column 2, and correspondingly, the outer side wall of the expansion core 6 is composed of four inclined outer wall surfaces 7.

The connecting body 1 is a cube, the three connecting columns 2 are respectively arranged on three adjacent surfaces of the connecting body 1, and the surface of the connecting body 1, on which the connecting columns 2 are arranged, is an installation surface.

Three mounting surfaces of the connecting body 1 are respectively provided with a step hole penetrating through the connecting body 1, the small head end of the step hole is arranged close to the mounting surface, and the step surface of the step hole is used for limiting the head of the bolt 3.

Three surfaces opposite to the three mounting surfaces on the connecting body 1 are three operation surfaces 8, and the large end of the stepped hole is blocked on the operation surfaces 8 through a blocking piece 9. The heads of the bolts 3 are covered, so that the consistency of the appearance of the connecting body 1 is ensured.

The bolt 3 adopts the hexagon socket head cap screw 3, is convenient for use with the cooperation of hexagon socket head cap spanner 10, easy to assemble and the operation of dismantling.

When the coupling post 2 is a circular post in shape, the tee coupling member is used to couple circular pipes.
