The inner wall of the extension ring is a tapered wall, and the reinforcing sleeve is extended In the ring, the lower end of the reinforcement sleeve has an extension extending radially outward, the extension is inserted into the top of the tapered pipe, the outer wall of the extension is close to the top inner wall of the tapered pipe, and the top surface of the extension is pressed Leaning against the bottom end surface of the extension ring, the top of the reinforcing sleeve has a screw connection part, which protrudes from the top of the tapered pipe, and an annular end cover is screw connected to the screw connection part.

There is a raised reinforcing ring extending radially inward on the inner side wall of the middle part of the reinforcing sleeve, and there is a stepped hole on the annular end plate of the annular end cover. The head is inserted into the large diameter end of the stepped hole, and the bottom end of the positioning screw passes through the small diameter end of the stepped hole and is screwed into the threaded hole.

The outer wall of the reinforcing sleeve is in close contact with the inner wall of the extension ring.

The through holes are hexagonal through holes.

There is a groove on the outer wall of the middle part of the tapered pipe, the middle part of the groove has a mounting groove, and both sides of the mounting groove have positioning concave holes.

The outstanding effect of the present utility model is:

Compared with the prior art, it can strengthen the strength at the small-diameter end of the tapered pipe, guarantee normal processing, and have good processing effect.

detailed description:

Embodiment, see as shown in Fig. 1 to Fig. 3, a kind of tapered pipe device with hollow structure, comprises tapered pipe 10, and the upper part of described tapered pipe 10 is a small diameter end, and the lower part of tapered pipe 10 is At the large diameter end, a plurality of through holes 11 are formed on the upper side wall of the tapered pipe 10, the top inner wall of the tapered pipe 10 is a vertical wall, and the top inner wall of the top of the tapered pipe 10 has an inward radially extending The extension ring 12, the inner side wall of the extension ring 12 is a tapered wall surface, the reinforcement sleeve 20 is inserted into the extension ring 12, the lower end of the reinforcement sleeve 20 has an extension 21 extending radially outward, and the extension 21 is inserted into the cone In the top of the shaped tube 10, the outer sidewall of the extension part 21 is close to the top inner sidewall of the tapered tube 10, the top surface of the extension part 21 is pressed against the bottom end surface of the extension ring 12, and the top end of the reinforcing sleeve 20 has a screw joint. 22. The threaded portion 22 protrudes from the top end of the tapered tube 10, and the threaded portion 22 is threaded with an annular end cap 30.

Furthermore, the inner side wall of the middle part of the reinforcing sleeve 20 has a raised reinforcing ring 23 extending radially inward, and the annular end plate of the annular end cover 30 has a stepped hole 31, and the step hole 31 is directly below the reinforcing ring 23. The threaded holes 24 on the top are aligned, the head of the positioning screw 1 is inserted into the large diameter end of the stepped hole 31, and the bottom end of the positioning screw 1 passes through the small diameter end of the stepped hole 31 and is screwed into the threaded hole 24. middle.

Further speaking, the outer wall of the reinforcement sleeve 20 is in close contact with the inner wall of the extension ring 12 .

Furthermore, the through hole 11 is a hexagonal through hole.

Furthermore, the tapered pipe 10 has a groove 13 on the outer wall of the middle part, the middle part of the groove 13 has a mounting groove 14 , and both sides of the mounting groove 14 have positioning concave holes 15 .

In this embodiment, the strength at the small-diameter end of the top end of the tapered pipe 10 is increased by adding the reinforcing sleeve 20 and the annular end cap 30, which is convenient for processing and supporting.
