Abstract

The utility model relates to a fast interface of a mould-pipe, belonging to a fast interface structure to integrate a pipe line by connecting mould-pipes. A groove at the inside faucet of the mould-pipe is embedded with a gum ring for sealing. A faucet of another mould-pipe is inserted into the pipe socket of the former mould-pipe. The gum ring is pressed tightly between the pipe socket and the faucet of the mould-pipes. A differential is sleeved outside the joint of the pipe socket and the faucet of the mould-pipes. Axial bolt points are distributed uniformly on the differential. The inside of the differential is arranged with a shoulder, which is propped up the gum ring. Inside the bolt points of the differential hook bolts are arranged. The hooks of the bolts hook the outer edge of the pipe socket. The differential can be fixed on the pipe socket by screwing the nuts of the hook bolts tightly. The utility model has the advantages of being simple in structure, easy in processing and manufacture, convenient and instant in construction, etc.

Description

The cast tube fast interface

(1), technical field

The utility model belongs to a kind of fast interface structure that connects into pipeline with cast tube.

(2), background technique

At present, when cast tube connects into pipeline, in the bellmouth inner groovy of cast tube, put into the rubber ring that is used for sealing, the socket of another root cast tube inserts in the bellmouth of described cast tube, rubber ring tightly is squeezed between the bellmouth and socket of cast tube, realizes sealing and anti-slip with this.But cast tube can only be constructed when being linked and packed one by one, and efficient is low, and the pipe laying ditch width that need dig is big, wastes time and energy, and is long in time limit.

(3), summary of the invention:

In order to overcome the shortcoming of prior art, the utility model provides a kind of cast tube fast interface, and it is simple in structure, convenient and quick construction, efficient height.

The technical scheme in the invention for solving the technical problem is: be embedded with the rubber ring that is used for sealing in the inner groovy of cast tube bellmouth, the socket of another root cast tube is inserted in the bellmouth of described cast tube, rubber ring tightly is squeezed between the bellmouth and socket of cast tube, be with differential outside the bellmouth of described cast tube and the socket joint, uniform axial bolt hole on the differential, there is convex shoulder the inboard of differential, convex shoulder withstands on the described rubber ring, in the bolt hole of described differential HOOK BOLTS is housed, the eave tile of HOOK BOLTS catches on the outer of bellmouth, screw the nut of HOOK BOLTS, differential can be fixed on the bellmouth.

Since adopt differential and HOOK BOLTS, thus simple in structure, easily manufacturing, convenient and quick construction, efficient height.

(4), description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is the utility model partial sectional view.

(5), embodiment

Be embedded with the rubber ring 7 that is used for sealing in the inner groovy of cast tube bellmouth 8, the socket 1 of another root cast tube is inserted in the bellmouth 8 of described cast tube, rubber ring 7 tightly is squeezed between the bellmouth 8 and socket 1 of cast tube, as shown in drawings.Be with differential 4 outside the bellmouth 8 of described cast tube and socket 1 joint, uniform axial bolt hole on the differential 4, there is convex shoulder 9 inboard of differential 4, and convex shoulder 9 withstands on the described rubber ring 7.HOOK BOLTS 3 is housed in the bolt hole of described differential 4, and the eave tile 6 of HOOK BOLTS 3 catches on the outer 5 of bellmouth 8.Screw the nut 2 of HOOK BOLTS 3, differential 4 can be fixed on the bellmouth 8.For antirust, described differential 4 and HOOK BOLTS 3 adopt the stainless steel manufacturing.

Claims

1, a kind of cast tube fast interface, in the inner groovy of cast tube bellmouth (8), be embedded with the rubber ring 7 that is used for sealing, the socket of another root cast tube (1) is inserted in the bellmouth (8) of described cast tube, rubber ring (7) tightly is squeezed between the bellmouth (8) and socket (1) of cast tube, it is characterized in that: be with differential (4) outside bellmouth of described cast tube (8) and socket (1) joint, differential (4) is gone up uniform axial bolt hole, there is convex shoulder (9) inboard of differential (4), convex shoulder (9) withstands on the described rubber ring (7), HOOK BOLTS (3) is housed in the bolt hole of described differential (4), and the eave tile (6) of HOOK BOLTS (3) catches on the outer (5) of bellmouth (8).

2, fast interface according to claim 1 is characterized in that: the material of described differential (4) and HOOK BOLTS (3) is a stainless steel.
