Description
Technical field
The utility model relates to machinery fields, more particularly, to a kind of pipe joint with the connection of H-type taper.
Background technique
Casting concrete is needed using tremie in drilled pile, and existing pipe joint is cylinder, simultaneously
Sealing ring is set on connecting end surface, the extruding sealing ring of long-term big pressure, so that sealing ring rapid wear, reduces the longevity of connector
Life, while vertical connection, there are gaps between plug and conduit connecting pin, so that connection is unreliable, it is easily mobile.
Utility model content
The purpose of the utility model is to provide a kind of pipe joints with the connection of H-type taper, pour for connecting depth
Pipeline, not easily shifted, connection is reliable, and sealing ring is not easy to damage, and prolongs the service life.
To achieve the above object, the utility model provides a kind of pipe joint with the connection of H-type taper, including tapered
Plug, conduit connecting pin and fastening nut, the tapered plug upper half are cylindrical type, and the tapered plug lower half is cone
Type is provided with positioning ring between the upper half and the lower half, seal groove is provided on the outer wall of the lower half, described
Sealing ring is provided in seal groove, conduit connecting pin inner wall is trumpet type, and the fastening nut is socketed on described tapered slotting
The outside of head and the conduit connecting pin.
Preferably, the fastening nut and the positioning ring relative position are provided with fastener hole.
Preferably, the upper half outer wall of the tapered plug and the outer wall of the conduit connecting pin are provided with spiral shell
Line.
Preferably, the seal groove is annular groove, and the sealing ring is O-shaped silica gel sealing ring.
Preferably, height of the lower half height of the tapered plug not higher than the trumpet type part of the conduit connecting pin
Degree.
Therefore, a kind of pipe joint with the connection of H-type taper of the utility model using the above structure, for connecting depth
Degree pours pipeline, not easily shifted, and connection is reliable, and sealing ring is not easy to damage, and prolongs the service life.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Specific embodiment
Embodiment
Fig. 1 is a kind of pipe joint structural schematic diagram with the connection of H-type taper of the utility model, and Fig. 2 is conventional catheters
Joint structure schematic diagram, as shown in Figs. 1-2, it is a kind of with H-type taper connection pipe joint include tapered plug 1, conduit connect
Connect end 3 and fastening nut 4.
Tapered 1 upper half of plug be cylindrical type, tapered 1 lower half of plug be it is tapered, be arranged between the upper half and lower half
There is positioning ring 12, seal groove 11 is provided on the outer wall of lower half, sealing ring 2, the present embodiment sealing are provided in seal groove 11
Slot 11 is annular groove, and sealing ring 2 is O-shaped silica gel sealing ring.O-shaped silica gel sealing ring is set in the annular groove when installation,
The extruding force for reducing O-shaped silica gel sealing ring extends the service life of O-shaped silica gel sealing ring.By the insertion conduit connection of tapered plug 1
In end 3, there is no gap between tapered plug 1 and conduit connecting pin 3, so that connection is relatively reliable.3 inner wall of conduit connecting pin is loudspeaker
Type, the upper half outer wall of tapered plug 1 and the outer wall of conduit connecting pin 3 are provided with screw thread.The lower half of tapered plug 1 is high
For degree not higher than the height of the trumpet type part of conduit connecting pin 3, preventing tapered plug 1 from withstanding conduit connecting pin 3 leads to positioning not
Reliably, while the abrasion of conduit connecting pin 3 is reduced.Positioning ring 12 move up and down tapered plug 1 will not, then pass through fastening spiral shell
Mother 4 fastens.Fastening nut 4 is socketed on tapered plug 1 and connects with the outside screw of conduit connecting pin 3.Fastening nut 4 and positioning ring
12 relative positions are provided with fastener hole 41, and when bond diameter is excessive, for convenience of in installing and reaching pre-fastening moment, fastener hole 41 is used
Fixed fastening tool when installation pushes fastening tool rotation installation, so that installation is more laborsaving.
Therefore, a kind of pipe joint with the connection of H-type taper of the utility model using the above structure, for connecting depth
Degree pours pipeline, not easily shifted, and connection is reliable, and sealing ring 2 is not easy to damage, and prolongs the service life.
It is specific embodiment of the present utility model above, but the protection scope of the utility model should not be limited to thoses mentioned above.Appoint
What those skilled in the art is in the technical scope disclosed by the utility model, and any changes or substitutions that can be easily thought of,
It should be covered within the scope of the utility model, therefore the protection scope of the utility model should be limited with claims
Subject to fixed protection scope.
