Description
Technical field
The utility model belongs to draining blowdown pipeline field, more particularly to the spiral bar liner transition of a kind of carat of pipe
Part.
Background technology
Currently, the heavy caliber pipe of domestic production --- HDPE enhances hollow spiral tube（Type B）, abbreviation carat pipe.Its
The head and end of liner bellows is all that the extrusion cladding material freely with its periphery combines in peripheral spiral bar, causes product should
Locate appearance warpage sometimes, stays sometimes, and also material is few sometimes for clad, material is more sometimes, so product has poor appearance, matter herein
The defect that amount is poor, intensity is not high and unstable, so, existing product herein suddenly wait improving by insufficient place.
Utility model content
This patent product is at least one defect overcome described in the above-mentioned prior art, provides the spiral bar of a kind of carat of pipe
Liner transition piece, it is simple in structure, novel which has many advantages, such as, dimensionally stable and production are quick, it is outer with carat pipe
After enclosing in muscle the connection use of liner bellows, the peripheral spiral bar head and end of carat pipe is smooth, appearance is good.
The technical solution of the utility model is：The spiral bar liner transition piece of a kind of carat of pipe, wherein including centrum, institute
It states the big one end of centrum bore and is equipped with socket, the socket is elastic socket, and the outer surface of the transition piece is equipped with staggeredly clearly demarcated
Blind slot, the transition piece are attached using the liner bellows of socket and the spiral bar head and end of carat pipe periphery.
The liner transition piece is made of cone and socket two parts；Its entire outer surface is equipped with staggeredly clearly demarcated blind slot, makes
The liner transition piece can be along the free bend of 360 degree of axis direction of rotation, and intensity is high；Its cone structure can be the outer of carat pipe
The liner bellows for enclosing spiral bar head and end distinguishes ascending and descending reasonable transition, utilizes socket and carat pipe
The connection of peripheral spiral bar liner bellows, make that first and last spiral bar both ends are smooth, appearance is good；The product structure is simple, novel, ruler
Very little stabilization and production are quick.
Further, the bottom periphery of socket is equipped with holding groove.Holding groove keeps the liner bellows of socket and spiral bar fast
Speed is located by connecting.
Further, the outer wall of socket is equipped with convex ribs.Convex ribs make the connection of the liner bellows of socket and spiral bar increase friction
Power, convex ribs coordinate with holding groove limits the liner bellows of spiral bar, and transition piece is made to keep stable connection with spiral bar.
Further, socket is additionally provided with notch.Because notch makes socket have elastic characteristic, when socket and carat pipe periphery spiral
When the liner bellows connection cooperation of muscle, the end of socket because notch gap can stress become smaller, and sprung back after coordinating in place
It resets, installation connection is quick and easy, and reliability is high, is completely embedded.
Further, blind slot is waist type groove.It is equipped with waist type groove on centrum, keeps the liner transition piece real under some strength
Freely, flexibility is more preferable for now bending.
Further, a layered material layer is equipped in blind slot.The bed of material in a certain range can with the bending of transition piece and internal layer receive
Contracting, outer elongate keep the draftability and flexibility of centrum.
Further, which is injection molding.Injection molding keeps the transition piece high-quality, and production is quick.
The utility model has the beneficial effects that：
1, the liner transition piece is made of cone and socket two parts, and it is blind that entire outer surface is equipped with staggeredly clearly demarcated waist type
Slot, and being formed by injection molding makes the liner transition piece can be along the free bend of 360 degree of axis direction of rotation, and intensity is high；It is bored
Body structure can be that the liner bellows of the peripheral spiral bar head and end of carat pipe distinguishes ascending and descending conjunction
Transition is managed, is connect with the peripheral spiral bar liner bellows of carat pipe using socket, makes that first and last spiral bar both ends are smooth, appearance
It is good；The product structure is simple, novel, and dimensionally stable and production are quick.
2, the socket of the liner transition piece is elastic socket, and a certain number of notches and convex ribs are not only distributed in it, and
Its bottom periphery is additionally provided with holding groove.After convex ribs and holding groove the cooperation limit of socket, the liner wave of socket and spiral bar
Line pipe both ends can be located by connecting rapidly, convenient and reliable.
3, it is designed with relatively thin layered material layer below the waist type blind slot of the transition piece, which in a certain range can be with transition
The bending of part and internal layer is shunk, outer elongate, make that product bending degree of freedom is high, structure novel.
