Abstract
The utility model relates to a cover tightly overlaps in pipe end protection pipeline and firm rising, stainless steel rises and tightly overlaps's shape is hollow ring shape cylinder cover, and the cylinder jacket wall of this ring shape cylinder cover is thin, and cylinder cover top neckedout forms an outer edge of ring form, and this ring form is outer to form a ring form ring slot along incurving along the cylinder cover again with cylinder cover surface, simple structure, but the practicality is strong, the cover plays the guard action at the pipe end, rise than plastics and tightly overlap, fast firmly cracked problem can not appear.
Description
Technical field
The utility model belongs to steel and moulds Manifold technology field, relate to a kind of use in the process of conveying water be placed on pipe end protective tube pipeline connector and the stainless steel expansion sleeve of firm tensioning tube joint.
Background technique
In daily life; pipeline is commonly used in each place in life; pipeline mostly is Steel material or plastic materials; the pipeline of Steel material there will be the problem of getting rusty in Long-Time Service; although the pipeline of plastic materials can not get rusty but firm not as Steel material, if especially Steel material pipeline pipe end can not have good protection, so pipeline can shorten working life greatly; and it is bad to there will be sealing, the phenomenon such as to leak.If pipe end cover on a cover, so cover firmly can not be fixed on pipe end, does not have any effect, if use plastics expansion sleeve, utilize elasticity of plastics to be enclosed within pipe end, so can there is the problem be split up for a long time due to the reason of own material in plastics expansion sleeve.
Summary of the invention
Deficiency during the purpose of this utility model is to solve the problem and provide a kind of stainless steel expansion sleeve to be contained in water pipe line pipe end, play protection pipe end, self is stainless steel expansion sleeve firmly.
The purpose of this utility model is achieved in that the shape of described stainless steel expansion sleeve is the ring cylindrical sleeve of hollow, the cylinder jacket wall of this ring cylindrical sleeve is thin, cylindrical sleeve top is bent outwardly formation circular outer, and this circular outer curves inwardly along cylindrical sleeve again and forms a circular annulus slot with cylindrical sleeve outer surface.
The utility model has following good effect: 1, structure is simple, but practical; 2, be enclosed within pipe end, play a protective role; 3, comparatively plastics expansion sleeve, the solid problem that firmly there will not be fracture.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of stainless steel expansion sleeve of the utility model.
Be labeled as in figure: 1, cylindrical sleeve; 2, circular outer; 3, annulus slot.
Embodiment
A kind of making method of the present utility model is by a bit of for rectangle steel bar prolongation edge contraction, folding twice, and form groove, rectangle steel bar two ends are welded into ring-shaped cylinder as Fig. 1.
The shape of described stainless steel expansion sleeve is the ring cylindrical sleeve 1 closed of hollow, cylindrical sleeve 1 wall of this ring cylindrical sleeve 1 is thin, cylindrical sleeve 1 top is bent outwardly the circular outer 2 of formation one, and this circular outer curves inwardly along cylindrical sleeve 1 again and forms a circular annulus slot 3 with cylindrical sleeve outer surface.
Expansion sleeve is ring-shaped cylinder, and cylindrical wall is thin, and capital is bent outwardly as outer and post jamb outer surface form a circular annulus slot 3.The pipe end of aqueduct can be inserted in circular annulus slot 3, expansion sleeve outer is tightly sleeved on the tube end outer surface of aqueduct, this ensures that thering aqueduct pipe end internal surface is enclosed within ring cylindrical sleeve 1 outer wall, end is inserted in circular annulus slot 3, by circular annulus slot 3, aqueduct pipe end is wrapped up, thus make aqueduct pipe end non-corrosive.
This stainless steel expansion sleeve by belt tensioner directly by tensioner on the internal surface of aqueduct and the pipe end of aqueduct, the end of whole aqueduct is compressed by the utility model.
During use, described expansion sleeve is enclosed within the conduit pipe pipe end needing to add expansion sleeve, by belt tensioner, cylindrical wall of the present utility model is pressed on the inner tubal wall of aqueduct.
Claims (1)
1. a stainless steel expansion sleeve, it is characterized in that: the shape of described stainless steel expansion sleeve is the ring cylindrical sleeve (1) of hollow, cylindrical sleeve (1) wall of this ring cylindrical sleeve (1) is thin, cylindrical sleeve top is bent outwardly formation circular outer (3), and this circular outer (3) curves inwardly along cylindrical sleeve (1) again and forms a circular annulus slot (2) with cylindrical sleeve (1) outer surface.
