Abstract
The utility model relates to an ear-type hose clamp with an internal bushing ring, which is characterized in that the ear-type hose clamp consists of an ear-type metal jacket which is formed by stretching metallic material and the internal bushing ring inserted in the ear-type metal jacket. The upper part of the ear-type metal jacket is manufactured with hose clamp ears; the top of the hose clamp ear is provided with a concave cochleae; one side of the ear-type metal jacket is provided with an inward rolled edge and a groove; the internal bushing ring is a non-sealed metal circular ring; one side of the internal bushing ring is provided with an outward rolled edge and a stop opening. The non-sealed end of the inner bushing ring is provided with a lug boss; and the other non-sealed end is provided with a recess matched with the lug boss. The ear-type hose clamp has the advantages that the internal bushing ring is integrated with the metal jacket; the ear-type hose clamp has high strength, and can be prevented from being broken under weather-beaten environment for long term and different pressures; when the ear-type hose clamp is used, just the hose clamp ears are clamped so that the ear-type metal jacket is contracted and the internal bushing ring is also contracted; the lug boss and the recess on both ends are alternately superposed to form a sealed metal circular ring of 360 degrees. The ear-type hose clamp is simple in structure, is operated conveniently, and can ensure pipes to be connected airtightly, accurately and reliably.
Description
Technical field
The utility model assembling pipe joint particularly relates to a kind of ear-type throat hoop with inner bushing ring.
Background technique
Along with the development of society and the progress of science, international and domestic pipeline industry has entered new developing period.The various pipelines of heat supplies such as a large amount of aluminium-plastic composite pipes, PEX pipe, PP-R pipe, water supply, air feed arise at the historic moment.The appearance of these novel pipeline materials, the variation of having brought matter for human life and life quality.Need to connect when pipeline uses, the connection of pipeline generally is made up of three parts: i.e. pipeline, pipe joint and larynx hoop (claiming clip again).Under the fixed prerequisite of pipeline and pipe joint, the larynx hoop is to the connection person of the rising important function of pipeline.The larynx hoop will reach sealing and firm requirement on the one hand, also should make it in use easy for installation, the existing steel band fastening-pressing type larynx hoop that rolls, under rugged environment of exposing to the weather for a long time and different pressures, be easy to generate fracture, cause phenomenons such as pipe leakage and gas leakage to take place, its ear deformationization of the clip that has in addition is excessive, ear hoop internal diameter regulation range is dwindled, thereby do not reach theoretical regulation range.
Summary of the invention
The utility model provides a kind of be applicable to various pipeline connections, high strength, easy to operate and can guarantee the ear-type throat hoop of the band inner bushing ring of the sealing, accuracy and the reliability that connect for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the ear-type throat hoop of band inner bushing ring, it is characterized in that: it is to be made of ear formula metal-coating and plug-in mounting inner bushing ring within it that the metallic material stretching forms, described ear formula metal-coating top is shaped on larynx hoop ear, the top of ear formula metal-coating larynx hoop ear is shaped on interior female lug nest, crimping and groove in ear formula metal-coating one side is shaped on.The above inner bushing ring is non-closed metal annulus, on one side it is shaped on flanging and position-limitting mouth, non-sealing one end is provided with plush copper, and the non-sealing the other end is shaped on the recess that matches with plush copper.
The utility model can also adopt following technological scheme:
The top of described ear formula metal-coating larynx hoop ear is shaped on three interior female lug nests.
Have three grooves on the interior crimping of described ear formula metal-coating is axial.
Three slot lengths on the interior crimping of described ear formula metal-coating is axial equate.
The width of described larynx hoop ear equates with the width of ear formula metal-coating.
Advantage and the good effect that the utlity model has are: because ear formula metal-coating of the present utility model is to stretch by metallic material to form, inner bushing ring is inserted the In-Ear metal-coating formula structure that becomes one, its intensity height, and under rugged environment of exposing to the weather for a long time and different pressures, can not rupture; The metal inner lining ring of ear-type throat hoop has position-limitting mouth and two ends plush copper and notch configuration, during use, only need to clamp the ear of ear-type throat hoop, ear formula metal-coating is tightened up, its inner bushing ring also tightens up thereupon, staggered sealing, the metal cirque of 360 ° of sealings of formation of overlapping of the plush copper at two ends and recess; Whether inner bushing ring has the position-limitting mouth of flanging, can indicate the clamped condition of ear-type throat hoop, be convenient to the operator and observe clamping and put in place.In addition, this larynx cuff structure is simple, easy to operate, has guaranteed sealing, accuracy and reliability that pipeline connects.
