Description
Technical field
The utility model is related to pipe fittings to connect accessory technical field, specifically, being to be related to a kind of fastening-pressing type hose connection
Device.
Background technology
Common connector generally comprises fuse and housing, and fuse is two mutually independent zero with outer be sleeved on after the completion of production
Part will such as be withheld with rubber hose after people buy this connector and connect, often also need to carry out it is following operate, first will be outer
It is sleeved in rubber hose, then fuse is inserted into rubber hose, finally housing is withheld using special equipment, by housing
Deforming, which finally makes rubber hose be withheld with connector, links together.Although this connector has been widely adopted, from aforesaid operations
Process we be not difficult to find out, with rubber hose to withhold attended operation cumbersome；Due to being split type connector, accuracy
It is low, it will cause housing to withhold stress inconsistent, it is yielding, to which sealing performance can be deteriorated.
Therefore, in the prior art, split type connector and rubber hose withhold that operation is more complicated, and accuracy is low, will
Housing can be caused to withhold stress inconsistent, it is yielding, the problems such as to reduce sealing performance, design a kind of fastening-pressing type hose connection
Device is the current technical issues that need to address.
Invention content
Goal of the invention：It is in view of the drawbacks of the prior art and insufficient, solve that there are split type connectors to withhold with rubber hose
Operate more complicated, accuracy is low, it will cause housing to withhold stress inconsistent, it is yielding, it is asked to reduce sealing performance etc.
Topic, applicant improve by repeatedly practice, devise a kind of fastening-pressing type hose attachment device.
Technical solution：In order to achieve the above-mentioned object of the invention, a kind of fastening-pressing type hose attachment device, including nut and main body,
The main body includes sleeve and inner core, and the inner core is axially through the internal core rod for having conical through-hole, and the sleeve is U-typed
Sleeve, the sleeve and inner core are that integral type is cast, and are provided with annular groove on the sleeve lining, the one of the inner core
End outer wall is provided with screw thread, and the other end outer wall of the inner core is provided with annular cone tooth, and the nut is provided with screw thread with inner core
One end connection, O-shaped sealing element is provided between the nut and inner core, O-shaped sealing is provided between the sleeve and inner core
Part, the angle between the conical surface and inner core axes of the inner core conical through-hole are 30 °.
Preferably, the nut is hexagonal (hexagon)nut.
Preferably, having a certain distance between the sleeve lining and the other end outer wall of the inner core.
Preferably, the O-shaped sealing element is elastic polyurethane sealing element.
Preferably, the compressive resistance of the sleeve ranging from 250-300kg/cm2.
Advantageous effect：Compared with prior art, advantage is the utility model：
1, the utility model is that the connector of integral type casting not will produce some deviations of material in casting process,
Will not occur phenomena such as hardness is uneven when heat treatment, improve the precision of connector, avoid the deformation of sleeve.
2, it is provided with O-shaped sealing element between nut and inner core described in the utility model, is arranged between the sleeve and inner core
There is O-shaped sealing element, the angle between the conical surface and inner core axes of the inner core conical through-hole is 30 °, improves whole sealing
Performance.
