Abstract
An inner core of double-seal rubber hose coupling comprises a core tail and a taper head, and is characterized in that the taper head is provided with two O-shaped grooves. The utility model aims to provide an inner core of double-seal rubber hose coupling with simple structure which is tensile, shakeproof, and can stand high pressure, wherein the hose coupling is not easy to leak.
Description
Technical field
The utility model relates to a kind of rubber hose coupling inner core, relates in particular to a kind of inner core that is used for the oil circuit rubber hose coupling.
Background technique
In the engineering mechanical device field, oil circuit pipe fitting application especially is because the needs that equipment uses require the oil circuit pipe fitting must possess the characteristics of tension, antidetonation, anti-high pressure.Therefore, the structure at the rubber hose coupling position of oil circuit pipe fitting and the quality of performance seem particularly important.The rubber hose coupling inner core is the vitals of rubber hose coupling.In actual use, present normally used rubber hose coupling inner core tapering head adopts single O shape groove structure usually, in actual use, Chang Yinwei processing or assembly error make pipeline the seepage phenomenon occur, influenced the normal use of machine, machine is shortened working life greatly.
The model utility content
The utility model aims to provide a kind of simple in structure, and tension, antidetonation, anti-high pressure, pipe joint be the double-sealing rubber hose coupling inner core of easy to leak not.
The technological scheme that the utility model adopted is: double-sealing rubber hose coupling inner core comprises core tail and tapering head; It is characterized in that described tapering head is provided with twice O shape groove.
Be provided with hold-down ring in the described O shape groove.
The beneficial effects of the utility model are: use inner core tapering head has the rubber hose coupling of twice O shape groove, has effectively remedied the defective of the single O shape of the present use seal of tube, has tension, antidetonation, anti-high pressure, and pipe joint is the advantage of easy to leak not.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model Fig. 1 tapering head cross-sectional schematic.
Embodiment
An embodiment's of the utility model structure, as shown in drawings, the double-sealing rubber hose coupling comprises core tail 1, tapering head 2, O shape groove 3, hold-down ring 4.Core tail 1 is traditional rubber hose coupling core arrangement, is provided with twice O shape groove 3 on core tail 1 a relative end tapering head 2.In actual use, in order to improve inner core sealing and assembling fastness, in twice O shape groove 3, be provided with hold-down ring 4.
Claims (2)
