Description
Technical field
The utility model relates to a kind of joint structure.
Background technique
In mechanical field, conventional tube and tube Placement has Welded fitting, Bite type fittings, horn mouth formula pipe joint at present.These structures are applicable in different pipe joint locking structures, and every kind of mode all has pluses and minuses: during Welded fitting assembling, need welding, need to adopt thick walled steel tube, and welding job amount is large, non-dismountable, application area is little; FERRULETYPE exists that boundary dimension is large, easily cause the shortcoming of leakage in elevated pressures environment; Horn mouth formula exist locking not firm, seal unreliable, the easy loosening drawback that causes leakage of oil.
Summary of the invention
The purpose of this utility model is to provide a kind of joint structure, has simple in structure, easy accessibility, withstand voltage height, locks the advantages such as firm, sealing is reliable, boundary dimension is little, applicability is strong.
The technical solution of the utility model is, described joint structure comprises pipe joint and assembly, pipe joint end is provided with inside extension pin, tighten up assembly and comprise fitting seat, lock ring, spring seat and Compress Spring, lock ring is fixed on fitting seat, spring seat one end is stuck on lock ring, between the other end and fitting seat, be provided with Compress Spring, on the external diameter of lock ring, be provided with the uniform skewed slot identical with pin quantity on pipe joint, described skewed slot one end is positioned at the end face of pipe joint direction, the other end is positioned at lock ring middle part, and be provided with draw-in groove, described draw-in groove is that skewed slot end is to the extension of the end face of pipe joint direction, the width of skewed slot and draw-in groove is greater than the diameter of pin, on described fitting seat, be provided with the attachment face matching with pipe joint, on attachment face, be provided with O-ring seal.
As another kind of technological scheme of the present utility model, pipe joint end is provided with outside extension pin, tighten up assembly and comprise fitting seat, lock ring, spring seat and Compress Spring, lock ring is fixed on fitting seat, spring seat one end is stuck on lock ring, between the other end and fitting seat, be provided with Compress Spring, on the internal diameter of lock ring, be provided with the uniform skewed slot identical with pin quantity on pipe joint, described skewed slot one end is positioned at the end face of pipe joint direction, the other end is positioned at lock ring middle part, and be provided with draw-in groove, described draw-in groove is that skewed slot end is to the extension of the end face of pipe joint direction, the width of skewed slot and draw-in groove is greater than the diameter of pin, on described fitting seat, be provided with the attachment face matching with pipe joint, on attachment face, be provided with O-ring seal.
Described lock ring is fixed by a pin on fitting seat.
Described pin is uniform a plurality of, is preferably three.
The utility model when mounted, tightens up assembly and is installed on pipe joint and rotation, pipe joint Compress Spring, and pin enters into draw-in groove along skewed slot, realizes and connecting; During disengagement, press and tighten up assembly, the pin on pipe joint is departed from draw-in groove, through rotation, pin is deviate from from skewed slot.The utility model is simple in structure, easy to operate, and the O-ring seal of setting can reach sealing effect, firm, the withstand voltage height of draw-in groove locking of setting.Structure of the present utility model not only can be used the connection at tube and tube, also can be applied on the sealing cover of various containers simultaneously, in aeroengine fuel door structure, has a wide range of applications field.
