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