Abstract
The invention relates to a self-locking snap ring which comprises a snap ring body composed of multiple connecting joints hinged together in sequence, and a lock assembly. One end of a bolt of the lock assembly is hinged to one end of the snap ring body. The other end of the bolt penetrates the other end of the snap ring body and a swivel nut and is then provided with a nut. A lock shell is arranged outside the swivel nut. A spring is pressed on the lock shell and the swivel nut. The end of the lock shell is matched with the outer contour of the nut. The swivel nut is provided with a pin. The pin extends into an axial groove of the bolt and an axial through hole of the lock shell respectively. Compared with a traditional quick-detached snap ring, the self-locking snap ring has the beneficial effects that the self-locking and detaching functions are more convenient, the snap ring is rapidly installed, locked and detached, and the requirements for installation reliability and repair economic efficiency of the snap ring are met.
Description
Technical field
Patent of the present invention relates to a kind of snap ring, and especially a kind of snap ring with auto-lock function, realizes the installation of snap ring itself, locking and dismounting.
Background technique
Snap ring is applied in multiple field, applies more in aviation field, and snap ring in use, for ensureing that clamping is firm, generally carries out locking device to quick-release snap ring again after clamping.The locking device of now more advanced snap ring all possesses auto-lock function.Meanwhile, in order to ensure the Economy of reliability and the maintenance of installing, needing snap ring can install fast, lock and dismantle, still there is not the snap ring simultaneously possessing this function at present.
Summary of the invention
The object of this invention is to provide a kind of snap ring, described snap ring not only possesses auto-lock function, can also realize the installation fast of snap ring, locking and dismounting simultaneously, realize the requirement of its installation reliability and maintenance and detection.
Concrete technological scheme of the present invention is, self-locking snap ring comprises by snap ring body and lock set, described snap ring body is made up of several order hinge joint connection joints together, lock set comprises bolt, nut, spring, swivel nut, lock housing body, described bolt one end hinge joint is in one end of snap ring body, the other end is through mounting nuts after the other end of snap ring body and swivel nut, nut is by swivel nut tension snap ring body, lock housing body is arranged on swivel nut outside, spring is pressed on the step of lock enclosure interior and swivel nut outer installment respectively, lock housing end of body is by being positioned at nut outside and coordinating with nut external frame under the effect of spring, swivel nut is provided with pin, bolt is provided with axial groove, lock housing body is provided with axial hole, described pin extends in the axial groove of bolt and the axial hole of lock housing body respectively.Described snap ring body Internal periphery shape is arranged according to clamping unit.Be provided with spring seat between the step of lock housing body and spring, spring is pressed on spring seat, and upper the installing of the step of swivel nut is equipped with liner, and spring is pressed on liner.Nut is hexagon nut, and the Internal periphery of lock housing body and nut screw connection is interior six shapes or interior ten dihedrons, or uniform dodecagon shape.
Patent of the present invention relates to a kind of novel self-locking manner, possesses auto-lock function, and it than the self-locking of traditional quick-release snap ring and disassembling function convenient, ensure quick-release snap ring clamping firmly simultaneously, more highlight the function that quick-release snap ring realizes quick-release, thus achieve the installation fast of snap ring, locking and dismounting, ensure the requirement of its installation reliability and maintenance and detection.
