Abstract

The present invention relates to a kind of self-locking snap ring, including the snap ring body and lock set being made up of several the connection joints of order hinge joint together, bolt one end of lock set is linked in one end of snap ring body, the other end installs nut after passing through the other end and swivel nut of snap ring body, lock housing body is arranged on outside swivel nut, spring is press respectively against on lock housing body and swivel nut, lock housing body end coordinates with nut outline, pin is provided with swivel nut, described pin is extended respectively in the axially extending bore of bolt axial groove and lock housing body.Self-locking of the present invention than traditional quick-release snap ring and disassembling function more facilitate, and realize the quick installation, locking and dismounting of snap ring, it is ensured that the requirement of its installation reliability and maintenance and detection.

Description

A kind of self-locking snap ring
Technical field
Patent of the present invention is related to a kind of snap ring, especially a kind of snap ring with auto-lock function, realizes the peace of snap ring in itself Dress, locking and dismounting.
Background technology
Snap ring is applied in multiple fields, applies more in aviation field, and snap ring is when in use, firm for guarantee clamping, Locking device typically is carried out to quick-release snap ring again after clamping.The locking device of now more advanced snap ring all possesses self-locking work( Energy.Meanwhile, in order to ensure the economy of the reliability and maintenance installed, it is necessary to snap ring can quickly be installed, locks and dismantled, There presently does not exist the snap ring for being provided simultaneously with this function.
The content of the invention
It is an object of the invention to provide a kind of snap ring, described snap ring not only possesses auto-lock function, while can also realize Quick installation, locking and the dismounting of snap ring, realize the requirement of its installation reliability and maintenance and detection.
The concrete technical scheme of the present invention is that self-locking snap ring is included by snap ring body and lock set, described snap ring sheet Body is made up of several the connection joints of order hinge joint together, and lock set includes bolt, nut, spring, swivel nut, lock housing body, Described bolt one end hinge joint is in one end of snap ring body, and the other end installs spiral shell after passing through the other end and swivel nut of snap ring body Mother, nut tenses snap ring body by swivel nut, and lock housing body is arranged on outside swivel nut, and spring is press respectively against inside lock housing body and swivel nut On the step that outside is set, lock housing body end in the presence of spring by being located at outside nut and coordinating with nut outline, spiral shell Put and be provided with pin, bolt, which is provided with axial groove, lock housing body, is provided with axially extending bore, and described pin extends respectively to spiral shell In the axial groove of bolt and the axially extending bore of lock housing body.Described snap ring body Internal periphery shape is configured according to clamping unit. Spring base is provided between the step and spring of lock housing body, spring is pressed on spring base, upper install of the step of swivel nut is equipped with lining Pad, spring is pressed on pad.Nut is hex nut, and lock housing body is interior six face shapes or interior 12 face with the Internal periphery that nut coordinates Shape, or uniform dodecagon shape.
Patent of the present invention is related to a kind of new self-locking manner, possesses auto-lock function, and it is than traditional quick-release card The self-locking of ring and disassembling function more facilitate, ensure quick-release snap ring clamping it is firm while, more highlight quick-release snap ring real The function of existing quick-release, it is achieved thereby that the quick installation of snap ring, locking and dismounting, it is ensured that its installation reliability and maintenance are economic The requirement of property.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Fig. 2 is lock set structural representation of the invention.
Embodiment
As illustrated, self-locking snap ring is included by snap ring body and lock set, described snap ring body is by several orders The connection joint 4 of hinge joint together is constituted, and lock set includes bolt 2, nut 3, spring 6, swivel nut 8, lock housing body 10, described spiral shell The hinge joint of the one end of bolt 2 is in one end of snap ring body, and the other end installs nut 3, nut after passing through the other end and swivel nut 8 of snap ring body 3 tense snap ring body by swivel nut 8, and lock housing body 10 is arranged on outside swivel nut 8, and spring 6 is press respectively against the inside of lock housing body 10 and spiral shell On the step that the outside of set 8 is set, the end of lock housing body 10 by be located in the presence of spring 6 outside of nut 3 and with the outline of nut 3 Coordinate, be provided with pin 11 on swivel nut 8, bolt 2, which is provided with axial groove, lock housing body 10, is provided with axially extending bore, described pin Nail 11 is extended respectively in the axial groove of bolt 2 and the axially extending bore of lock housing body 10.Described snap ring body Internal periphery shape root It is configured according to clamping unit.Spring base 9 is provided between the step and spring 6 of lock housing body 10, spring 6 is pressed on spring base 9, Upper install of the step of swivel nut 8 is equipped with pad 7, and spring 6 is pressed on pad 7.Nut 3 is hex nut, lock housing body 10 and nut 3 The Internal periphery of cooperation six face shapes or interior ten dihedron in, or uniform dodecagon shape.
In the use of the present invention, when locked, lock housing body 10 is dialled backward, spring 6 is compressed, and the end of lock housing body 10 departs from After nut 3, nut 3 is tightened.Lock housing body 10 is rebounded by the effect of spring 6 after nut 3 is locked, and spacing and anti-by 11 pins Turn, lock housing body 10 wraps nut 3 inside, and lock housing body 10 is fixed nut 3 by the interior shape of itself, prevents nut 3 Loosen, make clip self-locking firm.When disassembled, lock housing body 10 is dialled backward, spring 6 is compressed, hex nut 3 exposes, comes loose six Angle nut 3, you can dismounting.
