Description
Technical field
The utility model relates to the technical field of standard component, especially a kind of anti-loose combination nut.
Background technique
Nuts and washers is usually used together with bolt, and bolt passes through connector and connected piece, and the other end covers upper gasket,
Then attaching nut makes connector and connected piece fasten assembly by the threaded connection of nuts and bolt.Erection sequence is usual
It is first mounting gasket, then screws on nut, nut is pressed on washer.
But when nut is exposed in strong vibration environment, nut can loosen.Meanwhile in mounting gasket and spiral shell
When female, need to pin washer on the other hand, carry out nut assembly on the other hand, be not careful, the washer covered on bolt just falls off, and needs to spend
Take the more time, working efficiency is lower.And some components need often disassembly, replacement, are unfavorable for improving installation effectiveness.
Summary of the invention
Aiming at the problems existing in the prior art, the utility model provides a kind of anti-loose combination nut, can prevent
Nut loosens, while improving installation effectiveness.
To achieve the above object, the utility model provides following technical solution: a kind of anti-loose combination nut, including
The nut body and gasket of coaxial arrangement, the nut body are detachably connected with gasket, the gasket include Upper gasket with
Lower gasket, between the Upper gasket and lower gasket be equipped with locking device, the locking device include be separately positioned on Upper gasket with
On lower gasket and opposite two locking slots of opening, it is all equipped with spring in two locking slot, two locking slot passes through connector
It is connected, the both ends of the connector are respectively protruding into locking slot and inconsistent with spring.
By adopting the above technical scheme, the nut body is detachably connected with gasket, can be pacified gasket before nut is installed
On nut body, the difficulty of installation is reduced, while Upper gasket and lower gasket are distinguished when locking device tightens nut
Thrust is generated to bolts and nuts ontology, the screw thread of the screw thread and nut body that enable bolt is fitted close, so that coupling mechanism force is generated,
Nut loosening is prevented, the anti-loosening property of nut is improved.
Further, axial one end of the nut body is equipped with clamping annular groove, and the corresponding clamping annular groove of lower gasket is equipped with can
The retainer ring to fasten with clamping annular groove.
By adopting the above technical scheme, in this way, nut body and lower gasket may make to pass through clamping annular groove and retainer ring
Engaging is connected, and not only structure is simple, easy to connect, and easy to process.
Further, the both ends of the connector are respectively equipped with fixture block, and the cross-sectional area of the fixture block is greater than locking slot
Opening.
By adopting the above technical scheme, setting can be such that fixture block is stuck in locking slot in this way, to guarantee connector and locking slot
Connection, avoid connector be detached from locking slot.
Further, the locking device is equipped with multiple and circumferentially distributed along gasket.
By adopting the above technical scheme, in this way, the thrust between Upper gasket and lower gasket may make circumferentially uniformly to divide
Cloth maintains the stabilization of Upper gasket and lower gasket.
Further, the end face of the Upper gasket and lower gasket is equipped with rough decorative pattern.
By adopting the above technical scheme, setting can increase rubbing between Upper gasket and bolt, lower gasket and nut body in this way
Power is wiped, Upper gasket is avoided to rotate with lower gasket.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with accompanying drawings and embodiments.
The anti-loose combination nut of one kind as shown in Figure 1, nut body 1 and gasket 2 including coaxial arrangement are described
Nut body 1 is detachably connected with gasket 2, and the gasket 2 includes Upper gasket 21 and lower gasket 22, the Upper gasket 21 and underlay
Between piece 22 be equipped with locking device 3, the locking device 3 include be separately positioned on Upper gasket 21 on lower gasket 22 and be open phase
Pair two locking slots 31, spring 32 is all equipped in two locking slot 31, two locking slot 31 is connected by connector 33, institute
The both ends for stating connector 33 are respectively protruding into locking slot 31 and inconsistent with spring 32.The nut body 1 and gasket 2 are detachable
Gasket 2 can be mounted on nut body 1 before nut is installed, reduce the difficulty of installation, while locking device 3 makes by connection
It obtains Upper gasket 21 and lower gasket 22 when nut is tightened and thrust is generated to bolts and nuts ontology 1 respectively, enable the screw thread and spiral shell of bolt
The screw thread of maternal body 1 is fitted close, to generate coupling mechanism force, is prevented nut loosening, is improved the anti-loosening property of nut.
Axial one end of the nut body 1 is equipped with clamping annular groove 5, and the corresponding clamping annular groove 5 of lower gasket 22 is equipped with can be with card
Connect the retainer ring 6 that annular groove 5 fastens.In this way, nut body 1 and lower gasket 22 may make to pass through clamping annular groove 5 and retainer ring 6
Engaging is connected, and not only structure is simple, easy to connect, and easy to process.
The both ends of the connector 33 are respectively equipped with fixture block 4, and the cross-sectional area of the fixture block 4 is greater than the opening of locking slot 31
Place.Setting can be such that fixture block 4 is stuck in locking slot 31 in this way, to guarantee the connection of connector 33 Yu locking slot 31, avoid connecting
Part 33 is detached from locking slot 31.
The locking device 3 is equipped with multiple and circumferentially distributed along gasket 2.In this way, may make Upper gasket 21 and underlay
Thrust between piece 22 is uniformly distributed circumferentially, and maintains the stabilization of Upper gasket 21 and lower gasket 22.
The end face of the Upper gasket 21 and lower gasket 22 is equipped with rough decorative pattern.Setting can increase upper pad in this way
Frictional force between piece 21 and bolt, lower gasket 22 and nut body 1, avoids Upper gasket 21 from rotating with lower gasket 22.
