Abstract
The utility model is related to a kind of Anti-loose bolt nut assembly, is connected the problem of easy loosening with the regular screw threads of external screw thread nut for internal thread bolt, and spring and locking pin are set in bolt inner space, and nut end face sets thread form structure；Spanner stretches into six side in nut when tightening, compression spring makes locking pin, and inwardly motion departs from nut, after fastening is finished, recoil of spring is pushed in dynamic locking pin reset inserted num thread form, the disengaging and reset of locking pin are realized using spring force, the effect of automatic loose proof after threaded connection fastening is reached.Make full use of the space of bolt axis load smaller part position, and pressure and the screen resilience of spring using spanner, realization locking pin disengaging when tightening, fasten and finish rear locking pin reset locking, prevent threaded connection from loosening, screw thread is tightened and locking coordination, is not interfere with each other.For screw retention design provides new thinking, with practical value higher, it is worthy of popularization.
Description
Technical field
The utility model is related to a kind of safe and reliable, Anti-loose bolt nut assembly of fast demountable.
Background technology
Threaded connection is typically made up of nuts and bolt two parts, belongs to and is detachably connected, by bolt, the screw-in of nut
Back-out is realized two connections with through hole machine components and is separated.When equipment operation where connection, can inevitably produce
Raw vibration, causes threaded connection to be rocked, and causes thread abrasion so that fastening effect is deteriorated, in some instances it may even be possible to causes nut to screw out and draws
Joint failure is played, the reliability of equipment is influenceed.In the Joint failure of key position, the possible direct or indirect life for threatening people
Life.
Utility model content
The purpose of this utility model is：
The purpose of this utility model is the demand for thread connection anti-loose, there is provided a kind of safe and reliable, can quickly be torn open
The Anti-loose bolt nut assembly of dress.
Technical solution of the present utility model：
The problem that the utility model easily loosens for regular screw threads connection, using a kind of bolt female connection structure,
Bolt inside sets spring and locking pin, and nut end face sets thread form structure, is realized by locking pin inserted num thread form
The reliability of threaded connection is locking.
A kind of Anti-loose bolt nut assembly, including：Nut, bolt, spring, pad, lead column pin and sleeve cartridge module；Bullet
Spring, pad, lead column pin and sleeve cartridge module are sequentially connected vertically, and pilot hole is provided with vertically in bolt, are oriented to pin
Can be moved along pilot hole, nut end face is set to thread form structure.
Sleeve assembly includes：Stopper, sleeve, locking pin；Phase interaction when sleeve assembly undertaking spring and spanner are stretched into
Firmly, wherein, stopper use self-lubricating nonmetallic materials, during preventing nut from screwing in stopper scratch the contact with nut and spanner
Face, and reduce the frictional force of relative motion, after screw bolt and nut is tightened, in locking pin inserted num thread form.
The utility model has the advantage that and beneficial effect：
The utility model this have the advantage that load smaller part position sets locking device in the middle part of bolt, and spiral shell is realized by inside
Line is locking.Lightweight construction, occupies little space, and is easily installed and dismantles.The beneficial effects of the utility model are, in the middle part of bolt
Anti-loose structure is set, the space of bolt axis load smaller part position is made full use of, and utilizes the pressure of spanner and returning for spring
Elastic force, realization locking pin disengaging when tightening, fastening finishes rear locking pin reset locking, prevents threaded connection loosening, makes spiral shell
Line is tightened and locking coordination, does not interfere with each other.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of Anti-loose bolt nut assembly, including：Nut 1, bolt 2, spring 3, pad 4, guiding pin 5 and sleeve group
Part 6；Spring 3, pad 4, guiding pin 5 and sleeve assembly 6 are sequentially connected vertically, and guiding is provided with vertically in bolt 2
Hole, being oriented to pin 5 can move along pilot hole, and the end face of nut 1 is set to thread form structure.
Sleeve assembly 6 includes：Stopper 7, sleeve 8, locking pin 9；Sleeve assembly 6 (see Fig. 3) accepts spring 3 and spanner is stretched
Fashionable interaction force, wherein, stopper 7 use self-lubricating nonmetallic materials, with prevent nut 1 screw in when stopper 7 scratch with
After the contact surface of nut 1 and spanner, and reduce the frictional force of relative motion, bolt 2 and nut 1 are tightened, the insertion spiral shell of locking pin 9
In female 1 thread form.
When nut 1 is tightened, spanner is stretched into nut 1 in six sides, spanner stretches into action and promotes sleeve assembly 6 to bolt
2 internal motions, by the compression spring 3 of pad 4, move the pilot hole along bolt 2 of guiding pin 5, and drive locking pin 9 with
The thread form of nut 1 departs from, and releases the locking effect of component, can be now screwed into nut 1 with rotating spanner, while being oriented to pin 5 and spiral shell
Pilot hole coordinates on bolt 2, prevents the inner structural members such as spring 3, sleeve assembly 6 from turning with the spinning movement that is screwed into of spanner and nut 1
It is dynamic.
After fastening is finished, spanner is taken out from six sides in nut 1, the screen resilience of spring 3 is acted on pad 4, promote sleeve
The homing of component 6, drives in the locking thread form of 9 inserted num of pin 1, and now nut 1 is relatively unrotatable with sleeve assembly 6,
Relatively rotated with reference to sleeve assembly 6 and bolt 2 and limited by guiding pin 5 and the pilot hole of bolt 2, ultimately form reliable locking, had
Effect prevents the threaded connection of the nut of nut 1 and 2 from loosening.
