Description
Technical field
The utility model is related to a kind of fixing piece, more particularly to a kind of stress loose-proof self-lock nut.
Background technology
Nut be it is a kind of with bolt or screw rod screw up after implement to be locked the part of function.Traditional nut is mainly by this
Body, the through-hole being opened on ontology and the screw thread composition in through-hole.
In use, after bolt or screw rod are screwed up with nut implementation, bolt or screw rod are easy to be acted on by external force
It is loosened with the screw thread implementation in nut through hole, fixed unstable situation occurs.
With the field technology, personnel are constantly developed, and occur some on market and data with bolt or after screw rod locking
Then the nut of anti-retrogression, such nut prevent self-locking mainly by opening up arcuation slot on the inner walls of the via in arcuation slot
Steel ball.Although having self-locking function, its processing technology is relatively complicated, and cost is higher.
Invention content
In view of the deficienciess of the prior art, the utility model provides, one kind is easy to process, reduces production cost, structure
Simple stress loose-proof self-lock nut.
To achieve the above object, the utility model provides following technical solution：A kind of stress loose-proof self-lock nut, including
There is ontology, the through-hole that is opened on ontology and the screw thread in through-hole, it is characterised in that：It opens the lateral side of the ontology
Equipped with the installation gap with through-hole vertical connection, the elastic collar extended in the middle part of through-hole, the elastic card are equipped at installation gap
Enclosing has the locking hole that be adapted to through-hole, the elastic collar be in through-hole it is interior after locking hole thereon axle center and body through-holes
Axle center eccentric setting, and the plugging sheet for blocking installation gap can be inserted at installation gap.
Using above-mentioned technical proposal, in assembling process, elastic collar is positioned over by installation gap in through-hole, then
Installation gap is implemented to block by plugging sheet, when bolt or screw rod are screwed up with through-hole implementation, screw rod or bolt with it is eccentric
Elastic collar implements locking, with the rotation of screw rod or bolt, the coupling mechanism force of elastic collar is promoted to become larger, until completely will
Screw rod or bolt are positioned in through-hole.And after screw rod or bolts and nuts locking, external force can not cause to loosen to bolt or screw rod.
It is not only easy to process, but also low processing cost, save production cost.
The utility model is further arranged to：The inner wall of the locking hole of elastic collar is inclined-plane.
Using above-mentioned technical proposal, setting in this way makes the cooperation between bolt or screw rod and locking hole more closely, locking
Power is more preferable.
The utility model is further set as：Plugging sheet is with installation gap in interference fit.
Using above-mentioned technical proposal, setting in this way is convenient for assembling, and sound construction after closure, is not in loosen.
The utility model is further set as：There is angle, the angle between the inner wall and ontology longitudinal terminal surface of through-hole
It is 3 ° -5 °.
Using above-mentioned technical proposal, setting in this way increases screw rod or friction when bolt screws up with through-hole wall screw thread
Power reduces the gap between being screwed.
The utility model is further described below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
A kind of stress loose-proof self-lock nut as shown in Figure 1 includes ontology 1, is opened on ontology 1 through-hole 11 and
Screw thread 12 in through-hole 11, the lateral side of ontology 1 offer the installation gap 13 with 11 vertical connection of through-hole, and installation lacks
The elastic collar 2 for extending to 11 middle part of through-hole is equipped at mouth 13, which has the locking hole 21 being adapted to through-hole, should
The axle center eccentric setting in the axle center and 1 through-hole 11 of ontology of locking hole 21 thereon after elastic collar 2 is in through-hole 11, and installation
The plugging sheet 3 for blocking installation gap 13 can be inserted at notch 13.Said program passes through elastic collar 2 in assembling process
Installation gap 13 is positioned in through-hole 11, then implements to block by installation gap 13 by plugging sheet 3, when bolt or screw rod and is led to
When hole 11 implements to screw up, screw rod or bolt are implemented to lock with eccentric elastic collar 2, with the rotation of screw rod or bolt, promote
The coupling mechanism force of elastic collar 2 becomes larger, until screw rod or bolt are positioned in through-hole 11 completely.And screw rod or bolt and spiral shell
After mother's locking, external force can not cause to loosen to bolt or screw rod.It is not only easy to process, but also low processing cost, save life
Produce cost.
It is anti-loose in order to further ensure coupling mechanism force in the utility model embodiment.The locking hole of elastic collar 2
21 inner wall is inclined-plane.For the ease of the installation between plugging sheet 3 and installation gap 13, plugging sheet 3 was in installation gap 13
It is full of cooperation.Certainly, it should be noted that plugging sheet 3 can also implement connection and feasible by positioning pin and ontology 1.
For the frictional force for increasing screw rod or when bolt screws up with 11 inner thread of through-hole, between reducing between being screwed
Gap.There is angle, which is 3 ° -5 ° between 1 longitudinal terminal surface of inner wall and ontology of through-hole 11.
