Abstract
The present invention provides a kind of anti-self-tightening quick change nut, including nut body and nut cap, nut body is provided with internal thread, nut cap is between nut body and required securing objects, supporting mass is arranged between nut body and nut cap to separate, nut body and nut cap can relatively rotate between the two, and nut body does not contact under the buffer action of nut cap and supporting mass between required securing objects.On the periphery of nut body and nut cap outer sleeve body is cased with to be connected the two, the disc that both nut body and nut cap 5 are connected to each other is provided with outer protrusion, at the annulus up and down of outer sleeve body inside bending withhold the outer protrusion on both nut body and nut cap.The present invention makes the reaction force of cutting sheet act predominantly on nut cap, in non-conducting to nut body, achievees the purpose that prevent nut self-tightening by the way that nut is carried out split-type design.
Description
Technical field
The invention belongs to mechanical spare and accessory parts fields, and in particular to a kind of anti-self-tightening quick change nut.
Background technology
Currently, this kind of machinery such as sander, cutting machine mostly uses plain nut when installing cutting sheet or grinding disc
Fasten cutting sheet or grinding disc.After long-term work, fastening nut can be caused serious self-tightening phenomenon, unloaded by reaction force acts
It is difficult to be removed from machine when load.
Invention content
For the above technological deficiency, the present invention provides a kind of anti-self-tightening quick change nut.It can be with effective solution nut self-tightening
The problem of.
The technical solution adopted by the present invention is：A kind of anti-self-tightening quick change nut, including nut body and nut cap, nut body are opened
There is internal thread, nut cap is arranged supporting mass between nut body and required securing objects, between nut body and nut cap and separates,
Nut body and nut cap can relatively rotate between the two, nut body under the buffer action of nut cap and supporting mass with it is required tight
Gu not contacted between object.
Preferably, nut body is arranged to convex, and nut cap is sleeved at the boss of nut body.
Preferably, outer sleeve body is cased on the periphery of nut body and nut cap to be connected the two.
Preferably, the disc that both nut body and nut cap are connected to each other is provided with outer protrusion, at the annulus up and down of outer sleeve body to
Interior bending withholds the outer protrusion on both nut body and nut cap.
Preferably, the supporting mass is to be arranged in a circular steel ball.
Preferably, the shape phase of arc-shaped groove and steel ball is provided on nut body and nut cap with the contact site of steel ball
It coincide.
Preferably, steel ball is located at the groove of nut body.
Preferably, circular ring type shrapnel is set between nut body and nut cap.
Preferably, steel ball and groove identical with steel ball quantity can be engaged in shape by being provided on the inner ring circumference of shrapnel.
The present invention makes the reaction force of cutting sheet act predominantly on nut cap by the way that nut is carried out split-type design,
In non-conducting to nut body, achieve the purpose that prevent nut self-tightening.

Fig. 2 is the sectional view of the present invention；
Structural schematic diagram when Fig. 3 is present invention application.
In figure：1- nut bodies；2- steel balls；3- shrapnels；4- outer sleeve bodies；5- nut caps；6- cutting sheets.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings, as shown, the present invention provides one
Kind anti-self-tightening quick change nut, including nut body 1 and nut cap 5, nut body 1 are provided with internal thread, nut cap 5 be located at nut body 1 and
Between required securing objects, nut body 1 is arranged to convex, and nut cap 5 is sleeved at the boss of nut body 1.1 He of nut body
It is cased with outer sleeve body 4 on the periphery of nut cap 5 to be connected the two, the disc that both nut body 1 and nut cap 5 are connected to each other is opened
Have an outer protrusion, at the annulus up and down of outer sleeve body 4 inside bending withhold the outer protrusion in 5 the two of nut body 1 and nut cap.
Supporting mass is arranged between nut body 1 and nut cap 5 to separate, supporting mass can be to be arranged in a circular steel ball 2,
Can also be to be arranged in a circular steel column, therefore nut body 1 and nut cap 5 can relatively rotate between the two, nut body 1
It is not contacted between required securing objects under the buffer action of nut cap 5 and supporting mass.
Further, arc-shaped groove and steel ball 2 are provided with the contact site of steel ball 2 on nut body 1 and nut cap 5
Shape match, steel ball 2 is located at the groove of nut body 1.
Further, circular ring type shrapnel 3 is set between nut body 1 and nut cap 5, is provided on the inner ring circumference of shrapnel 3
Steel ball 2 can be engaged in shape and counts identical groove with steel ball 2.The effect of shrapnel 3 is to give nut body 1 one buffering frictions
Power is prevented when cutting sheet 6 starts and rotates, and nut body 1 follows linkage rotation, and self-tightening occurs.
As shown in figure 3, the operation principle of the present invention is that：Fast nut is tightened by hand, cutting sheet 6 is fastened on machine
Afterwards, when machine works normally, cutting sheet 6 can be acted on by reaction force on nut cap 5, and nut cap 5 is caused to rotate, but nut
There are many steel balls 2 in 5 lower section of lid, and frictional force very little between nut cap 5 and nut body 1, frictional force is not enough to cause nut body 1 certainly
Tightly, so self-tightening does not occur for quick change nut, easily fast nut can be removed from machine with hand.
Structure of the invention reasonable design is ingenious, ideally solves the problems, such as nut self-tightening.
The foregoing is merely the preferred embodiment of the present invention, it is noted that comes for those of ordinary skill in the art
It says, without departing from the concept of the premise of the invention, modification and improvement can also be made, should all belong to the protection model of the present invention
It encloses.
