Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the use structural schematic diagram of rubber sheet gasket and nut in the prior art；
Fig. 2 is a kind of the schematic diagram of the section structure for anti-loose fastening nut that embodiment provides；
Fig. 3 is the end structure illustration for the nut body that embodiment provides；
Fig. 4 is the structural schematic diagram for the Rigid insert panels that embodiment provides.
Specific embodiment
Referring to Figure 2 to Figure 4, Fig. 2 to Fig. 4 is the structural schematic diagram of one specific embodiment of the utility model.
As shown in Figures 2 to 4, a kind of anti-loose fastening nut, including nut body 1 and rubber sheet gasket 2, the rubber pad
Piece 2 is sleeved on the bolt 4 for cooperating the nut body 1, and the rubber sheet gasket 2 is located at the nut body 1 and fixing piece 3
Between；It further include movable loop 5 and Rigid insert panels 6, the axial ends of the nut body 1 is respectively arranged with radial exterior protrusion
11 and lantern ring mounting portion 12, the movable loop 5 is sleeved on the lantern ring mounting portion 12, and the movable loop 5 be located at it is described
Between radial exterior protrusion 11 and the rubber sheet gasket 2, it is provided between the movable loop 5 and the radial exterior protrusion 11
The Rigid insert panels 6.
When work, the rubber sheet gasket 2 is sleeved on bolt 4 by first choice, then by the movable loop 5 and the nut
1 combined set of ontology is good, then the nut body 1 is screwed on bolt 4, then proceedes to screw the nut body 1 and is allowed to
It is close to the rubber sheet gasket 2, when the nut body 1 is screwed by 2 resistance of rubber sheet gasket, by the Rigid insert panels
Between the 6 insertions movable loop 5 and the radial exterior protrusion 11.
The frictional force generated when being compressed by the rubber sheet gasket 2 prevents the movable loop 5 from occurring relative to fixing piece 3
Relative rotation, then occur that the movable loop 5 will not with the nut body 1 by the intermal force of the movable loop 5
Relative rotation can be realized indirectly and realize spin-ended effect between the nut body 1 and fixing piece 3.Such as background technology part
It is described, a kind of above-mentioned anti-loose fastening nut is applied to the bolt 4 with nut be relative to fixing piece 3 it is fixed,
Therefore it can prevent the nut body 1 that relative rotation occurs with bolt 4, that is, it is several to realize that the reduction of nut body 1 loosens generation
The effect of rate.
Ensure that with the nut body 1 relative rotation does not occur for the movable loop 5, on the one hand most can simply pass through
The frictional force in face of contacting with each other is realized；It is more structurally sound, by being allowed in the lantern ring mounting portion 12 and the setting of movable loop 5
Spin-ended mutual position limiting structure can also make that relative rotation, example will not occur between the lantern ring mounting portion 12 and movable loop 5
Such as:
The lantern ring mounting portion 12 is regular polygon perpendicular to axial cross-sectional shape, and the inner cavity of the movable loop 5 is hung down
It is directly identical perpendicular to axial cross-sectional shape as the lantern ring mounting portion 12 in axial cross-sectional shape.
In said structure, when screwing nut body 1, the meeting of movable loop 5 synchronous rotary, so that
There can be relative motion between the movable loop 5 and the rubber sheet gasket 2, but middle nut and gasket compared to the prior art
Biggish pressure when directly contacting, the pressure between the movable loop 5 and the rubber sheet gasket 2 is smaller, therefore for described
The abrasion of rubber sheet gasket 2 is smaller, until the rubber sheet gasket 2 can just compress, while make institute after being inserted into the Rigid insert panels 6
Fixing piece 3 can thoroughly be fastened by stating nut body 1.
When being inserted into Rigid insert panels 6, if insertion is excessively light, the Rigid insert panels 6 should be taken out, are revolved
After twisting the spacing diminution that the nut body 1 is allowed between the rubber sheet gasket 2, then reinsert the Rigid insert panels 6；?
When being inserted into Rigid insert panels 6, if the gap between the movable loop 5 and the radial exterior protrusion 11 is too small,
Lead to not be inserted into the Rigid insert panels 6, then should screw between the nut body 1 is allowed between the rubber sheet gasket 2
After increase, then reinsert the Rigid insert panels 6.
Preferably, the movable loop 5 is additionally provided with the inwardly protruding portion 51 of diameter, and the inwardly protruding portion 51 of diameter is located at described
Movable loop 5 is towards one end of the rubber sheet gasket 2, and the inwardly protruding portion 51 of the diameter is located at the lantern ring mounting portion 12 and institute
It states between rubber sheet gasket 2.Above structure is conducive to increase contact area between the rubber sheet gasket 2 and the movable loop 5, from
And increase the frictional resistance between the rubber sheet gasket 2 and the movable loop 5, to improve to the spin-ended of the nut body 1
Effect.
Ground is advanced optimized, the Rigid insert panels 6 are C font, and the Rigid insert panels 6 include inserted sheet positive stop end 61 and insert
The thickness of piece tapered end 62, the inserted sheet tapered end 62 is gradually increased by edge to inside.The radial direction exterior protrusion 11 and institute
It states the opposite end face of movable loop 5 and is provided with wedge-shaped indentation portion 63 for cooperating the inserted sheet tapered end 62 to be inserted into.Above-mentioned knot
Structure can be used helper or hammer gently strike convenient for the insertion of the Rigid insert panels 6 when being inserted into Rigid insert panels 6
It hits.
The better embodiment of the utility model is specifically described above, certainly, the utility model can be with
Using form different from the embodiment described above, those skilled in the art institute on the premise of without prejudice to spirit of the invention
The equivalent transformation or corresponding modification of work, all should belong in the protection scope of the utility model.
