The rotation that axis body itself can be will drive, drives the separation of nut, so needing to improve the joint place of nut, improves double spiral shells
Female anti-loose effect, and a kind of existing single nut use fastened using wedge shaped washer can effectively improve fastening effect
Fruit improves the anti-loose effect of double nut so design can be combined for wedge shaped washer and double nut.
Utility model content
The purpose of this utility model is to provide a kind of fixed devices of the anti-loose double nut of Steel structure equipment installation axle, with solution
The problem of anti-loose effect of double nut can be improved in existing wedge shaped washer certainly mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions: a kind of Steel structure equipment installation axle is anti-loose
Double nut fixes device, including rack, is equipped with stop nut at the top of the rack, the top one of the stop nut at
Type has the first teeth, and the first wedge groove, the top clamping of first wedge groove are uniformly provided at the top of first teeth
There is a check washer, the two sides up and down of the check washer are connected with tight uniformly integrally formed with voussoir at the top of the voussoir
Gu nut, integrally formed with the second teeth, the bottom of second teeth is uniformly provided with second for the bottom of the fastening nut
Wedge groove is equipped with installation axle in the rack, and stop nut and fastening nut are screwed on the outer ring of installation axle, and described
Check washer is socketed on the outer ring of installation axle.
Preferably, the wedge-shaped gradient of first wedge groove, voussoir and the second wedge groove is greater than the spiral shell in the installation axle
The line gradient.
Preferably, the bottom of the stop nut is uniformly provided with radial small tooth.
Compared with prior art, the utility model has the beneficial effects that the utility model is by the basis of double nut,
Increase the check washer of wedge structure, thus realize that the wedge-shaped gradient is greater than thread gradient, when locking system overload occurs, displacement
Occur at voussoir and wedge groove, formed and improve fastening effect, to realize can be abundant with double nut the advantages of wedge shaped washer
The advantages of fixed axis body structural device, is combined, and improves the fixed function to Steel structure equipment.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 rack, 2 stop nuts, 3 first teeth, 4 first wedge grooves, 5 check washers, 6 voussoirs, 7 fastening nuts,
8 second teeth, 9 second wedge grooves, 10 installation axles.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of anti-loose double nut of Steel structure equipment installation axle
Fixed device, including rack 1, the top of the rack 1 are equipped with stop nut 2, and stop nut 2 is used to be fixed on rack 1,
It realizes and installation axle 10 is fixed, bearing block is installed on the outer wall of installation axle 10, and stop nut 2 is fixed on the outer ring of bearing block
On, integrally formed with the first teeth 3, the top of first teeth 3 is uniformly provided with first wedge at the top of the stop nut 2
Shape slot 4, the top of first wedge groove 4 are connected with check washer 5, the uniform one in the two sides up and down of the check washer 5
Voussoir 6 is formed, the top of the voussoir 6 is connected with fastening nut 7, and the bottom of the fastening nut 7 is integrally formed with second
Teeth 8, the bottom of second teeth 8 are uniformly provided with the second wedge groove 9, realize and prevent what existing double-wedge washer formed
It loosens washer to improve on stop nut 2 and fastening nut 7, realizes that the wedge shape of joint face is fixed, installed in the rack 1
There is installation axle 10, and stop nut 2 and fastening nut 7 are screwed on the outer ring of installation axle 10, and the check washer 5 is socketed in
On the outer ring of installation axle 10, the bearing for the screw thread that matches with stop nut 2 and fastening nut 7 is installed on the outer ring of installation axle 10
Sleeve, for guaranteeing fixing and do not interfere with loosening for nut to installation axle 10.
Wherein, the wedge-shaped gradient of first wedge groove 4, voussoir 6 and the second wedge groove 9 is greater than in the installation axle 10
