The novel flange nut comprises a nut main body, wherein a nut seat is arranged at the end part of the nut main body, a threaded hole is coaxially formed in the middle of the nut main body and the nut seat in a penetrating manner, the nut main body is connected with a stud through the threaded hole, a step groove communicated with the threaded hole is axially formed in the bottom of the nut seat, a tightening element used for forming axial elastic compression force on the stud is arranged in the step groove, the tightening element comprises a tightening ring, annular arc grooves are formed in the bottom of the tightening ring inwards, positioning portions and tightening portions are respectively formed in two sides of the tightening ring through the annular arc grooves, an inner ring of the tightening portion extends out of the nut seat to be in contact with the stud, and the tightening element is made of rubber materials. The utility model has the advantage of enhancing the fastening force between the stud and the screw.
Description
Technical Field
The utility model belongs to the technical field of nuts, and relates to a nut, in particular to a novel flange nut.
Background
At present, when the flange nut is applied to an environment with stronger vibration sense, the connection stability of the flange nut and a screw column can be reduced, the flange nut is easy to fall off after a long time, the use of corresponding products is affected, and sometimes accidents are caused even because of looseness of the nut.
Disclosure of Invention
The present utility model has been made keeping in mind the above problems occurring in the prior art, and an object of the present utility model is to provide a novel flange nut having a reinforced nut tightening force.
The aim of the utility model can be achieved by the following technical scheme: the novel flange nut comprises a nut main body, wherein a nut seat is arranged at the end part of the nut main body, a threaded hole is coaxially formed in the middle of the nut main body and the nut seat in a penetrating manner, and the nut main body is connected with a stud through the threaded hole.
In the novel flange nut, a plurality of inner convex lips are arranged at the inner ring of the tightening part.
In the novel flange nut, the top of the tightening part is provided with the clamping ring which is axially and outwards arranged and is clamped with the nut seat.
Compared with the prior art, the novel flange nut has the advantage of enhancing the fastening force between the flange nut and the stud.

Fig. 1 is a schematic perspective view of the novel flange nut.
FIG. 2 is a schematic cross-sectional view of the novel flange nut.
In the figure, 1, a nut main body; 2. a nut seat; 3. a threaded hole; 4. a tightening ring; 5. an annular arc-shaped groove; 6. a positioning part; 7. a tightening part; 8. an inner lip; 9. and (5) clamping the ring.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, the novel flange nut comprises a nut main body 1, wherein the end part of the nut main body 1 is provided with a nut seat 2, threaded holes 3 are coaxially and penetratingly formed in the middle parts of the nut main body 1 and the nut seat 2, the threaded holes 3 are connected with a stud, a step groove communicated with the threaded holes 3 is axially formed in the bottom of the nut seat 2, a tightening element used for forming axial elastic compression force on the stud is installed in the step groove, the tightening element comprises a tightening ring 4, an annular arc groove 5 is formed in the bottom of the tightening ring 4 inwards, two sides of the tightening ring 4 are respectively formed into a positioning part 6 and a tightening part 7 through the annular arc groove 5, a small part of the inner ring of the tightening part 7 extends out of the nut seat 2 and is used for being contacted with the stud, the tightening element is made of rubber materials, when the stud is screwed into the threaded holes 3 and is tightly matched with the threaded holes 3, the lower end part of the tightening part 7 deforms towards the annular arc groove 5, and a tightening area contacted with the stud is formed at the inner ring of the tightening part 7; the screw bolt is screwed down, the lower end part of the tightening part 7 can be outwards expanded towards the annular arc groove 5 due to the screw bolt screwing down, so that a tightening area at the upper end part of the tightening part 7 can be abutted against the surface of the screw bolt to form a pressing effect, and the connection fastening force of the screw bolt is enhanced.
Further, the inner ring of the tightening part 7 is provided with a plurality of inner convex lips 8, so that the contact strength between the tightening part and the stud is enhanced.
Further, the top of the tightening part 7 is provided with an engaging ring 9 which is axially outward and is engaged with the nut seat 2, the nut seat 2 is provided with an engaging groove, and before use, the engaging ring 9 is engaged into the engaging groove to position the tightening element.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although terms such as the nut body 1, the nut seat 2, the screw hole 3, the tightening ring 4, the annular arc groove 5, the positioning portion 6, the tightening portion 7, the inner lip 8, the engaging ring 9 are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
