Description
Technical field
The present invention relates to a kind of Hardware fitting field, more particularly to a kind of attaching nut.
Background technology
During the manufacturing of equipment, the rod piece in some frames is up to tens meters, it is therefore desirable to segmental machining, then
Connected with attaching nut.
For current attaching nut mostly using cylindrical structure, middle part processes tapped through hole to realize two bodies of rod
It is connected, but during thread fitting, if ridge is not accurate enough away from processing, gap can be produced between ridge, is coordinated
Easily loosen.
The content of the invention
For above-mentioned technical problem, the purpose of the present invention is：A kind of attaching nut is proposed, is made between ridge
Coordinate the risk close, reduction thread fitting loosens.
What the technical solution of the present invention was realized in：A kind of attaching nut, including nut body, spring and balance
Block；The nut body includes installation end and the connecting pin being connected with installation end, and the installation end is positive hexagonal column；It is described
Connecting pin is cylinder；The installation end and connecting pin are respectively equipped with the screw-threaded counterbore not connected along axle center；The screw thread
Sliding slot is equipped with counterbore side wall；The sliding slot is axially symmetric；The screw-threaded counterbore bottom face is equipped with cylinder boss；It is described
Balance weight is cylinder, is arranged in the screw-threaded counterbore；Convex block is arranged with the balance weight side wall；The convex block and institute
State sliding slot and coordinate movement；The spring one end is connected with the cylinder boss fitting, and the other end is connected with the balance weight end face.
Preferably：Sliding slot in the installation end and connecting pin screw-threaded counterbore is two.
Preferably：The track length and the screw-threaded counterbore deep equality.
Preferably：The convex block is semicircle.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The connection of the present invention
Nut, it is simple in structure, it is easy to use, effectively it can prevent thread fitting from loosening.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is front view sectional view of the present invention；
Fig. 2 is top view of the present invention；
Fig. 3 is the structure diagram of balance weight of the present invention：
Wherein：1st, nut body；11st, installation end；12nd, connecting pin；13rd, screw-threaded counterbore；14th, sliding slot；15th, cylinder boss；
2nd, balance weight；21st, convex block；3rd, spring.
Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings：
As attached drawing 1 to 3 show a kind of attaching nut of the present invention, including nut body 1, spring 3 and balance weight
2；Nut body 1 includes installation end 11 and the connecting pin 12 being connected with installation end 11；Installation end 11 is positive hexagonal column；Connection
End 12 is cylinder；Installation end 11 and connecting pin 12 are respectively equipped with the screw-threaded counterbore 13 not connected along axle center；Two screw threads
The diameter of counterbore 13 can be different according to actual needs；Two axially symmetric cunnings are equipped with two 13 side walls of screw-threaded counterbore
Groove 14；14 length of sliding slot is consistent with the depth of screw-threaded counterbore 12；13 bottom face of screw-threaded counterbore is equipped with cylinder boss 15；Balance weight
2 be cylinder, is arranged in screw-threaded counterbore 13；Convex block 21 is arranged with 2 side wall of balance weight；Convex block 21 coordinates in sliding slot 14
It is mobile；3 one end of spring is connected with 15 fitting of cylinder boss, and the other end is fixedly connected with 2 lower face of balance weight.
In use, screw-threaded counterbore thread fitting of two bodies of rod respectively with installation end and linkage section is connected, the process screwed
In, while promote balance weight to move inward and continuous holddown spring, it is tight that the active force of spring opposite direction can coordinate ridge
Close, inwardly rotating deeper, ridge coordinates closer, and then effectively prevents thread fitting from loosening, and installation end is designed as
Regular hexagon, can make the body of rod rotating more laborsaving.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The connection of the present invention
Nut, it is simple in structure, it is easy to use, effectively it can prevent thread fitting from loosening.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, it is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
