Abstract
The utility model relates to a kind of Novel anti-loosening nut.Comprise the sub-nut of frustum (1) and be arranged on the sub-nut of taper hole (2) of the sub-nut of frustum (1) lower end; The sub-nut of described frustum (1) lower end outer surface is designed to junction surface on reverse frustoconic (11); The sub-nut of described taper hole (2) upper end internal surface arranges reverse frustoconic endoporus (21), described endoporus (21) side (211) and described upper junction surface (11) correspondence are arranged, and the sub-nut of described frustum (1) lower surface is to being located on endoporus (21) lower surface (212).The utility model is compressed mutually by the taper hole frustum face on two nuts, precision-fit thus produce larger, stiction reliably, realizes nut anti-looseness by this frictional force.
Description
Technical field
The utility model relates to a kind of locknut, particularly a kind ofly lockingly requires high, quick detachable, reusable, non-maintaining nut.
Background technique
In prior art, be generally adopt the lock nut of band nylon ring type, locking glue or use slotted nut to add cotter pin to realize nut anti-looseness; It dismantles inconvenience, and in use easily produces loosening, and not reproducible use, therefore needs to be improved further.
Model utility content
The purpose of this utility model is to provide a kind of locknut, do not adopt locking glue, slotted nut adds cotter pin and the conventional method such as nylon lock nut, and adopting two to have tapering to become a nut locking to realize to the nut combinations of nibbling each other, it has that anti-loosing effect is good, convenient disassembly, reusable and non-maintaining feature to compare common lock nut and nut anti-looseness mode.
The technical solution adopted in the utility model is for this reason: the utility model comprises the sub-nut of frustum (1) and is arranged on the sub-nut of taper hole (2) of the sub-nut of frustum (1) lower end;
The sub-nut of described frustum (1) lower end outer surface is designed to junction surface on reverse frustoconic (11);
The sub-nut of described taper hole (2) upper end internal surface arranges reverse frustoconic endoporus (21), described endoporus (21) side (211) and described upper junction surface (11) correspondence are arranged, and the sub-nut of described frustum (1) lower surface is to being located on endoporus (21) lower surface (212).
The sub-nut of described frustum (1) upper end outer surface is cylndrical surface (12), form the horizontally disposed junction surface (13) of transition between described cylndrical surface (12) and upper junction surface (11), described junction surface (13) is to being located on the sub-nut of taper hole (2) upper surface (22).
The tapering of described endoporus (21) side and lower junction surface (11) is equal, and length is equal.
A kind of connecting means of locknut, carry out according to following steps, first by sub-for taper hole nut (2) according to endoporus (21) state normal mounting upward on bolt (3), again sub-for frustum nut (1) is screwed in bolt (3), and upper junction surface (11) is screwed in endoporus (21) makes the sub-nut of frustum (1) and the sub-nut of taper hole (2) formation drive fit; Until the sub-nut of frustum (1) lower surface is to being located on endoporus (21) lower surface (212).
To the utility model has the advantages that: the utility model is compressed mutually by the taper hole frustum face on two nuts, precision-fit thus produce larger, stiction reliably, realize nut anti-looseness by this frictional force.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is I enlarged view in Fig. 1.
1 be the sub-nut of frustum, 2 be the sub-nut of taper hole in figure, 3 for bolt;
11 be upper junction surface, 12 be cylndrical surface, 13 for junction surface;
21 be endoporus, 22 be upper surface, 211 be side, 212 for lower surface.
Embodiment
The utility model comprises the sub-nut of frustum 1 and is arranged on the sub-nut 2 of taper hole of frustum nut 1 lower end;
Described frustum nut 1 lower end outer surface is designed to junction surface 11 on reverse frustoconic;
Described taper hole nut 2 upper end internal surface arranges reverse frustoconic endoporus 21, and described endoporus 21 side 211 and described upper junction surface 11 correspondence are arranged, and described frustum nut 1 lower surface is to being located on endoporus 21 lower surface 212.
Described frustum nut 1 upper end outer surface is cylndrical surface 12, forms the horizontally disposed junction surface 13 of transition between described cylndrical surface 12 and upper junction surface 11, and described junction surface 13 is to being located on taper hole nut 2 upper surface 22.
The tapering of described endoporus 21 side and lower junction surface 11 is equal, and length is equal.
A kind of connecting means of locknut, carry out according to following steps, first by sub-for taper hole nut 2 according to endoporus 21 state normal mounting upward on bolt 3, again sub-for frustum nut 1 is screwed in bolt 3, and upper junction surface 11 is screwed in endoporus 21 makes the sub-nut of frustum 1 and the sub-nut 2 of taper hole form drive fit; Until frustum nut 1 lower surface is to being located on endoporus 21 lower surface 212.
Working principle of the present utility model is: the utility model two nuts mutually firmly and tight time bolt 3 elongate, thus great axial pressure is produced on the joint conical surface of two nuts, also create larger stiction while that two nuts engaging on the conical surface and achieve screw-threaded coupling, nut anti-looseness.
The utility model by sub-for frustum nut 1 lower surface to being located on endoporus 21 lower surface 212, junction surface 13 is to being located on taper hole nut 2 upper surface 22, the sub-nut of such frustum 1 can closely to being located on the sub-nut 2 of taper hole, prevent both from relative play occurring in the course of the work, further ensure the stability of both work.
