Abstract
The utility model provides a locking nut, comprising a nut body and threads, wherein the threads are formed in the inner wall of the nut body; a plurality of limiting grooves are formed in the parts, close to the left end of the nut body, of the threads; the limiting grooves are of a semi-circular structure respectively. The locking nut has the advantages of stability in rotational connection, convenience in operation, high working efficiency, rational design, simple structure, simplicity in manufacture and the like.
Description
Technical field
The utility model relates to universal accessories field, is specifically related to locking nut.
Background technique
The working principle of nut is to adopt the frictional force between nuts and bolt to carry out self-locking, but the reliability of this self-locking will reduce in dynamic load, in some important occasions, we will take some locking measures, guarantee the reliability of nut check, locking nut is exactly the locking measure of one wherein, and the anti-loosing effect quality of locking nut depends primarily on interaction force between nut and bolt thread engagement.
Summary of the invention
Technical problem to be solved in the utility model is to provide locking nut, reasonable in design, simple in structure, manufacture easy, can make nut spin stable, avoid nut in use especially in dynamic load process, to become flexible, operation is simultaneously convenient, and installment work efficiency is high.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: locking nut, comprise nut body, be located at the screw thread on the inwall of nut body, on described screw thread and near the left end of nut body, be provided with some limited impressions, described limited impression adopts semicircular structure.
As preferably, described limited impression adopts four, and uniform ring is located on the inwall of nut body, thereby multiple sockets are provided, and the operation that plug is inserted is more convenient.
As preferably, the height of described limited impression adopt nut body height 1/3rd, thereby can avoid plug to deviate from, make tightened-up structure more stable.
As preferably, the left end end face of described nut body is provided with tank filler sleeve, and described tank filler sleeve communicates with screw thread, thereby can easily lubricate nut body, and the operation that makes to spin is more convenient.
As preferably, the left end end face of described nut body is provided with plug mechanism, comprise retaining ring on the left end end face that is welded on nut body, be connected to iron wire on retaining ring, be fixed on the plug on iron wire, during use, plug is directly inserted to the object that can reach locking in limited impression, integrated design makes fitting operation more convenient, has greatly improved working efficiency.
Beneficial effect:
The locking nut that provides of technique scheme is provided the utility model, reasonable in design, simple in structure, manufacture easy, can make nut spin stable, avoided nut in use especially in dynamic load process, to become flexible, operation is simultaneously convenient, and installment work efficiency is high.
