Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 3, the elastic conical surface locking thread structure provided by the utility model comprises a mechanism positioning surface 1, wherein an external thread part 2 is fixedly connected to the left side of the mechanism positioning surface 1, an internal thread part 3 is connected to the surface thread of the external thread part 2, an elastic conical surface thread 4 is fixedly connected to the left side of the internal thread part 3, and the elastic conical surface thread 4 is in threaded connection with the external thread part 2.
Referring to fig. 2, the surface of the elastic conical thread 4 is provided with a plurality of open grooves 5, the open grooves 5 are distributed in an annular equidistant manner, and the diameter of the elastic conical thread 4 is smaller than that of the external thread part 2.
As a technical optimization scheme of the utility model, through arranging the open slot 5 and the elastic conical surface thread 4 with the diameter smaller than that of the external thread part 2, a user can conveniently adjust the pretightening force of the elastic conical surface thread 4 by designing different open slots 5, so that the elastic conical surface thread 4 with the diameter smaller than that of the external thread part 2 can elastically deform due to different diameters when the elastic conical surface thread 4 with the diameter smaller than that of the external thread part 2 is screwed into the external thread part 2.
The working principle and the using flow of the utility model are as follows: by processing the cylindrical thread and the elastic conical thread 4 of the thin-wall open slot 5 on one internal thread part 3, when the internal thread part 3 is assembled, the cylindrical thread part of the internal thread part 3 is screwed into the external thread part 2 inwards, and when the internal thread part is screwed into the elastic conical thread 4, radial pressure is generated because the internal thread diameter of the elastic conical thread 4 is smaller than the diameter of the external thread part 2; at this time, the rotation moment is increased, when the moment is larger than the radial pressure of the elastic conical surface thread 4, the elastic conical surface thread 4 is deformed, the diameter is increased, and the internal thread part 3 is continuously screwed forward; until the screw is screwed on the mechanism positioning surface 1, the screw is elastically deformed by utilizing the conical surface screw of the thin-wall open slot 5 to generate radial pretightening force of the screw, so that the screw is prevented from loosening, the screw connection structure is prevented from loosening, different pretightening forces can be generated according to design requirements by designing the sizes and the opening forms of the screw with different elastic conical surfaces, the fastening structure design used under various working conditions is provided, and the screw locking function can be directly realized by using one part without adding anti-loosening parts or assembling procedures.
The same principle is realized by adopting a screw connection structure and a machine with locking and anti-loose functions, and also by adopting the elastic deformation principle of the conical screw with the thin-wall opening.
An elastic conical surface locking thread structure can be used for a machine which adopts a thread connection structure and needs a locking function.
To sum up: this elastic conical surface locking thread structure through setting up elastic conical surface screw thread 4, makes elastic conical surface screw thread 4 screw thread elastic deformation, produces the radial pretightning force of screw thread, has solved and has had the problem such as needs increase locking part or increase assembly process.
