Abstract
The utility model discloses a self-locking plate nut with a nylon insert. The self-locking plate nut comprises a nut (1), wherein an annular groove (3) is formed in the thread (2) of the nut (1); and a nylon ring (4) is arranged in the annular groove (3). According to the utility model, The changes of the low-strength self-locking plate nut with the nylon insert lie in that a circular grove is formed at the original convergent end, and the nylon ring of which the inside diameter is slightly smaller than the intermediate diameter of the thread is embedded into the annular groove, so that the problem that the locking moment of the low-strength all-metal splint self-locking nut is unstable is solved. Because the self-locking moment of the splint nylon insert self-locking nut is mainly generated by the nylon ring of which the inside diameter is slightly smaller than the intermediate diameter of the thread, the requirement on the strength of the splint nut is not very high and the manufacturing cost is low. The splint nylon insert self-locking nut is suitable for the industries of aviation, aerospace and electronics.
Description
Technical field
The utility model relates to a kind of supporting plate nylon inserts self-locking nut, belongs to technical field of fastening.
Background technique
Find that in production testing and even user existing full-metallic supporting plate self-lock nut is unstable to low intensive supporting plate locking torque when using supporting plate self-lock nut.Mainly be screw thread and the bolt at the locking position of full-metallic supporting plate self-lock nut when screwing, receive the extruding of bolt thread and restore to the original state, thereby make nut produce resiliently deformable and elastic deformation force.By the interference effect of elastic deformation force, produce the friction torque that stops rotation to bolt thread.The performance of whole metal self-locking nut depends on the elasticity of nut body material.Because the low-intensity nut makes its non-round closing in position produce plastic deformation when being screwed into bolt easily, is difficult to guarantee the performance requirement of elasticity locking, so whole metal self-locking nut only is suitable for high-intensity nut.The operating temperature of full-metallic supporting plate self-lock nut receives the restriction of nut material and coating.
The model utility content
The purpose of the utility model is, a kind of supporting plate nylon inserts self-locking nut is provided, and solves low-intensity self-locking nut locking torque problem of unstable.To overcome the deficiency of existing technology.
The technological scheme of the utility model:
A kind of supporting plate nylon inserts self-locking nut comprises nut, and the screw thread of nut is provided with annular groove, is provided with nylon ring in the annular groove.
In the aforementioned supporting plate nylon inserts self-locking nut, the said nut that is provided with nylon ring one end is provided with closing in.
In the aforementioned supporting plate nylon inserts self-locking nut, the internal diameter of said nylon ring is less than the middle footpath of internal thread on the nut, and greater than the footpath, the end of internal thread on the nut.
In the aforementioned supporting plate nylon inserts self-locking nut, said nut is provided with supporting plate, and supporting plate is provided with fixed hole.
In the aforementioned supporting plate nylon inserts self-locking nut, said supporting plate is located at nut one side, or is provided with in the nut bilateral symmetry.
In the aforementioned supporting plate nylon inserts self-locking nut, said nut is the awl cylinder, and its tapering is 3~6 degree.
In the aforementioned supporting plate nylon inserts self-locking nut, said nut is ML18 low carbon steel, ML25 low carbon steel, LY11 aluminum alloy or Hpb59-1 Cuprum alloy low-intensity material goods.
In the aforementioned supporting plate nylon inserts self-locking nut, said nylon ring is 1010 nylon or 66 nylon products.
Compared with prior art; The utility model is through changing low intensive supporting plate self-lock nut at annular groove of former closing in end processing; In annular groove, inlay the nylon ring that an internal diameter is slightly smaller than effective diameter of thread, solved the locking torque problem of unstable of low intensive full-metallic supporting plate self-lock nut.Because the main inner footpath of self-locking moment of the utility model is slightly smaller than the nylon ring of warp in the screw thread and produces, so the intensity of plate nut is not had very high requirement, low cost of manufacture.Be applicable to aviation, space flight and electron trade.

Fig. 3 is the structural representation of single mount plate;
Fig. 4 is the side view of Fig. 3.
Being labeled as in the accompanying drawing: the 1-nut, the 2-screw thread, the 3-annular groove, the 4-nylon ring, 5-closes up, 6-supporting plate, 7-fixed hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify, but not as any restriction to the utility model.
Embodiment.A kind of supporting plate nylon inserts self-locking nut comprises nut 1, and nut 1 adopts low-intensity materials such as ML18 low carbon steel, ML25 low carbon steel, LY11 aluminum alloy or Hpb59-1 Cuprum alloy to process.The screw thread 2 of nut 1 is provided with annular groove 3, is provided with nylon ring 4 in the annular groove 3.Nylon ring 4 adopts 1010 nylon or 66 nylon elastomeric material to process.The nut 1 of nylon ring 4 one ends is provided with and closes up 5.The internal diameter of nylon ring 4 is less than the middle footpath of internal thread on the nut, and greater than the footpath, the end of internal thread on the nut.Said nut 1 is provided with supporting plate 6, and supporting plate 6 is provided with fixed hole 7.Supporting plate 6 is located at nut 1 one sides, constitutes single mount crab bolt (seeing Fig. 3 and 4).Or supporting plate 6 is set in nut 1 bilateral symmetry, constitute double bracket crab bolt (seeing Fig. 1 and 2).Said nut 1 is the awl cylinder, and its tapering is 3~6 degree.
Self-lock mechanism with the utility model
The utility model is that the upper end of low-intensity nylon self-locking nut is inlayed and adorned a nylon ring that internal diameter is slightly littler than effective diameter of thread, and is as shown in Figure 1.When adapted bolt and extruding nylon ring after nylon ring contacts, nylon ring is squeezed out screw thread, the screw thread on the bolt tightly " is embraced ".Because the effect of this interference fit forms the friction torque that stops screw thread rotation, thereby makes nut have the self-locking locking functions.The friction torque of the utility model comes from nylon ring, and its locking property depends primarily on the material and the size of nylon ring.The nylon ring material has good toughness, elasticity and wear resistance, can absorb the external shock vibration effectively, and good recoverability and reusability are arranged.So the locking property of this nut is more much better than full-metallic supporting plate self-lock nut, very high locking reliability is arranged.Because its locking property and nut body material are irrelevant, more are widely used in the lower supporting plate self-lock nut of strength grade, and be also not high to externally threaded required precision.Nylon ring material commonly used has nylon 1010 and nylon 66.In order to prolong the aging life-span of nylon material, can in material, add antiager.
