Description
Technical field
The utility model relates to a kind of fastenings, particularly relates to a kind of Anti-loosening nut.
Background technique
Nut is the part got up by machinery compact siro spinning technology, together with being screwed in, is used for playing the role of fastening by the screw thread of inner side with bolt or screw rod.Nut, as a kind of conventional fastening piece, is widely used in every field.Plain nut can loosen under the various situations such as vibrations, stretching, distortion, rising-heat contracting-cold, corrosion, when nut is applied to roving object, due to long use, nut is also easy to split away off because loosening from bolt, cause product quality problem, cause economic loss.
Also there are some anti-loosing nuts at present, can make to lock and difficult drop-off between bolts and nuts.One is made up of two-part, each part has staggered cam, because temples wedge-type design slope rake angle is greater than the angle of thread of bolt, this combination just tightly be bited into an entirety, when there being vibrations, the mutual changing of the relative positions of nut convex portion, Chen Sheng lifting tension force, thus reach anti-loosening effect; Another kind is attached on screw thread so that special engineering plastics are permanent, is that inner outside thread is tightening process, engineering expect to be extruded and produce powerful reaction force, substantially increase the frictional force between outside thread, provide to vibrations absolute resistance.
The complex structure of the Anti-loosening nut of above-mentioned two kinds of structures, adds processing cost.And locking member can not bear stronger vibrations and larger external force, Applicable scope is narrower, in big machinery, especially do not have good anti-loosening effect.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of Anti-loosening nut.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of Anti-loosening nut, it comprises main body, described main body is prismatic, there is the through hole of an axis in described main center, described main body end face is provided with multiple screw, and described multiple screw is arranged on a wherein limit of described main body end face, described main body is provided with the otch radially across described screw in the side near screw.
Described main body is regular prism shape.Internal thread is provided with in described through hole.Be provided with internal thread in described screw, the degree of depth of screw is greater than the distance of described otch apart from described body upper surface.Described otch is at least switched to described through hole.
The beneficial effects of the utility model are: first, and the outside thread of bolt is when bolt screws in nut, and incision is bitten, and then screws in described multiple screw by multiple screw and tightens, making otch bite the outside thread of described bolt more tightly.Make like this to be subject between nut and bolt larger external force or comparatively strong vibration time, because screw is not released, so otch still tightly bites the outside thread of bolt, cause bolt and Anti-loosening nut relative movement can not occur, reach the effect preventing nut loosening.In addition, the utility model changes without the need to the size to nut or bolt, material, and structure is simple, and production and processing is got up convenient and easy, and applied widely.

Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of Anti-loosening nut, it comprises main body 1, described main body 1 is prismatic, there is the through hole 2 of an axis at described main body 1 center, described main body 1 end face is provided with multiple screw 3, and described multiple screw 3 be arranged on described main body 1 end face wherein, described main body 1 is being provided with the otch 4 radially across described screw 3 near the side of screw 3.
Described main body 1 is regular prism shape.Internal thread is provided with in described through hole 2.Be provided with internal thread in described screw 3, the degree of depth of screw 3 is greater than the distance of described otch 4 apart from described main body 1 upper surface.Described otch 4 is at least switched to described through hole 2 place.
Working procedure of the present utility model: screwed in by the bolt 5 corresponding with described through hole 2 size in main described through hole 2, due to the existence of main body side notched 4, when bolt 5 screws in, the outside thread of described bolt 5 is understood some and is snapped in described otch 4.When bolt 5 is threaded to desired location, get the screw 8 that multiple size is corresponding with described screw 3, described multiple screw 8 to be screwed in respectively in described multiple screws 3 and to tighten.In the process of tightening, described otch 4 can compress by screw 8, so just makes the outside thread incision 4 of bolt 5 tightly bite, thus prevents bolt 5, with described main body 1, relative turn occurs.Even if when being subject to larger external force or shaking between bolt 5 and described main body 1, because described screw 8 can not loosen, what thus still can ensure between described main body 1 and bolt 5 is fastening.When disassembly is desired, only need first multiple screw 8 to be unscrewed or back-outed completely described screw 3, allow described otch 4 unclamp the outside thread of bolt 5, described main body 1 can be disassembled from bolt 5.
Embodiment 1
As shown in Figure 6, Figure 7, a kind of nut loosened is applied on bolt 5, and described main body 1 is positive hexagon, and described main body 1 is provided with two screws 3, and the degree of depth of described otch 4 is switched to 1/2nd places of described main body 1.Screwed in by described bolt 5 in the through hole 2 of described main body 1, due to the existence of main body 1 side notched 4, when bolt 5 screws in, the outside thread of described bolt 5 is understood some and is snapped in described otch 4.When bolt 5 screws with main body 1, bolt 5 can strengthen the tightness with main body 1 under the effect of spring washer 6 and plain cushion 7.Then two pieces of screws 8 to be screwed into respectively in two screws 3 of described main body 1 and fastening good.Make like this to be subject between main body 1 and bolt 5 larger external force or comparatively strong vibration time, because screw 8 is not released, so otch 4 still tightly bites the outside thread of bolt 5, cause bolt 5 and main body 1 relative movement can not occur, reach the effect preventing nut loosening.When disassembly is desired, described screw 3 of only need first two screws 8 being unscrewed or be back-outed completely, allows described otch 4 unclamp the outside thread of bolt 5, described main body 1 can be disassembled from bolt 5.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
