Abstract
The utility model relates to machanical fastener technical field, especially relates to a kind of retaining flange nut.Be characterized in comprising hexagon nut, hexagon nut lower end is provided with flange plate, flange plate is provided with and prevents the unidirectional inclined-plane ratchet of own rotation and execute stressed boss to fastening piece.The setting of its unidirectional inclined-plane ratchet, has at least one to engage with the elastic pawl that elastic washer is arranged, and loose-proof flange nut can only be rotated towards a direction, thus reach locking object; The setting of boss, applies pressure to fastening piece, makes unidirectional inclined-plane ratchet engage tightr with the elastic pawl on packing ring.The utility model reasonable in design, structure is simple, and fastening performance is good.
Description
Technical field
The utility model relates to machanical fastener technical field, especially relates to a kind of retaining flange nut.
Background technique
Nut be a kind of be screwed in bolt or screw rod together be used for the part that plays the role of fastening, loosen once fastened object and not knownly just there will be very bad consequence, so prevent nut loosening from being the problem that people study always.The reason of nut loosening has a lot, when sharp pounding, due to repeat varying load or operating temperature higher time, the positive pressure on nut rubbing surface there will be the phenomenon of momentary loss or reduction; Or repeatedly repeat to make the vibration force along nut radial direction impel nut rotation, cause nut loosening.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of retaining flange nut, thus effectively solves the defect existed in prior art.
For achieving the above object, the technological scheme that the utility model is taked is: described retaining flange nut, it is characterized in that comprising hexagon nut, hexagon nut lower end is provided with flange plate, flange plate is also provided with and prevents the unidirectional inclined-plane ratchet of own rotation and execute stressed boss to fastening piece.
Described hexagon nut, flange plate, unidirectional inclined-plane ratchet and boss are formed in one structure.
Described unidirectional inclined-plane ratchet is arranged on flange plate lower end surface or side.
When described unidirectional inclined-plane ratchet is arranged on flange plate lower end surface, radially evenly distributed multiple, the peak of unidirectional inclined-plane ratchet is not higher than boss; It is evenly distributed ringwise when described unidirectional inclined-plane ratchet is arranged on the side of flange plate.
The flank of tooth tilt angle a of described unidirectional inclined-plane ratchet is not more than 90 degree.
The beneficial effects of the utility model are: described retaining flange nut, and the setting of its unidirectional inclined-plane ratchet has at least one to engage with the elastic pawl that elastic washer is arranged, and loose-proof flange nut can only be rotated towards a direction, thus reach locking object; The setting of boss, applies pressure to fastening piece, makes unidirectional inclined-plane ratchet engage tightr with the elastic pawl on packing ring.The utility model reasonable in design, structure is simple, and fastening performance is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model embodiment 1 structural principle schematic diagram;
Fig. 2 is the utility model embodiment 2 structural principle schematic diagram.
Shown in figure: 1. hexagon nut, 2. flange plate, 3. unidirectional inclined-plane ratchet, 4. boss.
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.
Specific embodiment 1, as shown in Figure 1, described retaining flange nut, is characterized in that comprising hexagon nut 1, hexagon nut 1 lower end is provided with flange plate 2, flange plate 2 is also provided with and prevents the unidirectional inclined-plane ratchet 3 of own rotation and execute stressed boss 4 to fastening piece.
Further, described hexagon nut 1, flange plate 2, unidirectional inclined-plane ratchet 3 and boss 4 are formed in one structure.
Further, when described unidirectional inclined-plane ratchet 3 is arranged on flange plate 2 lower end surface, radially evenly distributed multiple, the peak of unidirectional inclined-plane ratchet 3 is not higher than boss; It is evenly distributed ringwise when described unidirectional inclined-plane ratchet 3 is arranged on the side of flange plate 2.
Further, the flank of tooth tilt angle a of described unidirectional inclined-plane ratchet 3 is not more than 90 degree.
Specific embodiment 2, as shown in Figure 2, as different from Example 1, described unidirectional inclined-plane ratchet 3 is arranged on the side of flange plate 2, evenly distributed ringwise.
Described retaining flange nut, during use, loads onto fastener successively, the locking spring washer of anti-rotation and retaining flange nut.Now the locking spring washer of anti-rotation can not rotate.Then rotate retaining flange nut, the elastic pawl of the ratchet of retaining flange nut and the anti-loosening spring washer of anti-rotation is engaged completely, and constitute ratchet mechanism, retaining flange nut just can not rotate in the opposite direction, thus reaches locking object.
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.
Claims (5)
