Abstract
The utility model relates to machanical fastener technical field, especially relates to a kind of retaining flange bolt.Be characterized in comprising screw rod, described screw rod upper end is provided with flange nut, and described flange nut comprises nut and flange plate, flange plate is also provided with unidirectional inclined-plane ratchet and executes 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 locking flange bolt 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 bolt.
Background technique
A lot of object needs to use bolt in daily life, nut is fastenedly connected.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.Locking the name of the game is exactly prevent relatively rotating of screw pair.Locking method is a lot, has that friction is locking, machinery is locking, forever locking etc.Different positions is used for according to its advantage.But the locking problem at some position is not still so well solved till now.
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 bolt, thus effectively solves the defect existed in prior art.
6. for achieving the above object, the technological scheme that the utility model is taked is: described retaining flange bolt, be characterized in comprising screw rod, described screw rod upper end is provided with flange nut, described flange nut comprises nut and flange plate, flange plate is also provided with unidirectional inclined-plane ratchet and executes stressed boss to fastening piece.
Described screw rod and flange nut are formed in one structure.
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.
When described unidirectional inclined-plane ratchet is arranged on the side of flange plate, evenly distributed ringwise.
Described unidirectional inclined-plane ratchet tooth face tilt angle a is not more than 90 degree.
The beneficial effects of the utility model are: described retaining flange bolt, 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 locking flange bolt 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. screw rod, 2. flange nut, 3. nut, 4. flange plate, 5. unidirectional inclined-plane ratchet.
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, described retaining flange bolt, is characterized in comprising screw rod 1, and described screw rod 1 upper end is provided with flange nut 2, described flange nut 2 comprises nut 3 and flange plate 4, flange plate 4 is also provided with unidirectional inclined-plane ratchet 5 and executes stressed boss 6 to fastening piece.
Further, described screw rod 1 and flange nut 2 are formed in one structure.
Further, when described unidirectional inclined-plane ratchet 5 is arranged on flange plate 4 lower end surface, radially evenly distributed multiple, the peak of unidirectional inclined-plane ratchet 5 is not higher than boss; When described unidirectional inclined-plane ratchet 5 is arranged on the side of flange plate 4, evenly distributed ringwise.
Further, described unidirectional inclined-plane ratchet 5 flank of tooth tilt angle a is not more than 90 degree.
Specific embodiment 2, as shown in Figure 2, as different from Example 1, described unidirectional inclined-plane ratchet 5 is arranged on the side of flange plate 4, evenly distributed ringwise.
Described retaining flange bolt, during use, loads onto fastener successively, the locking spring washer of anti-rotation and retaining flange bolt.Now the locking spring washer of anti-rotation can not rotate.Then rotate retaining flange bolt, the elastic pawl of the ratchet of retaining flange bolt and the locking spring washer of anti-rotation is engaged completely, and constitute ratchet mechanism, retaining flange bolt 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)
