Abstract
The utility model discloses a kind of Anti-loosening nut linkage structure, comprise link and the screw rod through link, screw rod screws nut link is fastening, a locking lasso is socketed outside described nut, be provided with anti-rotational structure between described locking lasso and link, described anti-rotational structure comprises the deep gouge that on link, corresponding described nut is arranged, and nut screws rear bottom and is located in deep gouge, locking lasso outer ring is provided with dop, and described deep gouge madial wall is provided with the draw-in groove snapped in for dop.The utility model structure is simple, and anti-loosening performance is good.
Description
Technical field
The utility model relates to fastening piece linkage structure, particularly relates to a kind of Anti-loosening nut linkage structure.
Background technique
Have vibration to produce during common mechanical machine operation, this not only consumes a part of power, waste energy, vibrate simultaneously and each connected element also can be caused to produce loosening phenomenon, especially at the position that nut bolt connects, once occur that nut loosening just has the possibility come off, accident is caused to produce.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of Anti-loosening nut linkage structure, and structure is simple, and anti-loosening performance is good.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of Anti-loosening nut linkage structure, comprise link and the screw rod through link, screw rod screws nut link is fastening, it is characterized in that: outside described nut, be socketed a locking lasso, anti-rotational structure is provided with between described locking lasso and link, described anti-rotational structure comprises the deep gouge that on link, corresponding described nut is arranged, nut screws rear bottom and is located in deep gouge, locking lasso outer ring is provided with dop, and described deep gouge madial wall is provided with the draw-in groove snapped in for dop.
As preferably, described locking lasso is ring, and locking lasso inner ring is the regular hexagon structure with nut screw connection, and described dop is provided with four and is uniformly distributed on lasso outer ring.
As preferably, described locking lasso height is less than the height of deep gouge.
As preferably, described dop is triangle, trapezoidal or square.
The utility model adds a locking lasso, and be provided with anti-rotational structure between locking lasso and link, like this, because locking lasso inner ring is the regular hexagon structure with nut screw connection, locking lasso inner ring can not rotate relatively with between nut, and simultaneously anti-rotational structure prevents that locking lasso is relative with link to be rotated, loosening after thus can preventing fastening nuts, structure is simple, and anti-loosening performance is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, for the embodiment of a kind of Anti-loosening nut linkage structure of the utility model, comprise link 2 and the screw rod 21 through link, screw rod 21 screws nut 3 by fastening for link 2, be socketed a locking lasso 1 outside described nut 3, between described locking lasso 1 and link 2, be provided with anti-rotational structure.
Concrete, described anti-rotational structure comprises the deep gouge 20 that on link 2, corresponding described nut 3 is arranged, and nut screws rear bottom and is located in deep gouge, and locking lasso 1 outer ring is provided with dop 11, and described deep gouge madial wall is provided with the draw-in groove 22 snapped in for dop.Described locking lasso is ring, and locking lasso inner ring is the regular hexagon structure 10 with nut screw connection, and described dop is provided with four and is uniformly distributed on lasso outer ring.Described locking lasso height is less than the height of deep gouge.Described dop is triangle, trapezoidal or square.
To screw on nut 3, nut 3 screws rear bottom and is located in deep gouge 20, is then positioned in deep gouge by locking lasso 1, and wherein locking lasso inner ring is socketed on outside nut, the dop 11 of locking lasso outer ring snaps in the draw-in groove 22 of deep gouge madial wall, locking lasso and be interference fit between nut and deep gouge.Owing to adding a locking lasso, and be provided with anti-rotational structure between locking lasso and link, like this, because locking lasso inner ring is the regular hexagon structure with nut screw connection, locking lasso inner ring can not rotate relatively with between nut, and simultaneously anti-rotational structure prevents that locking lasso is relative with link to be rotated, loosening after thus can preventing fastening nuts, structure is simple, and anti-loosening performance is good.
Claims (4)
