Abstract
The utility model discloses a connecting bolt which employs a reverse nut to lock, reverse external threads which are smaller than the diameter of main body threads are arranged on a threaded end of the connecting bolt, and an appropriate reverse nut is arranged correspondingly. When the connecting bolt of the utility model is unlocked in dynamic operation, a connecting nut is screwed out along with the connecting bolt, but the screwing out direction of the connecting nut is the fastening direction of the reverse lock nut, thereby the unlocking of the connecting bolt is limited.
Description
Technical field
The utility model relates to a kind of bolt, specifically utilizes the connecting bolt of reverse nut anti-looseness.
Background technique
When general textbook was told about screw retention, the technical measures of recommendation had that double nut loosens, spline iron is locking, cotter pin is locking etc., and these traditional locking measures cut both ways: the pairs of anti-loose nut measure is simple but unreliable, withdraws from the attaching nut sometimes; All the other anti-loose method technology are comparatively complicated, and operation is not simple and direct, inconvenient when needing loose nut.
The model utility content
Technical problem to be solved of the present utility model is at the prior art deficiency, and a kind of connecting bolt that utilizes reverse nut anti-looseness is provided, and realizes its function by the stopping of reverse nut of bolt end setting, realizes easily convenient disassembly.
The technological scheme that its technical problem that solves the utility model adopts is: utilize the connecting bolt of reverse nut anti-looseness, in the threaded end setting of bolt less than the derotation of the main body diameter of thread to outside thread, corresponding equipped suitable reverse nut.
The external diameter of described reverse nut is greater than the internal diameter of main body nut.
The connecting bolt of the reverse nut anti-looseness of utilization of the present utility model compared with prior art has following beneficial effect:
The connecting bolt of the reverse nut anti-looseness of utilization of the present utility model plays the plain bolt that remains of interconnect function.And the derotation that minor diameter is set in the termination of these bolts is to outside thread, corresponding equipped suitable nut.Like this, when connecting bolt occurred becoming flexible in dynamic duty, the attaching nut can withdraw from thereupon; And the rotation direction that the attaching nut withdraws from but is the fastening direction of reverse lock nut, so loosening just the obtaining of connecting bolt restrained.
Description of drawings
Accompanying drawing 1 is the structural representation that utilizes the connecting bolt of reverse nut anti-looseness.
Among the figure: 1, bolt; 2, main body nut; 3, reverse nut.
Embodiment
Next explain below with reference to Figure of description the connecting bolt of the reverse nut anti-looseness of utilization of the present utility model being done.
The connecting bolt of the reverse nut anti-looseness of utilization of the present utility model, in the threaded end setting of bolt 1 less than the derotation of the main body diameter of thread to outside thread, corresponding equipped suitable reverse nut 3.
The external diameter of described reverse nut is greater than the internal diameter of main body nut 2.
After common connecting bolt screws, derotation is screwed on to nut, derotation abuts against with the attaching nut to nut, when the attaching nut had loosening trend desire to screw out, derotation near thereon, obtained a fastening torsion to the nut head, because the attaching nut keeps out, screw-in can not be realized.So the attaching nut can not withdraw from and derotation also can not be fastening to nut, plays locking effect safe against all possibilities.
The connecting bolt of the reverse nut anti-looseness of utilization of the present utility model plays the plain bolt that remains of interconnect function.And the derotation that minor diameter is set in the termination of these bolts is to outside thread, corresponding equipped suitable nut.Like this, when connecting bolt occurred becoming flexible in dynamic duty, the attaching nut can withdraw from thereupon; And the rotation direction that the attaching nut withdraws from but is the fastening direction of reverse lock nut, so loosening just the obtaining of connecting bolt restrained.
Claims (2)
1, utilize the connecting bolt of reverse nut anti-looseness, it is characterized in that: in the threaded end setting of bolt less than the derotation of the main body diameter of thread to outside thread, corresponding equipped suitable reverse nut.
2, the connecting bolt of the reverse nut anti-looseness of utilization according to claim 1, it is characterized in that: the external diameter of described reverse nut is greater than the internal diameter of main body nut.
