Abstract
The utility model discloses a connecting bolt which employs reverse threads to lock, a reverse threaded hole which is smaller that the diameter of main body threads is arranged on a threaded end of the connecting bolt, and an appropriate reverse auxiliary bolt is arranged correspondingly. Under the premise of sufficiently checking strength, the end of the connecting bolt is equipped with the reverse threaded hole with small diameter, and is correspondingly equipped with the appropriate bolt, thereby when the connecting bolt is unlocked in dynamic operation and a nut is about to be screwed out automatically, the screwing out direction of the nut is the fastening direction of the reverse lock bolt, and then, the unlocking of the connecting bolt is limited.
Description
Technical field
The utility model relates to a kind of bolt, specifically utilizes the locking connecting bolt of reverse thread.
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 locking connecting bolt of reverse thread that utilizes is provided, and realizes its function by the stopping of reverse secondary bolt of bolt end setting, realizes easily convenient disassembly.
The technological scheme that its technical problem that solves the utility model adopts is: utilize the locking connecting bolt of reverse thread, in the threaded end setting of bolt less than the derotation of the main body diameter of thread to tapped hole, corresponding equipped suitable reverse secondary bolt.
The retaining platform external diameter of described reverse secondary bolt is greater than the internal diameter of main body nut.
The locking connecting bolt of reverse thread that utilizes of the present utility model compared with prior art has following beneficial effect:
Under the prerequisite of fully checking intensity, the termination of connecting bolt minor diameter is set derotation to screw, corresponding equipped suitable bolt.Like this, connecting bolt dynamic duty occur loosening, when nut is desired to withdraw from automatically; The rotation direction that it withdraws from but is the fastening direction of reverse chek bolt, so loosening just the obtaining of connecting bolt restrained.
Description of drawings
Accompanying drawing 1 is for utilizing the structural representation of the locking connecting bolt of reverse thread.
Among the figure: 1, bolt; 2, main body nut; 3, reverse secondary bolt.
Embodiment
Next with reference to Figure of description the locking connecting bolt of reverse thread that utilizes of the present utility model is explained below doing.
The locking connecting bolt of reverse thread that utilizes 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 tapped hole, corresponding equipped suitable reverse secondary bolt 3.
The retaining platform external diameter of described reverse secondary bolt is greater than the internal diameter of main body nut 2.
After common connecting bolt screws, derotation is screwed in to bolt, derotation abuts against with the attaching nut to bolt head, when the trend desire that occurs becoming flexible as the attaching nut screwed out, derotation near thereon, obtained a fastening torsion to bolt head, but owing to keeping out of attaching nut, screw-in can not be realized.So with regard to occurring that the attaching nut can not withdraw from and derotation to bolt can not be fastening situation, play locking effect safe against all possibilities.
Under the prerequisite of fully checking intensity, the termination of connecting bolt minor diameter is set derotation to screw, corresponding equipped suitable bolt.Like this, connecting bolt dynamic duty occur loosening, when nut is desired to withdraw from automatically; The rotation direction that it withdraws from but is the fastening direction of reverse chek bolt, so loosening just the obtaining of connecting bolt restrained.
Claims (2)
1, utilize the locking connecting bolt of reverse thread, it is characterized in that: in the threaded end setting of bolt less than the derotation of the main body diameter of thread to tapped hole, corresponding equipped suitable reverse secondary bolt.
2, the locking connecting bolt of reverse thread that utilizes according to claim 1, it is characterized in that: the retaining platform external diameter of described reverse secondary bolt is greater than the internal diameter of main body nut.
