Abstract
The invention discloses a single screw rotation-prevention locking structure which comprises a fastened piece, a retainer and a screw, wherein a boss is arranged on the fastened piece, a counter bore is formed in the retainer, the boss is non-cylindrical, a threaded hole is formed in the boss, and the shape of the counter bore is similar to the shape of the boss. The boss is inserted into the counter bore, and the screw penetrates through the counter bore, enters the threaded hole in the boss, and fixes the retainer and the fastened piece. According to the single screw rotation-prevention locking structure, when the boss is inserted into the counter bore, and the screw penetrates through the counter bore, enters the threaded hole in the boss, and fixes the retainer and the fastened piece, due to the facts that the boss is non-cylindrical, and the shape of the counter bore is similar to the shape of the boss, the retainer is incapable of rotating around the screw, relative rotation between the retainer and the fastened piece is avoided.
Description
Technical field
The present invention relates to a kind of improvement of locking structure, refer in particular to the anti-rotation locking structure of a kind of single screw.
Background technique
In prior art, prevent that the rotation of a part from often needing plural screw locking or adding that pin comes the rotation of limit feature.In prior art, component are many, and processing, installation procedure is many, and cost is high.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, component are few, processing, install simple, the anti-rotation locking structure of the single screw that cost is low.
For achieving the above object, the technical solution used in the present invention is: the anti-rotation locking structure of a kind of single screw comprises fastener, retainer, screw; Be provided with boss on described fastener; Be provided with counter sink on described retainer; Described boss is non-cylindrical; Be provided with tapped hole on described boss; Described counter sink is similar to the shape of boss; Described boss inserts in counter sink, and described screw passes counter sink and enters in tapped hole on boss retainer and fastener are fixed.
Preferably, the cross section of described boss is triangle.
Preferably, the cross section of described boss is polygonal.
Preferably, the cross section of described boss is oval.
Preferably, the cross section of described boss is non-circular shape regularly.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The anti-rotation locking structure of the described single screw of the present invention program, when described boss inserts in counter sink, when described screw passes counter sink and enters in tapped hole on boss retainer and fastener fixedly, because described boss is non-cylindrical, described counter sink is similar to the shape of boss, retainer can not rotate around screw like this, thereby can prevent relatively rotating of retainer and fastener.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the partial sectional view of the anti-rotation locking structure of a kind of single screw of the present invention;
Accompanying drawing 2 is the plan view of accompanying drawing 1;
Wherein: 1, fastener; 2, retainer; 3, screw; 4, boss.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-2 is the anti-rotation locking structure of a kind of single screw of the present invention, comprises fastener 1, retainer 2, screw 3; Be provided with boss 4 on described fastener 1; Be provided with counter sink (not marking) on described retainer 2; Described boss 4 is non-cylindrical; Be provided with tapped hole (not marking) on described boss 4; Described counter sink is similar to the shape of boss 4; Described boss 4 inserts in counter sinks, and described screw 3 passes counter sink and enters in tapped hole on boss 4 retainer 2 is fixing with fastener 1; The cross section of boss described in the present embodiment 4 is quadrangle.Certainly, the cross section of described boss 4 also can be triangle polygonal even; Or the cross section of described boss 4 also can be ellipse non-circular shape even regularly.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The anti-rotation locking structure of the described single screw of the present invention program, when described boss 4 inserts in counter sink, when described screw 3 passes counter sink and enters in tapped hole on boss 4 retainer and fastener fixedly, because described boss 4 is non-cylindrical, described counter sink is similar to the shape of boss 4, retainer 2 can not rotate around screw 3 like this, thereby can prevent relatively rotating of retainer 2 and fastener 1.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
