The gear-shaping and rivet-turning combination anti-rotate locking unit assembly is convenient to use, not prone to loosing during use, reliable in connection, simple in structure, good in processing, capable of simplifying devices, fast to install, interchangeable and worthy of popularization.
Description
Technical field
The utility model relates to a kind of gear shaping and adds the combination anti-rotation lock nut assembly that turns over riveting, belongs to technical field of fastening.
Background technique
At present, in some special environment, the installation of usually carrying out nut by support is fixed, and support and coordinating of nut are single riveting or the single gear shaping structure of turning over mostly, the means of fixation of this nut is to meet the demands under normal conditions, but when external force was excessive, nut easily was pushed out support, therefore, existing anti-rotation lock nut assembly is in the situation that to bear larger external force be undesirable.
Summary of the invention
The purpose of this utility model is the combination anti-rotation lock nut assembly that turns over riveting for overcoming the deficiencies in the prior art, providing a kind of gear shaping to add, and makes nut in the situation that bear larger external force and can be fixed on support, and can prevent that nut from rotating on support.
For realizing the purpose of this utility model, a kind of gear shaping of the present utility model adds the combination anti-rotation lock nut assembly that turns over riveting, comprise nut and support, wherein, described frame bottom is arranged with two mounting holes, and described nut is riveting dress self-locking round nut, and the threaded end of nut is provided with closing-in structure, non-threaded end is provided with the straight-tooth that can inject described mounting hole, and the aperture of mounting hole is less than the external tooth standard pitch diameter of nut straight-tooth; Described mounting hole bottom is provided with chamfering structure.
Further, above-mentioned gear shaping adds the combination anti-rotation lock nut assembly that turns over riveting, and wherein, the chamfer angle of described chamfering structure is 90 °～120 °, and depth of chamfering is half of backing thickness.
Further, above-mentioned gear shaping adds the combination anti-rotation lock nut assembly that turns over riveting, and wherein, described mounting hole is the unthreaded hole structure.
Further, above-mentioned gear shaping adds the combination anti-rotation lock nut assembly that turns over riveting, and wherein, described support dual-side is provided with the relative hole that pre-fixes.
Nut of the present utility model is riveting dress self-locking round nut, screw thread is regular screw threads, threaded end closes up, realize self-locking, a non-threaded end processing straight-tooth, realization is pressed into the function of support, nut itself is without the twisting structure, frame bottom boring, bottom one chamfer, nut and support add by straight-tooth turns over the riveting knot structure and realizes that nut and support fix.After adopting gear shaping to add to turn over the riveting knot structure, prevent that more easily self-locking nut from rotating, the maximum that gear shaping turns over the riveting back nut is again released more than moment can reach 100N, in use be enough to make being connected firmly of nut and support, realized the high strength installation of nut and support, increase the reliability that is fastenedly connected, still be difficult to be pushed out support at the situation lower nut that bears larger external force; The method is easy to use, when using, difficult generation is loosening, connection is safe and reliable, simple in structure, processability is good, realizes simplified apparatus, quick mounting, and have interchangeability, be worthy to be popularized.

Embodiment.
The utility model is described in further detail below in conjunction with drawings and Examples.
First see Fig. 5, what Fig. 5 showed is the structural representation of nut 1 of the present utility model, and what in figure, the first half was showed is the surface structure of nut 1, and what Lower Half was showed is the sectional structure of nut 1.As seen from the figure, screw thread is regular screw threads to 1, nut as riveting dress self-locking round nut, and threaded end closes up, and realizes self-locking, a non-threaded end processing straight-tooth 3, and realization is pressed into the function of support 2, and nut 1 is own without the twisting structure.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, what show in three figure is that a kind of gear shaping adds the combination anti-rotation lock nut assembly that turns over riveting, its major component comprises nut 1 and support 2, be arranged with two mounting holes 5 in support 2 bottoms, nut 1 is arranged in described mounting hole 5, the aperture of mounting hole 5 is slightly less than the external tooth standard pitch diameter of straight-tooth 3, after the straight-tooth 3 of nut 1 inserts mounting hole 5 like this, can be fixed in mounting hole 5 because interference fit makes nut 1; Described mounting hole 5 bottoms are provided with chamfering structure 6, the chamfer angle of chamfering structure 6 is 90 °～120 °, depth of chamfering is half of support 2 thickness, the purpose of chamfering is after straight-tooth 3 one side pressures of nut 1 enter support 2, turn over straight-tooth 3 bottoms of Insert Nut 1, make straight-tooth 3 bottoms of nut 1 form flared structures and be adjacent to chamfering on support 2 and realize turning over rivet clasp calmly.Fix and turn over rivet clasp and decide under acting in conjunction, nut 1 to be fixed on support 2 at gear shaping, and prevent that nut 1 from rotating on support 2.
See Fig. 4, described mounting hole 5 is the unthreaded hole structure, and there is chamfering structure 6 bottom, and support 2 dual-sides are provided with the relative hole 4 that pre-fixes, the effect that pre-fixes hole 4 is to install at nut assembly that support 2 is front first to be pre-fixed nut assembly in corresponding position, so that carry out the installation of nut 1.
Embodiment of the present utility model: nut 1 of the present utility model itself adopts traditional material to make, and nut 1 riveted joint end adopts external tooth rolling processing method to form straight-tooth 3, and threaded end closes up, and makes nut 1 itself realize auto-lock function.Support 2 is selected stainless steel materials, completes the processing of profile through bending and forming repeatedly, processes at last the mounting hole 5 of the symmetry of two in support 2 bottoms, and the aperture, bottom of mounting hole 5 processes chamfering structure 6, is easy to realize coordinate with the riveting of turning over of nut 1.During assembling, straight-tooth 3 ends of nut 1 push support 2, then by turning over easily riveting tool, straight-tooth 3 are turned over riveting.In addition, be drilled with the relative hole 4 that pre-fixes at the dual-side of support 2.
