Background technique
At present, the brad that market occurs, as shown in Figure 1, comprise rivet nut 1 and nail angle 2, angle arranges a single hangnail with nail; When using this kind of brad to fix, nail angle 2 is squeezed on the object needing attachment, this brad mainly by the single hangnail on nail angle 2 promptly, due to the grip of single thorn and tensile strength limited, easily occur loosening or come off.
The improvement made this arranges attachment hole 3 in rivet nut 1, second consolidation is carried out through attachment hole 3 with plain screw, although effect has larger improvement compared with the former, when accompanying object is existed to vibrations or requires higher, be still difficult to meet the demands completely.
Model utility content
The purpose of this utility model is: for existing brad be difficult to meet vibrations or other require higher when fixing requirement, a kind of brad fixing device is provided.
A kind of brad fixing device of the utility model, comprise rivet nut and nail angle, also comprise screw assembly, described rivet nut has attachment hole, described screw assembly is through described attachment hole with matching;
Described screw assembly comprises fastening screw trip bolt and extrusion screw, described fastening screw trip bolt comprises fastening screw ailhead, fastening screw trip bolt bar, described fastening screw ailhead is arranged on fastening screw trip bolt bar one end, described fastening screw trip bolt bar is provided with outside thread, is provided with the tapped hole of connection in the middle of described fastening screw ailhead, fastening screw trip bolt bar; Described extrusion screw comprises extrusion screw head, extrusion screw bar, and described extrusion screw head is arranged on extrusion screw bar one end, and described extrusion screw bar is provided with outside thread; Described extrusion screw bar is arranged in described tapped hole; The outside thread that described fastening screw trip bolt bar is arranged is consistent with the external thread rotary veer that described extrusion screw bar is arranged.
Further, described tapped hole is provided with tapering, and when extrusion screw bar is screwed into the tapped hole of fastening screw trip bolt, described fastening screw trip bolt bar expands or distortion.
Further, described nail angle is provided with 2 hangnails.
Further, the quantity at described nail angle is 2 or 4.
Further, described attachment hole is one or more.
Further, described attachment hole shape is circular or oval.
The beneficial effects of the utility model are: extrusion screw is screwed into the tapped hole of fastening screw trip bolt, fastening good fastening screw trip bolt is expanded or distortion, destroys the outside thread of fastening screw trip bolt, reach the object preventing from loosening; Follow closely the two hangnail in angle simultaneously and replace single hangnail, add the grip at nail angle; Simply, durable, be connected firmly.
