Abstract
The utility model discloses a press-installation type trip bolt or threaded bolt with blind holes; besides, the utility model is used for fastening and connecting metal plates. The tail of the utility model is provided with a centripetal oblique slot and two steps connected by the oblique slot, the thickness and the diameter of a step on one end are smaller than the thickness and the diameter of the second step, and the circumference of the excircle of the second step is provided with axial teeth. The utility model has high connecting strength and is anti-vibration and anti-shock, and the appearance quality of the connected metal plates is improved.
Description
The utility model relates to a kind of fastening coupling device, particularly a kind of pressing type fastening screw trip bolt or bolt.
At present, with the cabinet panel of the fastening connection metal of riveting screw, furniture etc., all be that the screw riveting is gone in the through hole of panel, for attractive in appearance, must equating ailhead Puttying and careful paint hide the nail hole again, its shortcoming is a complex process, take material, rivet is vibrated or is impacted easily and become flexible, and liquid, gas etc. easily infiltrate in the panel from the nail hole, and the time is just damaged finish paint or the variable color of turning to be yellow than long, also influence linking intensity, the way that has human to paste one deck filler panel hides the nail hole, has both increased cost, can not tackle the problem at its root again.
The purpose of this utility model is, improves at the deficiency that prior art must the through hole riveted joint, provides a kind of linking intensity that can guarantee not reveal blind hole pressing type fastening screw trip bolt or the bolt of following closely the hole again.
Technical solution of the present utility model is, designs a kind of special construction at the afterbody of screw or bolt, makes in its blind hole that is press fit into the sheet metal back side, can rely on the plastic deformation of blind hole interior metal, plays fastening anastomosis.Specifically, the afterbody of the utility model screw or bolt has two steps of skewed slot entad and connection thereof, and the thickness of tail end step and diameter are less than the thickness and the diameter of second step, and the second step outer annulus edge has axial tooth.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model overall structure schematic representation.
As shown in the figure, two steps 3,1 that pressing type fastening screw trip bolt or bolt tail have skewed slot 2 entad and connect, the thickness of tail end step 3 and diameter are less than the thickness and the diameter of second step 1, and second step 1 outer annulus edge has axial tooth 6.Blind hole 4 diameters at metal surface 5 back sides are identical with screw or bolt tail step 3 diameters, when screw or bolt tail are pressed into blind hole 4, step 1 lower end surface angle is clamp-oned the panel material cutting-out (root does not cut off) at blind hole edge in the skewed slot 2, and step 1 is pressed in the blind hole together with the axial tooth 6 of its outer annulus edge.The axial tooth 6 that the utility model utilization is pressed in the blind hole 4 reaches antitorque purpose, utilizes the panel material riveting of clamp-oning in the groove 2 to live the purpose that step 3 reaches tension, and the crush resistance of axial tooth and hole wall also plays the effect of part tension.Experimental result shows that the aluminium panel of the utility model and 4mm and above thickness thereof press-fits the back linking intensity and can reach:
Screw, bolt axial tension (newton) moment of torsion (Newton meter)
The minimum minimum breakdown torque of pulling force allowable torque that destroys of specification pulling force allowable
M
3300 500 0.6 0.8
M
4600 1000 1.2 2
M
51200 2000 2 4
The strength criterion that grade bolt such as meets, shock-resistant, vibration can be applied to the connection of sheet metal such as aluminium, steel or other metal parts, changed traditional through hole connecting mode, simplified flow, reduced cost, improved connect the appearance quality of sheet metal.
Claims (1)
1, a kind of pressing type fastening screw trip bolt is characterized in that afterbody has two steps of skewed slot entad and connection thereof, and less than the thickness and the diameter of second step, the second step outer annulus edge has axial tooth respectively for the thickness of tail end first step and diameter.
