Abstract
The utility model relates to a kind of riveted joint bolt, especially a kind of flat side's riveted joint bolt.Comprise joint, screw section, flat quadrate part, screw section and flat quadrate part are separately positioned on the two ends of joint, and one-body molded with joint, and flat quadrate part is divided into circular arc part and flat, and the top outer rim of described flat quadrate part is the inclined-plane of arc-shaped.The top outer rim of flat quadrate part is the inclined-plane of arc-shaped by said structure, the situation of card so would not be there is when installing, convenient when installing, by the leading role on inclined-plane, flat side more easily enters mounting hole, avoid the easy clamping stagnation in traditional right angle, flat side top and the easy problem producing unhealed cracks, thus extend working life.
Description
Technical field
The utility model relates to a kind of riveted joint bolt, especially a kind of flat side's riveted joint bolt.
Background technique
The connection of riveting nut and riveted joint bolt a kind ofly need to be punched in advance, from the Placement that both sides processing connects with functional element (screw thread).Add man-hour first nut be placed in pre-manufactured hole, then use special tool to make fringe region and the riveting nut in hole, riveted joint bolt produces distortion and forms the connection that a power and shape close.Therefore riveted joint bolt can not loosen after fixation substantially, has very high requirement to the fastness of riveted joint.
At present, the connection for every profession and trade component that the riveted joint bolt of the flat side of the threaded one end the other end is a large amount of and fastening, when some presses assembling, only to need to press with counterpart or revolve together with riveting his fairly simple location and can light mounting nuts, thus commonplace and applicable when use assembling nut.
And this extraordinary riveted joint bolt assembling extensively adopts Milling Process manufacture technics with flat square structure, work efficiency is lower, waste raw material, and utilize milling shaping due to flat side, there is a lot of burr in the flat face of so flat side, and flat side top is right angle, due to metallic material generation deformation when riveted joint, be easy to occur riveted joint crackle.
Model utility content
The purpose of this utility model is, provides a kind of long service life, flat side's riveted joint bolt level and smooth, easy for installation.
The utility model solves the technological scheme that its technical problem adopts: a kind of flat side's riveted joint bolt, comprise joint, screw section, flat quadrate part, screw section and flat quadrate part are separately positioned on the two ends of joint, and it is one-body molded with joint, flat quadrate part is divided into circular arc part and flat, and the top outer rim of described flat quadrate part is the inclined-plane of arc-shaped.
The R angle of this top outer rim that flat quadrate part is set to be the inclined-plane of arc-shaped and the end face outer rim of flat quadrate part be arc-shaped, the situation of card so would not be there is when installing, convenient when installing, by the leading role at circular arc R angle, flat side more easily enters mounting hole, avoid the easy clamping stagnation in traditional right angle, flat square end face and easily crack after staking, thus extending working life.
Of the present utility modelly to be set to further: flat is cambered surface with the joint of circular arc part.
This arranges and flat and the joint of circular arc part is set to cambered surface, so when circumference is rotated, the part of strength is cambered surface, area of contact is larger, and therefore pressure bearing is very even, and pressure and torsion distribution all diminish, improve working life of the present utility model, and traditional flat side due to joint be straight flange, therefore in installation or when rotating, the power that straight flange bears is excessive cause product to occur crackle even ruptures.
Of the present utility modelly to be set to further: flat side is by cold-heading molding, and flat is one without the smooth surfaces of groove milling.
This is arranged is arranged to level and smooth plane by flat face, because traditional milling mode cannot make smooth surfaces, only has and just can make level and smooth plane by cold-heading, and level and smooth plane, when installation, is smooth and easy non-resistance, facilitates field riveting bolt; And after riveted joint the deformation of material evenly, can not crack, thus improve working life.
Accompanying drawing explanation
Fig. 1 is the use structural representation of the present embodiment;
Fig. 2 is the partial structurtes schematic diagram of the present embodiment.
Embodiment
Known with reference to figure 1, Fig. 2, a kind of flat side's riveted joint bolt of the utility model, comprise joint 2, screw section 1, flat quadrate part 3, screw section 1 and flat quadrate part 3 are separately positioned on the two ends of joint 2, and one-body molded with joint 2, and flat quadrate part 3 is divided into circular arc part 31 and flat face 32, the top outer rim of described flat quadrate part 3 is the inclined-plane 33 of arc-shaped, flat face 32 is cambered surface with the joint of circular arc part 31, and flat side is by cold-heading molding, and flat face 32 is one without the smooth surfaces of groove milling.
Obviously, above-described embodiment is only used to done citing is clearly described, and the restriction not to mode of execution.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still in protection domain of the present utility model.
