Abstract
The invention discloses a kind of anti-fracture special-shaped fastener, by the spacing of the drawing of bow and the first spring washer and the second spring washer, it can prevent U-shaped body bend pipe aperture under expansion external force effect from becoming greatly so as to deform or even fracture；And the elasticity of the first spring washer and the second spring washer, the faint deformation of U-shaped body is met again carries out self-adjusting demand.Similarly, the setting of the 3rd spring washer, you can prevent U-shaped body bend pipe aperture under extruding force effect from diminishing so as to deform or even fracture, meet the faint deformation of U-shaped body again and carry out self-adjusting demand.In the present invention, the setting of bow, the direction of U-shaped body deformation also limit so that the deformation of U-shaped body ensures U-shaped body running performance close to the rule of internal relaxation power.
Description
Technical field
The present invention relates to automobile fitting manufacturing technology field, more particularly to a kind of anti-fracture special-shaped fastener.
Background technology
U-shaped fastener is the common part for being used to connect in auto parts machinery.There is one of bending in U-shaped fastener production process
Process so that the inside relaxation power of the bending section of finished product U-shaped fastener damages, so as to impair the service life of U-shaped fastener
And security performance.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of anti-fracture special-shaped fastener.
The anti-fracture special-shaped fastener of one kind proposed by the present invention, including：U-shaped body and bow；
U-shaped body is made up of integrally formed knee and two straight-bars, and two straight-bars connect the both ends of knee, and two respectively
The one end of straight-bar away from knee is equipped with external screw thread；Perforation is respectively equipped with two straight-bars, the both ends of bow are each passed through two
Perforation on root straight-bar；
The first end of bow and the second end are respectively equipped with first baffle and second baffle, and bow first end passes through straight-bar
Part be arranged with the first spring washer, the end of bow second is arranged with the second spring washer through the part of straight-bar, and bow is located at two
Part between straight-bar is arranged with the 3rd spring washer.
Preferably, bow is located at using knee midpoint as on the circle in the center of circle.
Preferably, first baffle is integrally formed with bow.
Preferably, the first spring washer, the second spring washer and the 3rd spring washer material are identical.
Preferably, the first spring washer, the second spring washer and the 3rd spring washer are made of rubber.
The anti-fracture special-shaped fastener of one kind proposed by the present invention, passes through the drawing of bow and the first spring washer and the second bullet
That pads is spacing, can prevent U-shaped body bend pipe aperture under expansion external force effect from becoming greatly so as to deform or even fracture；And the first spring washer and
The elasticity of second spring washer, the faint deformation of U-shaped body is met again and carries out self-adjusting demand.Similarly, the setting of the 3rd spring washer, you can
Prevent U-shaped body bend pipe aperture under extruding force effect from diminishing so as to deform or even fracture, meet the faint deformation of U-shaped body again and carry out
Self-adjusting demand.
In the present invention, the setting of bow, the direction of U-shaped body deformation also limit so that the close inside of the deformation of U-shaped body
The rule of relaxation power, ensure U-shaped body running performance.
Brief description of the drawings
Fig. 1 is the anti-fracture special-shaped fastener constructions figure of one kind proposed by the present invention；
Fig. 2 is the anti-fracture special-shaped fastener sectional view of one kind proposed by the present invention.
Embodiment
Reference picture 1, Fig. 2, the anti-fracture special-shaped fastener of one kind proposed by the present invention, including：U-shaped body 1 and bow 2.
U-shaped body 1 is made up of integrally formed knee and two straight-bars, and two straight-bars connect the both ends of knee, and two respectively
The one end of root straight-bar away from knee is equipped with external screw thread.In present embodiment, the difference of U-shaped body 1 and common U-shaped bar is,
Perforation is respectively equipped with two straight-bars of the U-shaped body 1.
The both ends of bow 2 are each passed through the perforation on two straight-bars.The first end of bow 2 and the second end are respectively equipped with
First baffle 3 and second baffle 4, the first end of bow 2 are arranged with the first spring washer 5, the end of bow 2 second through the part of straight-bar
The second spring washer 6 is arranged with through the part of straight-bar, part of the bow 2 between two straight-bars is arranged with the 3rd spring washer 7.
In this way, by the spacing of the drawing of bow 2 and the first spring washer 5 and the second spring washer 6, it can prevent U-shaped body 1 from expanding
The lower bend pipe aperture of external force effect is opened to become greatly so as to deform or even fracture；And the elasticity of the first spring washer 5 and the second spring washer 6, meet again
The faint deformation of U-shaped body 1 carries out self-adjusting demand.Similarly, the setting of the 3rd spring washer 7, you can prevent U-shaped body 1 in extruding force
The lower bend pipe aperture of effect diminishes so as to deform or even fracture, and meets the faint deformation of U-shaped body 1 again and carries out self-adjusting demand.
In present embodiment, the setting of bow 2, the direction that U-shaped body 1 deforms also limit so that the deformation of U-shaped body 1
Close to the rule of internal relaxation power, ensure the U-shaped service behaviour of body 1.
Specifically, in present embodiment, bow 2 is located at using knee midpoint as on the circle in the center of circle, i.e. perforation is located at curved
Bar midpoint is on the circle in the center of circle.
In present embodiment, first baffle 3 is integrally formed with bow 2.
In present embodiment, the first spring washer 5, the second spring washer 6 are identical with the material of the 3rd spring washer 7, to ensure that U-shaped body 1 deforms
When the pressure balance that is subject to from the first spring washer 5, the second spring washer 6 and the 3rd spring washer 7, so as to ensure that the form of U-shaped body 1 recovers energy
Power.Specifically, the first spring washer 5, the second spring washer 6 and the 3rd spring washer 7 are made of rubber.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
