Specific embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
A kind of spring nut, including：Bolt 1, nut 5, spring 4, sleeve pipe 3 and pad 2, bolt 1 are socketed with pad successively
2nd, sleeve pipe 3 and nut 5, spring 4 are socketed on bolt 1, and the one end of spring 4 is fixedly connected with nut 5, and spring 4 is set in sleeve pipe 3
It is interior.
Refer to Fig. 1 to Fig. 3：
Compared with prior art, advantage of the present utility model is：
A kind of nut 5 of spring 4, including：Bolt 1, nut 5, spring 4, sleeve pipe 3 and pad 2, bolt 1 are socketed with pad successively
Piece 2, sleeve pipe 3 and nut 5, nut 5 are connected with spring 4, and spring 4 is stainless steel making, and spring 4 and nut 5 can be by spot welding etc.
Technique is welded, and spring 4 is also socketed on bolt 1, and spring 4 is set in sleeve pipe 3, and the setting direction of spring 4 is to spiral shell
The hexagonal end of bolt 1 extends.
Pad 2 is flat shim 2, grabs any one in shape check washer 2, the check washer 2 of spring 4, can be according to actual need
Select suitable pad 2.
It is significant to note that：Sleeve pipe 3 is T-shaped, and the center of sleeve pipe 3 offers hole, and so that bolt 1 is passed through, 3 points of sleeve pipe is
Pipe portion 32 and pad portion 31, the external diameter of pipe portion 32 are slightly less than connection bore dia, and the internal diameter of pipe portion 32 is more than the external diameter of spring 4, the pad portion of sleeve pipe 3
31 with diameter greater than the hole of connector diameter, additionally, being provided with groove portion, groove portion width and the width phase of nut 5 in the one end of sleeve pipe 3
Together so that nut 5 can snap in sleeve pipe 3, the pipe portion 32 of sleeve pipe 3 also can be set projection.
To improve the performance of sleeve pipe 3, sleeve pipe 3 can use Teflon plastic manufacturing, or special in the Surface coating of common plasticses sleeve pipe 3
Fluorine dragon, it is ensured that the low friction characteristic of material.
Nut 5 is rectangle, and the center of nut 5 offers screwed hole, and the both sides of nut 5 are provided with fixing groove 51, the phase of fixing groove 51
Mutually it be arranged in parallel and fixing groove 51 is provided with anti-slip veins.
The screwed hole both sides of nut 5 it is settable it is anti-release 52, anti-to release 52 for round table-like, anti-releasing 52 points is left and right two
Half, anti-52 middle settings that release have the hole of bolt 1, and the bore dia of bolt 1 is less than the diameter of bolt 1, and anti-52 outsides of releasing are provided with screw thread
Or draw-in groove, anti-releasing 52 can be loosened by nut 5 or jump ring 53.
For convenience of the dismounting of bolt 1, the end sides of bolt 1 are provided with hole, and hole is square hole circular hole or elliptical aperture, can be effective
Insertion crowbar or pin, realize anti-skidding, it is to avoid after mounting because connection tension is difficult to remove.
When actually used, C-shaped section bar is alignd with the hole of bolt 1 of connected material, then, by the patchhole of sleeve pipe 3, needed
It is important to note that sleeve pipe 3 is inserted from connected material side and the pad portion 31 of sleeve pipe 3 is arranged on connected material end,
Upper gasket 2 is first covered on bolt 1, then by the plug-in-sleeve 3 of bolt 1, pad 2 sets from for corner improved mat 2, and pad 2
Put in pad portion 31.
Nut 5 is arranged on C-shaped section bar side, and spring 4 is carefully inserted in bolt 1 so that spring 4 is located at the He of bolt 1
Between sleeve pipe 3, the anti-slip tank of nut 5 is then directed at the both sides protuberance of C-shaped section bar, and effectively fixed, bolt 1 of screwing on, it is real
The connection of existing bolt 1 and nut 5, now, bolt 1 and nut 5 are connected to the side of nut 5, because spring 4 is acted on, effectively keep away
Exempted from thread pitch, improve frictional force realize it is locking, in the side of bolt 1, due to padding the plastics between pad 2 and connected piece
There is certain elasticity in sleeve pipe 3, after the compression of pad 2, it is possible to provide elastic force, the fixation to nut 5 is realized from the side of bolt 1.
Such as can be jump ring 53 in the anti-outer nut 5 that screw on 52 that releases if desired for the anti-loosing effect for further improving nut 5
It is fixed it is anti-release 52, jump ring 53 can be snapped at groove so that the screw thread of the effective hold-down bolt 1 of jump ring 53, it is to avoid vibrations cause
Rotation.
It is of the invention to be a little compared to prior art：
Spring 4 is set by nut 5 and is protected by sleeve pipe 3, realized that elasticity is locking and avoids spring 4 from being connected mouth and cut off
Or corrosion；
By be provided with it is anti-release 52 nut 5, effective locking screw thread improves anti-loose ability.
By the way that in the end providing holes of bolt 1, convenient wrench etc. is fixed, facilitates the dismounting of fastener.
