Abstract

The utility model provides a novel fastening bolt. The novel fastening bolt comprises a nut and a screw rod which are fixedly connected. One end of the screw rod away from the nut is provided with threads, one end of the screw rod close to the nut is provided with an anti-looseness gasket, the surface of the anti-looseness gasket close to the nut is a conical face, an outer wall of a screw rod cylindrical body is provided with a radial groove, and an axial through hole is arranged at the axis position of the screw rod. The anti-looseness gasket is arranged on the screw rod of the novel fastening bolt, and one end of the gasket close to the nut is the conical face, so that when the bolt is screwed up, the conical face deforms and plays the effect of the elastic gasket, and accordingly the bolt looseness is prevented. The groove on the outer wall of the bolt cylindrical body enables produced impurities on the rusted threads or a rusted fixed nut to be discharged out, the bolt can be screwed easily, and the service life of the bolt is prolonged. In addition, by means of the axial through hole of the screw rod, materials are greatly saved, and the formed bolt is light in weight.

Description

A kind of Novel fastening bolt
Technical field
The utility model relates to technical field of fastening, relates in particular to a kind of locking, economical with materials, can overcome the Novel fastening bolt that screw thread gets rusty, effectively gets rid of screw thread rust stain and impurity.
Background technique
Traditional bolt comprises screw rod and nut, and described nut is fixedly connected with screw rod.When the bolt of prior art uses in the equipment of vibrations, easily become flexible, come off, thereby affect the functional reliability of equipment; During use, easily get rusty, have impurity on the screw thread of bolt or set screw nut, can't get rid of and cause folding dress difficulty; In addition, existing bolt is generally solid bolt, and consumptive material is many, also heavier after the moulding.
The model utility content
Be difficult for when problem to be solved in the utility model provides a kind of the use loosening, can effectively get rid of rust stain and impurity on the screw thread and save material, bolt that weight is lighter.
The technical solution of the utility model is as follows: a kind of Novel fastening bolt, comprise nut and screw rod, described nut is fixedly connected with screw rod, end away from nut on the described screw rod is provided with screw thread, it is characterized in that: the end near nut on the described screw rod is provided with check washer, the external wall of described screw column is provided with a radial groove, and place, described screw rod axle center is provided with axial hole.
Further, described check washer is conical surface near the surface of nut.
The beneficial effects of the utility model are: this Novel fastening bolt screw rod is provided with check washer, and pad is conical surface near an end of nut, and when bolt tightening, this conical surface produces deformation, plays the effect of resilient pad, thereby prevents bolt looseness; Groove design on the external wall of bolt column can make the impurity that produces that gets rusty on screw thread or the set screw nut discharge by groove, makes the bolt rotation light, has prolonged the working life of bolt; In addition, material has been saved in the design of screw rod axis through-hole greatly, also makes the bolt weight after the moulding lighter.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, nut, 2, screw rod,
3, screw thread, 4, check washer,
5, conical surface, 6, groove,
7, through hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made brief description.
As shown in the figure: a kind of Novel fastening bolt, comprise nut 1 and screw rod 2, described nut 1 is fixedly connected with screw rod 2, end away from nut 1 on the described screw rod 2 is provided with screw thread 3, it is characterized in that: the end near nut 1 on the described screw rod 2 is provided with check washer 4, described check washer 4 is conical surface 5 near the surface of nut 1, and described screw rod 2 cylinder outer walls are provided with a radial groove 6, and place, described screw rod 2 axle center is provided with axial hole 7.
Working method: this Novel fastening bolt in use, the screw rod 2 of bolt is passed the through hole of fastening piece, cooperate with corresponding nut and to tighten, this moment is under the effect of external force, conical surface 5 can produce deformation, play the effect of resilient pad, thereby prevent bolt looseness, bolt closely is connected with fastening piece; Usually the rust stain that produces on screw thread 3 or the set screw nut can be discharged by the groove 6 of bolt outer wall by turning bolt.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
