Description
Technical field
The utility model relates to fastener areas, is specifically related to a kind of bolt.
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 shaken, easily loosen, come off, thus affect the functional reliability of equipment.
Application number is the Chinese patent " a kind of Novel fastening bolt " of 201220500668.9, disclose a kind of Novel fastening bolt, comprise nut and screw rod, described nut is fixedly connected with screw rod, one end away from nut on described screw rod is provided with screw thread, it is characterized in that: the one end near nut on described screw rod is provided with check washer, and the external wall of described screw column is provided with a radial groove, and described screw rod axle center place is provided with axial hole.Described check washer is conical surface near the surface of nut.By being provided with the deformation of check washer by after bolt tightening, this conical surface produces deformation, plays the effect of resilient pad, thus prevents bolt looseness, but after this kind of check washer repeatedly use, deformation quantity weakens, locking inefficacy.
Thus in order to solve the problem that check washer lost efficacy, application number is the Chinese patent " anti-loosening bolt fastener " of 201320089524.3, disclose a kind of anti-loosening bolt fastener, comprise spiral shell head (1) and screw rod (2), it is characterized in that: described spiral shell head (1) is provided with tip (3).This programme will substituted for above-mentioned check washer by tip, also solve loosening problem simultaneously, also the object that service life is long simultaneously, but the equipment connected by fastening piece or product are all generally have hard straight material to make, thus be difficult to good contact between surface and the tip of bolt, thus anti-loosing effect is in fact very bad.
Model utility content
For the deficiency that prior art exists, it is good that the purpose of this utility model is to provide a kind of anti-loosing effect, the bolt that access times are many.
For achieving the above object, the utility model provides following technological scheme: a kind of bolt, the screw rod comprising bolt head and be wholely set with bolt head, the second threaded stem that described screw rod comprises the first threaded stem, be wholely set with bolt head and the round bar that two ends are wholely set with the first threaded stem and the second threaded stem respectively, described first threaded stem is identical with the hand of spiral of the second threaded stem, described first screw thread is provided with the fastening nut for clamping bolt.
By adopting technique scheme, screw rod on bolt comprises three parts, comprise the second threaded stem successively, round bar and the first threaded stem, when using this bolt, corresponding threaded holes on first threaded stem and equipment closes, on the second threaded stem, be arranged with fastening nut simultaneously, first threaded stem is identical with the hand of spiral of the second threaded stem, fastening nut is installed to the second threaded stem can by being introduced on the first threaded stem, the step that minimizing screw thread process is set of round bar, make fastening nut enter on the first threaded stem sooner simultaneously, suppose that bolt is tightened clockwise, after the parts such as the first threaded stem and equipment being tightened by rotating bolt head, again by tightening fastening nut clockwise, because fastening nut and parts are fitted, because position can keep inconvenience, make bolt to be ejected toward member outside when rotating, the screw thread of the first threaded stem and the screw thread of parts is stuck realizes fastening locking object, good stability and endurance is all had compared to check washer of the prior art or tip.
Of the present utility modelly to be set to further: between described fastening nut and bolt head, be provided with rubber washer.
By adopting technique scheme, rubber washer be arranged so that when fastening nut is arranged on the first threaded stem, fastening nut can be compressed rubber washer tentatively to tighten, prevent fastening nut from loosening, at the whole bolt of tension be simultaneously, rubber washer can provide certain surplus and frictional force, makes fastening nut effectively can add fixing bolt.
Of the present utility modelly to be set to further: described fastening nut arranges relative to the other end of rubber washer and arranges bar-shaped trough more.
By adopting technique scheme, being provided with in one end of fastening nut and arranging bar-shaped trough more, reduce the area of contact of fastening nut and parts, change linking work at selected spots with that in entire areas of background technique sharp head the combination of into face, face, fastening nut and parts also can well be fitted.
Of the present utility modelly to be set to further: described round bar is provided with through hole.
By adopting technique scheme, the through hole that round bar is provided with is the distortion causing bolt entirety in order to the deformation of generation when preventing the fastened nut of bolt from stretching, and causes using.
Of the present utility modelly to be set to further: the cross section of described bolt head and fastening nut is regular hexagon.
By adopting technique scheme, it is more convenient that being arranged so that of six prisms rotates this bolt.
The utility model has following advantage: be provided with fastening nut at screw rod near bolt head side, is tightened, effectively prevent bolt looseness by fastening nut direction, improves practicability and stability.
Accompanying drawing explanation
