Abstract
The utility model discloses a bolt with anti-slip structure comprising a screw and a bolt head, wherein the bolt head is provided with a protruding structure on side surface thereof, the protruding structure integrating with the bolt head into one piece by casting, the protruding structure being a triangular pyramid, the screw being evenly provided with at least two said protruding structures along axial direction. The protruding structure on the bolt head of the utility model and the surface of the part will mutually impose pressure on each other as bolt and nut are connected to each other. As screwing of nut is increased, the pressure becomes larger. As the nut is close to be screwed up, the bolt is not easily to rotate along the nut. The utility model possesses a screw which can be screwed with one hand, combined with convenient operation and high working efficiency.
Description
Technical field
The utility model relates to mechanical field, and particularly mechanical fastener specifically is a kind of bolt with anti-skid structure.
Background technique
Bolt is widely used in the connection between the part as mechanical fastener.Generally, can the bolt head on the screw rod be fixed by spanner when screwing nut, when nut begins to screw, be unlikely to make screw rod and then to rotate like this.And under the operating conditions that has, such as the aerial power equipment of height, wherein also use bolt connection piece, inconvenient operation was not easy to vacate two hands usually and turned round a bolt simultaneously, like this when nut begins to screw this moment, bolt may and then rotate, make nut disposablely not screw, prolonged the operating time, inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of bolt with anti-skid structure, the bolt of described this band anti-skid structure will solve in the prior art when nut begins to screw bolt shank and can and then rotate and cause being not easy to nut screwing clamping, makes long, ineffective technical problem of operating time.
The purpose of this utility model is achieved through the following technical solutions: comprise screw rod and bolt head, wherein, be provided with protruding structure at this bolt head upper side, this protruding structure and bolt head are an integral body.
This protruding structure is to have most advanced and sophisticated structure, and its structure is up-small and down-big.
This protruding structure constitutes overall structure by casting method and bolt head.
Evenly be distributed with at least two these protruding structures along the bolt shank axis.
This protruding structure is a triangular pyramid.
The utility model is compared with prior art, and its effect is actively with tangible.The bolt of the utility model band anti-skid structure is provided with projection on bolt head, when bolts and nuts connect, this projection acts on mutually with therebetween part surface, applies certain pressure, along with screwing of nut, this pressure is big more, like this when nut when tightening, bolt also is not easy to follow nut and rotates, and can bolt be screwed a hand, easy to operate, increase work efficiency.This projection adopts has most advanced and sophisticated sharp structure, and is cast as one with bolt head, when being under pressure, can suitably be pressed into connected part, improves screw rod and the active force that is connected between the part, makes screw rod be not easy to rotate.
Description of drawings
Fig. 1 is the structural representation of the bolt of band anti-skid structure of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the bolt of the utility model band anti-skid structure, comprise screw rod 1 and bolt head 2, wherein, be provided with protruding structure at these bolt head 2 upper sides, this protruding structure is a triangular pyramid 3, and these triangular pyramid 3 structures constitute overall structure by casting method and bolt head 2, evenly are distributed with three these triangular pyramid structures along the bolt shank axis.
Carry out once axially hammering from end face when bolt uses, the effect of triangular taper spine is to embed the fastener surface, makes bolt and the fastener frictional force frictional force greater than bolt and nut, and bolt has rotated with regard to not following nut again during rotary nut.
