Abstract

A bolt with an antiskid structure comprises a bolt rod and a bolt head. Conical spiked structures arranged on the lateral surfaces of the bolt head are integrated with the bolt head by means of casting, and at least two conical spiked structures are evenly distributed along the axis of the bolt rod. When the bolt is connected with a nut, a projection arranged on the bolt head of the bolt with the antiskid structure interacts with the surface of a part between the bolt and the nut and exerts certain pressure, and the pressure is increased as the nut is screwed. Accordingly, when the nut is nearly screwed up, the bolt is not easy to rotate along with the nut and can be screwed up with one hand, and the bolt is convenient in operation and improves working efficiency. The projection in a pointed structure with a pointed end is integrally cast with the bolt head, and can be properly pressed into a part to be connected when being pressed so as to improve acting force between the bolt rod and the part to be connected and lead the bolt not to rotate easily.

Description

Bolt with anti-skid structure
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, be provided with conical spine structure at this bolt head upper side, this taper shape spine structure and bolt head are an integral body.
This taper shape spine structure constitutes overall structure by casting method and bolt head.
Evenly being distributed with at least two along the bolt shank axis should taper shape spine structure.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with projection at the bolt of band anti-skid structure 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 with bolt of anti-skid structure of the present utility model.
Fig. 2 is the schematic three dimensional views with bolt of anti-skid structure of the present utility model.
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 utlity model has the bolt of anti-skid structure, comprise screw rod 1 and bolt head 2, be provided with conical spine structure 3 at these bolt head 2 upper sides, this taper shape spine structure 3 is an integral body with bolt head 2, this taper shape spine structure 3 constitutes overall structure by casting method and bolt head 2, and evenly being distributed with two along the bolt shank axis should taper shape spine structure 3.
Can carry out once axially hammering from end face when bolt uses, the effect of conical 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.
Certainly, the bolt head upper side also can be provided with three or more conical spine structures, and the increase of spine number of structures can increase the active force between bolt and the connected piece, and is more favourable to preventing that bolt shank from rotating.

Claims (3)

1. the bolt with anti-skid structure comprises screw rod and bolt head, it is characterized in that: be provided with conical spine structure at this bolt head upper side, this taper shape spine structure and bolt head are an integral body.
2. the bolt with anti-skid structure as claimed in claim 1 is characterized in that: this taper shape spine structure constitutes overall structure by casting method and bolt head.
3. the bolt with anti-skid structure as claimed in claim 1 is characterized in that: evenly being distributed with at least two along the bolt shank axis should taper shape spine structure.
