Abstract
A skid-proof bolt comprises a bolt and a bolt head. A rectangular pyramid spine structure is arranged on the upper side surface of the bolt head and integrated with the bolt head by casting method. A bump is arranged on the bolt head. When the bolt is connected with a nut, the bump acts on the surface of the parts and a certain pressure is applied and increased along with the screwing-down of the nut, thus the bolt does not easily rotate together with the nut when the nut is nearly screwed down by one hand and the operation is convenient and the working efficiency is increased. The bump uses a tip-shaped structure with a tip and casted with the bolt head and when under pressure, the parts to be connected can be properly pressed into to increase the action force of the bolt and the parts to be connected, thus the bolt does not easily rotate.
Description
Technical field
The utility model relates to mechanical field, and particularly mechanical fastener specifically is a kind of bolt that can be anti-skidding.
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 rectangular pyramid spine structure at this bolt head upper side, this rectangular pyramid spine structure and bolt head are an integral body.
This rectangular pyramid spine structure constitutes overall structure by casting method and bolt head.
Evenly be distributed with at least two these rectangular pyramid spine structures along the bolt shank axis.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model can be anti-skidding bolt projection is set 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.

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 utility model can be anti-skidding bolt, comprise screw rod 1 and bolt head 2, be provided with rectangular pyramid spine structure 3 at these bolt head 2 upper sides, this rectangular pyramid spine structure 3 is an integral body with bolt head 2, this rectangular pyramid spine structure 3 constitutes overall structure by casting method and bolt head 2, evenly is distributed with two these rectangular pyramid spine structures 3 along the bolt shank axis.
Claims (3)
- One kind can be anti-skidding bolt, comprise screw rod and bolt head, it is characterized in that: be provided with rectangular pyramid spine structure at this bolt head upper side, this rectangular pyramid spine structure and bolt head are an integral body.
- 2. bolt that can be anti-skidding as claimed in claim 1 is characterized in that: this rectangular pyramid spine structure constitutes overall structure by casting method and bolt head.
