Description
[technical field]
The utility model relates to the technical field of bolt, the technical field of the bolt particularly with pad.
[background technique]
The bolt of prior art comprises nut and screw rod, described nut is fixedly connected with screw rod, and this bolt exists a lot of deficiencies in actual use, when this bolt uses on the equipment shaken, such as automobile bearing, high-speed railway rails etc., are easy to occur to loosen situation about dropping, affect the reliability of the work of equipment, and the bolt hole structure of existing bolt is single, serious wear after how many uses, working life is not long, is therefore necessary to propose a kind of bolt with pad.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of bolt with pad, and the fastening effect of bolt can be made better, and not easily loosen and skid, more difficult wearing and tearing, longer service life, structure is simple.
For achieving the above object, the utility model proposes a kind of bolt with pad, comprise bolt head, screw rod, pad, thread section, hole clipping, bolt mouth, circular protrusions, be provided with screw rod below described bolt head, be provided with pad below described bolt head, described screw rod is provided with thread section, described screw rod lower end is provided with hole clipping, described bolt head is provided with bolt mouth, and described bolt mouth central authorities are provided with a circular protrusions, and the lower surface of described pad is provided with some anti-skidding grooves.
As preferably, described hole clipping is located at the rear portion of thread section, and described hole clipping is manhole, for fixing bolt, prevents bolt looseness.
As preferably, the upper surface of described pad is conical surface, the lower surface of described pad is provided with some anti-skidding grooves, the quantity of described anti-skidding groove is 15 ~ 20, between every two anti-skidding grooves, interval is identical, conical surface produces the effect that deformation can play compression spring, and anti-skidding groove has one-way, can play the effect of good anti-reversing.
As preferably, described bolt mouth is quincunx bolt mouth, and described bolt mouth is provided with six cambered surfaces, described cambered surface is uniformly distributed centered by circular protrusions, the area of contact of instrument and bolt mouth when can increase swivel bolt, prevents instrument to skid wearing and tearing bolt mouth, easier clamping bolt.
As preferably, the height of described circular protrusions is less than the degree of depth of bolt mouth.
The beneficial effects of the utility model: the utility model by installing a pad additional below bolt head, the upper surface of pad is conical surface, can fastening again time there is deformation, play the effect of compression spring, the lower surface of pad is provided with anti-skidding groove, anti-skidding groove has one-way, can prevent bolt from skidding and reverse, a circular hole clipping is established in the below of screw rod, can be fixed with fixed component after bolt installs, prevent from bolt from shaking to come off, improve fastening effect and working life, and adopt quincuncial bolt mouth, not easily skid when making instrument turn bolt, reduce wear.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
