Abstract
The utility model relates to a double-knurl type bolt, comprising a rod part and a head part, wherein an external thread is arranged on the rod part, the rod part between the external thread and the head part is upwards extended to be provided with an annular flange, a knurl is arranged on the side wall of the annular flange, the rod part between the annular flange and the external thread is upwards extended to be provided with a secondary annular flange, a secondary knurl is arranged on the secondary annular flange, and the outer diameter of the secondary annular flange is smaller than that of the annular flange. By adopting the technical scheme, the double-knurl type bolt not only can prevent the knurls from being scratched and prevent a bolt hole from being swelled heavily, but also can guarantee the connecting reliability of a connecting piece.
Description
Technical field
The utility model relates to bolt field, particularly a kind of pair of annular knurl formula bolt.
Background technique
At present, existing a kind of bolt with annular knurl includes bar portion, head, in bar portion, is provided with outside thread, is outward extended with annular flange flange in the bar portion between outside thread and the head, and the sidewall of annular flange flange is provided with annular knurl.
But, the bolt of the band annular knurl of this structure, the annular knurl on its annular flange flange is scratched when mounted easily, and long-time the use can produce loosening phenomenon, and then influences the reliability that connects between the link; And when mounted, this bolt bolt hole that can swell suddenly, and then make when changing that the assembling of new bolt and bolt hole is often not ideal enough must take other measure to guarantee the reliability that connects between the link.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of pair of annular knurl formula bolt, can guarantee that annular knurl can not be scratched, bolt hole can not swollen suddenly, can guarantee the reliability that link connects again.
The technological scheme of the utility model: a kind of pair of annular knurl formula bolt; Include bar portion, head, described bar portion is provided with outside thread, is outward extended with annular flange flange in the bar portion between outside thread and the head; The sidewall of described annular flange flange is provided with annular knurl; Outwards also be extended with secondary annular flange flange in the bar portion between described annular flange flange and the outside thread, described secondary annular flange flange is provided with secondary annular knurl, and the external diameter of described secondary annular flange flange is less than the external diameter of annular flange flange.
Adopt technique scheme, the secondary annular knurl of setting up can prevent well that the annular knurl on the annular flange flange is scratched, and makes that the connection of link is more reliable; Because the external diameter of secondary annular flange flange is less than the external diameter of annular flange flange, when bolt was installed, bolt hole can not swollen suddenly like this; Thereby can not destroy bolt hole; When changing bolt, need not take other measure to guarantee that the connection of link is reliable yet, make that like this replacing is convenient.
The further setting of the utility model: be connected through chamfering between described secondary annular flange flange and the annular flange flange.
Adopt above-mentioned further setting, chamfering is set, guarantee that further bolt hole can not increased suddenly, makes that the connection of link is more reliable.
Further being provided with again of the utility model: the end face that described secondary annular flange flange is positioned at outside thread one side is provided with the buffering chamfering.
Adopt above-mentionedly further to be provided with again, the buffering chamfering of setting can so that bolt when mounted, secondary annular knurl is not easy to be damaged.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1; A kind of pair of annular knurl formula bolt, the utility model specific embodiment is used for the installation of hub bearing, includes bar portion 1, head 2; Described bar portion 1 is provided with outside thread 11; Be outward extended with annular flange flange 3 in the bar portion 1 between outside thread 11 and the head 2, the sidewall of described annular flange flange 3 is provided with annular knurl 4, outwards also is extended with secondary annular flange flange 5 in the bar portion 1 between described annular flange flange 3 and the outside thread 11; Described secondary annular flange flange 5 is provided with secondary annular knurl 6, and the external diameter of described secondary annular flange flange 5 is less than the external diameter of annular flange flange 3.Wherein, described annular knurl 4, secondary annular knurl 6 are strip and are evenly distributed on respectively on described annular flange flange 3, the secondary annular flange flange 5.
In the utility model specific embodiment, be connected through chamfering 7 between described secondary annular flange flange 5 and the annular flange flange 3.The end face that described secondary annular flange flange 5 is positioned at outside thread 11 1 sides is provided with buffering chamfering 8.
Claims (3)
1. two annular knurl formula bolt; Include bar portion, head, described bar portion is provided with outside thread, is outward extended with annular flange flange in the bar portion between outside thread and the head; The sidewall of described annular flange flange is provided with annular knurl; It is characterized in that: outwards also be extended with secondary annular flange flange in the bar portion between described annular flange flange and the outside thread, described secondary annular flange flange is provided with secondary annular knurl, and the external diameter of described secondary annular flange flange is less than the external diameter of annular flange flange.
