Description
Technical field
The utility model relates to a kind of fastening piece, be specifically related to a kind of can the bolt assembly of axial stretching.
Background technique
At present, some multiple products be stacked together or parts normally realize its secure fit each other by the bolt assembly be made up of the first bolt and the second bolt, in the prior art, interior hexagonal groove is all offered on the nut of described first bolt and on the nut of the second bolt, the bar portion of the first bolt is provided with outside thread, in the bar portion of the second bolt, correspondence is provided with the inner bolt hole matched with described outside thread, such vibrational power flow, no matter people rotate the dismounting that the first bolt or the second bolt all can realize bolt assembly, but because the bar portion of the first bolt and the bar portion of the second bolt are all a fixing length, cannot axial stretching, therefore when described bolt assembly be used to lock join different product time, the first bolt of different length specification and the second bolt is often needed to come adaptive, thus cause the specification of bolt assembly of a great variety, lack versatility.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of can the bolt assembly of axial stretching, it is applicable to lock joins various different product, has good versatility.
For achieving the above object, the utility model provide a kind of can the bolt assembly of axial stretching, include the first bolt and the second bolt, interior hexagonal groove is all offered on the nut of described first bolt and on the nut of the second bolt, the bar portion of the first bolt is provided with outside thread, also connecting sleeve is provided with between described first bolt and the second bolt, one end correspondence of described connecting sleeve is provided with the inner bolt hole matched with described outside thread, the bar portion of described second bolt offers the through hole axially extended internally, the other end of described connecting sleeve is arranged in described through hole, described through hole is also evenly distributed in multiple axial slip groove, on described connecting sleeve corresponding be provided with setting-in to enter in described axial slip groove and can on described axial slip groove the convex tendon of axial slip, described convex tendon is also linearly evenly equipped with multiple positioning groove in the axial direction, in the bar portion of described second bolt, corresponding being equipped with can form the limit stoper of location fit with one of them positioning groove, described limit stoper includes steel ball, spring and countersunk bolts, the bar portion of described second bolt offers and holds described steel ball, the radial cavity of spring and countersunk bolts, and the through hole that described radial cavity and the second bolt shank axially extend internally connects, described steel ball correspondence is positioned at the radial inner end of radial cavity, described countersunk bolts is spirally connected and is fixed on the radial outer end of radial cavity, described spring is between steel ball and countersunk bolts, the two ends of spring are formed with steel ball and countersunk bolts respectively and abut, and described steel ball can enter in one of them positioning groove to form location fit by setting-in under the action of the spring.
The beneficial effects of the utility model are: adopt said structure, because described first bolt is spirally connected to be fixed on one end of connecting sleeve, between connecting sleeve and the second bolt then by the fitted shaft of axial slip groove and convex tendon to telescopic slide, and after axial stretching, location fit is formed by one of them positioning groove on the limit stoper on the second bolt shank and connecting sleeve, so just the bolt assembly after combining is made to have good axial stretching function, be applicable to lock and join various different product, possess versatility.
The cross section that the utility model can be set to described axial slip groove and convex tendon is further swallowtail shape.It is more firm that such setting can make described axial slip groove coordinate with the connection of convex tendon, effectively prevents from getting loose.
Accompanying drawing explanation
