Abstract
The screw bolt with nuts in the two end include screw bolt end plane, head nut, inward concave hidden nut, screw bolt, nut, spanner, inner hexagon spanner and Philips driver. The screw bolt has two nuts in its two ends, and its tail end has inward concave hidden nut without affecting the use of the thread on the screw bolt. The inward concave hidden nut may be in the shape of inward concave hexagonal slot or crossed slot for matching the inner hexagon spanner and the Philips driver separately. The present invention makes it possible to complete the screw-in and screw-out job in one work plane only.
Description
Technical field
The present invention relates to fastening piece, particularly be the bolt that all there is nut at a kind of head and the tail two ends.
Background technique
As everyone knows, one bolts has only head one end that a nut is arranged, and the diameter of nut is greater than the diameter of bolt shank, nut lives fastener except extruding and from the position of a side fixing bolt, more important role is to drive bolt to be in fastening or unpack procedure under the pressure turn of wrench instrument.Theoretically, under the motionless prerequisite of nut location, have only the turn nut just can reach purpose fastening or that take one group of bolt apart; On motionless basis, nut position, have only the turn nut just can finish task fastening or that take one group of bolt apart conversely speaking.In practical operation, people rotate in one direction synchronously for fear of bolt shank and nut, must on two relative working surfaces, block nut and nut respectively simultaneously with two spanners, but the effective means that two spanners of this usefulness " are protected " is not mutually usually accomplished because of various objective factors on two different operating faces.For example bolt shank and nut " are worked day and night " in fastening one group of bolt process, are inconvenient to use spanner and the working surface at nut place is narrow; For example take apart one group of wall rise pipe during bolt because of get rusty or reason such as greasy dirt midway bolt shank and nut " work day and night ", suffer from again to make and do not use effective tool.In sum, no matter fastening or take one group of bolt apart and need all that the employing instrument carry out " protecting mutually " on two relative working surfaces, therefore people wish to have and a kind ofly can just realize fastening on a working surface or take bolt apart and can overcome bolt shank and " work day and night " fastening piece of phenomenon of nut, but known at present, do not find setting as yet with this function.
Summary of the invention
In order to address the above problem, the invention provides the bolt that all there is nut at a kind of head and the tail two ends, its head nut is identical with the nut shape of general bolt, and purposes and effect are also identical.Its tail end nut adopts the form of the dark nut of indent, the dark nut of indent is recessed on the bolt tail end face, the dark nut of indent is recessed in the bolt shank diameter, and the dark nut of indent does not hinder the use of screw thread on the bolt shank, dark nut of indent and general wrench instrument coupling.The purposes and the effect of dark nut of indent and head nut are had any different, both not responsible extruding is lived fastener and from the task of a side fixing bolt position, only is responsible under the pressure turn of wrench instrument doing to cooperate with nut or tapped hole driving bolt and being in fastening or unpack procedure.When using the dark nut of indent, the thread rotary orientation on the bolt shank becomes left-handed thread, thus during clamping bolt for being rotated counterclockwise direction, be the dextrorotation veer when taking bolt apart, or sense of rotation when taking bolt fastening with use head nut antithesis.Block under the motionless situation of nut at the spanner of living, process fastening or that take bolt apart is solved on a working surface at nut place with the dark nut of wrench instrument turn indent.
To achieve these goals, the present invention adopts following technological scheme to implement: all there is the bolt of nut at the head and the tail two ends, and its head nut is identical with the nut shape of general bolt, and purposes and effect are also identical.Its tail end nut adopts the form of the dark nut of indent, and the dark nut of indent is recessed on the bolt tail end face, and the dark nut of indent is recessed in the bolt shank diameter, and the dark nut of indent does not hinder the use of screw thread on the bolt shank.The diameter of the corresponding bolt of the plane geometric shape of the dark nut of indent, adopt hexagonal shaped and two kinds of shapes of cross, the dark nut of indent of the above bolt of diameter 8mm is selected indent six square groove forms for use and is mated with interior six side's spanners, the dark nut of indent of the following bolt of diameter 8mm is selected indent cross recess form for use and is mated with Phillips screwdriver, and the dark nut of indent of diameter 8mm bolt can be selected any one form in indent six square grooves and two kinds of forms of indent cross recess for use.The purposes and the effect of dark nut of indent and head nut are had any different, both not responsible extruding is lived fastener and from the task of a side fixing bolt position, only is responsible under the pressure turn of wrench instrument doing to cooperate with nut or tapped hole driving bolt and being in fastening or unpack procedure.When using the dark nut of indent, the thread rotary orientation on the bolt shank becomes left-handed thread, thus during clamping bolt for being rotated counterclockwise direction, be the dextrorotation veer when taking bolt apart, or sense of rotation when taking bolt fastening with use head nut antithesis.Block under the motionless situation of nut at the spanner of living, the dark nut of turn indent can make process fastening or that take bolt apart solve on a working surface at nut place.Certainly, also can be conversely block the dark nut of indent with interior six side's spanners or Phillips screwdriver and make bolt shank keep motionless, being aided with spanner alive, to drive the nut turn fastening or take bolt apart.
The diameter of the corresponding bolt of the plane geometric shape of the dark nut of above-mentioned indent, adopt hexagonal shaped and two kinds of shapes of cross, both six square grooves of the indent on the solid and indent cross recess, its Dimensions is consistent with indent six square grooves and indent cross recess Dimensions on the NBS nuts.The dark nut of indent of the above bolt of diameter 8mm is selected indent six square groove forms for use and is mated with interior six side's spanners, the bolt shank diameter increases the also corresponding in proportion increase of indent six square groove sizes of the dark nut of indent on its bolt tail end face, and is one-to-one relationship with the interior six side's spanners that become sequence.The dark nut of indent of the following bolt of diameter 8mm is selected indent cross recess form for use and is mated with Phillips screwdriver.The dark nut of indent of diameter 8mm bolt can be selected any one form in indent six square grooves and two kinds of forms of indent cross recess for use.
The invention has the beneficial effects as follows: all there is the bolt of nut at the head and the tail two ends, broken bolton in the past or must be simultaneously when taking apart on two relative working surfaces tool using carry out the fixed mode of " protecting mutually ", process fastening or that take bolt apart can be solved on a working surface at nut place, and overcome bolt shank and the nut phenomenon of " working day and night ", make things convenient for operation, improved work efficiency.
