Abstract

The utility model proposes a kind of detachable mounted bolt, including nut, stud, screw thread, hexagonal groove, cross recess and outage, described stud be shaped as cylinder, the upper end of described stud is cylinder, is provided with screw thread outside bottom, and the top of described stud is provided with nut, described nut be shaped as six prisms, described nut upper surface is provided with hexagonal groove, is provided with cross recess below described hexagonal groove, and two opposite side of described nut are provided with outage.This utility model greatly reduces the probability that cannot dismount because finding the operation instrument of coupling, also to some extent solves because stripped thread causes the difficulty that cannot dismount, it is to avoid nut internal water accumulation causes the problem got rusty simultaneously.

Description

A kind of detachable mounted bolt
[technical field]
This utility model relates to outdoor machinery, mining machinery, the technical field of chemical industry equipment part connection fastening, particularly A kind of technical field of detachable mounted bolt.
[background technology]
Bolt head is generally set to hexagon, tetragon or octagon, and above-mentioned bolt is when dismounting, because instrument limit System, and dismounting cannot be realized, the space that the assembling tool of Hexagonal jacket, corner sleeve or anistree sleeve takies is relatively big, Ren Men Using middle needs bolt to have performance rapidly and efficiently and effect, people done in bolt product such as cross screw bolt, interior six The improvement that corner bolt etc. is useful, other medium-sized plant equipment such as sudden and violent lorry, machine for unloading coal, long-term wind and weather Exposure to Sunlight, easily make Exerted bolt on equipment, the generation rust corrosion such as girder, flange attachment bolt, material property declines, and these bolts are to tearing open at present The tool demands of dress bolt is single and selectivity is bad, and that the most easily brings in use is passive, proposes a kind of detachable mounted Bolt.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed that a kind of detachable mounted bolt, no The most well solve the probability that cannot dismount because the operation instrument of coupling cannot be found, but also solve owing to hydrops draws The problem got rusty risen.
For achieving the above object, the utility model proposes a kind of detachable mounted bolt, including nut, stud, screw thread, Hexagonal groove, cross recess and outage, described stud be shaped as cylinder, the upper end of described stud is smooth cylindrical Body, is provided with screw thread outside bottom, the top of described stud is provided with nut, described nut be shaped as six prisms, described nut Upper surface is provided with hexagonal groove, is provided with cross recess below described hexagonal groove, and two opposite side of described nut are provided with discharge opeing Hole.
As preferably, described hexagonal groove be shaped as regular hexagon, the center of described hexagonal groove and the axis of stud Overlapping, the degree of depth of described hexagonal groove is equal to the 1/2 of nut stage body height.
As preferably, the center of described cross recess and the dead in line of stud, described cross recess is positioned at nut stage body At the 1/3 of height.
As preferably, the axis of described outage is perpendicular to the axis of stud, and described outage is positioned at cross recess Liang Ge branch on nut opposite side is connected.
The beneficial effects of the utility model: this utility model is by having hexagonal groove in the inside of nut and cross is recessed Groove, it is possible to mate multiple operation instrument, screw is dismounted by the mode selecting most convenient to carry out, and greatly reduces because looking for The probability that cannot dismount to the operation instrument of coupling, also to some extent solves because stripped thread causes dismounting simultaneously Difficulty.And run through in the branch of cross recess and have outage, it is to avoid nut internal water accumulation causes the problem got rusty.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of this utility model a kind of detachable mounted bolt;
Fig. 2 is the top view of this utility model a kind of detachable mounted bolt;
Fig. 3 is the profile of the nut of this utility model a kind of detachable mounted bolt.
In figure: 1-nut, 2-stud, 21-cylinder, 3-screw thread, 4-hexagonal groove, 5-cross recess, 6-discharge opeing Hole.
[detailed description of the invention]
Refering to Fig. 1, Fig. 2 and Fig. 3, this utility model one detachable mounted bolt, including nut 1, stud 2, screw thread 3, Hexagonal groove 4, cross recess 5 and outage 6, described stud 2 be shaped as cylinder, the upper end of described stud 2 is smooth Cylinder 21, is provided with screw thread 3 outside bottom, the top of described stud 2 is provided with nut 1, described nut 1 be shaped as six ribs Post, described nut 1 upper surface is provided with hexagonal groove 4, is provided with cross recess 5, the two of described nut 1 below described hexagonal groove 4 Individual opposite side is provided with outage 6.Described hexagonal groove 4 be shaped as regular hexagon, the center of described hexagonal groove 4 and stud 2 Dead in line, the degree of depth of described hexagonal groove 4 equal to nut 1 stage body height 1/2.The center of described cross recess 5 and spiral shell The dead in line of post 2, described cross recess 5 is positioned at the 1/3 of nut 1 stage body height.The axis of described outage 6 is perpendicular to spiral shell The axis of post 2, described outage 6 is connected with the Liang Ge branch being positioned on nut 1 opposite side of cross recess 5.
Utility model works process:
Bolt in the course of the work, during installation, is penetrated connected workpiece by this utility model one detachable mounted bolt Hole in, according to the restriction of working place, corresponding select die nut or Phillips screwdriver that it is fastened.Dismounting spiral shell During bolt, first-selection flat mouth screwdriver or cross can dismount this bolt in implementing to be inserted in cross recess 5;When stripped thread occurs, Coordinating hexagonal groove 4 can also dismount this bolt with instruments such as spanner, box spanner, inner hexagon spanners, multiple types of tools all can be complete Become dismantlement work.Being provided with outage 6 in nut 1, when having hydrops in hexagonal groove 4, hydrops can be arranged by outage 6 timely Go out, greatly reduce the probability that cannot dismount because the operation instrument of coupling cannot be found, solve the most to a certain extent simultaneously Because stripped thread causes the difficulty that cannot dismount, it is to avoid nut internal water accumulation causes the problem got rusty.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality Scheme after type simple transformation belongs to protection domain of the present utility model.
