Description
[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 the check bolt of easy disassembly.
[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, there is rust corrosion, material property decline, there are vibrations at some in girder, flange attachment bolt etc.
Occasion, the bolt for fastening often loosens, and causes connection to disengage, and machine failure even causes security incident, makes for this
Make and can become extremely urgent by the most anti-loosening bolt, it is proposed that the check bolt of a kind of easy disassembly.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed that the locking spiral shell of a kind of easy disassembly
Bolt, well solves the probability that cannot dismount because finding the operation instrument of coupling, due to getting rusty of causing of hydrops
Problem, and solve the bolt looseness that the extrinsic factor such as vibrations cause, it is ensured that bolted steadiness.
For achieving the above object, the utility model proposes the check bolt of a kind of easy disassembly, including nut, stud,
Screw thread, hexagonal groove, cross recess and elastic washer, described stud be shaped as cylinder, outside the bottom of described stud
Being provided with screw thread, the top of described stud is provided with nut, described nut be shaped as six prisms, described nut upper surface offers six
Angle groove, is provided with cross recess below described hexagonal groove, the lower surface of described nut is provided with elastic washer, described elastic washer
Inside offering several endoporus, described endoporus is distributed in uniform circular centered by stud.
As preferably, the lower surface circle distribution of described nut have several fastening teeths, the number of described fastening teeth be 6～
8, the upper end of described fastening teeth is cylindrical, and bottom is truncated cone-shaped or cone, and described fastening teeth matches with endoporus,
The length of described fastening teeth is less than the degree of depth of endoporus.
As preferably, described hexagonal groove be shaped as regular hexagon, the centrage of described hexagonal groove and the axle of stud
Line overlaps, and the degree of depth of described hexagonal groove is equal to the 1/2 of nut stage body height.
As preferably, two opposite side of described nut are provided with outage, and the cross sectional shape of described outage is circular, institute
State outage to be connected with the Liang Ge branch being positioned on nut opposite side of cross recess.
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, 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, by can be after bolt be screwed in screw, and elastic washer and the cooperation of fastening teeth, make nut
And increasing friction force between bolt, it is to avoid loosening easily of bolt, it is ensured that bolted steadiness.
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 the check bolt of a kind of easy disassembly of this utility model；
Fig. 2 is the top view of the check bolt of a kind of easy disassembly of this utility model.
In figure: 1-nut, 2-stud, 3-screw thread, 4-hexagonal groove, 5-cross recess, 6-elastic washer, 11-outage,

[detailed description of the invention]
Refering to Fig. 1 and Fig. 2, the check bolt of a kind of easy disassembly of this utility model, including nut 1, stud 2, screw thread 3,
Hexagonal groove 4, cross recess 5 and elastic washer 6, described stud 2 be shaped as cylinder, outside the bottom of described stud 2
Being provided with screw thread 3, the top of described stud 2 is provided with nut 1, described nut 1 be shaped as six prisms, described nut 1 upper surface is opened
Being provided with hexagonal groove 4, be provided with cross recess 5 below described hexagonal groove 4, the lower surface of described nut 1 is provided with elastic washer 6,
Offering several endoporus 61 in described elastic washer 6, described endoporus 61 is distributed in uniform circular centered by stud 2.Described
The lower surface circle distribution of nut 1 has several fastening teeths 12, the number of described fastening teeth 12 to be 6～8, described fastening teeth 12
Upper end be cylindrical, bottom is truncated cone-shaped or cone, and described fastening teeth 12 matches with endoporus 61, described fastening teeth
The length of 12 is less than the degree of depth of endoporus 61.Described hexagonal groove 4 be shaped as regular hexagon, the centrage of described hexagonal groove 4
With the dead in line of stud 2, the degree of depth of described hexagonal groove 4 is equal to the 1/2 of nut 1 stage body height.Two of described nut 1 right
