Abstract
The invention relates to an easily demountable nut for a scale environment. The easily demountable nut comprises a nut body; the end face of one side of the nut body is lifted by one circle along a thread line so as to form a spiral end face; internal threads consistent with the internal threads of the nut body are formed on the inner sidewall of the spiral end face part; a step is formed between the tail end and the starting position of the spiral end face; the sidewall of the step is inclined from top to bottom to form a section, and an acute part on the inner side of the section is formed into a cutting edge. The cutting edge is formed on the inner side of the end face on one side of the nut and used for breaking scale in the external-thread groove of a bolt by cutting under the action of a spanner, and therefore, the nut is gradually moved outwards until being separated from the bolt. The easily demountable nut for the scale environment is relatively easy and convenient to demount, and therefore, the working efficiency can be improved.
Description
Technical field
The present invention relates to a kind of nut, specifically a kind of quick detachable nut for fouling environment.
Background technique
In Chemical Manufacture, component environment corrosivity is strong or have flowable materials, material dust to exist, and after regular screw threads link uses a period of time in the environment, bolt is understood corrosion or solid accumulation and forms incrustation.Iron rust during dismounting on bolt, incrustation hinder nut to rotate, and cause and are difficult to dismounting.Now generally adopt spray Rust preventative, sawed-off or oxy arc such as to cut off at the failure mode dismounting with hacksaw.But, run into threaded connector present position narrow or naked light occasion can not be employed, make hacksaw make not use or oxy arc can not use, and the threaded piece poor effect that Rust preventative is heavier to corrosion, make dismantlement work become abnormal difficult, dismantlement work efficiency is extremely low.
Summary of the invention
The object of this invention is to provide a kind of quick detachable nut for fouling environment, failure mode need not be taked under bolt corrosion or severe deposits situation namely detachable, and operation is easier to, and can increase work efficiency.
The present invention is achieved in that and comprises nut body, one side end face of nut body threadingly line lifting one is enclosed and forms spirality end face, the madial wall of spirality end face part has the internal thread consistent with the internal thread of nut body, step is formed between spirality end face end and initial position, mesa sidewall is obliquely installed formation tangent plane from top to bottom, and inside tangent plane, sharp parts forms cutting cutting edge.Time fastening, nut body planar ends is positioned at inner side workpiece pressing.During dismounting, use spanner rotating nut, be positioned at the spirality end face outwards movement in outside, in the outside thread groove incision fouling of sharp-pointed cutting edge opening's edge bolt, layer of scale is cut, make it destroy and loosen formation chip, continue you by the thread groove of fouling chip release bolt, thus nut is outwards moved gradually until depart from bolt.
For the cutting cutting edge reduced when nut moves enters the resistance of layer of scale, the angle between tangent plane and nut body radial cross section should at 30 ° ~ 60 °.This set, can make cutting cutting edge cut gradually from the bottom to top in fouling.
For convenience of chip removal, the tangent line that tangent plane favours nut body inner circle is arranged, and the angle α between the tangent line in tangent plane and threadingly line lifting direction is at 100 ° ~ 120 °.
The present invention is by arranging spirality end face in nut one side end face, make inside this side, form cutting cutting edge, therefore when dismantling, only under the effect of spanner, namely need carry out cutting damage by cutting edge mouth to the fouling in bolt outside thread groove, thus nut is outwards moved gradually until depart from bolt.Thus disassembling section is easier to, conveniently, can increase work efficiency, and this dismounting can not damages bolt, can be cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is along A-A line sectional view in Fig. 1.
Fig. 3 is Fig. 1 stereoscopic-state structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the technological scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, 2, 3, one side end face 7 of nut body 1 is plane structure, opposite side end face threadingly line 8 lifting one encloses and forms spirality end face 3, the madial wall of spirality end face 3 part has the internal thread consistent with the internal thread of nut body 1, step is formed between spirality end face 3 end and initial position, mesa sidewall is obliquely installed from top to bottom and forms tangent plane 4, and inside tangent plane 4, sharp parts forms cutting cutting edge 5.
For the cutting cutting edge reduced when nut moves enters the resistance of layer of scale, the angle between tangent plane 4 and nut body 1 radial cross section and end face 7 is at 30 ° ~ 60 °.
For convenience of chip removal, the tangent line that tangent plane 4 favours nut body inner circle 2 is arranged, and the angle α between the tangent line 6 in tangent plane 4 and threadingly line 8 lifting direction is at 100 ° ~ 120 °.
