Description
Technical field
The utility model belongs to technical field of fastening, is related to a kind of turn-break type anti-loosing and anti-assembling nut.
Background technology
With the high speed development of national economy, various field job facilities such as electric power tower, ultra-high-tension power transmission line, natural oil
The facilities such as feed channel, freeway guardrail to develop rapidly therewith, because the line length of field job facilities layout is wide, to maintenance
Work brings many difficulties, and maximum of which difficulty is exactly the stolen problem of component equipment.Due to current various electric power and
Hardware in plant equipment is all to be combined as a whole with angle steel, shaped steel by traditional bolt, nut, and this structure is easy to use
The general tools such as spanner, pipe wrench are dismantled, thus are also easy to be stolen.
For insufficient present on, people be made that it is miscellaneous change machine, some has also applied for patent, such as China
Patent document data discloses turn-break type protective jacket anti-assembling nut [application number：201520005421.3；Authorization Notice No.：
CN204458755U], it includes abnormity nut and protective jacket, and abnormity nut includes hexagonal position and cylinder position, hexagonal position
The inside is provided with hexagonal and disconnects groove, and fillet hexagon boss is provided with cylinder position, and be provided with two in protective jacket arranges in ladder circle
The protective jacket groove of cloth.
The turn-break type protective jacket anti-assembling nut of this kind of structure, by twisting off hexagonal position, make that spanner card can not be used after twisting off
Firmly nut and reach locking unloading functions.But the turn-break type protective jacket anti-assembling nut of this kind of structure, occur after vibrated
Loose phenomenon, nut is caused to unclamp, so that nut can be removed.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of turn-break type is locking anti-
Removing nut, the technical problem of solution are to make the anti-better function unloaded of nut anti-looseness.
The purpose of this utility model can be realized by following technical proposal：A kind of turn-break type anti-loosing and anti-assembling nut, including
Matrix nut and sliding are covered, and it is in the six of regular hexagon that described matrix nut, which includes the cylindrical portion of circular in cross-section and cross section,
Corner, there is broken part between described cylindrical portion and hexagonal portion, there is internal thread on the madial wall of described cylindrical portion, it is described
Cylindrical portion there is the annular gear edge that protrusion sets close to the one end in hexagonal portion, there is step on the madial wall of described sliding cover
Face, described cylindrical portion is located in sliding cover and described annular gear edge is resisted against on step surface, it is characterised in that described
Tight fit is fixed with support plug in cylindrical portion, and deep-slotted chip breaker is provided with the madial wall of described cylindrical portion, is set in described deep-slotted chip breaker
There are spring and ball, one end of described spring is resisted against in cylindrical portion, and the other end is resisted against on ball, in the work of spring force
Under, described ball has the trend for compressing support plug all the time.
When this turn-break type anti-loosing and anti-assembling nut combines, first spring and steel ball are put into the deep-slotted chip breaker of matrix nut madial wall
In, then support plug is tucked into matrix nut, steel ball and spring is positioned in deep-slotted chip breaker, then matrix nut by certain
Direction be tucked into sliding set in.During installation, matrix nut hexagonal portion outwardly, pins matrix nut and screws in bolt, then with pulling
Hand blocks the hexagonal portion on matrix nut, tightens matrix nut, when wrenching torque reaches certain value, the hexagonal on matrix nut
Portion is twisted into two parts, and is now installed.When implementing to dismantle, due to being cased with sliding cover outside matrix nut, when blocking cunning with spanner
When moving cover torsion, sliding cover just skids on the cylinder of matrix nut, matrix nut is not reversed, when the circle of matrix nut
During cylinder loose unloading vibrated, the steel ball in the built-in deep-slotted chip breaker of matrix nut is promoted and is pressed in support plug by spring, from
And support plug is pinned, this turn-break type anti-loosing and anti-assembling nut has dual locking unloading functions, and locking unloading functions are relatively reliable, locking
Unloading functions are good.
In a kind of above-mentioned turn-break type anti-loosing and anti-assembling nut, one end of described support plug has outwardly setting
Convex edge, the external diameter of described convex edge are more than the internal diameter of cylindrical portion.The setting of convex edge makes support plug not protrude fully into cylindrical portion
It is interior.
In a kind of above-mentioned turn-break type anti-loosing and anti-assembling nut, it is arranged at intervals with the lateral wall of described support plug some
Bar reinforcement, described reinforcement is along the axially arranged of support plug.The setting of reinforcement can improve cylindrical portion and consolidate with support plug
Firmness even.
In a kind of above-mentioned turn-break type anti-loosing and anti-assembling nut, described spring is column spring.
In a kind of above-mentioned turn-break type anti-loosing and anti-assembling nut, described spring and ball are made by metal material.
In a kind of above-mentioned turn-break type anti-loosing and anti-assembling nut, described support plug is made up of plastic material.
Compared with prior art, turn-break type anti-loosing and anti-assembling nut provided by the utility model has dual anti-loose unloading work(
Can, locking unloading functions are relatively reliable, and locking unloading functions are good；And this turn-break type anti-loosing and anti-assembling nut assembles, is easy for installation.
