Abstract
A kind of flange fixation kit comprising flange and the bolt being mounted on the flange, the flange are equipped with threaded hole, and the bolt includes the second threaded portion of the first threaded portion closed with the corresponding threaded holes and protrusion first threaded portion.So set, bolt can be stably mounted on flange by the cooperation by the first threaded portion and threaded hole.
Description
Technical field
The present invention relates to a kind of flange fixation kits, belong to connector technical field.
Background technique
Traditional bolt and flange is fixed with two ways, and one kind is welded type, and another kind is forced.
It please join shown in Fig. 1 and Fig. 2, in the fixed form of welded type, via hole 11 ' is provided on flange 1 ', bolt 2 ' passes through
The rear end of via hole 11 ', bolt 2 ' is fixed by welding on flange face.However, each bolt 2 ' has in this fixed form
Symmetrical two weld seams, need to put into welding equipment and positioning fixture for welding.In addition, flange face can be generated due to welding deformation
Deformation and be difficult to ensure verticality after bolt welding relative to flange face.
It please join shown in Fig. 3 and Fig. 4, in forced fixed form, aperture 11 ", the root of bolt 2 " are opened on flange 1 "
Using spline structure 3 ".It is interference fitted by 2 " root of bolt, indentation flange 1 " is fixed.However, in this fixed form
In, since aperture 11 " and the spline structure 3 " of 2 " root of bolt are interference fitted, to the size essence of aperture 11 " He spline structure 3 "
Degree control requires high, increase manufacturing cost.The process of press in of bolt 2 " needs used device to the more demanding of pressing-in force to protect
Demonstrate,prove stable pressing-in force.In addition, due to generating plastic deformation, bolt 2 " during transportation is easy after bolt 2 " is pressed into
It falls.When installing nut, bolt 2 " is easy to produce the rotation relative to flange 1 ".
Summary of the invention
The purpose of the present invention is to provide a kind of flange fixation kits for being relatively low cost and easy to installation.
To achieve the above object, the present invention adopts the following technical scheme: a kind of flange fixation kit comprising flange and
The bolt being mounted on the flange, the flange are equipped with threaded hole, and the bolt includes the closed with the corresponding threaded holes
Second threaded portion of one threaded portion and protrusion first threaded portion.
Technical solution as a further improvement of that present invention, the screw thread side of first threaded portion and second threaded portion
To opposite.
Technical solution as a further improvement of that present invention, the threaded hole have levogyrate inner thread, first screw thread
Portion is equipped with the sinistral external thread matched with the levogyrate inner thread.
Technical solution as a further improvement of that present invention, the threaded hole have dextrorotation internal screw thread, first screw thread
Portion is equipped with the dextrorotation external screw thread matched with the dextrorotation internal screw thread.
Technical solution as a further improvement of that present invention, the thickness of of length no more than flange of first threaded portion
Degree.
Technical solution as a further improvement of that present invention, the bolt include the rotation for being resisted against the side of the flange
Portion.
The other side of the flange is protruded in technical solution as a further improvement of that present invention, second threaded portion.
Compared to the prior art, flange of the invention is equipped with threaded hole, and the bolt includes closing with the corresponding threaded holes
The first threaded portion and protrusion first threaded portion the second threaded portion, pass through the cooperation energy of the first threaded portion and threaded hole
It is enough that bolt is stably mounted on flange, it is relatively low cost and easy to install.

Specific embodiment
It please join shown in Fig. 5 to Fig. 8, present invention discloses a kind of flange fixation kits 100 comprising flange 1 and installation
Bolt 2 on the flange 1.The flange 1 is equipped with threaded hole 11, and the bolt 2 includes matching with the threaded hole 11
The first threaded portion 21 and protrusion first threaded portion 21 the second threaded portion 22.
First threaded portion 21 is opposite with the hand of spiral of second threaded portion 22.In a kind of embodiment party of the invention
In formula, the threaded hole 11 has levogyrate inner thread, and first threaded portion 21 is equipped with and matches with the levogyrate inner thread
Sinistral external thread.In another embodiment of the invention, the threaded hole 11 has dextrorotation internal screw thread, first screw thread
Portion 21 is equipped with the dextrorotation external screw thread matched with the dextrorotation internal screw thread.Of length no more than method of first threaded portion 21
The thickness of orchid 1.
The bolt 2 includes the rotating part 23 (such as hexagonal flange) for being resisted against the side (such as left side) of the flange 1.
Protrude the other side (such as right side) of the flange 1 in second threaded portion 22.
When assembling, after bolt 2 passes through the threaded hole 11 of flange 1, application torque at the rotating part 23 is got the jump on by torsion,
First threaded portion 21 of 2 root of bolt is screwed with threaded hole 11.So set, being connected through a screw thread, guarantee in transportational process
Bolt 2 will not fall off, and assembling, which only needs one torque is robbed, achieves that, no longer needs to investment other equipment, saves cost；In addition,
It is connected through a screw thread, since screw thread has very well to neutrality, when assembly ensure that bolt 2 and the verticality of flange face are wanted well
It asks.When the second threaded portion 22 of bolt 2, which matches other flanges, is installed, the spiral shell with the cooperation of the second threaded portion 22 need to be only tightened
Female (not shown).Due to the hand of spiral of first threaded portion 21 and second threaded portion 22 on the contrary, so twisting
During tight nut, bolt 2 will not only be rotated relative to flange 1, but also can be more more stubborn tighter.
Above embodiments are merely to illustrate the present invention and not limit the technical scheme described by the invention, to this specification
Understanding should based on person of ordinary skill in the field, although this specification referring to the above embodiments to the present invention
Detailed description is had been carried out, still, those skilled in the art should understand that, person of ordinary skill in the field is still
Can so modify or equivalently replace the present invention, and all do not depart from the spirit and scope of the present invention technical solution and
It is improved, and should all be covered in scope of the presently claimed invention.
