Difference, while axial tensile-strength is relatively low, when by larger torque force or axial tension, is susceptible to support swivel nut and pine occurs
Dynamic phenomenon cannot meet the cavity proximate matter having higher requirements to connection fastening strength.
Utility model content
The purpose of this utility model is exactly that can be effectively improved anti-to solve above-mentioned deficiency and to provide one kind simple in structure
Turning power and axial tensile-strength greatly enhance the connection tightness with cavity proximate matter, are very suitable for many types of lumen type
The crowded expanding swivel nut of the cavity proximate matter of material.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
Cavity proximate matter is with expanding swivel nut is squeezed, it is made of cylinder, and the cylinder is integrally cylindrical, at cylinder rear portion
It is provided with annular convex platform on lateral wall, locking teeth is provided on the lateral wall of the cylinder front, in locking teeth and annular convex platform
Between cylinder lateral wall on be provided with antiturning pitch, the front end of cylinder is provided with boss, is opened on the lateral wall of the boss
Equipped with locking annular groove, centre bore is offered in the inside of cylinder, crowded swollen taper hole is offered in the rear portion of cylinder.
It is provided with internal thread on the madial wall in the body centre hole.
The internal thread is located at the front and rear of body centre hole madial wall.
The centre bore connects with crowded swollen taper hole.
The antiturning pitch is made of 1 ~ 3 circle.
The cross section of the locking annular groove is wedge shape.
The cross section of the locking annular groove is rectangle.
The locking teeth is rectangular teeth.
The locking teeth is annular knurl tooth.
The antiturning pitch is annular knurl tooth.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：Locking teeth and annular convex platform it
Between cylinder lateral wall on be provided with antiturning pitch, by antiturning pitch holding in the second through hole of cavity proximate matter cavity inner wall,
It is locked with cavity inner wall, to substantially increase the connection fastening strength of this swivel nut and cavity proximate matter so that its anti-twisting property
It is increased dramatically, plays good anti-rotation effect, be very suitable for inside support and the installation external zero of cavity proximate matter
Component is used.It is embedded in the cavity proximate matter lower wall at third through-hole by locking teeth, to further improve this swivel nut
Anti-rotation effect；Cavity proximate matter at third through-hole be squeezed deform be partially embedded into locking annular groove in, from
And effectively increase the axial tensile capacity of this swivel nut；By to squeeze swollen taper hole carry out squeeze it is swollen, make annular convex platform expand outward and
First through hole is interference fitted, and is locked, to further improve axial tensile-strength.
