Description
Technical field：
The utility model is related to a kind of nut, and in particular to a kind of eccentric lever type stop nut.
Background technology：
Threaded connection is that one kind is removably fixedly connected, and has the advantages that simple structure, connection reliability, is convenient to mount and dismount,
It is widely used in the connection areas such as mechanical engineering, precast construction.Threaded connection typically has self-locking performance, and nut and bolt head
Frictional force on the supporting surface in portion also has a locking effect, thus tighten it is latter as will not release.But make in shock and vibration or varying load
Under, and in high temperature or larger temperature change, the frictional force between screw thread can reduce or disappear moment, and connection may pine
It is dynamic, so needing exist for the stop nut that can be fastenedly connected.
Existing traditional anti-loose structure is strengthened between screw thread pair and related counterpart by increasing axial pre tightening force mostly
Frictional force is come locking, although with certain effect, but the temperature difference it is big, vibrate strong operating mode under still can produce pretightning force decline or
Nut such as releases at the phenomenon of locking failure.Therefore its reliability is relatively low, is not suitable for requirement occasion higher.
The content of the invention：
The purpose of this utility model is the weak point for solving existing stop nut, there is provided a kind of rational in infrastructure, connection
Reliable, anti-loosing effect is good, is convenient to mount and dismount, lower-cost eccentric lever type stop nut.
The utility model is achieved through the following technical solutions：
Eccentric lever type stop nut of the present utility model, including nut upper surface, nut lower surface, screwed hole, wherein
Nut upper end facial plane is orthogonal with the central shaft of screwed hole；Nut lower end facial plane threadingly hole axle to nut upper surface
There is interval in plane；Nut lower end facial plane is with nut upper end facial plane in the angle more than 0 ° less than 5 °.
The centre of form of eccentric lever type stop nut of the present utility model, the wherein central shaft of screwed hole and nut upper surface is not
Overlap；The central shaft of screwed hole is near the minimum side of nut thickness；Screwed hole is through nut upper surface and nut lower surface.
Eccentric lever type stop nut of the present utility model, wherein nut lower surface threadingly hole radially away from sideline set
It is equipped with fillet.
Eccentric lever type stop nut of the present utility model, wherein nut upper surface threadingly hole radially away from side
It is provided with some tightening screwed holes for extending through nut lower surface.
Eccentric lever type stop nut of the present utility model, wherein tightening screwed hole mutually match with tapered end holding screw
Close.
The beneficial effects of the utility model are：Rational in infrastructure, connection is reliable, anti-loosing effect is good, is convenient to mount and dismount, cost
Even if low, in the case where external force and temperature conditionss are changed greatly be not easy to release.

Specific embodiment：
The utility model is described further with reference to the accompanying drawings and detailed description：
Embodiment：Eccentric lever type stop nut, including nut upper surface 1, nut lower surface 2, wherein screwed hole 3, spiral shell
The plane of female upper surface 1 is orthogonal with the central shaft of screwed hole 3；The plane of nut lower surface 2 threadingly hole 3 axially with nut upper end
There is interval in the plane of face 1；The plane of nut lower surface 2 is with nut upper surface 1 in the angle more than 0 ° less than 5 °；In screwed hole 3
Heart axle is misaligned with the centre of form of nut upper surface 1；The central shaft of screwed hole 3 is near the minimum side of nut thickness；Screwed hole 3 is passed through
Wear nut upper surface 1 and nut lower surface 2；Nut lower surface 2 threadingly hole 3 radially away from sideline be provided with fillet 6；Nut
Upper surface 1 threadingly hole 3 radially away from side be provided with some tightening screwed holes 4 for extending through nut lower surface 2；Tightening
Screwed hole 4 is worked in coordination with tapered end holding screw 5.
When using, as shown in Figure 3：The screwed hole 3 of eccentric lever type stop nut screws in bolt 11, and fillet 6 is contacted first
The upper surface 9 of upper member 7, fillet 6 can be used to reduce frictional force and prevent from scratching mating surface, under the contact lower member 8 of bolt 11
End face 10.
As shown in Figure 4：Continue to apply moment of torsion to eccentric lever type stop nut, until nut lower surface 2 and upper member 7
Upper surface 9 is overlapped, the further tensile bolt 11 of pretightning force for producing eccentric lever type stop nut, and now bolt 11 is produced
Flexural deformation in elastic deformation area, bolt 11 is existed and shunk along axis and to the trend of center resilience；Continuation is applied to nut
Plus moment of torsion, nut is rotated 1/4 to 1/2 and enclose, secondary pretension is implemented to bolt 11, and lock tapered end holding screw 5, now the spiral shell
The locking work of line connection is fully completed.
