Abstract
The mechanical soft interlocking fixation with steel wire mode of omnipotent breaker, it includes lever, it is characterised in that：The force side of steel wire is locked around the pulley on lever with fixing piece, and the stress keyed end of the steel wire is opposing stationary with lever during lever rotation.The present invention changes force way and the position of interlocking steel wire, makes that it is equally loaded, extends the service life of steel wire.
Description
Technical field
It is specifically exactly to be related to the mechanical soft interlocking steel wire of omnipotent breaker the invention belongs to breaker mounting technique field
Fixed form is able to extend the service life of the soft interlocking of breaker mechanical.
Background technique
Mechanical interlocking in omnipotent breaker formula using more and more extensive, as omnipotent breaker combined type is from turn
The application of switch is changed, the mechanical life requirement of omnipotent breaker is also higher and higher, and the common mechanical service life needs up to 10000 times
More than.And the service life of corresponding mechanical interlocking is more important, but the service life of existing mechanical interlocking less than 1000 times, nothing
Method meets the requirement of omnipotent breaker combined type automatic change-over.As shown in Fig. 1, existing mechanical interlocking structure
Wire locking on axis, steel wire stress keyed end is rotated with lever rotation, and has moment stress friction, steel wire institute with axis
The keyed end that the movement pulling force of receiving concentrates on steel wire causes steel wire using fatigue, and the service life is unable to satisfy omnipotent breaker combination
The requirement of formula automatic change-over.
Summary of the invention
The purpose of the present invention is to the mechanical soft interlocking fixation with steel wire modes of existing omnipotent breaker to be easy to cause
Steel wire is provided a kind of mechanical soft interlocking fixation with steel wire mode of omnipotent breaker, is changed interlocking steel using the technological deficiency of fatigue
The force way of silk and position, make that it is equally loaded, improve the service life of steel wire, it is automatic to meet omnipotent breaker combined type
The requirement of change-over switch.
Technical solution
In order to achieve the above technical purposes, the mechanical soft interlocking fixation with steel wire mode of the omnipotent breaker that the present invention designs,
It includes lever, it is characterised in that：Steel wire force side is locked around the pulley on lever with fixing piece, the stress lock of the steel wire
Fixed end is opposing stationary with lever during lever rotation.
Further, the pulley is on axis, and axis is on lever.
Further, baffle is installed on axis and is located on the outside of pulley.
Further, for the lever through rotation axis on the substrate, fixing piece and axis are installed on one end of lever side by side,
The other end of lever is equipped with tension spring, and tension spring one end is on lever, and the other end is on substrate.Beneficial effect
The mechanical soft interlocking fixation with steel wire mode of a kind of omnipotent breaker provided by the invention, changes the stress of interlocking steel wire
Mode and position, make the stress keyed end of steel wire during lever rotation with the opposing stationary no friction of lever, steel wire stress into
Row split-up, is partially forced through the contact position that pulley is transferred to steel wire and pulley, and pulley makes to contact with lever rotation
Position uniformly changes, and makes to be transferred to steel wire uniform force on pulley, smooth, extends the mechanical soft interlocking steel of omnipotent breaker
The service life of silk.
Detailed description of the invention
Attached drawing 1 is the mechanical soft interlocking fixation with steel wire schematic diagram of existing omnipotent breaker.
Attached drawing 2 is the structural schematic diagram of the embodiment of the present invention 1.
Attached drawing 3 is the structural schematic diagram of the embodiment of the present invention 2.
Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be further described.
Embodiment 1
As shown in Fig. 2, separate unit when technical solution provided by the invention is for two omnipotent breaker mechanical interlockings
Structural schematic diagram, lever 1, by the dress of rotation axis 7 on the substrate 8, fixing piece 4 and axis 5 are installed on one end of lever 1 side by side,
The other end of lever 1 is equipped with tension spring 9, and for 9 one end of tension spring on lever 1, other end dress can make lever 1 rotate on the substrate 8
The rotation of moving axis 7 resets.2 force side of steel wire locks around the fixing piece 4 of the pulley 3 on lever 1, the steel wire 2 by force locking
It holds opposing stationary with lever 1 in 1 rotation process of lever.The pulley 3 is on axis 5, and axis 5 is on lever 1.
Baffle 6, which is installed on axis 5, is located at 3 outside of pulley.
In the present embodiment, the stress keyed end of steel wire 2 and opposing stationary in 1 rotation process of lever, no swing friction, pulley
3 are transferred to the part stress of steel wire 2 on pulley 3, and pulley 3 is with the stress in 1 rotation process of lever by steel wire 2 on pulley 3
Point makees even variation, makes 2 stress of steel wire more evenly, effectively extends the service life of steel wire 2.
Embodiment 2
