Specific implementation mode
For the technology contents of technical solution, construction feature, the objects and the effects are described in detail, below in conjunction with specific reality
It applies example and attached drawing is coordinated to be explained in detail.
Referring to Fig. 1, this embodiment describes a kind of interlocking mechanisms applied to permanent-magnet breaker, which is characterized in that packet
Include change-over switch 1, lower bracket 2, axle sleeve 3, organization soleplate 4, upper bracket 5, unilateral bearing 6, driving lever 7, operating shaft 8, follower lever
9, rotor 10, isolation baffle plate 11, guide plate 12；
Here 1 is please see Figure, organization soleplate can be generally vertically arranged, described for fixing other component based on it
Organization soleplate can be fixed or with the plate of installation permanent-magnet breaker Switch main body for one block of plate thereon.The operating shaft is worn
Organization soleplate is crossed, is arranged perpendicular to organization soleplate, one end of the operating shaft switchs this by connecting bushing and permanent-magnet breaker
A unilateral bearing is fixed in shaft linkage on body, the end of operating shaft, and the other end of operating shaft is also fixed with driving lever, actively
The other end of bar and one end of follower lever are hinged, and the other end of follower lever is also hinged with rotor, and the other end and the conversion of rotor are opened
The main shaft linkage shut drives change-over switch movement, guide plate, the guide plate and mechanism is additionally provided on the organization soleplate
Bottom plate is vertical, and the through-hole for allowing isolation baffle plate to pass through is additionally provided on the guide plate；The isolation baffle plate passes through on guide plate
Pilot hole, then rotor and follower lever are hinged.Pass through above-mentioned design, when operating shaft is rotated, permanent-magnet breaker
Switch can achieve the effect that move synchronously with the rotor of change-over switch, and the on/off switch of permanent-magnet breaker switch can pass through conversion
Switch display, for example, the electric signal on change-over switch is converted into optical signal, to play indicative function, such as：Turn when separating brake
Changing switch, location A, red light light again；When combined floodgate, because the movement of operating shaft drives double leval jib movement, double leval jib that conversion is driven to open
Pass turns to B location, and green light lights.To play electrical indicative function.Play the current permanent-magnet breaker switch work shape of instruction
The effect of state, staff can be known clearly the working condition of electric switch by instruction, avoid the generation of risky operation
And casualties.
And in further embodiment, our isolation baffle plate 11 is long strip type, and one end is provided with sliding groove, follower lever
One end articulated shaft is also connect with sliding block, and the length of sliding groove is more than the width of sliding groove, and the middle part of sliding block is narrow to be positioned over
In sliding groove, the width design that end is then more than sliding groove not falling out, and the sliding block can slide in sliding groove.Figure
2 illustrate the active state of the articulated shaft and sliding block different from the follower lever of Fig. 1, and user is driven actively by rotation process axis
When bar, the sliding block connected on follower lever can apply active force to sliding groove, drive isolation baffle plate in the vertical direction
It is moved.As shown in the figure, the other end of isolation baffle plate further includes limiting section, and the limiting section may include and other component
Reach the various parts of pairing lock or limit effect, such as bolt, buckle, latch, hook, limits the operation of interrupter
The activity of axis.Limiting section as shown in the figure is the baffle of bending, and the operating shaft for covering interrupter prevents user couple
It is operated.Interrupter is the safety isolated switch to charging compartment in killer switch.Pass through the setting of above-mentioned component
It prevents when breaker closing, to the non-secure operations of disconnecting switch, prevents personnel from entering live part, therefore this programme
The technique effect for the safety for improving permanent-magnetic switching breaker can be played.
In the embodiment shown in fig. 1, upper bracket 5 and 2 equal vertical mechanism bottom plate of lower bracket are arranged, the upper bracket 2, under
Holder 5 is located at operating shaft 8 over and under, and the upper bracket is mutually parallel with lower bracket, is mutually interconnected by supporting plate
Connect, be additionally provided on the supporting plate operating shaft by holder plate hole, upper and lower bracket and supporting plate are used to carry out operating shaft
It is preferably fixed, strengthen the stability of mechanism.After the completion of being assembled by said sequence, driving lever assembly is being grasped by certain angle
Make on axis, fixed with circlip (not shown), unilateral bearing is installed in operating shaft after fixing driving lever, will lead
It is transferred on unilateral bearing from connecting rod (can be multiple from connecting rod), is connect with change-over switch after assembling.On above-mentioned
The design of holder lower bracket and supporting plate can provide effective support so that operating shaft always works in level to operating shaft 8
On face.
In our embodiment, principal and subordinate's connecting rod can be double leval jib, and as shown in the figure, unilateral bearing is arranged in operating shaft
Outside.(up and down motion) drives the movement of shaft 14 to pass through connecting bushing when please see Figure the movement of 3 permanent magnet mechanism, 13 on/off switch here
15 drive the operating shaft movement of interlocking mechanism, operating shaft to drive double leval jib movement, the rotor on double leval jib and change-over switch main shaft
One end of connection drives change-over switch main axis, you can mechanical signal is converted to the electric signal on change-over switch.Meanwhile
The sliding groove of isolation baffle plate links with double leval jib, can be moved up and down by the guiding role of the pilot hole of guide plate.Breaker
When combined floodgate, isolation baffle plate moves downward, and to play the role of blocking the operating shaft on interrupter 16, realizes isolation interlocking.When
Also the fortune of the shaft on Switch main body can be driven when operating shaft in interlocking mechanism is moved as main movable part by connecting bushing
Dynamic, the rotation of shaft makes permanent magnet mechanism carry out on/off switch movement.Therefore, it accidentally grasps, uses to carry out closing a floodgate when preventing manual operation
Unilateral bearing avoids combined floodgate maloperation.In the particular embodiment, when interlocking mechanism is operated manually, operating shaft is in one-way shaft
(clockwise or counterclockwise) can only be moved under the action of holding toward a direction.Such as：It is separating brake direction counterclockwise, operating shaft is toward inverse
Unilateral bearing forced belt turn axis is past when hour hands rotate rotates counterclockwise；It is combined floodgate direction clockwise, at this time toward operation clockwise
When unilateral bearing do not stress, unilateral bearing dallies in operating shaft, operating shaft can not be driven to rotate, and therefore, permanent magnet mechanism can not
Closing by hand avoids closing a floodgate and accidentally grasp.It is designed by said mechanism, the setting of unilateral bearing enables to the mechanism can be only used for
Manual brake separating operates, it is therefore prevented that the harmful effect that manual false switching is brought.
It should be noted that although the various embodiments described above have been described herein, it is not intended to limit
The scope of patent protection of the present invention.Therefore, based on the present invention innovative idea, to embodiment described herein carry out change and repair
Change, or using equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it directly or indirectly will be with
Upper technical solution is used in other related technical areas, is included within the scope of patent protection of the present invention.
