The internal wall of permanent-magnetism cavity is mounted with permanent-magnet. Driving axle of permanent-magnetism cavity is fixedly mounted with iron core. Transmission fork block can be slidingly sheathed at driving axle of spring cavity. The two driving axes at two sides of transmission fork block are respectively sheathed a sliding spring base whose outside driving axes are respectively fixed a push board, between which and spring base, there is a spring. The present utility has a simple structure and can be widely used in bistable switch device.
Description
Technical field
The utility model relates to a kind of switching mechanism, is a kind of manual bisteady-state fast turnover mechanism specifically.
Background technology
In the power switch hydraulic operating mechanism, to use liquid transition mechanism.When the hydraulic system decompression need start reserve arrangement, generally by manual operation, but also be easy to the intermediateness that half point narrows occur during manual operation, cause branch, combined floodgate accident.My another patent " a kind of permanent magnet switch operating mechanism " (patent No.: CN97233462.9) disclose a kind of electronic operating mechanism, be stabilized in branch after the action of operating mechanism is finished, close two states, solved the action problem that half point narrows preferably.But because this mechanism need utilize electric energy, can only maintain original state after having a power failure, can not use when having a power failure, application is restricted.
Summary of the invention
The purpose of this utility model provides a kind of manual bisteady-state fast turnover mechanism that does not need electric energy, can satisfy manual switch use in emergency circumstances.
For achieving the above object, the utility model adopts following technical scheme:
Manual bisteady-state fast turnover mechanism described in the utility model comprises housing and is inserted into driving shaft in the housing slidably, the shift fork piece is installed on the driving shaft, the shift fork piece is connected with manual shift fork, have the dividing plate vertical in the housing with driving shaft, dividing plate is separated into permanent magnetism chamber and spring cavity with housing, be installed with permanent magnet on the inwall in permanent magnetism chamber, fixed installation is cored on the driving shaft in the permanent magnetism chamber; The shift fork piece is sleeved on the driving shaft in the spring cavity slidably, and each suit one spring base slidably respectively fixedly mounts a push pedal on the driving shaft of shift fork piece both sides on the driving shaft in the outside of spring base, between spring base and the push pedal spring is installed.
Above-mentioned housing is cylindric, and permanent magnet is circular, and iron core is cylindric.
On the driving shaft between shift fork piece and the spring base, respectively fixedly mount a positioning block.
Housing also can be for square, and permanent magnet is a strip, and iron core is square.
After adopting technique scheme, the utlity model has following advantage:
(1), simple in structure, reliable, do not need electric energy, can be widely used in the various bisteady-state fast turnover mechanisms;
(2), adopt spring energy-storage principle switch operating state, the initial actuating of mechanism is fast, can satisfy the fast requirement of starting velocity.
(3), adopt the action of permanent magnet assurance mechanism remain on either-or bistable state state at last, the half point of having avoided effectively occurring easily in the manual operation state that narrows reduces operating accident.
Description of drawings
Accompanying drawing is the cutaway view of an embodiment of the present utility model.
Embodiment
As shown in drawings, manual bisteady-state fast turnover mechanism described in the utility model, comprise housing 1 and be inserted into driving shaft 2 in the housing 1 slidably, housing 1 is cylindric, two ends have the end cap of sealing, the centre of housing 1 also has a dividing plate 4 vertical with driving shaft 2, and this dividing plate 4 is separated into permanent magnetism chamber 11 and spring cavity 12 with housing 1, and driving shaft 2 passes dividing plate 4 and end covers at two sides is inserted in the housing 1 slidably.The fixed-site that is arranged in permanent magnetism chamber 11 on the driving shaft 2 is equipped with columned iron core 6, and the diameter of this iron core 6 can move back and forth it with driving shaft 2 greater than driving shaft 2, the length width less than permanent magnetism chamber 11 in permanent magnetism chamber 11; Be installed with the permanent magnet 5 of ring-type on the inwall in permanent magnetism chamber 11, the internal diameter of permanent magnet 5 is slightly larger than the diameter of iron core 6, makes iron core 6 not interrupted when moving.The centre position that is arranged in spring cavity 12 on the driving shaft 2 is set with shift fork piece 3 slidably, and shift fork piece 3 is connected with manual shift fork 15, and the both sides of shift fork piece 3 respectively are provided with a spring base 7,8, and spring base 7,8 also is to be sleeved on slidably on the driving shaft 2; The arranged outside of spring base 7 has push pedal 10, the arranged outside of spring base 8 has push pedal 11, push pedal 10,11 is fixedly set on the driving shaft 2, on the driving shaft 2 between spring base 7,8 and the push pedal 10,11, be respectively installed with spring 9,12, locate for the ease of spring, also be provided with the groove of ring-type in spring base 7,8 or push pedal 10,11, spring 9,12 is arranged in these grooves.
In addition, on the driving shaft 2 between shift fork piece 3 and the spring base 7,8, respectively fixedly mount a positioning block 16,17, can avoid the spring return excessive like this.
Certainly, housing 1 also can be the square tube shape, and permanent magnet is a strip, and iron core is square.
In initial condition, because iron core 6 is subjected to the magneticaction of permanent magnet 5, iron core 6 must be positioned at a side in permanent magnetism chamber 11.As shown in drawings, when needs conversion work state, handle shift fork l5 promotion shift fork piece 3 its strength that overcomes spring 9 is moved to the left, this moment, spring 9 was compressed, and the spring 9 at rear is discharged gradually; But the magneticaction that is subjected to permanent magnet 5 owing to iron core 6 is bigger, and when setting in motion, driving shaft 2 does not move thereupon, and just spring 9 is compressed; When shift fork piece 3 moves to certain position, when energy stored is enough big in the spring 9, the magnetic force promotion driving shaft 2 that the elastic force of spring 9 overcomes permanent magnet 5 moves to the left, after iron core 6 is crossed permanent magnet 5 centers, the magnetic force direction that acts on the iron core 6 is reversed, consistent with the elastic force direction of spring 9, two kinds of strength promote driving shaft 2 fast moving to the left jointly, at this moment, even shift fork piece 3 stop motions, iron core 6 also can continue terminal direction motion to the left under the energy storage power effect of spring 9, up to the left end that is positioned at permanent magnetism chamber 11.Afterwards, because the magnetic force of 5 pairs of iron cores 6 of permanent magnet exists all the time, before manually reversing, iron core 6 is positioned in the left side in permanent magnetism chamber 11 all the time next time.
The course of work of reverse turn operation is not described in detail in this with top identical once more.
This device efficiently solves misoperation and mechanism's slow motion accident of pausing and causing in the middle of the man-operating mechanism operation.
