Structure.
Background technique
Spring energy-storage quick release mechanism is a kind of mechanical driving device, is mainly used on load ratio bridging switch at present,
And in load ratio bridging switch for transformer.The tap of different windings is connected in conversion in loaded situation, is become by changing
The turn ratio of depressor winding achievees the purpose that change transformer output voltage.Due to it is this conversion be usually phase step type quickly into
Row ground, so load ratio bridging switch all has the mechanism of a spring energy-storage quick release.
Early stage load ratio bridging switch mostly uses greatly oscillating rod type to cross dead point spring energy-storage quick release mechanism, and structure is excessively multiple
Miscellaneous, the accuracy of manufacture requires high, slightly to manufacture or assemble carelessness, though resulting in swing rod has crossed dead point, the quick machine of spring energy-storage
The problem of structure appearance does not discharge, causes burning for load ratio bridging switch.
For above situation, there is rifle bolt spring energy-storage quick release mechanism in the later period.It is stored up relative to dead point spring is crossed
Energy quick release mechanism, though rifle bolt spring energy-storage quick release mechanism has improvement on performance reliability.But rifle bolt spring
Energy storage quick mechanism borrow mostly M type oil immersed type switching switch circularly-eccentric sheave on lower slide box formula relieving mechanism, upper and lower two
Sliding box is slided each along 2 guide rails (amounting to 4 guide rails) of itself, and the outside of sliding box is arranged in claw for release cam, leads
Cause device volume big；Entire quick release mechanism input shaft and output shaft use concentric locking collar axle construction simultaneously, cause mechanism excessively
Complexity restricts load ratio bridging switch economy.
Utility model content
The purpose of this utility model is to provide a kind of spring energy-storage quick release mechanisms of double guide rails.The utility model knot
Structure design is simple, and compact, occupy-place is small, greatly reduces the required precision of manufacture, assembly, easy to implement, and the utility model is also
With high reliablity, the advantages of long service life.
The technical solution of the utility model includes: spring energy-storage quick release mechanism, including bottom plate, across bottom plate setting
Transmission shaft, and the machine core being arranged on bottom plate；The machine core includes the lower slide box for the upper slide box sum being slidably matched, the upper cunning
