Description
Technical field
The utility model relates to a kind of low-voltage distribution two-way power supply automatic conversion technology field, especially relates to the quick close/open machine of a kind of duplicate supply spring energy-storage.
Background technology
Traditional duplicate supply close/open machine adopts electromagnet mechanism or motor Direct driver, and adopt electromagnet mechanism to exist and impact greatly, the shortcomings such as the life-span is short, poor reliability, may close a floodgate when low voltage convert failed, burns electromagnet; It is slow to there is speed in motor Direct driver, and the contact arcing time is long, affects the contact life-span.
Chinese patent 201210504769.8, disclose a kind of duplicate supply divide-shut brake drive conversion equipment, comprise support, swing arm unit, for drive described swing arm unit to swing double electromagnet assembly, for realize mechanical interlocked eccentric lock locking mechanism and for realize divide-shut brake commutate commutation assembly; Support offers reversing groove, and swing arm unit bottom is hinged with travelling arm, and the end of travelling arm is slidably disposed in reversing groove; Commutation assembly comprises driven unit and swings the reversing plate being arranged on reversing groove side, and one end of reversing plate is connected with driven unit, and driven unit drives reversing plate to swing, and makes the other end of reversing plate by the commutation channel enclosed of reversing groove or opens.Its complex structure, and inconvenient operation.
Summary of the invention
The utility model mainly provides a kind of compact conformation reasonable, the easily manufactured quick close/open machine of a kind of duplicate supply spring energy-storage.
The utility model is mainly solved by following technical proposals for above-mentioned technical problem:
The quick close/open machine of a kind of duplicate supply spring energy-storage, comprise switch case, upper brace and lower brace, contact sliding tray is provided with in described switch case, fixed rotating shaft is provided with in the upper end of described switch case, lower fixed rotating shaft is provided with in the lower end of described switch case, the upper brace be connected that to rotate with upper fixed rotating shaft is provided with in described upper fixed rotating shaft, the lower brace be connected that to rotate with lower fixed rotating shaft is provided with in described lower fixed rotating shaft, described upper brace and lower brace are by movable rotation-shaft phase activity orientation, described movable rotation-shaft is located in contact sliding tray, the bottom of described movable rotation-shaft is provided with the connecting rod fixed with movable rotation-shaft, described lower brace overcoat has spring, between described spring and upper fixed rotating shaft, be respectively equipped with baffle plate between fixed rotating shaft and spring down.
As preferably, one end of described connecting rod is to switch case extension, and described connecting rod slides along contact sliding tray.
Be provided with contact slide block in contact slide block slot, contact slide block and movable rotation-shaft fix.
When connecting rod pushes away left, contact slide block moves in combined floodgate direction left, and spring carries out energy storage simultaneously, when movable rotation-shaft is moved to the left the line exceeded between upper fixed rotating shaft and lower fixed rotating shaft, energy released by spring, and movable rotation-shaft band moving contact slide block is moved to the left fast, realizes rapid closing.In like manner, quick acting switching-off is realized when connecting rod draws to the right.Adopt this mechanism two cover, duplicate supply conversion can be realized.This mechanism can manual operation, also can electric operating, achieves quick-make or disjunction, has nothing to do, greatly improve extinguish arcs ability with the speed of operator link, extends contact useful life.
Achieve quick-make and disjunction, have nothing to do, greatly improve extinguish arcs ability with the speed of operator link, extend contact useful life, can adopt this mechanism two cover, can realize duplicate supply conversion, this mechanism can manual operation, also can electric operating.
