Abstract
The utility model relates to a double load switch operation device, which is composed of a left crank arm, a right crank arm and a middle operating mechanism, wherein, one end of the left crank arm is connected with a first load switch operating lever. One end of the right crank arm is connected with a second load switch operating lever; the middle operating mechanism is composed of a pivoted arm; the center of the pivoted arm is connected with a hand (an electric) operating lever. The utility model is characterized in that the other end of the left crank arm is hinged with one end of the pivoted arm by a hinged left draw rod, and the other end of the right crank arm hinges with the other end of the pivoted arm by a hinged right draw rod. The operations of the left and the right crank arms of the utility model are respectively driven by that the pivoted arm drives the left and the right draw rods, wherein, when one load switch operates, the other load switch can not change from opening (closing) state to closing (opening) state, and thus, the closing and opening operations of the two load switches are realized. The closing and opening operations is realized by two sets of simple connecting rod mechanisms of the double load switch operation device; thereby, the utility model has the advantages of simple and compact structure and reliable mutual locking performance.
Description
Technical field
The utility model belongs in a kind of panel switches cabinet the operating mechanism of two on-load switches in deciliter incoming line cabinet, is a kind of pair of on-load switch operating means specifically.
Background technology
The conventional at present two inlet wire on-load switch operating mechanisms that use, the mode of operation of employing is for to carry out independent operation to realize the divide-shut brake of two on-load switches to two mechanisms.But for the interlocking capability that reaches two operating mechanisms (after an on-load switch closes a floodgate, another on-load switch can not close a floodgate again, promptly two on-load switches can not be located into the while "on" position) requirement, must increase a series of mechanical interlockss therebetween, and the interlock design is comparatively complicated, also there is certain limitation, thereby makes the reliability of interlocking cannot say for sure to demonstrate,prove.
Summary of the invention
But but the purpose of this utility model provides a kind of simple and reliable, both manual operations, also electric operating, and possesses two on-load switch operating means of reliable interlocking performance, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of the arm of turning left, turn right arm and intermediary operation mechanism, arm one end of wherein turning left links to each other with the first on-load switch action bars, turn right arm one end and the second on-load switch action bars joins, intermediary operation mechanism is made of a pivoted arm, the center of pivoted arm is connected with manual (electronic) action bars, be characterized in: the other end of the arm of turning left is hinged by an end of a hinged left lever and pivoted arm, and the other end of the arm of turning right is hinged by the other end of a hinged right pull bar and pivoted arm.
Because the action of the left and right connecting lever of the utility model drives left and right pull bar by pivoted arm in the intermediary operation mechanism respectively and drives, and when wherein an on-load switch moves, another on-load switch can not realize that promptly two mechanisms seem independent, deciliter action of tight association actually by closing (branch) lock state to dividing (closing) state.This point relies on the simple linkage of two covers in the device to be achieved.Since to make a left side (right side) mechanism by minute (closing) lock state to closing (branch) lock state, connecting lever must rotate 80 degree, when a backward stick action, another pull bar drives corresponding connecting lever rotation with the pivoted arm action, when connecting lever rotates a low-angle, the pull bar corresponding with it arrives the position, dead point of himself, when continuing action again, returns until required mechanism along former road again and closes (branch) lock.Very natural, formed a kind of self locking between two mechanisms, thereby made entire mechanism action seem simple, compactness and interlocking dependable performance.
Description of drawings
Fig. 1 is that the utility model is at two gate-dividing state structural representations.
Fig. 2 is that the utility model is at left "on" position structural representation.
Fig. 3 is that the utility model is at right "on" position structural representation.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model drives 7,8 actions of the first and second on-load switch action bars respectively by left and right sides pull bar 4,5, to realize the divide-shut brake of two on-load switches in manually (electronic) action bars 6 operation pivoted arms 1 rotation.When two on-load switches are in gate-dividing state simultaneously (Fig. 1), to operate pivoted arm 1 counterclockwise and rotate, left lever 4 pulling connecting levers 2 drive the first on-load switch action bars 7, and first on-load switch is closed a floodgate.This moment, second on-load switch was failure to actuate, and promptly still was in gate-dividing state.Operate pivoted arm 1 more clockwise and rotate, left lever 4 promotes connecting lever 2, drives the first on-load switch action bars 7, makes the first on-load switch separating brake.Continue operation pivoted arm 1 rotation clockwise, 3 actions of right pull bar 5 pulling connecting levers drive the second on-load switch action bars 8, and second on-load switch is closed a floodgate.This moment, first on-load switch was failure to actuate equally, promptly still was in gate-dividing state.Otherwise the operation of another mistake hour hands, the second on-load switch separating brake.So far, two on-load switches all are in gate-dividing state again, have promptly finished branch, the making process of two inlet wire on-load switches.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
