Description
Technical field
The present invention relates to a kind of electric/manual switching off/on device of changing knob and thering is this conversion knob, belong to state conversion and control field.
Background technology
According to the needs of operation, in the use procedure of circuit breaker, often need to realize electronic divide-shut brake and the manual conversion operations between divide-shut brake, thus, be applied to circuit breaker electric/manual divide-shut brake converter application and give birth to.
Chinese patent literature CN201946538U discloses a kind of residual current circuit breaker electric and hand divide-shut brake push button transducer, as shown in Figure 1, described transducer comprises a transducer seat 5, described transducer seat 5 is near movable plate 6, described transducer seat 5 arranges a sliding tray vertically, a carriage release lever that can move around along it 4 is installed in described sliding tray, the upper end of described carriage release lever 4 is stretched out described sliding tray and is connected a button and be socketed a spring 3, and the lower end of described carriage release lever 4 is stretched out described sliding tray and is fixedly connected with a bevelled chock of tool.When the electronic divide-shut brake of needs, press described button, described chock moves down along described sliding tray under the drive of carriage release lever 4, its inclined-plane stretches out described sliding tray, and be resisted against on the movable plate 6 of circuit breaker to 6 one of described movable plates active force to the right, thereby described movable plate 6 is moved right, the extension spring 7 of circuit breaker is stretched, and the gear 10 that makes to be arranged on motor shaft by drive motor 8 moves towards tooth bar 11, and mesh with described tooth bar 11, and then realize the control of motor to handle opening and closing movement, realize driven opening combined floodgate state, when the manual divide-shut brake of needs, again press button, under the elastic force of spring 3 drives, described button is upspring, thereby drive carriage release lever 4 to move upward along sliding tray, when the upper surface 90 of described chock is withstood by the upper wall 91 of described sliding tray and can not continue to move upward, the inclined-plane of described chock is positioned at described sliding tray completely, and then make described inclined-plane depart from described movable plate 6, described movable plate 6 under the drive of extension spring 7 to left movement, make gear 10 separated with tooth bar 11, now, cannot control circuit breaker handle by the Sports band carry-over bar 11 of motor 8 and do separating brake or feed motion, can only rely on manually and could realize circuit breaker handle separating brake or feed motion, it is now manual opening and closing state.
Above-mentioned transducer is realized the conversion between electric/manual by pressing described button.In some cases, other people need to judge that with respect to the ride out of described breaker cover 30 upper surfaces described circuit breaker is in electronic opening and closing state or manual opening and closing state according to described button, when described button is with respect to the ride out of described breaker cover 30 hour (being the state of described button in being pressed), circuit breaker is in electronic opening and closing state; When described button is larger with respect to the ride out of breaker cover 30, (being the state of described button in being upspring), circuit breaker is in manual opening and closing state, the personnel that are lacking in experience for some, often cannot hold above-mentioned ride out, thereby cannot judge accurately that described circuit breaker is in manual opening and closing state or electronic opening and closing state, therefore, above-mentioned transducer is indicative poor.
In order to overcome the problem of indicative difference, people attempt to substitute disclosed button in above-mentioned document with the knob with sign.Disclosed indicating knob in prior art, is all generally to make the corresponding a certain sign of described knob by rotation knob, thereby makes indication clear and definite.For example, Chinese patent literature CN201600611U discloses a kind of indicating knob of automobile controller, see Figure 13, comprise the designation card A that is positioned at housing front, the guiding driving member mating with indicating knob B, the back side of described housing is provided with the boss mating with described guiding driving member, the surface uniform of described boss some shrinkage pools that distribute, the center cylindrical hole at the intermediate cylindrical C of described guiding driving member and the described indicating knob B back side is tightly pegged graft, described intermediate cylindrical C both sides are respectively equipped with a hollow cylinder, in described hollow cylinder, be provided with spring and steel ball, described steel ball is corresponding with the shrinkage pool of described boss surface, there is a concane gap at the front edge place of described indicating knob B, sign on the corresponding described designation card A of described concane gap.During use, by rotating described indicating knob B, can make the concane gap in described indicating knob B front corresponding with the sign on described designation card A, in the process of rotation, the intermediate cylindrical C of described guiding driving member is motionless, and only have described indication rotation B to rotate relative to described intermediate cylindrical C, the indication principle of most of indicating knob of the prior art is all identical with disclosed indication principle in the document, now, it is found that, be difficult to disclosed indicating knob in the document to be applied in existing residual current circuit breaker electric/manual divide-shut brake push button transducer, because, if just simply replace button with above-mentioned indicating knob, so in the process of the described indicating knob of rotation, described indicating knob will rotate relative to described carriage release lever, and described carriage release lever is motionless all the time, but, for above-mentioned transducer, if in the process of the described indicating knob of rotation, described carriage release lever does not move, the inclined-plane that just can not make described chock for electronic and manually between conversion transformation power is provided, thereby can not realize electronic and manually between conversion, and then transducer was lost efficacy, therefore, simply indicating knob is applied in to the problem that can not solve the indicative difference of existing transducer in existing push button transducer.
