Description
Technical field
The present invention relates to a kind of electric/manual divide-shut brake conversion equipment of changing knob and having this conversion knob, belong to state exchange control field.
Background technology
According to the needs of operation, in the use of circuit breaker, often need realize the conversion operations between electronic divide-shut brake and the manual divide-shut brake, thus, the conversion equipment that is applied to the electric/manual divide-shut brake of circuit breaker is used and is given birth to.
Chinese patent document CN201946538U discloses a kind of RCCB electric and hand divide-shut brake push button transducer; As shown in Figure 1; Said transducer comprises a transducer seat 5; Said transducer seat 5 is near movable plate 6, and said transducer seat 5 is provided with a sliding tray vertically, and installing one in the said sliding tray can be along its carriage release lever that moves around 4; The upper end of said carriage release lever 4 is stretched out said sliding tray and is connected a button and spring 3 of socket, and the lower end of said carriage release lever 4 is stretched out said sliding tray and is fixedly connected a chock with inclined-plane.When the electronic divide-shut brake of needs, press said button, said chock moves down along said sliding tray under the drive of carriage release lever 4; Its inclined-plane stretches out said sliding tray; And be resisted against and give 6 one active forces to the right of said movable plate on the movable plate 6 of circuit breaker, thereby make said movable plate 6 move right, make the extension spring 7 of circuit breaker be stretched; And make and be installed in gears 10 on the motor shaft towards tooth bar 11 motions through driving motor 8; And with 11 engagements of said tooth bar, and then realize the control of motor to the handle opening and closing movement, realize electronic folding lock state; When the manual divide-shut brake of needs, press button once more, under the elastic force of spring 3 drives; Said button is upspring, and moves upward along sliding tray thereby drive carriage release lever 4, when the upper surface 90 of said chock is withstood by the upper wall 91 of said sliding tray and can not continue to move upward the time; The inclined-plane of said chock is positioned at said sliding tray fully; And then making said inclined-plane break away from said movable plate 6, said movable plate 6 to left movement, makes gear 10 separate with tooth bar 11 under the drive of extension spring 7; At this moment; Can't control circuit breaker handle through the motion drive tooth 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, be manual opening and closing state this moment.
Above-mentioned transducer is realized the conversion between the electric/manual through pushing said button.In some cases; Other people need judge highly that with respect to exposing of said breaker cover 30 upper surfaces it still is manual opening and closing state that said circuit breaker is in electronic opening and closing state according to said button; When expose highly hour (be said button be in the state that be pressed) of said button with respect to said breaker cover 30, circuit breaker is in electronic opening and closing state; When said button is highly big with respect to exposing of breaker cover 30; (being that said button is in the state of being upspring), circuit breaker is in manual opening and closing state, for some personnel that are lacking in experience; Often can't hold the above-mentioned height that exposes; Thereby can't judge accurately that it still is electronic opening and closing state that said circuit breaker is in manual opening and closing state, therefore, above-mentioned transducer is indicative relatively poor.
In order to overcome the problem of indicative difference, people attempt to substitute disclosed button in the above-mentioned document with the knob with sign.Disclosed indication knob in the prior art generally all is to make the corresponding a certain sign of said knob through rotary knob, thereby makes indication clear and definite.For example, Chinese patent document CN201600611U discloses a kind of indication knob of automobile controller, sees Figure 13; Comprise and be positioned at the positive designation card A of housing; With the guiding driving member of indication knob B coupling, the back side of said housing is provided with the boss with said guiding driving member coupling, the even some shrinkage pools that distribute in the surface of said boss; The center cylindrical hole at the intermediate cylindrical C of said guiding driving member and the said indication knob B back side is tightly pegged graft; Said intermediate cylindrical C both sides are respectively equipped with a hollow cylinder, are provided with spring and steel ball in the said hollow cylinder, and said steel ball is corresponding with the shrinkage pool of said boss surface; There is a concane gap at the front edge place of said indication knob B, the sign on the corresponding said designation card A of said concane gap.During use,, can make that the positive concane gap of said indication knob B is corresponding with the sign on the said designation card A through rotating said indication knob B; In the process of rotation, the intermediate cylindrical C of said guiding driving member is motionless, and has only the said relatively intermediate cylindrical C of said indication rotation B to rotate; The indication principle of most of indication knob of the prior art all with the document in disclosed indication principle identical, at this moment, it is found that; Be difficult to disclosed indication knob in the document is applied in the existing RCCB electric/manual divide-shut brake push button transducer, because, if just simply replace button with above-mentioned indication knob; In the process of the said indication knob of rotation, said indication knob will rotate by said relatively carriage release lever so, and said carriage release lever is motionless all the time; But, for above-mentioned transducer, if in the process of the said indication knob of rotation; Said carriage release lever does not move; Just can not make the inclined-plane of said chock be electronic and manually between conversion transformation power is provided, thereby can not realize electronic and manually between conversion, and then make transducer lose efficacy; Therefore, will indicate knob to be applied in simply and can not solve the problem that has the indicative difference of transducer now in the existing push button transducer.
