Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, 2, 3, this isolation indicating structure that is used for breaker of plastic casing comprises cover 1, actuator 5, indication piece 2, spring 3 and baffle plate 4, the cover that cover 1 is breaker of plastic casing, baffle plate 4 is connected with cover 1, and indication piece 2, spring 3 are between baffle plate 4 and cover 1.The driving lever that is provided with an arc 24 of actuator 5 and two snap fits 31 (as shown in Figure 6), two snap fits 31 are stuck on the axle 7 of contact of breaker 6, and driving lever 24 is relative with indication piece 2.
As shown in Fig. 3,7,8, indication piece 2 comprises a trapezoid boss 18 and a push rod 32, trapezoid boss 18 is connected with push rod 32, push rod 32 is provided with a Pointing sign board 33, Pointing sign board 33 is provided with the colour code of two kinds of different colors, be respectively red mark 15 and blue mark 16, the downside of push rod 32 forms arc surface 17.Trapezoid boss is provided with an inclined-plane 19, and inclined-plane 19 is relative with driving lever 24, and the free end 26 of push rod 32 is connected with spring 3.
As shown in Fig. 3,4,5,9, baffle plate 4 is connected with the inner surface of cover 1, and baffle plate 4 is provided with two circular holes 21,22, and cover 1 is provided with 13,14, two boss 13,14 of two boss and is inserted in that two circular holes 21,22 are interior links together baffle plate 4 and cover 1.Between baffle plate 4 and cover 1, form the first holding tank 9 and the second holding tank 10, the first holding tanks 9 are greater than the second holding tank 10, the position that is also provided with observation window 8, the first holding tanks 9 on cover 1 is corresponding with the position of observation window 8.
What the push rod 32 of indication piece 2 slided penetrates in the first holding tank 9 and the second holding tank 10, Pointing sign board 33 in the first holding tank 9 and be positioned at observation window 8 below, spring 3 is positioned at the second holding tank 10.Baffle plate 4 is provided with one and slides arc groove 23, and push rod 32 is positioned at this arc groove 23, and the arc surface 17 of the downside of push rod 32 matches with arc groove 23.Adopt this structure, baffle plate 4 can form effectively and support indication piece 2, and the slip of indication piece 2 in arc groove 23 also can be more smooth, steady.
It is relative with a vertical plane 20 on trapezoid boss 18 with the second limited step 12, the first limited steps 11 that cover 1 is provided with the first limited step 11, and this vertical plane 20 and inclined-plane 19 are two sides relative on trapezoid boss 18.The second limited step 12 is relative with a side 27 of Pointing sign board 33.
As Fig. 1, shown in 2, this isolation indicating structure in use, in the time that breaker of plastic casing is transformed into off-state by closure state, the axle 7 of contact 6 is rotated counterclockwise, actuator 5 rotates together with axle 7, make driving lever 24 on actuator 5 upwards and to the right both direction move, make the driving lever 24 on actuator 5 withstand the inclined-plane 19 on indication piece 2, indication piece 2 overcomes the elastic force of spring 3 to right translation, after the vertical plane 20 of indication piece 2 upper trapezoid boss 18 and the first limited step 11 of cover 1 contact, indication piece 2 stops mobile, now the blueness mark 16 on the Pointing sign board 33 of indication piece 2 is just in time positioned at observation window 8 belows, observation window 8 shows blue.
As shown in figure 10, when breaker of plastic casing is during in state of section by disconnecting to closure conversion, the axle 7 of contact 6 clockwise rotates along rotating shaft, actuator 5 rotates together with axle 7, make driving lever 24 on actuator 5 left and downwards both direction move, indication piece 2 under the effect of the elastic force of spring 3 to left.Now the redness mark 15 on the Pointing sign board 33 of indication piece 2, blue mark 16 each some be positioned at observation window 8 belows, red, two kinds of colors of indigo plant that observation window 8 shows.
As shown in figure 11, when in the time that breaker of plastic casing is transformed into closure state, the axle 7 of contact 6 continues to clockwise rotate along rotating shaft, actuator 5 rotates together with axle 7, driving lever 24 on actuator 5 is moved down with indication piece 2 to depart from, indication piece 2 under the effect of the elastic force of spring 3 to continue left, until the side 27 on Pointing sign board 33 stops after contacting with the second limited step 12, now the redness mark 15 on the Pointing sign board 33 of indication piece 2 is just in time positioned at observation window 8 belows, and observation window 8 shows red.
The above-mentioned isolation indicating structure that this is used for breaker of plastic casing can drive indication piece 2 to move around according to the action of contact 6; and then the demonstration of realization red blue two kinds of different colours on observation window 8; look into by sight the residing state of this contact of breaker of judgement that color relation that observation window 8 shows can be correct like this; make the operators such as line maintenance correctly judge that whether controlled circuit is really in a safe condition, protection operator's personal safety.
The isolation indicating structure for the breaker of plastic casing above embodiment of the present invention being provided is described in detail; for one of ordinary skill in the art; according to the thought of the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
