Fig. 2 is the sectional view of the utility model direct-operated isolating switch "on" position.
Fig. 3 is the sectional view of the utility model direct-operated isolating switch gate-dividing state.
Specific embodiment
To make one of ordinary skill in the art be more clearly understood from the purpose of this utility model, technical scheme and excellent
Point, is further elaborated below in conjunction with drawings and Examples to the utility model.
As shown in figure 1, direct-operated isolating switch includes framework 10, three switch members 20 being fixed on framework 10 and sets
In the rotating shaft 30 on framework.Framework 10 is fixed on outside, for supporting switch part 20 and rotating shaft 30.
Each switch member 20 includes the first contact 21 for being arranged at bottom, the second contact 22 for being arranged at top, and
Through the first contact 21 and conducting rod moving up and down 23.First contact 21 and the longitudinally opposed setting of the second contact 22, it is conductive
A tooth bar 231 is longitudinally provided with the lateral surface of bar 23.To ensure good insulating properties, the first contact 21 can be by insulation and machine
Tool epoxide resin material of good performance or environmentally-friendly plastic material are poured into a mould integral with upper and lower inlet-outlet line.When conducting rod 23 is upward
When being moved to its end and being contacted with the second contact 22, switch member is closed a floodgate；Touched with second when conducting rod 23 is moved downward to its end
During first 22 separation, switch member separating brake.
As shown in figure 3, in the present embodiment, conducting rod 23 sets curved guiding surface 232 towards the end of the one end of the second contact 22,
The setting of curved guiding surface 232 is easy to conducting rod 23 to enter the second contact 22, reduces to be inserted between the second contact 22 and conducting rod 23 and rubs
Power is wiped, and reduces contact resistance, generated heat when reducing work, save electric energy.
Preferably, the second contact 22 is configurable to Mume flower contact.Mume flower contact is provided with beneficial to conducting rod 23 and
The steady contact of two contacts.
In the present embodiment, conducting rod 23 is tubular.The conducting rod of tubular is easy to movement, and can reduce conducting rod 12
Resistance during with the second contact.
Correspond in rotating shaft 30 at each conducting rod and be fixed with a gear 31, gear 31 is engaged with corresponding tooth bar 231,
