The load switch is characterized in that the lower ends of the energy storage spring side plates are hinged with the drive shaft turn arm, a guiding groove is arranged on the upper ends of the energy storage spring side plates, an energy storage guide pin bushing is arranged in the guiding groove, a driving frame connecting rod of the link mechanism is hinged with the connecting latch fastener turn arm, the terminal end is connected with an energy storage guide pin from a driven frame connecting rod, and the energy storage guide pin is pressed on the upper end of an upper spring holder of the energy storage spring. The load switch can guarantee the action stability of the energy storage spring side plates, can guarantee the positioning precision and stability of switch dividing and connecting, and does not need to arrange a step on a main shaft jacket furthermore, thereby lowering the manufacture cost of the main shaft jacket.
Description
Technical field
The utility model relates to a kind of on-load switch, particularly a kind of energy storage device of on-load switch.
Background technology
The energy storage device of on-load switch is in order to make branch, closing speed not be subjected to the influence of operator's operating physical force size, in the energy storage device of present on-load switch (as shown in Figure 1, 2), energy storage pilot pin 10 be provided in a side of power transmission shaft connecting lever 7 on, and guide groove 21 is arranged on the downside of energy-stored spring side plate 2, when driving, main shaft 8 connects 6 rotations of snap close connecting lever, connect snap close connecting lever 6 and drive energy-stored spring side plate 2 by linkage 3 again and move down, thereby come compressed energy-storage spring 4 along energy storage pilot pin 10.And energy-stored spring side plate 2 moves down just, be easy to generate the phenomenon that bumps against with spindle jacket 9, and for avoiding energy-stored spring side plate 2 and spindle jacket 9 collisions as much as possible, be that the position with respect to energy-stored spring side plate 2 with spindle jacket 9 is set as the diameter that step promptly reduces spindle jacket 9 these places at present, even but be provided with like this, in case installation accuracy is not controlled well, energy-stored spring side plate 2 and spindle jacket 9 case of collision still can appear, in addition, the energy storage device of this structure, the diameter of its energy storage pilot pin 10 is restricted and (is generally
8mm), can not do enough greatly, because if energy storage pilot pin 10 enlarged diameter, under the prerequisite that guarantees energy-stored spring 4 decrements, the length of the guide groove 21 of energy-stored spring side plate 2 also just extends, width is also widened, and the overall length of energy-stored spring side plate 2 also will extend, and may collide spindle jacket 9 so especially; And so little diameter (
Strength and stiffness 8mm) are not enough, can occur the situation of energy storage connecting plate instability in operating process, influence switch divide-shut brake positioning accuracy and reliability.
Summary of the invention
The purpose of this utility model is the deficiency that solves the energy storage device of above-mentioned on-load switch, and the energy storage device of the more reliable and more stable on-load switch of a kind of operation is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of energy storage device of on-load switch, include a power transmission shaft connecting lever, one connects the snap close connecting lever, one linkage, two energy-stored spring side plates, energy-stored spring and the spring base of device in two energy-stored spring side plates, it is characterized in that: the lower end of described energy-stored spring side plate is hinged on the power transmission shaft connecting lever, the upper end of energy-stored spring side plate is provided with guide groove, the energy storage guide pin bushing is located in this guide groove, the active side link of described linkage is with to be connected the snap close connecting lever hinged, and terminal driven side link is socketed on the energy storage pilot pin, and the energy storage pilot pin is pressed on the upper end of the upper spring seat of energy-stored spring.
Further, the diameter of described energy storage pilot pin is
12mm.
The beneficial effects of the utility model are: because guide groove is arranged on the upper end of energy-stored spring side plate, therefore in the stored energy operation process, terminal driven side link is directly to drive the guide groove slippage of energy storage pilot pin along the energy-stored spring side plate, and the energy-stored spring side plate itself does not have slippage, therefore just do not have that to collide spindle jacket possible yet, the diameter of energy storage pilot pin also can be accomplished enough greatly to guarantee its intensity and rigidity, guarantee the stationarity of energy-stored spring side plate action, switch divide-shut brake positioning accuracy and reliability have been guaranteed, in addition, also just no longer need on spindle jacket, establish step, thereby also reduce the processing cost of spindle jacket.

Embodiment
Now in conjunction with the accompanying drawings the utility model execution mode is further described:
As Fig. 3, shown in Figure 4, the embodiment of the energy storage device of a kind of on-load switch of the utility model, include a power transmission shaft connecting lever 7, one connects snap close connecting lever 6, one linkage 3 (four-bar mechanism), two energy-stored spring side plates 2, energy-stored spring 4 and the spring base 1 of device in two energy-stored spring side plates 2,5, the lower end of described energy-stored spring side plate 2 is hinged on the power transmission shaft connecting lever 7, the upper end of energy-stored spring side plate 2 is provided with guide groove 21, energy storage pilot pin 10 is sheathed in this guide groove 21, the active side link 31 of described linkage 3 is with to be connected snap close connecting lever 5 hinged, terminal driven side link 32 is socketed on the energy storage pilot pin 10, and energy storage pilot pin 10 is pressed on the upper end of the upper spring seat 1 of energy-stored spring 4, and the diameter of described energy storage pilot pin 10 is
12mm.When carrying out stored energy operation, driven by main shaft 8 and to connect 6 rotations of snap close connecting levers, connect snap close connecting lever 6 and drive energy storage pilot pins 10 by linkage 3 and move down, energy storage pilot pin 10 moves down and then drives upper spring seat 1 and move down, by upper spring seat 1 compressed energy-storage spring 4.
Present embodiment is because guide groove 21 is arranged on the upper end of energy-stored spring side plate 2, therefore in the stored energy operation process, terminal driven side link 32 is directly to drive guide groove 2 slippages of energy storage pilot pin 10 along energy-stored spring side plate 2, and energy-stored spring side plate 2 itself does not have slippage, therefore also just do not have the possibility that collides spindle jacket 9, the diameter of energy storage pilot pin 10 also can be accomplished enough big (diameter
12mm) to guarantee its intensity and rigidity, guarantee the stationarity of energy-stored spring side plate 2 actions, guaranteed switch divide-shut brake positioning accuracy and reliability, in addition, also just no longer need on spindle jacket 9, establish step, thereby also reduce the processing cost of spindle jacket.
