The accompanying drawing explanation
Fig. 1 is front view of the present utility model
Fig. 2 is right side view of the present utility model
Wherein, in 1-divide-shut brake direction board, 2-counter, 3-direction board universal driving shaft, the upper connecting rod of 4-, 5-minor axis, 6-minor axis connecting rod, 7-divide-shut brake main shaft, 8-lower link, 9-, connecting rod, 10-direction board connecting rod, 11-touch spring.
Embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, a kind of vacuum circuit-breaker divide-shut brake direction board link gear described in the utility model, comprise divide-shut brake main shaft 7, direction board universal driving shaft 3 and be installed on the divide-shut brake direction board 1 on direction board universal driving shaft 3, these are all modes of the direction board link gear that uses in the prior art.Wherein the mounting means between direction board universal driving shaft 3 and divide-shut brake direction board 1 is the mounting means used in prior art, be about to divide-shut brake direction board 1 and be fixed on the athwartship plane of direction board universal driving shaft 3, like this along with the rotation of direction board universal driving shaft 3 just can be carried out the conversion between " 0 " and " 1 " to divide-shut brake direction board 1.
Link gear comprises lower link 8, minor axis connecting rod 6, minor axis 5, upper connecting rod 4 and middle connecting rod 9, and these are all drive disk assemblies of link gear.Described minor axis 5 is fixedly installed on divide-shut brake main shaft 7 by minor axis connecting rod 6, but do not affect the rotation of divide-shut brake main shaft 7, what minor axis connecting rod 6 mainly played is exactly that minor axis 5 is carried out to the fixing effect in space, can certainly not use minor axis connecting rod 6, as long as minor axis 5 is fixed in addition, play fixing effect on other fixture just passable.As shown in Figure 2, on middle connecting rod 9 fixed installations and minor axis 5, minor axis 5 provides the space fixation for middle connecting rod 9.Lower link 8 tops are connected with middle connecting rod 9 pins, if equally other connected mode also can to play fixation just passable.Lower link 8 bottoms and 7 engagements of divide-shut brake main shaft, the mode of engagement can adopt any mode in prior art, when divide-shut brake main shaft 7 rotates like this, can impel lower link 8 to carry out upper and lower slip.Upper connecting rod 4 tops are fixedly connected with direction board connecting rod 10 rear ends, and upper connecting rod 4 bottoms are fixedly installed in middle connecting rod 9 middle parts, and these fixed forms all can adopt the various forms of modes that are fixedly connected with, riveted joint, pin connection etc.Described direction board universal driving shaft 3 is fixedly installed in direction board connecting rod 10 front ends, and direction board connecting rod 10 horizontal vertical are installed on direction board universal driving shaft 3 middle parts, by the axial rotation that can drive direction board universal driving shaft 3 that swings up and down of direction board connecting rod 10.
In order to play the needs of divide-shut brake time counting number, can install counter 2 additional, described counter 2 is fixedly installed in divide-shut brake direction board 1 below, can be directly and divide-shut brake direction board 1 be installed together, also can be arranged on suitable position, below by other fixtures.Divide-shut brake direction board 1 carries out switching toggle with counter 2 by touching spring 11, and the mode of stirring is that the mode of using in prior art gets final product.While namely counting, by touching the calculating beginning of spring 11 hit counters 2, tap once and count.
During actual the use, when needs carry out breaking-closing operating, divide-shut brake main shaft 7 carries out axial rotation, drive lower link 8 and carried out sliding up and down of vertical direction, because the rear portion of middle connecting rod 9 is fixed on minor axis 5, so the middle connecting rod 9 that slided up and down and driven of lower link 8 carries out sliding up and down of vertical direction.The vertical slip up and down of middle connecting rod 9 has just driven the sliding up and down of vertical direction of the upper connecting rod 4 that is fixed on middle connecting rod 9 middle parts.Equally, the vertical direction of upper connecting rod 4 slides up and down sliding up and down of the vertical direction that driven direction board connecting rod 10.The motion of the vertical direction of direction board connecting rod 10 has driven the axial motion of direction board universal driving shaft, thereby drives " O " of divide-shut brake direction board 1 and stirring of " 1 " two kinds of direction boards.When stirring, touch spring 11 and also carry out in real time the operation of hit counter count button, counter 2 is counted by the divide-shut brake direction board.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
