Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, on earthed switch operation connecting lever, design idle stroke structure, the mechanical wounding that may cause can overcome the earthed switch divide-shut brake with spring energy-storage system time, it is simple and practical, has increased the security performance of product.
Technical solution adopted in the utility model is:
A kind of operation crank arm structure of earthed switch, comprise the connecting lever 1 that is enclosed within main shaft 3, the end face that it is characterized in that connecting lever 1 is provided with step surface 11, form outstanding upper sector 12 and lower sector 13, on main shaft 3, be also fixed with axle sleeve 2, connecting lever 1 is provided with step 21 with the end face of corresponding axle sleeve 2, forms outstanding upper surface 22 and lower surface 23, the end face of the end face of axle sleeve 2 and connecting lever 1 is interlocked, and between the step surface 11 of the end face of connecting lever 1 and the step 21 of axle sleeve 2 end faces, is provided with idle stroke 4.
Use procedure is as follows: in the time that operational grounding switch is joined operating mechanism divide-shut brake, operating mechanism drives the action of earthed switch connecting lever by connecting rod, when connecting lever is covered room between axle sleeve (idle stroke), the action of drive main shaft, spring abrupt release energy behind dead point is grounded the quick divide-shut brake of cutter, main shaft is quick rotation in the time that spring releases energy, owing to having idle stroke between axle sleeve and connecting lever, so can not drive connecting lever, thereby while avoiding spring abrupt release energy, operator be damaged.
As preferably, the fan-shaped angle that the step surface 11 of above-mentioned connecting lever 1 forms outstanding upper sector 12 is 165 degree, and the fan-shaped angle that the step 21 of above-mentioned axle sleeve 2 end faces forms outstanding upper surface 22 is 165 degree.The end face of the end face of this technical scheme axle sleeve 2 and connecting lever 1 is interlocked, and the angle of the idle stroke 4 between the step surface 11 of the end face of connecting lever 1 and the step 21 of axle sleeve 2 end faces is 30 degree.
The utility model increases axle sleeve and a connecting lever with the level with step design and forms the room of, connecting lever drives the angular interval of rotating in main shaft, can utilize with the connecting lever of idle stroke and realize the operation of safety open combined floodgate, the spring resistance earthed switch that main shaft overcomes stage clip assembling closes a floodgate, and main shaft forwards position to, and connecting lever is covered and be provided with angular interval between axle sleeve, there is individual bumper angle, form idle stroke, operating grip also just can not be bound on hand, prevents from hindering the generation of hand accident.
The beneficial effects of the utility model are: the utility model has increased axle sleeve, and axle sleeve and connecting lever form room by step, between connecting lever and axle sleeve, are provided with bumper angle, and it is simple and practical, and security performance is high, have higher use promotional value.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
