Abstract
The utility model discloses a grounding switch operating crank arm, comprising a stopper (2) and a rotary arm (3), wherein the stopper (2) is cylindrical and is fastened on the rotation shaft (4) of a grounding switch, the end face of one side of the stopper (2) is provided with an protruding step, the step forms a proper angle, the rotary arm (3) is provided with a hole, the rotation shaft (4) of the grounding switch penetrates into the hole of the rotary arm (3), the end face of the rotary arm (3), contacting with the stopper (2) is provided with a concave step, and the concave step of the rotary arm (3) can contain the protruding step of the stopper (2) and also has surplus space. The rotary arm of the grounding switch operating crank arm does not rotate under other external forces except under the action of operators in the whole operation process, thereby avoiding accidentally injuring the operators.
Description
Technical field
The utility model belongs to electrical technology field, relates to a kind of earthed switch operation connecting lever.
Background technology
Earthed switch is a kind of equipment of artificial manufacturing ground connection, and its effect is the safety of staff when guaranteeing to overhaul power circuit.Earthed switch has energy-stored spring, can drive the earthed switch rapid closing.The precondition of energy-stored spring action is: the staff provides power by the rotation of earthed switch operation connecting lever, and the rotating shaft that this operation connecting lever drives earthed switch rotates to certain angle.Existing earthed switch such as JN4 series, its operation connecting lever directly is fastened in the rotating shaft of earthed switch, all the time with its synchronous rotary.The shortcoming of this operation connecting lever is: after the action of earthed switch energy-stored spring, the rotating shaft rotary speed of earthed switch is accelerated, and causes also Spin-up of this operation connecting lever, easily accidentally injures the staff.
Summary of the invention
The purpose of this utility model is that design is a kind of simple in structure, and can not accidentally injure staff's earthed switch operation connecting lever.
Technical solutions of the utility model are achieved in that a kind of earthed switch operation connecting lever, it is characterized in that, are comprised of stop and turning arm.Stop is cylindric, is fastened on the ground switch rotating shaft, and there is raised step the one side end face, and this step forms suitable angle; Turning arm is porose, is set on the ground switch rotating shaft, and its section that contacts with stop has recess step.The recess step of turning arm can contain the raised step of stop and remain suitable neutral.
When the earthed switch operation connecting lever that the utility model provides operates, the staff makes the turning arm rotation, the raised step of its recess step and stop interacts, stop also rotates, and stop drives the ground switch rotating shaft rotation to the appropriate location, the energy-stored spring action, energy-stored spring releases energy the ground switch rotating shaft rotary speed is accelerated, cause also Spin-up of stop, the stroke of the raised step of stop all in the recess step neutral of turning arm, can not rotate by the driven rotary arm at this moment.In whole process, the turning arm of earthed switch operation connecting lever is not subject to other external force and rotates except rotate because of staff's effect, so can not accidentally injure the staff.
Description of drawings
Fig. 1 is the structural representation of existing JN4 type earthed switch operation connecting lever;
Fig. 2 is the structural representation of an embodiment of the utility model earthed switch operation connecting lever;
Fig. 3 is the structural representation of the stop of earthed switch operation connecting lever embodiment illustrated in fig. 2;
Fig. 4 is the structural representation of the stop turning arm of earthed switch operation connecting lever embodiment illustrated in fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, earthed switch operation connecting lever 2, stop 3, turning arm 4, ground switch rotating shaft 5, energy-stored spring
Such as Fig. 2, Fig. 3, shown in Figure 4, the utility model earthed switch operation connecting lever is comprised of stop 2 and turning arm 3.Stop 2 is cylindric, is fastened on the ground switch rotating shaft 4, and there is raised step the one side end face, and this step forms suitable angle; Turning arm 3 is porose, is set on the ground switch rotating shaft 4, and it has recess step with the section that stop 2 contacts.The recess step of turning arm 3 can contain the raised step of stop 2 and remain suitable neutral.
During operation, the staff makes turning arm 3 rotations, and the raised step of its recess step and stop 2 interacts, and stop 2 also rotates; Stop 2 drives ground switch rotating shaft 4 rotations to the appropriate location, energy-stored spring 5 actions, energy-stored spring 5 releases energy ground switch rotating shaft 4 rotary speeies is accelerated, cause also Spin-up of stop 2, the stroke of the raised step of stop 2 all in the recess step neutral of turning arm 3, can not rotate by driven rotary arm 3 at this moment.In whole process, the turning arm 3 of earthed switch operation connecting lever is not subject to other external force and rotates except rotate because of staff's effect, so can not accidentally injure the staff.
