Description
Technical field
The utility model relates to electric power system field of switch equipment, specifically a kind of switchgear mechanism connecting lever linkage.
Background technology
Auxiliary switch is adopted to output signal in high voltage switchgear, the contact of auxiliary switch is generally rotated versions, and the output form of switchgear operating mechanism has rotation and direct acting two kinds of forms mutually, owing to limitting by mechanism position, be connected to auxiliary switch and rotate and direct acting two kinds exports and is connected not when same plane, three-dimensional connection often difficulty, existing mechanism steadily connects for realizing, devise several connected mode, but it is all very complicated, a kind of conventional direct acting as shown in Figure 1+rotate+rotate three positional structures, first rectilinear motion is done by screw along leading screw, screw drives shift fork to rotate simultaneously, shift fork is connected with a bevel gear set away from one end of screw, this bevel gear set drives auxiliary switch to rotate, auxiliary switch is outputed signal, this structure is comparatively complicated, and bevel gear and shift fork requirement on machining accuracy higher, considerably increase production and processing cost.
Utility model content
The purpose of this utility model is to provide a kind of switchgear connecting lever linkage, drives auxiliary switch to rotate by two connecting levers and a connecting rod, simple and practical, greatly reduces production cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of switchgear connecting lever linkage, comprise output toggle arm, rotating shaft, connecting rod and auxiliary switch connecting lever, wherein output toggle arm and auxiliary switch connecting lever are hingedly mounted on connecting rod two ends respectively by rotating shaft, output toggle arm is arranged on the output shaft of operating mechanism away from one end of described connecting rod, and auxiliary switch connecting lever is connected with auxiliary switch.
Described rotating shaft is connected with described connecting rod by pivot pin, and described rotating shaft is arranged on output toggle arm and auxiliary switch connecting lever respectively by spring collar.
Advantage of the present utility model and good effect are:
1, the utility model drives auxiliary switch to rotate by two connecting levers and connecting rod, achieves the three-dimensional motion of rotation+direct acting+rotation, simple and practical, and the utility model in transmission process, each parts can Double-directional rotary, do not produce catching phenomenon.
2, the utility model part is small, and therefore whole volume can do very little, can save mechanism space.
3, the utility model is easy to processing and manufacturing, saves material, greatly reduces production cost.

Wherein, 1 is output toggle arm, and 2 is rotating shaft, and 3 is pivot pin, and 4 is connecting rod, and 5 is spring collar, and 6 is output shaft, and 7 is auxiliary switch, and 8 is auxiliary switch connecting lever.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figures 2-3, the utility model comprises output toggle arm 1, rotating shaft 2, pivot pin 3, connecting rod 4, spring collar 5 and auxiliary switch connecting lever 8, wherein output toggle arm 1 and auxiliary switch connecting lever 8 are hingedly mounted on connecting rod 4 two ends respectively by rotating shaft 2, two rotating shafts 2 are connected with described connecting rod 4 respectively by pivot pin 3, and are arranged on output toggle arm 1 and auxiliary switch connecting lever 8 respectively by a spring collar 5.
As shown in Figure 4, output toggle arm 1 is arranged on the output shaft 6 of operating mechanism away from one end of described connecting rod 4, auxiliary switch connecting lever 8 is connected with auxiliary switch 7, output toggle arm 1 rotates with output shaft 6, therefore output toggle arm 1 exports is a camber line, and drivening rod 4 lifting and swinging, described connecting rod 4 drives auxiliary switch connecting lever 8 to rotate, and auxiliary switch 7 is rotated and sends signal.
Operation principle of the present utility model is:
The output shaft 6 of operating mechanism rotarily drives output toggle arm 1 and rotates, and drive connecting rod 4 lifting and swinging be attached thereto, described connecting rod 4 drives auxiliary switch connecting lever 8 to rotate, and then drive auxiliary switch 7 rotation to send signal by described auxiliary switch connecting lever 8, the utility model achieves the three-dimensional motion of rotation+direct acting+rotation, simple and practical, and the utility model can Double-directional rotary in transmission process, does not produce catching phenomenon.
