Abstract
The utility model relates to a spatial linkage transmission device of a spring operation mechanism. The linkage transmission of the device is a linkage formed by using a limit connection rod, a separation brake pull rod, a middle connection rod and a driving pull rod to drive other components. The main points of the design includes that transverse transmission of the linkage transmission is changed at a 90-degree position and vertical transmission is performed when transmitted to a breaker main shaft. The connection rod and a connection pin is connected with an output crank arm and a universal joint bearing is assembled on a main crank arm of the breaker main shaft to directly drive the breaker main shaft to rotate, i.e. the transverse rotation of the main shaft drives vertical rotation of the breaker. The spatial linkage transmission device of the spring operation mechanism drives the breaker main shaft to rotate by means of changing directions of forces through the universal joint bearing, decreases quantity of elements and energy loss of corresponding transmission processes, achieves comparatively high transmission efficiency and is applicable to electricity delivery of electric fences and matching of power distribution devices.
