The technical scheme that this utility model is taked, particularly as follows: a kind of oil cylinder synchronization structure being capable of precise synchronization control, including at least two oil cylinder, and is used for transmitting the connecting rod of pulling force；
Also include at least one directive wheel, at least one drag-line and guide wheel bracket；Connecting rod one end is fixing connects guide wheel bracket；
Directive wheel is rotationally connected and is installed on guide wheel bracket, and drag-line is across being wound on directive wheel, and drag-line two ends connect the piston rod of an oil cylinder respectively.
When application, drag-line will be located in two oil cylinders of directive wheel both sides and links into an integrated entity, when oil cylinder compression or force-extension, when both sides, there is difference in oil cylinder stroke, then can there is play or drive directive wheel to rotate in drag-line, thus realizing the balance of power so that both sides stroke is complementary, namely reaches the purpose of oil cylinder Synchronization Control.
As a kind of embodiment, in this utility model, oil cylinder and connecting rod quantity are all 2, and oil cylinder and connecting rod lay respectively at the both sides of directive wheel.Described both sides can be upper and lower both sides or the left and right sides, and the transmission can realize connecting stick force act as benchmark.
