Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic accessories, and more specifically, particularly relates to an oil distributor for a servo oil cylinder. Background Art

[0002] In the hydraulic system, a complete hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary elements and hydraulic oil, among which the servo cylinder is the actuator, the hydraulic oil pump is the power element, and the control element is the oil distributor and other components. The oil distributor plays the role of adjusting the direction of the hydraulic system's fluid flow circuit and switching the locking state. When in use, the multiple interfaces of the oil distributor are connected to the hydraulic circuit through flanges, and the internal passage direction of the oil distributor is adjusted by manually rotating the handle to achieve the reversing and locking effects of the hydraulic circuit.

[0003] However, as for the current traditional handle-controlled oil distributor, the oil distributor adjustment handle rotates to connect the oil distributor. If the control handle is hit by external force or accidentally touched by humans, the handle will rotate, causing incorrect control, which can easily cause confusion in the hydraulic system and cause unnecessary trouble.

It can be seen that the handle of the oil distributor in the present application has an automatic locking effect, which can avoid the rotation of the handle caused by external force factors and avoid accidental touch.

[0014] 2. The limit lock column in the present application is located at the bottom of the longitudinal groove of the collar under normal conditions. If the limit lock column is pushed upward, the push lock rod can be pushed inward as a whole through the action of the inclined push rod in the inclined state, so that the locking tooth and the handle locking tooth ring are disengaged. When the limit lock column enters the position of the limit outer groove, the limit lock column is positioned under the action of the groove body of the limit outer groove and the tightening effect of the reset top spring, so that the limit lock column continues to lock the push lock rod, so that the oil distributor handle remains in the released state, which is used to control the oil distributor of the hydraulic system that is more frequently used, so that the oil distributor has the switching between automatic locking and automatic locking release.
