Small-size multi-way valve operating mechanism assembly

Abstract

The invention discloses a small-size multi-way valve operating mechanism assembly, relating to the technical field of mechanical transmission control; a maneuvering handle (1) is arranged at the upper end of a handle bar (2); a dust-proof rubber sheath (3) is sheathed at the lower part of the handle bar; the lower end of the dust-proof rubber sheath is sheathed and clamped at the upper part of a controller base (11); the lower end of the handle bar is connected with the upper face of a handle rock shaft (4) in the dust-proof rubber sheath; the upper ends of a sliding connecting rod A (5), a sliding connecting rod B (7) and a supporting connecting rod (13) are respectively a spherical structure; and the sliding connecting rod A, the sliding connecting rod B and the supporting connecting rod are respectively matched with two hole-shaped sliding chutes of the handle rock shaft in a sliding manner. The invention has flexible manipulation and single-rod dual-axis control function, can realize independent movement of each sliding rod according to actual requirements and can realize homodromous or reversed motion of the two sliding rods, thereby preventing accidents from occurring.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical transmission control, in particular to a small multi-way valve control mechanism assembly. 【Background technique】 [0002] Known multi-way valves are used in a wide range of fields. They are mainly used to control the flow direction of hydraulic oil. In use, there are single-lever control to achieve a single function, and there are also those that require two-way valves to achieve compound actions; such as skid steer loaders. Bucket boom control requires that when the boom is lifted or lowered while the bucket has to flip, etc., it is realized through the multi-way valve control mechanism to issue instructions; if it is two-lever control, the driver requires both hands Control, because it is controlled by both hands, it is impossible to control the direction or position of the vehicle. Moreover, most of the existing single-rod dual-axis multi-way valves use universal cross shafts for directi...

[0002] Known multi-way valves are used in a wide range of fields. They are mainly used to control the flow direction of hydraulic oil. In use, there are single-lever control to achieve a single function, and there are also those that require two-way valves to achieve compound actions; such as skid steer loaders. Bucket boom control requires that when the boom is lifted or lowered while the bucket has to flip, etc., it is realized through the multi-way valve control mechanism to issue instructions; if it is two-lever control, the driver requires both hands Control, because it is controlled by both hands, it is impossible to control the direction or position of the vehicle

Moreover, most of the existing single-rod dual-axis multi-way valves use universal cross shafts for direction conversion. The disadvantage of this structure is that it is too bulky and has no mid-position anti-misoperation locking function; It takes up too much space when used on the road, and at the same time requires the driver to lock the hydraulic control device after leaving the vehicle to prevent accidents
