Abstract
A multi-way valve flexible shaft operating and adjusting mechanism for tractors and engineering machinery comprises an operating flexible shaft assembly, an adjusting nut, a sleeve, a flexible shaft bend, a press plate and a pressing nut. A U-shaped fork is arranged at the upper end of the operating flexible shaft assembly, outer screw threads are arranged at the lower end of the operating flexible shaft assembly, the adjusting nut is sleeved on the lower end of the operating flexible shaft assembly, the outer screw threads on the operating flexible shaft assembly is in threaded connection with inner screw threads at the front end of the sleeve, the front end of the sleeve is screwed on the operating flexible shaft assembly through the adjusting nut, a round flange at the rear end of the sleeve is pressed on a multi-way valve body through the press plate and locked through the pressing nut, the flexible shaft bend is fixedly connected at the lower end of the operating flexible shaft assembly, and the flexible shaft bend is arranged in a valve rod hole in hanging mode. The multi-way valve flexible shaft operating and adjusting mechanism for the tractors and the engineering machinery is simple in structure, small in size and convenient to adjust, a valve rod is located in a relative enclosed space, bump, abrasion and corrosion of the valve rod are avoided, and using requirements of the tractors and the engineering machinery are completely met.
Description
Technical field
The utility model belongs to tractor and engineering machinery field, relates to a kind of Multi-way valve soft-shaft for tractor and engineering machinery and handles and regulating mechanism.
Background technique
At present, on the tractor and engineering machinery of producing at home, the Multi-way valve soft-shaft operating mechanism that configures all adopts flexible axle control lever, realize stem movement by the lever conversion, this mechanism takes up space larger, and complete machine is arranged relatively difficulty, and the adjustment of flexible axle stroke is also inconvenient.Simultaneously, valve rod be exposed to outer easily cause valve rod collide with wearing and tearing and corrosion.In order to remedy this deficiency, be necessary to develop a kind of simple and reliable for structure, small volume, easy to adjust, the Multi-way valve soft-shaft of good seal performance is handled and regulating mechanism, to satisfy the usage requirement of tractor and engineering machinery.
The model utility content
The purpose of this utility model is to provide a kind of simple and reliable for structure, small volume, and is easy to adjust, and the Multi-way valve soft-shaft that is used for tractor and engineering machinery of good seal performance is handled and regulating mechanism, to satisfy its usage requirement.
The technical solution of the utility model is: the Multi-way valve soft-shaft that is used for tractor and engineering machinery is handled and regulating mechanism, comprising: operation flexible axle assembly, adjusting nut, sleeve, flexible axle elbow, pressing plate and gland nut.Operation flexible axle assembly upper end is provided with the U-shaped fork, the lower end is provided with outside thread and is set with adjusting nut, outside thread on the operation flexible axle assembly and the internal thread of barrel forward end are spirally connected, barrel forward end is tightened on the operation flexible axle assembly by adjusting nut, the circular flange of sleeve rear end is pressed on the multichannel valve body by pressing plate, and by nut check.
Operation flexible axle assembly lower end is connected with the flexible axle elbow, and the flexible axle elbow is articulated in the valve rod hole.
The utility model can reach following beneficial effect: because flexible axle connects with the hydraulic valve stem hole by elbow, flexible shaft jacket is connected with sleeve by screw thread, and sleeve is pressed on the hydraulic valve by pressing plate, just can realize the straight line motion of valve rod by operation flexible axle; When the flexible axle stroke need to be adjusted, only need to unclamp gland nut and adjusting nut, turnbarrel just can reach correct position locking gland nut and adjusting nut.This mechanism structure is simple, and small volume is easy to adjust, and simultaneously valve rod is in the relative closure space, has avoided that valve rod collides with, wearing and tearing and corrosion.
Description of drawings
Fig. 1 is that the utility model is used for the Multi-way valve soft-shaft manipulation of tractor and engineering machinery and the structural representation of regulating mechanism.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Shown in Fig. 1, the Multi-way valve soft-shaft that is used for tractor and engineering machinery is handled and regulating mechanism, mainly comprises: operation flexible axle assembly 1, adjusting nut 2, sleeve 3, flexible axle elbow 4, pressing plate 5 and gland nut 6; Operation flexible axle assembly 1 upper end is provided with the U-shaped fork, the lower end is provided with outside thread and is set with adjusting nut 2, the internal thread of the outside thread on the operation flexible axle assembly 1 and sleeve 3 front ends is spirally connected, sleeve 3 front ends are tightened on the operation flexible axle assembly 1 by adjusting nut 2, the circular flange of sleeve 3 rear ends is pressed on the multichannel valve body 7 by pressing plate 5, and by nut 6 lockings.Operation flexible axle assembly 1 lower end is connected with flexible axle elbow 4, and flexible axle elbow 4 is articulated in the valve rod hole 8.The size of flexible axle elbow 4 is less than sleeve 3 minor diameter of internal thread sizes, guarantee that flexible axle elbow 4 is by sleeve 3, the round flange diameter of sleeve 3 rear ends is less than pressing plate 5 diameter of bores, be convenient to relatively pressing plate 5 rotations of sleeve 3, round flange thickness is greater than pressing plate 5 endoporus hole depths, so that sleeve 3 is pressed on the multichannel valve body 7.
Just can realize the straight line motion of valve rod by operation flexible axle; When the flexible axle stroke need to be adjusted, as long as unclamp gland nut 6 and adjusting nut 2, turnbarrel 3 reached locking gland nut 6 and adjusting nut 2 behind the correct position.This mechanism structure is simple, and small volume is easy to adjust, and simultaneously valve rod is in the relative closure space, has avoided that valve rod collides with, wearing and tearing and corrosion.Satisfy the usage requirement of tractor and engineering machinery fully.
