Problems solved by technology

[0003] However, due to the limitation of the space structure, the above two mechanisms cannot realize transmission in all working environments of interlaced shaft transmission.
For example, when the space where the axis of the input end intersects the axis of the output end is narrow, it is difficult to design an angle adjustment mechanism that can ensure the mechanical strength of the components and fit into the limited space

Embodiment Construction

[0019] The words "upper", "lower", "left", "right" etc. used in the following to describe the orientation are based on the orientation shown in the drawings for the convenience of explanation. In the actual device, these Orientation may vary due to how the unit is positioned.

[0020] The structure description of the preferred embodiment of the nut-slider type angle adjustment mechanism of the present invention will be described below with reference to the accompanying drawings. Accompanying drawing shows the nut slider type angle adjustment mechanism of the present invention, wherein the body 18 is fixed, the input screw 1 is screwed with the moving nut 4, and the moving nut 4 can only move up and down in the body 18. The mobile nut 4 is seen as a zigzag from the cross-section, and an oblique chute 3 is respectively opened on its both sides. The two direction-changing sliders 19 are respectively embedded in the inclined chute 3 of the moving nut 4 , respectively forming a mo...

Abstract

The invention relates to an angle adjustment mechanism, in particular to a nut slider type angle adjustment mechanism, comprising a machine body, an input part, a turning part and an output part. A turning slider is inlaid into an oblique slippery slot of a moving nut to form a moving pair with the oblique slippery slot and is hinged with one end of an output pull rod by a turning pin shaft. The inner ring of a pull rod bearing is fixedly connected with the other end of the output pull rod by transitional fit, and the outer ring of the pull rod bearing is tightly pressed on the inner ring of an output slider. The output pull rod partly extends into a hollow input shaft by the supporting of a sliding bearing, and an output pin shaft enables the output slider in the hollow input shaft to be hinged with one end of a swash-plate connecting rod out of the hollow input shaft through a rectangular window. The other end of an output connecting rod is also hinged with the outer edge of a swash plate by a swash-plate pin shaft. Compared with the traditional displacement adjusting mechanism, the angle adjustment mechanism has the advantages that the reliability and the service life are greatly increased as a gear kind of wearing components are not used; meanwhile, interlaced shaft driving is realized; and the overall size of the mechanism is small and compact.

Description

technical field [0001] The invention relates to an angle adjustment mechanism, in particular to a nut slider type angle adjustment mechanism. Background technique [0002] Among the existing angle adjustment mechanisms, rack and pinion mechanisms and worm gear mechanisms are generally used for two-axis interlaced transmission. The Chinese utility model patent application with application number 20082017543.1 discloses an angle adjustment mechanism, which includes a base, a bearing unit and a first adjustment unit, the bearing unit is pivotally connected to the base, and the first adjustment unit has a first guide The rod assembly and the first adjustment assembly, the first guide rod assembly passes through the first adjustment assembly and connects the base and the bearing unit, adjusts the relative position of the first adjustment assembly and the first guide rod assembly, and the bearing unit is relative to the base along the second Turn in one direction. The utility mo...
