Problems solved by technology

Although this adjustable height pad can achieve the effect of stepless height adjustment, due to the limitation of the structural characteristics of the parallelogram mechanism itself, there is also a left and right displacement while realizing the height adjustment up and down, so the space used is relatively large, and cannot Use in small spaces

Abstract

The invention relates to a stepless height-adjusting supporter, comprising a spiral rotation body the two ends of which are respectively left-handed thread and right-handed thread; the two ends of the spiral rotation body are respectively provided with a left-handed thread cushion block and a right-handed thread cushion block which are matched with the spiral rotation body; a synchronizer which is arranged between the left-handed thread cushion block and the right-handed thread cushion block leads the left-handed thread cushion block and the right-handed thread cushion block to synchronously rotate correspondingly to the spiral rotation body. Owning to the synchronizer, the left-handed thread cushion block and the right-handed thread cushion block can be ensured to simultaneously move inwards or outwards along the axis line when the spiral rotation body rotates. According to different supporting requirements, different auxiliary transition supporters can be arranged on the left-handed thread cushion block and the right-handed thread cushion block, thus enlarging the application range of the stepless height-adjusting supporter. When the spiral structure is adopted to realize the stepless height adjustment, as the spiral structure has the characteristic that the spiral structure can only move in the axis line direction, the structure is compact and the stepless height-adjusting supporter can be convenient for use even in narrow space.

Description

technical field [0001] The invention relates to a stepless height adjustment support. Background technique [0002] Chinese patent specification CN200620146897.X discloses an adjustable height block for machining, which adopts a parallelogram structure, and an included angle locking device is installed between at least one group of adjacent sides. When using, loosen the locking device first, and then lock it when it is adjusted to a suitable height. Although this adjustable height pad can achieve the effect of stepless height adjustment, due to the limitation of the structural characteristics of the parallelogram mechanism itself, there is also a left and right displacement while realizing the height adjustment up and down, so the space used is relatively large, and cannot Use in narrow spaces. Contents of the invention [0003] The object of the present invention is to provide a stepless height adjustment support with various functions, wide application range and compac...
