Abstract

The invention provides a coarse-pitch one-dimensional vertical lifting adjustment rack which comprises a fixing sleeve, a sliding shaft, a screw, a pressing sleeve, a thread sleeve and a slide block, wherein the sliding shaft is inserted into a shaft hole of the fixing sleeve and can slide; one end of the slide block penetrates through a guide groove of the fixing sleeve and is fastened on the sliding shaft; the other end of the slide block is inserted into a spiral groove in the thread sleeve; the spiral groove drives the slide block to lift in rotating and drives the sliding shaft to slide and lift up and down; and the pressing sleeve is arranged at the upper end of the thread sleeve and fixed on the fixing sleeve by set screws, limits the thread sleeve, and only allows the thread sleeve to rotate around a shaft center of the sliding shaft. The one-dimensional vertical lifting adjustment rack has the structural advantages that the fastening is convenient and quick; the assembling is convenient; an overall span of the thread sleeve is small; the pitch is coarse; the lifting is adjusted more conveniently; and the sliding shaft works stably without swinging. The adjustment rack can adjust stably, conveniently and quickly in the vertical direction and is convenient to use and high in efficiency, and the vertical lifting is accurate.

Description

technical field

[0001] The invention relates to a vertical lifting adjustment mechanism in optical light path experiments, in particular to a large-pitch vertical lifting one-dimensional adjusting frame which does not deflect the axis during the adjustment and lifting process. Background technique

[0002] When studying the optical path arrangement of optical characteristics, it is a common requirement to adjust the optical components up and down. However, when the existing adjustment means are adjusted, the optical elements often have adjustment instability such as swinging and axial deflection, which makes it difficult to arrange the optical path and the adjustment is cumbersome. Due to these reasons, a lot of time is consumed only in the process of vertical adjustment of optical elements, resulting in low experimental efficiency and affecting the working mood of experimenters.

Examples

Embodiment Construction

[0017] The structure of the large-pitch vertical lifting one-dimensional adjusting frame of the present invention will be described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the large-pitch vertical lifting one-dimensional adjustment frame of the present invention includes a fixed sleeve 1, a sliding shaft 2, a screw 3, a pressure sleeve 4, a threaded sleeve 5, and a slider 6.

[0019] The sliding shaft 2 is inserted into the shaft hole of the fixed sleeve 1 and can slide, one end of the slider 6 passes through the guide groove of the fixed sleeve 1 and is fastened on the sliding shaft 2, and the other end of the slider 6 is inserted into the spiral groove in the threaded sleeve 5 , when rotating, the thread groove drives the slider 6 up and down, and drives the sliding shaft 2 to slide up and down, and the upper end of the threaded sleeve 5 is provided with a pressure sleeve 4, which is fixed on the fixed sleeve 1 by a set screw 7, ...
