Projector bracket for handling official business

Abstract

The invention discloses a projector bracket for handling official business. A frame plate and a base are included; a hollow-out plate is arranged on the inner side of the frame plate, and is providedwith a slide groove; two sliding pieces are connected in the slide groove in a sliding manner; a limiting block is welded to one side of the top of each of the two sliding pieces; and one side of eachlimiting block is located on the corresponding sliding piece and is in threaded connection with a screw. In the projector bracket for handling the official business, firstly, the limiting blocks aremoved and made to be attached to the side edges of a projector; then by twisting a rotary knob, a gasket is made to be closely fixed to the upper surface of the hollow-out plate, at the moment, the positions of the limiting blocks are limited, the structure is simple, lateral migration of the projector can be avoided, and therefore a certain protective effect is achieved for the projector; secondly, by rotating a rotating disk, a second bevel gear drives a first bevel gear to rotate, and therefore a lead screw is made to rotate, due to the rotating effect of the lead screw, a spiral sleeve slowly moves upwards, and therefore the purpose of adjusting the height of the projector bracket is achieved; and the structure is simple, operation saves labor and is convenient, and the lifting processis stable and reliable.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to an office projector bracket. Background technique [0002] A projector is an optical instrument that uses optical elements to enlarge the contour of a workpiece and projects it onto a video screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of a non-through hole and observe the surface of a part. Projection The instrument is especially suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc., with high inspection efficiency and easy use; it is widely used in measuring rooms and production workshops. This is especially true for the instrumentation and watch industry. [0003] However, there are still some deficiencies in the existing projector bracket. On the one hand, the struct...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some deficiencies in the existing projector bracket. On the one hand, the structure is single, and the side of the projector cannot be limited and fixed, and the protection is poor. On the other hand, the height adjustment structure is not stable. , and it is inconvenient to adjust. At the same time, the projector is in direct contact with the bracket, which leads to poor heat dissipation and makes the equipment unable to operate safely.
