Multimedia equipment projection curtain installing and positioning device

Abstract

The invention relates to a multimedia equipment projection curtain installing and positioning device. The multimedia equipment projection curtain installing and positioning device comprises a base, an adjusting mechanism, a measuring scale, sliding bottom plates and a lifting mechanism, the upper end surface of the base is provided with the sliding bottom plates in a front-back symmetry mode through sliding fit, and the adjusting mechanism is arranged between the sliding bottom plates. The measuring scale is arranged on the upper end surface of the base and located on the right sides of the sliding bottom plates, and the lifting mechanism is arranged at the upper ends of the sliding bottom plates. The device can solve the problems that the process of measuring and positioning the drilling position is tedious, and the installing efficiency of a multimedia equipment projection curtain is affected; and usually, a drilling worker needs to step on the upper end of a ladder type object and hold an electric drill with a hand to conduct drilling operation, the gravity center of the ladder type object is unstable due to the fact that the drilling worker needs to exert abutting force on the electric drill, and the potential safety hazard that the drilling worker slips and falls down in the process of installing a hook on a wall is caused.

Description

technical field [0001] The invention relates to the field of projection screen installation, in particular to a projection screen installation and positioning device for multimedia equipment. Background technique [0002] The projection screen is a tool used to display images and video files in movies, offices, home theaters, large conferences and other occasions. The projection screen for multimedia equipment usually has the function of electric winding and retracting. Therefore, when installing the projection screen for multimedia equipment, it is usually only necessary to hang the two ends of the rolled projection screen on the wall. The existing technology is usually hand-held. Drill holes on the surface of the wall with an electric drill, then install the hooks required for hanging the curtain, and then hang the projection screen on the hooks to complete the installation of the projection screen for multimedia equipment; [0003] However, the following problems usually...

AI Technical Summary

Problems solved by technology

[0004] 1. Before drilling the wall, it is usually necessary to measure and mark the position of the drilled hole multiple times, and the process of measuring and locating the drilled hole position is relatively cumbersome, resulting in the measurement and positioning work before drilling affecting the projection of multimedia equipment Efficiency of screen installation;

[0005] 2. In the prior art, when drilling a wall, it is usually necessary to step on the upper end of a ladder and use a hand-held electric drill to carry out the drilling operation. During this process, it is easy to cause the driller to use the electric drill due to the need to apply a tight force. The center of gravity of ladders and other objects is unstable, which leads to the safety hazard of slipping and falling when drilling personnel install hooks on the wall before installing the projection screen
