[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 perform drilling operations. 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

The invention relates to a projection screen installation and positioning device for multimedia equipment, which includes a base, an adjustment mechanism, a measuring ruler, a sliding bottom plate and a lifting mechanism. The upper end surface of the base is symmetrically provided with sliding bottom plates front and rear through sliding fit, and the sliding bottom plates are arranged There is an adjustment mechanism, the upper end surface of the base is located on the right side of the sliding bottom plate, and a measuring ruler is provided, and the upper end of the sliding bottom plate is provided with a lifting mechanism; the present invention can solve the existing problem: the process of measuring and positioning the drilling position is cumbersome, which affects the projection screen of multimedia equipment. Efficiency of installation: Usually, it is necessary to step on the upper end of the ladder and use a hand-held electric drill to carry out the drilling operation. The driller needs to apply a tight force to the electric drill, which makes the center of gravity of the ladder unstable, causing the driller to carry out the work on the wall. There are problems such as potential safety hazards of slipping and falling during the installation of the hook.
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...
