The invention relates to the technical field of projection equipment, in particular to digital media projection equipment which comprises a base, pull plates are connected to the outer walls of the two sides of the base, threaded rods are connected to the inner walls of the two ends of the transverse symmetry axis of the top of the base, first rotating shafts are connected to the bottoms of the threaded rods, and sliding blocks are connected to the bottoms of the first rotating shafts. A sliding block is connected to the top of the base, steering rollers are connected to the two ends of the bottom of the sliding block, a second rotating shaft is connected to the center of the top of the base, a rotating rod is connected to the center of the top of the second rotating shaft, and a threaded column is connected to the top of the rotating rod. Meanwhile, the projection structure above the bottom box can move up and down along with the bottom box, so that the function of adjusting the height of the whole equipment is achieved, the height of the equipment can be adjusted according to the height of a screen, and the problems and defects in an existing device are effectively solved.
本发明涉及投影设备技术领域,尤其涉及一种数字媒体投影设备,包括底座,底座两侧外壁均连接有拉板,底座顶部横向对称轴两端内壁均连接有螺纹杆,螺纹杆底部均连接有第一转轴,第一转轴底部均连接有滑块,滑块底部两端均连接有转向滚轮,底座顶部中心处连接有第二转轴,第二转轴顶部中心处连接有转杆,转杆顶部连接有螺纹柱,本发明中通过设置螺纹柱与底箱之间的连接方式,使得底箱可以在转动的螺纹柱外壁上下移动,同时底箱上方的投影结构也会跟着一起上下移动,从而起到调节整个设备高度的作用,此时便可以根据屏幕的高度对设备的高度进行调节,从而有效的解决了现有装置中出现的问题和不足。
