Multi-media audio-visual installation auxiliary device

Abstract

The invention discloses a multi-media audio-visual installation auxiliary device. The multi-media audio-visual installation auxiliary device comprises a moving platform and an angle adjusting device.A lifting device is fixedly arranged in the middle of the moving platform, the angle adjusting device is fixedly arranged at the output end of the lifting device, and a multi-media device is fixedly arranged at the output end of the angle adjusting device. The angle adjusting device comprises a base and a double-head motor. The base is fixed to the output end of the lifting device, and the double-head motor is fixed to the base. The output ends on the two sides of the double-head motor correspondingly stretch into a first transmission case and a second transmission case to conduct transmissionconnection, and the output ends of the first transmission case and the second transmission case are connected with a transmission assembly through a first shaft. The transmission assembly comprises asecond shaft, a differential stroke adjusting device and a first lifting assembly. The first shaft is rotated, and therefore the end portion of the output end of the first lifting assembly can be higher or lower than the end portion of the output end of a second lifting assembly, and the included angle between an installation platform and the horizontal plane can be changed.

Description

technical field [0001] The invention specifically relates to the technical field of multimedia auxiliary devices, in particular to a multimedia audio-visual installation auxiliary device.

[0002] With the development and unification of computer technology and network technology, it has become the trend of modern multimedia development. The so-called multimedia refers to the comprehensive expression of information formed by the fusion of various media, including the fusion of text, sound and images. Therefore, the use of computer Cooperate with a projector to form a relatively mature multimedia audio-visual equipment. When installing multimedia audio-visual equipment, auxiliary devices can be used to assist the installation of audio-visual devices. Projection angle, specifically speaking, it is convenient to adjust the projection angle of the projector. At present, the existing multimedia audio-visual installation auxiliary devices are usually brackets with relatively simple structures. Although their cost is relatively low, they cannot be quickly and automatically Adjusting the placement angle of multimedia audio-visual equipment cannot adapt to the development of the market
