Abstract

The invention discloses a protection device for a digital media playing device, which comprises a box body, a stand column, a mounting plate, a fixing hole, an opening and closing mechanism, a clamping mechanism, a sealing cover, a power line and a control switch.The opening and closing mechanism and the clamping mechanism are optimally arranged, and the driving motor is used as a power source; The driving gear enables the driven gear to drive the power gear to rotate, the power gear enables the special-shaped fluted disc to drive the gear column to rotate through the small gear, and thereforethe gear column drives the flower-shaped pieces to rotate mutually to achieve closing and opening, and a lens imaging position of the digital media playing device can be protected. A servo motor is used as a power source, a rotating gear drives a clamping rod to rotate through rotating fit of a threaded column in an inner threaded sleeve, then the digital media playing device can be rapidly clamped and fixed, and rapid adjustment can be carried out when the installation position of the digital media playing device deviates.

Description

technical field [0001] The invention relates to the related field of digital media, in particular to a protective device for a digital media player. Background technique [0002] Digital media refers to information carriers that record, process, disseminate, and acquire processes in the form of binary numbers. These carriers include digitized text, graphics, images, sounds, video images, animations, and other sensory media, as well as expressive media that represent these sensory media. (encoding), etc., commonly known as logical media, and physical media that store, transmit, and display logical media. Digital media platforms focus on providing services to customers / users; traditional digital media playback devices are mostly used to play clear images. When the media playback device is installed, it is necessary to install a protective device to protect the digital media playback device from bumping and damage. [0003] The protection device of the prior art digital media ...
