Title: PROJECTION DISPLAY DEVICE PROTECTION APPARATUS AND PROJECTION DISPLAY DEVICE
Abstract:
A projection display device protection apparatus and a projection display device, which are used to solve the technical problem that an exposed reflecting mirror (101) in a projection display device is easy to be damaged. The projection display device protection apparatus comprises a support (401), a base (402) and a protection curtain apparatus (201-203, 204a, 204b, 205-216, 219-220). The support (401) is fixed on the base (402), and a reflecting mirror (101) in the projection display device is fixed on the support (401). The protection curtain apparatus (201-203, 204a, 204b, 205-216, 219-220) is fixed in front of the reflecting mirror (101). A protection curtain (201) is arranged in front of the reflecting mirror (101); when the projection display device does not work, the protection curtain (201) is closed, so that the reflecting mirror (101) can be prevented from being damaged by accidental friction and collision; further, the reflecting mirror (101) can be protected from frequent dust accumulation by the protection curtain (201), so that the reflecting mirror (101) does not need to be frequently wiped, and the possibility that the reflecting mirror (101) is damaged can be lowered.
