Problems solved by technology

When a certain amount of dust has accumulated on the fan part, its cooling capacity will drop significantly. This requires the projector to be disassembled for cleaning. structural damage
In addition, for ceiling-mounted projectors, when the installation height of the projector is low, accidental collisions will cause the projection direction to shift, and the body will vibrate for a long time. If the projector happens to be working at this time, it will seriously Affect the effect of projection display and bring inconvenience to ongoing meetings or teaching

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] An anti-shock quick return projector device, as attached figure 1 As shown, it includes a protective case 1; a projector 3 is fixedly arranged in the protective case 1; a filter device 2, an air inlet 31 and an air outlet 32 ​​are communicated with the protective case 1; the outlet end of the filter device 2 Corresponding to the position of the air inlet 31 of the projector 3, the air inhaled by the cooling fan can be pre-filtered, thereby reducing the accumulation of dust in the body of the projector 3 and keeping the heat dissipation capacity of the projector 3 at a high level for a long time. Reduce the frequency of dismantling and cleaning, reduce maintenance time and cost, and improve user experience;

[0036] as attached figure 2 As shown, the filter device 2 includes a ventilation pipe 21 and a spacer 22; the two ends of the ventilation pipe 21 are com...

Abstract

The invention discloses an anti-shock fast return projector device, which comprises a protective case; a projector is arranged in the protective case; a filter device is connected to the protective case; a suspension device is connected to the upper end of the protective case ; There is a rotating return device between the protective shell and the suspension device; the dust accumulation in the projector is reduced through the filter device, and the frequency of dismantling and cleaning is reduced; the filter passes through the mutual rotation and axial sliding of the two filter elements The internal dust can be quickly cleaned out, which improves the maintenance efficiency; the vertical impact buffer of the projection device is realized through the suspension device, and the height adjustment of the projection area is realized through the adjustment of the limit block and the installation hole; through The rotating back-to-alignment device realizes shock buffering in the horizontal direction, completes rapid positioning and back-to-alignment during rotation through the magnetic block attraction, and reduces the time of small tremors.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to an anti-shock fast return projection device. Background technique [0002] As a device that is easy to use and has good display effects, the projector is widely used in various occasions such as school teaching, conference office and home entertainment. Because the light-emitting structure in the projector generates a lot of heat while generating images, it is necessary to be equipped with a cooling fan to cool the body. When a certain amount of dust has accumulated on the fan part, its cooling capacity will drop significantly. This requires the projector to be disassembled for cleaning. Structural damage. In addition, for ceiling-mounted projectors, when the installation height of the projector is low, accidental collisions will cause the projection direction to shift, and the body will vibrate for a long time. If the projector happens to be working at this time, it will s...
