Problems solved by technology

[0003] The projection lamp of the existing projector is usually exposed, which increases the probability of dust adhering to the projection lamp, which will affect the projection effect of the projection lamp. Not only that, but the existing projector is generally placed directly on the desktop , if the desktop is tilted, it will cause the equipment to tilt, so that the projected picture is tilted, which greatly affects the projection effect and reduces the practicability of the existing projector

Embodiment Construction

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0026] like figure 1 As shown, a dust-proof projection device with leveling function includes a main body 1, a support plate 3, a base 4, a projection lamp 2, a dust-proof mechanism and two leveling mechanisms. The main body 1 is fixed on the support plate. Above 3, two leveling mechanisms are respectively arranged on both sides below the support plate 3, the support plate 3 is arranged above the base 4 through the leveling mechanism, and the projection lamp 2 is fixed on the main body 1, so the The main body 1 is provided with a PLC, and the dust-proof mechanism is arranged on the main body 1;

[0027] PLC, i.e. programmable logic controller, uses a type ...

Abstract

The invention relates to a dust-proof projection device with a leveling function, which includes a main body, a support plate, a base, a projection lamp, a dust-proof mechanism and two leveling mechanisms, and the leveling mechanism includes a drive assembly, a bracket and two A spring, the dust-proof mechanism includes a transmission assembly, a cover plate, a power assembly, two filter screens and two moving assemblies, the moving assembly includes a sealing plate and a connecting rod, the dust-proof projection device with a leveling function Through the dust-proof mechanism, the dust-proof function is realized to prevent dust from adhering to the projection lamp and affecting the projection effect. Through the leveling mechanism, the function of adjusting the horizontal state of the support plate is realized to avoid equipment tilting and affect the projection effect.

Description

technical field [0001] The present invention relates to the field of projection equipment, in particular to a dust-proof projection device with a leveling function. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are currently widely used in homes, offices, schools and entertainment places. According to different working methods, there are different types such as CRT, LCD, DLP and so on. [0003] The projection lamp of the existing projector is usually exposed, which increases the probability of dust adhering to the projection lamp, which will affect the projection effect of the projection lamp. Not only that, the existing projector is generally placed directly on the desktop. , If the desktop is tilted, the device will be tilted, so that the ...
