Abstract
The utility model relates to a dustproof cover for a color wheel of a projector. The dustproof cover is characterized by comprising an aluminium alloy cover body (1) that can partially cover the color wheel, is equipped with an arc portion (2) and a square portion (3) and is positioned and connected with the inside of the projector, wherein the arc portion (2) and the square portion (3) match the profile of the color wheel. According to the technical solution, when the dustproof cover is mounted on the color wheel for uses, dust is prevented from entering an optical channel of the projector so as to avoid pollution of an optical path, and moreover, elements are prevented from being damaged due to high temperature when the projector is working, that is to say, heat can be dissipated effectively.
Description
Technical field
The utility model belongs to projector's accessory, is specifically related to a kind of color wheel of projecting camera dust cover.
Background technology
In recent years, projector's technology is more and more universal, has been widely used in fields such as teaching, scientific research and amusement.Projector adopts has powerful light source as projection source; therefore thermal value is very big; avoid high temperature for the protection component and damage, generally can offer big air inlet, and adopt device such as fan to force air intake; improve the radiating efficiency of projector; but so all be very easy to bring the dust in the outside air into projector inside, if these dusts enter optical channel, will have a strong impact on the image quality of projector; and cause failure rate to raise, reduce serviceable life etc.
Colour wheel is a kind of accessory of projector inside, is the device nearest apart from the optical channel entrance of projector, so the dust that accumulates above of colour wheel is very easy to enter optical channel when starting in projector, pollutes light path system.
The utility model content
The utility model provides a kind of color wheel of projecting camera dust cover, be installed on the colour wheel after, can prevent that dust from entering the projector light passage, avoids the pollution of light path; And damage component because of high temperature in the time of can avoiding projector's work, namely can efficiently radiates heat.
For achieving the above object, the technical solution adopted in the utility model is: a kind of color wheel of projecting camera dust cover, comprise that one can partly cover the aluminium alloy cover body of colour wheel, this aluminium alloy cover body has curved portions and the square department that matches with the colour wheel profile, and described aluminium alloy cover body is connected with the projector positioned internal.
Further, offer positioning screw hole on the described aluminium alloy cover body, be connected with the projector positioned internal through screw.
Further, described aluminium alloy cover body is provided with some aluminium alloy heat radiation wings, and this aluminium alloy heat radiation wing has hollow cavity, and the hollow cavity of aluminium alloy heat radiation wing is communicated with the cover inner chamber of described aluminium alloy cover body.
Further, the surface of described aluminium alloy cover body has electricity work layer.
Characteristics of the present utility model are: by at the outside dust cover of installing of color wheel of projecting camera, can avoid the dust accumulation of colour wheel, be subjected to contamination by dust and influence image quality with the light path of avoiding projector, can prolong the serviceable life of projector.Aluminum alloy material has high thermal conductivity coefficient, heat conduction is fast, it is good heat sink material, can avoid accumulation of heat, and density is little, in light weight, the aluminium alloy heat radiation wing that cooperates big surface, around namely the heat of colour wheel can being conducted rapidly and be dispersed into, be dispersed into rapidly in the surrounding air through projector's body cooling system again, strengthen radiating effect.The electricity work layer of aluminum_alloy cover surface can strengthen resistance to elevated temperatures, increases the service life.
Description of drawings
Fig. 1 is the structural representation of a kind of color wheel of projecting camera dust cover of the utility model embodiment.
In the above accompanying drawing: 1. aluminium alloy cover body; 2. curved portions; 3. square department; 4. positioning screw hole; 5. aluminium alloy heat radiation wing.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment: shown in accompanying drawing 1, a kind of color wheel of projecting camera dust cover, comprise that one can partly cover the aluminium alloy cover body 1 of colour wheel, this aluminium alloy cover body 1 has curved portions 2 and the square department 3 that matches with the colour wheel profile, offer positioning screw hole 4 on the aluminium alloy cover body 1, be connected with the projector positioned internal through screw.
Aluminium alloy cover body 1 is provided with some aluminium alloy heat radiation wings 5, and this aluminium alloy heat radiation wing 5 has hollow cavity, and the hollow cavity of aluminium alloy heat radiation wing 5 is communicated with the cover inner chamber of described aluminium alloy cover body 1.
