Description

A kind of mounting structure of projector optical engine

Technical field

The utility model relates to projector optical engine mounting structure technical field, specifically a kind of projector optical The mounting structure of engine.

Background technique

Projector be it is a kind of the profile of workpiece is amplified using optical element, and the optics instrument being projected on shadow screen Device.Projector's temples construction can be divided into three systems: optical system, cooling system and circuit system, wherein with optical system Core the most, because it directly decides the attainable picture quality of institute, projector.Optical system is made of several parts One entirety, chip, camera lens, light path design etc. are all included.

But there is also defects for light engine mounting structure used in the prior art:

1) Installation Flexibility is poor, can not be adjusted flexibly the installation site of camera lens as needed, thus it is impossible to meet The demand that different projectors use；

2) safety is lower: when light engine installs fixed, simplest mode would generally be in the core of light engine at present On piece first drills, and is then fixed using bolt, and setting so easily makes chip impaired, influences its recycling.

Utility model content

In order to make up the above deficiency, the utility model provides a kind of mounting structure of projector optical engine, to solve The problems in above-mentioned background technique.

The technical solution of the utility model is: a kind of mounting structure of projector optical engine, including projector housing and Light engine ontology, the light engine ontology is which includes chip body and lens bodies, bottom in the projector housing Portion is provided with light engine fixed plate, and light engine fixed plate right forward side is provided with rectangular-shaped groove, the groove Interior bottom is arc setting, and its left and right sides of bottom is equipped with clip by fastening bolt jointly in the groove, described Bottom is stained with anti-skid rubber cushion in clip inner wall and groove, and light engine fixed plate outer is equidistant by fixing bolt C-clip is installed, and the c-clip is pushed against in chip body outer top, light engine fixed plate bottom is whole Change is provided with U-shaped support plate, and the U-shaped support plate bottom end is covered with buffer rubber gasket, the projector housing and U-shaped support Plate is installed by screw.

In this setting:

Dual mounting means enables to Installation Flexibility and adaptability to be promoted, and chip body does not need to hold during installation Damage risk brought by load drilling is fixed, thus safety is relatively higher, specifically:

1) when chip body is that L shape is arranged, lens bodies are placed on light engine fixed plate right forward side In groove, then clip is fixed by fastening bolt and is connected to lens bodies outer wall top, and bottom in clip inner wall and groove It is stained with anti-skid rubber cushion, the stability of lens bodies installation can be increased by the setting of anti-skid rubber cushion, at this time camera lens Main body can also assist pushing against chip body side；C-clip is fixed by fixing bolt as needed, consequently facilitating Installation is fixed in chip body, is reduced when tradition is fixedly mounted the step of being punched on chip, and light engine is fixed Plate top is equidistantly stained with the rubber washer positioned at fixing bolt outer, and c-clip bottom is stained with abutting in chip body The anti-skid bulge on outer top is convenient for individually being stablized chip body by the mutual cooperation of rubber washer and anti-skid bulge Clamping, while cooperating the setting of light engine fixed plate skidproof bottom rubber ring that can reduce fixing bolt and generate when in use and taking off Finally projector housing and U-shaped support plate are fixed from outer wall by screw again for a possibility that falling, consequently facilitating will throw Shadow casing body and the installation of light engine ontology are fixed；

2) when chip body is that rectangle turns setting, fastening bolt and clip are dismantled, and is supported by U-shaped Fastening bolt and clip are transferred to bottom in U-shaped support plate by the setting of location hole on plate, then by fastening bolt and clip Inside lens bodies transfer installation to U-shaped support plate, then c-clip is fixed by fixing bolt as needed, Consequently facilitating installation is fixed in chip body, reduce when tradition is fixedly mounted the step of being punched on chip, and optics Engine fixed plate top is equidistantly stained with the rubber washer positioned at fixing bolt outer, c-clip bottom be stained with abutting in The anti-skid bulge on chip body outer top is convenient for carrying out chip body by the mutual cooperation of rubber washer and anti-skid bulge Individually stablize clamping, while cooperating the setting of light engine fixed plate skidproof bottom rubber ring that can reduce fixing bolt and using When generate a possibility that falling off, finally projector housing and U-shaped support plate are fixed from outer wall by screw again, thus Convenient for projector housing and the installation of light engine ontology are fixed.

Preferably, light engine fixed plate top is equidistantly stained with the rubber washer positioned at fixing bolt outer, and The upper end of the fixing bolt is concordant with light engine dead plate upper end face.

Preferably, the c-clip bottom is stained with abutting in the anti-skid bulge on chip body outer top.

Preferably, it also offers at left and right sides of the U-shaped support plate and is spirally connected matched location hole, and institute with fastening bolt U-shaped support plate bottom face inner wall is stated as arc setting.

Preferably, the height of the U-shaped support plate is greater than the diameter of lens bodies rear end.

Preferably, the light engine fixed plate bottom face is also stained with the anti-slip rubber on the outside of fixing bolt Circle.
