Description
Technical field
The utility model is related to a kind of optical projection system, particularly a kind of optical projection system for covering large area view field.
Background technology
In certain situations it is desirable in four wall upslide projection pictures of some closing space, traditionally can typically set four
Projecting apparatus, respectively to should space four walls, while this four projecting apparatus need to be uniformly controlled commonly through control system,
To ensure the continuity of broadcasting pictures.This mode needs to use many projection arrangements, and cost is higher.
The content of the invention
The utility model is that design is ingeniously in order to solve the above-mentioned deficiency present in prior art, propose that one kind is simple in construction
It is wonderful, cost can be substantially reduced, but still the optical projection system of large area view field can be covered.
Technical solution of the present utility model is：A kind of optical projection system for covering large area view field, its feature
It is：Described optical projection system includes being arranged on that projecting direction is provided with supporting table 2 in projection chamber 1, supporting table 2 is upward
Projecting apparatus 3, is provided with reflecting mechanism on the ceiling of projection chamber 1, and described reflecting mechanism includes being fixedly connected with ceiling
Housing 4, be provided with electric rotating machine 5 in housing 4, electric rotating machine 5 is by gear driving pair and rotating support in housing 4
Rotating shaft 6 is connected, and the bottom of rotating shaft 6 is provided with support 7, and the bottom of the support 7 is provided with oscillating motor 8, the work of oscillating motor 8
Make end with swinging block 9 to be connected, described swing fast 9 is fixedly connected with the dorsal part of speculum 10, speculum 10 and the position of projecting apparatus 3
Match, and the inwall of the projection chamber 1 is perspective plane 11.
The utility model compared with the existing technology, has the following advantages that：
The optical projection system of this kind of structure type, is only coordinated with reflecting mechanism with projector equipment, just can realize according to
The secondary effect rung in multiple perspective plane upslide projections, can freely be rotated and at certain angle due to being provided with one in reflecting mechanism
The speculum swung in the range of degree, therefore adjustment gets up very convenient, compared to traditional similar optical projection system, can save significantly
The quantity of projector equipment is saved, while also without for a set of complicated control system of multiple projection device configurations, therefore, it is possible to big
Reduce cost greatly.It can be said that this optical projection system possesses a variety of advantages, it is particularly suitable for popularization and application in the art,
Its market prospects is very wide.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1：One kind can cover large area
The optical projection system of view field, the system includes a supporting table 2 being arranged in projection chamber 1, and throwing is provided with supporting table 2
Shadow instrument 3, the projecting direction of this projecting apparatus 3 upwards, reflecting mechanism is provided with the ceiling of projection chamber 1, this reflection machine
Structure includes the housing 4 being fixedly connected with ceiling, and fixation is supported by electric rotating machine 5 in housing 1, and electric rotating machine 5 passes through gear
Rotating shaft 6 of the transmission with rotating support in housing 4 is connected, and support 7 is provided with the bottom of rotating shaft 6, and the bottom of support 7, which is fixed, to be connected
Be connected to oscillating motor 8, the working end of this oscillating motor 8 is connected with swinging block 9, and described swinging block 9 then with speculum 10
Dorsal part be fixedly connected, the position of described speculum 10 and projecting apparatus 3 matches（I.e. on the projecting direction of projecting apparatus 3）,
All inwalls of projection chamber 1 are perspective plane 11 simultaneously.
The course of work of the optical projection system for covering large area view field of the utility model embodiment is as follows：Need
When the upslide of multiple perspective planes 11 of projection chamber 1 penetrates image frame, projecting apparatus 3, the light direct irradiation that projecting apparatus 3 is sent are first turned on
Onto speculum 10, under standard state, speculum 10 is with the horizontal 45 degree of angles, and such speculum 10 just can be by projecting apparatus 3
The picture of generation is reflexed on some perspective plane 11, it is necessary to when allowing the picture to be moved on multiple perspective planes 11, start rotation
Motor 5, electric rotating machine 5 drives rotating shaft 6 to rotate by gear driving pair, and the speculum of the bottom of rotating shaft 6 is connected to by support 7
10 also can concomitant rotation, and then light is reflexed on different perspective planes 11, frame out is presented on different perspective planes 11
Mobile dynamic viewing effect；
If the position of projection image has deviation, oscillating motor 8 can be driven to work, driven instead by swinging block 9
The swing that mirror 10 does minute angle is penetrated, and then adjusts the projected picture on perspective plane 11.
