The connection of your mirror 30, other end buckle closure is in the first magnetic substance 51, so that 53 band of the second magnetic substance is realized in the sliding by crank 57
The swing of dynamic first magnetic substance 51, so that connecting rod 59 drives Fresnel mirror 30 to swing, the company of can be set according to actual needs
The length of bar 59 reaches preferable drop shadow effect to adjust the transmission of light.
The present invention also proposes a kind of projection device 200, the ray machine 100 including cabinet 201 and in the cabinet 201.
The specific structure of the ray machine 100 is referring to above-described embodiment, since this photographic equipment uses whole skills of above-mentioned all embodiments
Art scheme, therefore at least all beneficial effects brought by the technical solution with above-described embodiment, this is no longer going to repeat them.
Wherein, cabinet 201 is formed with installation cavity 201a, and in being equipped with control element (not shown) in installation cavity 201a,
Ray machine 100 is installed in installation cavity 201a, and is electrically connected with control element, to complete the automatic control of projection.Accordingly, it is
Realize the heat dissipation of cabinet 201 internal heat generation element, cabinet 201 offers multiple heat release holes (not indicating), to guarantee that projection is set
Standby 200 performance is stablized.In the first point of embodiment of corresponding driving assembly 50, handle 55 is inserted into holding tank 17, is held
Plate 551 directly abuts the outer surface of cabinet 201, to facilitate adjusting correction distortion.In order to increase handle 55 and the second magnetic substance
53 connective stability, the inner surface of handheld board 551 are additionally provided with grab 551a, when the inner wall of handheld board 551 abuts cabinet 201
When outer surface, grab 551a hook is set to the inner surface of cabinet 201, improves the structural stability of handle 55, while cabinet 201 opens up
There is avoid holes 201b, so that handle 55 can be moved along avoid holes 201b realizes moving for the second magnetic substance 53.Corresponding driving assembly
In 50 second point of embodiment, cabinet 201 also offers avoid holes 201b, so that crank 57 is exposed to outside, convenient for hand-held
It is slided, and then adjusts the position of the second magnetic substance 53.
The foregoing is merely alternative embodiments of the invention, are not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
