Involved in the numerous patents document, as Publication No. CN205942235U, CN208207496U, CN207051639U,
The patent document of CN205982962U discloses their installations and operating mode, therefore the displosure common sense is no longer described in detail.
Innovative point of the invention is further detailed with reference to the accompanying drawing, such as attached drawing 2, two kinds of protective housings are respectively
The protective housing of 1 bevel edge and the protective housing of 2 bevel edges, light projection glass (3) are fixed on a bevel edge of protective housing.
Preferably, it is further described with the protective housing of 1 bevel edge, as shown in the attached drawing 3 and attached drawing 4, light projection
Glass (3) is installed on glass supporter (4), and glass supporter (4) is fixed on the bevel edge of protective housing (1)；It is, moreover, an optional that light
Projection glass (3) can also directly dispensing be fixed on the bevel edge of protective housing (1).
Light projection glass (3) is divided into two parts, and a part is transparent part (31), and another part is silk-screen part
(32), silk-screen part (32) are opaque, and two-part area is close, and projector (2) is emitted from transparent part (31)；Light
Projection glass (3) be divided into it is two-part be advantageous in that because projector (2) project required for transparent region be monolith light
The a part for projecting glass (3), if there is no silk-screen part (32), and it is entirely transparent, then all inside protective housing (1)
Component and the direct transparent visual of electric wire, influence overall beautiful.
When light projection glass (3) is mounted on glass supporter (4), glass supporter (4) is rectangle, after rotating 180 ゜
It can still install, the difference is that the position of glass transparent part (31) and silk-screen part (32) becomes；If transparent part
(31) upward, silk-screen part (32) downward, then the exit portal of projector (2) is located in top；When glass supporter (4) rotate
After 180 ゜, transparent part (31) downward, silk-screen part (32) upward, then the exit portal of projector (2) is located in lower part；Projection
Machine (2) is fixed on projector's bracket (5), and the upper and lower position for adjusting projector's bracket (5) can change the position of projector (2)
And projecting direction.
In actual use, the projecting direction according to protective housing (1) in the position in place and projector (2), can basis
Need to adjust the silk-screen part (32) of light projection glass (3) and the relative position of transparent part (31), the position of projector (2)
Then adjusted by adjusting the location following of projector's bracket (5).
As shown in Fig. 4, it is preferred that cooperated using hydraulic stem (6) adjust projector's bracket (5) upper and lower position when most
Laborsaving, projector's bracket (5) one end is fixed on protective housing (1) at this time, and one end is connected with hydraulic stem (6)；And hydraulic stem (6) one
End is also to be fixed on protective housing (1), and one end is fixed on projector's bracket (5).
To hereinafter be further illustrated in terms of crevice projection angle and protective housing volume two traditional cuboid protective housing and
The difference of bevel edge protective housing of the present invention, for ease of description, the light projection glass for defining cuboid protective housing herein is straight
Side glass (33), and define light projection glass of the invention and be referred to as bevelled glass (34).
As shown in Fig. 1, when projector projects away from straight flange glass (33), its crevice projection angle variation range is β, i.e.,
Between shooting angle 1 and shooting angle 2, because the rim ray 1 of projection is when it is projected from 1 position of shooting angle
Topmost positioned at straight flange glass (33) makes its projectional angle again toward moving up, then projecting if changing the position of projector (2)
The light of machine (2) outgoing will appear part by phenomenon light-blocking at the top of straight flange glass (33).Similarly, if changing projector (2)
Position, make its projectional angle toward moving below shooting angle 2, then the light of projector (2) outgoing also will appear part by straight flange
The light-blocking phenomenon in glass (33) bottom just needs if to expand the range of projectional angle β by the height of straight flange glass (33)
H1 is increased again, then while also increases the volume of protective housing (1).
As shown in Fig. 5, projector (2) reaches same crevice projection angle range beta in same position, required oblique
The height of side glass (34) is only H2, can be simulated by diagram, when crevice projection angle range is both β, highly compare H2/H1
=0.67, the i.e. volume-diminished of the volume ratio straight flange glass (33) of bevelled glass (32) protective housing 33%.
It is understood that as H1=H2, even if the vertical height of bevelled glass (34) is vertical with straight flange glass (33)
When highly identical, then the projection scope of bevelled glass (34) can be much larger than straight flange glass (33), that is, achieve the effect that wide-angle projects.
Further it will be understood that in the open air of current projector (2) in use, most projectors (2) are all to throw
It is mapped to building, treescape perhaps i.e. non-horizontal or perpendicular projection on ground, because most projectors will not be just
Accomplish that the height as missile projects to realization level, or just in missile vertical lower to realize vertical throw
It penetrates, so under real use state, is all that change the position of projector be inclination, is then projected away again by vertical glass,
I.e. the practical application value of vertical glass (33) is smaller than bevelled glass (34) practical application value instead.
Meanwhile protective housing (1) designed by the present invention, light projection glass (3) are divided into silk-screen part (32) and hyalomere
Point (31) two parts, rather than the vertical glass of traditional a monolith see-through internal structure and wire rod, have beautified protection significantly
Case overall appearance aesthetic feeling, in actual use can be as needed, changes the position tight fit glass branch of projector by hydraulic stem
Frame rotates 180 ゜, that is, can reach and take into account appearance and the wide purpose of crevice projection angle.
Above embodiments are only that technical scheme is described further, the protection model being not intended to limit the present invention
It encloses.It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from
In the case where spirit or essential attributes of the invention, the present invention can be realized in other specific forms.
