The innovation point of the utility model is further described with reference to the accompanying drawings, as shown in fig. 2, the two protection boxes are respectively a protection box with 1 bevel edge and a protection box with 2 bevel edges, and the light projection glass (3) is fixed on one bevel edge of the protection box.
preferably, the further description is made by a protective box with 1 inclined edge, as shown in the attached fig. 3 and 4, the light projection glass (3) is arranged on a glass bracket (4), and the glass bracket (4) is fixed on the inclined edge of the protective box (1); in addition, optionally, the light projection glass (3) can also be directly fixed on the bevel edge of the protective box (1) by dispensing.
The light projection glass (3) is divided into two parts, one part is a transparent part (31), the other part is a silk-screen part (32), the silk-screen part (32) is opaque, the areas of the two parts are similar, and the projector (2) emits light from the transparent part (31); the light projection glass (3) is divided into two parts, so that the transparent area required by projection of the projector (2) is only one part of the whole light projection glass (3), and if the screen printing part (32) is not arranged and the whole light projection glass is transparent, all components and wires in the protective box (1) are directly transparent and visible, and the integral attractiveness is influenced.
When the light projection glass (3) is installed on the glass support (4), the glass support (4) is rectangular, and the light projection glass can still be installed after being rotated by 180 degrees, except that the positions of the glass transparent part (31) and the silk-screen printing part (32) are changed; if the transparent part (31) faces upwards and the silk screen printing part (32) faces downwards, the exit port of the projector (2) is positioned at the upper part; when the glass bracket (4) is rotated by 180 degrees, the transparent part (31) faces downwards, and the silk screen printing part (32) faces upwards, the exit port of the projector (2) is located at the lower part; the projector (2) is fixed on the projector bracket (5), and the position and the projection direction of the projector (2) can be changed by adjusting the up-down position of the projector bracket (5).
In actual use, according to the position of the protective box (1) on the site and the projection direction of the projector (2), the relative positions of the silk screen part (32) and the transparent part (31) of the light projection glass (3) can be adjusted according to needs, and the position of the projector (2) is adjusted by adjusting the position of the projector bracket (5) in a following manner.
As shown in fig. 4, it is preferable that the hydraulic rod (6) is used to adjust the up-down position of the projector bracket (5) with least effort, and at this time, one end of the projector bracket (5) is fixed on the protective box (1) and the other end is connected with the hydraulic rod (6); one end of the hydraulic rod (6) is also fixed on the protective box (1), and the other end is fixed on the projector bracket (5).
In the following, the difference between the conventional rectangular parallelepiped protection box and the bevel edge protection box of the present invention will be further explained from the aspects of both the projection angle and the volume of the protection box, and for the convenience of description, the light projection glass of the rectangular parallelepiped protection box is defined as straight-edge glass (33), and the light projection glass of the present invention is defined as bevel-edge glass (34).
As shown in fig. 1, when the projector projects from the straight-edge glass (33), the projection angle of the projector changes within a range of β, that is, between the exit angle 1 and the exit angle 2, because when the projector projects from the position of the exit angle 1, the projected edge light ray 1 is already positioned at the uppermost part of the straight-edge glass (33), and if the position of the projector (2) is changed to move the projection angle upwards, the light emitted by the projector (2) is partially blocked by the top of the straight-edge glass (33). Similarly, if the position of the projector (2) is changed to move the projection angle of the projector to the lower part of the emission angle 2, the light emitted by the projector (2) is partially blocked by the bottom of the straight-edge glass (33), and if the range of the projection angle β is to be enlarged, the height H1 of the straight-edge glass (33) needs to be increased, and the volume of the protective box (1) is also increased.
As shown in fig. 5, when the projector (2) is in the same position and reaches the same projection angle range β, the required height of the bevel glass (34) is only H2, and it can be simulated by the illustration that when the projection angle range is the same as β, the height ratio is H2/H1=0.67, i.e. the volume of the bevel glass (32) protective box is reduced by 33% compared with the volume of the straight glass (33).
It is understood that when H1= H2, even if the vertical height of the hypotenuse glass (34) is the same as that of the straight-side glass (33), the projection range of the hypotenuse glass (34) is much larger than that of the straight-side glass (33), that is, a wide-angle projection effect is achieved.
In addition, it can be understood that when the projector (2) is used outdoors at present, most of the projectors (2) are projected to buildings, tree landscapes or the ground, namely non-horizontal or vertical projection, because most of the projectors cannot be at the same height as the projector to achieve horizontal projection or at the position right below the projector to achieve vertical projection, the position of the projector is changed to be inclined in the actual use state, and then the projector is projected through the vertical glass, namely the actual application value of the vertical glass (33) is lower than that of the bevel edge glass (34).
And simultaneously, the utility model discloses a protective housing (1), light projection glass (3) divide into silk screen printing part (32) and transparent part (31) two parts, and not the perpendicular glass of traditional monoblock perspective inner structure and wire rod, have beautified the whole outward appearance aesthetic feeling of protective housing greatly, can be as required when the in-service use, change the rotatory 180 degrees of position close-fitting glass support of projector through the hydraulic stem, can reach and compromise the outward appearance and throw the wide purpose of angle.
The above embodiments are only for further illustration of the technical solution of the present invention, and do not limit the protection scope of the present invention. It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
