The technical scheme adopted by the invention for solving the technical problems is as follows:
an apparatus for automatically and integrally adjusting a projector and a projector screen, comprising: the projector bracket (3) is provided with a planar base (9), four hydraulic lifting rods are connected to the periphery of the base, namely a first hydraulic lifting rod (4), a second hydraulic lifting rod (5), a third hydraulic lifting rod (6) and a fourth hydraulic lifting rod (7), a projector fixing bracket (3) is connected to the upper portions of the four hydraulic lifting rods, a screen mounting bracket extends from one side edge of the projector fixing bracket, a projection screen is mounted on the screen mounting bracket, a projector is arranged at the center of the projector fixing bracket and is arranged in front of the projection screen, an electric control cabinet is fixed on the base, and the electric control cabinet is respectively connected with the first hydraulic lifting rod (4), the second hydraulic lifting rod (5), the third hydraulic lifting rod (6) and the fourth hydraulic lifting rod (7), and the electric control cabinet can control the lifting of the first hydraulic lifting rod (4), the second hydraulic lifting rod (5), the third hydraulic lifting rod (6) and the fourth hydraulic lifting rod (7) independently or together.
Further, preferably, four rollers (10) are respectively arranged below the base (9) and are respectively connected with the first hydraulic lifting rod (4), the second hydraulic lifting rod (5), the third hydraulic lifting rod (6) and the fourth hydraulic lifting rod (7).
After the scheme is adopted, the screen and the projector can be lifted or inclined at the same time by means of the hydraulic lifting rod, so that a viewer can conveniently watch the screen, and the screen and the projector have a better effect.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
Drawings
The present invention will be described in detail below with reference to the accompanying drawings so that the above advantages of the present invention will be more apparent. Wherein,
FIG. 1 is a schematic structural diagram of an apparatus for automatically and integrally adjusting a projector and a projector screen according to the present invention;
FIG. 2 is a schematic structural diagram of an apparatus for automatically and integrally adjusting a projector and a projector screen according to the present invention;
fig. 3 is an electrical control schematic of the present invention for automatically adjusting the projector and the projector screen.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
As shown in fig. 1 and 2, an apparatus for automatically and integrally adjusting a projector and a projector screen includes: projector support 3, projector support has a planar base 9, just be connected with four hydraulic lifting rod again around the base, be first hydraulic lifting rod 4, second hydraulic lifting rod 5, third hydraulic lifting rod 6 and fourth hydraulic lifting rod 7 respectively, a projector fixed bolster 3 is connected again to four hydraulic lifting rod's top, and a screen mounting support is extended to a side of projector fixed bolster, and installs a projection screen on the screen mounting support, sets up a projector in the center department of projector fixed bolster, and the projector locates projection screen's the place ahead, fixes an electrical control cabinet on the base, just electrical control cabinet connects respectively first hydraulic lifting rod 4, second hydraulic lifting rod 5, third hydraulic lifting rod 6 and fourth hydraulic lifting rod 7, just electrical control cabinet can control first hydraulic lifting rod 4 alone or jointly, And the second hydraulic lifting rod 5, the third hydraulic lifting rod 6 and the fourth hydraulic lifting rod 7 are lifted.
Further, preferably, four rollers 10 are respectively disposed below the base 9 and respectively connected to the first hydraulic lifting rod 4, the second hydraulic lifting rod 5, the third hydraulic lifting rod 6 and the fourth hydraulic lifting rod 7.
The working principle of the invention is as follows:
the projector 1 is fixed on the projector bracket 3, the screen 2 is fixed and then powered on, the device starts to work, the projector power supply is turned on through the electric control cabinet 8, the projector 1 starts to work, and the height and the inclination of the projector and the screen can be adjusted through remote control.
And the height of the 4 hydraulic lifting rods is changed to change the lifting and the inclination of the projector and the screen, so that a satisfactory viewing angle is achieved for a viewer.
As shown in fig. 3, if the hydraulic lift lever is adjusted 4.5.6.7 at the same time, the lift of the projector and the screen can be adjusted, if the lift is adjusted 4.5 or 6.7, the left and right tilt of the projector and the screen can be adjusted, and if the lift is adjusted 4.6 or 5.7, the front and back tilt of the projector and the screen can be adjusted.
After the scheme is adopted, the screen and the projector can be lifted or inclined at the same time by means of the hydraulic lifting rod, so that a viewer can conveniently watch the screen, and the screen and the projector have a better effect.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
