Described projector mounting box and the second rolling bearing axle center connect.
What reach has the technical effect that, is connected the angular adjustment realizing projector horizontal direction by the first rolling bearing, is realized the balance adjustment of projector by the second rolling bearing, and the elevation angle being realized projector by the 3rd rolling bearing is regulated.
Concrete, described support bar two-stage nitration includes entablature and sill, the sill of described support bar two-stage nitration and the 3rd rolling bearing axle center and is connected, and described second rolling bearing is arranged on the entablature of support bar two-stage nitration.
As optimal design, the sill midpoint of described support bar two-stage nitration is connected with the 3rd rolling bearing axle center, and described second rolling bearing is arranged on the entablature midpoint of support bar two-stage nitration.
Further, the Plane of rotation of described second rolling bearing and the Plane of rotation of the 3rd rolling bearing are mutually perpendicular to.
Further, the junction of described support bar two-stage nitration upper end and projector mounting box is provided with the first fixed screw；Owing to projector itself has certain weight, after therefore regulating the elevation angle of projector, it is necessary to fixed, the angle after modulation could be kept.
Preferably, described foot rest includes three adjustable for height expansion links, and described expansion link is evenly arranged with multiple limit spring pin；The balance adjustment of projector has been reached by the height of adjustable telescopic rod.
Further, described second rolling bearing and the 3rd rolling bearing are provided with the first fixed screw.
Further, hinged between described expansion link and base, its hinged place is provided with the second fixed screw.
Arrange fixed screw in order that fixing projector rack regulate after position.
Further, being provided with support member bottom described projector mounting box, described support member includes cross bar for " H " shape, and the cross bar of support member and the second rolling bearing axle center connect.
The beneficial effects of the utility model: compare with traditional projecting rack, the not only structure order of the projector rack in this programme, and processing ease when regulating, overcome existing projector rack and regulate inconvenient problem.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail:
As shown in Figure 1:
A kind of adjustable projector rack, is specifically provided with base 1, foot rest 2, projector mounting box the 3, first rolling bearing the 4, second rolling bearing the 5, the 3rd rolling bearing 6, strut one section 101 and support bar two-stage nitration 102；
In order to realize projector adjustment in the horizontal direction, above-mentioned first rolling bearing 4 is horizontally set on base 1, one section of 101 lower end of support bar is connected with the first rolling bearing 4 axle center, and the end face that support bar is a section 101 is circular so that support bar can upwards realize 360 ° of rotations in level for one section 101.
In order to realize the altitude mixture control of projector image, one section of 101 upper end of support bar is vertically arranged with the 3rd rolling bearing 6, support bar two-stage nitration 102 is connected with the 3rd rolling bearing 6 axle center, make support bar two-stage nitration 102 can realize 360 ° of rotations on perpendicular, reach to regulate the effect at the projector elevation angle, thus realizing the altitude mixture control of image；
As best design, support bar two-stage nitration 102 is made up of four edge strips for being designed as " mouth " type, is connected including entablature and sill and left and right crossbeam, the sill of described support bar two-stage nitration 102 and the 3rd rolling bearing 6 axle center；For making best results, the sill midpoint of described support bar two-stage nitration 102 is connected with the 3rd rolling bearing 6 axle center.
