Description
Technical field
The utility model relates to a kind of multimedia-assisted equipment, particularly relates to a kind of telescopic multimedia projector erecting frame.
Background technology
Projector in multimedia equipment also known as projector, be a kind of can by image or VIDEO PROJECTION to the equipment on curtain, same to computing machine, VCD, DVD, BD, game machine, DV etc. can be connected and play corresponding vision signal by different interfaces.Projector is widely used in family, office, school and public place of entertainment, and different according to working method, have CRT, LCD, DLP etc. are dissimilar.But projector of the prior art is all hard-wired, just bad adjustment after having fixedly mounted, but also take up room, therefore, needs a kind ofly can be convenient to regulate and the bracket of projector that do not take up room when not using projector.
Utility model content
The purpose of this utility model is just to provide a kind of telescopic multimedia projector erecting frame to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises projector, intersection expansion link, slide bar, pull bar, motor and projector's erecting frame, the upper end of described intersection expansion link is flexibly connected with ceiling, ceiling is provided with sliding tray, described slide bar be connected with described one end intersecting expansion link be placed on described ceiling sliding tray in, described motor is installed on described ceiling, described pull bar is connected between the rotating shaft of described slide bar and described motor, the lower end of described intersection expansion link is flexibly connected with described projector erecting frame, and described projector is installed on described projector erecting frame.
Particularly, the rotating shaft of described motor is connected by meshing with between described pull bar.
The beneficial effects of the utility model are:
The utility model is a kind of telescopic multimedia projector erecting frame, compared with prior art, the utility model adopts motor automatically to regulate the lifting of projector, thus convenient adjustment, and when not using, projector can be risen, thus not taking up room, easy to use, there is the value applied.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: expansion link, 3-slide bar, 4-pull bar, 5-motor, 6-ceiling, 7-projector erecting frame are intersected in 1-projector, 2-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises projector 1, intersection expansion link 2, slide bar 3, pull bar 4, motor 5 and projector's erecting frame 7, the upper end of intersection expansion link 2 is flexibly connected with ceiling 6, ceiling 6 is provided with sliding tray (unmarked in figure), slide bar 3 with intersect one end of expansion link 2 be connected be placed on ceiling 6 sliding tray in, motor 5 is installed on ceiling 6, pull bar 4 is connected between the rotating shaft of slide bar 3 and motor 5, intersecting the lower end of expansion link 2 is flexibly connected with projector erecting frame 7, projector 1 is installed on projector's erecting frame 7, the rotating shaft of motor 5 is connected by meshing with between pull bar 4.
Principle of work of the present utility model is as follows:
As shown in Figure 1: when the utility model is implemented, drive pull bar 4 by the rotation of motor 5, pull bar 4 is with moving slide-bar 3 to move, thus intersection expansion link 2 is extended, and regulate projector 1 to move down, otherwise reverse motors 5 makes projector 1 up move.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
