Abstract
The utility model discloses an installation support of a projector device. The installation support of the projector device comprises a base fixed on a wall body. A horizontal-motion sliding rail is fixedly arranged on the base. A connection arm is fixedly connected with the horizontal-motion sliding rail. The installation support of the projector device is fixedly connected with the connection arm. Due to the fact that the horizontal-motion sliding rail is arranged on the installation support, after the base and the wall body are approximately fixed, the projector device can be horizontally moved by adjusting the horizontal-motion sliding rail, the aim of adjusting the projection focal length of the projector device is achieved, and the installation support of the projector device is particularly suitable for installation and use of a projector with the short focal length.
Description
Technical field
The utility model relates to a kind of mounting bracket of projection equipment.
Background technique
Along with developing rapidly of information technology, teaching content also realizes information-based gradually, existing classroom instruction much all has been equipped with electronic educational technology equipment, as projector, especially for emerging electronic interactive board of education, detector array type electronic white boards can be changed into can be interactive equipment, project image onto on the detector array type electronic white boards by projector and can also carry out interactive operation with hand or teacher's pointer simultaneously.Installation and use for the ease of the detector array type electronic white boards projector, generally all adopt short out-of-focus projection instrument, and the focal length of short out-of-focus projection instrument can not be adjusted, perhaps but adjusting range is less, therefore the distance of installing is had certain requirement, existing projector mount all adopts fixed form to be applicable to long out-of-focus projection instrument, if adopt existing projector mount, in case the short out-of-focus projection of setup error instrument just can not focus on by adjusting focal length, so use is very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of mounting bracket of novel projection equipment, is particularly useful for short out-of-focus projection instrument, can realize the adjustment of focal length by adjusting support.
The utility model is to realize above-mentioned purpose like this:
The mounting bracket of projection equipment comprises the base fixing with body of wall, and the translation slide rail is fixedly arranged on the base; Have link arm to fixedly connected with the translation slide rail, the scaffold of projection equipment is fixedlyed connected with link arm.
Wherein, be provided with the fine setting slide rail between described link arm and the scaffold.
Wherein, be uniformly distributed with a plurality of vertical adjusting hole on the described link arm, scaffold is fixed by latch and adjustment hole.
The beneficial effects of the utility model are: by the translation slide rail is set at mounting bracket, after base and body of wall almost fixed, can also make projection equipment carry out translation by regulating the translation slide rail, thereby reach the purpose of adjusting the projection focal length, especially suitable and short out-of-focus projection instrument is installed and used.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model structural drawing.
Embodiment
With reference to Fig. 1, the mounting bracket of projection equipment comprises the base 1 fixing with body of wall, and translation slide rail 2 is fixedly arranged on the base 1; Have link arm 3 to fixedly connected with translation slide rail 2, the scaffold of projection equipment is fixedlyed connected with link arm 3.By translation slide rail 2 is set at mounting bracket, after base 1 and body of wall almost fixed, can also make projection equipment carry out translation by regulating the translation slide rail, thereby reach the purpose of adjusting the projection focal length, especially suitable and weak point out-of-focus projection instrument is installed and used.
For the mounting bracket that adopts suspended ceiling to install, because translation slide rail 2 mounting points are higher, need use instruments such as ladder during adjustment, more easily the position of projector is regulated during for use, be provided with fine setting slide rail 5 between described link arm 3 and the scaffold.In general earlier behind the general position of determining good support with base 1 and wall mounted, and then regulate translation slide rail 2 focal length of projector cooperated substantially in projection screen, can also carry out the focal length fine setting by fine setting slide rail 5 at last and make drop shadow effect the clearest.
For adapting to different use occasions, be uniformly distributed with a plurality of vertical adjusting hole 4 on the described link arm, scaffold is fixed by latch and adjustment hole.Cooperate the height that just can adjust projector by latch and different vertical adjusting hole 4, very easy to use.
