Abstract

The invention provides a projector bracket which comprises a bottom plate, an outer hanging bracket rod, an inner hanging bracket rod, a connecting disk, a control mechanism and a telescopic cross rod. The bottom plate is fixed to a ceiling. The lower portion of the bottom plate is connected with the outer hanging bracket rod. The control mechanism is arranged on the outer hanging bracket rod. The control mechanism comprises a drive motor, a coupling and a speed reducer, wherein the speed reducer and the outer hanging bracket rod are provided with a common power shaft; the two sidewalls of the outer hanging bracket rod are both provided with multiple outer through holes. The inner hanging bracket rod downwards extends out of the interior of the outer hanging bracket rod. The two sidewalls of the inner hanging bracket rod are provided with inner through holes corresponding to the outer through holes. The outer through holes and the inner through holes are connected through fixing screws. The lower portion of the inner hanging bracket rod is connected with the telescopic cross rod. The lower portion of the telescopic cross rod is provided with the connecting disk used for being connected with a projector. By adopting the adjustable suspended type projector bracket, ascending and descending adjustment and distance adjustment can be achieved, the projector can be horizontally rotated to the direction where projection is needed, and various projection requirements can be met.

Description

A kind of projector mount

Technical field

The present invention relates to a kind of projector, specifically a kind of projector mount.

Background technology

Projector is as the instrument of a kind of meeting, teaching, it is widely used at present, usually it is placed directly on desk or is arranged on meeting room or the ceiling in classroom, as a special use space, suspention is a kind of beyond doubt method easily on the ceiling, but common projector mount is all directly install position, cannot move, it is suitable only for a kind of projector to project on a fixed-direction, if and change other model projector or wish conversion projecting direction, then cannot carry out.

Summary of the invention

For solving above-mentioned technical problem, a kind of projector mount provided by the invention is capable of lift adjustment and far and near adjustment, and can horizontally rotate the direction needing projection, meets multiple projection demand.

The technical solution adopted in the present invention is: a kind of projector mount, including base plate, the outer bar of suspension bracket, bar in suspension bracket, connection dish, controlling organization, telescopic cross bar, base plate is fixing on the ceiling, base plate is connected below the outer bar of suspension bracket, the outer bar of suspension bracket arranges controlling organization, controlling organization includes drive motor, shaft coupling, decelerator, decelerator has common line shaft with the outer bar of suspension bracket, suspension bracket is equipped with multiple accessibke porosity on outer bar two side, bar in suspension bracket is extended downwardly from inside the outer bar of suspension bracket, in suspension bracket, bar two side is provided with the inner via hole corresponding with accessibke porosity, accessibke porosity and inner via hole are connected by fixed screw, in suspension bracket, bar is connected below telescopic cross bar, telescopic cross bar is arranged below the connection dish for connecting projector.

Outside described connection dish, dirt seal housing is installed.

It is provided with automatically-controlled door before described dirt seal housing.

The invention has the beneficial effects as follows: under the drive of motor, the outer bar of suspension bracket can horizontally rotate, realize the projection of diverse location within doors, meet user and wish the demand of conversion projected position, meanwhile, telescopic cross bar is set, regulates the projector distance to curtain, remain able to project clearly after making to shift one's position, and adjustment far and near after meeting the projector changing new model. Suspension bracket also has the through hole of regulatory function up and down, is adjusted in vertical direction.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

1. base plate, the 2. outer bar of suspension bracket, 3. drive motor, 4. accessibke porosity, 5. fixed screw, 6. bar in suspension bracket, 7. inner via hole, 8. telescopic cross bar, 9. connection dish, 10. automatically-controlled door, 11. dirt seal housings, 12. shaft couplings, 13. decelerators.

Detailed description of the invention

Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.

As shown in Figure 1, a kind of projector mount, including base plate 1, the outer bar 2 of suspension bracket, bar 6 in suspension bracket, connection dish 9, controlling organization, telescopic cross bar 8, base plate 1 is fixing on the ceiling, base plate 1 is connected below the outer bar 2 of suspension bracket, the outer bar 2 of suspension bracket arranges controlling organization, controlling organization includes drive motor 3, shaft coupling 12, decelerator 13, decelerator 13 has common line shaft with the outer bar 2 of suspension bracket, suspension bracket is equipped with multiple accessibke porosity 4 on outer bar 2 two side, the outer bar 2 of suspension bracket is internal extends downwardly from bar 6 in suspension bracket, in suspension bracket, bar 6 two side is provided with the inner via hole 7 corresponding with accessibke porosity 4, accessibke porosity 4 and inner via hole 7 are connected by fixed screw 5, in suspension bracket, bar 6 is connected below telescopic cross bar 8, telescopic cross bar 8 is arranged below the connection dish 9 for connecting projector. connection dish 9 is outside is provided with dirt seal housing 11. dirt seal housing 11 is above provided with automatically-controlled door 10.

When the projector changing new model, or during conversion projected position, motor 3 is decelerated to suitable rotational speed through decelerator 13, the outer bar 2 of suspension bracket is driven to rotate to suitable direction, regulate telescopic cross bar 8 to the far and near position being suitable for, and regulate in the outer bar 2 of suspension bracket and suspension bracket the relative position between bar 6, with fixed screw 5, inner via hole 7 and accessibke porosity 4 are connected fixing, it is achieved best drop shadow effect.

Above one embodiment of the present of invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention. All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention.
