Abstract
A kind of projecting apparatus expansion bracket, including the supporting block being fixed on above ceiling, motor is fixed at the top of supporting block, the output axis connection transmission shaft of fixed motor, fixed idler whell on transmission shaft;Loop bar on the ceiling below idler wheel is set, telescopic dynamic loop bar is provided in loop bar, projecting apparatus is fixed in the lower end of telescopic dynamic loop bar;The lower end of telescopic dynamic loop bar is connected on idler wheel around steel wire rope;In use, the rotation of motor driving idler wheel, makes the wirerope-winding on idler wheel, so as to pull the flexible of telescopic dynamic loop bar, and then the flexible of projecting apparatus is driven;The utility model has the advantages of simple in structure, at low cost.
Description
Technical field
The utility model is related to a kind of expansion brackets, and in particular to a kind of projecting apparatus expansion bracket.
Background technology
Projecting apparatus is also known as projector, is a kind of equipment that can be projected image or video on curtain, is widely used in house
Front yard, office, school and public place of entertainment etc..Current most of projector mounts be all it is fixed, problem be i.e. unsightly and
Without causing the trouble such as some block visions during projecting apparatus.
Invention content
Above-mentioned existing in order to overcome the problems, such as, the purpose of this utility model is to provide a kind of projecting apparatus expansion brackets, realize
The automatic telescopic positioning of projecting apparatus, and it is simple in structure, it is at low cost.
In order to achieve the above object, the technical scheme adopted by the utility model is that:
A kind of projecting apparatus expansion bracket, the supporting block 14 including being fixed on 5 top of ceiling, electricity is fixed at the top of supporting block 14
Machine 8, the output axis connection transmission shaft 9 of motor 8, fixed idler whell 11 on transmission shaft 9;Set is set on the ceiling 5 of 11 lower section of idler wheel
Bar 6, telescopic dynamic loop bar is provided in loop bar 6, and projecting apparatus 1 is fixed in the lower end of telescopic dynamic loop bar;Around steel on idler wheel 11
Cord 12 connects the lower end of telescopic dynamic loop bar.
Further, the telescopic dynamic loop bar includes dynamic loop bar 1, and loop bar 1 is nested in loop bar 6, moves set
Bar 1 is nested with dynamic loop bar 23, and dynamic loop bar 23 is nested with dynamic loop bar 32.
Further, the transmission shaft 9 is supported by positioning seat 10, and 10 bottom of positioning seat is fixed on ceiling 5.
The beneficial effects of the utility model:
The utility model drives the rotation of idler wheel 11 by motor 8, winds the steel wire rope 12 on idler wheel 11, so as to pull
Telescopic dynamic loop bar stretches, and then drives the flexible of projecting apparatus 1, has the characteristics of simple in structure, at low cost.
Description of the drawings
Fig. 1 is the structural front view of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of projecting apparatus expansion bracket including ceiling 5, is fixed with loop bar 6 on ceiling 5, supporting block 14 is solid
Due to ceiling 5, for fixing motor 8 and control panel 7, positioning seat 10 is used to positioning and supporting transmission shaft with positioning seat 13
9 position, idler wheel 11 are connected on transmission shaft 9, and for lay winding wire ropes 12, steel wire rope 12 is connected to idler wheel 11 and dynamic loop bar three
2, transmission shaft 9 connect to be driven with motor 8, and dynamic loop bar 1 is nested in loop bar 6, and dynamic loop bar 23 is nested in dynamic loop bar 1,
Dynamic loop bar 32 is nested in dynamic loop bar 23, and dynamic loop bar 32 is connect with projecting apparatus 1.
The operation principle of the utility model is:
When starting projecting apparatus 1, while by the way that motor 8 is controlled to invert, unclasp the steel wire rope being wrapped on idler wheel 11 12,
Due to the gravity of projecting apparatus 1 so that dynamic loop bar 1, dynamic loop bar 23, dynamic loop bar 32 glide, when 1 downslide preset height of projecting apparatus
When, motor 8 is stopped.
When stopping using projecting apparatus 1, control motor 8 rotates forward, and steel wire rope 12 is made to be wound on idler wheel 11, pulls dynamic loop bar
32 so that dynamic loop bar 1, dynamic loop bar 23, dynamic loop bar 32 rise, and after reaching setting position, stop motor 8 and rotate.
