Description

A kind of electronic tutor based on radio communication
Technical field:
This utility model is related to a kind of electronic tutor based on radio communication.
Background technology:
The existing electronic tutor based on radio communication is combined together using computer and projector and is completed, Computer is placed on teaching desk, can be moved at any time when needing, and using more convenient, projector is hung in nothing on the ceiling in classroom Method is moved, cannot be rotated, and as projector cannot be moved, cannot be rotated, causes computer also move, in-convenience in use, It is dumb.
The content of the invention:
The purpose of this utility model is to provide a kind of projector and lifts convenient, adjustable angle, matches somebody with somebody with computer, projection screen Close a kind of good electronic tutor based on radio communication of using effect.
Above-mentioned purpose is realized by following technical scheme:
A kind of electronic tutor based on radio communication, its composition include:Electronic tutor, described electronics religion Learning device includes computer, projector, projection screen, described projector connection supporting linkage, described supporting linkage Hollow ball in connection, described interior hollow ball load in the bulbus cordis of outer space, and described outer space bulbus cordis includes episphere and lower semisphere, institute The episphere connection inner screw sheath stated, described lower semisphere connection external thread sleeve, the described outer spiral shell of described inner screw sheath connection Stricture of vagina set, described lower semisphere are provided with circular hole, and described supporting linkage passes through described circular hole, described episphere connection lifting Device, has positioner between described episphere and described interior hollow ball.
A kind of described electronic tutor based on radio communication, is provided with one group of jack at the top of described episphere, Described positioner includes flexibly positioned inserted link, and the top of described interior hollow ball connects described flexibly positioned inserted link, institute The jack positioning described in flexibly positioned inserted link insertion described in when the interior hollow ball stated is rotated;Described computer connection teaching Table, described projection screen connection spool, described spool connection classroom body of wall.
A kind of described electronic tutor based on radio communication, described lowering or hoisting gear include top board, described top Plate is connected on the ceiling of classroom, and described top board connects left connection board and right connection board, described left connection board and the described right side Connected by transverse axis between connecting plate, described transverse axis connection upper sprocket wheel, described upper sprocket wheel connection chain, described chain connect Lower sprocket is connect, described lower sprocket connection connecting plate, described connecting plate connect L-shaped axle, and described L-shaped axle connects described Episphere.
Beneficial effect:
1. this utility model is adopted supporting linkage, circular hole make interior hollow ball rotation side in the outer hollow ball Just, it is very convenient during the projector adjustment angle of drive.
The inner screw sheath that this utility model is adopted is used cooperatively with external thread sleeve, can be made between episphere and lower semisphere It is easy to connect, it is also convenient for when loading interior hollow ball, it is good using flexible, effect.
The flexibly positioned inserted link that this utility model is adopted is used cooperatively with jack, can give interior hollow ball and outer space bulbus cordis it Between accurately positioned when mutually rotating, adjustment projector is convenient, flexibly, and using effect is good.
The top board of this utility model employing, left connection board, right connection board, transverse axis, upper sprocket wheel, chain, lower sprocket, connecting plate Use cooperatively, i.e., projector can be firmly fixed on the ceiling of classroom, the height for adjusting projector is also convenient for, convenient and meter Calculation machine, projection screen are good with the use of effect.
Description of the drawings:
Accompanying drawing 1 is the structural representation of this product.
