Abstract
The utility model relates to a curtain, and especially relates to a rapid lifting curtain of a multi-media classroom. The rapid lifting curtain of the multi-media classroom comprises a classroom blackboard and a curtain arranged in front of the classroom blackboard. The rapid lifting curtain of the multi-media classroom is characterized in that the curtain is arranged on a lifting air cylinder, the bottom part of the lifting air cylinder is connected with an air inlet and outlet pipe, and the end part of the air inlet and outlet pipe is connected with an air compressor. The rapid lifting curtain of the multi-media classroom has the advantages that the curtain can be rapidly ascended and descended, thereby enabling rapid conversion of a teacher between a multi-media teaching mode and a conventional teaching mode; and the rapid lifting curtain of the multi-media classroom is simple in structure and convenient to operate, the time is saved, and the teaching efficiency is improved.
Description
(1) technical field
The utility model relates to a kind of curtain, particularly a kind of multi-media classroom fast lifting curtain.
(2) background technology
School's multi-media classroom generally has the setting of two form of teachings: when needs are used projector, handle curtain and fall, the teacher opens computer and implements the multimedia mode teaching; But the course of going up is not used multimedia needs sometimes, the teacher does not use projector, implements the traditional approach teaching but add to tell about with the blackboard writing on the blackboard.For both take into account, the multi-media classroom front is all to hang blackboard, and the curtain volume rises more than blackboard.When without projector, the teacher uses blackboard directly to attend class; And class hour on the use projector falls curtain, open projector and computer, these operations uncomplicated.No matter use separately which kind of form of teaching, concerning Faculty and Students all without inconvenience.
But some courses are used projector to implement teaching, and teacher also will write some words or the open-and-shut diagram of graphical pointv with blackboard in the middle of teaching, and is explained.For the needs of this mode of attending class, one side just at the blackboard that sets up at dais, for the interim writing on the blackboard of teacher.The teacher who attends class so generally utilizes multimedia to attend class at the opposite side of interim blackboard, in the time of need to writing, stands up to move towards blackboard.Sometimes teacher's writing on the blackboard adds explanation when more, and the student obtains the amesiality teacher of seeing of rotary head and teaches, and there will be so tired.
, in the multi-media classroom of pattern, rise curtain if when the teacher who requires above two kinds of modes to attend class transfers the conventional teaching pattern to by multimedia, turn off projector now, curtain rises can be very slow, can have a strong impact on like this carrying out continuously of teaching.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, while using, rise the multi-media classroom fast lifting curtain that used time not falls.
The utility model is achieved by the following technical solution:
A kind of multi-media classroom fast lifting curtain, comprise classroom blackboard and the curtain that is arranged at the classroom blackboard front, it is characterized in that: described curtain is installed on the lifting reservoir, and lifting reservoir bottom is connected with the air intake-exhaust pipe, and air intake-exhaust pipe end is connected with air compressor.
Described lifting reservoir bottom is located on mounting-fixing base, and air intake-exhaust pipe front end is fixed on mounting-fixing base.
Between described air intake-exhaust pipe end and air compressor, be provided with air reservoir.
Described lifting reservoir is comprised of three grades of cover cylinders, is followed successively by from down to up one-level reservoir, secondary reservoir and force 3 wind cylinder.
The beneficial effects of the utility model are: can rise fast and fall curtain, being convenient to teacher's conversion fast between multimedia and conventional teaching pattern; Simple in structure, easy to operate, saved the time, improved efficiency of teaching.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
View when accompanying drawing 1 is curtain rise of the present utility model;
View when accompanying drawing 2 is fallen for curtain of the present utility model;
In figure, 1 classroom blackboard, 2 curtains, 3 lifting reservoirs, 4 air intake-exhaust pipes, 5 air compressor, 6 mounting-fixing bases, 7 air reservoirs, 8 one-level reservoirs, 9 secondary reservoirs, 10 force 3 wind cylinders.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises classroom blackboard 1 and the curtain 2 that is arranged at classroom blackboard 1 front, and curtain 2 is installed on lifting reservoir 3, and lifting reservoir 3 bottoms are connected with air intake-exhaust pipe 4, and air intake-exhaust pipe 4 ends are connected with air compressor 5.Lifting reservoir 3 bottoms are located on mounting-fixing base 6, and air intake-exhaust pipe 4 front ends are fixed on mounting-fixing base 6.Between air intake-exhaust pipe 4 ends and air compressor 5, be provided with air reservoir 7.Lifting reservoir 3 is comprised of three grades of cover cylinders, is followed successively by from down to up one-level reservoir 8, secondary reservoir 9 and force 3 wind cylinder 10.
Adopt multi-media classroom fast lifting curtain of the present utility model, curtain 2 drives successively from bottom to top and rises and even up at one-level reservoir 8, secondary reservoir 9 and the force 3 wind cylinder 10 of lifting reservoir 3, cover traditional classroom blackboard 1, lifting reservoir 3 bottoms have mounting-fixing base 6 that curtain 2 is fixing, air intake-exhaust pipe 4 is fixed on mounting-fixing base 6, draws outside classroom.Air compressor 5 is arranged on the place away from classroom, to reduce the noise in classroom, does not affect teaching.When to need curtain 2 liftings be not too many, machine a little while left by air compressor 5, by compressed-air-storing to standby getting final product in air reservoir 7.Air compressor 5 is grasped switch by the teacher of multi-media classroom.
