Description
Technical field
The utility model relates to multi-media classroom articles for use, especially multimedia teaching curtain suspension arrangement.
Background technology
Along with the development of science and technology, increasing educational institution is equipped with multi-media classroom, and especially a large amount of employs projecting apparatus, and use during projecting apparatus and need with the use of curtain, the storage of curtain and operative installations all occupy certain space.Publication number is that the utility model of CN 203905542U discloses a kind of curtain suspension arrangement, direct use dais stores and hangs curtain, there is certain effect, but still have the following disadvantages: 1, single unit system is all manual operation, waste of manpower and instructional blocks of time; 2, hanging curtain between elevating lever, therefore the height of curtain and width all receive and greatly restrict; 3, curtain hangs only by gravity, not by tension force, makes the curtain of soft material there is fold unavoidably, affects projection quality.
Summary of the invention
Technical assignment of the present utility model is a kind of multimedia teaching curtain suspension arrangement provided for above the deficiencies in the prior art.
A kind of multimedia teaching curtain suspension arrangement, comprise dais, wherein, be respectively equipped with chute in the left and right sides, described dais, in the chute of described left side, be provided with left elevating lever, right elevating lever is provided with in the chute of described right side, described left elevating lever and right elevating lever are connected with transmission device, and described transmission device is connected with motor, and described transmission device is also connected with control panel, described motor and transmission device are all positioned at dais, and described control panel is positioned at above dais.
Described left elevating lever and right elevating lever are square pole, and the mating surface of described left elevating lever and right elevating lever and transmission device is straight-tooth wheel face.
Groove is provided with in the outside of described left elevating lever and right elevating lever, upper pendulum bar is provided with on described each groove top, draft link is provided with in described each groove bottom, described upper pendulum bar and draft link are connected with left elevating lever and right elevating lever by bearing pin, described bearing pin is provided with jump ring, described upper pendulum bar and draft link are respectively equipped with positioner and curtain fixture.
Described upper pendulum bar and draft link are expansion link.
The utility model has the advantage of: 1, control the lifting of elevating lever motorized by control panel, comprise the independent lifting of two elevating lever synchronization liftings and each elevating lever, realize the motorized of curtain lifting and tilt adjustments, save manpower and instructional blocks of time; 2, elevating lever is provided with telescopic fork, goes for the curtain of different size; 3, fork by curtain tensioning, can avoid curtain fold by jump ring, softer curtain can be used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place partial sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As shown in Figure 1 and Figure 2, a kind of multimedia teaching curtain suspension arrangement, comprise dais 1, wherein, chute 9 is respectively equipped with in the left and right sides, described dais 1, left elevating lever 8 is provided with in described left side chute 9, right elevating lever 6 is provided with in described right side chute 9, described left elevating lever 8 and right elevating lever 6 are connected with transmission device 10, described transmission device 10 is connected with motor 11, described transmission device 10 is also connected with control panel 2, and described motor 11 and transmission device 10 are all positioned at dais 1, and described control panel 2 is positioned at above dais 1.Described left elevating lever 8 and right elevating lever 6 are square pole, and described left elevating lever 8 and right elevating lever 6 are straight-tooth wheel face with the mating surface of transmission device 10.Groove 14 is provided with in the outside of described left elevating lever 8 and right elevating lever 6, upper pendulum bar 7 is provided with on described each groove 14 top, draft link 5 is provided with in described each groove 14 bottom, described upper pendulum bar 7 and draft link 5 are connected with left elevating lever 8 and right elevating lever 6 by bearing pin 12, described bearing pin 12 is provided with jump ring 13, described upper pendulum bar 7 and draft link 5 are respectively equipped with positioner 4 and curtain fixture 3.Described upper pendulum bar 7 and draft link 5 are expansion link.
Its operation principle is: when this device does not use, and upper pendulum bar 7 and draft link 5 are stuck in groove 14, and clamps location by positioner 4.During use, control panel 2 controls transmission device 10 and elevating lever synchronously rises by motor 11.Take out upper pendulum bar 7 and draft link 5 from groove 14, now, upper pendulum bar 7 and draft link 5 open by the effect of jump ring 13, thus realize curtain suspension.Meanwhile, control panel 2 can also control arbitrary elevating lever and be elevated separately, for regulating inclination curtain.When the size that upper pendulum bar 7 and draft link 5 open still do not meet curtain use size time, can flexible by upper pendulum bar 7 and draft link 5, adjust opening dimension further, realize the expansion coordinating the curtain size scope of application.
