Abstract
The utility model provides a suspension-type English teaching multimedia telescoping screen, and relates to a screen. At present, debugging of a projector belongs to adjustment on a light source position, and scale is not easy to grasp. The suspension-type English teaching multimedia telescoping screen comprises a projection screen and a lead screw mechanism. The projection screen is installed on a reel. Gaps on two edges of the reel are installed with sleeves. An upper end of the sleeve is provided with a lantern ring. The lantern ring is hinged on a nut of a lead screw nut transmission mechanism. A rear end of the lead screw of the lead screw nut transmission mechanism is fixed on a sliding sleeve. The sliding sleeve is sleeved on a fixed rod. An axial direction of the fixed rod is vertical to an axial direction of the lead screw. The sliding sleeve and the fixed rod can just realize axial movement. The telescoping screen can conveniently realize left-and-right movement and front-and-back movement of the projector. When projection position of the projector is not corresponding, the screen can be adjusted left and right. When projection area is not corresponding, the screen can be moved front and back. The screen is simple in structure, and very convenient in use and operation.
Description
Technical field
The utility model relates to a kind of teaching multimedia screen.
Background technology
Mostly undergraduate the English class is to complete by multimedia teaching, by projector, courseware is got on screen and replaced blackboard to impart knowledge to students.Projector is facing to screen prjection while debugging, and often occurs that displaying contents is greater than or less than screen or departs from the situation of screen, needs professional to debug.Debugging for projector now belongs in the adjustment of light source place, is not easy very much to hold yardstick, especially more difficult when needs are finely tuned, and takies the class period, affects the effect of attending class.
Summary of the invention
The purpose of this utility model is to provide the flexible screen of a kind of multimedia, can carry out left and right, seesaw, and very convenient and position projector aligns.
Described object is achieved by the following scheme:
The suspension type English teaching multimedia screen that stretches, comprises projection screen, and described projection screen is arranged on spool, two marginal gap installing sleeves of described spool, and described sleeve upper end arranges the collar; Also comprise screw mechanism, the described collar is hinged on the nut of screw nut driven mechanism, the leading screw rear end of described screw nut driven mechanism is fixed on sliding sleeve, and described sliding sleeve is socketed on fixed bar, described fixed bar axially and leading screw axially in vertical state; Between described sliding sleeve and fixed bar, can only realize axially-movable, concrete structure is: the outside surface of described fixed bar is provided with axial boss, described sliding sleeve inside surface is provided with the groove matching with axial boss, and described sliding sleeve is connected the relative motion realizing between itself and fixed bar with motor.
Described axial boss is 1-4.
The length of described fixed bar is through the width in classroom.
The utility model can conveniently realize projector left and right, seesaw, when projector projected position is not at once, can adjust screen in left and right; When projected area is excessive, moving screen, when projected area is too small, can move forward screen backward.Because moving screen is away from light source point operation, therefore can realize fine setting effect, improve the accuracy aligning.The utility model is simple in structure, uses and operates all very conveniently, is beneficial to and applies.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the syndeton schematic diagram of sliding sleeve and fixed bar.
Wherein, 1-projection screen, 2-sleeve, the 3-collar, 4-nut, 5-leading screw, 6-sliding sleeve, 7-fixed bar.
Embodiment
Below in conjunction with accompanying drawing, elaborate the utility model preferred embodiment.
The suspension type English teaching multimedia screen that stretches, comprises projection screen, sees figures.1.and.2, and described projection screen is arranged on spool, two marginal gap installing sleeves of described spool, and described sleeve upper end arranges the collar;
Also comprise screw mechanism, the described collar is hinged on the nut of screw nut driven mechanism, the leading screw rear end of described screw nut driven mechanism is fixed on sliding sleeve, described sliding sleeve is socketed on fixed bar, described fixed bar axially with leading screw axial in vertical state and the axially parallel of leading screw in ground, the length of described fixed bar is through the width in classroom;
Between described sliding sleeve and fixed bar, can only realize axially-movable, with reference to Fig. 3, concrete structure is: the outside surface of described fixed bar is provided with 1-4 axial boss, described sliding sleeve inside surface is provided with the groove matching with axial boss, and described sliding sleeve is connected the relative motion realizing between itself and fixed bar with motor.
During work, by Electric Machine Control, slide over and on fixed bar, realize axially-movable, the i.e. particular location of capable of regulating screen on the Width of classroom.Because the collar is arranged on the nut of screw nut driven mechanism, when leading screw drives nut to move, can drive screen
Present embodiment does not just limit its protection domain to the exemplary illustration of this patent; those skilled in the art can also carry out part to it and change; as long as no the Spirit Essence that exceeds this patent, be all considered as the replacement that is equal to this patent, all within the protection domain of this patent.
