Background technology
In modern teaching process, projector is a kind of conventional teaching appliance, and it is mostly preloaded in the ceiling of multi-media classroom or is put in the enterprising enforcement use of desk temporarily.Projector is installed in after on ceiling, and because hanging position is higher, therefore it is difficult to maintained, and the dust of long time integration has a strong impact on the serviceable life of projector, causes quality of instruction to decline, increases instruction cost simultaneously; Projector is put in the enterprising enforcement use of desk temporarily, causes it directly to contact with desktop, can not dispel the heat very well, cause the work of projector long-term overheat, affect serviceable life.
Summary of the invention
For overcoming the technological deficiency that existing projector mount is difficult to regulate, the utility model proposes a kind of reasonable in design, projector rack for computer teaching that result of use is good.
For this reason, the technical solution of the utility model is: Multifunctional projector frame, comprises fixed bin, is provided with chute bottom fixed bin, it is characterized in that:
Motor and toggle is provided with in fixed bin inside, motor is vertically arranged on fixed bin side, motor output shaft is connected with toggle one end, the crank connecting link mechanism other end is connected with slide block, the corresponding fixed bin chute of slider bottom is provided with boss, and slide block boss is plugged in fixed bin chute;
Elevating mechanism is provided with in fixed bin outside, described elevating mechanism is formed by joining end to end between two by least one pair of lifting transmission arm, and it is hinged by rotating shaft in the middle of often pair of lifting transmission arm, make upper arm one end of lifting transmission arm be hinged on fixed bin lower end during assembling, the upper arm other end of lifting transmission arm is hinged on slide block boss lower end; Be provided with a rail plate in lifting transmission arm underarm level, the underarm two ends of lifting transmission arm are connected to the two ends, left and right of rail plate; Bottom rail plate, be provided with universal shaft by Connection Block, universal shaft lower end is provided with fixed claw dish.
One for technique scheme is improved and is: for improving the intensity of fixed bin, in institute, fixed bin bottom inside is provided with floor.
Using method:
During use, first projector is fixed on the projector fixed claw dish of projector rack lower end, then the fixed bin of projector rack upper end is fixed by screws on the ceiling of classroom; Start remote controller buttons, driven by motor toggle circles, toggle band movable slider moving linearly in fixed bin chute, slide block drives lifting transmission arm one end rectilinear motion, whole lifting transmission arm is made to do shearing motion in " X " formula structure, changed the height of projector rack by the extension and compression being elevated transmission arm, realize the lifting of projector, control the use height of projector with this; When needs change projector angles, start universal shaft rotary knob, drive projector to rotate by universal shaft and realize its 360 degree rotations.
Beneficial effect:
The utility model is by being connected motor with toggle, be connected with elevating mechanism by toggle again, be the rectilinear motion of crank block by the convert rotational motion of motor, drive elevating mechanism to uphold and compression by slide block again, controlled the use height of projector by the change of its height; Meanwhile, by projector is connected with universal shaft, can rotates within the scope of 360 degree, achieve the change of projector angles.This projector rack structure is simple, reasonable in design, practical, in teaching, the use of projector provides conveniently, ensure that quality of instruction; Meanwhile, sweeping and keeping in repair and provide conveniently for projector, extends its serviceable life, reduces instruction cost.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is toggle structural representation in the utility model;
Number in the figure is: 1, fixed bin; 2, chute; 3, motor; 4, toggle; 5, slide block; 6, transmission arm is elevated; 7, rotating shaft; 8, web joint; 9, rail plate; 10, Connection Block; 11, universal shaft; 12, fixed claw dish; 13, floor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Multifunctional projector frame, comprises fixed bin 1, offers the chute 2 of segment length's bar shaped in the bottom center of fixed bin 1, simultaneously, a motor 3 and a toggle 4 are installed in the inside of fixed bin 1, described toggle 4 is formed by rotating shaft is hinged by two connecting rod head and the tail, during assembling, motor 3 output shaft is upwards vertically placed, and motor lower end is bolted on the left side of fixed bin 1, then the left end of the output shaft of motor 3 and toggle 4 is threaded connection, again the right-hand member of crank connecting link mechanism 4 is bolted to connection a slide block 5, the bottom of described slide block 5 corresponds to fixed bin chute and leaves a boss, during installation, slide block boss to be plugged in fixed bin chute thus slide block 5 can be moved along chute 2, an elevating mechanism is installed in the outside of fixed bin 1, described elevating mechanism to be joined end to end between two by rotating shaft to lifting transmission arm 6 by three and forms, and by middle hinged by rotating shaft 7 for often pair of lifting transmission arm, during assembling, the upper arm left end being elevated transmission arm topmost for a pair is hinged on web joint 8 lower end by rotating shaft, and web joint 8 upper end is welded on the lower end of fixed bin 1, the upper arm right-hand member being elevated transmission arm topmost for a pair is hinged on slide block boss lower end by rotating shaft simultaneously, on the underarm of a pair lifting transmission arm bottom, level installs a rail plate 9, during assembling, the underarm two ends of a pair lifting transmission arm is bottom connected to the two ends, left and right of rail plate 9 respectively by bulb connecting link, be fixedly connected with a Connection Block 10 in the bottom of rail plate 9 by screw, Connection Block 10 connects a universal shaft 11 by a bearing, be bolted to connection a fixed claw dish 12 in the lower end of universal shaft 11, during use, be used for fixing projector.
