Specific embodiment

Embodiment:

The utility model is described in further detail below in conjunction with attached drawing.

A kind of administration instructional device, as shown in Figures 1 to 5, including by two crossbeams 11 and two 12 structures of column At frame body 1, the projection plate 13 being used cooperatively with projector is embedded in frame body 1, sliding connects frame body 1 vertically It is connected to horizontally disposed cross bar 2, cross bar 2 further includes driving cross bar 2 along vertical for hanging blackboard 3, administration instructional device Direction is mobile and has the driving device 4 of self-locking function.By the driving device 4 with self-locking function faculty is being needed When converting blackboard 3 and projection plate 13, conversion between the two can be realized automatically by driving device 4, it is more humanized And the experience sense during raising student instruction.

2 both ends end of cross bar is extended with sliding block 21, and two columns 12 are correspondingly arranged on along the vertical direction to be cooperated with sliding block 21 Sliding slot 121, the sliding block 21 at 2 both ends of cross bar is caught in the sliding slot 121 of column 12, cross bar 2 is done along column 12 perpendicular Histogram to movement, while can to avoid there is a situation where 2 one end of cross bar deviate.

Driving device 4 with self-locking function includes the motor 41 that 2 one end of cross bar is arranged in, and is set in the rotation axis of motor 41 There is gear 42, the column 12 positioned at 41 the same side of motor is equipped with the rack gear 43 engaged with gear 42 along the vertical direction.Pass through rotation Motor 41, being engaged of gear 42 and rack gear 43 allows to control cross bar 2 and moves along the vertical direction, while motor 41 stops When rotation, gear 42, which stops operating, enables cross bar 2 to stop at some height, and keeps opposing stationary.

12 upper and lower ends of column for being equipped with gear 42, which are respectively provided with, to be changed 41 rotation direction of motor and makes motor 41 The first stroke switch 122 and second stroke switch 123 of stopping drive cross bar 2 to move upwards when motor 41 rotates, and cross bar 2 is transported When moving 1 upper end of frame body, cross bar 2 contacts first stroke switch 122, so that motor 41 be made to stop operating, cross bar 2 stops fortune It is dynamic；Cross bar 2 is driven to move downward when motor 41 rotates, when cross bar 2 moves to 1 lower end of frame body, cross bar 2 contacts second stroke Switch 123, so that motor 41 is made to stop operating, 2 stop motion of cross bar.First stroke switch 122 and second stroke switch 123 Setting can protect cross bar 2 without departing from frame body 1, and play the role of protecting motor 41.

Gear towards frame middle position and parallel with projection plate 13 is connected on the column 12 of 41 the same side of motor Plate 5.In the present embodiment, fixation is bolted with corresponding column 12 in baffle 5, facilitates the cross bar 2 and rack gear 43 of early period Installation, also facilitate later maintenance when failure.

The accommodating case 51 that multiple tops are opening is equipped on front side of baffle 5, accommodating case 51 is uniformly divided along the vertical direction of baffle 5 Cloth.Some realias can be directly introduced in accommodating case 51, student can be made in viewing administration instructional device When, entire perception is more harmonious, while can also bigizationner utilize entire administration instructional device.The lowermost accommodates 51 outer wall of box is equipped with the control switch 44 for starting the operation of motor 41, and faculty realizes cross bar 2 by control switch 44 Up and down motion, while cooperating first stroke switch 122 and second stroke switch 123 realizes the upper and lower of cross bar 2 in which can be convenient It moves and is automatically stopped.

Working principle:

When faculty needs to convert between blackboard 3 and projection plate 13, the upper of cross bar 2 is realized by control switch 44 Lower movement needs position when cross bar 2 is moved to faculty to quickly realize the conversion between blackboard 3 and projection plate 13 When place, faculty can be by unclamping the stationary state contacted to realize cross bar 2 to control switch 44, while faculty It can also be made between cross bar 2 by first stroke switch 122 and second stroke switch 123 at the end of the upper and lower ends of column 12 Automatically stopping is realized in portion position.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
