Embodiment 1

[0025] In Embodiment 1, when the device is used, the body 4 is first raised by the push rod motor 5, so that the lens of the body 4 is higher than the housing 1, and the damping hinge 6 makes the body 4 not easy to shake, and then the knob 8 is turned to slow down The machine 7 drives the rotating rod 10 to rotate slowly through the gear 9, and finally the rotating rod 10 drives the stud 13 to rotate through the second telescopic rod 12. Groove 16 drives body 4 to rotate, adjusts the angle of body 4 lens, makes body 4 have better projection effect, and adjustment process is convenient and simple, and the upper end of rotating rod 10 is provided with the chute of rectangular parallelepiped, and the second telescoping rod 12 is rectangular parallelepiped Shape, the rotation rod 10 cooperates with the second telescopic rod 12, can guarantee that the stud 13 can rotate normally, and the distance between the stud 13 and the rotation rod 10 can change simultaneously, guarantees the n...

Embodiment 2

[0026] In Example 2, when the device is stored, the body 4 can be well protected by the casing 1, and the first telescopic rod 3 can buffer the body 4 under the action of elasticity, which avoids the device being damaged during transportation. got damage.

Abstract

The invention discloses a teaching projector capable of being conveniently carried by teachers. The teaching projector comprises a shell. Four fixing rods are welded at the bottom of the inner wall ofthe shell, first telescopic rods are inserted in the upper ends of the fixing rods, a body is arranged at the upper ends of the first telescopic rods, two push rod motors are mounted at the bottom ofthe inner wall of the shell via screws, and the upper ends of the push rod motors are connected with the body by damping hinges. The teaching projector has the advantages that the body can be liftedby the aid of the push rod motors at first when the teaching projector is used, lenses of the body are higher than the shell, the damping hinges can prevent the body from easily shaking, then a knob can rotate, a rotary rod can be driven by a speed reducer via a gear to slowly rotate at the moment, a stud can be ultimately driven by the rotary rod via a second telescopic rod to rotate and can be upwardly or downwardly used under the matching effect of a support, the body can be ultimately driven by a fixture block and a clamp groove to rotate, angles of the lenses of the body can be adjusted,accordingly, good projection effects can be realized by the body, and adjustment procedures are convenient and simple.

Description
