Teaching all-in-one machine convenient to adjust and adjusting method thereof

Abstract

The invention discloses a teaching all-in-one machine convenient to adjust and an adjusting method thereof, and relates to the technical field of teaching equipment. The teaching all-in-one machine comprises a movable base. The movable base is connected with two rotating shafts in a rotating mode, and fixed pipes are fixed to the movable base. A lifting pipe is sleeved with each fixed pipe. The lower end of each lifting pipe is connected with a shaft sleeve in a rotating mode. A transmission pipe is connected in each lifting pipe in a rotating mode. The inner wall of each lifting pipe is connected with an adjusting pipe through a telescopic device. A transmission rod is connected between the two lifting pipes in a rotating mode. Latch grooves are arrayed in the upper end face of each shaftsleeve. An end face gear ring is fixed to the upper end face of each transmission pipe. Limiting tooth grooves are arrayed in the lower end face of each transmission pipe. The inner wall of each adjusting pipe is matched with the corresponding rotating shaft. The lifting pipes drive an all-in-one machine body to achieve height adjustment, and the use convenience and adaptability of the all-in-onemachine body are improved; and the transmission pipes drive the transmission rod to rotate, adjustment of the all-in-one machine body in the length-width direction is achieved, the all-in-one machinebody can better display long pictures or files, and the overall display effect is effectively improved.

Problems solved by technology

[0003] However, the height of the existing all-in-one machine cannot be adjusted flexibly, resulting in poor adaptability to application scenarios. At the same time, the screen of the existing all-in-one machine cannot be rotated after installation. When the all-in-one machine displays some long pictures or files, it is affected by The influence of the aspect ratio of the screen of the all-in-one machine can only display a part of the picture or file. If the picture or file is reduced, it will affect the overall display clarity and affect the overall display effect of the all-in-one machine
