Height-adjustable vertical education machine

Abstract

The invention discloses a height-adjustable vertical education machine. The education machine comprises a supporting frame, an operation panel, a lifting device, a controller and a power module. The operation panel is fixedly connected with the upper portion of the supporting frame through a connecting support. The lifting device is arranged on the supporting frame. The lifting device comprises a base. A driving motor is fixedly arranged on the base. An output shaft of the driving motor is connected with a driving worm. The driving worm is engaged with a worm gear. The worm gear and a first cylindrical gear are in key connection to conduct driving. The worm gear and the first cylindrical gear are rotatably fixed to a center shaft. The center shaft is perpendicularly fixed to the upper surface of the base. The first cylindrical gear is arranged under the worm gear. A second cylindrical gear is engaged and connected with the first cylindrical gear. The height of the supporting frame can be adjusted through up-down movement of the lifting device. Accordingly, the height-adjustable vertical education machine provided by the invention can be used by users of different heights, and is convenient to adjust and easy to operate.

Problems solved by technology

[0003] In the prior art, the height of the traditional education machine is generally fixed, and the height cannot be adjusted for students at different stages, which brings certain discomfort to the education work and inconvenience to the education and learning of teachers and students.

There are also height-adjustable educational machines in the prior art, but usually a lifting device is composed of a push-pull rod, a push-pull plate and a drive shaft. This lifting device in the prior art has defects. The height of the adjustment is also different. Repeated use of this lifting device will cause wear and damage to the push-pull rod and push-pull plate, and the disassembly and maintenance of the push-pull rod and push-pull plate will waste a certain amount of time. The most important thing is the push-pull rod. The lifting device composed of push-pull plate does not have high adjustment accuracy for the lifting height

[0004] In addition, in the prior art, traditional educational machines usually use guide wheels to enable the educational machine to move in any direction, but when it needs to be fixed, it is often impossible to ensure that the educational machine remains still as a whole, and it is impossible to fix the educational machine in the desired position for a long time.
