Abstract

The invention discloses a platform lifter special for a lab platform, which comprises a top plate (1), a lifting plate (2) and a mounting frame (3). An upper protective sleeve (4) and a lower protective sleeve (5) which are coaxial are arranged on the lower side of an upper wall and the upper side of a lower wall of the mounting frame (3) respectively, each of the upper protective sleeve (4) and the lower protective sleeve (5) is provided with an internal nut (6) movably connected with the upper protective sleeve (4) or lower protective sleeve (5), a screw (7) meshed with the nuts (6) is arranged in the nuts (6), the upper end of the screw (7) vertically penetrates through the nuts (6) to be connected with the lifting plate (2), a driven wheel (8) fixedly connected with the nuts (6) is sleeved outside the nuts (6), a drive wheel (9) meshed with the driven wheel (8) is arranged on one side of the driven wheel (8) and fixed on a drive shaft (10), one end of the drive shaft (10) is movably connected to the lateral wall of the mounting frame (3), and the other end of the drive shaft (10) horizontally penetrates through the mounting frame (3) to be connected with a crank (11). The platform lifter special for the lab platform is high in practicality and wide in application range.

Description

technical field [0001] The invention relates to a laboratory platform, in particular to a platform used by teachers in a laboratory for performing experimental demonstrations, in particular to a special platform lifter for a laboratory platform. Background technique [0002] When doing experiments in the existing laboratory, the teacher and the students use the same specification of the experimental table. When the teacher is doing the experiment demonstration, many students cannot see clearly the teacher's demonstration action or some problems that appear during the experiment due to the obstruction of the line of sight. This feature makes this part of the students have to watch around the experimental table used by the teacher, so that they cannot do the experiment or the evolution process of the experiment synchronously, and may also affect the teaching order during the experiment. For example, when the teacher demonstrates the acid-base neutralization experiment, the aci...
