[0003] Existing desks are simple in structure and single in function. At present, the desks used by school students are generally provided with an unsealed drawer under the desk, and experimental instruments or learning tools are placed in the drawer. And there is no fixed position, it is inconvenient to find, and because the front is not sealed, during the daily learning process, due to various reasons such as collisions, experimental instruments or learning tools will fall to the ground, resulting in dirt and affecting learning efficiency And it is easy to cause damage to the experimental equipment

Abstract
The invention discloses a folding desk for learning experiments. The folding desk is characterized in that the desk comprises a desk body, a first lead screw and a second lead screw are movably connected to the bottom of the desk body, the outer surface of the first screw rod is fixedly connected with a first rotating wheel, the outer surface of the second screw rod is fixedly connected with a second rotating wheel, the first rotating wheel is engaged with the second rotating wheel through a gear, the first screw rod and the second screw rod are in threaded connection with a lifting platform,a handle is arranged at the end part of the first screw rod, through handle rotation, the handle drives the first screw rod to rotate, the first screw rod drives the first rotating wheel to rotate, the first rotating wheel drives the second rotating wheel to rotate, the second rotating wheel drives the second screw rod to rotate, the first screw rod and the second screw rod respectively drive thelifting platform to ascend so as to take out the experimental instrument, and when an experiment is finished, the experimental instrument is placed into the lifting platform by reversely rotating thehandle, so that the experimental instrument is prevented from being damaged by collision during carrying in a storage process.
Description
technical field [0001] The invention relates to the field of desks, in particular to a folding desk for learning experiments. Background technique [0002] Experiment is a very important part of teaching work. There are special laboratories in the school, and the experimental table is one of the very important equipment in the laboratory. Many experiments must be completed on the experimental table. Therefore, the experimental table Good or bad directly affects the effect of the experiment. [0003] Existing desks are simple in structure and single in function. At present, the desks used by school students are generally provided with an unsealed drawer under the desk, and experimental instruments or learning tools are placed in the drawer. And there is no fixed position, it is inconvenient to find, and because the front is not sealed, during the daily learning process, due to various reasons such as collisions, experimental instruments or learning tools will fall to the gro...
