Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 10, the present invention provides a technical solution: a high school student chemical experiment table comprises a bottom box 1, two tables 2 and two fixed blocks 3, wherein the two fixed blocks 3 are respectively corresponding to the outer sides of the tables 2, a fixed shaft 4 penetrates through one end part of each table 2, the end part of each fixed shaft 4 is fixedly connected with the inner side of each fixed block 3, a roller 5 is fixedly arranged on the inner side, close to the top part of each table 1, of each bottom box, a baffle 6 is fixedly connected with the other end part of each table 2, a communicated rolling groove 7 is formed in the end surfaces of the corresponding table 2 and the baffle 6, the inner wall of each rolling groove 7 is in rolling connection with the outer wall of each roller 5, the rollers 5 and the rolling grooves 7 are matched to form a rolling effect, so that the tables 2 are more labor-saving in the unfolding or folding process, a threaded rod 8 is fixedly connected to the surface of each fixed block 3, a through groove 9 is formed in the end surface of each bottom box, the first handle 10 is used for locking and fixing the position of the fixing block 3 at the inner side of the through groove 9, so that the bedplate 2 is prevented from sinking into the bottom box 1 in the unfolded state on one hand, and the bedplate 2 is prevented from sliding out due to the fact that the bottom box 1 is turned upside down in the folded and carried state on the other hand.
