[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment: A chemical experiment rack, such as Figure 1-Figure 3 As shown, it includes a base 1, a support frame 2, the support frame 2 is fixed to the base 1, and a height-adjustable clamp is provided on the support frame 2. It also includes a shell 3 and a storage rack 4. The shell 3 is connected to the base 1. The shell 3 and the base 1 are slidably connected by a spline, which facilitates the separation of the base 1 and the shell 3 for transportation. The storage rack 4 is symmetrically arranged and rotatably connected to the side of the shell 3 by a hinge. The bolt 6 is slidably connected to the shell 3. The bolt 6 can be slidably inserted into the storage rack 4 to limit and fix it. The storage rack 4 can form a closed space with the shell 3.
