Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0019] refer to Figure 1-3 , a kind of experimental teaching equipment with a ventilation function, including a test bench 1, the experimental device placed on the top of the test bench 1 is the prior art, and does not involve the innovation points here, so I will not repeat it here, the test bench The top of 1 is symmetrically fixedly connected with a support plate 2, and the tops of the two support plates 2 are fixedly connected with a top plate 3, and a limit hole 4 is opened on the side wall of the top plate 3 near one side, and the limit hole 4 is located on the two support plates 2, the limit hole 4 is inserted with an adjustment plate 5, the fan 6 is installe...

The invention relates to the technical field of teaching equipment, and discloses experimental teaching equipment with a ventilation function, which comprises a test bed, supporting plates are symmetrically and fixedly connected to the top of the test bed, a top plate is jointly and fixedly connected to the tops of the two supporting plates, and a limiting hole is formed in the side wall, close to one side, of the top plate. The limiting hole is located between the two supporting plates, an adjusting plate is inserted into the limiting hole, a fan is installed on the side wall of the bottom, away from the supporting plates, of the adjusting plate, a T-shaped sliding groove is formed in the side wall, away from the fan, of the adjusting plate, clamping grooves are symmetrically formed in the groove bottom of the T-shaped sliding groove, and a T-shaped sliding block is slidably connected into the T-shaped sliding groove; the end, away from the groove bottom of the T-shaped sliding groove, of the T-shaped sliding block penetrates through a groove opening of the T-shaped sliding groove, extends outwards and is fixedly connected with the hole wall of the limiting hole, and a through hole is formed in the T-shaped sliding block. According to the invention, the exhaust of the experiment device is facilitated, and the fan does not occupy the space to hinder the experiment.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an experimental teaching equipment with a ventilation function. Background technique [0002] In the teaching of physics, biology, especially chemistry, it is often necessary to conduct experiments, such as chromosome experiments, chlorophyll extraction experiments, chemical chemical reaction experiments, etc. During these experiments, there will be influential gases, and these gases need to be cleaned up. Cleaning is done by installing a fan, but installing a fan on the test bench will occupy a certain amount of space and affect the progress of the experiment; this only involves the cleaning of the gas generated during the experiment, not the conduct of the experiment, and will not be carried out here for the experimental equipment Let me repeat. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing experi...
