Display device for teaching experiments

Abstract

The invention discloses a display device for teaching experiments. The display device comprises a base plate, an adjusting rod, a specimen bottle and a second cleaning block, wherein a display cylinder is movably installed above the base plate, the adjusting rod penetrates through the side wall of the display cylinder, a movable cylinder penetrates through conical teeth, the outer side of a guiderod is sleeved with a valve plate, a specimen bottle is clamped and installed on the upper end face of a supporting plate, the outer side of a fixing hole is connected with the supporting plate through a limiting block, a first spring is wound around the outer side of a movable rod, a baffle is hinged to the top part of a display cylinder, and the bottom part of a second fixing groove is connectedwith a fixing cavity through a connecting channel. According to the display device for the teaching experiments, the specimen bottle can be protected in the display process, a specimen inside the specimen bottle is prevented from being affected by damage of the specimen bottle, light-proof storage of the specimen bottle can be achieved, the storage life of the specimen bottle is prolonged, and meanwhile dust adhering to the surface of the specimen bottle can be removed in the display and storage process.

Description

technical field [0001] The invention relates to the technical field of teaching experiment display, in particular to a display device for teaching experiment. Background technique [0002] The display device for teaching experiments is a device for displaying experimental objects or related equipment during the teaching experiment process. Generally, it is a cabinet or panel storage display structure, which is very common in teaching. Among them, the teaching experiment display The device is most frequently used in the process of chemistry, physics or biology teaching experiments. In the process of biology teaching experiments, because it is impossible to directly display the living animals and plants, biological specimens will be placed in the display device for teachers to teach Use and help students fully understand biology-related knowledge, but the existing display devices for teaching experiments still have the following problems in the actual use process: [0003] 1....

Problems solved by technology

[0002] The display device for teaching experiments is a device for displaying experimental objects or related equipment during the teaching experiment process. Generally, it is a cabinet or panel storage display structure, which is very common in teaching. Among them, the teaching experiment display The device is most frequently used in the process of chemistry, physics or biology teaching experiments. In the process of biology teaching experiments, because it is impossible to directly display the living animals and plants, biological specimens will be placed in the display device for teachers to teach Use and help students fully understand biology-related knowledge, but the existing display devices for teaching experiments still have the following problems in the actual use process:

[0003] 1. After the existing biological experiment specimens are loaded into the specimen bottle, most of them are placed naked indoors and directly in contact with the light source. Since some specimens need to be kept away from light, traditional display devices lack the ability to shield the specimen bottle from light. structure, resulting in damage to specimens during storage;

[0004] 2. In addition, the specimen bottle lacks a structure to protect it during storage and display. When the specimen bottle is impacted, it is very easy to cause damage to the specimen. At the same time, dust will adhere to the surface of the specimen bottle during long-term display or storage, affecting clarity of display
