Description

Technical Field

[0001] The utility model relates to the field of experimental teaching, in particular to a combined operating device for experimental teaching. Background Art

[0002] Experimental teaching is an important teaching method. It enhances students' learning experience and improves their ability to understand and apply knowledge by allowing them to personally participate in experimental activities. Experimental teaching is usually used in disciplines such as science, engineering, and medicine. Through teachers' demonstrations, students can further understand and learn knowledge.

[0003] An experimental table is generally used in experimental teaching. When conducting more complicated experiments, many and diverse instruments are required. However, the existing experimental table has a simple structure and single function. In addition, due to its small area, it is impossible to place too many instruments. At the same time, the display direction of the experimental results is generally fixed and needs to be manually adjusted, which is not convenient for students to observe the experimental results. Moreover, when a trash can containing waste is placed at the feet, it is easy to be accidentally kicked over, which poses a certain risk. Therefore, a combined operating device for experimental teaching is proposed to solve the above problems. Utility Model Content

[0026] 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.

[0027] In the embodiment, Figure 1-4A combined operating device for experimental teaching is provided. The utility model includes an experimental table main body 1, and two hydraulic push rods 2 are fixedly connected to the interior of the experimental table main body 1. The tops of the two hydraulic push rods 2 are fixedly connected to the bottom of the first support plate 3, and the bottom of the first support plate 3 is fixedly connected to a motor 4. A first give way groove is provided on the internal top wall of the experimental table main body 1, and a display table 5 slidably connected to the first give way groove is fixedly connected to the outside of the output shaft of the motor 4. A second give way groove is provided on the internal left wall of the experimental table main body 1, and a storage box 6 is slidably connected to the interior of the second give way groove, and the bottom of the storage box 6 is rotatably connected to the second support plate 7. A trash can 8 is provided inside the experimental table main body 1, and a give way hole located above the trash can 8 is provided inside the experimental table main body 1.

[0028] An annular groove is provided inside the first supporting plate 3 , and an annular plate 9 is fixedly connected to the bottom of the display stand 5 and is slidably connected to the annular groove.

[0029] In this embodiment, during actual use, when the motor 4 is started to drive the display stand 5 to rotate, the annular plate 9 will slide inside the first support plate 3 to stabilize the rotation of the display stand 5 .

[0030] Among them, the front and rear walls inside the second give way groove are both provided with sliding grooves, and the front and rear sides of the storage box 6 are fixedly connected with slide plates 10 that are respectively slidably connected to the two sliding grooves.

[0031] In this embodiment, during actual use, the slide plate 10 provides support for the storage box 6. During the process of pulling out the storage box 6, the slide plate 10 slides in the slide groove and prevents the storage box 6 from shaking up and down.

[0032] Among them, two limiting plates 11 are fixedly connected to the inside of the second clearance groove and are symmetrically distributed front to back, and the bottom of the storage box 6 is fixedly connected to baffles 12 corresponding to the two limiting plates 11 respectively.

[0033] In this embodiment, during actual use, after the storage box 6 is pulled out to a certain distance, the baffle 12 below the storage box 6 will be blocked by the limiting plate 11, and the storage box 6 cannot be completely pulled out, thereby preventing the storage box 6 from falling.

[0034] Among them, the two limiting plates 11 are each provided with a limiting hole inside, and the left sides of the two baffles 12 are fixedly connected with a threaded rod 13 that passes through and extends to the outside of the two limiting holes respectively, and the outside of the two threaded rods 13 are threadedly connected with a nut 14.

[0035] In this embodiment, during actual use, when the storage box 6 is pulled out to the farthest distance, the threaded rod 13 on the left side of the two baffles 12 will pass through the two limit plates 11. At this time, the position of the storage box 6 can be fixed by screwing the two nuts 14 and the threaded rod 13 to prevent the storage box 6 from sliding.

[0036] A handle 15 is fixedly connected to the left side of the storage box 6 , a plurality of partition plates 17 are provided inside the storage box 6 , and a plurality of storage cabinets 16 are provided inside the laboratory table body 1 .

[0037] In this embodiment, during actual use, the handle 15 can control the movement of the storage box 6, the partition plate 17 can divide the space of the storage box 6 into areas, and the multiple storage cabinets 16 can place and store experimental instruments.

[0038] Working principle:

[0039] When conducting experimental teaching, the storage box 6 can be first pulled out by the handle 15. A lock can be set on the outside of the storage box 6 to prevent others from touching it by mistake. Then, the storage box 6 is moved to the left until the threaded rod 13 passes through the limit plate 11, and the second support plate 7 under the storage box 6 can be rotated. The second support plate 7 can be adsorbed under the storage box 6 by magnetic attraction by installing a magnet. The second support plate 7 is rotated, and the other end of the second support plate 7 just supports the ground. An adjusting foot can be set at one end of the second support plate 7 for fine adjustment and to prevent the plate from directly contacting the ground. The second support plate 7 will be on the left side of the storage box 6. The side provides support, and the position of the storage box 6 is locked by the nut 14. The nut 14 can be placed in the storage box 6 or the storage cabinet 16. The opening of the storage box 6 faces upward, which is convenient for taking out the experimental equipment. After the experiment, the waste materials can be directly poured into the trash can 8 through the give way hole. The trash can 8 is hidden in the main body of the experimental table 1. The cabinet door can be opened to take it out and replace it without accidentally touching it. During the experiment or after the results are completed, the experimental objects can be placed on the display stand. The hydraulic push rod 2 can be raised by the control panel under the drive of electricity, and the motor 4 can also drive the display stand 5 to rotate to enhance the display effect.
