Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental teaching technology, specifically to an experimental device for assisting learning. Background Technology
[0002] Experimental equipment refers to the instruments and tools required for experiments. In the laboratory, experimental equipment needs to be clamped, and currently, manual clamping is commonly used. Only experimental equipment that requires heating, such as test tubes, is clamped using clips. However, larger experimental equipment such as beakers and flasks are difficult to handle or move manually during heating. Furthermore, students or lab technicians may not wear sterile gloves during the learning process, which can easily contaminate the experimental equipment when handling it.
[0003] In view of this, there is an urgent need to design an experimental apparatus to assist learning. A first clamping ring is fitted onto the outer diameter surface of the experimental apparatus. Pushing the telescopic rod causes a fixed friction ring to fit onto the outer wall of the experimental apparatus. The fixed friction ring generates friction with the outer wall of the experimental apparatus, effectively clamping and fixing the apparatus in place. This enhances the ease of use of the experimental apparatus and prevents contamination. Utility Model Content

The top surface of the beam body 21 is rotatably connected to both sides of the bottom surface of the propulsion structure 5, and the bottom of the beam body 21 is rotatably connected to the top surface of the sliding block 22. The sliding block 22 is slidably connected in the sliding groove 13.
[0017] In this embodiment, the fixed friction ring 4 includes a rubber friction ring 41 and a sleeve seat 42. The two ends of the rubber friction ring 41 are equipped with sleeve seats 42, and the sleeve seats 42 are slidably connected to the outer diameter surface of the inner sliding beam 3.

[0019] Working principle:
[0020] First, a first clamping ring 1 is provided, which is composed of a ring body 11, a rubber inner ring 12, and a sliding groove 13. In use, the ring body 11 is fitted onto the outer wall of the experimental apparatus, and the rubber inner ring 12 is used to enhance the friction between the experimental apparatus and the first clamping ring 1.
[0021] The outer fixed beam 2 is slidably connected in the sliding groove 13 of the first clamp. The outer fixed beam 2 is composed of a beam body 21 and a sliding block 22. The beam body 21 changes its included angle as the sliding block 22 moves along the sliding groove 13.
[0022] The propulsion structure 5 consists of a propulsion seat 51, a propulsion pin 52, and a base 53. The propulsion seat 51 is rotatably connected to the beam 21, while the propulsion pin 52 is slidably connected to the center of the propulsion seat 51. The base 53 is fixedly installed on the bottom surface of the propulsion pin 52. As the propulsion pin 52 advances vertically, the fixed friction ring 4 gradually engages with the outer diameter surface of the experimental apparatus.
[0023] The fixed friction ring 4 is composed of a rubber friction ring 41 and a sleeve seat 42. The rubber friction ring 41 enhances the friction with the experimental equipment, thereby fixing the fixed friction ring 4 to the experimental equipment. The sleeve seat 42 can move along the outer fixed beam 2.
[0024] This invention provides an experimental apparatus for assisting learning. A first clamping ring 1 is fitted onto the outer diameter surface of the experimental apparatus. Pushing the telescopic rod causes a fixed friction ring 4 to fit onto the outer wall surface of the experimental apparatus. The fixed friction ring 4 generates friction with the outer wall surface of the experimental apparatus, effectively clamping and fixing the apparatus. This enhances the ease of use of the experimental apparatus and prevents contamination.
