Description

Technical Field

[0001] The utility model relates to the technical field of stirring paddles, in particular to a stirring paddle for a laboratory narrow-necked reaction bottle. Background Art

[0002] The stirring paddle for narrow-necked reaction flasks is a stirring device specially designed for narrow-necked reaction flasks. Its unique structure enables it to adapt to this special reaction vessel. The stirring paddle generates fluid power through rotation, effectively mixing the substances in the flask to ensure a uniform and efficient reaction process. Due to the limitation of the narrow neck, the design of the stirring paddle needs to take special consideration of its size and shape to ensure that it can enter smoothly and fully play its role. For reactions or microbial growth processes that require oxygen, the stirring paddle can increase the solubility of oxygen in the reaction liquid, improve the efficiency of oxygen transfer, and ensure sufficient oxygen supply during the reaction or growth process. In addition, the stirring paddle for narrow-necked reaction flasks must also have good durability and stability to cope with long-term, high-intensity use. In experiments and research in the fields of chemistry and biology, this stirring paddle plays a vital role, providing scientific researchers with a convenient and efficient tool.

[0003] At present, the stirring paddle used for narrow-necked reaction flasks is restricted by the narrow neck, so that the design and size of the stirring paddle are often limited, resulting in a small contact area between the stirring blade and the reaction flask. The stirring blade may not fully cover the entire internal space of the reaction flask, resulting in uneven mixing of materials, affecting the reaction efficiency and product quality, and failing to achieve the expected stirring effect. Therefore, a stirring paddle for laboratory narrow-necked reaction flasks is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a stirring paddle for a laboratory narrow-necked reaction flask, which has the advantages of increasing the contact area between the stirring blade and the liquid inside the reaction flask, and solves the problem that the stirring blade may not be able to fully cover the entire internal space of the reaction flask, resulting in uneven mixing of materials, affecting the reaction efficiency and product quality, and failing to achieve the expected stirring effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stirring paddle for a laboratory narrow-necked reaction bottle, comprising a top plate, a driving motor and a rotating shaft, wherein an adjustment mechanism is provided at the bottom of the top plate;

[0006] The adjustment mechanism includes an adjustment cylinder fixedly installed on the outer circumferential wall of the rotating shaft, two mounting seats are fixedly installed on the outer circumferential wall of the adjustment cylinder, two adjustment seats are slidably connected to the outer circumferential wall of the adjustment cylinder, limiting sliding rods are fixedly installed on the outer walls on opposite sides of the two adjustment seats, a memory metal stirring blade is fixedly installed on the bottom of the adjustment seat, two limiting seats are fixedly installed on the outer circumferential wall of the adjustment cylinder, two guide plates are fixedly installed on the outer circumferential wall of the adjustment cylinder, and the mounting seat is threadedly connected with a threaded rod.

[0007] Furthermore, the outer wall of the rotating shaft is provided with two "T"-shaped slide grooves, the interior of the adjusting cylinder is provided with two adjustment grooves, the limiting slide rod is slidably connected inside the "T"-shaped slide groove and the adjustment groove and has a matching size, and the limiting slide rod is in a "T" shape.

[0009] Furthermore, a limiting hole is provided inside the limiting seat, and the memory metal stirring blade is slidably connected inside the limiting hole and is adapted in size.

[0010] Furthermore, the guide plate is installed at an inclined angle, and the maximum angle between the guide plate and the adjusting cylinder is 120 degrees.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The stirring paddle for the narrow-necked reaction bottle in the laboratory drives the adjustment seat to move downward to adjust the height through the action of the threaded rod and the mounting seat. Through the action of the memory metal stirring blade body, the memory metal stirring blade moves downward and contacts with the guide plate, causing it to tilt away from the adjustment cylinder and adjust a certain angle, thereby increasing the contact area between the memory metal stirring blade and the liquid inside the reaction bottle, thereby improving the effect of stirring the liquid inside the reaction bottle and making the liquid mixing more uniform.

[0023] Two guide plates 10 are fixedly installed on the outer peripheral wall of the adjusting cylinder 4. The guide plates 10 are installed at an inclined angle. The maximum angle between the guide plates 10 and the adjusting cylinder 4 is 120 degrees. The threaded connection of the mounting seat 5 is provided with a threaded rod 11. The adjusting seat 6 is fitted on the bottom of the mounting seat 5. Two through holes are opened on the top of the top plate 1. There are two threaded rods 11. The threaded rod 11 is rotatably connected to the inside of the through hole. A threaded hole is opened inside the mounting seat 5. The threaded rod 11 is threadedly connected to the inside of the threaded hole and the size is adapted. The threaded rod 11 is rotatably connected to the top of the adjusting seat 6.

[0024] See also Figure 3 Two rubber blocks 12 are clamped on the top of the top plate 1 , and a pull ring 13 is fixedly installed on the top of the rubber block 12 .

[0025] In this embodiment, please refer to Figure 3 After the memory metal stirring blade 8 moves downward and unfolds, it will tilt in the direction away from the adjusting cylinder 4 and adjust a certain angle, so that the contact area between the memory metal stirring blade 8 and the liquid is larger. At the same time, the perforation opened in the top plate 1 is blocked by the rubber block 12 to prevent the liquid from splashing out. The pull ring 13 is used to facilitate the removal of the rubber block 12 from the inside of the top plate 1.

[0026] In this embodiment, the guide plate 10 limits and restricts the adjustment angle of the memory metal stirring blade 8, and the bottom of the memory metal stirring blade 8 is arc-shaped.

[0027] In this embodiment, the memory metal stirring blade 8 needs to be unfolded when not in use to ensure the integrity and stability of its structure, which also helps to reduce wear and damage caused by repeated folding or deformation.

[0028] In this embodiment, when the memory metal stirring blade 8 enters the interior of the reaction bottle, the memory metal stirring blade 8 needs to be retracted and positioned by the limit seat 9 to prevent the memory metal stirring blade 8 from folding and deforming when entering the bottle mouth, causing damage.

[0029] The working principle of the above embodiment is:

[0030] First, rotate the threaded rod 11 to drive the memory metal stirring blade 8 to move upward and limit the memory metal stirring blade 8 through the limit seat 9. At this time, the memory metal stirring blade 8, the rotating shaft 3 and the adjusting cylinder 4 can be placed into the reaction bottle. At this time, rotate the threaded rod 11 again to drive the memory metal stirring blade 8 to move downward. At this time, the limiting slide bar 7 will rotate inside the rotating shaft 3. When the memory metal stirring blade 8 touches the guide plate 10, it will adjust the angle in the direction of the inclination of the guide plate 10. At this time, the memory metal stirring blade 8 will expand to the left and right sides. Finally, after the rubber block 12 is inserted into the interior of the top plate 1, the adjustment work of the memory metal stirring blade 8 is completed, and the contact area between the memory metal stirring blade 8 and the liquid inside the reaction bottle is increased.
