Abstract
Description
Technical Field
[0001] This utility model belongs to the field of microbial strain transfer technology, specifically relating to an auxiliary device for shake flask strain transfer. Background Technology
[0002] Shaking flasks are one of the most widely used glasswares in microbial culture. Due to their structural characteristics, namely, the neck of the flask is slightly deep and the neck is straight upward, the inoculation personnel need to hold the shaking flask at an angle with one hand and use the inoculation needle with the other hand to complete the inoculation operation during the actual inoculation process. The above-mentioned hand-held shaking flask inoculation method has certain drawbacks: (1) In order to avoid inoculation, the mouth of the shaking flask is close to the flame of the alcohol lamp during the inoculation process, which can easily cause hand burns; (2) Holding the shaking flask can easily cause the liquid culture medium to shake, affecting the quality of inoculation. Utility Model Content
[0003] This invention addresses the shortcomings of the prior art by providing a shake flask culture transfer auxiliary device for supporting tilted shake flasks, replacing the traditional hand-held shake flask method, and effectively reducing the chance of shaken flasks and hand burns from flames.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A shake flask culture transfer auxiliary device includes a support base, the upper part of which is provided with a receiving groove and a pressure bearing member. The pressure bearing member is located on one side of the receiving groove and is provided with a positioning groove for fixing the neck of the shake flask. The shake flask is placed at an angle in the receiving groove, and the neck of the shake flask is embedded in the positioning groove.
[0006] Preferably, the inner wall of the positioning groove is provided with an elastic element.
[0007] Preferably, the horizontal cross-section of the receiving groove is elliptical.
[0008] Preferably, one end of the pressure-bearing member is hinged to the support base, and the other end is provided with an angle adjustment component for adjusting the tilt angle of the pressure-bearing member between it and the support base.
[0009] Preferably, the angle adjustment assembly includes a fixing member, a screw, and an upper adjusting nut. The fixing member has a slotted groove. The upper end of the screw is hinged to the bottom of the pressure-bearing member, and the lower end passes through the slotted groove and is slidably connected to the slotted groove. The upper adjusting nut is pressed against the upper surface of the fixing member and is threadedly connected to the screw.
[0010] Preferably, the screw is also threaded with a lower adjusting nut, which is located below the fixing member.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] (1) This utility model is an auxiliary tool for transferring microbial strains in shake flasks. When transferring microbial strains, the shake flask is placed at an angle in the receiving groove, with the bottom sides of the flask abutting against the inner wall edge of the receiving groove. The neck of the shake flask is embedded in the positioning groove, and the elastic element can effectively fix the shape of the flask. At this time, the alcohol lamp is placed on one side below the mouth of the shake flask, which can effectively avoid the microbial strain from being contaminated, reduce the probability of hand burns, and reduce the risk of shaking the shake flask, thereby improving the quality of microbial strain transfer.
[0013] (2) This utility model can adjust the tilt angle of the pressure-bearing component and the shaking bottle by adjusting the height position of the upper and lower adjusting nuts on the screw. It is simple and convenient to operate, highly practical and widely applicable. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] like Figures 1 to 3 As shown, a shake flask culture transfer auxiliary device includes a support base 1, an upper part of which is provided with a receiving groove 2 and a pressure bearing member 3. The pressure bearing member is located on one side of the receiving groove and has a positioning groove 4 for fixing the neck of the shake flask. The shake flask is placed at an angle in the receiving groove, with the bottom sides of the flask abutting against the inner wall of the receiving groove. The neck of the shake flask is embedded in the positioning groove, which realizes the tilted and fixed support of the shake flask, replacing the manual hand transfer method. Placing an alcohol lamp on one side below the mouth of the shake flask can effectively avoid the contamination of the culture, reduce the probability of hand burns, and reduce the risk of shaking of the shake flask, thereby improving the quality of culture transfer.
[0023] like Figure 2 and Figure 3 As shown, the inner wall of the positioning groove is provided with an elastic element 5, which can effectively improve the fixing effect of the bottle neck. The horizontal cross section of the receiving groove is elliptical, which makes the fixing effect better after the bottle is tilted and laid down. Moreover, the placement position can be adaptively adjusted according to the different sizes of the bottle.
[0024] like Figure 1 and Figure 2 As shown, one end of the pressure-bearing component is hinged to the support base, and the other end is provided with an angle adjustment assembly between the pressure-bearing component and the support base to adjust the tilt angle of the shaking bottle, thereby achieving the purpose of adjusting the tilt angle of the shaking bottle and improving the practicality and applicability of this utility model. The angle adjustment assembly includes a fixing component 6, a screw 7, and an upper adjusting nut 8. A strip groove 9 is provided on the fixing component. The upper end of the screw is hinged to the bottom of the pressure-bearing component, and the lower end passes through the strip groove and is slidably connected to the strip groove. The upper adjusting nut is pressed against the upper surface of the fixing component and is threadedly connected to the screw, which can effectively support the pressure-bearing component. In this embodiment, a lower adjusting nut 10 is also threadedly connected to the screw, and the lower adjusting nut is located below the fixing component. By fixing the upper and lower adjusting nuts to both sides of the fixing component, the position of the pressure-bearing component can be further effectively fixed, reducing the risk of shaking of the shaking bottle.
[0025] In use, the shake flask is placed at an angle in the receiving groove 2, with the bottom sides of the flask abutting against the inner edge of the receiving groove 2. The neck of the shake flask is embedded in the positioning groove 4, and the elastic element 5 effectively fixes the shape of the flask. Placing an alcohol lamp below the mouth of the shake flask effectively prevents contamination of the inoculum, reduces the probability of hand burns, and minimizes the risk of shaking, thereby improving the quality of inoculum transfer. When it is necessary to adjust the tilt angle of the shake flask, simply rotate the upper adjusting nut 8 and the lower adjusting nut 10 to adjust their height position on the screw 7. The operation is simple and convenient.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
