[0002] Pouring plates refers to the process of pouring melted solid culture medium (usually containing 1.5% to 2% agar) into a sterile petri dish while it is still hot, and allowing it to cool to form a uniform solid layer.
[0003] The entire process of pouring the plates must be carried out in a sterile area next to the flame of an alcohol lamp.
[0004] When performing the plate-pouring operation, the conical flask needs to be held in the right hand, and the mouth of the flask is sterilized by flame. However, in the existing technology, when the culture medium in the conical flask is poured into the petri dish, because the conical flask is tilted, the culture medium at the mouth of the conical flask is easily exposed to the outside environment and contaminated with bacteria. After pouring one culture medium, when the conical flask is placed vertically on the experimental table, the culture medium at the mouth of the conical flask will flow back into the conical flask and mix with the culture medium in the flask, causing the culture medium in the flask to be contaminated, which will lead to the failure of the experiment.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] Reference Figure 1 As shown, a flat plate inverting auxiliary device includes a bracket 1, a rotating component 2, a clamping component 4, and a bottle holder 5; the two ends of the rotating component 2 are respectively fixedly connected to the upper ends of two symmetrically arranged brackets 1; the middle part of the rotating component 2 is detachably connected to the clamping component 4 for clamping the neck of the conical bottle 6 through a connecting block 3; the bottle holder 5 is detachably connected to the lower end of the conical bottle 6.
[0027] It should be noted that the support 1 can support the other components; the rotating part 2 can drive the conical flask 6 clamped by the clamping part 4 to rotate in one direction, thereby effectively preventing the solution inside the conical flask 6 from flowing back when making sterile culture dishes, causing the culture medium inside the conical flask 6 to be contaminated; the bottle holder 5 can prevent the bottom of the conical flask 6 from getting too hot and making it difficult to hold and rotate by hand.
[0028] Specifically, support 1 is an isosceles triangular support, with the base thickness being more than twice the thickness of the hypotenuse. Isosceles triangular supports offer excellent stability. In this application, to improve the stability of the inverted flat plate auxiliary device during experiments on a clean bench, the isosceles triangular support is constructed with a base thickness greater than twice the thickness of the hypotenuse, which lowers the center of gravity of support 1 and ensures stability.
[0029] The rotating component 2 includes a support rod 21 and a connecting seat 22; both ends of the support rod 21 are located within the connecting seat 22 and can rotate in one direction relative to the connecting seat 22. In this application, the unidirectional rotation of the support rod 21 and the connecting seat 22 is in the form of a ratchet. After the conical flask 6 is fixed to the clamping component 4, the operator can slowly tilt the conical flask 6 around the rotating component 2 by supporting the bottle support 5 at the lower end of the conical flask 6, ensuring that the conical flask 6 cannot rotate in the opposite direction, thereby preventing backflow and contamination of the culture medium at the bottle mouth; Figure 4As shown, the support rod 21 has connecting seats 22 at both ends; the support rod 21 is connected to the rotating round rod 23 by a torsion spring; the rotating round rod 23 is fixedly connected to a pawl 24, which can cooperate with the gear inside the connecting seat to lock the rotating part 2. Its working method is easily understood by those skilled in the art and is the prior art; the adjustment range can be adjusted by the number of teeth of the gear inside the connecting seat, and those skilled in the art can make a reasonable selection according to the amount of culture medium poured in.
[0030] Specifically, such as Figure 2 As shown, the clamping member 4 includes a clamping seat 41, a first clamping piece 42, a second clamping piece 43, a guide rod 44, and a spring 45; the first clamping piece 42 is fixedly connected to the middle of the clamping seat 41; a first cavity 46 is provided on one side of the clamping seat 41; the second clamping piece 43 is movable along the length direction of the first cavity 46 and placed in the first cavity 46; the guide rod 44 is arranged along the length direction of the first cavity 46, one end of which passes through the second clamping piece 43 and is fixedly connected to the end of the first clamping piece 42 located in the clamping seat 41, and the other end is fixedly connected to the end wall of the clamping seat 41; the spring 45 is sleeved on the guide rod 44, one end of which abuts against the second clamping piece 43, and the other end of which abuts against the end wall of the clamping seat 41. The clamping seat 41 facilitates the setting of other components; the first clamping piece 42 and the second clamping piece 43 cooperate to clamp the conical bottle 6; the first clamping piece 42 is fixed on the clamping seat 41 and remains stationary; the second clamping piece 43 contacts the first clamping piece 42 through the elastic force of the spring 45; the guide rod 44 can prevent the spring 45 from deflecting; the number of springs 45 can be selected according to the size of the first clamping piece 42 and the second clamping piece 43 or the elastic coefficient of the spring 45 can be changed.
[0031] like Figure 2 As shown, the first clamping piece 42 located outside the clamping seat 41 has the same structure at one end and the second clamping piece 43 located outside the clamping seat 41 at the other end, and the ends do not contact each other. They are constructed as relatively curved arc surfaces to facilitate clamping the conical bottle 6. The fact that the ends do not contact each other makes it convenient to clamp conical bottles 6 of a certain size within a certain range.
[0032] Specifically, such as Figure 3 As shown, the bottle holder 5 includes a bottle holder base 51, a double-threaded lead screw 52, a lead screw seat 53, and an arc plate 54. A second cavity 55 is formed inside the bottle holder base 51. The double-threaded lead screw 52 passes through the second cavity 55 and is rotatably connected to the bottle holder base 51. A through groove 56 is formed above the second cavity 55. Two lead screw seats 53 are threadedly connected to the threads of the double-threaded lead screw 52 in opposite directions. The lead screw seats 53 extend out of the through groove 56 and are fixedly connected to the arc plate 54, which is inclined towards the center of the bottle holder base 51. The bottle holder base 51 is circular, facilitating the installation of other components. The double-threaded lead screw 52 can drive the two lead screw seats 53 located on it to move towards or away from each other. The arc plate 54 is fixedly connected to the lead screw seat 53, and the two arc plates 54 facilitate clamping the bottom of the conical bottle 6.
[0033] To facilitate the rotation of the double-threaded lead screw 52, knobs 57 are fixedly connected to both ends of the double-threaded lead screw 52. Turning the knobs 57 can adjust the distance between the two lead screw seats 53, thereby fixing or loosening the conical bottle 6.
[0034] The working principle of this utility model:
[0035] First, the heated conical flask 6 is placed on the flask holder 5 and fixed in place. The flask 6 is then secured to the holder 5 by turning the knob 57, preventing burns to workers caused by the heated flask 6. Next, the conical flask 6 is clamped onto the clamping member 4 after being supported by the holder 5. The clamping member 4 facilitates the fixation of the conical flask 6. During the pouring operation, the worker holds the holder 5 and rotates it. The culture medium in the conical flask 6 flows from the flask opening into the petri dish, completing the pouring of one petri dish. At this time, because the support rod rotates in one direction relative to the connecting seat, it effectively prevents the culture medium at the flask opening from flowing back and contaminating the culture medium inside the conical flask 6. After the conical flask 6 has been poured, the flask 6 connected to the clamping member 4 is removed, and the rotating member 2 is rotated to return it to its starting position.
[0036] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
