[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Example 1, please refer to Figures 1 to 5 The present invention provides an embodiment of a liquid beer yeast production and expansion device, comprising a plurality of bases 100 arranged in sequence, wherein each base 100 has a placement groove 101 for placing culture medium, the culture medium extending out of the placement groove 101, and the portion of the culture medium extending out of the placement groove 101 facilitating the handling of the culture medium by workers on the base 100; the bases 100 are connected in pairs by positioning structures 300, and the plurality of bases 100 can be arranged in a front-to-back order;
[0039] The positioning structure 300 includes an insert block 301 and a U-shaped block 302. The insert block 301 is fixed to one end of the back of the base 100, and the U-shaped block 302 is fixed to the other end of the back of the base 100. When the two bases 100 are connected, the protruding part of the insert block 301 is inserted into the inner cavity of the U-shaped block 302. A positioning block 303 is inserted into the insertion hole B3021 on the U-shaped block 302. The inner end of the positioning block 303 is inserted into the insertion hole A3011 opened on the protruding part of the insert block 301. A movable block 304 is fixed to the outer end of the positioning block 303. A spring 305 is provided between the movable block 304 and the U-shaped block 302. The two ends of the spring 305 are fixedly connected to the movable block 304 and the U-shaped block 302 respectively. The elastic coefficient of the spring 305 shall be selected and used by the technical personnel of this profession according to the actual situation.
[0040] Limiting plates 306 are respectively installed at both ends of the movable block 304. The limiting plates 306 are L-shaped, and the lateral section of the limiting plate 306 is matched with the movable block 304 for limiting. After the pulled-out movable block 304 contacts the lateral section of the limiting plate 306, it is limited, so that the inner end of the positioning block 303 is accurately located in the insertion hole B3021, and the positioning block 303 will not be pulled out excessively.
[0041] Before the two operated bases 100 are connected, the operator pulls the movable block 304 outward, and the positioning block 303 moves outward accordingly. The spring 305 is further stretched until the inner end of the positioning block 303 is located in the insertion hole B3021. The protruding section of the insertion block 301 on one base 100 is inserted into the inner cavity of the other U-shaped block 302. The two bases 100 contact each other. The movable block 304 is released. Under the action of the spring 305, the movable block 304 pushes the positioning block 303 back until the inner end of the positioning block 303 is inserted into the insertion hole A3011. The two operated bases 100 are then fixedly arranged, thereby arranging the used culture medium.
[0042] This utility model, by setting up an insert block 301, a U-shaped block 302, a positioning block 303, a movable block 304, and a spring 305, has the advantage of arranging and positioning the culture media after operation to form a whole, preventing misoperation or omission of culture media, and solving the problem of multiple culture media being easily confused before and after operation.
[0043] A slot 103 is provided on one side of the base 100, and an insert 120 is fixed on the other side of the base 100. The insertion end of the insert 120 is arc-shaped, and the insert 120 on one base 100 is inserted into and cooperates with the slot 103 on the other base 100.
[0044] This utility model, by setting a slot 103 and an insert 120, has the advantage that when two bases 100 are connected, the insert 120 on one base 100 is inserted into the slot 103 on the other base 100 to initially limit the position of the base 100, which facilitates the subsequent positioning operation of the positioning structure 300.

[0046] This utility model, by setting up a gantry 200 and a tube trough 201, has the advantages of allowing staff to directly see which items have been used, facilitating comparison, and indicating that the culture medium has been processed after placing the freeze-dried tubes and corresponding culture medium tubes, thus serving as a reminder.
[0047] Working principle: The culture medium is placed in the placement tank 101, and the culture medium extends out of the placement tank 101. The staff adds the yeast and corresponding culture medium tubes from the freeze-dried tubes to the culture medium. After use, the freeze-dried tubes and corresponding culture medium tubes can be inserted into the tube slot 201 for placement. Before the two bases 100 are connected after the operation, the operator pulls the movable block 304 outward, and the positioning block 303 moves outward accordingly. The spring 305 is further stretched. The pulled-out movable block 304 is limited after contacting the transverse section of the limiting plate 306. At this time, the inner end of the positioning block 303 is located in the insertion hole B3021. The protruding section of the insertion block 301 on one base 100 is inserted into the inner cavity of the other U-shaped block 302. The insertion strip 120 on one base 100 is inserted into the slot 103 on the other base 100 until the two bases 100 are in contact. The movable block 304 is released. Under the action of the spring 305, the movable block 304 pushes the positioning block 303 back until the inner end of the positioning block 303 is inserted into the insertion hole A3011. The two bases 100 are then fixedly arranged after the operation.
