[0002] A fermentation shaker is a device used in microbial fermentation experiments. It mainly promotes the growth and metabolism of microorganisms through oscillation and temperature control. Through oscillation, the substrate or metabolites are better transferred and function within the system.

[0003] Typically, when using a fermentation shaker, the fermentation solution is first poured into a container, then the container is placed on the shaker plate. After that, it is fixed in place by positioning clamps, and the shaker can be started to create a swaying and oscillating working state for the container. However, the clamps on it usually have a single clamping angle. For round containers, it is difficult to clamp and position round containers of different diameters, and different clamps need to be changed. Furthermore, for some rectangular containers, the traditional clamps for holding round containers are not applicable, which has a large limitation on its applicability. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please refer to the following: Figures 1-6The multi-angle adjustable clamping mechanism for a fermentation shaker includes: a shaker plate 1 and a support frame 2 fixedly installed on the top of the shaker plate 1. The support frame 2 has a semi-enclosed structure. A main rotating shaft 3 is rotatably installed inside the support frame 2, and a servo motor is fixedly installed on one side of the outer wall of the support frame 2. Its output shaft is fixedly connected to one end of the main rotating shaft 3. Three sets of transmission units are provided on the main rotating shaft 3. Each transmission unit includes a bidirectional threaded sleeve 4, two linkage arms 5, two sockets 6, and two slots 7. The bidirectional threaded sleeve 4 is fixedly sleeved on the main rotating shaft 3. The two linkage arms 5 are threaded onto the bidirectional threaded sleeve 4. The two sockets 6 are respectively fixedly installed on one side of the two linkage arms 5, and the two slots 7 are respectively opened on the two sockets 6. Furthermore, a clamping mechanism is provided on one of the transmission units. The clamping mechanism includes two bearing arms 8. The two bearing arms 8 are fixedly installed in the corresponding slots 7 by bolts, which can be easily disassembled and assembled. The two bearing arms 8 are fixedly installed on the side that is close to each other. There are multiple hinge seats 9, each hinge seat 9 has two clamping pieces 10 hinged to it, each clamping piece 10 has a fixed sliding rod 11, each sliding rod 11 has a movable block 12 slidably mounted on it, and each movable block 12 has a hinged linkage rod 14. Each linkage rod 14 passes through a corresponding bearing arm 8 and is slidably connected to the corresponding bearing arm 8. The same bidirectional threaded rod 15 is rotatably mounted on two bearing arms 8. Two pull bars 13 are threaded onto the bidirectional threaded rod 15. The side of the two pull bars 13 that is close to each other is fixedly connected to the corresponding linkage rod 14. In this way, by rotating the bidirectional threaded rod 15, the angle between the corresponding clamping pieces 10 can be adaptively adjusted by pulling the linkage rod 14. In addition, a tightening screw is threaded onto one of the bearing arms 8, and its end abuts against the bidirectional threaded rod 15 to prevent the bidirectional threaded rod 15 from rotating. Furthermore, handwheels are fixedly mounted at both ends of the bidirectional threaded rod 15 to facilitate driving the bidirectional threaded rod 15 to rotate.

[0022] In the above method, in order to ensure that the linkage arm 5 can only perform linear movement and prevent it from rotating, a limit slide bar is fixedly installed inside the support frame 2. The limit slide bar passes through the linkage arm 5 and is slidably connected to the linkage arm 5.

[0023] In this method, in order to provide support for the side of the bearing arm 8 away from the support frame 2 and prevent that side from tilting due to gravity, a support plate 16 is fixedly installed on the rocker plate 1. Multiple support balls 17 are movably embedded in the top of the support plate 16. The same sliding support plate 18 is fixedly installed on the top of the two bearing arms 8. The bottom of the sliding support plate 18 is in contact with the corresponding support ball 17.

[0024] In this method, in order to provide the clamping piece 10 with maximum angular adjustment, two rectangular hinge slots are opened on each of the multiple hinge seats 9. In the rectangular hinge slots, the two outermost vertically distributed sides are both set as openings. The multiple clamping pieces 10 rotate in the multiple rectangular hinge slots respectively. When the two included angles gradually increase and the rotating clamping pieces 10 finally contact the side wall of the rectangular hinge slot, it indicates that the left and right symmetrical clamping pieces 10 are in a horizontal state, thereby enabling the rectangular container to be clamped and positioned.

[0025] The working principle of the multi-angle adjustable clamping mechanism for a fermentation shaker provided by this utility model is as follows:

[0026] In this clamping mechanism, the number of clamping mechanisms can be selected according to the actual number of containers.

[0027] When it is necessary to fix the round container on the shaking table plate 1, first turn the screw back to tighten it and separate it from the double-threaded rod 15. Then turn the double-threaded rod 15 counterclockwise to make the two pull bars 13 move away from each other. As a result, under the drive of the linkage rod 14, the angle between the corresponding two clamps 10 gradually increases until the appropriate angle is adjusted. Then tighten the screw back to use the tightening screw to form a positioning effect on the double-threaded rod 15.

[0028] Then place the circular container between the four corresponding clamping plates 10, then start the servo motor, and the two bearing arms 8 move towards each other until the four corresponding clamping plates 10 have all contacted the circular container. Then the servo motor can be turned off, and the clamping and positioning of the circular container is completed.

[0029] When it is necessary to clamp and position a rectangular container, first perform the same operation as above, rotate and tighten the set screw, and then rotate the bidirectional threaded rod 15 counterclockwise. At this time, the angle between the corresponding two clamping plates 10 gradually increases until the multiple rotating clamping plates 10 all contact the side of the corresponding rectangular hinge slot. Then stop rotating the bidirectional threaded rod 15. At this time, the corresponding left and right clamping plates 10 are in a horizontal state. Then place the rectangular container between the corresponding four clamping plates 10, and then start the servo motor to clamp and position it using the horizontal clamping plates 10.

[0030] In subsequent use, when a large number of clamping mechanisms are required, the next clamping mechanism can be removed, its two bearing arms 8 can be inserted into the two mounting slots 7 in the corresponding transmission unit, and then fixed with bolts.

[0031] Compared with related technologies, the multi-angle adjustable clamp mechanism for fermentation shakers provided by this utility model has the following advantages:

[0032] This utility model provides a multi-angle adjustable clamping mechanism for a fermentation shaker. Through the cooperation of the movable block 12, the pull bar 13 and the linkage rod 14, the angle between the two corresponding clamping pieces 10 can be adjusted, thereby meeting the clamping and positioning work of circular containers of different diameters. Furthermore, by pulling the clamping pieces 10 to contact the side wall of the rectangular hinge slot, the left and right corresponding clamping pieces 10 are made to be in a horizontal state, thereby enabling the clamping and positioning of rectangular containers, and greatly improving the applicability.
