Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial culture technology, specifically to a microbial culture shaker. Background Technology
[0002] A microbial shaker is a commonly used laboratory instrument belonging to the category of biochemical instruments. It is widely used for bacterial culture, fermentation, hybridization, biochemical reactions, and enzyme and tissue research. Its working principle is based on the interaction of gravity and centrifugal force. Through the mechanical motion of the shaker, the liquid in the culture container is agitated, thereby promoting the growth and reproduction of microorganisms.
[0003] The commonly used shaking method in the existing technology is a linear reciprocating motion. The defect of this shaking method is that the culture medium inside the culture bottle can only be shaken laterally as much as possible, and the shaking in other directions (such as vertical shaking back and forth) is small; resulting in limited mixing uniformity, which affects the uniformity of microbial growth and metabolism.
[0004] For example, the utility model patent with patent authorization announcement number CN 220183196 U discloses a shaker for microbial culture. The specification describes that the output end of the drive motor drives the drive disk to rotate, the drive disk drives the locking shaft to rotate, and the locking shaft cooperates with the locking groove at the bottom of the limiting frame to drive the limiting frame to shake laterally, thereby causing the microbial culture dish to shake. This shaking method is actually quite limited for uniform microorganisms and culture media. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a microbial culture shaker, which solves the problems mentioned in the background section.
[0007] (II) Technical Solution

[0009] Preferably, the groove sidewall is provided with multiple sliding openings, and a clamping block is slidably disposed inside the sliding opening. The side of the clamping block near the rotating column is an arc-shaped surface, and the side away from the rotating column is a flat surface. Multiple bolts are also threaded into the outer circumferential sidewall of the positioning seat, and the threaded end of the bolt extends into the sliding opening and abuts against the clamping block.
[0010] Preferably, a guide block is fixedly connected to the bottom of the support plate, and a horizontal guide rod is fixedly connected between the inner walls of both sides of the bottom shell, with the guide rod movably passing through the guide block.
[0011] Preferably, the guide block has a strip-shaped opening at the bottom, a motor is fixedly installed inside the bottom of the bottom shell, a connecting rod is fixedly connected to the output end of the motor, a vertically upward guide pin is fixedly connected to the end of the connecting rod, and the upper end of the guide pin is inserted into the strip-shaped opening.
[0012] Preferably, the limiting brackets are distributed in a matrix on the surface of the bearing plate, and the limiting brackets are covered with rubber rings.
[0013] Preferably, the guide rod has a round rod-shaped structure, and the number of guide rods is at least two.
[0014] (III) Beneficial Effects
[0015] This invention provides a microbial culture shaker, which has the following beneficial effects:
[0016] 1. In this utility model, the rotating column can be rotated and adjusted on the top of the positioning seat, thus allowing adjustment of the orientation of multiple culture bottles placed on the top of the support plate; in conjunction with the motor driving the connecting rod to rotate, the connecting rod then drives the guide pin to rotate, and the guide pin pushes the guide block to move back and forth linearly, thereby realizing the reciprocating movement of the support plate, and ultimately realizing the shaking of multiple culture bottles; by repeatedly adjusting the orientation of the culture bottles, the culture medium and microorganisms inside the culture bottles are uniformly mixed, promoting the uniformity of microbial growth and metabolism.
[0017] 2. In this utility model, by rotating each bolt, the bolt pushes the clamping block to move linearly inside the sliding port, and finally the arc-shaped surface of the clamping block abuts against the circumferential surface of the rotating column to achieve the purpose of locking the rotating column; ensuring that the rotating column will not rotate during the shaking of the culture bottle, thus ensuring the safety and stability of use.

[0024] 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.
[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a microbial culture shaker, including a bottom shell 1 and a support plate 2 that can move back and forth on the bottom shell 1. A positioning seat 3 is fixedly connected to the top of the support plate 2. A rotating column 5 is rotatably inserted into a groove 301 opened on the top of the positioning seat 3. The upper end of the rotating column 5 extends to the outside of the groove 301 and is fixedly connected to a bearing plate 4. A plurality of limiting brackets 12 for placing culture bottles are fixedly provided on the top of the bearing plate 4.
[0026] Since the support plate 2 can move back and forth in a straight line, it can ultimately shake multiple culture bottles; the rotating column 5 can be rotated on the top of the positioning seat 3, so the orientation of multiple culture bottles placed on the top of the support plate 4 can be adjusted; by adjusting the orientation of the culture bottles multiple times, the culture medium and microorganisms inside the culture bottles can be mixed evenly, promoting the uniformity of microbial growth and metabolism.
[0027] The limiting bracket 12 is a component used to limit the position of the culture bottle. Most culture bottles have a round bottom structure. The bottom of the round bottom culture bottle (such as Erlenmeyer flasks and round bottom reagent bottles) has no flat support. When placed statically, it is easy to tilt to the side. When the shaker is shaken dynamically, it is even easier to deviate from its original position due to centrifugal force or vibration. Therefore, the core of the limiting bracket 12 is to fix the bottle body through "fitting positioning".
[0028] Reference Figures 4 to 5 Multiple sliding openings 302 are provided on the side wall of the groove 301. A clamping block 6 is slidably arranged inside the sliding opening 302. The side of the clamping block 6 near the rotating column 5 is an arc-shaped surface, and the side away from the rotating column 5 is a flat surface. Multiple bolts 13 are also threaded into the outer circumferential side wall of the positioning seat 3. The threaded end of the bolt 13 extends into the sliding opening 302 and abuts against the clamping block 6.
[0029] By rotating each bolt 13, the bolt 13 pushes the clamping block 6 to move linearly inside the slide 302, eventually causing the arc-shaped surface of the clamping block 6 to come into contact with the circumferential surface of the rotating column 5, thereby achieving the purpose of locking the rotating column 5; ensuring that the rotating column 5 will not rotate during the shaking of the culture bottle, thus ensuring the safety and stability of use.
[0030] Reference Figure 3 A guide block 7 is fixedly connected to the bottom of the support plate 2, and a horizontal guide rod 8 is fixedly connected between the inner walls of both sides of the bottom shell 1. The guide rod 8 is movably connected through the guide block 7.
[0031] Ensure that the support plate 2 can only move laterally along the guide rod 8 to avoid vertical jumping or lateral displacement caused by oscillation force. The bearing plate 4 and the culture bottle on its top can only move laterally back and forth. Ensure the stability of the culture bottle shaking. Transfer the weight of the support plate 2 to the guide rod 8 through the guide block 7, and then distribute it to the bottom shell 1 through the guide rod 8 to avoid structural deformation caused by excessive force at a single point.
[0032] Reference Figures 1 to 4 The bottom of the guide block 7 has a strip-shaped opening 701. The bottom of the bottom shell 1 has a motor 9 fixedly installed. The output end of the motor 9 is fixedly connected to a connecting rod 10. The end of the connecting rod 10 is fixedly connected to a vertically upward guide pin 11. The upper end of the guide pin 11 is inserted into the strip-shaped opening 701.
[0033] In order to drive the multiple culture bottles on the top of the support plate 4 to move back and forth horizontally, the start motor 9 drives the connecting rod 10 to rotate, and the connecting rod 10 drives the guide pin 11 to rotate. The guide pin 11, through cooperation with the strip opening 701, pushes the guide block 7 to move back and forth linearly, thereby realizing the reciprocating movement of the support plate 2, and finally realizing the shaking of the multiple culture bottles on the top of the support plate 4.
[0034] Motor 9 requires a starting capacitor and a running capacitor. Through the phase splitting effect of the capacitor, the 220V single-phase AC power is converted into "simulated two-phase power" to generate a rotating magnetic field to drive the rotor of motor 9 to rotate. The power supply method is a conventional technical means, so it will not be described in detail.
[0035] Reference Figures 1 to 2 The limiting brackets 12 are distributed in a matrix on the surface of the bearing plate 4, and the limiting brackets 12 are covered with rubber rings.
[0036] The limiting bracket 12 consists of a ring and multiple support bars set at the bottom of the ring. The culture bottle needs to be inserted into the ring, and the bottom of the culture bottle should be in contact with the support plate 4. The rubber ring set on the ring can fully compensate for the gap, improve the purpose of pressing and limiting the culture bottle, and reduce the wear on the surface of the culture bottle when in contact with it.
[0037] Reference Figure 3The guide rod 8 has a round rod-shaped structure, and there are at least two guide rods 8.
[0038] The guide rod 8, with its round rod structure, is relatively simple to manufacture. High precision and surface quality requirements can be easily achieved through conventional machining processes such as turning and grinding, which helps reduce production costs and improve production efficiency. The outer surface of the round rod is a continuous cylindrical surface, and the contact between it and mating parts such as the guide block 7 is relatively uniform, which can provide a stable guiding effect, reduce friction and wear during movement, and ensure the smoothness and accuracy of movement.
[0039] At least two guide rods 8 can constrain the moving parts in multiple directions, enabling them to move more stably along the predetermined direction. Two or more guide rods 8 can jointly bear the weight and load of the moving parts, thereby improving the load-bearing capacity of the entire system.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
