AI Technical Summary
Existing benchtop constant temperature shakers are not very effective at fixing test tube containers with dimensions smaller than the distance between adjacent springs, which makes them prone to shaking, sliding, and collisions during the shaking process, increasing the risk of container breakage and sample loss.
The shaker body features a rocker plate design, including an upper spring limiter, a lower spring rod, and a pressure limiting mechanism. By adjusting the rotation of the spring limiter and the use of the fixing strap, the lateral clamping force on the test tube is enhanced, ensuring stable clamping of the container.
It effectively prevents test tubes from shaking and sliding during oscillation, reduces the risk of container breakage and sample loss, and achieves stable fixation of containers of different sizes.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bacterial solution preparation technology, specifically to a soil amendment bacterial solution preparation device with precise temperature control. Background Technology
[0002] Soil-amortizing bacterial solution refers to a liquid preparation containing specific functional microbial strains that can improve the physical, chemical, and biological properties of soil. To prepare soil-amortizing bacterial solution, specific functional microbial strains need to be cultivated under suitable and stable conditions. The cultivation process uses a constant-temperature shaker, which provides the microorganisms with suitable growth temperature and sufficient oxygen (achieved through shaking).
[0003] Currently used benchtop constant temperature shakers have crisscrossing elastic grids installed on the shaker plate. The elastic deformation of the springs is used to laterally limit and fix common culture containers of different sizes and shapes. However, in actual use, for test tubes whose size is smaller than the distance between adjacent springs, the springs cannot effectively fit the side wall of the test tube, and the lateral clamping force provided is very weak. This causes the test tubes to easily shake, slide, and collide with each other within the grid during shaking, thereby increasing the risk of container breakage and sample loss. Utility Model Content
[0004] To address the aforementioned problems, this invention provides a soil amendment bacterial solution preparation device with precise temperature control, thereby solving the issue of poor fixation effect of shakers on test tube containers with dimensions smaller than the spacing between adjacent springs.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a soil amendment bacterial solution preparation device with precise temperature control, including a shaking machine body, a shaking plate, an upper spring limiting member, a lower spring rod, and a pressure limiting mechanism. The shaking machine body is provided with a shaking plate inside. The upper half of the inner wall of the shaking plate is rotatably installed with an upper spring limiting member. There are two sets of upper spring limiting members. One set of upper spring limiting members is rotatably installed inside the shaking plate in the front-back direction with its rotation direction upward. The other set of upper spring limiting members is rotatably installed inside the shaking plate in the left-right direction with its rotation direction downward. The first set of upper spring limiting members is located above the second set of upper spring limiting members.
[0006] A lower spring rod is fixedly installed on the lower half of the inner wall of the rocker plate, a pressure limiting mechanism is fixedly installed on the rear side of the rocker plate, and a bolt corresponding to the pressure limiting mechanism is provided on the top of the rocker plate.
[0007] The upper spring limiting component includes a rotating plate, a main spring rod, a secondary spring rod, a rotating shaft, and a fixed plate. The main spring rod and the secondary spring rod are arranged side by side. There are two sets of rotating plates, and the two sets of rotating plates are fixedly connected to the two ends of the main spring rod and the secondary spring rod, respectively. The rotating shaft is fixedly installed on the side of the rotating plate away from the main spring rod. The rotating shaft is rotatably connected to the rocker plate. The free end of the rotating shaft passes through the surface of the rocker plate and is fixedly installed with a fixed plate. A pin is slidably inserted into the surface of the fixed plate.
[0008] The front and left sides of the rocker are fixedly equipped with two sets of insert plates, which are located on one side and below the fixed plate, respectively, and the insert plates are correspondingly set with the fixed plate and the pins on its surface.
[0009] The bottom inner side of the rocker plate has a groove, and the groove is located below the intersection of the main spring rods that are staggered in the front-back direction and the left-right direction.
[0010] The lower spring rod is located below each set of main spring rods and auxiliary spring rods, and is configured accordingly.
[0011] The pressure limiting mechanism includes a take-up roller, a fixing belt, a positioning plate, a worm gear, and a worm. Support plates are rotatably mounted at both ends of the take-up roller, and the support plates are fixedly connected to the rear side of the rocker plate. The fixing belt is wound around the surface of the take-up roller, and the positioning plate is fixedly mounted at the free end of the fixing belt. A worm gear is fixedly mounted at one end of the take-up roller, and the worm is rotatably mounted on the rear side of the rocker plate, with the worm gear and the worm being meshed together.
[0012] A clamping plate is fixedly installed on the rear side of the rocker, and the clamping plate is inserted into the positioning plate. A bolt is threaded on the top front side of the rocker, and the bolt is correspondingly set with the positioning plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention controls the rotation of the upper spring limiting member by twisting the fixing plate to align the pin on its surface with the plate. This causes the upper spring limiting member to flip upwards to a vertical position in the front-to-back direction and downwards to a vertical position in the left-to-right direction. This changes the horizontal arrangement of the main spring rod and the auxiliary spring rod to a vertical arrangement. For test tubes smaller than the distance between the main and auxiliary spring rods, the test tube is passed between the vertically arranged main and auxiliary spring rods, thus ensuring a tight fit against the test tube's surface and enhancing its lateral clamping force. Push the bottom end of the two sets of perpendicular lower spring rods to the intersection and insert them into the groove of the rocker plate. This prevents the lateral force exerted on the test tube by the vertically arranged main spring rod and auxiliary spring rod from tilting the bottom of the test tube in one direction because they are not on the same horizontal plane. By turning the worm gear, the worm wheel is driven to rotate, and the worm wheel drives the take-up roller to rotate, thereby tightening the fixing band on the surface of the take-up roller. After connecting the positioning plate to the rocker plate, the taut fixing band is used to press and limit the top of the container, preventing relatively slender containers from falling out of the rocker plate.

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0024] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 7 The present invention will be further described below.
[0025] A precision temperature-controlled soil amendment bacterial solution preparation device includes a shaking machine body 1, a shaking plate 2, an upper spring limiting member 3, a lower spring rod 4, and a pressure limiting mechanism 5. The shaking machine body 1 contains the shaking plate 2, a temperature control component, and an oscillation component. This is prior art, and the specific structure can be seen in patent publication number CN213327639U, so it will not be described again. The shaking plate 2 is connected to the shaking end of the oscillation component. The upper spring limiting member 3 is rotatably mounted on the upper half of the inner wall of the shaking plate 2. There are two sets of spring limiting members 3. One set of upper spring limiting members 3 is rotatably installed inside the rocker plate 2 in the front-back direction, with its rotation direction upward. The other set of upper spring limiting members 3 is rotatably installed inside the rocker plate 2 in the left-right direction, with its rotation direction downward. The first set of upper spring limiting members 3 is located above the second set of upper spring limiting members 3. A lower spring rod 4 is fixedly installed on the lower half of the inner wall of the rocker plate 2. A pressure limiting mechanism 5 is fixedly installed on the rear side of the rocker plate 2. A bolt corresponding to the pressure limiting mechanism 5 is provided on the top of the rocker plate 2.
[0026] Specifically, the shaker body 1 controls the temperature and shakes the bacterial liquid container placed on the shaker plate 2 to provide a suitable culture environment. The upper spring limiter 3 and the lower spring rod 4 clamp and fix the bacterial liquid container placed in the shaker plate 2. The pressure limiting mechanism 5 presses and limits the top of the bacterial liquid container.
[0027] The upper spring limiting component 3 includes a rotating plate 301, a main spring rod 302, a secondary spring rod 303, a rotating shaft 304, and a fixing plate 305. The main spring rod 302 and the secondary spring rod 303 are arranged side by side. There are two sets of rotating plates 301, and the two sets of rotating plates 301 are fixedly connected to the two ends of the main spring rod 302 and the secondary spring rod 303, respectively. The rotating shaft 304 is fixedly installed on the side of the rotating plate 301 away from the main spring rod 302. The rotating shaft 304 is rotatably connected to the rocker plate 2, and the rotating shaft 304 and the stationary main spring rod 302 are on the same axis. The free end of the rotating shaft 304 passes through the surface of the rocker plate 2 and is fixedly installed with the fixing plate 305. A pin is slidably inserted into the surface of the fixing plate 305.
[0028] Specifically, the upper part of the container is clamped and fixed by the main spring rod 302 and the auxiliary spring rod 303. The rotation of the rotating shaft 304 drives the upper spring limiting member 3 to rotate around the axis of the main spring rod 302 and the rotating shaft 304, adjusting the relative position of the main spring rod 302 and the auxiliary spring rod 303. The upper spring limiting member 3 is limited and fixed by the pin of the fixing plate 305 after rotation.
[0029] Insert plates are fixedly installed on the front and left sides of the rocker plate 2. There are two sets of insert plates, located on one side and below the fixed plate 305 respectively, and the insert plates are corresponding to the fixed plate 305 and the pins on its surface.
[0030] Specifically, the upper spring limiting member 3 is limited and fixed by connecting the insert plate and the fixed plate 305 with a pin.
[0031] The bottom inner side of the rocker plate 2 is provided with a groove, and the groove is located below the intersection of the main spring rods 302, which are staggered in the front-back direction and the left-right direction respectively;
[0032] Specifically, the groove limits the bottom end of the test tube, which is displaced by the push of the main spring rod 302 and the auxiliary spring rod 303.
[0033] The lower spring rod 4 is located below each set of main spring rods 302 and auxiliary spring rods 303, and is set accordingly to them;
[0034] Specifically, the lower spring rod 4, together with the main spring rod 302 and the auxiliary spring rod 303, stably clamps and fixes the container, and the groove is used to limit and fix the bottom end of the test tube that may shift.
[0035] The pressure limiting mechanism 5 includes a take-up roller 501, a fixing belt 502, a positioning plate 503, a worm wheel 504, and a worm 505. Support plates are rotatably mounted at both ends of the take-up roller 501, and the support plates are fixedly connected to the rear side of the rocker plate 2. The fixing belt 502 is wound around the surface of the take-up roller 501. The positioning plate 503 is fixedly mounted at the free end of the fixing belt 502. A limiting groove is opened at the bottom of the positioning plate 503. The worm wheel 504 is fixedly mounted at one end of the take-up roller 501. The worm 505 is rotatably mounted at the rear side of the rocker plate 2, and the worm wheel 504 and the worm 505 are meshed together. A dial is fixedly mounted at the free end of the worm 505.
[0036] Specifically, the top of the slender container is pressed and limited by the fixing belt 502, the free end of the fixing belt 502 is fixed to the top of the rocker plate 2 by the positioning plate 503, and the worm wheel 504 and worm 505 are used to adjust the tightness of the surface of the fixing belt 502 after it is attached to the top of the container, and to prevent the winding roller 501 from rotating on its own.
[0037] A retaining plate is fixedly installed on the rear side of the rocker plate 2, and the retaining plate is inserted into the positioning plate 503. A bolt is threaded on the top front side of the rocker plate 2, and the bolt is correspondingly set with the limiting groove of the positioning plate 503.
[0038] Specifically, the idle positioning plate 503 is fixed by a clamping plate, and the positioning plate 503 is fixed to the top front side of the rocker plate 2 by bolts passing through the limiting groove of the positioning plate 503, so that the fixing strap 502 passes over the top of the rocker plate 2 to press and limit the container.
[0039] In summary: When using this utility model, the operator can utilize the deformable main spring rod 302, secondary spring rod 303, and lower spring rod 4 to stably limit and fix containers larger than the spacing between them, depending on the container used to fill the bacterial solution. However, if the container size is smaller than the spacing, to ensure stable clamping of the container, the pin at the fixing plate 305 can be pulled to separate it from the plate, and the fixing plate 305 can be twisted to drive the rotating shaft 304 to rotate inside the rocker plate 2, located at the upper edge of the front... The upper spring limiting member 3 in the rear direction flips upward, and the upper spring limiting member 3 located below in the left-right direction flips downward, pushing the pin at the fixing plate 305 to connect and limit its position with the insertion plate. The main spring rod 302 and the auxiliary spring rod 303 change from a horizontal arrangement to a vertical arrangement. The container is inserted between them, passing through the interior of the two sets of upper spring limiting members 3 until the bottom of the container reaches the intersection point of the lower spring rod 4. According to the direction of the pushing force applied to the container by the main spring rod 302 and the auxiliary spring rod 303, the bottom of the container tilts in the direction of the force. The bottom end of the container is aligned with the intersection point of the lower spring rod 4, and the lower spring rod 4 is pushed open so that the bottom end of the container is inserted into the groove of the rocker plate 2. The container is fixed in place by the groove and the lower spring rod 4 adhering to the bottom end of the container. If the container is relatively long and thin, the upper spring limiting member 3 and the lower spring rod 4 cannot apply vertical force to the container. To prevent the container from detaching, the positioning plate 503 is removed from the clamping plate on the back side of the rocker plate 2. The worm gear 505 is rotated to drive the worm wheel 504, and the worm wheel 504 drives the take-up roller 501 to rotate. The fixing band 502 on the surface of the take-up roller 501 is unfolded, and the positioning plate 503 is pulled to the bolt on the front side of the top of the rocker plate 2. The positioning plate 503 is fixed by the bolt adhering to the limiting groove of the positioning plate 503. The worm gear 505 is turned to control the take-up roller 501 to take up the fixing band 502, so that the taut fixing band 502 adheres to the top of the container and applies pressure to it to achieve stable placement of the container. If the bacterial liquid has a high oxygen demand, a U-shaped tube needs to be inserted into the top of the container to prevent the fixing band 502 from blocking the ventilation holes at the top.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
