shaker for biochemistry laboratory

Abstract

This invention discloses a shaker for a biochemical laboratory, comprising a main body and a bed surface mounted on the main body. A base plate is detachably mounted on the bed surface, and a vertically adjustable top plate is provided on the base plate. Multiple clamping drive mechanisms are evenly arranged between the top plate and the base plate. When the top plate is raised or lowered, each clamping drive mechanism is driven to operate simultaneously. This shaker for a biochemical laboratory differs from existing technologies in that, when using a biological shaker for cell culture, it can selectively choose a suitable clamping configuration based on the type of culture container, thereby providing effective shaking positioning for the culture container and ensuring stable and efficient shaking culture. Furthermore, during container placement and positioning, the top plate can be raised or lowered simultaneously to synchronously position or cancel the positioning of all containers on the top plate, eliminating the need for laborious flask clamp expansion to position each container individually.

Description

Technical Field

[0001] This invention relates to the field of shaker technology, specifically to a shaker for use in a biochemical laboratory. Background Technology

[0002] Biotechnology is an emerging and comprehensive discipline. Modern biotechnology integrates multiple disciplines such as genetic engineering, molecular biology, biochemistry, genetics, cell biology, embryology, immunology, organic chemistry, inorganic chemistry, physical chemistry, physics, informatics, and computer science. It can be used to study the laws of life activities and provide products to serve society.

[0003] In biological experiments, cell culture is required. Current technology generally involves sealing primary cells in a container, providing them with a suitable temperature, and then rapidly culturing them using a shaker.

[0004] Existing shaker structures rely on relatively simple container positioning methods. Some use staggered springs to position the flask by inserting it, while others use flask clamps. However, these methods are primarily designed for conical flasks and are unsuitable for flat, open containers like petri dishes. In such cases, existing container positioning clamps often need to be removed, which is extremely cumbersome. Furthermore, because these flat, open containers are difficult to tip over during shaking, there are no suitable clamps specifically designed for shaker culture. Simply placing the container on the shaker surface, while generally harmless, can lead to movement during continuous shaking. Although it may not tip over, there is a risk of it falling off the surface during sustained movement. Therefore, we propose a shaker for biochemistry laboratories. Summary of the Invention

[0005] The purpose of this invention is to provide a shaker for a biochemical laboratory to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shaker for a biochemistry laboratory, comprising a main body and a bed surface mounted on the main body, a base plate detachably mounted on the bed surface, and a top plate that can be vertically lifted and lowered on the base plate;

[0007] Multiple clamping drive mechanisms are evenly arranged between the top plate and the bottom plate, and when the top plate is raised or lowered, each clamping drive mechanism is driven to operate simultaneously.

[0008] Furthermore, the clamping drive mechanism is equipped with a dual-morphological positioning component that can simultaneously adapt to flasks and culture dishes. When each of the clamping drive mechanisms is activated, the dual-morphological positioning component is driven to activate simultaneously to position all the culture containers.

[0009] Preferably, a screw is threaded through the top plate, the bottom end of the screw is rotatably connected to the bottom plate, and a gripping member is installed on the top plate. Rotating the gripping member will drive the screw to rotate, thereby raising and lowering the top plate.

[0010] Preferably, at least four screws are provided, and they are respectively located at the four corners of the top plate. A sprocket is installed on the outside of each screw, and a chain is provided on the outside of each sprocket. The four sprockets move synchronously using the chain, so that the four screws rotate synchronously.

[0011] Preferably, the grip includes a non-slip knob mounted on the top of the screw.

[0012] Preferably, guide rollers are installed on the top plate at positions between adjacent screws, and the chain passes around the inside of each guide roller.

[0013] Preferably, a plurality of through slots are provided on the top plate, and the clamping drive mechanism includes a rotating shaft installed in each of the through slots, and a bearing seat is installed on each of the rotating shafts, and the dual-form positioning member is installed on the bearing seat.

[0014] It also includes a second rotating shaft installed at the bottom of the top plate, a driving collar is provided on the second rotating shaft, and a first actuating member is provided between the driving collar and the bearing seat. A guide collar is provided on the bottom plate at the position corresponding to the driving collar. Both the driving collar and the guide collar are circular ring structures. The second actuating member is provided between the driving collar and the guide collar. When the top plate moves relative to the bottom plate, the second actuating member is used to drive the driving collar to rotate. When the driving collar rotates, the first actuating member is used to drive each bearing seat to move and clamp the dual-form positioning member.

[0015] Preferably, the support seat is a cylindrical structure, and a spiral groove is provided on the side of the support seat. The actuating member includes a top post installed on the drive collar. The top end of the top post extends into the spiral groove and is slidably connected to its inner wall so as to drive the support seat to deflect when the drive collar rotates.

[0016] Preferably, the second actuating member includes a second actuating post installed on the inner wall of the guide collar, and a second spiral groove is provided on the outer side of the drive collar. The second actuating post extends into the second spiral groove and is slidably connected to its inner wall so as to drive the drive collar to rotate when it is pressed down into the interior of the guide collar.

[0017] Preferably, the dual-form positioning component includes a column mounted on a support base, a mounting plate slidably sleeved on the column, an inclined long plate mounted on one end of the mounting plate, and a short plate inclined in the same direction as the long plate mounted on the other side of the mounting plate. When the long plate faces inward, it clamps and positions the flask, and when the short plate faces inward, it clamps and positions the culture plate.

[0018] A limiting mechanism is provided on the column to restrict the movement of the mounting plate, so as to keep the mounting plate stable and use the long or short plate to provide a positioning function.

[0019] Preferably, the limiting mechanism includes a rotating shaft three that is mounted through the column. The rotating shaft three is rotatably connected to the column, and cams are installed at both ends of the rotating shaft three. A handle is installed on the cam, and the handle is used to rotate the cam, and the cam is used to press against the mounting plate to limit the movement of the mounting plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Unlike existing technologies, when using a biological shaker for cell culture, the appropriate clamping shape can be selected according to the type of culture container, thereby providing effective shaking positioning for the culture container and ensuring stable and efficient shaking culture.

[0022] Furthermore, during container placement and positioning, the top plate can be raised and lowered simultaneously to position all containers on the top plate or cancel their positioning. This eliminates the need for laborious flask clamp expansion for positioning each container. Simply place the containers into their corresponding clamps and raise and lower the top plate, saving time and effort and making it convenient and practical. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figure 1-14 The present invention provides a technical solution: a shaker for a biochemistry laboratory, comprising a main body 1 and a bed surface 11 mounted on the main body 1. The main body 1 and the bed surface 11 constitute the shaker structure of the prior art, and both the bed surface 11 and the main body 1 are prior art. The main body 1 mainly includes all the structures of the prior art shaker except for the bed surface 11 and the clamping part, and provides the function of a shaker.

[0042] Furthermore, a base plate 12 is detachably installed on the bed surface 11, which can be detachably installed by means of bolts, and a top plate 13 that can be vertically lifted is provided on the base plate 12;

[0043] As a technical means, a screw 14 is threaded through the top plate 13, the bottom end of the screw 14 is rotatably connected to the bottom plate 12, and a grip 15 is installed on the top plate 13. In this embodiment, the grip 15 is preferably an anti-slip knob 18, so that it is convenient to grip the screw 14 and rotate it. When the screw 14 is rotated, the top plate 13 can be driven to move vertically up and down accordingly.

[0044] Furthermore, at least four screws 14 are provided, and they are respectively located at the four corners of the top plate 13. This design makes the driving and lifting of the top plate 13 more stable and labor-saving. A sprocket 16 is installed on the outside of each screw 14, and a chain 17 is provided on the outside of the sprocket 16. The four sprockets 16 move synchronously with the chain 17, so that the four screws 14 rotate synchronously. In this way, multiple screws 14 can be rotated at the same time to effectively facilitate the lifting and lowering of the top plate 13.

[0045] Furthermore, guide rollers 19 are installed on the top plate 13 at positions between adjacent screws 14. The chain 17 runs around the inside of each guide roller 19. The design of the guide rollers 19 is used to change the trajectory of the chain 17 so that it can wrap around each sprocket 16 with a sufficient wrap angle, thereby ensuring that each sprocket 16 rotates stably and synchronously through the chain 17.

[0046] In addition, multiple clamping drive mechanisms 2 are evenly arranged between the top plate 13 and the bottom plate 12. As a technical means, multiple through slots 21 are opened on the top plate 13. The clamping drive mechanism 2 includes a rotating shaft 22 installed in the through slot 21 respectively, and a bearing seat 23 is installed on the rotating shaft 22.

[0047] It also includes a rotating shaft 24 installed at the bottom of the top plate 13, a driving collar 25 is provided on the rotating shaft 24, and a top moving member 26 is provided between the driving collar 25 and the bearing seat 23. As a technical means, the bearing seat 23 is a cylindrical structure, and a spiral groove 261 is provided on the side of the bearing seat 23. The top moving member 26 includes a top post 262 installed on the driving collar 25. The top end of the top post 262 extends into the spiral groove 261 and is slidably connected to its inner wall so as to drive the bearing seat 23 to deflect when the driving collar 25 rotates.

[0048] A guide collar 27 is provided on the base plate 12 at the position corresponding to the drive collar 25. Both the drive collar 25 and the guide collar 27 are annular structures. A second actuating member 28 is provided between the drive collar 25 and the guide collar 27. As a technical means, the second actuating member 28 includes a second actuating post 281 installed on the inner wall of the guide collar 27, and a second spiral groove 282 is opened on the outer side of the drive collar 25. The second actuating post 281 extends into the second spiral groove 282 and is slidably connected to its inner wall so as to drive the drive collar 25 to rotate when it is pressed into the guide collar 27, so as to ensure that the drive collar 25 drives the bearing seat 23 to deflect and clamp.

[0049] Finally, a dual-form positioning component 3 capable of simultaneously adapting to flasks and culture dishes is provided on the clamping drive mechanism 2. As a technical means, the dual-form positioning component 3 includes a column 31 mounted on the support base 23, a mounting plate 32 slidably sleeved on the column 31, an inclined long plate 33 mounted on one end of the mounting plate 32, and a short plate 34 inclined in the same direction as the long plate 33 mounted on the other side of the mounting plate 32. When the long plate 33 faces inward, it clamps and positions the flask, and when the short plate 34 faces inward, it clamps and positions the culture dish.

[0050] A limiting mechanism 35 is provided on the column 31 to restrict the movement of the mounting plate 32, so as to keep the mounting plate 32 stable and use the long plate 33 or the short plate 34 to provide positioning.

[0051] The limiting mechanism 35 includes a rotating shaft 351 that is mounted through the column 31. The rotating shaft 351 is rotatably connected to the column 31. A cam 352 is installed at both ends of the rotating shaft 351, and a handle 353 is installed on the cam 352. The handle 353 is used to rotate the cam 352, and the cam 352 is used to press against the mounting plate 32 to limit the movement of the mounting plate 32. This ensures that the long plate 33 or the short plate 34 is stably positioned.

[0052] In this embodiment, whether it is a conical bottle or a flat open container, before positioning, the gripper 15 is used to set the top plate 13 to move longitudinally, so as to drive the support seat 23 to drive the corresponding long plate 33 or short plate 34 to deflect outward, so as to open all the dual-form positioning members 3 and keep them in the unpositioned state. Then, the conical bottle or flat open container is placed in the middle of each dual-form positioning member 3, and then the gripper 15 is set to drive the top plate 13 to reset. Then, during the reset process of the top plate 13, each dual-form positioning member 3 gathers together and contacts the container for positioning.

[0053] It should be noted that both the long plate 33 and the short plate 34 are elastic springs, which can stably clamp the container after contact with it and when the bearing seat 23 continues to deflect, and effectively prevent damage to the container.

[0054] Furthermore, when it is necessary to select the long plate 33 or the short plate 34 according to the type of container, the contact positioning of the mounting plate 32 can be canceled by rotating the cam 352 with the handle 353, and the mounting plate 32 can be rotated to turn the corresponding long plate 33 or short plate 34 to the inside, and the handle 353 can be reset to the contact positioning.

[0055] Example 2

[0056] See Figure 15 As shown, based on Embodiment 1, but different from Embodiment 1, in this embodiment, the present invention provides another implementation of the grip 15: the grip 15 includes a vertical rod 151 installed at the top of the screw 14, a movable shaft 152 slidingly passing through the vertical rod 151, and a protruding edge 153 with a diameter larger than the movable shaft 152 is provided at both ends of the movable shaft 152. In this embodiment, the movable shaft 152, which can be pulled left and right, is used to form a lever structure. By using this method of increasing the lever arm, it is easier to turn the screw 14.
