Description

Technical Field

[0001] This utility model belongs to the technical field of chemical and biological experimental equipment, specifically relating to an adjustable shaker fixing device. Background Technology

[0002] A laboratory shaker is a commonly used laboratory device that can mix and culture experimental samples through mechanical vibration or rotation. It is widely used in fields such as chemistry, biochemistry, microbiology, cell biology, molecular biology, and drug development.

[0003] To prevent sample containers from falling or being bumped during shaking, researchers typically secure them to a shaker. Currently, shakers are equipped with various securing devices, including spring clamps, spring nets, and adhesive plates. However, due to the diverse types of sample containers used in laboratory research, varying greatly in shape, size, and height, there is currently no single securing device that can stably hold all these different sample containers in place.

[0004] Existing shaking insulator fixing devices all have some defects or are inconvenient to use. The spring clamps that are widely used in laboratory shaking insulators are fixed in position and only suitable for a fixed type of conical flask, which is not very versatile.

[0005] For example, spring mesh is used to place containers of a certain size on a shaker through spring mesh. The containers can be clamped and fixed by the deformable springs, which is highly flexible in use. However, it is limited by the size of the spring mesh and the elasticity of the spring. Containers with a cross-section smaller than the mesh size cannot be fixed, while containers with a cross-section much larger than the mesh size are easily squeezed by the spring. Therefore, spring mesh cannot be adapted to fix containers of different specifications and types.

[0006] For example, with movable clamps, the fixing rods can only be set horizontally along a single radial direction, and only containers with similar diameters can be fixed between two fixing rods at the same time, resulting in low flexibility in use.

[0007] Chinese patent CN222389812U discloses a shaking incubator that uses connecting frames and docking frames with arc-shaped frames of different sizes to simultaneously fix sample containers of different diameters. However, the shape of the fixed containers must be similar to the shape of the arc-shaped frames, and the number of containers must be at most the same as the number of corresponding arc-shaped frames, resulting in a waste of space on the shaker.

[0008] Chinese patent CN203764187U discloses a fixing device for an adjustable horizontal shaker, including multiple elastic cables and a rectangular frame. The rectangular frame is equipped with pressure rods for holding the elastic cables in place, allowing for free adjustment of the spacing between the cables to accommodate sample containers of different sizes. However, due to their elastic properties, the elastic cables tend to have limited length variation, making installation laborious and prone to elastic attenuation due to excessive stretching. Furthermore, the elastic cables fix the sample container at a fixed height, making them unsuitable for sample containers of varying heights.

[0009] Therefore, how to provide a shaker fixing device that is highly flexible, easy to use, and capable of stably fixing different numbers of sample containers on a shaker is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] In view of this, the present invention provides an adjustable shaker fixing device that can clamp and fix multiple different types of sample containers, which is highly flexible and easy to use.

[0011] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable shaking table fixing device, comprising:

[0012] Support members for connecting the laboratory shaker base plate, a plurality of said support members being vertically distributed along the peripheral edge of the laboratory shaker base plate and being detachably connected to the laboratory shaker base plate;

[0013] A telescopic support frame, wherein the telescopic support frame is detachably connected to the plurality of support members in a variable position;

[0014] A telescopic rod is provided, at least one telescopic rod is provided, and both ends of the telescopic rod are connected to the telescopic support frame and / or the support member. The telescopic rod cooperates with the telescopic support frame and / or the support member to constrain the sample container to be fixed.

[0015] The technical advantages of this invention are as follows: the support member is detachably connected to the laboratory shaker base plate, and its height can be adjusted accordingly. This allows the fixed position of the telescopic rod to change not only in the direction horizontal to the laboratory shaker base plate but also in the direction perpendicular to the laboratory shaker base plate. The telescopic rod can be adjusted in length to change its connection position on the telescopic support frame and / or support member, thereby achieving the clamping and fixing of sample containers of different models and shapes. The telescopic rod can reasonably change its connection position on the telescopic support frame and / or support member according to different container types, improving the flexibility of the device. In specific implementation, one or more telescopic rods can be used to fix sample containers of different sizes, effectively improving the efficiency of the shaker and enhancing the convenience and safety of using the shaker for different experimental needs.

[0016] Preferably, the retractable support frame includes multiple sets of insertion tubes and multiple sets of stoppers. The multiple sets of insertion tubes and multiple sets of stoppers overlap and nest with each other to form a rectangular frame structure with a variable area. The minimum size of the rectangular frame structure is equal to the outer contour size of the laboratory shaker seat plate.

[0017] The resulting technical effect is that the telescopic support frame is composed of multiple sets of inserted tubes and multiple sets of plug rods that overlap and nest. By changing the overlapping position, the size of the telescopic support frame can be adjusted, thereby adapting to changes in the height of the support and further providing a basis for changes in the vertical direction of the telescopic rods, thus improving the applicability of the telescopic support frame.

[0018] Preferably, a transition connector is provided between the support member and the retractable support frame. The transition connector includes a first connecting part, a second connecting part, and a rotating shaft connecting the first connecting part and the second connecting part. The first connecting part is detachably connected to the support member, and the second connecting part is detachably connected to the retractable support frame. The second connecting part rotates based on the rotating shaft in the vertical plane where the peripheral edge of the laboratory shaker seat plate is located, thereby adjusting the angle between the plane where the retractable support frame is located and the plane where the laboratory shaker seat plate is located.

[0019] The resulting technical effect is that the transition connector can connect the support and the telescopic support frame. It should be noted that the second connection can rotate on the vertical plane where the periphery of the laboratory shaker seat plate is located, based on the pivot. This can change the angle between the first and second connections, thereby changing the connection angle between the support and the telescopic support frame. This facilitates subsequent angle adjustment of the telescopic support frame, thus adapting to changes in the height of the support. According to the fixation requirements of the sample container, the transition connector can be reasonably connected to the appropriate position of the support and the telescopic support frame.

[0020] Preferably, the first connecting part is a hoop-type structure or a strip-type structure that connects with the support member, and the second connecting part is a sleeve structure that connects with the telescopic support frame.

[0021] The resulting technical effect is that, since the retractable support frame and the support components may have different structural types, corresponding connecting parts are required for connection. When the first connecting part is a hoop plate, it can connect rod-type support components; when the first connecting part is a strip plate, it can connect plate-shaped support components. The tube sleeve structure can be directly nested with the retractable support frame, and the retractable support frame can rotate under the constraint of the tube sleeve structure, ensuring the adjustment of the angle between the plane where the retractable support frame is located and the plane where the laboratory shaker seat plate is located.

[0022] Preferably, both ends of the telescopic rod are connected to a ball joint, which includes a ball seat, a ball pin, and a connector. The ball seat is fixedly connected to the end of the telescopic rod, and the ball pin is movably connected to the ball seat, so that the telescopic rod moves within the axial extension direction of the outer periphery of the ball pin under the action of the ball seat. The connector is fixedly connected to the ball pin and is used to connect the support member or the telescopic support frame.

[0023] The resulting technical effect is that the telescopic rods are connected to the telescopic support frame or support through ball joints, which allows for a certain amount of angle variation. This avoids interference between multiple telescopic rods on the horizontal plane and allows for angle adjustment of the telescopic rods at different positions on the telescopic support frame or support as needed, thereby constraining the sample container at different angles.

[0024] Preferably, the connector is a bolt structure or a spring clamp.

[0025] The resulting technical effect is that the connector can be connected to perforated plates using bolts and nuts, or to telescopic support frames or rod-type support components using spring clamps, offering diverse forms and high flexibility.

[0026] Preferably, the support member is a single rod, a rod assembly, or a perforated plate, and the support member is detachably connected to the laboratory shaker base plate by bolts.

[0027] The resulting technical effects are: the support structure can take various forms, including single rods, rod assemblies, or perforated plates; the support provides different positions for the telescopic rods, especially for connecting bases at different positions perpendicular to the seat plate; the height of the support can be adjusted by bolts, further increasing the flexibility of the telescopic rods in constraining the sample container; this device constructs constraints for different types of sample containers by connecting the telescopic rods at different positions on the telescopic support frame and / or support.

[0028] Preferably, the rod assembly is a star-shaped structure or a mesh frame structure, and the holes on the perforated plate are strip holes.

[0029] The resulting technical effect is that the rod assembly has a variety of structural types. In specific implementation, it is not limited to the star-shaped structure or the mesh frame structure. Its purpose is to provide a connection base for telescopic rods at different positions. Similarly, perforated plates can also provide a connection base for telescopic rods at different positions. The shape of the perforation is diverse, including straight, star-shaped, and mesh frame.

[0030] Preferably, it also includes a perforated plate frame, the side of which has a groove that mates with the telescopic rod or the telescopic support frame.

[0031] The resulting technical effect is that, in addition to directly constraining the sample container, the telescopic rod can also clamp the perforated plate frame, on which the sample container is mounted, thus improving the flexibility of the device. The grooves in the perforated plate frame also improve the stability of the positioning and clamping. Attached Figure Description

Detailed Implementation

[0048] 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.

[0049] See appendix to this utility model Figures 1 to 9 This utility model discloses an adjustable shaking table fixing device, which includes:

[0050] Support members 1 are used to connect the laboratory shaker base plate 7. Multiple support members 1 are vertically distributed on the periphery of the laboratory shaker base plate 7 and are detachably connected to the laboratory shaker base plate 7. The purpose is to realize the adjustment of the connection position.

[0051] The retractable support frame 2 and the support member 1 are detachable and can be positioned in a variable manner. In specific use, the angle between the plane of the retractable support frame 2 and the plane of the laboratory shaker seat plate 7 can be varied according to the fixing requirements.

[0052] Telescopic rod 3, with both ends connected to the telescopic support frame 2 and / or support member 1, the telescopic rod 3 cooperates with the telescopic support frame 2 and / or support member 1 to constrain the sample container to be fixed, and the number of sample containers to be fixed is determined as needed, with at least one telescopic rod 3.

[0053] Specifically, the telescopic support frame 2 is composed of multiple sets of insert tubes 21 and multiple sets of plug rods 22 nested together, and its size can be adjusted by changing the overlapping position.

[0054] More specifically, the retractable support frame 2 includes two right-angle insertion tubes 21 and two right-angle plug rods 22. The two ends of the right-angle plug rods 22 are inserted into one end of the two right-angle insertion tubes 21 in sequence, and the two ends of the other right-angle plug rod 22 are inserted into the remaining ends of the two right-angle insertion tubes 21. The two right-angle insertion tubes 21 and the two right-angle plug rods 22 overlap and nest with each other to form a rectangular frame structure with a variable area. That is, the retractable support frame 2 structure with different sizes can be obtained according to the different overlapping positions of the right-angle insertion tubes 21 and the right-angle plug rods 22, which can adapt to the height change of the support member 1. The minimum size of the retractable support frame 2 is equal to the outer contour size of the laboratory shaker seat plate 7.

[0055] It should be noted that there is a transition connector 4 between the support member 1 and the telescopic support frame 2. The transition connector 4 can change the relative angle between the plane of the telescopic support frame 2 and the plane of the laboratory shaker seat plate 7. The transition connector 4 includes a first connecting part 41 for connecting the support member 1 and a second connecting part 42 for connecting the telescopic support frame 2. The first connecting part 41 and the second connecting part 42 can rotate relative to each other through the pivot 43 between them.

[0056] Both ends of the telescopic rod 3 are fixed with ball joints 5 for connecting the support member 1 or the telescopic support frame 2, thereby realizing the connection relationship between the telescopic rod 3 and the telescopic support frame 2 or the support member 1. The ball joint 5 includes a ball seat 51, a ball pin 52 and a connector 53. The ball seat 51 is fixedly connected to the end of the telescopic rod 3, and the ball pin 52 is movably connected to the ball seat 51, so that the telescopic rod 3 moves within the axial extension direction of the outer periphery of the ball pin 52 under the drive of the ball seat 51. The connector 53 is fixedly connected to the ball pin 52 and is used to connect the support member 1 or the telescopic support frame 2. The movable connection between the support frame 2, ball seat 51, and ball pin 52 is the basis for the telescopic rod 3 to be fixed in different positions and directions. Driven by the ball seat 51, the telescopic rod 3 moves along the axial extension direction of the outer periphery of the ball pin 52, allowing it to move not only horizontally (same as the laboratory shaker seat 7) but also vertically. Its maximum range of rotation is the extension range of the outer periphery of the ball pin 52, and it can also rotate within this range. After determining the angle and position, it is fixed to the support member 1 or the telescopic support frame 2 via the connector 53. The connector 53 can be of different types, at least a spring clamp or a bolt structure, and can be reasonably determined according to the needs of different types of fixed objects.

[0057] Support component 1 has various structural forms, including single rods, rod assemblies, or perforated plates. Rod assemblies can be star-shaped or grid-frame structures, and the holes on the perforated plates can be strip-shaped holes. The specific connection methods between support component 1 and the laboratory shaker base plate 7 vary depending on the structural form of support component 1.

[0058] Application Example 1

[0059] Reference Appendix Figure 10 The support member 1 is a rod. The bottom end of the support member 1 is connected to the laboratory shaker base plate 7 by bolts and nuts. The telescopic support frame 2 is connected to the top end of the support member 1. The plane on which the telescopic support frame 2 is located is a horizontal plane. At this time, the size of the telescopic support frame 2 is consistent with the laboratory shaker base plate 7. Four telescopic rods 3 are selected. The ends of the four telescopic rods 3 are ball joints 5 with spring clamps. The four telescopic rods 3 are all connected to the telescopic support frame 2 to fix a conical sample container.

[0060] Application Example 2

[0061] Reference Appendix Figure 11 Unlike Example 1, it is necessary to fix two more sample containers of different sizes on the basis of fixing one sample container. Select a position where the gap between the telescopic rod 3 and the telescopic support frame 2 is similar to the size of the container, and add another telescopic rod 3. This way, together with the existing telescopic rod 3, multiple sample containers of different sizes can be fixed. The sample containers can be conical flasks, wide-mouth bottles, or other types of containers.

[0062] Application Example 3

[0063] Reference Appendix Figure 12 Unlike Example 2, Example 3 only requires one telescopic rod 3 to fix multiple sample containers of different sizes. The telescopic rod 3 can be tilted and constrained on one side of three different sample containers, and together with the telescopic support frame 2, it can complete the fixation of them.

[0064] Application Example 4

[0065] Reference Appendix Figure 13 Based on Example 3, a small sample container is added for fixing. This allows the height of the retractable support frame 2 on the side of the laboratory shaker base 7 where the sample container is not fixed to be lowered to accommodate the height of the small sample container. Since both the retractable support frame 2 and the support member 1 are rod structures, the first connecting part 41 of the matching transition connector 4 is a hoop, and the second connecting part 42 is a sleeve. A pivot 43 connects the first connecting part 41 and the second connecting part 42, allowing the hoop and the sleeve to rotate relative to each other. This accommodates the height deformation of the retractable support frame 2 and the support member 1. During adjustment, the hoops connected to the support member 1 on the side to be lowered and the adjacent sides can be loosened. The hoop on the side to be lowered can be adjusted to a position slightly lower than the height of the target small sample container and then fixed. Since the height of the hoops on the adjacent support members 1 decreases to varying degrees due to the retractable support frame 2, all hoops can be tightened and re-fixed. At this time, the telescopic support frame 2 has a certain tilt angle relative to the laboratory shaker seat plate 7. The telescopic rod 3 can be used to clamp the target small sample container in the corner at the lower tilt end, so that multiple sample containers with large height differences can be fixed at the same time.

[0066] Application Example 5

[0067] Reference Appendix Figure 14 Unlike embodiments 1-4, in this embodiment, the telescopic rod 3 does not need to directly contact the sample container. Instead, two telescopic rods 3 are used to clamp the perforated plate frame 6, and multiple sample containers are placed on the perforated plate frame 6. The two telescopic rods 3 can be arranged in parallel, which can easily and quickly fix small sample containers.

[0068] Application Example 6

[0069] Reference Appendix Figure 15 Unlike the above embodiments, the support member 1 is a perforated plate, which is connected to the laboratory shaker base plate 7 by bolts and nuts. Its height can be adjusted by fixing the bolts within the holes in the perforated plate. It should also be noted that because the support member 1 is a perforated plate, the transition connector 4 between the support member 1 and the telescopic support frame 2 needs to be changed. The first connecting part 41 is a strip plate, fixed to the top edge of the perforated plate by screws or bolts. Furthermore, the connection method between the ball joint 5 at the end of the telescopic rod 3 and the perforated plate support member 1 is different from the connection method with the rod support member 1. The ball pin 52 of the ball joint 5 is connected to a connector 53 for connecting the support member 1 or the telescopic support frame 2. The ball seat 51 is fixedly connected to the end of the telescopic rod 3, and the ball pin 52 is movable to the ball seat 51. The connection allows the telescopic rod 3 to move within the axial extension direction of the outer periphery of the ball pin 52 under the drive of the ball seat 51. The connector 53 is fixedly connected to the ball pin 52 and is used to connect the support member 1 or the telescopic support frame 2. The movable connection between the ball seat 51 and the ball pin 52 is the basis for the telescopic rod 3 to be fixed in different positions and directions. The telescopic rod 3 moves along the axial extension direction of the outer periphery of the ball pin 52 under the drive of the ball seat 51, so that the telescopic rod 3 can move not only in the same horizontal direction as the laboratory shaker seat plate 7, but also in its vertical direction. The maximum range of rotation of the telescopic rod 3 is the extension range of the outer periphery of the ball pin 52. Of course, it can also rotate within this range, so that the telescopic rod 3 is parallel to the plane of the square structure enclosed by the telescopic support frame 2. After determining the angle and position, it is fixed to the support member 1 or the telescopic support frame 2 through the connector 53. Specifically, when connecting perforated plates, connector 53 is a bolt structure, which is connected to the perforated plates by bolts and nuts. When connecting rods, connector 53 is a spring clamp, which is connected to the rods by spring clamps.

[0070] Example 6 uses four telescopic rods (3 pieces) to clamp a row of sample containers of the same specifications. The connectors 53 of two telescopic rods 3 are horizontally fixed in the gap between the telescopic support frame 2 and the perforated plate. The connectors 53 of the other two telescopic rods 3 are horizontally arranged in the slots of the perforated plate. The slots on the perforated plate are in a star shape.

[0071] In addition, the perforations on the perforated plate can be either frame-shaped or straight-line shaped; please refer to the appendix for details. Figure 7 .

[0072] Figure 7 A represents a single-member type. Figure 7 B represents a cross-shaped composite member type. Figure 7 C represents a grid-frame composite member type. Figure 7 D is a perforated plate with a 1-shaped slot. Figure 7 E is a perforated plate with a star-shaped perforation pattern. Figure 7 F is a perforated plate with a mesh-like grid pattern.

[0073] This device, through its telescopic rod 3 with telescopic function, adjustable support 1, and telescopic support frame 2, allows for flexible adjustment of the position of the telescopic rod 3 in both horizontal and vertical directions relative to the laboratory shaker base plate 7. This facilitates convenient and flexible fixing of sample containers of different sizes, without limiting the number of sample containers of different sizes, making it suitable for complex and diverse experimental needs.

[0074] The telescopic rod 3 mentioned in this device is a multi-section telescopic rod. The ends of the multi-section telescopic rod have flanges for limiting separation. The sections of the telescopic rod can be reinforced with threaded clips to limit the telescopic length, similar to the telescopic handle adjustment of a broom or mop. This is an existing method and will not be elaborated upon here. Alternatively, it can be fixed using multiple slots and elastic snaps. Compared to the traditional elastic cable adjustment method, the telescopic rod has a wider length adjustment range, requires no strenuous stretching during adjustment and installation, and provides stable telescopic performance, making it suitable for large shaking tables.

[0075] To improve the clamping effect on the sample container, friction material or buffer material, such as rubber or sponge, is provided on the outer surface of each section of the telescopic rod 3. This increases the contact area and friction between the telescopic rod 3 and the sample container, improves the fixing strength, and avoids damage from impacts.

[0076] When in use, this device can be based on the telescopic rod 3 and connected to other fixing devices to further expand the flexibility and functionality of the fixing device. As shown in application embodiment 5, the telescopic rod 3 can be used to clamp perforated plate racks 6 such as EP tube racks or centrifuge tube racks with corresponding recesses, which can conveniently and effectively fix multiple small sample containers at the same time. Some special clamps for sample containers, such as test tube clamps, can also be set based on the telescopic rod 3.

[0077] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0078] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
