Description

Technical Field

[0001] This utility model relates to the field of chemical experimental oscillation extraction technology, and in particular to a light-shielding oscillation device. Background Technology

[0002] The statements in this section merely provide background information related to this utility model and do not necessarily constitute prior art.

[0003] Oscillators provide stable rotational frequency and oscillation amplitude, ensuring uniform mixing and reaction of experimental samples. They are mainly used in research and production in scientific fields such as microbiology, medicine, pharmaceuticals, environmental protection, food, and animal husbandry. Currently, the design of traditional oscillators is usually optimized for standardized containers (such as test tubes, microplates, and petri dishes). However, with the diversification of experimental sample containers, the clamping structures in existing technologies are gradually revealing their limitations.

[0004] Currently, most shakers use fixed clamps to hold containers, such as spring clips, snap-on clamps, or bolt-on clamps. These clamps have fixed shapes, sizes, and clamping angles, and are only suitable for cylindrical containers of specific diameters. For square, conical (e.g., Erlenmeyer flasks), or other irregularly shaped containers (e.g., headspace vials, volumetric flasks, centrifuge tubes), the lack of a suitable clamp can lead to insecure clamping, resulting in sample leakage and affecting the shaking effect. Furthermore, generally, one clamp is used to hold one container; designing shakers suitable for multiple containers increases structural complexity and size. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a light-shielding oscillation device. The device uses a movable, integrated light-shielding cover and an elastic limiting base plate to create a space for placing containers. This makes the containers that can be used with the oscillator not limited to a specific shape, thus making it more versatile. Compared to a clamp-type fixed structure, it can hold more containers.

[0006] The present invention adopts the following technical solution: A light-shielding oscillation device includes an oscillation table, a limiting base plate, a pressing structure, and a light-shielding cover. The limiting base plate is placed at the bottom of the oscillation table. The limiting base plate includes a plate body with several sample limiting grooves. The upper surface of the plate body is covered with a soft pad. A light-shielding cover parallel to the limiting base plate is placed above the limiting base plate. There is a placement space between the light-shielding cover and the limiting base plate. A container to be oscillated is placed inside the placement space, with the bottom of the container placed in the sample limiting groove. The pressing structure is set on both sides of the light-shielding cover, and the height of the light-shielding cover is adjusted by the pressing structure.

[0007] Furthermore, a soft sealing gasket is provided at the bottom of the light-proof cap, and the soft sealing gasket is made to abut against the mouth of the container by adjusting the height of the light-proof cap.

[0008] Furthermore, the soft sealing gasket is a rubber gasket or a silicone gasket.

[0009] Furthermore, it also includes a base, on which the oscillation table is placed.

[0010] Furthermore, a handle is provided on the top of the light-blocking cover.

[0011] Furthermore, the oscillation table is made of a non-transparent material.

[0012] Furthermore, the clamping mechanism includes an L-shaped seat located on the side of the oscillating table. The L-shaped seat is rotatably connected to a threaded seat and is equipped with an adjusting bolt that is compatible with the internal thread of the threaded seat. The bottom of the adjusting bolt is detachably abutted against the light-shielding cover.

[0013] Furthermore, the limiting base plate also includes a plate pull tab, which is disposed on the side of the plate.

[0014] Furthermore, the soft pad covers the entire upper surface of the board and is bonded to the upper surface of the board with an adhesive.

[0015] Furthermore, multiple suction cups are installed on the soft pad at the bottom of the sample limiting groove, and the bottom of the container contacts the suction cups.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a light-shielding oscillation device that presses the top and bottom of a sample container and protects the container with a flexible pad. This utility model device is no longer limited to the container shape for targeted clamp design. The top and bottom pressing clamping design can be used for sample containers of various shapes, better stabilizing the sample container and avoiding sample leakage that would affect the oscillation effect.

[0017] This invention features elastic and flexible contact between the upper and lower contact surfaces of the container, increasing stability while preventing bottle breakage due to excessive pressure. The shaking table is made of opaque material and uses a light-shielding cover as the top plate, making it suitable for shaking samples requiring light protection. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Terminology Explanation: The terms "installation", "connection", "linking", and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction relationship between two components. For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0022] Example This utility model, based on existing technology, proposes a light-shielding oscillation device to solve the technical problems in the background art, such as... Figure 1 As shown, the system includes a base 1, an oscillation table 2, a limiting base plate, a clamping structure, and a light-shielding cover 6. The oscillation table 2 is placed on the base 1. The limiting base plate is placed at the bottom of the oscillation table 2. The limiting base plate includes a plate body 3, which has several sample limiting grooves 4. The upper surface of the plate body 3 is covered with a soft pad. A light-shielding cover 6, parallel to the limiting base plate, is placed above the limiting base plate. There is a placement space 8 between the light-shielding cover 6 and the limiting base plate. The container 13 to be oscillated is placed inside the placement space 8, and the bottom of the container 13 is placed in the sample limiting grooves 4. The clamping structure is set on both sides of the light-shielding cover 6, and the height of the light-shielding cover is adjusted by the clamping structure.

[0023] In one specific embodiment, the oscillation table 2 is a box-type oscillation table. The oscillation table 2 is made of a non-transparent material. Both the light-shielding cover and the box-type oscillation table are made of non-transparent materials such as metal (e.g., stainless steel).

[0024] In practical use, if the sample does not need to be protected from light, it can also be used as a light-proof cover made of non-light-proof material to ensure visibility.

[0025] In one specific embodiment, the length of the light-shielding cover is slightly less than the distance between the left and right sides of the shaking table, and the width is slightly less than the distance between the front and back sides of the shaking table, allowing it to be placed inside the shaking table. A soft sealing gasket 7 is provided at the bottom of the light-shielding cover. The size of the soft sealing gasket 7 is the same as the lower surface of the light-shielding cover. The height of the light-shielding cover is adjusted so that the soft sealing gasket abuts against the mouth of the container. The soft sealing gasket is a rubber gasket or a silicone gasket. A lid handle 9 is provided at the top of the light-shielding cover. When the bolt connection is not adjusted, the light-shielding cover can be removed by pulling the lid handle 9. After the light-shielding cover is closed, the soft sealing gasket abuts against the top of the container. The rubber or silicone gasket is soft and will not damage the sample container.

[0026] In one specific embodiment, two clamping mechanisms are symmetrically arranged to stably clamp both ends of the light-shielding cover. The clamping mechanisms are detachably connected to the light-shielding cover. Each clamping mechanism includes an L-shaped seat 10 located on the side of the oscillating table. The L-shaped seat 10 is rotatably connected to a threaded seat 11 via a pin. An adjusting bolt 12, adapted to the internal thread of the threaded seat 11, is provided. The bottom of the adjusting bolt 12 detachably abuts against the light-shielding cover. After the light-shielding cover is placed, the adjusting bolt is tightened so that the bottom of the adjusting bolt abuts against and clamps the light-shielding cover.

[0027] In one specific embodiment, the limiting base plate includes a plate body and a plate body pull tab 5 that are movably placed inside a box-type vibration table. The plate body pull tab 5 is disposed on the side of the plate body, such as... Figure 2 As shown. In use, the plate can be removed by pulling the plate pull tab 5. A limiting protrusion 14 is provided on the side wall of the limiting base plate, and a corresponding groove is provided on the inner side wall of the oscillation table. The engagement of the limiting protrusion 14 and the groove makes the limiting base plate more stable. In use, the limiting base plate is placed inside the box-type oscillation table, and the limiting base plate is pressed down, causing the limiting protrusion to engage with the limiting groove. The plate can be removed by pulling the plate pull tab upwards. The limiting protrusion has smooth edges and a gentle protrusion, making it easy to lift the plate when pulling the plate pull tab without getting stuck.

[0028] In one specific embodiment, the soft pad completely covers the upper surface of the plate and is bonded to the upper surface of the plate by an adhesive, wherein the adhesive can be glue. Multiple suction cups are provided on the soft pad at the bottom of the sample positioning groove, and the bottom of the container contacts the suction cups. The sample positioning groove is processed into a bowl shape, which not only accommodates the container but also provides a "self-centering" effect, allowing the container to automatically slide to the center position during placement. The sample positioning groove uses rigid plastic or polypropylene to provide an installation base for the inner silicone soft pad. The soft pad is made of highly elastic, high-friction coefficient medical-grade or food-grade silicone rubber, and the silicone soft pad is made into a single inner liner, completely covering the inner surface of the groove, and fixed to the side or lower surface of the plate by edge flanges. A stabilizing structure is provided at the bottom of the sample positioning groove, with densely arranged miniature, flexible dome-shaped suction cup structures on the bottom contact surface of the silicone soft pad. The suction cups are approximately 2mm in diameter, and the top surface of the suction cup structure (i.e., the side in contact with the container) is made with microscopic textured patterns to further increase friction. When the container is placed into the sample limiting groove, it slides to the center of the sample limiting groove through the bowl-shaped inner surface. During the pressing down of the light-proof cover, the suction cup adheres to the bottom of the container, thereby further fixing the container.

[0029] It should be noted that since the limiting base plate of this application is removable, other types of limiting base plates can be designed for replacement, as long as the plate body is compatible with the shaking table. The plate body is provided with a soft-contact sample limiting groove 4. The container is placed inside the sample limiting groove, and it is suitable for containers with round, square, triangular, or other geometric shapes. In use, place the container in the sample limiting groove, cover it with the light-proof cap, and tighten the adjusting bolt. The bottom of the adjusting bolt abuts against and presses the light-proof cap, pressing the top and bottom of the container tightly. The suction cup adheres to the bottom of the container, and then the horizontal shaker is started for shaking.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
