Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, specifically a reaction cup assembly. Background Technology

[0002] Reaction cups are commonly used laboratory instruments in biological, chemical, and other experimental fields, as well as in related detection and analysis work. Currently, most reaction cups on the market are elongated in shape, and some even have a round bottom design. While this shape design meets the specific requirements of experiments for reaction space and conditions to a certain extent, it also brings many inconveniences in use.

[0003] Due to their slender shape and small bottom area, especially the round-bottom design, reaction cups are extremely unstable when placed on ordinary tabletops. They easily tip over with the slightest touch, potentially causing reagent spillage, wasting experimental materials, interrupting experiments, contaminating the experimental environment, and even injuring personnel. To ensure stable and convenient placement of reaction cups, prevent tipping during experiments, and avoid disrupting the experimental process, we propose a reaction cup assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a reaction cup assembly that can stably and conveniently place the reaction cup, preventing it from tipping over during the experiment and avoiding any impact on the experimental process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reaction cup assembly includes a base plate, a plurality of support rods fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the support rods, a limit ring fixedly connected to the top of the top plate, a placement hole provided on the top plate, a reaction cup placed in the placement hole, an installation cylinder fixedly connected to the top of the base plate, a sliding cylinder slidably connected to the inner wall of the installation cylinder, the top of the sliding cylinder abutting against the bottom of the reaction cup, a spring fixedly connected to the top of the inner cavity of the sliding cylinder, and the bottom of the spring fixedly connected to the top of the base plate.

[0007] Preferably, the top plate is slidably connected to two sets of sliding plates at its bottom, a support plate is fixedly connected to the bottom of the sliding plates, and an arc-shaped plate is fixedly connected to the bottom of the support plate. The side of the arc-shaped plate closest to the reaction cup abuts against the reaction cup.

[0008] Preferably, a sleeve is slidably fitted onto the support rod, and a connecting plate is fixedly connected between the two sets of sleeves. A movable plate is fixedly connected to the side of the arc-shaped plate near the connecting plate. A sliding opening is provided on the movable plate. A fixing block matching the sliding opening is fixedly connected to the side of the mounting cylinder near the movable plate. The fixing block is slidably connected to the sliding opening, and the sliding opening is inclined.

[0009] Preferably, an L-shaped rod is fixedly connected to the bottom of the connecting plate, and one end of the L-shaped rod near the sliding cylinder is fixedly connected to the outside of the sliding cylinder.

[0010] Preferably, several sets of insert blocks are fixedly connected to the sides of the bottom plate and the top plate, and several sets of slots corresponding to the insert blocks are opened on the bottom plate and the top plate.

[0011] Preferably, the limiting ring, sliding cylinder, support plate, and arc plate are all provided with rubber pads on the side near the reaction cup. Beneficial effects

[0012] This invention provides a reaction cup assembly. Compared with the prior art, it has the following advantages:

[0013] This reaction cup assembly utilizes a spring and sliding cylinder to cushion the falling reaction cup, reducing its descent speed and preventing damage to the reaction cup or reagents due to impact. Through the coordinated movement of an L-shaped rod, sleeve, connecting plate, fixing block, sliding opening, moving plate, and curved plate, the assembly limits the reaction cup during its fall and stationary position, preventing excessive shaking and scratching. The large contact area between the base plate and the tabletop, along with its flat surface, ensures greater stability and effectively prevents tipping during experiments. This allows for stable and convenient placement of the reaction cup, preventing it from tipping over and disrupting the experimental process. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a reaction cup assembly, including a base plate 1, a plurality of support rods 2 fixedly connected to the top of the base plate 1, a top plate 3 fixedly connected to the top of the support rods 2, a limit ring 4 fixedly connected to the top of the top plate 3, a placement hole on the top plate 3, a reaction cup 19 placed in the placement hole, an installation cylinder 10 fixedly connected to the top of the base plate 1, a sliding cylinder 11 slidably connected to the inner wall of the installation cylinder 10, the top of the sliding cylinder 11 abutting against the bottom of the reaction cup 19, a spring 14 fixedly connected to the top of the inner cavity of the sliding cylinder 11, and the bottom of the spring 14 fixedly connected to the top of the base plate 1.

[0022] In use, the reaction cup 19 is aligned with the placement hole on the top plate 3 and lowered. Under gravity, the reaction cup 19 falls until its bottom contacts the top of the sliding cylinder 11. The sliding cylinder 11, under the action of the spring 14, cushions the fall of the reaction cup 19, reducing its falling speed and preventing the impact from excessive speed from affecting the reaction cup 19 or the reagents inside. Compared to placing the reaction cup 19 directly on the table, the bottom plate 1 has a larger contact area with the table and a flatter bottom surface, resulting in greater stability. The limiting ring 4 prevents the reaction cup 19 from tightly adhering to the top of the top plate 3, facilitating subsequent removal of the reaction cup 19. This achieves stable and convenient placement of the reaction cup 19, preventing it from tipping over during the experiment and avoiding any impact on the experimental process.

[0023] The top plate 3 has two sliding plates 16 slidably connected to its bottom. The bottom of the sliding plate 16 is fixedly connected to a support plate 12. The bottom of the support plate 12 is fixedly connected to an arc plate 13. The side of the arc plate 13 closest to the reaction cup 19 abuts against the reaction cup 19.

[0024] The arc plate 13 and the support plate 12 can limit the position of the reaction cup 19 and prevent the reaction cup 19 from shaking significantly.

[0025] A sleeve 5 is slidably fitted on the outside of the support rod 2. A connecting plate 6 is fixedly connected between the two sets of sleeves 5. A movable plate 15 is fixedly connected to the side of the arc plate 13 near the connecting plate 6. A sliding opening 18 is opened on the movable plate 15. A fixing block 17 matching the sliding opening 18 is fixedly connected to the side of the mounting cylinder 10 near the movable plate 15. The fixing block 17 is slidably connected to the sliding opening 18. The sliding opening 18 is inclined.

[0026] An L-shaped rod 7 is fixedly connected to the bottom of the connecting plate 6. The end of the L-shaped rod 7 near the sliding cylinder 11 is fixedly connected to the outside of the sliding cylinder 11.

[0027] When the sliding cylinder 11 descends under the gravity of the reaction cup 19, it drives the sleeve 5 and connecting plate 6 to descend through the connection of the L-shaped rod 7. Then the fixed block 17 descends, and under the action of the sliding port 18, the two sets of moving plates 15 move closer to each other, driving the two sets of arc plates 13 to move closer to each other, thus limiting the reaction cup 19. This can prevent the reaction cup 19 from shaking significantly during the descent and stationary process, and also prevent the reaction cup 19 from scraping against the arc plate 13 when it falls.

[0028] Several sets of insert blocks 8 are fixedly connected to the sides of the base plate 1 and the top plate 3, and several sets of slots 9 corresponding to the insert blocks 8 are opened on the base plate 1 and the top plate 3.

[0029] By inserting the plug 8 of one set of components into the slot 9 of another set of components, the two sets of components can be assembled together, which facilitates the centralized classification and placement of the reaction cup 19 and also improves stability.

[0030] Rubber pads are provided on the side of the limiting ring 4, sliding cylinder 11, support plate 12, and arc plate 13 near the reaction cup 19 to prevent damage to the reaction cup 19.

[0031] Working principle: When in use, align the reaction cup 19 with the placement hole on the top plate 3 and lower it. The reaction cup 19 falls under the action of gravity until the bottom of the reaction cup 19 contacts the top of the sliding cylinder 11. Under the action of the spring 14, the sliding cylinder 11 buffers the fall of the reaction cup 19, reduces the falling speed of the reaction cup 19, and avoids the impact caused by the excessive falling speed from affecting the reaction cup 19 or the reagent in the reaction cup 19. When the sliding cylinder 11 descends under the weight of the reaction cup 19, the sleeve 5 and connecting plate 6 descend via the L-shaped rod 7, causing the fixing block 17 to descend. Under the action of the sliding opening 18, the two sets of moving plates 15 move closer together, causing the two sets of arc-shaped plates 13 to move closer together, thus limiting the reaction cup 19. This prevents the reaction cup 19 from shaking significantly during its descent and resting, and also avoids the reaction cup 19 scraping against the arc-shaped plates 13 during its descent. Compared to placing the reaction cup 19 directly on the table, the bottom plate 1 has a larger contact area with the table and a flatter bottom surface, resulting in greater stability. Under the action of the limiting ring 4, the reaction cup 19 will not be tightly attached to the top of the top plate 3, making it easier to remove the reaction cup 19 later. This achieves stable and convenient placement of the reaction cup 19, preventing it from tipping over during the experiment and avoiding any impact on the experimental process.
