Description

Technical Field

[0001] This utility model relates to the field of reaction cup technology, and in particular to a square reaction cup that can be shaken evenly. Background Art

[0002] Reaction cups are commonly used containers in fully automated luminescence analyzers, and there is a need for automation in their transport or transfer within these analyzers.

[0003] In existing technologies, when shaking reaction cups of different shapes, such as square reaction cups, the four corners of a square reaction cup are subjected to inertial forces in different directions during shaking. This uneven distribution of forces from the corners can affect the overall trajectory of the reaction, causing inconsistent shaking amplitudes in different directions and resulting in asymmetrical movement. This can easily lead to uneven mixing of the liquid or reagents within the reaction cup, affecting the reaction effect and experimental results. Therefore, this paper proposes a square reaction cup that can be shaken evenly to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a square reaction cup that can be shaken evenly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A square reaction cup capable of being shaken evenly includes a reaction cup and an outer frame. The outer frame is fitted onto the outer wall of the reaction cup. Both the inner and outer walls of the reaction cup are square. Multiple sets of sliding grooves are formed inside the reaction cup, and the multiple sets of sliding grooves are evenly spaced. Two sets of side plates are fixedly connected to the two end faces of the outer frame. A sliding rod is fixedly connected between the two sets of side plates. A sliding frame is installed on the outer wall of the reaction cup. The outer wall of the sliding frame is Z-shaped. The end of the sliding frame is slidably connected to the outer wall of the sliding rod. A buffer block is slidably connected to the outer wall of the sliding rod. The sliding frame contacts the outer wall of the sliding rod. A buffer mechanism for buffering the force of the sliding frame is installed on the outer wall of the sliding rod.

[0007] Preferably, the buffer mechanism includes a spring sleeved on both ends of the slide rod, one end of the spring being fixedly connected to the adjacent buffer block, and the other end of the spring being fixedly connected to the adjacent side plate.

[0008] Preferably, the outer wall of the reaction cup is equipped with multiple sets of positioning blocks, and the number of the multiple sets of positioning blocks is the same as the number of multiple sets of carriages.

[0009] Preferably, multiple sets of the slides are respectively engaged on the outer wall of their adjacent positioning blocks, and the outer wall of the positioning block is slidably connected with a rod, which extends through the slide to the other end of the positioning block.

[0010] Preferably, a limiting block is fixedly connected to the end of the insertion rod, and the radius of the limiting block is larger than the radius of the insertion rod.

[0011] Preferably, a second spring is sleeved on the outer wall of the insertion rod, one end of the second spring is fixedly connected to the limiting block, and the other end of the second spring is fixedly connected to the outer wall of the positioning block.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model effectively controls the shaking speed and amplitude of the reaction cup by setting a buffer block and a spring. During the shaking process, the chute guides the liquid flow, avoiding violent movement of the liquid due to inertia and reducing the risk of splashing or uneven distribution. The buffer block and spring absorb kinetic energy and provide reverse elastic force, slowing down the movement speed of the reaction cup, ensuring the smooth flow and uniform mixing of the liquid, reducing the stratification phenomenon caused by excessive centrifugation, and further ensuring the stability and accuracy of the experimental results.

[0014] 2. By setting up positioning blocks and insert rods, users can quickly install or disassemble reaction cups through simple operations without complicated tools or tedious operating steps. Especially in experiments that require frequent replacement of reaction cups, it can greatly save operating time and improve experimental efficiency. At the same time, it ensures that the reaction cups are stably fixed in the outer frame, avoiding loosening or displacement caused by improper installation. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3A square reaction cup that can be shaken evenly includes a reaction cup 1 and an outer frame 2. The outer frame 2 is fitted onto the outer wall of the reaction cup 1. Both the inner and outer walls of the reaction cup 1 are square. Multiple sets of sliding grooves 3 are opened inside the reaction cup 1. The multiple sets of sliding grooves 3 are evenly spaced. Two sets of side plates 7 are fixedly connected to the two end faces of the outer frame 2. A sliding rod 5 is fixedly connected between the two sets of side plates 7. A slide frame 6 is installed on the outer wall of the reaction cup 1. The outer wall of the slide frame 6 is Z-shaped. The end of the slide frame 6 is slidably connected to the outer wall of the sliding rod 5. A buffer block 9 is slidably connected to the outer wall of the sliding rod 5. The slide frame 6 is in contact with the outer wall of the sliding rod 5. A buffer mechanism for buffering the force of the slide frame 6 is installed on the outer wall of the sliding rod 5. The buffer mechanism includes a spring 8 fitted onto both ends of the sliding rod 5. One end of the spring 8 is fixedly connected to the buffer block 9 adjacent to it. The other end of the spring 8 is fixedly connected to the side plate 7 adjacent to it.

[0021] Specifically, during use, the outer frame 2 is held by hand, and by swinging the outer frame 2, the reaction cup 1 inside it is moved back and forth. During the shaking, the slide 6 comes into contact with its adjacent buffer block 9. The buffer block 9 and the spring 8 increase the damping effect, slowing down the movement speed and shaking amplitude of the reaction cup 1. The spring 8 provides a counter-elastic force to alleviate the violent centrifugal force generated by inertia. The buffer block 9 absorbs some kinetic energy through physical contact, preventing the reaction cup 1 from generating violent inertial forces. This avoids the liquid from splashing violently or distributing unevenly due to excessive inertial forces. This slowing effect avoids excessively rapid centrifugal force, making the liquid flow more smoothly and reducing violent rotation or stratification of the liquid in the reaction cup 1, thereby promoting uniform mixing of the liquid.

[0022] Multiple sets of positioning blocks 11 are installed on the outer wall of the reaction vessel 1, the number of which matches the number of multiple sets of slides 6. Each slide 6 is respectively engaged with the outer wall of its adjacent positioning block 11. A rod 10 is slidably connected to the outer wall of each positioning block 11, extending through the slide 6 to the other end of the positioning block 11. A limiting block 4 is fixedly connected to the end of the rod 10, the radius of which is larger than that of the rod 10. A second spring 12 is fitted onto the outer wall of the rod 10, one end of which is fixedly connected to the limiting block 4, and the other end to the outer wall of the positioning block 11. The cooperation between the rod 10 and the positioning blocks 11 allows for quick removal and installation of the reaction vessel 1 from the outer frame 2. Users can easily remove or place the reaction vessel 1 from the outer frame 2 without complicated tools or excessive steps. This design saves time and improves the efficiency of experimental operations, while the spring 12 ensures the stability of the reaction vessel 1 after it is placed in the outer frame 2.

[0023] In this utility model, when the device is used, the reaction cup 1 is gently pushed into the outer frame 2 through the cooperation of the insertion rod 10 and the positioning block 11. The spring 12 ensures that the reaction cup 1 is firmly in the outer frame 2 and prevents the reaction cup 1 from loosening during use. The cooperation between the positioning block 11 and the insertion rod 10 ensures the accurate installation of the reaction cup 1, so that the reaction cup 1 is firmly fixed in the outer frame 2, avoiding positional displacement due to shaking.

[0024] The user holds the outer frame 2 and swings it to make the internal reaction cup 1 shake evenly. During the shaking, the slide 6 contacts the buffer block 9. The buffer block 9 and the spring 8 work together to slow down the speed and amplitude of the reaction cup 1 when it slides close to the end of the side plate 7, increasing the stability of the shaking. The buffer block 9 absorbs the kinetic energy of the reaction cup 1 and reduces the violent centrifugal force caused by inertia. The spring 8 provides a counter-elastic force to reduce the violent movement of the reaction cup 1, so that the reaction cup 1 can stop smoothly after each shaking. This avoids violent splashing or uneven distribution of liquid due to excessive inertial force. In this process, the flow of liquid becomes more gentle, avoiding excessive centrifugal force and reducing violent rotation or stratification of liquid in the reaction cup 1, ensuring uniform mixing of liquid.

[0025] The chute 3 provides a channel for the flow of liquid or reagents inside the reaction cup 1. During shaking, the chute 3 guides the flow direction of the liquid, reducing violent movement caused by inertia and making the liquid flow more smoothly inside the reaction cup 1, preventing splashing or uneven distribution due to violent fluctuations. After use, the user can quickly disassemble the reaction cup 1 as needed. Through the cooperation of the insert 10 between the slide 6 and the positioning block 11, the user can easily remove the reaction cup 1 for cleaning or replacement.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
