Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically to a mixing device for testing. Background Technology

[0002] With the development of science and technology, more and more testing experiments require the use of test tubes to observe experimental phenomena. Shaking the test tube is particularly important in the testing process. Some tests in hospital laboratories require the collection of human blood to be placed in a blood collection tube and mixed with an anticoagulant. Using a shaker can quickly mix the above liquids.

[0003] A search revealed Chinese Patent Publication No. CN214915462U, which discloses a mixing and shaking device for laboratory use. The device includes a base frame with two elastic components on the lower surface of its inner wall. The top ends of these elastic components are fixedly connected to the lower surface of a movable frame. A driving component is located on the lower surface of the movable frame. This mixing and shaking device for laboratory use, through the configuration of a cam, a second motor, a second rotating shaft, a rotating plate, a first rotating shaft, a connecting cylinder, a gear ring, and a connecting gear, allows the second motor to drive the cam to press the movable frame upwards. Simultaneously, the first rotating shaft drives the rotating plate and the connecting cylinder to rotate around the first rotating shaft. Simultaneously, the gear ring and the connecting gear mesh to cause the connecting cylinder to rotate around the second rotating shaft. This device can control the connecting cylinder and test tube to revolve around the second rotating shaft while simultaneously rotating on their own axis, and can also perform vertical shaking. This ensures that the overall shaking process can be performed in multiple directions, resulting in a more ideal shaking effect and efficiency, and making the device more practical.

[0004] While this method effectively mixes the liquid in the test tube, it has several drawbacks. For instance, the entire apparatus vibrates during shaking, which can cause equipment displacement. Prolonged shaking can also lead to wear and damage to the connecting structures, affecting usability and reducing its lifespan. Furthermore, the up-and-down shaking of the test tube causes it to rotate, affecting the rotational balance of the connecting cylinder and preventing it from rotating at high speed. This shaking method can easily result in uneven mixing and reduced work efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: a mixing device for testing, comprising: a base plate; a sliding frame, the sliding frame being slidably mounted on the top of the base plate, a shock-absorbing component being installed between the base plate and the sliding frame, a U-shaped plate being installed on the top of the sliding frame, a placement plate being slidably mounted on the bottom of the inner wall of the U-shaped plate, a plurality of placement slots being constructed on the placement plate, the placement slots holding test tubes; a lifting frame, the lifting frame being slidably mounted on the placement plate, a lifting component being installed on the placement plate for driving the lifting frame to rise and fall, a plurality of rubber cover plates being fixedly installed on the bottom of the inner wall of the lifting frame, the number of which corresponds one-to-one with the test tubes; a reciprocating component, the reciprocating component being mounted on the U-shaped plate, for driving the placement plate to slide back and forth; and a rotating component, the rotating component being mounted on the sliding frame, for driving the U-shaped plate to rotate back and forth.

[0009] Furthermore, the reciprocating assembly includes a rotating rod rotatably mounted on one end of the U-shaped plate, with circular plates fixedly mounted on both ends of the rotating rod. Rotating plates are rotatably mounted on both sides of the placement plate. Short rods are fixedly mounted on one side of each of the two circular plates away from the center.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, an embodiment of the present invention provides a test mixer, comprising: a base plate 1;

[0023] A sliding frame 2 is slidably mounted on the top of the base plate. A shock-absorbing assembly 3 is installed between the base plate 1 and the sliding frame 2. A U-shaped plate 4 is installed on the top of the sliding frame 2. A placement plate 5 is slidably mounted on the bottom of the inner wall of the U-shaped plate 4. The placement plate 5 has multiple placement grooves 6, and test tubes 7 are placed in the placement grooves 6. The shock-absorbing assembly 3 includes multiple dampers 31 fixedly mounted between the top of the base plate 1 and the top of the inner wall of the sliding frame 2. Multiple shock-absorbing springs 32 are fixedly mounted between the top of the base plate 1 and the top of the inner wall of the sliding frame 2.

[0024] The lifting frame 8 is slidably installed on the placement plate 5. The placement plate 5 is equipped with a lifting component 9 for driving the lifting frame 8 to rise and fall. Multiple rubber cover plates 81 are fixedly installed on the bottom of the inner wall of the lifting frame 8, and their number corresponds one-to-one with the test tubes 7.

[0025] A reciprocating component 10 is mounted on the U-shaped plate 4 and is used to drive the placement plate 5 to slide back and forth.

[0026] A rotating assembly 11 is mounted on the sliding frame 2 and is used to drive the U-shaped plate 4 to reciprocate. The rotating assembly 11 includes a disc 111 rotatably mounted on the top of the sliding frame 2, the disc 111 being fixedly connected to the U-shaped plate 4, a rotating motor 112 being fixedly mounted on one side of the sliding frame 2, a third gear 113 being fixedly mounted on the output end of the rotating motor 112, and a plurality of teeth 114 being fixedly mounted in an array on the outer periphery of the disc 111, with the third gear 113 meshing with the plurality of teeth 114.

[0027] First, place the test tubes to be mixed into the placement slots 6 on the placement plate 5. The design of the placement slots 6 ensures that the test tubes 7 are placed stably within them, preventing them from shaking or tipping over during the mixing process. Then, activate the lifting component 9 to move the lifting frame 8 down and use the rubber cover plate 81 to seal the top of the test tubes 7, preventing the liquid inside from leaking out. Then, the rotating component 11 starts working, and the output end of the rotating motor 112 drives the third gear 113 to rotate back and forth. Since the third gear 113 meshes with the teeth 114 on the outer periphery of the disc 111, Therefore, the disc 111 will reciprocate in both directions as the third gear 113 rotates, which in turn drives the U-shaped plate 4, which is fixedly connected to the disc 111, to reciprocate as well. The rotation of the U-shaped plate 4 causes the placement plate 5 placed inside it and the test tube 7 on the placement plate 5 to rotate as well, thereby realizing the reciprocating rotation and mixing action of the test tube 7. At the same time, the reciprocating component 10 starts to work, causing the placement plate 5 to slide back and forth on the bottom of the inner wall of the U-shaped plate 4, so that the test tube 7 can also sway left and right in the horizontal direction while rotating, further enhancing the mixing effect. Through the movement of the test tube 7 in multiple directions, it is ensured that the liquid in the test tube 7 can be fully mixed evenly, improving the mixing efficiency and quality. Throughout the mixing process, the damping component 3 plays a crucial role. When the device vibrates during operation, the rebound force generated by the downward damping spring 32 and the damper 31 work together to effectively buffer and reduce the vibration of the device. This reduces the impact of the vibration generated during operation on the device itself and the surrounding environment, prevents the device from shifting due to vibration, and reduces the risk of wear and damage to the device's connecting structure caused by prolonged vibration. This extends the service life of the device and ensures that the mixer can operate stably and efficiently, achieving uniform mixing of the liquid in the test tube 7.

[0028] like Figure 4 As shown, in some embodiments, the lifting component 9 includes an electric push rod 91 fixedly inserted into the placement plate 5, and the telescopic end of the electric push rod 91 is fixedly connected to the top of the inner wall of the lifting frame 8.

[0029] Start the electric push rod 91 to retract its telescopic end, which will drive the lifting frame 8 to move down, thereby allowing the upper rubber cover plate 81 to move down and cover the top of the test tube 7.

[0030] like Figure 1As shown, in some embodiments, the reciprocating assembly 10 includes a rotating rod 101 rotatably mounted on one end of the U-shaped plate 4. Circular plates 102 are fixedly mounted on both ends of the rotating rod 101. Rotating plates 103 are rotatably mounted on both sides of the placement plate 5. Short rods 104 are fixedly mounted on one side of each of the two circular plates 102 away from the center. One end of each of the two rotating plates 103 is rotatably connected to the two short rods 104. A driving assembly 105 for driving the rotating rod 101 to rotate is mounted on the U-shaped plate 4. The driving assembly 105 includes a first gear 1051 fixedly sleeved on the outer surface of the rotating rod 101. A drive motor 1052 is fixedly mounted on one side of the U-shaped plate 4. A second gear 1053 is fixedly mounted on the output end of the drive motor 1052. The first gear 1051 meshes with the second gear 1053.

[0031] When the drive assembly 105 is started, the output end of the drive motor 1052 drives the second gear 1053 to rotate. Since the first gear 1051 and the second gear 1053 mesh with each other, the rotation of the second gear 1053 will drive the first gear 1051 to rotate. The first gear 1051 is fixedly sleeved on the outer surface of the rotating rod 101. Therefore, the rotation of the first gear 1051 will drive the rotating rod 101 to rotate around its axis. As the rotating rod 101 rotates, the circular plates 102 fixed at both ends of it will also rotate accordingly. A short rod 104 is installed on one side of the circular plate 102, away from the center. The short rod 104 moves in a circular trajectory. Rotating plates 103 are rotatably installed on both sides of the placement plate 5. One end of the rotating plate 103 is rotatably connected to the short rod 104. When the circular plate 102 rotates, the short rod 104 drives the rotating plate 103 to swing around its connection point with the placement plate 5. Since the other end of the rotating plate 103 is connected to the placement plate 5, the swinging of the rotating plate 103 pushes the placement plate 5 to slide back and forth on the bottom of the inner wall of the U-shaped plate 4. This reciprocating motion causes the test tube 7 placed on the placement plate 5 to sway left and right in the horizontal direction, thereby further promoting the mixing of the liquid in the test tube 7.

[0032] The rotation speed of the rotating rod 101 can be adjusted by controlling the drive component 105, thereby controlling the speed and stroke of the reciprocating motion of the placement plate 5 to meet the mixing requirements of liquids in different test tubes 7.

[0033] like Figure 4 As shown, in some embodiments, rubber pads 12 are fixedly installed on the inner circumference of multiple placement slots 6, and the test tubes 7 are inserted into the rubber pads 12.

[0034] The softness of the rubber pad 12 helps to protect the test tube 7, preventing it from rubbing against the inner wall of the placement groove 6 and causing wear. It also facilitates the insertion of test tubes 7 within the specified size range, thus having a certain degree of adaptability.

[0035] like Figure 2 As shown, in some embodiments, an anti-slip and shock-absorbing pad 13 is fixedly installed on the bottom of the base plate 1, and a reinforcing block 14 is fixedly installed on both sides of the base plate 1.

[0036] The anti-slip and shock-absorbing pad 13 is used to increase the friction between the base plate 1 and the placement platform, and it has a certain shock absorption performance, which makes it easy to stabilize the device and prevents it from moving easily. The reinforcing block 14 is used to further improve the stability and is made of silicone.

[0037] 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.
