A modular mixing device for laboratory use

Abstract

This utility model provides a modular mixing device for laboratory use, comprising: a housing, inside which a test tube rack is slidably connected, and test tube clamps are fixedly installed at the upper end and the bottom of the test tube rack. This modular mixing device for laboratory use, through the design of a sliding groove, a cap, locking blocks, locking grooves, and test tube clamps, utilizes an arc-shaped sliding groove combined with a slider at the bottom of the test tube rack. When the motor-driven rotating rod rotates, the test tube rack can both rotate in a circle and move up and down along an arc-shaped trajectory, making the movement path of the test tubes complex and allowing for more thorough mixing of reagents. When the cap is placed on the test tube rack, the cap can precisely seal the test tubes, preventing liquid from splashing out during equipment operation, avoiding reagent waste and cross-contamination. The locking blocks and locking grooves fit tightly together, firmly locking the cap and preventing it from accidentally opening due to vibration. The compression spring, contact block, and anti-slip layer inside the test tube clamps work together to flexibly adjust according to the size of the test tubes and the placement pressure, tightly fixing the test tubes and preventing them from slipping.

Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to a modular mixing equipment for laboratory use. Background Technology

[0002] In the laboratory, different experiments have different requirements for the temperature control method, rotation speed, size, and fixtures of the shaker. Currently, in order to meet these needs, the laboratory needs to be equipped with several shakers of various functions for different experiments.

[0003] However, existing mixing equipment has the following problems when in use:

[0004] Traditional mixing equipment, such as simple hand-cranked mixers, is not only labor-intensive when dealing with large-scale samples, but also struggles to guarantee uniform and consistent mixing. Some early electric mixers lack flexibility, only adapting to specific test tube or container sizes, which proves inadequate when experiments require processing samples of varying sizes. Furthermore, these traditional devices pose safety risks; for example, sample spillage during high-speed operation can lead to experimental failure, injury to personnel, and reagent contamination.

[0005] This invention can effectively mix reagents in test tubes, improve mixing efficiency and quality, prevent liquid splashing, avoid reagent waste and cross-contamination, ensure the safety of the experimental environment, and also securely fix test tubes of different materials to meet diverse experimental needs. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a modular mixing device for laboratory use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular mixing device for laboratory use, comprising: a box body, wherein a test tube rack is slidably connected inside the box body, and test tube clamps are fixedly installed at the upper end and the bottom of the test tube rack; a mixing chamber is opened inside the box body, and sliding grooves are opened at both the left and right ends of the mixing chamber, the sliding grooves are arc-shaped and slidably connected to the test tube rack; a plurality of test tube openings are opened at the upper end and the bottom of the test tube rack, and test tube clamps are fixedly installed at the front and rear ends of the test tube openings, the test tube clamps being composed of a rear clamp block and a front clamp block.

[0008] A further preferred embodiment: the rear hinge of the box body is connected to a box cover, a motor is fixedly installed at the left end of the box body, a rotating rod is rotatably connected inside the box body, one end of the rotating rod is fixedly connected to the output end of the motor, and the rotating rod is fixedly connected to the inside of the test tube rack.

[0009] A further preferred embodiment: sliders are fixedly installed at the bottom of both the left and right ends of the test tube rack, the sliders are slidably connected to the slide grooves, and a cover plate is connected to the rear hinge of the test tube rack. Several caps are fixedly installed on the side of the cover plate that presses against the test tube rack, and the caps press against the top of the test tubes.

[0010] A further preferred embodiment: locking blocks are fixedly installed on the left and right sides of the front of the cover plate, and locking grooves are fixedly installed on the left and right sides of the front of the test tube rack, with the locking blocks and locking grooves being matched.

[0011] A further preferred embodiment: both the rear clamping block and the front clamping block are composed of a fixing block, a contact block, a compression spring, and an anti-slip layer.

[0012] A further preferred embodiment: one end of the fixing block is fixedly connected to the inner wall of the test tube opening, the other end of the fixing block is fixedly installed with a contact block, a compression spring is fixedly installed between the contact block and the fixing block, and an anti-slip layer is fixedly installed on the contact surface between the contact block and the test tube. Beneficial effects

[0013] 1. The device is equipped with a cover plate, a cap, a locking block, and a locking groove. The cover plate is connected to the test tube rack via a hinge, making it easy to open and close. When the cover plate is pressed onto the test tube rack, the cap fixed on it can accurately press onto the top of the test tube, providing additional sealing protection for the test tube. This effectively prevents the liquid in the test tube from splashing out due to violent shaking during equipment operation, avoiding waste and cross-contamination of experimental reagents, while ensuring the safety of experimental personnel and reducing the potential risk of chemical reagent hazards. The locking block and locking groove are matched and installed in corresponding positions on the cover plate and the test tube rack. After the locking block is inserted into the locking groove, the cover plate and the test tube rack are tightly fixed, ensuring that the cover plate will not be accidentally opened due to vibration or other reasons during equipment operation, thus enhancing the overall stability and reliability of the equipment.

[0014] 2. Equipped with a sliding groove, motor, and rotating rod, the motor's output drives the rotating rod to rotate at high speed. Since the rotating rod is securely connected to the inside of the test tube rack, the rack rotates synchronously, allowing the test tubes to quickly enter a mixing state, significantly improving experimental efficiency. Sliding blocks installed at the bottom of both ends of the test tube rack are slidably connected to the sliding groove. As the test tube rack rotates with the rotating rod, the sliding blocks slide along the arc-shaped sliding groove. This allows the test tube rack to move up and down along a specific arc-shaped trajectory while rotating. This composite motion mode produces more complex and varied motion trajectories for the test tubes. Compared to simple rotation, this allows the reagents in the test tubes to mix more thoroughly and evenly, effectively improving the mixing effect and providing higher quality sample mixing assurance for various experiments, further enhancing the accuracy and reliability of experimental results.

[0015] 3. By incorporating a compression spring, a contact block, and an anti-slip layer, the compression spring is connected at one end to a fixing block and at the other end to the contact block. When the test tube is placed at the mouth of the test tube, the elastic deformation of the compression spring plays a crucial role. It can adaptively adjust its extension and contraction according to the size of the test tube and the pressure during placement, ensuring that the contact block always fits tightly against the outer wall of the test tube, providing all-round support and fixation for the test tube. The contact block, as the component that directly contacts the test tube, is also ingeniously designed. Its shape and material selection are guided by fitting the test tube, which can evenly distribute pressure and prevent the test tube from being damaged due to excessive local force. The anti-slip layer is attached to the contact surface between the contact block and the test tube, further enhancing the friction between the two. This not only effectively prevents the test tube from shaking or slipping due to vibration and high-speed rotation during equipment operation, ensuring the stability and safety of the mixing process, but also makes the equipment compatible with test tubes of different materials and surface roughness, greatly improving the versatility and practicality of the equipment and providing reliable protection for experimental operations.

[0016] 4. In summary, this modular laboratory mixing device, with its structure including a slide, cap, locking block, locking groove, and test tube clamp, features an arc-shaped slide that, combined with a slider at the bottom of the test tube rack, allows the rack to rotate both circularly and move up and down along an arc-shaped trajectory when the motor-driven rotating rod rotates. This complex movement path of the test tubes ensures more thorough mixing of reagents, significantly improving mixing efficiency and quality. The cap, connected to a cover plate, precisely seals the test tubes when placed on the rack, preventing liquid from splashing out during operation, avoiding reagent waste and cross-contamination, and ensuring a safe experimental environment. The locking block and locking groove work together to securely lock the cover plate, preventing accidental opening due to vibration and enhancing the stability of the equipment. The compression spring, contact block, and anti-slip layer inside the test tube clamp work together to flexibly adjust according to the size of the test tubes and the placement pressure, tightly fixing the test tubes and preventing slippage. It is also compatible with test tubes of various materials, meeting diverse experimental needs. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-4In this embodiment of the present invention, a modular mixing device for laboratory use includes: a housing 1, a test tube rack 2 slidably connected inside the housing 1, test tube clamps 3 fixedly installed at the upper end and the bottom of the test tube rack 2, a mixing chamber 102 inside the housing 1, and sliding grooves 103 at both the left and right ends of the mixing chamber 102, the sliding grooves 103 being arc-shaped and slidably connected to the test tube rack 2, a plurality of test tube openings 206 at the upper end and the bottom of the test tube rack 2, and test tube clamps 3 fixedly installed at the front and rear ends of the test tube openings 206, the test tube clamps 3 being composed of a rear clamping block 301 and a front clamping block 302, a housing cover 101 hinged to the rear end of the housing 1, and a test tube clamp 3 fixedly installed at the left end of the housing 1. Motor 104, inside housing 1, a rotating rod 105 is rotatably connected. One end of the rotating rod 105 is fixedly connected to the output end of motor 104, and the rotating rod 105 is fixedly connected to the inside of test tube rack 2. Slider blocks 201 are fixedly installed at the bottom of both ends of test tube rack 2, and the sliders 201 are slidably connected to the slide grooves 103. The rear clamping block 301 and the front clamping block 302 are both composed of a fixing block 303, a contact block 304, a compression spring 305, and an anti-slip layer 306. First, open the housing cover 101 and place the test tubes to be mixed into the test tube openings 206 at the top and bottom of the test tube rack 2. The test tubes will be fixed by the test tube clamps 3. The rear clamping block 301 and the front clamping block 302 of the test tube clamps 3 work together. 1. The fixing block 303 in the front clamping block 302 provides support. The compression spring 305 keeps the contact block 304 tightly against the outer wall of the test tube. The anti-slip layer 306 prevents the test tube from slipping during the fixing process, ensuring that the test tube is securely installed on the test tube rack 2. Close the box cover 101 and prepare to start the mixing work. Turn on the motor 104. The output end of the motor 104 drives the rotating rod 105 to rotate. Since the rotating rod 105 is fixedly connected to the inside of the test tube rack 2, the rotation of the rotating rod 105 will drive the test tube rack 2 to rotate synchronously. During the rotation of the test tube rack 2, the sliders 201 at the bottom of its left and right ends will slide along the slide groove 103. Because the slide groove 103 is arc-shaped, this allows the test tube rack 2 to slide along the slide groove 103 while rotating. The test tubes move up and down along an arc-shaped trajectory, creating a complex motion trajectory for the test tube rack 2, achieving a better mixing effect. During the movement of the test tubes, the test tube clamp 3 continuously and stably fixes the test tubes. The compression springs 305 in the rear clamp block 301 and the front clamp block 302 will extend and retract according to the force during the movement of the test tubes, ensuring that the contact block 304 always makes close contact with the test tubes. The anti-slip layer 306 ensures that the test tubes will not shake or fall off in the test tube clamp 3, ensuring the stability and safety of the mixing process. When the preset mixing time or effect is reached, the motor 104 is turned off, the box cover 101 is opened, and the mixed test tubes are taken out from the test tube rack 2, completing the entire mixing process.

[0024] In this embodiment of the present invention, a cover plate 202 is connected to the rear hinge of the test tube rack 2. Several sealing caps 203 are fixedly installed on the side of the cover plate 202 that presses against the test tube rack 2. The sealing caps 203 cover the upper end of the test tubes. Locking blocks 204 are fixedly installed on the left and right sides of the front of the cover plate 202. Locking grooves 205 are fixedly installed on the left and right sides of the front of the test tube rack 2. The locking blocks 204 and locking grooves 205 are matched. When a test tube is placed into the test tube opening 206, the rear hinge of the test tube rack 2 is rotated. The cover plate 202 connected to the page presses onto the test tube rack 2. At this time, several caps 203 fixedly installed on the cover plate 202 will cover the upper end of the test tube, further sealing the test tube and preventing internal liquid from splashing out or external impurities from entering. Then, the locking blocks 204 on the left and right sides of the front of the cover plate 202 are aligned with the locking grooves 205 on the left and right sides of the front of the test tube rack 2 and inserted to lock the cover plate 202, ensuring that the cover plate 202 is tightly fixed to the test tube rack 2.

[0025] In this embodiment of the invention, one end of the fixing block 303 is fixedly connected to the inner wall of the test tube opening 206, and the other end of the fixing block 303 is fixedly installed with a contact block 304. A compression spring 305 is fixedly installed between the contact block 304 and the fixing block 303. An anti-slip layer 306 is fixedly installed on the contact surface between the contact block 304 and the test tube. The test tube to be mixed is placed in the test tube opening 206 at the top and bottom of the test tube rack 2. At this time, the test tube clamp 3 begins to play a fixing role. In the structure of the rear clamp 301 and the front clamp 302 of the test tube clamp 3, one end of the fixing block 303 is firmly fixedly connected to the inner wall of the test tube opening 206, providing stable support for the entire structure. The contact block 304, which is fixedly installed at the other end of the fixed block 303, can fit tightly against the outer wall of the test tube under the action of the compression spring 305. The compression spring 305 is installed between the contact block 304 and the fixed block 303. It has good elasticity. When the test tube is placed into the test tube opening 206, it will squeeze the contact block 304. The compression spring 305 will be compressed and deformed accordingly, thereby generating a reaction force to push the contact block 304 to press tightly against the test tube. At the same time, the anti-slip layer 306 fixedly installed on the contact surface between the contact block 304 and the test tube further increases the friction between them, effectively preventing the test tube from slipping during the fixing process and ensuring that the test tube is stably installed on the test tube rack 2.

[0026] Working principle: Open the lid 101 and place the test tubes to be mixed into the test tube openings 206 at the top and bottom of the test tube rack 2. At this time, the test tube clamps 3 begin to play a fixing role. In the structure of the rear clamp 301 and the front clamp 302 of the test tube clamps 3, one end of the fixing block 303 is firmly fixed to the inner wall of the test tube opening 206, providing stable support for the entire structure. The contact block 304 is fixedly installed at the other end of the fixing block 303. Under the action of the compression spring 305, it can tightly fit the outer wall of the test tube. The compression spring 305 is installed between the contact block 304 and the fixing block 303. It has good elasticity. When the test tube is placed into the test tube opening 206, it will squeeze the contact block 304, and the compression spring 305 will be compressed and deformed accordingly. The reaction force pushes the contact block 304 tightly against the test tube. Simultaneously, the anti-slip layer 306 fixedly installed on the contact surface between the contact block 304 and the test tube further increases the friction between them, effectively preventing the test tube from slipping during the fixing process and ensuring the test tube is securely installed on the test tube rack 2. Rotating the cover plate 202 connected to the rear hinge of the test tube rack 2 causes the cover plate 202 to press against the test tube rack 2. At this time, several caps 203 fixedly installed on the cover plate 202 will cover the top of the test tube, further sealing it and preventing internal liquid from splashing out or external impurities from entering. Next, align the locking blocks 204 on the left and right sides of the front of the cover plate 202 with the locking grooves 205 on the left and right sides of the front of the test tube rack 2 and engage them to lock the cover plate 202, ensuring its secure installation. The cover plate 202 is tightly fixed to the test tube rack 2. The box cover 101 is closed, and preparation for mixing begins. The motor 104 is turned on, and its output drives the rotating rod 105 to rotate. Since the rotating rod 105 is fixedly connected to the inside of the test tube rack 2, its rotation causes the test tube rack 2 to rotate synchronously. During rotation, the sliders 201 at the bottom of the left and right ends of the test tube rack 2 slide along the slide groove 103. Because the slide groove 103 is arc-shaped, the test tube rack 2 moves up and down along the arc-shaped trajectory while rotating, resulting in a complex motion trajectory for the test tubes on the rack 2, achieving a better mixing effect. During the movement of the test tubes, the test tube clamp 3 continuously and stably fixes them. The rear clamp 301 and the front clamp 302... The compression spring 305 adjusts its extension and retraction according to the force applied to the test tube during movement. For example, when the rotation speed or direction of movement of the test tube rack 2 changes, the test tube will be subjected to forces of different directions and magnitudes. At this time, the compression spring 305 can adaptively adjust its extension and retraction to ensure that the contact block 304 is always in close contact with the test tube. The anti-slip layer 306 ensures that the test tube will not shake or fall off in the test tube clamp 3. At the same time, the cap 203 is always tightly pressed against the top of the test tube. The cap 202 is kept stable by locking the locking block 204 and the locking groove 205, further ensuring the stability and safety of the mixing process and preventing the liquid in the test tube from overflowing during vigorous movement. When the preset mixing time or effect is reached, the motor 104 is turned off and the box cover 101 is opened.First, unlock the locking blocks 204 on the left and right sides of the front of the cover plate 202 from the locking grooves 205 on the left and right sides of the front of the test tube rack 2. Then, rotate the cover plate 202 to open it around the hinge. Finally, remove the mixed test tubes from the test tube rack 2 to complete the entire mixing process.
