Description

Technical Field

[0001] The present invention belongs to the technical field of mixing equipment, and particularly relates to a reagent mixing auxiliary device. Background Art

[0002] During the experiment, it is usually necessary to place multiple substances in the same test tube and then mix them evenly by oscillation.

[0003] Traditional manual oscillation for mixing is time-consuming and laborious, and the mixing effect is usually not ideal. If not held firmly, it is easy to fall during the oscillation process. Therefore, a vortex mixer is mostly used for mixing. For single-tube mixing, the operator places the lower end of the test tube on the foam seat installed at the center of the top of the vortex mixer, holds the upper end of the test tube with one hand, and then starts the vortex mixer to drive the foam seat to perform eccentric circular motion, so as to achieve the mixing of the materials. However, if not pressed firmly, it is easy for the test tube to jump out; for multi-tube mixing, the foam seat with holes dug in the center of the top of the vortex mixer is replaced, and then the test tubes are inserted into the holes on the top surface of the foam seat in sequence. Finally, a pressing plate is set on the upper ends of all the test tubes inserted into the foam seat to limit the axial movement of the test tubes; however, the size of the holes dug in the foam seat cannot be adjusted. Therefore, foam seats with corresponding apertures need to be equipped for different models of test tubes to clamp the test tubes, increasing the cost.

[0004] There is also a structure in which the holes for clamping the test tubes are set to have adjustable apertures. For example, the Chinese invention patent with the application number: CN114471290 A discloses a multi-tube vortex mixer, and specifically discloses that a mechanical driving part and a test tube clamping part are arranged on the frame. The test tube clamping part uses a clamping rope, which includes a base rope and a matching rope. Each two groups of matching ropes and a group of base ropes form a clamping hole, and the aperture of the clamping hole is adjusted by adjusting the matching rope through the mechanical driving part. However, a line contact is formed between the clamping rope and the test tube, and its clamping force is only on a certain cross-section of the test tube. Under the high-speed eccentric rotation of the vortex mixer, its stability is not ideal. Summary of the Invention

[0005] To solve the above-mentioned deficiencies of the prior art, the present invention provides a reagent mixing auxiliary device, which replaces manual pressing during mixing, is applicable to test tubes with different diameter sizes, and can ensure the stability of the test tubes during the eccentric operation of the vortex mixer.

Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following provides a detailed description of the embodiments of the present invention with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0036] As Figures 1 - 16 shown, this embodiment provides a reagent mixing assistance device, which is provided on a vortex mixer main unit 1 with guide columns 2 at both ends of the top. The device includes a connecting member 10, a placing member 20, and a limiting member 30.

[0037] As Figure 1 、 Figure 3 shown, the connecting member 10 includes a connecting plate 11 and a shock pad 12. The connecting plate 11 has a rectangular structure. Limiting rods 111 are respectively vertically provided at the four corners of the connecting plate 11. The cross-section of the limiting rod 111 is a right angle, and the inner right angle of the limiting rod 111 is located on the angular bisector of the corner of the connecting plate 11. The shock pad 12 is provided on the connecting plate 11, and the four corners of the shock pad 12 are respectively adapted to the inner right angles of the corresponding limiting rods 111, so that the limiting rods 111 limit the shock pad 12 in the horizontal direction. A set of T-shaped rods 112 are respectively provided at intervals on both sides of the connecting plate 11, and the vertical parts of the T-shaped rods 112 are vertically connected to the corresponding side surfaces of the connecting plate 11.

[0038] As Figures 1 - 2 、 Figures 4 - 5 shown, the placing member 20 is stacked on the shock pad 12, and the four corners of the placing member 20 are respectively adapted to the inner right angles of the limiting rods 111, so that the limiting rods 111 limit the placing member 20 in the horizontal direction. The placing member 20 includes a placing plate 21 and an adjusting member. As Figure 2 、 Figure 5 shown, the outer shape dimensions of the placing plate 21 are the same as those of the shock pad 12. During application, it is stacked on the shock pad 12. A plurality of rows of placing holes 22 are provided on the placing plate 21. The placing holes 22 penetrate through the upper and lower surfaces of the placing plate 21 for placing test tubes 3; each placing hole 22 is horizontally arranged and has an isosceles trapezoid structure in the horizontal projection. Each row of placing holes 22 is arranged at intervals in the same direction. A receiving groove 221 is provided in the middle of the bottom edge of the isosceles trapezoid corresponding to each placing hole 22; a strip-shaped groove 222 is provided on one side of each row of placing holes 22; recessed grooves 223 are respectively provided in the middle of the two sides of the inner wall of each placing hole 22 in the vertical direction. One end of the recessed groove 223 is communicated with the top edge of the placing hole 22, and the other end is communicated with the receiving groove 221. One of the recessed grooves 223 is communicated with the strip-shaped groove 222.

[0039] Combined with Figure 4 、 Figures 6 - 9As shown, the adjusting member is arranged in the receiving groove 221. The adjusting member includes an adjusting plate 23. The cross-section of the adjusting plate 23 is horizontally arranged in a T-shaped structure. The two sides of the vertical section of the T-shaped structure are adapted to the two sides of the receiving groove 221, and the length of the vertical section of the T-shaped structure is adapted to the depth of the receiving groove 221. The horizontal part of the adjusting plate 23 is located in the placing hole 22. On both sides of the vertical section of the T-shaped structure of the adjusting plate 23, there are vertically arranged support rods 231 respectively. At one end of the support rod 231 away from the adjusting plate 23 on one side, there is a U-shaped seat 232. The horizontal part of the U-shaped seat 232 is parallel to the vertical section of the T-shaped structure of the adjusting plate 23, and the opening of the U-shaped seat 232 faces the groove 223. Vertically arranged rollers 233 are provided at the opening of the U-shaped seat 232, and the rollers 233 are in rolling contact with the side wall of the groove 223 on the side where the strip-shaped groove 222 is not connected. The support rod 231 on the other side extends into the strip-shaped groove 222. A strip-shaped rod 234 is arranged in the strip-shaped groove 222. The length direction of the strip-shaped rod 234 is consistent with the length direction of the strip-shaped groove 222. One end of the support rod 231 on the other side extending into the strip-shaped groove 222 is perpendicularly connected to the strip-shaped rod 234. One end of the strip-shaped rod 234 extends out of the outer wall of one end of the placing plate 21 along one end of the strip-shaped groove 222. One end of each strip-shaped rod 234 extending out of the placing plate 21 is connected to the same cross plate 235. A circular hole is provided in the middle of the cross plate 235. An I-shaped sleeve is arranged in the circular hole. The vertical part of the sleeve is arranged in the circular hole and is rotationally matched with the circular hole. The horizontal parts at both ends of the sleeve are respectively located on both sides of the cross plate 235. The horizontal part at the outer end of the sleeve is coaxially connected with an adjusting screw 236.

[0040] Combined Figures 4 - 5 As shown, a horizontally arranged U-shaped frame 211 is provided at one end of the placing plate 21. The opening of the U-shaped frame 211 faces one end of the placing plate 21. The front ends of the two side arms of the U-shaped frame 211 are respectively perpendicularly connected to the placing plate 21. The top surface of the upper side of the U-shaped frame 211 is flush with the top surface of the placing plate 21. When the placing plate 21 is stacked on the anti-collision pad 12, the lower sides of the two side arms of the U-shaped frame 211 are spaced above the top of the limiting rod 111 to prevent interference between the placing plate 21 and the top of the limiting rod 111 when the placing plate 21 is stacked on the anti-collision pad 12, so as to avoid the situation where one end of the placing plate 21 is high and the other end is low when the placing plate 21 is stacked on the anti-collision pad 12. A threaded hole is provided in the horizontal part of the U-shaped frame 211, and the adjusting screw 236 is in threaded cooperation with the threaded hole.

[0041] During use, according to the diameter size of the placed test tube 3, rotate the adjusting screw 236, so that the adjusting screw 236 pushes the cross plate 235 to move towards the placing plate 21, thereby enabling the strip-shaped rod 234 to move along the strip-shaped groove 222, so that the strip-shaped rod 234 drives the support rod 231 on the other side of the adjusting plate 23 to move synchronously, so that the adjusting plate 23 moves along the height direction of the placing hole 22 towards the top edge of the placing hole 22. During the movement, the roller 233 rolls along the side wall of the groove 223 on the side where the strip-shaped groove 222 is not connected. When the outer walls of the test tube 3 are respectively in contact with both sides of the placing hole 22 and the horizontal part of the adjusting plate 23 and the side wall of the test tube 3, stop rotating the adjusting screw 236, thereby realizing the limit of the test tube 3. Therefore, by rotating the adjusting screw 236 to control the position of the horizontal part of the adjusting plate 23 in the placing hole 22, the size of the space between the top of the placing hole 22 and the horizontal part of the adjusting plate 23 is adjusted to meet the usage requirements of test tubes 3 with different diameters.

[0042] Specifically, as Figure 1 、 Figure 10 shown, the limiting member 30 includes a pressing plate 31, a flexible pad 32, and an adjusting belt 33. Support ears 314 are respectively provided at both ends of the pressing plate 31. During use, the support ears 314 are respectively inserted into the corresponding guide posts 2, and the support ears 314 are slidably connected to the guide posts 2.

[0043] The flexible pad 32 is provided on the bottom surface of the pressing plate 31. During use, it is stacked on the upper end of the test tube 3 and used to press against the upper end of the test tube 3 to realize the axial limit of the test tube 3.

[0044] One set of adjusting belts 33 is symmetrically and spaced on each side of the pressing plate 31 respectively. The adjusting belt 33 is made of rubber. The upper end of the adjusting plate 23 is connected to the outside of the pressing plate 31, and waist-shaped holes 331 are arranged in an array along the length direction of the adjusting belt 33.

[0045] During use, vertically insert the support ears 314 at both ends of the pressing plate 31 corresponding to the guide posts 2 with the flexible pad 32 facing downwards. When the bottom surface of the flexible pad 32 abuts against the upper end of the test tube 3, pull the adjusting belt 33 to make the waist-shaped hole 331 pass through the T-shaped rod 112, thereby realizing the flexible connection between the pressing plate 31 and the connecting plate 11.

[0046] Both the anti-collision pad 12 and the flexible pad 32 can be made of foam pads or sponge pads.

[0047] Specific usage process: Place the placing member 20 on the operating table with the side of the top surface of the U-shaped frame 211 flush with the top surface of the placing plate 21 facing upward, and insert the test tube 3 filled with the reagent to be mixed into the placing hole 22. By rotating the adjusting screw 236, the outer circumference of the test tube 3 is limited by the inner walls on both sides of the placing hole 22 and the horizontal part of the adjusting plate 23. At this time, the placing member 20 can act as a substitute for the test tube rack, eliminating the need to place the test tube 3 in the test tube rack first and then insert it one by one into the foam seat placed on the vortex mixer main unit 1, thus shortening the operation time and improving work efficiency.

[0048] Insert the connecting seat 113 at the bottom of the connecting plate 11 into the rotating shaft in the middle of the vortex mixer main unit 1. Then stack the placing member 20 with the test tube 3 on the anti-collision pad 12, and vertically place the four corners on the lower side of the placing plate 21 corresponding to the inner right angles of the limiting rods 111.

[0049] Finally, vertically place the limiting member 30, so that the supporting ears 314 at both ends of the pressing plate 31 vertically penetrate downward along the corresponding guide posts 2. Pull the adjusting belt 33 to limit the upper end of the test tube 3 with the flexible pad 32, and ensure that the waist-shaped holes 331 at the same height of each adjusting belt 33 are hooked to the corresponding T-shaped rods 112. Then turn on the switch on the vortex mixer main unit 1 to simultaneously mix the reagents in multiple test tubes 3.

[0050] As Figures 10 - 13 shown, as a preferred embodiment, through holes 311 are provided in the middle of the pressing plate 31 and the flexible pad 32, and a plugging member 34 is vertically movably arranged in the through holes 311.

[0051] As Figure 13 shown, a vertical frame 312 is vertically and perpendicularly provided on the top surface of the pressing plate 31, and the cross-section of the vertical frame 312 is in a U-shaped structure. A sealing plate is provided at the upper end of the vertical frame 312 to connect the three sides at the upper end of the vertical frame 312 to increase the stability of the vertical frame 312. The open side of the vertical frame 312 is away from the through hole 311, and the other side faces the through hole 311. A vertical groove 313 communicating with the horizontal part of the vertical frame 312 is vertically provided on the side of the vertical frame 312 facing the through hole 311.

[0052] As Figures 11 - 12 shown, the plugging member 34 includes an L-shaped rod 341, a guide plate 342, a tension spring 343, a pull rod 344, a circular plate 345, and a backing plate 346. The inner right angle of the L-shaped rod 341 faces downward, the vertical part of the L-shaped rod 341 is horizontally arranged, and one end of the vertical part of the L-shaped rod 341 extends into the vertical groove 313 and is perpendicularly connected to one side of the guide plate 342. The lower end of the horizontal part of the L-shaped rod 341 is connected to the top surface of the circular plate 345. A pressure rod 3421 is vertically provided at the upper end of the guide plate 342, and the upper end of the pressure rod 3421 penetrates through the sealing plate. A guiding groove 3422 is provided on the other side of the guide plate 342, and the guiding groove 3422 is in an inverted isosceles triangle structure, and a positioning groove 3423 is recessed downward at the upper horizontal part thereof.

[0053] The tension spring 343 is arranged inside the vertical frame 312. The upper end of the tension spring 343 is connected to the lower end of the guide plate 342, and the lower end of the tension spring 343 is connected to the pressure plate 31. The pull rod 344 is vertically arranged on one side of the guide plate 342. A convex block is arranged on the top surface of the pressure plate 31. The lower end of the pull rod 344 is rotatably connected to the convex block. A round rod is vertically arranged on the side of the upper end of the pull rod 344 facing the guide plate 342. A rotating sleeve 3441 is arranged at one end of the round rod, and the rotating sleeve 3441 rolls in the guide groove 3422.

[0054] The outer diameter of the round plate 345 is adapted to the inner diameter of the through hole 311, and the thickness of the round plate 345 is the same as the thickness of the pressure plate 31. The backing plate 346 is arranged on the bottom surface of the round plate 345, and the material of the backing plate 346 is the same as the material of the flexible pad 32 and has the same thickness.

[0055] As Figure 1 、 Figures 14 - 15 shown, when it is necessary to mix reagents in multiple test tubes 3 respectively, press the pressure lever 3421 vertically downward so that the round plate 345 is vertically inserted into the through hole 311. At this time, the rotating sleeve 3441 on the pull rod 344 is located in the positioning groove 3423 above the guide groove 3422. At this time, the tension spring 343 is compressed, generating an upward elastic force. The rotating sleeve 3441 at the upper end of the pull rod 344 mechanically limits the guide groove 3422, so as to ensure that the round plate 345 is always located in the through hole 311, thereby blocking the through hole 311 and preventing the test tube 3 corresponding to the lower part of the through hole 311 from being unable to be limited.

[0056] In this state, the distance between the lower end of the guide plate 342 and the top surface of the pressure plate 31 is greater than the vertical linear distance between the positioning groove 3423 and the upper end of the guide groove 3422 to ensure that there is a moving space when the pressure lever 3421 is pressed downward again.

[0057] As Figure 13 shown, when the amount of reagent to be mixed is large, the reagent to be mixed can be placed in the conical flask 4 with a larger capacity. Insert the connecting seat 113 onto the rotating shaft in the middle of the vortex mixer main body 1, and then place the conical flask 4 containing the reagent at the center of the top surface of the anti-collision pad 12.

[0058] Then press the pressure lever 3421 downward so that the rotating sleeve 3441 moves upward out of the positioning groove 3423, and under the action of the restoring force of the tension spring 343, the guide plate 342 moves vertically upward, so that the rotating sleeve 3441 is located at the lower end of the guide groove 3422 as Figure 12 shown in the state, so that the L-shaped rod 341 moves upward along the vertical groove 313, thereby driving the round plate 345 and the backing plate 346 to move upward out of the upper part of the through hole 311.

[0059] Finally, place the limiting member 30 vertically, so that the lugs 314 at both ends of the pressing plate 31 penetrate vertically downward along the corresponding guide posts 2, and make the through holes 311 correspond to the upper end of the conical flask 4 and penetrate vertically downward. Use the flexible pad 32 to limit the upper part of the conical flask 4, and pull the adjusting belt 33, as Figure 16 shown, limit the upper end of the test tube 3 with the flexible pad 32, and ensure that the waist-shaped holes 331 at the same height of each adjusting belt 33 are hooked to the corresponding T-shaped rods 112. Then start the switch on the vortex mixer main unit 1 to mix the reagents in the conical flask 4.

[0060] In addition, by pressing the pressing rod 3421 to control the up and down movement of the plugging member 34, not only the operation is convenient, but also the plugging member 34 is not easy to be lost.

[0061] The above are only the preferred embodiments of the present invention, and do not represent that they are the only ones or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent substitutions made to the present invention all fall within the scope of protection of the present invention.
