[0002] A rotary mixer is a device for quickly mixing liquids and is widely used in various fields. Mixing is generally carried out in two ways: manual mixing and mechanical mixing. Manual mixing is carried out by manually holding the sample tube for mixing. This method is relatively simple, but it requires labor and takes a long time, and the mixing effect varies greatly. Mechanical mixing is to install the sample tube on the fixed device of the mixer to mix the liquid in the container.

[0003] The existing technology has the following problems:

[0004] The test tube clamps of common rotary mixers on the market all adopt a fixed installation method, and a number of test tube placement holes of different sizes are opened on the surface of the test tube clamp for the placement of test tubes of different sizes. However, in the actual use process, the number of test tubes of the same size to be mixed changes, and the test tubes exceeding the number of placement holes need to wait for the next placement and mixing, which is difficult to meet the use requirements.

[0005] Therefore, we propose a rotary mixer to solve the above drawbacks. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art and propose a rotary mixer.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: a rotary mixer, including a frame, the output end of the driving part inside the frame is fixedly connected with a right end shaft, and the inner wall surface of the frame is rotatably installed with a left end shaft corresponding to the right end shaft. The opposite ends of the right end shaft and the left end shaft are both welded with clamp-type parts, and a U-shaped opening is opened on the top surface of the clamp-type parts. And convex columns welded to the clamp-type parts are respectively arranged on the left and right sides of the port of the U-shaped opening. A rotary frame is arranged between the right end shaft and the left end shaft, and connecting blocks are welded to the left and right sides of the rotary frame corresponding to the clamp-type parts.

A positioning arc is sleeved and installed between the two convex columns of the clamp-type part, and the positioning arc abuts against the outer wall of the butterfly nut. A number of placement holes are arranged in a rectangular array on the surface of the rotary frame. A key panel is arranged on the surface of the frame, and the output end of the key panel is electrically connected with the driving part inside the frame.

[0008] Preferably, a U-shaped frame is welded to the top surface of the rotary rack, and a plurality of plum blossom knobs are screwed to the top surface of the U-shaped frame. A pressing plate is adhered to the bottom of each of the plurality of plum blossom knobs, and the plurality of plum blossom knobs correspond to a plurality of placement holes of the rotary rack one by one. Two limiting strips are adhered to the inner wall of the placement hole of the rotary rack, and a flared opening is formed between the two limiting strips.

[0009] Preferably, the positioning arc is integrally injection-molded from a rubber strip and rubber rings at both ends thereof, and the rubber rings of the positioning arc are sleeved on the convex columns.

[0010] Preferably, the cross section of the limiting strip is in an isosceles trapezoid structure, and the inclined surfaces of the two limiting strips in the placement hole are arranged facing each other.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0024] Please refer to Figures 1-3 , a rotary mixer, including a frame 1, the output end of the driving member inside the frame 1 is fixedly connected with a right end shaft 3, and the inner wall surface of the frame 1 is rotatably installed with a left end shaft 5 corresponding to the right end shaft 3. The opposite ends of the right end shaft 3 and the left end shaft 5 are both welded with plier-shaped parts 4, and a U-shaped opening 12 is opened on the top surface of the plier-shaped part 4. And convex columns 14 welded to the plier-shaped part 4 are respectively arranged on the left and right sides of the port of the U-shaped opening 12. A rotary rack 6 is arranged between the right end shaft 3 and the left end shaft 5. And connecting blocks 9 welded corresponding to the plier-shaped parts 4 are arranged on both the left and right sides of the rotary rack 6. A threaded column 11 is welded on the surface of the connecting block 9, and a part of the threaded column 11 extending to the inside of the U-shaped opening 12 is screwed with a butterfly nut 13. A positioning arc 15 is sleeved and installed between the two convex columns 14 of the plier-shaped part 4, and the positioning arc 15 abuts against the outer wall of the butterfly nut 13. A plurality of placement holes 7 are arranged on the surface of the rotary rack 6 in a rectangular array. A button panel 2 is arranged on the surface of the frame 1, and the output end of the button panel 2 is electrically connected to the driving member inside the frame 1.

[0025] In this embodiment: In order to accommodate test tubes of different sizes in batches, multiple rotating racks 6 can be provided in this device, and the diameters of the placement holes 7 of each rotating rack 6 are different. In order to increase the structural strength of the positioning arc 15, steel wires are installed inside the positioning arc 15. With the setting of the wing nuts 13, it is easy to quickly install and disassemble with the threaded posts 11, increasing the disassembly and assembly efficiency of the rotating rack 6. The parts not involved in this device are the same as the prior art or can be implemented using the prior art.

[0026] Specifically, a U-shaped frame 8 is welded to the top surface of the rotating rack 6, and several plum blossom knobs 10 are screwed to the top surface of the U-shaped frame 8. A pressing plate 16 is adhered to the bottom of each of the several plum blossom knobs 10, and the several plum blossom knobs 10 correspond one by one to the several placement holes 7 of the rotating rack 6. Two limiting strips 17 are adhered to the inner wall of the placement hole 7 of the rotating rack 6, and a flared opening is formed between the two limiting strips 17.

[0027] In this embodiment: By inserting the test tube to be mixed into the placement hole 7, as the test tube goes deeper, the outer wall of the test tube gradually keeps reliable contact with the two limiting strips 17 of the placement hole 7. At this time, by rotating the plum blossom knob 10 provided corresponding to the placement hole 7, the pressing plate 16 at the bottom of the plum blossom knob 10 is made to contact the port of the test tube, realizing the locking of the test tube. Among them, in order to facilitate the installation of the test tube, the distance between the highest point of the pressing plate 16 and the rotating rack 6 is greater than the length of the test tube.

[0028] Specifically, the positioning arc 15 is integrally injection-molded from a rubber strip and rubber rings at both ends thereof, and the rubber rings of the positioning arc 15 are sleeved on the convex posts 14.

[0029] In this embodiment: After the positioning arc 15 is sleeved and installed on the convex post 14, the positioning arc 15 is in a tensioned state, so that it will not fall off easily by itself.

[0030] Specifically, the cross-section of the limiting strip 17 is in an isosceles trapezoid structure, and the inclined surfaces of the two limiting strips 17 in the placement hole 7 face each other.

[0031] In this embodiment: Through the setting of the limiting strip 17, it can be used as a limiting structure in contact with the outer wall of the test tube, ensuring the reliability of the test tube in the placement hole 7 and facilitating the locking of the pressing plate 16.

[0032] Specifically, several screw holes are provided on the top surface of the U-shaped frame 8 corresponding to the plum blossom knobs 10, and the several screw holes are all directly above the several placement holes 7.

[0033] In this embodiment: Through the setting of the several screw holes, it is convenient for the threaded connection of the plum blossom knobs 10 and is beneficial to the locking of the test tube.

[0034] Specifically, a shaft seat is provided at one end of the left end shaft 5 away from the pliers-shaped part 4, and the shaft seat is rotatably connected to the inner wall of the frame 1.

[0035] In this embodiment: Through the setting of the shaft seat, the rotation of the left-end shaft 5 is facilitated.

[0036] Specifically, the axes of the right-end shaft 3 and the left-end shaft 5 are on the same straight line, and the diameters of the right-end shaft 3 and the left-end shaft 5 are the same.

[0037] In this embodiment: Through the setting of the right-end shaft 3 and the left-end shaft 5 with their axes on the same straight line, the installation of the rotating frame 6 is facilitated.

[0038] Working principle: During operation, by extending the connecting blocks 9 at both ends of the rotating frame 6 into the inner sides of the clamp-like members 4 at the opposite ends of the right-end shaft 3 and the left-end shaft 5, the threaded posts 11 of the connecting blocks 9 are extended into the U-shaped openings 12 of the clamp-like members 4. Then, the wing nuts 13 are screwed onto the threaded posts 11, and the end faces of the wing nuts 13 abut against the top faces of the clamp-like members. During this process, by sleeving the annular ends of the positioning arcs 15 onto the convex posts 14 arranged on the left and right sides of the U-shaped opening 12, the rubber positioning arcs 15 are made to abut against the outer walls of the wing nuts 13, achieving the installation of the rotating frame 6. By inserting the test tube to be mixed evenly into the placement hole 7, as the test tube goes deeper, the outer wall of the test tube gradually and reliably abuts against the two limiting strips 17 of the placement hole 7. At this time, by rotating the plum blossom knob 10 corresponding to the placement hole 7, the abutting disc 16 at the bottom of the plum blossom knob 10 is made to contact the port of the test tube, achieving the locking of the test tube. Then, the driving member built into the frame 1 is started by using the key panel 2, so that the right-end shaft 3 arranged at the output end of the driving member rotates until the right-end shaft 3 and the left-end shaft 5 installed with the shaft seat drive the rotating frame 6 to perform rotational mixing processing.

[0039] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
