Description

Technical Field

[0001] This utility model relates to the technical field of liquid mixing devices, specifically a multi-station synchronous liquid mixing device. Background Technology

[0002] A mixer is a common laboratory instrument used to thoroughly mix multiple liquids in a container. Currently, most common mixers are designed as single-carrier or array carriers, which cannot be compatible with mixing liquids under heavy loads. That is, when the object above the mixer is too heavy, vibration mixing cannot be achieved normally. When the mixing work requires moving the test tube (and the liquid inside) and the test tube rack together, the mixing work will be difficult to carry out. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a multi-station synchronous liquid mixing device.

[0004] The technical solution of this utility model is as follows: A multi-station synchronous liquid mixing device includes a main board and a drive system mounted on it. Several mixing systems are connected to the drive system. Test tubes to be mixed can be placed on the mixing systems, and the operation of the drive system can drive the mixing systems to achieve the mixing of liquid in the test tubes.

[0005] As the core technical concept of this utility model, the driving system includes a drive motor with an eccentric shaft at its transmission end. The mixing system includes connecting rods and a test tube rack located on the upper part of the system, which can fix the test tubes. The mixing system also includes a slide rail and a slider slidably mounted on it. One end of the connecting rod is rotatably connected to the slider, and the other end is rotatably connected to the eccentric shaft. Based on this structure, the action of the drive motor can drive the eccentric shaft to rotate, which in turn drives the eccentric rotation of one end of several connecting rods connected to the eccentric shaft, ultimately driving the test tube rack on it to move, thereby achieving synchronous mixing of the liquid in several test tubes. This method of driving several connecting rods to move through the eccentric shaft reduces the load on a single connecting rod. Combined with the action of the drive motor, several test tubes can be placed on several mixing systems for mixing. Moreover, even if the test tube rack (along with the test tubes and their internal liquids) on the upper part of the connecting rod has a large load, the mixing of the liquid can still be completed smoothly, effectively ensuring the mixing effect of the liquid.

[0006] As described above, in a preferred embodiment of the multi-station synchronous liquid mixing device, to facilitate the assembly and disassembly of test tubes relative to the test tube rack, the test tube rack includes a vertical support with an opening on its upper side, and a clamping block that can clamp and fix the test tubes in the opening is movably provided on one side of the opening.

[0007] As a further preferred embodiment, in order to facilitate the experimenter's real-time observation of the mixing status of the liquid in the test tube during the mixing process, the support includes a U-shaped frame with a fixing block on its upper side, and the opening is located on the fixing block.

[0008] Preferably, to prevent the test tubes from detaching from the test tube rack during shaking, the upper side of the fixing block is also provided with a pressure block that can restrict the upward movement of the test tube opening.

[0009] As described above, in a preferred embodiment of the multi-station synchronous liquid mixing device, to prevent the test tube from shaking during the mixing process and to ensure the clamping and fixing effect of the test tube by the clamping block, the clamping side and / or the side wall of the opening of the clamping block are also provided with arc notches, and when both the clamping side and the side wall of the opening of the clamping block are provided with arc notches, the two arc notches are arranged opposite to each other.

[0010] As a further preferred embodiment, in order to ensure that the mixing device can adapt to high load operation and that a single test tube rack can fix a certain number of test tubes at one time, multiple sets of the arc notches are arranged in parallel.

[0011] Preferably, the support between the adjacent groups of arc notches is also provided with a vertical isolation plate.

[0012] As described above, in order to further reduce the load on the drive motor and ensure the mixing effect of the mixing device on the liquid, a column is vertically provided on the upper side of the slider, and the two ends of the connecting rod are rotatably connected to the column and the eccentric shaft respectively through bearings.

[0013] The beneficial effects of this utility model are as follows: This utility model is a multi-station synchronous liquid mixing device. The action of the drive motor can drive the eccentric shaft to rotate, which in turn drives the eccentric rotation of one end of several connecting rods connected to the eccentric shaft, and finally drives the test tube rack on it to move, realizing the synchronous mixing of liquid in several test tubes. This method of driving several connecting rods to move through the eccentric shaft reduces the load on a single connecting rod, that is, avoids a single connecting rod bearing a large number of test tubes. Instead, several test tubes are placed on multiple mixing systems. Combined with the action of the drive motor, several test tubes can be placed on several mixing systems. Moreover, even if the test tube rack on the upper part of the connecting rod has a large load, the liquid mixing work can still be completed smoothly, effectively ensuring the mixing effect of the liquid.

[0016] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0017] Example This embodiment provides a multi-station synchronous liquid mixing device. See [link / reference] Figure 1 The device includes a horizontally positioned main board 1 and a drive system 2 mounted on it. Several mixing systems 3 are connected to the drive system 2. Test tubes to be mixed can be placed on the mixing systems 3, and the operation of the drive system 2 can drive the mixing systems 3 to move, thereby achieving the mixing of liquid in the test tubes. The structure of the mixing device (the above-mentioned multi-station synchronous liquid mixing device) will be described in detail below with reference to the accompanying drawings.

[0018] In this embodiment, combined with Figure 2 Firstly, regarding the structure of the drive system 2, it includes a base block 21 disposed on the upper side of the main board 1, and two support blocks 22 vertically disposed on opposite sides of the base block 21. The upper ends of the two support blocks 22 are provided with mounting plates 23. The drive system 2 also includes a drive motor (not shown in the figure) disposed on the upper side of the mounting plate 23, and an eccentric shaft 24 rotatably disposed on the support blocks 22 and connected to the drive motor transmission end. The mixing system 3 is connected to the eccentric shaft 24 and is configured to drive the moving test tube to complete the mixing of liquid.

[0019] Specifically, the eccentric shaft 24 is vertically arranged and includes a columnar connecting section with both ends coaxially arranged, and an eccentric section eccentrically arranged between the two connecting sections. The lower connecting section of the eccentric shaft 24 is rotatably connected to the base block 21 through a transition bearing. The transmission end of the drive motor passes downward through the mounting plate 23 and is connected to the upper connecting section of the eccentric shaft 24. The action of the drive motor can drive the connecting section to rotate, thereby driving the eccentric section to rotate eccentrically.

[0020] In this embodiment, combined with Figure 3 The mixing system 3 includes a connecting rod 32 and a test tube rack 33 located on the upper side of its middle part, which can fix the test tubes. The mixing system 3 also includes a connecting mechanism 31 located on the upper side of the main board 1. The two ends of the connecting rod are respectively connected to the connecting mechanism 31 and the transmission shaft.

[0021] Specifically, the connecting mechanism 31 includes a slide rail 311 horizontally arranged on the upper side of the main board 1, and a slider 312 slidably arranged on the slide rail 311. One end of the connecting rod 32 is rotatably connected to the slider 312, and the other end is rotatably connected to the eccentric shaft 24. Based on this structure, the action of the drive motor can drive the eccentric shaft 24 to rotate, thereby driving the eccentric rotation of one end of the connecting rod 32 connected to the eccentric shaft 24, and finally driving the test tube rack 33 on it to move, realizing the synchronous mixing of liquids in several test tubes. This method of driving several connecting rods 32 to move through the eccentric shaft 24 reduces the load on a single connecting rod 32. Combined with the action of the drive motor, several test tubes can be placed on several mixing systems 3 for mixing. Moreover, even if the test tube rack 33 (along with the test tubes and their internal liquids) on the upper part of the connecting rod 32 has a large load, the mixing of liquids can still be completed smoothly, effectively ensuring the mixing effect of liquids.

[0022] As a preferred embodiment of this example, in order to further reduce the load on the drive motor and ensure the mixing effect of the mixing device on the liquid, a fixing plate 313 is provided on the upper side of the slider 312, and a column 314 is provided vertically on the upper side of the fixing plate 313. One end of the connecting rod 32 is rotatably connected to the eccentric section of the eccentric shaft 24 through the first bearing 25, and the other end is rotatably connected to the column 314 through the second bearing 315.

[0023] In this embodiment, combined with Figure 4 As a preferred embodiment of this example, in order to facilitate the assembly and disassembly of the test tubes relative to the test tube rack 33, the test tube rack 33 includes a vertical support with an opening on its upper side, and a clamping block 333 that can clamp and fix the test tubes in the opening is movably provided on one side of the opening.

[0024] As a further preferred embodiment, to facilitate real-time observation of the mixing status of the liquid in the test tube during the mixing process, the support includes a U-shaped frame 331 with a fixing block 332 on its upper side. The U-shaped frame 331 and the fixing block 332 form a square frame structure. The opening is vertically through the fixing block 332. A spiral adjustment shaft is rotatably provided on one side of the clamping block 333. The outer end of the spiral adjustment shaft extends to the outside of the fixing block 332 and is spirally connected to the fixing block 332. By rotating the spiral adjustment shaft, the fixing block 332 can be engaged with the side of the opening away from the fixing block 332, thereby achieving the clamping and fixing of the test tube.

[0025] In a preferred embodiment, to prevent the test tube from shaking during the mixing process and to ensure the clamping and fixing effect of the test tube by the clamping block 333, the clamping side and / or the side wall of the opening of the clamping block 333 are also provided with arc notches, and when both the clamping side and the side wall of the opening of the clamping block 333 are provided with arc notches, the two arc notches are arranged opposite to each other.

[0026] Furthermore, to ensure that the mixing device can adapt to high-load operation and that a single test tube rack 33 can fix a number of test tubes at one time, multiple sets of arc notches are arranged in parallel so that multiple test tubes can be clamped and fixed at one time through the test tube rack 33.

[0027] In this embodiment, as a preferred implementation, to prevent the test tube from detaching from the test tube holder 33 during shaking, a pressure block 335 is also provided on the upper side of the fixing block 332 to restrict the upward movement of the test tube opening. Specifically, a connecting block 334 is also provided on the upper side of the fixing block 332. The connecting block 334 has a circular opening corresponding to the arc notch. The test tube can be inserted into the opening on the fixing block 332 through the opening and clamped by the clamping block 333. The pressure block 335 is correspondingly arranged on the upper side of the opening on the connecting block 334.

[0028] As a further preferred embodiment, the support between the adjacent groups of arc notches is also provided with a vertical isolation plate 336.
