[0037] The specific implementation of the sample solution oscillating mixing device of the present invention is described in detail below with reference to the accompanying drawings.

[0038] See attached Figure 1 , 2 The sample solution oscillating mixing device includes a counterweight base 1, which has a certain weight to make the entire device stable during operation, or the counterweight base 1 can be fixed to a fixed object. One side of the counterweight base 1 is an inclined surface 2, and the angle of the inclined surface 2 is selected from 45° to 60°. Two slide rails 3 are arranged along the inclined surface 2, and the two slide rails 3 are arranged on both sides of the inclined surface 2 to reduce the overall size. The counterweight base 1 is connected to the shock absorber 4 through the mounting plate 5 below. There are four shock absorbers 4, which are respectively installed at the four corners below the counterweight base 1.

[0039] A driving motor 6 is arranged on the opposite side of the inclined surface 2 . The motor shaft of the driving motor 6 is perpendicular to the inclined surface 2 . The motor shaft passes through a through hole arranged on the inclined surface 2 . A cam 7 is arranged on the motor shaft.

[0040] A disc rack 8 is arranged on the slide rail 3 of the inclined surface 2, and two sliders 9 are respectively arranged on the disc rack 8, and the sliders 9 are respectively matched on the slide rail 3. A container rack 10 is installed on the disc rack 8, and a container 11 is arranged on the container rack 10. The container 11 is arranged vertically on the container rack 10. The cam 7 on the motor shaft is connected to the disc rack 8 through a connecting rod 12, and the cam 7 drives the disc rack 8 to move back and forth on the slide rail 3 along the inclined surface.

[0041] A plurality of weight-reducing holes 13 are provided on the disc rack 8 and the cam 7 to reduce the load of the motor when it is working, and a photoelectric sensor 14 is provided on one side of the slide rail 3 to locate the moving position of the disc rack 8. The positioning by the photoelectric sensor 14 makes the movement of the disc rack 8 within a controllable range.

[0042] See attached Figure 3 The container rack 10 is mounted on the disk rack 8 through a supporting member. A bottom plate 15 is provided at the bottom of the container rack 10, and a container positioning hole 16 is provided on the bottom plate 15. An array of container arrangement holes 17 are provided on the container rack 10, and a pressing piece 18 is provided on the container arrangement hole 17. The pressing piece 18 includes a fixing ring 19 fixed to the edge of the container arrangement hole 17, and an elastic pressing tongue 20 extending upward is provided on the fixing ring 19. A plurality of tension springs 21 are provided on the container rack 10, and the tension springs 21 are tensioned on the support bars 22 on both sides of the container rack 10, and the tension springs 21 are arranged horizontally or vertically just above the container arrangement hole 17 on the container rack 10.

[0043] The container rack 10 on the tray 8 can be replaced with containers 11 of different sizes, such as various centrifuge tubes. After the reagent is injected into the container 11, the container 11 is tightly covered, and the container 11 is placed on the container rack 10. The tension spring 21 is installed to prevent the container 11 from being thrown out during the oscillation. Then the motor is started, and the appropriate speed is adjusted. The cam 7 on the motor shaft makes the tray 8 reciprocate on the slide rail 3 through the connecting rod 12, and the container 11 is pulled and swung obliquely to achieve the vibration effect of both the horizontal and vertical directions, so that the reagents in the container 11 are mixed more thoroughly. At the same time, the load of the motor is also decomposed by the inclined surface, which reduces the pressure on the motor.

[0044] The invention is applied to the processes of solution mixing, centrifugal pretreatment and the like in chemical laboratories, and the mixing effect is obviously higher than that of the mixing in the horizontal vibration mode.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
