[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 4The utility model provides a shaking device, including: a supporting structure and a power component.

[0026] The supporting structure includes a supporting portion 1 and a sealing portion 2, wherein the supporting portion 1 is used to support and limit the position of the container 5 to be shaken, and the sealing portion 2 is used to seal the container 5 to be shaken to prevent the internal liquid from spilling out from the container opening;

[0027] The power assembly includes a driving member 3 and a shaking body 4. The driving member 3 is specifically a driving motor, and can also be an electric cylinder or a pneumatic cylinder, etc., and a seat body for carrying the motor can be set at the bottom. The shaking body 4 is connected to the supporting structure, and is suitable for driving the supporting structure to rotate and rise and fall in the height direction under the driving action of the driving member 3.

[0028] By setting the driving member 3 and the shaking body 4, the driving member 3 provides power to realize the shaking automation and improve the work efficiency. At the same time, the driving member 3 can drive the supporting body to rotate, and the supporting body has a rise and fall change in height during the rotation process. This setting meets the up and down oscillation requirements for the liquid in the container to be shaken evenly during different experimental detection processes, and it is achieved by rotation, which is convenient for accurately setting the number of oscillations and ensuring that the number of oscillations requirements are met. In addition, by setting the sealing part 2 to seal the container, the liquid in the container can be effectively prevented from spilling.

[0029] The shaking body 4 includes: a guide assembly, a crank structure 43 and a gear assembly.

[0030] The guide assembly includes a guide member 41 and a guide slider 42 .

[0031] The guide member 41 is specifically arranged in the shape of a long rod or a long tube, preferably in the shape of a long cylinder, and its length direction is arranged vertically. Specifically, this vertical arrangement refers to the orientation of the guide member 41 when the shaking device is placed flat on a horizontal working surface. When the shaking device is moved and tilted as required, the guide member 41 is tilted accordingly. As a convertible embodiment, the guide member 41 can also be arranged to be tilted relative to the horizontal plane.

[0032] The guide slider 42 is movably connected to the guide member 41. In this embodiment, the guide slider 42 includes a first block and a second block connected to each other. The first block is in the shape of a sleeve, which is sleeved on the guide member 41, movably connected to the guide member 41 and limited in the horizontal direction, and can move along the extension direction of the two ends of the guide member 41. The second block is connected to the side of the first block and is arranged in a columnar shape. In this way, the guide slider 42 with two blocks can expand the movement space and avoid the movement of the guide slider 42 when it is connected with other structures interfering with the guide member 41.

[0033] The crank structure 43 includes two movable connecting rods hinged to each other, and the two movable ends of the two movable connecting rods are respectively connected to the driving member 3 and the guide slider 42. In this embodiment, the driving member 3 is a driving motor, which can drive the guide slider 42 to reciprocate up and down along the guide member 41. As a convertible implementation method, when the driving member 3 is an electric cylinder or a cylinder, the crank structure 43 may not be set.

[0034] The gear assembly is connected to the supporting structure and the guide slider 42 respectively, and is suitable for driving the supporting structure to reciprocate in the vertical direction under the action of the guide slider 42.

[0035] By setting up the shaking main body 4 including the guide assembly, the crank structure 43 and the gear assembly, the unidirectional rotational motion of the driving part 3 of the motor is converted into continuous forward and reverse motion with sufficient power, avoiding the use of a stepper motor. Although the forward and reverse motion can be directly set, the cost is high, and due to the high load, it is easy to cause problems such as shutdown or overload.

[0036] Specifically, the gear assembly includes a guide rack 44 , a rotating shaft 45 and a gear member 46 .

[0037] Preferably, the guide rack 44 is arranged parallel to the guide member 41 .

[0038] The rotating shaft 45 is preferably a straight shaft, and is passed through the supporting structure and the guide slider 42. The rotating shaft 45 is limitedly connected to the supporting structure, preferably detachable, and can be interference fit or screwed. The rotating shaft 45 is movably connected to the guide slider 42. A collar is provided on the top of the second block of the guide slider 42, and the rotating shaft 45 passes through the collar. The two are coaxial and can rotate relative to each other. Preferably, the rotating shaft 45 is perpendicular to the guide member 41.

[0039] The gear member 46 is coaxial with the rotating shaft 45. The rotating shaft 45 is provided on the gear member 46 and is limitedly connected with the gear member 46, such as interference fit or screw connection, or can be integrally provided. The gear member 46 has a transmission state correspondingly meshed with the guide rack 44. Preferably, in this embodiment, the gear member 46 also has a single lifting state away from the guide rack 44. The rotating shaft 45 is suitable for lifting and lowering under the drive of the guide slider 42. When the gear member 46 touches the guide rack 44 and enters the transmission state, the rotating shaft 45 drives the supporting structure to rotate synchronously.

[0040] In addition, the shaking device also includes a rotation limiter 47, which is specifically a limiter rod, which is located adjacent to the guide rack 44 and is correspondingly arranged on the side of the guide rack 44 away from the guide slider 42. The rotation limiter 47 can limit the rotation shaft 45 or the gear member 46 during the upward movement of the gear member 46 on the rotation shaft 45 relative to the guide rack 44, and prevent it from continuing to move upward. By setting the rotation limiter 47, the travel of the gear member 46 on the guide rack 44 can be limited, and the rotation angle of the supporting structure can be correspondingly adjusted.

[0041] As a convertible embodiment, the rotation limiter 47 may not be provided.

[0042] In this embodiment, in the transmission state, the rotation angle of the gear member 46 relative to the rotating shaft 45 is 180°. This arrangement allows the supporting structure to rotate 180° accordingly, making it easier for the container to be oscillated in the supporting structure to be turned upside down and effectively shaken and mixed. As a convertible embodiment, the rotation angle of the gear member 46 relative to the rotating shaft 45 can also be less than or greater than 180°, such as 90°, 120°, 150°, 210°, 240°, 270°, and 360°.

[0043] The shaking device also includes a shaking housing 48 and a guide slot 49;

[0044] The shaking shell 48 has a built-in driving member 3 and a part of the shaking body 4. The guide rack 44 and the rotation limit member 47 are both limitedly set on the shaking shell 48. Specifically, the guide rack 44 can be fixed to the inner wall of the shaking shell 48 by screwing. The guide long hole 49 is set on the outer wall of the shaking shell 48 and extends in the same direction as the guide member 41. An expansion hole can be set correspondingly at a position adjacent to the guide rack 44 for easy detection and maintenance. The rotating shaft 45 passes through the guide long hole 49 and is connected to the supporting structure outside the shaking shell 48. The guide long hole 49 can assist in guiding the movement direction of the rotating shaft 45.

[0045] As an alternative embodiment, the shaking housing 48 and the guide slot 49 may not be provided, and the guide rack 44 may be supported by only an additional single wall or a single rod.

[0046] In addition, a switch 7 for controlling the start and stop of the driving member 3 is also provided on the shaking housing 48 .

[0047] In this embodiment, the supporting portion 1 includes: a tray assembly and an adjustment assembly.

[0048] The tray assembly includes a first tray 11 and a second tray 12. The first tray 11 is suitable for supporting the bottom of the container 5 to be shaken. The second tray 12 is in the shape of a concave disc or a flat plate, and is correspondingly arranged on the top of the container 5 to be shaken. One of the first tray 11 and the second tray 12 is connected to the gear assembly, and in this embodiment, it is the second tray 12. The second tray 12 is provided with a connecting groove, which can accommodate the rotating shaft 45 of the limit gear assembly. Preferably, the first tray 11 is slightly larger than the second tray 12.

[0049] The adjusting assembly comprises an adjusting member 13, a limiting sliding sleeve 14 and an elastic member 15. The number of the adjusting members can be two or more, and they are evenly distributed along the edge of the tray assembly.

[0050] The adjusting member 13 is columnar and is correspondingly arranged on the first tray 11, or the second tray 12. The limiting sleeve 14 is correspondingly arranged on the second tray 12, or can be correspondingly arranged on the first tray 11 when the adjusting member 13 is arranged on the second tray 12. The adjusting member 13 passes through the plane where the first tray 11 and the second tray 12 are located in the length direction. In this embodiment, the adjusting member 13 is arranged at the edge of the first tray 11 and is adjacent to the edge of the second tray 12. The limiting sleeve 14 is arranged at the edge of the second tray 12 and is correspondingly sleeved on the adjusting member 13. The limiting sleeve 14 and the adjusting member 13 are movably connected, and the two can move relative to each other. The tensioner 15 is specifically a fixing screw, which is passed through the limiting sleeve 14 and can be tightened or loosened with the adjusting member 13, and can be manually adjusted by the user to limit or loosen the adjusting member 13 and the limiting sleeve 14.

[0051] Preferably, the first tray 11 and the second tray 12 are arranged in parallel. Such an arrangement facilitates batch clamping of multiple containers to be oscillated with uniform or similar heights. In addition, preferably, the adjustment member 13 is perpendicular to the first tray 11 and the second tray 12. As a convertible embodiment, the second tray 12 can also be a tray with multiple grooves or protrusions to limit the positions of containers to be oscillated of different models.
