To achieve stable support and lifting of the column, the traditional design often uses multiple sets of support assemblies, each set of assembly is equipped with an independent power device. During the subsequent maintenance of the equipment, due to the large number of power devices, any failure of a unit requires professional technicians to spend a lot of time to troubleshoot and repair, and the cost of repair parts and labor cost cannot be underestimated, which greatly increases the economic burden of the using unit.

DETAILED DESCRIPTION

[0023] In the utility model, in the case where no opposite statement is made, the orientation such as "upper, lower" is usually for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is usually for the left and right shown in the drawing; "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0024] The utility model provides a technical scheme:

[0025] Please refer to Figures 1 to 3 The equipment mainly comprises base 1, fixed ring 2, support frame 3 and column 4. Base 1 is the root of the whole device, provides stable support for the components above, ensures that the equipment does not shake or displace during operation, which is crucial for column chromatography experiments that require high precision separation.

[0026] Support frame 3 connects base 1 and fixed ring 2, which not only has enough mechanical strength to bear the weight of fixed ring 2 and other components installed subsequently, but also considers the force distribution in the structural design, so that the overall equipment is evenly stressed, prolonging the service life.

[0027] Fixed ring 2 is the key hub of the equipment, and the annular cavity 5 is carefully designed inside. The rotating ring 8 and the drive motor 9 are integrated in the annular cavity 5, and the two work cooperatively through a specific rotating mechanism. The rotating mechanism is composed of the driving gear 10 installed on the output shaft of the drive motor 9 and the driving gear ring 11 on the rotating ring 8 that meshes with it. When the drive motor 9 starts, the driving gear 10 rotates, and through the meshing action with the driving gear ring 11, it drives the rotating ring 8 to rotate smoothly in the annular cavity 5. This design makes the power transmission efficient and accurate, providing reliable initial power for the subsequent lifting action of the column 4.

[0028] At the same time, the transmission shaft 14 is also provided in the annular cavity 5, which is stably installed through the fixed frame 13, ensuring that it does not deviate during operation. The transmission shaft 14 and the rotating ring 8 are linked through a transmission mechanism, which includes the transmission gear 15 installed on the transmission shaft 14 and the transmission gear ring 12 on the rotating ring 8 that meshes with it. With the rotation of the rotating ring 8, the transmission gear 15 drives the transmission shaft 14 to rotate synchronously under the action of the transmission gear ring 12, further transmitting power to the subsequent components.

[0029] At the end of power transmission, the engaging gear 17 is ingeniously arranged on the fixed frame 13, and the transmission shaft 14 is connected with the engaging gear 17 through the engaging mechanism. The engaging mechanism is specifically composed of the linkage gear 16 mounted on the transmission shaft 14 (designed as a bevel gear to adapt to the specific transmission angle requirement) and the engaging gear 17 (also a bevel gear to ensure precise engagement with the linkage gear 16). When the transmission shaft 14 rotates, the linkage gear 16 drives the engaging gear 17 to rotate.

[0030] In order to realize the lifting function of the column body 4, the positioning wheel 7 is rotatably mounted on the fixed ring 2 through two fixed plates 6, and the positioning wheel 7 is connected with the engaging gear 17 through the synchronous mechanism. The synchronous mechanism is composed of two synchronous pulleys 18 mounted on the fixed frame 13 and connected with the engaging gear 17 and mounted on the positioning wheel 7, and the two synchronous pulleys 18 are connected through the synchronous belt 19. When the engaging gear 17 rotates, the synchronous pulley 18 and the synchronous belt 19 are cooperated to drive the positioning wheel 7 to rotate synchronously.

[0031] It is worth mentioning that the positioning wheel 7 is equipped with a rubber protective ring, and the anti-skid pattern design on the surface of the rubber protective ring can not only effectively prevent the column body 4 from sliding during lifting, but also avoid scratching the surface of the column body 4, ensure the integrity and stability of the column body 4, and further ensure the smooth progress of the column chromatography experiment.

[0032] Specifically, the working principle of the utility model is as follows:

[0033] Firstly, when the equipment starts, the driving motor 9 in the annular cavity 5 of the fixed ring 2 starts to work, and the driving gear 10 on the output shaft of the driving motor 9 rotates. Since the driving gear 10 is engaged with the driving gear ring 11 on the rotating ring 8, the rotating ring 8 is driven to rotate smoothly in the annular cavity 5. With the continuous rotation of the rotating ring 8, the transmission gear 15 drives the transmission shaft 14 to rotate synchronously under the action of the transmission gear ring 12. Then, the linkage gear 16 (designed as a bevel gear to adapt to the transmission angle requirement) on the transmission shaft 14 is precisely engaged with the engaging gear 17 which is also a bevel gear, and when the transmission shaft 14 rotates, the linkage gear 16 drives the engaging gear 17 to rotate. At this time, the synchronous pulley 18 matched with the synchronous belt 19 can finally drive the positioning wheel 7 to rotate, as shown in the figure, the four positioning wheels 7 press and fix the column body 4 in the middle, and with the rotation of the positioning wheel 7, the stable lifting of the column body 4 is realized. Moreover, the rubber protective ring on the positioning wheel 7 and the anti-skid pattern design can effectively prevent the column body 4 from sliding during lifting and avoid scratching the column body 4, and ensure the smooth progress of the entire column chromatography experiment.

[0034] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
