Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example (b):

as shown in fig. 1-4:

as shown in FIG. 1, a liquid discharging tube 2 is arranged at the lower end of the chromatographic column 1 for discharging liquid in the chromatographic column 1, and a liquid discharging valve 3 is mounted on the liquid discharging tube 2 for controlling the on-off of the liquid discharging tube 2.

During the use 1 vertical placing of chromatography column, 4 both ends of guide rod are fixed respectively in 1 upper and lower both ends lateral wall of chromatography column, and balancing weight 5 is the vertical straight line slip under the guide of guide rod 4.

The two ends of the knocking rod 6 are fixedly connected with the rubber hammer 7 and the balancing weight 5 respectively, the knocking rod 6 is made of elastic materials, the rubber hammer 7 is attached to the outer side wall of the chromatographic column 1 in a normal state, the rubber hammer 7 is driven to be away from the chromatographic column 1 by external force and then loosened, and the rubber hammer 7 continuously knocks the chromatographic column 1 within a period of time due to elastic deformation of the knocking rod 6;

simultaneously, under the guide of 5 gravity of balancing weight and guide pole 4, the vertical straight line gliding of balancing weight 5 for rubber tup 7 strikes the 1 lower extreme of chromatography post from 1 upper end of chromatography post.

As shown in fig. 2, the knock bar 6 has a spiral structure, and is strong in elastic deformability and not easily broken.

As shown in fig. 3, the guide rod 4 is of a cylindrical structure, and the counterweight 5 can vertically lift under the guide of the guide rod 4, and the counterweight 5 can rotate relative to the guide rod 4; a guide groove 41 with a spiral structure (S-shaped structure) is formed between the upper end and the lower end of the outer side wall of the guide rod 4, a guide ball 53 is arranged in the balancing weight 5, and the guide ball 53 rolls along the track of the guide groove 41 in the guide groove 41 relatively, so that the balancing weight 5 can simultaneously rotate back and forth in a reciprocating manner in the vertical lifting process relative to the guide rod 4 under the matching of the track of the guide groove 41 and the guide ball 53;

the counterweight 5 rotates a certain angle relative to the guide rod 4, namely, the knocking rod 6 is driven to elastically deform a certain angle; therefore, in the process that the balancing weight 5 moves downwards from the upper end of the chromatographic column 1 and rotates in a reciprocating mode, part of gravity is converted into elastic deformation force of the knocking rod 6, and the rubber hammer head 7 can strike the chromatographic column 1 evenly from top to bottom.
