Fig. 1 is a structural diagram of the present utility model.

Description of the embodiments

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, the blocking agent chromatographic column placement frame comprises a base 1, lifting legs 2, a supporting seat 3 and hoop clamps 4, wherein the lifting legs 2 are vertically fixed on the base 1, the supporting seat 3 is fixed on the lifting legs 2, a plurality of clamping grooves 31 are formed in the supporting seat 3, a U-shaped clamping plate 32 is fixed in each clamping groove 31, the hoop clamps 4 are fixedly connected to the outer wall of the blocking agent chromatographic column, the blocking agent chromatographic column is inserted into the U-shaped grooves of the U-shaped clamping plate 32, and the hoop clamps 4 are supported on the U-shaped clamping plate 32.

After the blocking agent chromatographic columns are placed in each clamping groove 31, in order to better position the blocking agent chromatographic columns in each clamping groove 31, the utility model arranges the same positions of the upper end surfaces of the two sides of the U-shaped clamping plate 32 with the positioning step surfaces 321 protruding upwards. Through the positioning step surface 321, the positioning on the plane of the hoop clamp 4 can be realized, and the hoop clamp 4 is prevented from being separated from the U-shaped groove of the U-shaped clamping plate 32 in the plane direction.

The supporting seat 3 is a U-shaped seat structure with two side edges and a middle edge, the U-shaped opening direction of the supporting seat 3 is the same as the U-shaped opening direction of the U-shaped clamping plate 32, a plurality of partition boards 33 parallel to the side edges of the supporting seat are fixed on the middle edge of the supporting seat 3, and the clamping grooves 31 are formed between the adjacent partition boards 33 and between the partition boards and the side edges of the supporting seat.

The hoop clamp 4 comprises hoop sheets and butterfly bolts, one ends of the two hoop clamps 4 are hinged with each other, and the other ends of the two hoop clamps are fixed through the butterfly bolts. One end of the butterfly bolt is hinged to one of the anchor ear pieces, an opening groove for connecting the butterfly bolt in a penetrating way is formed in the other anchor ear piece, and the two anchor ear pieces are connected quickly by rotating the butterfly bolt.
