Height-adjustable pre-freezing metal rack for semen cryopreservation

The present invention relates to a height-adjustable pre-freezing metal rack for semen cryopreservation, comprising a metal mesh (1), serrated blocking edges (9), a rack body (2), rack body sliding blocks (4), rack body supporting legs (6) and handles (10). The baffles (8) are arranged at two ends of the metal mesh (1); baffles (8) are fixedly connected to the rack body sliding blocks (4) through bolts, the serrated blocking edges (9) are arranged on the two side edges of the metal mesh (1), two ends of the rack body (2) are fixedly connected with the rack body sliding blocks (4), the rack body supporting legs (6) are sleeved with the rack body sliding blocks (4), and a plurality of rack body height adjusting holes (5) are formed in the rack body supporting legs at equal intervals. The handles (10) are fixed on the rack body sliding blocks (4); and limiting blocks (7) are arranged on the rack body supporting legs (6). The height of the pre-freezing metal rack can be flexibly adjusted, the metal mesh is adopted to replace an existing washboard, and tubules are not prone to falling off.
