DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-Figure 2 As shown, the utility model provides a drain rack, comprising: a base 1, side holes 11 are provided on both sides of the base 1, the height of the side holes 11 can accommodate a volumetric flask and a conical flask into the base 1, and a volumetric flask rack 3 is arranged in the base 1.
[0025] Specifically, the volumetric bottle rack 3 includes a slide bar 31, which is fixedly installed in the base 1. The slide bar 31 is slidably connected to a slide plate 32. A moving channel 33 is arranged between two slide plates 32 in the same horizontal plane. The slide plate 32 can be removed from the slide bar 31 and replaced with slide plates 32 of different widths, so that the width of the moving channel 33 is adapted to volumetric bottles or conical bottles of different calibers.
[0026] In this embodiment, the cleaned volumetric flask or conical flask is turned upside down with the bottle mouth facing downward. Since the bottle mouths of the conical flask and the volumetric flask are inwardly retracted, the volumetric flask or conical flask can be stuck in the moving channel 33, and the liquid in the bottle flows out from the bottle mouth under the action of gravity to achieve drainage.
[0027] like Figure 1 As shown, a pipette rack 6 with a disc-shaped structure is detachably connected to the top of the base 1, and the disassembly methods include but are not limited to snap-fitting and magnetic attraction. Preferably, a magnetic attraction method is adopted, and a magnetic attraction strip is arranged between the pipette rack 6 with a plurality of tube holes 61 and the base 1, and the magnetic attraction strip is bonded to the top of the base 1. The pipette rack 6 is made of metal material to facilitate magnetic attraction. By replacing the pipette rack 6 with different tube holes 61 diameters, it can be adapted to pipettes or glass rods of different specifications.
[0028] like Figure 1 , Figure 4 As shown, a beaker rack 5 is fixed to the front of the base 1, and the beaker rack 5 includes a connecting arm 51, one end of the connecting arm 51 is fixedly mounted on the base 1, and two supporting arms 52 are fixedly mounted on the other end of the connecting arm 51, and the supporting arms 52 are at an angle of 45° to the horizontal plane. The beaker is turned upside down and put outside the two supporting arms 52, so that the beaker is tilted, which is convenient for the discharge of residual liquid in the beaker.
[0029] like Figure 1 , Figure 5 As shown, a drain pan 4 is arranged below the beaker rack 5 , and the drain pan 4 is used to store liquid flowing out from the pipette rack 6 and the beaker rack 5 .
[0030] Specifically, the drain tray 4 includes a water storage box 41 , which is fixedly mounted on the base 1 . The water storage box 41 is fixedly mounted with an inclined plate 42 . The inclined plate 42 is fixedly mounted on the inner wall of the base 1 , and the inclined plate 42 is located below the pipette rack 6 .
[0031] like Figure 1 , Figure 3 As shown, a pipette gun rack 2 is arranged below the drain tray 4, and the pipette gun rack 2 is fixedly mounted on the base 1. The pipette gun rack 2 has a strip hole 21, and the strip hole 21 is slidably connected with a clamping ring 22. The clamping ring 22 is provided with a buckle 23 adapted to the pipette gun rack 2. The hanging part of the pipette gun is clamped into the clamping ring 22, so that the pipette gun is in an upside-down state. The spacing and number of the clamping rings 22 can be adjusted to drain water from different volumes or multiple pipette guns at the same time.
[0032] In this embodiment, the liquid drained from the beaker on the beaker rack 5 is received by the drain pan 4 in the water storage tank 41, the pipette and the glass rod pass through the tube hole 61 on the pipette rack 6 and are supported by the inclined plate 42, and the liquid dripping from the pipette and the glass rod flows into the water storage tank 41 along the inclined plate 42, and the drain pan 4 receives the liquid flowing down the beaker rack 5 and the pipette rack 6 to prevent the liquid from dripping onto the pipette gun below and causing cross contamination.
[0033] It can be understood that the use of the drain rack in the present application can reasonably place a variety of experimental instruments on the same drain rack. Placing multiple instruments on the drain rack can improve the space utilization of the drain rack. There is no need to place multiple drain racks in a micro-laboratory or a laboratory with a small number of experimental instruments, which also reduces the floor space occupied by the drain rack in the laboratory.
[0034] Working principle: the pipette can be stuck on the pipette rack 2 for hanging and draining, the volumetric flask and the conical flask are inverted on the volumetric flask rack 3 for draining, the beaker is inverted on the beaker rack 5, the pipette and the glass rod pass through the pipette rack 6 and are supported by the drain tray 4, and the liquid flowing down the beaker rack 5 and the pipette rack 6 is received by the drain tray 4.
[0035] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
