Description

Multi-pipe vortex mixer convenient for taking and placing pipe frame

Technical Field

The utility model relates to the field of detection equipment, in particular to a multi-pipe vortex mixer convenient for taking and placing a pipe frame.

Background

The multi-tube vortex mixer is a laboratory detection matching device which skillfully combines oscillation and vortex, and can be used for simultaneously carrying out vortex oscillation on various samples. Before the operation, generally need be equipped with the test tube of different samples with a plurality of cartridge respectively in the hole of the test-tube rack of making by foam or sponge, then place on the vibration platform of swirl mixer main part, again will be equipped with the pressure cover plate of making by foam or sponge pipe support upper cover and compress tightly downwards hard, the tight knob top on the slip post of reuse both sides is tight, start the vibration again. After oscillation, the tight knob is loosened manually, the upper cover of the pipe frame and the gland plate are jacked up, the test-tube frame is taken out, and the placing and taking of the test-tube are inconvenient at each time. Although improvements in this compact structure are also desirable, such as: patent technology "… that" a swift closing device of upper cover's multitube swirl mixing appearance "that grant notice number is CN213761542U when using, according to the test tube specification, the height of the fixed cover of height adjustment, the test tube that will carry out the mixing again embolias the test tube cover, then push down the test tube, along with the test tube descends, upper cover A, upper cover B is constantly rotatory, finally, when upper cover A, upper cover B covers the test tube lid, push down upper cover A, upper cover B, afterwards, with the buckle, fixed protruding lock can accomplish test tube and upper cover A, upper cover B's is fixed. After the mixing is completed, the retaining ring is opened, the upper cover A and the upper cover B are rotated, the test tube sleeve is lifted, and finally the test tube is taken out … ″, and the test tube is pressed by rotating, covering and pressing the two upper covers A and B which are respectively turned over in the technical scheme.
