Preferably, the radius of the groove is 3.4-3.5 cm.

Preferably, the depth of the groove is 0.7-0.9 cm.

The beneficial effects of the utility model reside in that:

1. by adding the push-pull type containing tray on the basis of the original test tube rack, the problem that the existing test tube rack cannot contain the test tube cover is solved, the experimental space is saved, and the pollution caused by the test tube cover in the experimental process is avoided; increase the serial number on original test-tube rack basis, solve the problem that the test tube lid thoughtlessly covered, avoided when test tube quantity is more because thoughtlessly cover the test tube lid and lead to reagent purity to change.

2. The utility model discloses a test-tube rack passes through the flexible of telescopic link, gets up the test-tube rack shrink, reduces the height, is convenient for place of comparatively short little test tube, does not occupy great space simultaneously relatively. Is convenient for arrangement in a laboratory.

Detailed Description

The invention is described in further detail in with reference to specific embodiments and with reference to the drawings it is emphasized that the following description is merely exemplary and not intended to limit the scope of the invention and its applications.

Example 1

improved test tube rack capable of accommodating test tube covers, which comprises an upper layer 1 and a middle layer 2, wherein a pull-out tray 3 is arranged below the middle layer 2 of the test tube rack, the pull-out tray 3 is connected with a slot 33 on the test tube rack in a sliding way, and the upper layer 1 and the middle layer 2 are connected and fixed through a telescopic rod 4.

The telescopic rod 4 comprises an outer rod 41, an inner rod 42, a protrusion 43, an elastic sheet 44 and an th small hole 45.

The inner rod 42 is connected with the middle layer 2, the outer rod 41 is connected with the upper layer 1, the outer rod 41 is arranged outside the inner rod 42, the th small hole 45 is formed in the outer rod 41, and the protrusion 43 and the elastic sheet 44 are arranged on the inner rod 42.

The upper layer 1 of the test tube rack is provided with a large hole 11 for placing a test tube and a second small hole 12, the aperture of the large hole 11 is 2.9cm, and the aperture of the second small hole 12 is 1.8 cm.

The middle layer 2 of the test tube rack is provided with a support hole corresponding to the upper layer 1.

Test tube jack setting and the serial number that the recess of accomodating the tray corresponds.

The drawing tray is provided with a circular shallow groove 31 corresponding to the insertion hole of the test tube.

The radius of the groove 31 is 3.4 cm.

The depth of the groove 31 is 0.7 cm.

When the test tube on the test-tube rack is used to needs, pull earlier little baffle and will accomodate tray 3 and pull out, open again and wait to use the test tube and invert the tube cap and make the roof place down in accomodating tray recess 31 that corresponds with this test tube serial number, at last with the tray push the test-tube rack can.

In the using process, the test tube rack stretches the telescopic rod, and the protrusion 43 is fixed in the th small hole 45 to prevent the sliding.
