Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a test tube rack convenient to store comprises a base 3, a supporting column 4 is vertically arranged in the middle of the rear half part above the base 3, the cross section of the supporting column 4 is a U-shaped groove, the opening of the U-shaped groove faces the inner side of the base 3, an opening is formed in the rear wall of the groove in the middle upper part of the supporting column 4, a sleeve 65 is coaxially arranged on the outer side of the rear wall of the groove in the opening, an end plate 66 is arranged at the other end of the sleeve 65, the sleeve 65 is connected with a positioning tube 63 through the end plate 66, a rotating rod 62 penetrates through the opening, one end of the rotating rod 62 is fixedly connected with a cross frame 5, the other end of the rotating rod penetrates through the opening in the rear wall of the groove, the sleeve 65, the end plate 66 and the positioning tube 63 are connected with a hand wheel 61, a blocking rod 64 is correspondingly arranged on an; an upper chute 31 and a lower chute 32 are horizontally arranged in the box body at the front half part of the base 3, the upper chute 31 and the lower chute 32 are respectively provided with a left sliding plate 2 and a right sliding plate 8 in a sliding manner, and one ends of the left sliding plate 2 and the right sliding plate 8 far away from the base 3 are respectively provided with a left support plate 1 and a right support plate 7.

The transverse frame 5 is provided with a test tube hole 51 for placing a test tube. For holding test tubes.

The rotating rod 62 is arranged in the middle of the cross frame 5, and the distance from the upper plane of the base 3 to the center of the rotating rod 62 is more than half of the length of the cross frame 5. When the rotating rod 62 is rotated, the base 3 does not interfere with the rotation of the cross frame 5 and the cross frame 5 does not interfere with the entry of the cross frame 5 into the U-shaped groove of the post 4.

The height of the left support plate 1 is matched with the height from the upper plane of the left sliding plate 2 to the bottom of the cross frame 5. This enables the left brace 1 to function as a support for the cross brace 5.

The height of the right support plate 7 is matched with the height from the upper plane of the right sliding plate 8 to the bottom of the cross frame 5. This enables the right brace 7 to function as a support for the cross member 5.
