Portable test tube rack used for drug detection and capable of preventing toppling-over

Abstract

The invention discloses a portable test tube rack used for drug detection and capable of preventing toppling-over, belonging to the technical field of test tube racks. The portable test tube rack comprises a fixing block, wherein an adjusting mechanism is arranged in the fixing block; one end of the adjusting mechanism penetrates through the outer surface of the fixing block and is fixedly connected with a positioning mechanism; the lower surface of the positioning mechanism is detachably connected with supporting mechanisms; and an anti-falling mechanism is arranged in the fixing block and located on the lower side of the adjusting mechanism. According to the invention, the multiple supporting mechanisms are arranged, so different test tubes can be stored on the multiple supporting mechanisms; a threaded column can be controlled to rotate through a first rotating shaft by rotating a screwing block, an adjusting plate can move up and down to adjust the position of the adjusting plate under the action of a threaded hole at the time, and a through hole and a positioning hole can be staggered at the moment; a silica gel pad can get close to a fixing rod and can clamp test tubes with different thicknesses at the same time; and the adjusting plate can stably move up and down along a track under the action of a first sliding block and a first sliding groove.

Description

technical field [0001] The invention belongs to the technical field of test tube racks, and in particular relates to a portable drug testing test tube rack which prevents tipping. Background technique [0002] The test tube rack is a kind of chemical experiment instrument. Wooden shelf or bamboo shelf, with 6 holes and 12 holes. The test tube rack is the most basic experimental instrument in the chemical laboratory used to place (sometimes the test tube can also be placed on the test tube rack to observe the phenomenon of a certain experiment) and dry the test tube. A corresponding number of small wooden columns and small holes are attached to the test tube rack. If there is a small hole, the test tube can be placed upright for use or in order to continue to observe the progress of the reaction. If there is a column, the clean test tube can be turned upside down for drying. [0003] The existing test tube rack is large in size, so it is very inconvenient to carry. If the...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing test tube rack is large in size, it is very inconvenient to carry, if the test tube rack is squeezed, it will easily cause the test tube rack to break, which will affect the storage of test tubes, and at the same time, there are too many test tube racks All the holes are gathered together, so the test tubes are easy to be confused when placed, which is not conducive to the identification and use of medicines. At the same time, the holes on the test tube rack are all the same size and cannot achieve a reasonable fixing effect on test tubes of different thicknesses. The placement of test tubes has caused some inconvenience, and the proposed test tube rack for portable drug testing that prevents dumping
