Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1~4 , in an embodiment of the present invention, a foldable test tube rack with good stability includes a bottom plate 1, and four corners of the bottom of the bottom plate 1 are provided with fixing devices, and the fixing devices include a cylinder 11, a spring 12, a piston 13. Piston rod 15 and suction cup 17. The cylinder body 11 is mounted on the bottom of the base plate 1 by screws. The cylinder body 11 is provided with a piston 13. Th...

Abstract

The invention discloses a foldable test tube stand with high stability. The foldable test tube stand comprises a base plate, a fixed device, a threaded rod, a sleeve, a supporting rod, a sliding block, placing plates, an arc-shaped plate and a spring, wherein the fixed device comprises a cylinder block, a spring, a piston, a piston rod and a sucking disc. The foldable test tube stand is provided with the fixed device, due to the action of gravity, the base plate drives the cylinder block to move downwards, the piston moves upwards relative to the cylinder block, the space, positioned at the lower part of the piston, inside the cylinder block is increased, and negative pressure is generated, the negative pressure is generated inside the sucking disc, and the whole test tube stand is suckedon a desk, so that the stability of the device is greatly improved; the foldable test tube stand is provided with the threaded rod, the sleeve, the supporting rod and the placing plates, when a test tube needs to be placed, the threaded rod is rotated through the sucking disc, the threaded rod drives the sleeve to move upwards, the sleeve drives the ends of the placing plates to move upwards through the supporting rod until all the placing plates are unfolded, and when the test tube stand doest not need to be used, the threaded rod is rotated in opposite direction, and the placing plates can be folded, so that the space of the desk is saved, and the operation of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a foldable test tube rack with good stability. Background technique [0002] Test tubes, commonly used instruments in chemical laboratories, are used as reaction containers for a small amount of reagents, and are used at room temperature or when heated. Test tubes are divided into ordinary test tubes, support test tubes, centrifuge test tubes and so on. [0003] 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. [0004] The function of the current test tube rack is relatively single. Generally, when not in use, it also takes up a large space in the working week. It does not have a folding function and is inconvenient to use. Contents of the invention [0005] The purpose of the...
