Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Example (b): as shown in fig. 1-3, an adjustable test tube rack for water bath is used for fixing small-capacity experimental containers such as ampoules and the like, and can be placed in a water bath for constant-temperature heating. This test-tube rack for water bath with adjustable includes that four middle sections have stand 1, four connecting rods 2 and the tray 3 of external screw thread, and 1 lower extreme of stand is connected with stabilizer blade 11, and stabilizer blade 11 connects at the lower terminal surface of stand 1 through the screw is twisted, can finely tune the height of stand 1 through rotatory stabilizer blade 11 to realize tray 3's levelness and adjust. The bottom surface of the knob 43 is provided with an anti-slip rubber layer, so that the test tube rack can be prevented from slipping when being placed on a water bath kettle or a table top.

The connecting sections of the four connecting rods 2 are connected with lantern rings 21 which can be sleeved on the stand columns 1, the lantern rings 21 can rotate around the stand columns 1, the stand columns 1 are sequentially connected through the connecting rods 2 to form a quadrangle, and the four stand columns 1 form a parallelogram. In order to fix the collar 21 at a certain height on the column 1 and at the same time to be freely rotatable around the column 1, the following two ways can be selected. The first is that an annular groove is arranged at the same height position of the upright post 1, the diameter of the lantern ring 21 is slightly smaller than the outer diameter of the upright post 1 and slightly larger than the outer diameter of the groove, and the lantern ring 21 is clamped in the groove. Of course, two upper and lower annular grooves may be provided, and the two links 2 at opposite sides are installed in the grooves at the same height. Another way to facilitate the machining is to weld a raised ring along the outer wall at the same location of the column 1, where the outer diameter of the collar 21 is set slightly larger than the outer diameter of the column 1. When not in use, the upright post 1 with the parallelogram structure can be folded along the opposite angle and flattened and stored in the drawer without occupying a large amount of space.

Tray 3 includes frame 31, and frame 31 bottom surface connecting beam installs elastomer 32 in the frame 31, and elastomer 32 can select for use elastic rubber, pearl cotton, sponge, silica gel etc. to have elastic material, is equipped with a plurality of container holes 321 that are used for inserting the ampoule on the elastomer 32, when electing and using waterproof material, will reserve some water holes on elastomer 32 to reduce buoyancy. The container hole 321 is provided with a number on one side for marking different samples. The four corners of the frame 31 are connected with height adjusting devices 4 which can be sleeved on the upright post 1, and each height adjusting device 4 comprises an inner ring 41, a bearing 42 and a knob 43. The inner ring 41 is welded at four corners of the frame 31, a bearing 42 is installed on the outer wall of the inner ring 41, and the inner ring of the bearing 42 is fixed with the inner ring 41. The knob 43 is hollow, the inner wall of the knob is provided with internal threads matched with the external threads of the upright post 1, the upper part of the knob 43 is provided with a groove, the inner diameter of the groove is larger than that of the upright post 1 and is slightly smaller than the outer ring of the bearing 42, and the outer ring of the bearing 42 is arranged on the knob 43 through interference fit. After the tray 3 is sleeved on the four upright posts 1, the upright posts 1 are rectangular, and the knob 43 is rotated to descend along the threads on the upright posts 1 to drive the tray 3 to descend. In order to facilitate the rotation of the knob 43, the outer wall of the knob 43 is provided with anti-slip stripes.

The upright post 1, the connecting rod 2 and the tray 3 are made of stainless steel, can be erected in a water bath by the weight of the upright post, and are not easy to rust.

This embodiment the adjustable test-tube rack for water bath, during the use, support stand 1 on the desktop, form the quadrangle. When preparing a sample, the tray 3 is placed on a table top, the four knobs 43 play the role of the support legs 11, and a layer of plastic can be additionally arranged on the bottom surface of each knob 43 to serve as an anti-skid layer. The prepared sample bottles are then inserted one by one into the container holes 321 in the tray 3, and after the samples are mounted, the four height adjusting devices 4 of the tray 3 are inserted into the four columns 1. The four knobs 43 are sequentially rotated to adjust the tray 3 to a suitable height. Thereafter the whole test tube rack is placed in a water bath and the height of the tray 3 is fine-tuned according to the water level. The test tube rack is very suitable for fixing small-capacity experimental containers such as ampoule bottles and the like, and the container height is convenient to adjust and very practical. After the use, take off tray 3, later with stand 1 flat, can accomodate it in the drawer, compare general test-tube rack and save space.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
