fig. 2 is a schematic view of the structure of the case cover of the present invention.

Detailed Description

The invention will be further elucidated with reference to the drawing.

As shown in fig. 1 and 2, a light-resistant test tube rack assembly capable of being heated in a water bath includes a box cover 2 and a box body 1 with an open side, wherein the open side of the box body 1 is designed, the upper end of the box body 1 is connected with the box cover 2, the box cover 2 and the box body 1 are movably connected through a rotating shaft 9 (or the box cover 2 is hinged or the box cover 2 is separated from the box body 1), and the rotating box cover 2 can cover the upper surface of the box body 1. A plurality of pairs of sliding grooves 11 are formed in two opposite side surfaces in the box body 1, a first placing frame 3 is connected in the box body 1 in a sliding mode through the sliding grooves 11, the first placing frame 3 is movably connected with the box body 1, the height can be adjusted to adapt to test tubes with different heights by placing the test tubes in the sliding grooves 11 with different heights, a plurality of test tube placing holes 31 are formed in the first placing frame 3, the test tubes can be placed in the test tube placing holes 31, the test tubes with different sizes and diameters can be matched with the plurality of first placing frames 3, and different first placing frames 3 can be selectively used when the test tubes with different heights, diameters and sizes are required to be heated in a water bath; a second placing rack 4 is arranged below the first placing rack 3 and connected with the box body 1 in a sliding mode, a plurality of test tube supporting holes 41 are formed in the second placing rack 4, the test tube supporting holes 41 correspond to the test tube placing holes 31 in a one-to-one mode, the diameters of the test tube supporting holes 41 are smaller than the diameter of the test tube placing holes 31, when the diameters of the test tube supporting holes 41 are set to be smaller than the diameter of a placed test tube, the test tube is supported by two layers of plates of the first placing rack 3 and the second placing rack 4 in the box body 1, and the position is stable and not prone to toppling; when the diameter of test tube supported hole 41 set to be less than the diameter of placing the test tube, the test tube was placing in the test tube placed hole 31, and the test tube bottom supports in the test tube supported hole 41 of second rack 4 to the test tube main part is located the test tube and places between hole 31 and the test tube supported hole 41, and the test tube can be more steady and make things convenient for personnel to observe.

As shown in fig. 1 and 2, in order to prevent the cover of the test tube from being opened by the expanded gas inside when the test tube is heated, a compressing block 5 is arranged at a position of the box cover 2 corresponding to the test tube placing hole 31, the compressing block 5 is detachably connected with the box cover 2, the compressing block 5 can be selectively used according to the number and the position of the test tubes and can select compressing blocks 5 with different elasticity and sizes, the compressing block 5 is a spring (or compressing bumps such as a rubber block or a sponge block, and the like), when the box cover 2 is covered on the box body 1, the spring is positioned above the corresponding test tube placing hole 31 (the height of the first rack 3 and the second rack 4 can be adjusted to enable the distance between the test tube cover and the spring to be in a proper position), the spring can be compressed on the tube cover of the test tube and can keep a certain compression force, so that the tube cover can be pressed against and can only not be bounced open when the test tube is heated in a water area;

in order to make the spring support the tube cap more reliably, the upper end face of the box body 1 is provided with 4 positioning holes 7, 4 positioning bolts 6 are arranged on the corresponding positions of the box cover 2 and the positioning holes 7 in a penetrating mode, the positioning bolts 6 are in threaded connection (or in buckling connection) with the positioning holes 7 in a matched mode, the box cover 2 is fixed with the box body 1, and therefore the test tube cap is more reliably compressed.

As shown in fig. 1 and 2, because in some experiments, reagent in the test tube needs the light-resistant use, it has light screen 8 still to swing joint on case lid 2 (the swing joint mode of light screen 8 and case lid 2 can be spout swing joint or articulated mode etc.), light screen 8 is corresponding with the position and the size of the open side of box 1, when case lid 2 lid is on box 1, light screen 8 can block the open side of box 1, thereby carry out the light seal to box 1, make the test tube in the box 1 be in inclosed environment, light screen 8 can also be taken off when not needing the shading, observe the reaction in the test tube when conveniently water bath heating again.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
