As shown in fig. 1-4, the utility model provides a technical solution:

the utility model provides a chemistry experiment test tube storage device, including test tube rack 2, test tube rack 2 is including placing bottom plate 205, place a series of bottom magnetic sheet 204 of one side top fixedly connected with of bottom plate 205, a series of magnetic sheet 206 that rise of opposite side top fixedly connected with, and all include a lantern ring socle 207 in every magnetic sheet 206 that rises, in this embodiment, this lantern ring socle 207 should also have certain magnetism, a test tube bottom gasket 203 of all fixedly connected with in the top of every bottom magnetic sheet 204, in this embodiment, the diameter of bottom magnetic sheet 204 will obviously be greater than test tube bottom gasket 203, and the upper surface of test tube bottom gasket 203 forms the arcwall face of bowl form, so that laminate with the bottom surface of test tube, play spacing guard's effect to the bottom of test tube. The outside of each lantern ring sleeve post 207 slides and is cup jointed with a series of magnetic lantern rings 261, and the top of each magnetic lantern ring 261 all is fixedly connected with a lift gasket 262, and the gasket is accomodate the groove 263 all to have seted up the bottom. In this embodiment, all the raised spacers 262 have the same size as the space defined by the inner walls of the spacer receiving grooves 263, and all the test tube bottom spacers 203 have a smaller height and an outer diameter than those of the raised spacers 262. And raised pad 262 also has the same bowl-like upper profile as tube bottom pad 203. In practical use, when several raised magnetic pieces 206 are stacked together, the raised spacer 262 above each magnetic collar 261 will naturally sink into the spacer receiving groove 263 below the previous magnetic collar 261, so that the magnetic collars 261 are closely arranged. When the test tube is to be received, one raised magnetic plate 206 is required to be placed above the bottom magnetic plate 204, so that the bottom gasket 203 of the test tube is naturally immersed in the gasket receiving groove 263 below the raised magnetic plate 206, and then other raised magnetic plates 206 are stacked on the raised magnetic plate 206, thereby forming a pedestal which is used for supporting feet, and the height of the pedestal can be freely controlled to adapt to test tubes with various lengths and support the bottom end of the test tube.

Place the top both sides of bottom plate 205 one respectively fixedly connected with place the side bearer, two place between the side bearer common fixedly connected with rack top cap 201, seted up a series of test tubes on the rack top cap 201 and placed hole 202. Each of the tube placing holes 202 has a tube inserted therein, and the tube placing hole 202 has a large inner diameter so that the outer wall of the tube does not directly contact with the tube placing hole 202. The top fixedly connected with of rack top cap 201 has a series of test tube clamping device 1, including centre gripping clitellum 107, every centre gripping clitellum 107 all corresponds a test tube and places hole 202, and the outside winding has tightening belt 106, and the common fixedly connected with in both ends of tightening belt 106 tightens up even piece 103. The outer side of the tightening belt 106 is connected with a tightening push block 101 in a sliding manner, the bottom end of the tightening push block 101 is fixedly connected with a tightening slide block 102, and the bottom end of the tightening slide block 102 is connected with the top end of the placing rack top cover 201 in a sliding manner. When the tightening push block 101 is pushed, the space of the approximate circle surrounded by the tightening belt 106 is reduced, and finally the clamping ring belt 107 is in close contact with the outer surface of the test tube, and the clamping ring belt 107 is made of elastic and soft materials, can stretch under the driving of the tightening belt 106, and can protect the wall of the test tube. The bottom end of the placing frame top cover 201 is fixedly connected with a series of clamping top rings 105, each clamping top ring 105 corresponds to one test tube placing hole 202, and the bottom end is fixedly connected with a series of elastic clamping arms 104. The bottom end of the elastic clamping arm 104 is retracted inwards and presents an arc-shaped profile, so that the tube wall can be clamped and simultaneously the up-and-down motion of the test tube can be met.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
