DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of the test tube rack provided by the utility model; Figure 2It is a structural schematic diagram of the base in the utility model; Figure 3 This is a schematic diagram of the bottom structure of the top plate in the utility model; Figure 4 The figure is a schematic diagram of the structure of the reinforcement member in the utility model. A test tube rack comprises a base 1, a top plate 2 is arranged on the top of the base 1, a clamping hole 3 is arranged inside the base 1 and the top plate 2, and a test tube 4 is clamped inside the clamping hole 3; a connecting member 5 is arranged between the base 1 and the top plate 2, and a reinforcement member 6 for improving the firmness of the test tube 4 is arranged on the outer side of the connecting member 5.

[0022] It should be noted that: the top plate 2 is limited and fixed on the top of the base 1 by using the connecting piece 5, and the test tube 4 is inserted into the clamping hole 3 on the base 1 and the top plate 2. When the test tube rack is not in use, the top plate 2 is removed from the connecting piece 5, and then the connecting piece 5 is folded and stored to put away the test tube rack to reduce space. The reinforcement piece 6 can be used to improve the stability of the entire test tube rack.

[0023] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the connecting member 5 includes a fixed block 501 fixedly connected to the top of the base 1, the internal rotation of the fixed block 501 is connected to a support ring 502, and the outer side of the top plate 2 is fixedly connected to a buckle 503; the connecting member 5 also includes an anti-slip sleeve 504 fixedly connected to the outer side of the support ring 502.

[0024] It should be noted that: when unfolding the test tube rack, the support ring 502 is lifted up to a vertical state, and then the buckle 503 at the bottom of the top plate 2 is snapped onto the outside of the anti-slip sleeve 504 on the support ring 502, so as to unfold the test tube rack. When storing, the buckle 503 on the top plate 2 is pulled out from the anti-slip sleeve 504, and then the support ring 502 is laid flat to complete the storage of the test tube rack.

[0025] refer to Figure 1 and Figure 4 As shown, the reinforcement 6 includes a fixed frame 601 which is clamped on the outside of the support ring 502, the interior of the fixed frame 601 is fixedly connected to a limiting rod 602, and the outside of the fixed frame 601 is rotatably connected to a closing rod 603; a fixing bolt 604 is arranged inside the closing rod 603, and the fixing bolt 604 passes through the closing rod 603 and the fixed frame 601; the inner walls of the fixed frame 601 and the closing rod 603 are both provided with a clamping groove 605; the outer side of the limiting rod 602 is fixedly connected to a rubber protective sleeve 606, and the inside of the top plate 2 is provided with a buckle groove 7.

[0026] It should be noted that: after the top plate 2 is installed to the outside of the support ring 502, the user passes the fixing frame 601 through the outside of the support ring 502 on one side, and then rotates the closing rod 603 to snap into the outside of the support ring 502 on the other side, and then uses the fixing bolt 604 to connect the closing rod 603 and the fixing frame 601 together, and uses the limiting rod 602 inside the fixing frame 601 to separate each test tube, thereby improving the stability of the test tube and preventing the test tube from shaking and affecting its use. By providing a buckle groove 7 inside the top plate 2, it is convenient for the user to take the top plate 2 for installation and disassembly.

[0027] The working principle of a test tube rack provided by the utility model is as follows:

[0028] When unfolding the test tube rack, the support ring 502 is lifted up to a vertical state, and then the buckle 503 at the bottom of the top plate 2 is snapped onto the outside of the anti-slip sleeve 504 on the support ring 502, so as to unfold the test tube rack. After the top plate 2 is installed to the outside of the support ring 502, the user passes the fixing frame 601 through the outside of the support ring 502 on one side, and then rotates the closing rod 603 to snap onto the outside of the support ring 502 on the other side, and then uses the fixing bolt 604 to connect the closing rod 603 and the fixing frame 601 together. The limiting rod 602 inside the frame 601 separates each test tube 4, improves the stability of the test tube, and prevents the test tube 4 from shaking and affecting its use. By arranging a buckle groove 7 inside the top plate 2, it is convenient for the user to take the top plate 2 for installation and removal. When storing, the buckle 503 on the top plate 2 is pulled out from the anti-slip sleeve 504, and then the support ring 502 is laid flat to complete the storage of the test tube rack, and then the buckle 503 at the bottom of the top plate 2 is clamped into the anti-slip sleeve 504 at the bottom of the support ring 502 to limit the top plate 2.
