[0036] like Figures 1 to 5 As shown, a test tube rack for clinical testing includes a base plate 1, a counterweight block is arranged inside the base plate 1 to support the test tube rack on a plane to improve the stability of the test tube rack, a lifting assembly 2 fixed on the surface of the base plate 1 is provided with a fixed frame 201 to control the rotation of a screw rod 203 through a knob 202 at its upper end, so that a screw sleeve 204 threadedly connected to the surface of the screw rod 203 can drive the support frame 3 to rise and fall through a fixed linkage block 205, and a straight groove 301 is provided on the surface of the support frame 3 to be clamped on the inner side thereof through a slide bar 401 arranged on the surface of a test tube slot 4, and a limiting clamping plate 402 is arranged on the surface of the test tube slot 4 to be clamped above the support frame 3, an adjusting member 5 located on the inner side of the test tube slot 4 is provided with a toggle member 501, and a linkage ring 503 fixed at one end is driven to move through the toggle member 501, and a long spring 505 is arranged on the upper surface of the linkage ring 503 to connect a rotating ring 506, so that it can move through a limiting ring 507 fixed on the surrounding surface, and a bottom pad 6 is arranged on the surface of the base plate 1 to be located below the test tube slot 4.

[0037] The linkage block 205 on the other side is slidably connected to a limiting rod 206 inside the fixing frame 201 fixed at the middle position, and a buckle assembly 207 is provided on the surface of the knob 202 .

[0038] Through the above technical solution, by setting the limiting rod 206, the position of the support frame 3 can be controlled during the lifting process of the lifting assembly 2 to prevent it from rotating together with the screw rod 203.

[0039] The buckle assembly 207 is provided with a clamping piece 271 clamped on the surface of the knob 202, and the clamping piece 271 rotates on the surface of a fixed shaft 272 fixed on the surface of the fixed frame 201, and a moving block 273 is provided at the other end of the clamping piece 271 to connect with a short spring 274 fixed on the inner side of the fixed frame 201.

[0040] Through the above technical solution, under the elastic support of the short spring 274, the clamping member 271 rotating around the fixed axis 272 is clamped on the surface of the knob 202 to limit the position of the knob 202 to prevent it from sliding again after adjusting the height.

[0041] The inner bottom end of the test tube slot 4 is connected to the spring piece 404 via a fixed fixing ring 403 .

[0042] Through the above technical solution, under the setting of the fixing ring 403, the spring piece 404 can be attached to the surface of the test tube, and the test tube is fixed by using its elastic support characteristics.

[0043] The first slide groove 502 provided on the surface of the test tube groove 4 enables the toggle member 501 to slide inside the slide groove 502, and the second slide groove 504 inside the test tube groove 4 enables the linkage ring 503 to be slidably connected inside the slide groove 504.

[0044] Through the above technical solution, by utilizing the limiting functions of the slide groove 1 502 and the slide groove 2 504 , the linkage ring 503 can slide more smoothly through the toggle member 501 , thereby improving the stability of the adjustment member 5 when adjusting the position of the test tube.

Press the clamp 271 close to one end of the moving block 273, and under the elastic force of the short spring 274, the clamp 271 is disengaged from the clamping connection with the knob 202, so that the knob 202 can be rotated, thereby driving the screw 203 to rotate, so that the surface screw sleeve 204 can drive the support frame through the linkage block 205. The height of the test tube slot 4 can be adjusted by lifting and lowering, so that the test tube slot 4 can be adapted to test tubes of different lengths and the test tubes can be placed. When the test tube needs to be taken, the toggle member 501 can slide inside the slide slot 1 502 under the cooperation of the slide slot 1 502 and the slide slot 2 504, and the long spring 505 is squeezed to move upward. Through the fitted linkage ring 503, under the limit of the slide slot 2 504, the rotating ring 506 can cooperate with the linkage ring 503 to clamp the toggle member 501 at the upper end position of the slide slot 1 502, so that the test tube is moved upward for easy taking.
